Thank you:)
I'm 51 years old, I dropped out of high school and got in to drugs and played drums in rock bands in 1989. I wish I had of stayed in school on got the education when I had the chance.
I spend my free time these days, reading, learning Algebra, physics, chemistry, and biology......
The feeling of regret can be very powerful.
Mathmatics welcomes all that will listen.
@@83jbbentley Great quote Love it !!!
It not too late to self study physics 1-3, calculus, linear algebra and differential equations
To be honest, even if you had tried to stay in school without a passion for learning, it wouldn't have made any differences. And I can't say for you, but where I come from (an asian country), the education system is such that it is not really about learning any more. The exams are unrealistically difficult, and everything is made like a competition where everybody is trying to get to the top schools just for the sake of it. As it goes on, many of us lost the curiosity, the genuine passion to learn and acquire knowledge. I've seen many people (myself included lol) graduating high school, college or university with a degree, yet seem to forget most of the basic fundamental knowledges of sciences that are taught in our earlier years.
The most important thing is: You are motivated to learn Right Now, and that is all that matters 🔥❤
Thanks math sorcerer, love the message about only being in the class once. As a college student, whenever I feel unmotivated to study for a test I always tell myself that this is the only time I'll ever take that test in my life. Anticipating the regret that I would feel if I didn't study usually gives me what I need to push through!
I cannot reiterate enough what you said, you really do have to practice-practice-practice everyday or almost everyday, but it gets better and is worth the effort. As someone who spends 3-6 hours a day doing physics material from homework to studying, re-doing the same problem I just couldn't quiet get until I got it and using up my professor's office hours after nearly every class (bless my professor for being so kind and patient) it truly is better to do it, like coding or muscle memory. Solving the complex problems with critical thinking takes time to develop the skills and comfortably with them.
Always remember the laws are your guide for the math to follow, diagrams and assumptions are important to draw out and list. If you make a mistake it's easier to see where your train of thought was leading you and where it went wrong. If you can get to a final expression based on the laws then it can be said you understand the physics. The diagrams you create will help you understand the laws at play and what to apply, what forces are where, which direction things work in and they're a great visual aid in problem solving. If you don't know where to begin it's okay to find similar problems or crack open a book/pdf, but start with setting up your diagram. (I originally wanted to be an artist but my family didn't come here for that apparently lol this is my 3rd degree in physical sciences (Atmospheric Physics for this one) and the diagrams are my way of letting that inner child's dream live on).
BOOKS are very helpful, but they're meaningless if you do not apply them, other than the recommended Giancoli book, there is also University Physics With Modern Physics by Young and Freedman, which covers everything from the mechanics, heat, sound course, to Electricity and Magnetism, Light and Optics, and Nuclear, Particle and intro Quantum mechanics. A free series that is well loved by every professor I have had since it is easier on students wallets is the OpenStax University Physics Volumes 1-3, they are free online for anyone and cover the same material.
Cannot stress the importance of math enough, algebra, trigonometry, Calculus (especially integrals, differentials, trigonometric substitution), and everything you can learn with vectors. Its a gradual process and no one is born knowing these things, but with practice and dedication it gets better with time. Just never give up!
If it's a hard problem to solve then it's a good problem, don't be afraid to ask for help or step away to clear your mind. Usually tests are the most important factor for your grade, just try to improve on them each time little by little and focus your study and time for what is weighed the most (i.e. tests) every professor has different formats and expectations so recognizing them as early as you can will benefit you. If you want to learn and are interested in learning then you should come to find most teachers won't stop you from trying to do so, just keep at it.
P.S. Partial credit cannot be given if you don't try, and teachers/aids will be more patient and willing to help if you've at least tried yourself first.
Great motivator for almost any subject in college or your life after college. Find your reason to take physics or any subject if you have a humanities or liberal arts background. Even in retirement:)
Thank you, this is such a helpful comment!
I am currently learning physics right now. The math for me is actually really simple given I know Calculus, Linear Algebra, and ODEs. But conceptually understanding the physics has been really hard for me.
It’s like you can’t simply brute force the math but instead have to step back and look at what is qualitatively going on. Like if an object is being thrown upwards you can always tell that it’s vertical velocity is zero at its highest point in the air. If if the problem says ‘from rest’ then initial velocity is zero.
If you think about it, science and maths are the magic in our world. Understanding and using the workings of reality. It is very much like magic.
I'm a high school student and I need to learn mechanical physics and what i'm going to do is solving one problem every day.
If you need motivation, look up Feynman's lost lectures. He is awesome.
Can you do a video on retention? I have asked a few times already. As a student, my biggest fear is forgetting stuff. An example would be applying differential equations in my dynamics class. How do you best deal with forgetting concepts.
I want to share my reason. I understood Calculus and differential equations after I studied Physics. It makes sense because Newton is one of the two people who came up with Calculus.
The ability to sit down and do what you have to do is something you need in everything. I’m in high school and I’m learning ancient greek (I don’t live in the US) and I had the luck that I really like it, so it’s easy for me even if I don’t study much, but for most people it’s hard; well, what did our teacher tell them? “Do a little bit of greek everyday, at least half a hour a day, like maybe translate some phrases or a little part of a major text”. That’s where the point is, in all things in life, you have to put the work, maybe less than others cause you’re the lucky guy who can learn much easier than others (like me for ancient greek), but still that’s what you gotta do
Physics uses math, but it is not just math.
Understanding, visualizing and drawing (doodle) a problem based on physical principles are the fundamental skills to develop a deep physical intuition. Work through examples and derivations on your own (with the book closed) at the start, and use physical arguments to drive the math.
First things first though. Learn Calculus first. (Absolutely crucial for classical physics.) Then Linear Algebra (Important for quantum physics)
The MIT lecture series on physics is really good.
Hello math sorcerer. Been doing math and physics problems whilst listening to your videos. keep up the good work .
what i like the most is that i do understand pretty much everything you say without subtitles. thank you for the great content, and for speaking clearly
If you want to appreciate and slowly savour the way the universe works, then physics will help you out. But at a cost: you need math every step of the way. My personal recommendation for a good 'survey' course for physics is Sears and Zemansky's 'University Physics With Modern Physics', and for getting into the necessary math for individual subject areas (classical mechanics; electrodynamics; thermodynamics; cosmology, etc.) then Mary Boas's 'Mathematical Methods In The Physical Sciences' is great.
Hi math sorcerer, I am grateful to have found your channel. I just did pretty poorly on my first physics quiz in my first college physics class. I am going to listen to your advice and report back, let this be an inflection point.
I love physics as someone who is going to school for engineering. Luckily I found a major at KU that is the best of both, which is engineering physics. I'll already have one degree in Engt technology and it will cost me likely 20k more in debt, but I find it to be the path for me.
I know there are different levels to physics. My sister took a regular physics class in college and it didn't have any calculus. I take ASP physics and it uses all the math I ever learned, algebra, trig, calc, stats and it's going to pressure that. I've only had to cry like 4 times so far so I think things are going okay. Professor says that's normal. I make sure I drive him crazy though. Funny story. He was teaching us about range equations and earlier in the lecture we did an example problem shooting a guy from a cannon and he wants to know where to put the net to catch him. Well, we did this example by hand and there was some sig fig rounding. Then at the end of lecture he taught us the range equations so on my own time I went back to the cannon example to see if I could use my new equations and get the same answer... and I get like 4m difference! That's 2 full humans! I can't have that... you can't tell me 2 things equal each other and then they don't. I sent him an email asking if the equations should work.. and he said they should. And I tell him get different answers and he tells me "the difference is academic." Im like, now wait a second here, Doc. I don't think you really appreciate the severity of the problem. Were about to launch a stick figure out of a cannon and 2 people are arguing over where to put the net right now. If this stick figure plows into the ground... are you going to tell the family the difference was "academic?!" They are going to be piiissed off at you, Doc. He attempted to carry out some decimals and only got it closer by 2m lol we still had a 2m difference. I'm like yeaaaaa I don't think so.. what kind of physicists would I be if I let my stick figure die in his first projectile motion problem. I still haven't been given an answer that satisfies me that these 2 are equal. Rounding error, shmounding error... I'm walking away from the problem lol It's obvious though that if I use the range equation on an exam for an answer and he didn't then we are going to get different answers... and not by a little bit. Enough of a difference that our stick figure is going to die... I feel like I'm the only one that really appreciates the severity of what is actually happening. And I'm sure he doesn't have 2 answers for his answer sheet so wtf is going on here? AS far as I'm concerned... I broke physics like my first week! Lol Force of gravity? You mean the force of god (I label my downward forces Fgod).... I promise I'm going to make this professor remember me for the rest of his days for making me cry lol
Man this was just... 😂😂
You just don't have enough math yet to make this number a better approximation of 'reality'... But I confess you got me laughing at the "Fgod" LMFAO 💀
Спасибо большое
Thx for your kind advice. It gives an incentive to invest more studying Physics..., and Math
I got hooked on physics when I was doing Newton's Laws of motion. I'm on the path of self-studying for the GRE physics and mathematics exams.
Hello,
It's finally a matter of motivation. It will always be.
Now that I think about that, I spend much more time with my students to get them motivated. I end up saying this same kind of things, like "ok you don't like that course but next year you will no more have to deal with it, just be curious, try to learn as much as you can from this course and pass it so that you can reach your goal, which is getting into the master's degree, where you most likely will have only courses you like".
Still, it's very hard to get them motivated... Any advice?
Thank you sir. I can see the parallel between math, physics and training. Saludos
You are necessary. Thanks for the video!! (hugs from Brazil)
I remember someone told me I needed to understand the physics concepts to understand the problems. I journaled after class what I learned and read conceptual books about first-year physics, like Feynman Lectures V1. During test time, I was screwed. I only did a few problems besides the homework and needed help understanding how the math connected. I went to office hours and did problem sets with the professor, and she let me go to her second Physics 1 class, and she didn't have to do that. Anyone can explain physics, but only if you can do the problems do you truly understand physics.
Like Bruce Lee said, "Bricks don't hit back'. ;]
Something I teach anyone I tutor, teach, whatever. Regardless of the subject matter. "The journey of a thousand steps, is not a race". So the hour a day rule is true. But you actually have to walk the path.
Physics is difficult to understand, not only it is the math, but it's understanding what the math means in terms of the system, understand what operations mean and how they translate into real world language...into something an engineer can understand and apply. Physics is difficult...from somebody who has a Ph.D in computational condensed matter physics and has done string theory.
I'm glad i found your channel. You've definitely inspired me to focus more on studying. I love your
upbeat positive attitude.
I want a video about studying physics from START to FINISH
Commonsense solutions and excellent advice. This guy really is interesting and helpful. 👍🙂👍🖖
Inspiring and well-grounded advice. Thanks!
Yes Giancoli is highly recommended...... Good to have your own copy....
I'm a class 12 passout and I really love physics,it seems to be difficult to understand physics but by trying hard it becomes crazy
physics allows expanded reference frame of reality as it functions
Yes! Doing rather than learning about.
You should upload a course on Number theory
Hey doc , I am a medical student, and I love physics and math so much , the question is how can I balance between my degree study and the love of math and physics
Self-study calc 2 and calc based physics 1 aka mechanic for to learn what physics is like. Get a udemy from that math socery.
Get the schaum physics for engineering and calculus. Medical students is on the left side for biology and chemistry. Physics and math lean on right side for very math challenge. Physics only need to take 1 gen chem for a semester to pass for material science.
Self study organic chem to get med class dones from chemistry courses; even so, calc 2 will be weeder courses for complex integral.
i have a physics 1 exam comeing up in a month, and i have no idea how to study for it. im still looking for the answer.
IMHO, review the notes you took in class and what you learned in Lab. Re-do the homework problems. If there's one you can't do, read the book's chapter or section related to that problem. When reading, consider copying by hand the examples. Muscle memory can help reduce the burden on the prefrontal cortex. (Truth be told, while I'm not an expert, neuroscience is an interest of mine.)
This video was very inspiring for me
Timely video for me, I spent the entire day procrastinating to study heat and mass transfer, which I don't like it, but I need to pass it to be able to continue with my engineering mayor, which I already invested years into 😅
Evening sir, your words are wise and your lectures are wiser but about the paid courses I don't know where to start cuz I am neither a engineer in math nor a wizard can you make a video or tree diagram sort of things to show a path of how to proceed in mathematics thank you
Thank you for this
Want to be good at something? Work on it. Discipline is the key. You can become amazing at anything if you never stop.
Way back in the day, I used the Nelkon & Parker text book. The Giancoli book looks solid stuff and is more current :-)
The most pragmatic advice I ever heard
Damn I wish everyone loved physics, I love physics so much!!
for the love of good please stop starring at me
I think physics only applies to the physical dimension hence the name."if you want to know the secrets of the universe think in terms of energy vibrations and frequency" -tesla, everything is connected
I hope I am not late. I have bought Mathematical Methods for Physicists by Arfken. But it just seems strange to start with power series and stuff although it has excersises and "answers". I need to learn function theory. What can you recommend? Generally and specifically. I would go for some good analysis books for mathematicians. But I know not if time would suffice.
Thank you.
I am self study physics 1; however, why is the tension and some questions after that get confusing conceptual. I like kinematic but tension and box friction got me confusion.
tks from Brazil!
thank you
To learn and know physics and to build a career in physics as a teacher or professor ... Is it a good reason for me to learn physics?
Small caveat with buying all these recommended books for self study. If you get any of these books and they only give some answers, and no solutions, how can you learn? You can try some problems until you miraculously come up with the given answer, but what about the rest? Yes, they give a few example problems. However, you have no instruction on how to solve the problems, especially the problems with no answers or solutions.
What's the best book for getting maximum number of problems in circuit analysis?
You can do it
This guy is getting to the point where I click the ‘Like’ button on his video before I watch.
In other words, I can feel myself becoming The Sorcerer’s Apprentice.
Happy Halloween.
Are you planning to give courses on Physics?
I really interested in physics i have just finished my high school but for political and living reasons i should go to a medical college instead of physics
But i still trying to study physics not every day because i am really scared to get into a math that i don’t know so my only obstacle now is which math should i get for studying physics (especially the theoretical physics) because i should put in my mind that i am not able to study all the math to get started with physics my life is not infinity i hope any one could help me about this point i will be really thankful,
Thanks for your time.
Start with trig, precalculus, calculus 1-3. Physics will intertwine with the calculus series.
The title here *feels* clickbaity to me
Physics is like a horror story but in real life.
Anybody seen nasa UA-cam channel before
The titles are becoming too much honestly
Why?
Being upset about video titles is outdated
I thought you were going to teach us something. Long ass video ending with you waving an expensive unattainable book around.
It is just me or does it feel like he "catfished" us with the guy in the thumnail?
Really, all you have to do is buy Einstein's book Relativity. Look at the train experiment. Einstein says that on the occurrence of the light, points M and M' "fallt zwar zusammen."
The English translation is, point M "naturally coincides" with point M'. This small sleight of hand causes a big problem. That is because, although the Relativity of Simultaneity defines the coincidence of points as Euclid does (and by the way, how DOES Euclid define it?), RofS does not define the "zwar" or "natural" coincidence of points.
That creates an undefined term in the argument, and so we can't move forward to SR or GR because, although the term plays a role in the argument, we cannot know what role that is.
We can drop the "zwar " but then another problem arises. RofS assumes two Cartesian coordinate systems, but if "zwar" is dropped, M and M' coincide in one Cartesian system. We have been led to a contradiction and again cannot move forward to SR or GR.
And that is where we are in physics.
