Feynman was a genius, regardless of what he says about his IQ. Someone who can break down complex topics like that, and was brought onto work on the Manhattan project t such a young age, shows it, and also his Nobel prize of course. He was elite. But we all run our own races, and don't need to compare to others.
I went back to school for mechanical engineering at 30. I struggled for a few semesters, but once I found Feinmans technique it really changed the game. I used to just jump to trying to solve a problem without fully understanding it. The thechnique showed me how to slow down and follow the procedure. Being able to recognize similar problems helped a lot too. I used to turn 1 problem into 3 by swapping out unknowns and trying to solve the problem from all different angles. I LOVED this video. I watched the entire thing without skipping. You're enthusiasm and delivery is what sucked me in. You got a like and a subscription. I cant wait to watch more of your videos and learn about your work. Wish you the best, man.
Wow you are really an inspiration, Im 17 and I wasted year of my high school due to which im behind most of my classmates and the place where i live most of the people have this idea of now or never so it wont be wrong to say that most of them have already given up on me but tysm this comment really made me understand and see why i chose my subjects in the first place which was not to get ahead of my class or get grades but the goal was simple i chose it to study it and thats it no expectations no mess!
I have lost count of the number of videos I have watched that tried to explain the Feynman Technique, but none has come close to your level of clarity. Thanks!
I've been at the local strip joint for 6 months now. I've spent a fortune, learned nothing, and was just informed I have been expelled by my University.
One trick I like for improving is in taking notes with the aim of finding ideas from the notes worth memorizing. I end up having to simplify and rethink a list of ideas I want to remember as it is more efficient to remember logically, vs. ideas I don't take the time to connect to each other.
That's a very profficient technique, but I have trouble underlining the simple ideas in my head as I get way to caught up in the broader details of it and often, I end up thinking that I may have missed some major key points that could've had my attention switch to immediatly.
@@faroukgo4988 Yeah. I sometimes have to repeat parts of a video to get down what is said. Also, I have a process where I repeatedly go over the same idea but with a different mindset each time. For taking notes from a book or web page (or video) (1st pass), I tend to start by copy-pasting into a word document the parts I found interesting. Then (2nd pass), I reread those notes and organize them into a subset of what I want to memorize or act upon, and put those in a separate document. If I think it's a great note but just not for memorizing or acting upon at this time, I bold it and move on. This last part helps me if the topic becomes more relevant to me in the future. It also helps if I decide to write a book on the topic. It is basically the first step of writing a book, researching and condensing notes. I think this should dramatically reduce the book writing problem of motivation that many writers seem to express. Then (3rd pass), for the memorization section, my current process is set up a Q&A to self-quiz. I like to focus on definitions as a start. I also try to create lists of related ideas for a question, as I can do a trick on them. The trick is to find a logical connection or create a spectrum that is a theme of that list. Reorganize the list until there is some internal logic to it, where I can then recall that logic to more easily remember the list and take much less time than brute force memorization. An example would be if I had a grocery list of milk, eggs, oranges, pears, avocados, and canned beans. One could order the list from least sweetest to sweetest. Another trick is use the method of chunking, meaning divide the list (and subdivide if necessary) until one has categories of at most 3-4 items (like how one can remember a telephone number). So, one could have categories of no sweetness, mild sweetness, and lots of sweetness, or do just lesser sweetness and greater sweetness, 2 categories instead of 3 or vice versa. The skill of categorization. So in general, I think repetition of seeing ideas but through a different lens each time is the key to deeply understanding a topic. This is just my system to be more efficient.
@@mintee8638 wow! Quite surprisingly my approach is very similar to yours but currently im facing a lot of issues with it as high schooler there is a lot you learn in physics chemistry and maths meaning you dont learn each topic deeply but rather you learn a lot of topics at least that happens in our edu system. I cant help but dive deep into every such concept but then that results in me falling behind the others...I dont know your age maybe you are older than me...can you pls advice on how to deal with this or if you are willing can we please connect through any social media because it's really the first time I've found someone who thinks about things so much like i do
@@madhavikawade8149 I am older, but I do want to help those in high school/college. As a heads up, the following stuff stuff can feel a bit random, mainly because it touches a number of tangents. I think Tiago Forte seems to have a roughly similar style if you want to look him up. One UA-cam channel I like for study tips is Justin Sung. If I were to learn phyiscs, chemistry, and math again, I would look for a subject that can apply to my own life today. For each of them, understand the main concepts and not the details like how to calculate. Calculating is a useful skill, but that only needs to be in one subject. I think the problem with education is that a topic tends to lack 2 qualities: (1) enough context, and (2) motivation. For chemistry, the context and motivation for me would be in health and cooking. By context here I mean being able to do concrete things and test them out while keeping the motivation to do so. My motivation for cooking: We all eat. So, it would be nice to understand what is going on there. What makes it taste good? What makes it healthy or unhealthy? My own rule is if it's something that I do or use regularly, then why not learn about what makes it work? For physics, it is understanding everyday things I use like a car, a rainbow, electrical gadgets, or cooking. For math, I like having the ability to think logically about ideas, looking at arguments, asking how to make them sufficiently strong. I also like the idea of using tools/creativity skills to solve problems. This lacks context and motivation though. What I find that does have context and motivation and fits under math are games. There are math videos that analyze games. I like this because one valid motivation is mastery of doing something well, with skill. A bonus to games is it can be done with a small group (big groups, meaning more than 6 people, seems to have quality issues. This is a principle I've seen in business and elsewhere). Beyond this, there are some subjects schools hardly seem to teach that I wish they would. One book I am currently reading is called Everything in its Place by Dan Charnas. It's my favorite productivity book (better than Atomic Habits). What makes it work for me is it explains things in the context of being a chef. It also makes sense that this book is an effective productivity book, as the standards for a chef are crazy high (a combination of one small mistake can destroy a dish, and customers have a low tolerance for not great food), so they developed those productivity tools by necessity. For learning a subject, what I find matters is finding the best teachers/resources in explaining that subject. I use books, videos, and websites. My way of measuring this is how many notes do I take. It can get easy to get sucked into a video that I don't take notes on, and that can be ok either as a mistake to reflect and learn from or as a way to learn the topic of storytelling and business in terms of what did they do that kept me watching them. I would say don't worry about school that much as they don't do the best job. Two important skills worth developing are communication and being active and not passive in one's life (this is a good chess principle as well). For example, with your teachers, when you find a good book or resource, tell them how that motivates you and see if there's a way to be able to go more into that as part of your grade. The teacher would probably be interested in looking at something they don't typically look at. They may get some ideas that would improve their teaching. What I would say is treat them how one should treat a boss, meaning to explicitly ask them how one can make their teaching/grading life easier when doing this task that is different from the class, such as making a grading rubric for them. I would say work with them as early as possible as this gives them more flexibility on that situation. I would imagine that good teachers love a student taking initiative because it can be less boring work and more interesting work for the teacher, and the student tends to grow way more in being active. There is this idea of active learning as being better than passive learning in general. One can search John Dunlosky and 10 studying techniques that he analyzes. I refer to a table towards the end of one of his papers. The table has the letters PINQ. What I took from an analysis of those techniques is that with the content itself, the more active learning techniques do better than the more passive ones. Outside of the content, there are some passive techniques that make a big difference, such as spacing learning out and practicing to mimic the actual situation. For example, a practice test mimics the actual test. This also applies to mimicking the environment of the actual test, meaning practicing in a noisy room helps if the actual situation involves lots of noise and distractions.
@@mintee8638 Ok sir, you honestly gave me food for thought and I just don't want to miss any of your points mentioned. I definitely will research and reflect upon them and see what works best for me. You are really so kind to have typed that long and share your experiences with me, it really means a lot! Will keep you updated on this!
Absolutely excellent! I discovered this when I was in grad school and had to teach. If you teach effectively you have to organize effectively. Thank you bro!!
Great Video. I highly recommend the book „How to solve it“ by George Polya, one of the greatest mathematicians in the 20th century and a great teacher at the same time.
Man, you humiliated me with that simple problem, where I had to actually write down the problem and understand the concepts in order to solve it. There was a time when i could do it mentally, and write down the final formula, doing it in one line. Many years of not doing probability questions has finally come back to bite me. Thank you !
As a gold medal winner at the International Mathematical Olympiad of this year, I guess I'm experienced at this field. The Feynman method is basically a combination of two methods: Analysing the question and analyse your weaknesses. Analysing the question by writing it down and possibly restating the question is required when there is some useless information, which is even the case for some Mathematics questions. Remember that the IMO fits on a single piece of paper, using both sides for both days, which is DEFINITELY not the case for the Physics Olympiad. You simply can't use Mathematics on words. There is also the known Psychological effect, that we assume things are more important when we wrote them down. The other part is more important, because it is required to improve your skills. In Mathematics, I once in a while come back at a group of connected theorems, and try to find the easiest way to prove them, as a challenge. Thinking about a subject in every way possible is the best method to make you good at something. Thinking and rethinking makes sure you become faster at those steps. This is essential when you are young. Another important part, which is not part of Feynman's method is practise. Do it. It's like sleeping: extremely important, but everybody hates it, because it feels useless (I am typing this at 0:32 AM, tomorrow university 😅)
@@thetenrings There aren't any specific books you would want to read. The most important part when training for any Olympiad is being able to quickly and consistently solve the relatively simple problems, make sure the problems in the book aren't too hard.
I forgot the formula and didn’t understand the formula meaning when I took this class. Fortunately, I took the class in summer and the Professor didn’t teach it and didn’t require us to hand it. But looks like today I learned something about it so clearly. Thanks for giving us some good methods to study. I am thinking I have to review my calculus before I take the Econ 11 class one week later. Thanks again
Most important thing is we should understand the problem. It happened to me so many times i failed to solve some simple problems. i remember i could not solve a simple problem in probability because i was unable to understand the English sentences. Google helps us.
Great video mate, you are very articulated and you explain concepts in a clear and concise manner thanks. I can see you becoming a highly successful UA-camr.
Samuel not being entirely sure about sensitivity and specificity is really sympathetic. I also have to write it down and infer it from a confusion matrix to not get confused all the time😁😂
@Shimmy Shai Im not him obviously, but I happen to agree with his statement. On the other hand, I think that instantly making a connection between the utility and importance of those two things in your own life and judging other people is a mistake. In general, I think judging other people on (in the end) moral grounds is illogical. Rationally, you might know (or statistically be able to assume) that you are better at math than the jock or better at getting girls than the nerd, but if you look down on other people for their perceived inferiority, you let your emotions and ego get in the way of your actions, making you act more irrationally and less in your long term self interest by underestimating them or disregarding useful points they bring up. They may be worse in some things than you, but never let that get to your head. As for the individual payoff, I study math, so fitness is a vanity project that takes far less of my time compared to my studies. A model or athlete might view studying physics the same. Something interesting on the side, but not the center of his life. Also, both education and fitness have large front up payoffs that make investing into either at least a little very worthwhile. Having a basic college degree from any university is gonna improve your income vastly compared to a highschool dropout. Doing cardio 3 times a week is a huge health improvement compared to not working out at all. So even taking those and stopping after returns start to diminish is pretty logical for either.
@Shimmy Shai Well, I dont agree with your moralizing either. I do not need to accept or praise diversity either. It exists and any moral judgement I make is pointless, because it wastes time I could spend on other things. I believe that morality in general, and absolute moral axioms in particular, are useuless and effectively hinder decision making. So, I make no judgement, because I dont have to. Judging doesnt help me, it doesnt relate to my own life. Abscense of judgement does not mean acceptance, it means tolerance for lack of better alternatives. If, at no cost on my own, I could make all ugly and out of shape people disappear, I probably would. But I simply dont care enough about other people to waste time on judgement, that even without the time cost, would still negatively affect my decision making. As for working out, health benefits were my first argument, because they are universally useful. That was my argument about diminishing returns, doing some physical activity always benefits you because of your health. Since working out beyond that health impact mostly just influences your looks, its your call to make if those smaller aesthetic returns are still worth investing more. For me, they are. Im vain, I want to look good, lol. As for bodybuilding, sure, after a certain point, like everything, rising cost outweigh rising profits and its logical to stop. And some people dont, but they are the ones that pay the price anyway. As an additional point, even beyond health concerns, after a certain amount of gains, your body overblows the proportions that are on average seen as aesthetic. Thats why few people actually find (hardcore) bodybuilders attractive.
@Shimmy Shai I try to be as clear, logical and consistent as possible myself, because in the end, not being those things makes you choose wrong. And whats life but a game of resources and choice optimization? So I hope I was able to communicate my points well.
WOW Klasse Content . Bin gerade am Gymnasium und habe dich durch Niklas Steenfat kennengelernt . Das ist Content der Generationen motiviert an sich zu arbeiten und die beste Version von sich selber zu werden . Mein Abo ist aufjedenfall gesichert❤
Great videos, I really hope you don't stop producing high quality content! Many clicks might mean that more people watch it and that some people like it better but the reason could be that it is "easier" content (to consume) rather than more meaningful content which would positively change someones life. So please keep that in mind!
Feynman technique is legit. I applied it for my mom, and guess what, I found why I was getting the problem wrong and found where I was wrong and did the problem right.
Amazing video. So informative and educative .Keep up your good spirit.Listening to you is worth it .Your concepts are very clear and no wonder your listeners have no difficulty in understanding them
thank you for mentioning an example!! it helped so much! I usually struggle to understand a concept without seeing the application of it, so thank you!!
Also,I totally find myself on the wavelength of the students who are all about understanding STEM and later on due to not remembering have to look up the textbook or the notes again.I understand all the concepts being taught in class and it's all well then,but since I don't write the solution down, I'm not able to remember them clearly. I totally have been overlooking the part of writing and how crucial it is.Thank you.
Great video! Do you have any tips on how to work on the speed of logic behind problem solving? For example, it took me some time for me to grasp what the statistics in the first question even meant conceptually in the first place. Do you have any tips on improving the intuitive conceptual understanding behind certain problems?
Have a look at my video about understanding math intuitively. Also, if you wanna get better at calculating probabilities, there is no way around lots of problem solving practice in this area 🙂
everyone should note that IQ doesn't measure overall intelligence, it is just a temporary score on one type of puzzle skill. if you practice the test a few times you can go from 70 to 130 in a week, with an official proctor, because it is not measuring anything static or biological you'll find people with advanced degrees and actual publications/award's don't ever care about "iq scores", since they know it is meaningless in academics. anyone who is neurotypical and motivated, and has necessary resources, will do well in their studies. don't let poor instruction from the past make you think certain subjects are beyond you i suggest people unsure about their intelligence to study philosophy, since it will teach basic propositional logic and epistemology, which will aid in all aspects of your learning
I think this was Feynman’s way of mocking the IQ score system. It’s completely meaningless, and I’ve never met anyone at Harvard or MIT (a place where you would expect the smartest people on this planet) who ever cared about their IQ
Its a bit contradicting that Feynman had an IQ of 124 (slightly above the standdard deviation of IQ measurements from the average) but is being used as an example of extreme superior problemsolving (also often being mentioned by Stephan Wolfram), which is supposed to be the exact statement of the IQ Test
I agree. It could be that Feynman’s IQ was actually higher. Or it could also be an indication that the way we measure IQs is not accurate and meaningful at all
@@sylwek1177 actually I think a lot of us can.. obviously it doesn’t happen overnight, but with active practice and diligence who knows what strategies people can discover for themselves.. I myself have become a lot smarter over the past 1.5 years I understand concepts really fast and am able to solve novel problems within that topic, minutes after learning it. I’m no genius, and I know that for sure becuase 1.5 years ago, I didn’t even understand basic Trigonometry… I rejected anything that had to do with learning and using my brain for my whole life… I deprived myself from intellect until i found multiple sparks that led me to craving it. Since then I’ve come across hundreds of problems, with school, and life… solving them became my priority, I would try my best without help, I would use my brain till it hurt.. I would take breaks, and come back and re approach the problems.. succeeding in some and failing in others. Ultimately I have figured out patterns overtime and am the most efficient I have ever been. Just for more perspective of how one can get drastically smarter I’m an 2nd year engineering student with a 4.0 gpa who got a 1100 on the SAT
@@william_SMMA lol bro, my whole point was that I’m dumb and got as low as a 1100, but have gotten smarter over time and now maintain a 4.0 gpa in college (I know grades don’t necessarily equate to intelligence but I don’t cheat, or rely too much on the internet I use my head
I know this approach is attributed to Feynman, but I don’t think he ever described it - at least not in text. I think the spread of this attribution to Feynman is because ppl don’t fact check stuff do a reasonable degree but see something somewhere and retell it. Do you know of any place where Feynman described this approach?
@@1sor Sure. But to my knowledge Feynman never formulated this 'Feynman approach' that is attributed to him. Your post does not address that. Btw, I'm a big fan of Feynman, just not a fan of misattribution and believe that we should not spread misinformation.
@@SamuelBoschMIT Thank you! I was wondering which field to dive deep into for research, such that in case if I'm forced to do a job in the same field later on, atleast, the job should require me to keep learning throughout my career as opposed to reaching a ceiling. Which field do you think would offer this kind of versatility?
You are an IPHO Medalist?? In many of your videos you have portrayed that you are not that good. That's really good to know and no wonder why you got into MIT. Also your way of speaking is very cyrstal clear.
I did win 3 IPhO medals actually, but got rejected for my undergrads by MIT :) Have a look at my "life principles for success" video, and my "How to get into MIT as an international" videos for more details
@@M9a3 The admission criteria are sometimes somewhat arbitrary. I know people with just 1 medal (not that it makes a big difference) who got admitted. There are so many factors that decide if you get in. Some of them rational, some of them quite random :)
Steve Hsu says about Feynman's iq: Feynman was universally regarded as one of the fastest-thinking and most creative theorists in his generation. Yet, it has been reported-including by Feynman himself-that he only obtained a score of 125 on a school IQ test. I suspect that this test emphasized verbal, as opposed to mathematical, ability. Feynman received the highest score in the country by a large margin on the notoriously difficult Putnam mathematics competition exam, although he joined the MIT team on short notice and did not prepare for the test. He also reportedly had the highest scores on record on the math/physics graduate admission exams at Princeton. It seems quite possible to me that Feynman's cognitive abilities might have been a bit lopsided - his vocabulary and verbal ability were well above average, but perhaps not as great as his mathematical abilities. I recall looking at excerpts from a notebook Feynman kept while an undergraduate. While the notes covered very advanced topics for an undergraduate - including general relativity and the Dirac equation - it also contained a number of misspellings and grammatical errors. I doubt Feynman cared very much about such things.
I would put it this way: If I were to compete with Feynman on verbal tasks, I would probably still lose but the difference would be measurable. However, if I tried the same on mathematical tasks, you probably could guess how poorly I woul do. Not saying problem solving strategies are not a huge advantage, I love your videos. But we should be realistic - no one with an iq of 124/125 can become the next Feynman here. And btw Samuel, do you know your iq? I think 150+ is reasonable, isnt it?
Hi glad have found this video. I was wondering what skills are required to solve problems in math counts and Olympiad? Can these skills be broken down and learned individually? Also how can somebody know that learning is happening? Thanks.
Hi I have a video idea Could you make a video about how to write a research paper (with how to find a topic) as you have a lot of experience with that It would be really helpful for high school students and I think that this is a topic that would interest a lot of people, it is kinda off topic from the whole channel but it would help Here in Croatia, as you probably know, no one does this so it is really hard to write a research paper with no experience and no one to ask for help.
Hey Samuel, really nice job explaining the concept! I was calculating the exact thing for friends in Statistics when we talked about false positive COVID-19 tests. They were pretty stunned! But after all, I couldn’t manage to find a proper formula explaining how the probability changes if 1. more Random people (let’s say 10) take a test 2. one person repeatedly takes a test What would be the solution with your given problem and numbers?
Its nice video on solving real life drug test problem with Bayes theorem, your word "only four out of the test are actually correct a bit confusing" at 12:07. Do you mean actually only one? Thanks anyway
I let my mind speak freely here now. 90% sensitivity means that out of the drug-users 90% will be positive. On the other hand, 80% specificity means that 20% of the non-users will be positive as well. Because the initial condition is the most important one - by which I mean that only 5% of the population are drug users, that means that 20% of 95% is the chance to get false positive and 90% of 5% is the chance to get true positive. By calculating in my head it seems that the chance of getting false positive is 19% and of getting true positive is 4.5% . The conclusion: if we tested someone randomly and he was tested positive , the chance that he really a drug user is only 4.5/23.5 = 19.14% . That means that the chance that positively tested individual is NOT using drugs is 4 times higher than the chance that he uses drugs. Or in other words the chance for False positive is 4 times higher than real true positive. That is not a good way to identify drug users
Good video and something everyone should strive to learn for their life. Technical communication is an extremely valuable skill for tech teams working with multiple fields but also useful in daily life.
@12:08 you said “that means that only four out of five of the tests are actually correct “ shouldn’t it have been “ are not correct” as the probability is around 20% I.e 1 out of 5 is correct and 4 out of 5 are incorrect as the incorrect probability is 80%. Can someone please explain if I am getting something wrong? at the start of the problem he said closer to 1 is good but 4/5 is 80% and is close to 1.
1:22 I think that’s a proof that iq doesn’t measure intelligence that well, not a proof that he wasn’t super smart in the first place. He won the Putnam and a Nobel prize
I always think of learning something new like a torrent downloading a file it's not linear you'll understand something here and there and there are missing pieces of the puzzle which connects the dots PS: one could also use Bayes theorem in learning new things we keep updating what we already know until we know the ultimate truth
How do you use Ank, when you are not doing exams? Are there good websites to find Anki decks for introductory courses (making decks takes so much time)?
can we do an average of the error ( of the specifity and the sensitivityty) so 0,10 and 0.20, the average is an 0.15 probability of error. And we can do 0.15 * 0.95 (the population who don't consume drugs), and if it's superior at 5% it's mean that there is more people who will know an error in their test than the people who actually consume drugs. Cause if you are tested negative and you are really positive it's as bad than if you are tested positif but you are really negative
Hey, im curious is there some trick/method in math with as huge impact as memory palace for improving memory? Ive heard of abakus and some japanesse verion of this tool which basically changes numbers to images and enables people to do huge mental calculations. I would be so grateful if you could recommend some starting resources :) thanks for great content :)
You're telling me one of the greatest physicists of all time had an IQ less than mine?!?! (133 according to Mensa. Not sure how accurate that one is. IQ is overrated anyway but still.) I was fired from a fast food job when I was 17 cause I was terrible lol. There is no way.
I didn't understand the part where you say 190 people as "False positives"?? But they are under "Not using drugs" category, so they have to be "False negatives" right? Is this error in video or am I missing something?? Coz, let's say a drug test is conducted between 1000 people, 950 people don't use drugs means they got negative in test result and 50 people use drugs means test came back positive for them. So in these 950 people, 20% are false negatives which means those 20% people actually take drugs but in the test they came as back as "not using drugs", this is the meaning of false negative... And I understood the part of true positives, coz in 50 people 90% people do actually take drugs but the other 10% are false positives, which means those 10% people don't take drugs but they falsely came as positive in the test, so 45 people are true positives and 190 people are false negatives... In total, 235 people do take drugs. Am I right? Please correct me, if I'm wrong.

I've been at the local strip joint for 6 months now. I've spent a fortune, learned nothing, and was just informed I have been expelled by my University.
One trick I like for improving is in taking notes with the aim of finding ideas from the notes worth memorizing. I end up having to simplify and rethink a list of ideas I want to remember as it is more efficient to remember logically, vs. ideas I don't take the time to connect to each other.
That's a very profficient technique, but I have trouble underlining the simple ideas in my head as I get way to caught up in the broader details of it and often, I end up thinking that I may have missed some major key points that could've had my attention switch to immediatly.
@@faroukgo4988 Yeah. I sometimes have to repeat parts of a video to get down what is said. Also, I have a process where I repeatedly go over the same idea but with a different mindset each time.
For taking notes from a book or web page (or video) (1st pass), I tend to start by copy-pasting into a word document the parts I found interesting.
Then (2nd pass), I reread those notes and organize them into a subset of what I want to memorize or act upon, and put those in a separate document. If I think it's a great note but just not for memorizing or acting upon at this time, I bold it and move on. This last part helps me if the topic becomes more relevant to me in the future. It also helps if I decide to write a book on the topic. It is basically the first step of writing a book, researching and condensing notes. I think this should dramatically reduce the book writing problem of motivation that many writers seem to express.
Then (3rd pass), for the memorization section, my current process is set up a Q&A to self-quiz. I like to focus on definitions as a start. I also try to create lists of related ideas for a question, as I can do a trick on them. The trick is to find a logical connection or create a spectrum that is a theme of that list. Reorganize the list until there is some internal logic to it, where I can then recall that logic to more easily remember the list and take much less time than brute force memorization.
An example would be if I had a grocery list of milk, eggs, oranges, pears, avocados, and canned beans. One could order the list from least sweetest to sweetest. Another trick is use the method of chunking, meaning divide the list (and subdivide if necessary) until one has categories of at most 3-4 items (like how one can remember a telephone number). So, one could have categories of no sweetness, mild sweetness, and lots of sweetness, or do just lesser sweetness and greater sweetness, 2 categories instead of 3 or vice versa. The skill of categorization.
So in general, I think repetition of seeing ideas but through a different lens each time is the key to deeply understanding a topic. This is just my system to be more efficient.
@@mintee8638 wow! Quite surprisingly my approach is very similar to yours but currently im facing a lot of issues with it as high schooler there is a lot you learn in physics chemistry and maths meaning you dont learn each topic deeply but rather you learn a lot of topics at least that happens in our edu system. I cant help but dive deep into every such concept but then that results in me falling behind the others...I dont know your age maybe you are older than me...can you pls advice on how to deal with this or if you are willing can we please connect through any social media because it's really the first time I've found someone who thinks about things so much like i do
@@madhavikawade8149 I am older, but I do want to help those in high school/college.
As a heads up, the following stuff stuff can feel a bit random, mainly because it touches a number of tangents.
I think Tiago Forte seems to have a roughly similar style if you want to look him up. One UA-cam channel I like for study tips is Justin Sung.
If I were to learn phyiscs, chemistry, and math again, I would look for a subject that can apply to my own life today. For each of them, understand the main concepts and not the details like how to calculate. Calculating is a useful skill, but that only needs to be in one subject.
I think the problem with education is that a topic tends to lack 2 qualities: (1) enough context, and (2) motivation.
For chemistry, the context and motivation for me would be in health and cooking. By context here I mean being able to do concrete things and test them out while keeping the motivation to do so.
My motivation for cooking: We all eat. So, it would be nice to understand what is going on there. What makes it taste good? What makes it healthy or unhealthy?
My own rule is if it's something that I do or use regularly, then why not learn about what makes it work?
For physics, it is understanding everyday things I use like a car, a rainbow, electrical gadgets, or cooking.
For math, I like having the ability to think logically about ideas, looking at arguments, asking how to make them sufficiently strong. I also like the idea of using tools/creativity skills to solve problems. This lacks context and motivation though.
What I find that does have context and motivation and fits under math are games. There are math videos that analyze games. I like this because one valid motivation is mastery of doing something well, with skill. A bonus to games is it can be done with a small group (big groups, meaning more than 6 people, seems to have quality issues. This is a principle I've seen in business and elsewhere).
Beyond this, there are some subjects schools hardly seem to teach that I wish they would. One book I am currently reading is called Everything in its Place by Dan Charnas. It's my favorite productivity book (better than Atomic Habits). What makes it work for me is it explains things in the context of being a chef. It also makes sense that this book is an effective productivity book, as the standards for a chef are crazy high (a combination of one small mistake can destroy a dish, and customers have a low tolerance for not great food), so they developed those productivity tools by necessity.
For learning a subject, what I find matters is finding the best teachers/resources in explaining that subject. I use books, videos, and websites. My way of measuring this is how many notes do I take.
It can get easy to get sucked into a video that I don't take notes on, and that can be ok either as a mistake to reflect and learn from or as a way to learn the topic of storytelling and business in terms of what did they do that kept me watching them.
I would say don't worry about school that much as they don't do the best job. Two important skills worth developing are communication and being active and not passive in one's life (this is a good chess principle as well). For example, with your teachers, when you find a good book or resource, tell them how that motivates you and see if there's a way to be able to go more into that as part of your grade.
The teacher would probably be interested in looking at something they don't typically look at. They may get some ideas that would improve their teaching. What I would say is treat them how one should treat a boss, meaning to explicitly ask them how one can make their teaching/grading life easier when doing this task that is different from the class, such as making a grading rubric for them. I would say work with them as early as possible as this gives them more flexibility on that situation.
I would imagine that good teachers love a student taking initiative because it can be less boring work and more interesting work for the teacher, and the student tends to grow way more in being active. There is this idea of active learning as being better than passive learning in general.
One can search John Dunlosky and 10 studying techniques that he analyzes. I refer to a table towards the end of one of his papers. The table has the letters PINQ. What I took from an analysis of those techniques is that with the content itself, the more active learning techniques do better than the more passive ones. Outside of the content, there are some passive techniques that make a big difference, such as spacing learning out and practicing to mimic the actual situation. For example, a practice test mimics the actual test. This also applies to mimicking the environment of the actual test, meaning practicing in a noisy room helps if the actual situation involves lots of noise and distractions.
@@mintee8638 Ok sir, you honestly gave me food for thought and I just don't want to miss any of your points mentioned. I definitely will research and reflect upon them and see what works best for me.

Great Video. I highly recommend the book „How to solve it“ by George Polya, one of the greatest mathematicians in the 20th century and a great teacher at the same time.
Thanks for the recommendation Luca 🙂
Man, you humiliated me with that simple problem, where I had to actually write down the problem and understand the concepts in order to solve it. There was a time when i could do it mentally, and write down the final formula, doing it in one line. Many years of not doing probability questions has finally come back to bite me. Thank you !
Hahhahhahah it's the same for me 😂 A few years ago, i would have done that in my head
study physics
As a gold medal winner at the International Mathematical Olympiad of this year, I guess I'm experienced at this field.
The Feynman method is basically a combination of two methods: Analysing the question and analyse your weaknesses.
Analysing the question by writing it down and possibly restating the question is required when there is some useless information, which is even the case for some Mathematics questions. Remember that the IMO fits on a single piece of paper, using both sides for both days, which is DEFINITELY not the case for the Physics Olympiad.
You simply can't use Mathematics on words. There is also the known Psychological effect, that we assume things are more important when we wrote them down.
The other part is more important, because it is required to improve your skills.
In Mathematics, I once in a while come back at a group of connected theorems, and try to find the easiest way to prove them, as a challenge. Thinking about a subject in every way possible is the best method to make you good at something.
Thinking and rethinking makes sure you become faster at those steps. This is essential when you are young.
Another important part, which is not part of Feynman's method is practise. Do it. It's like sleeping: extremely important, but everybody hates it, because it feels useless (I am typing this at 0:32 AM, tomorrow university 😅)
Hey man i am a beginner and i cant even do my nationals problem bro can u help please
Wow a gold imo winner in the comments, I cant even make jmo 💀
Is there any books I should read (textbooks) or any sources of problems except the past papers for IMO?
@@thetenrings There aren't any specific books you would want to read.
The most important part when training for any Olympiad is being able to quickly and consistently solve the relatively simple problems, make sure the problems in the book aren't too hard.
I forgot the formula and didn’t understand the formula meaning when I took this class. Fortunately, I took the class in summer and the Professor didn’t teach it and didn’t require us to hand it. But looks like today I learned something about it so clearly. Thanks for giving us some good methods to study. I am thinking I have to review my calculus before I take the Econ 11 class one week later. Thanks again
Most important thing is we should understand the problem. It happened to me so many times i failed to solve some simple problems. i remember i could not solve a simple problem in probability because i was unable to understand the English sentences. Google helps us.
Great video mate, you are very articulated and you explain concepts in a clear and concise manner thanks. I can see you becoming a highly successful UA-camr.
Thank you 😊
Hello Samuel, still expecting a reply about Physics Olympiad 2014
Samuel not being entirely sure about sensitivity and specificity is really sympathetic. I also have to write it down and infer it from a confusion matrix to not get confused all the time😁😂
I get them confused all the times too 😂
I'm so glad I found your channel! You're buff and highly educated, this is exactly what I aspire to be!
hahahahah that's the way to go dude 💪💪💪😁
@@SamuelBoschMIT please make more videos talking about your diet/ workout routine!
@Shimmy Shai Im not him obviously, but I happen to agree with his statement.
On the other hand, I think that instantly making a connection between the utility and importance of those two things in your own life and judging other people is a mistake. In general, I think judging other people on (in the end) moral grounds is illogical. Rationally, you might know (or statistically be able to assume) that you are better at math than the jock or better at getting girls than the nerd, but if you look down on other people for their perceived inferiority, you let your emotions and ego get in the way of your actions, making you act more irrationally and less in your long term self interest by underestimating them or disregarding useful points they bring up. They may be worse in some things than you, but never let that get to your head.
As for the individual payoff, I study math, so fitness is a vanity project that takes far less of my time compared to my studies. A model or athlete might view studying physics the same. Something interesting on the side, but not the center of his life.
Also, both education and fitness have large front up payoffs that make investing into either at least a little very worthwhile. Having a basic college degree from any university is gonna improve your income vastly compared to a highschool dropout. Doing cardio 3 times a week is a huge health improvement compared to not working out at all. So even taking those and stopping after returns start to diminish is pretty logical for either.
@Shimmy Shai Well, I dont agree with your moralizing either. I do not need to accept or praise diversity either. It exists and any moral judgement I make is pointless, because it wastes time I could spend on other things. I believe that morality in general, and absolute moral axioms in particular, are useuless and effectively hinder decision making. So, I make no judgement, because I dont have to. Judging doesnt help me, it doesnt relate to my own life. Abscense of judgement does not mean acceptance, it means tolerance for lack of better alternatives. If, at no cost on my own, I could make all ugly and out of shape people disappear, I probably would. But I simply dont care enough about other people to waste time on judgement, that even without the time cost, would still negatively affect my decision making.
As for working out, health benefits were my first argument, because they are universally useful. That was my argument about diminishing returns, doing some physical activity always benefits you because of your health. Since working out beyond that health impact mostly just influences your looks, its your call to make if those smaller aesthetic returns are still worth investing more. For me, they are. Im vain, I want to look good, lol.
As for bodybuilding, sure, after a certain point, like everything, rising cost outweigh rising profits and its logical to stop. And some people dont, but they are the ones that pay the price anyway. As an additional point, even beyond health concerns, after a certain amount of gains, your body overblows the proportions that are on average seen as aesthetic. Thats why few people actually find (hardcore) bodybuilders attractive.
@Shimmy Shai I try to be as clear, logical and consistent as possible myself, because in the end, not being those things makes you choose wrong. And whats life but a game of resources and choice optimization? So I hope I was able to communicate my points well.
I'm beyond thankful to you for all the content on your channel. Mr.Samuel,you have my gratitude.

Great video! Do you have any tips on how to work on the speed of logic behind problem solving?

everyone should note that IQ doesn't measure overall intelligence, it is just a temporary score on one type of puzzle skill. if you practice the test a few times you can go from 70 to 130 in a week, with an official proctor, because it is not measuring anything static or biological
you'll find people with advanced degrees and actual publications/award's don't ever care about "iq scores", since they know it is meaningless in academics. anyone who is neurotypical and motivated, and has necessary resources, will do well in their studies. don't let poor instruction from the past make you think certain subjects are beyond you
i suggest people unsure about their intelligence to study philosophy, since it will teach basic propositional logic and epistemology, which will aid in all aspects of your learning
I think this was Feynman’s way of mocking the IQ score system. It’s completely meaningless, and I’ve never met anyone at Harvard or MIT (a place where you would expect the smartest people on this planet) who ever cared about their IQ
Its a bit contradicting that Feynman had an IQ of 124 (slightly above the standdard deviation of IQ measurements from the average) but is being used as an example of extreme superior problemsolving (also often being mentioned by Stephan Wolfram), which is supposed to be the exact statement of the IQ Test
I agree. It could be that Feynman’s IQ was actually higher. Or it could also be an indication that the way we measure IQs is not accurate and meaningful at all
He had at least 150 IQ. You just can't learn to be super smart.
@@sylwek1177 actually I think a lot of us can.. obviously it doesn’t happen overnight, but with active practice and diligence who knows what strategies people can discover for themselves.. I myself have become a lot smarter over the past 1.5 years
I understand concepts really fast and am able to solve novel problems within that topic, minutes after learning it.
I’m no genius, and I know that for sure becuase 1.5 years ago, I didn’t even understand basic Trigonometry…
I rejected anything that had to do with learning and using my brain for my whole life… I deprived myself from intellect until i found multiple sparks that led me to craving it.
Since then I’ve come across hundreds of problems, with school, and life… solving them became my priority, I would try my best without help, I would use my brain till it hurt.. I would take breaks, and come back and re approach the problems.. succeeding in some and failing in others. Ultimately I have figured out patterns overtime and am the most efficient I have ever been.
Just for more perspective of how one can get drastically smarter

I know this approach is attributed to Feynman, but I don’t think he ever described it - at least not in text. I think the spread of this attribution to Feynman is because ppl don’t fact check stuff do a reasonable degree but see something somewhere and retell it.
Do you know of any place where Feynman described this approach?
I do appreciate your explanatory videos. Thx.
Even in his lectures he emphasizes using common words and concepts to explain things as much as possible
@@1sor Sure. But to my knowledge Feynman never formulated this 'Feynman approach' that is attributed to him. Your post does not address that. Btw, I'm a big fan of Feynman, just not a fan of misattribution and believe that we should not spread misinformation.

Steve Hsu says about Feynman's iq:
Feynman was universally regarded as one of the fastest-thinking and most creative theorists in his generation. Yet, it has been reported-including by Feynman himself-that he only obtained a score of 125 on a school IQ test.
I suspect that this test emphasized verbal, as opposed to mathematical, ability. Feynman received the highest score in the country by a large margin on the notoriously difficult Putnam mathematics competition exam, although he joined the MIT team on short notice and did not prepare for the test. He also reportedly had the highest scores on record on the math/physics graduate admission exams at Princeton.
It seems quite possible to me that Feynman's cognitive abilities might have been a bit lopsided - his vocabulary and verbal ability were well above average, but perhaps not as great as his mathematical abilities.
I recall looking at excerpts from a notebook Feynman kept while an undergraduate. While the notes covered very advanced topics for an undergraduate - including general relativity and the Dirac equation - it also contained a number of misspellings and grammatical errors. I doubt Feynman cared very much about such things.
I would put it this way:
If I were to compete with Feynman on verbal tasks, I would probably still lose but the difference would be measurable. However, if I tried the same on mathematical tasks, you probably could guess how poorly I woul do. Not saying problem solving strategies are not a huge advantage, I love your videos. But we should be realistic - no one with an iq of 124/125 can become the next Feynman here. And btw Samuel, do you know your iq? I think 150+ is reasonable, isnt it?
Great vid

Hi
I have a video idea
Could you make a video about how to write a research paper (with how to find a topic) as you have a lot of experience with that
It would be really helpful for high school students and I think that this is a topic that would interest a lot of people, it is kinda off topic from the whole channel but it would help
Here in Croatia, as you probably know, no one does this so it is really hard to write a research paper with no experience and no one to ask for help.
Hey Samuel, really nice job explaining the concept! I was calculating the exact thing for friends in Statistics when we talked about false positive COVID-19 tests. They were pretty stunned!
But after all, I couldn’t manage to find a proper formula explaining how the probability changes if
1. more Random people (let’s say 10) take a test
2. one person repeatedly takes a test
What would be the solution with your given problem and numbers?
So if you never learned Bayes theorem in school, then to solve it, you would have to invent it on the spot here. That would've been more impressive.
Hhahaha yeah, if you’ve never heard about Bayes theorem, solving this would be quite impressive ahahahaha
Hi, What device and app were using to write out your formulas?
Its nice video on solving real life drug test problem with Bayes theorem, your word "only four out of the test are actually correct a bit confusing" at 12:07. Do you mean actually only one? Thanks anyway
Nice I learned a lot keep the good work
Thank you! Btw, a new video focused on learning math is coming out tomorrow 🙂
I let my mind speak freely here now. 90% sensitivity means that out of the drug-users 90% will be positive. On the other hand, 80% specificity means that 20% of the non-users will be positive as well. Because the initial condition is the most important one - by which I mean that only 5% of the population are drug users, that means that 20% of 95% is the chance to get false positive and 90% of 5% is the chance to get true positive. By calculating in my head it seems that the chance of getting false positive is 19% and of getting true positive is 4.5% .
The conclusion: if we tested someone randomly and he was tested positive , the chance that he really a drug user is only 4.5/23.5 = 19.14% .
That means that the chance that positively tested individual is NOT using drugs is 4 times higher than the chance that he uses drugs. Or in other words the chance for False positive is 4 times higher than real true positive.
That is not a good way to identify drug users
I must say that as you presented the problem I stopped the video and solved it here while typing the comment.
Very nice :)

His Iq was only ever tested once where he maxed the test and finish way before everyone else accordingly to the books I've read.
@12:08 you said “that means that only four out of five of the tests are actually correct “ shouldn’t it have been “ are not correct” as the probability is around 20% I.e 1 out of 5 is correct and 4 out of 5 are incorrect as the incorrect probability is 80%. Can someone please explain if I am getting something wrong? at the start of the problem he said closer to 1 is good but 4/5 is 80% and is close to 1.
This is Bayes Theorem of Conditional Probability, right? I studied this in Econ classes.
Yes :)

1:22 I think that’s a proof that iq doesn’t measure intelligence that well, not a proof that he wasn’t super smart in the first place. He won the Putnam and a Nobel prize
This may be true. But it may also be true that he just made up the number, or something like that, and that his IQ is a lot higher

feynmans the dawg
can we do an average of the error ( of the specifity and the sensitivityty) so 0,10 and 0.20, the average is an 0.15 probability of error. And we can do 0.15 * 0.95 (the population who don't consume drugs), and if it's superior at 5% it's mean that there is more people who will know an error in their test than the people who actually consume drugs. Cause if you are tested negative and you are really positive it's as bad than if you are tested positif but you are really negative

I didn't understand the part where you say 190 people as "False positives"??
But they are under "Not using drugs" category, so they have to be "False negatives" right? Is this error in video or am I missing something??
Coz, let's say a drug test is conducted between 1000 people, 950 people don't use drugs means they got negative in test result and 50 people use drugs means test came back positive for them.
So in these 950 people, 20% are false negatives which means those 20% people actually take drugs but in the test they came as back as "not using drugs", this is the meaning of false negative...
And I understood the part of true positives, coz in 50 people 90% people do actually take drugs but the other 10% are false positives, which means those 10% people don't take drugs but they falsely came as positive in the test, so 45 people are true positives and 190 people are false negatives...
In total, 235 people do take drugs.
Am I right? Please correct me, if I'm wrong.
Amazing video 🤠
Thank you 😊
Thanks
