  • What physics related questions are people asking on Google? Why not ask a physicist?
    Hey guys, I'm back with a bit more of a chilled out, sit down and chat, style video. In this one, I'm searching the most asked questions on Google regarding physics and physicists, and answering those to the best of my ability for you. I made this video as a little commemoration of the fact that we have hit 8000 subscribers on this channel!! WHAT!
    Now some of the questions I answer in this video are: Why do physicists hate engineers? Why do physicists hate chemists? Do physicists make a lot of money? Why is physics so boring? Why is physics so interesting? Why is physics important? Why do physicists use models?
    So if you're interested to know the answer to any one of these questions, then watch on! I also asked my Weekly Question of the Week, which this time involves getting an opinion from you guys. Basically, some of you might have seen the video where I analyse the world of Harry Potter using physics techniques. If you haven't seen it already, then check it out here: • Video
    My question to you is: what other fictional universes would you like me to try and analyse in the same fashion? Let me know in the comments down below.
    Also, for those of you that used to enjoy my vlogs back in the day, when I was vlogging my uni life, guess what? I've started vlogging again! This time it's on IGTV though, so follow me on Instagram @parthvlogs.
    See you soon!

    My dad told me a joke and I thought of this vid.
    There's a Mathematician, a Physicist, and an Engineer. All are tasked with finding out how tall a tower is. The Mathematician gets straight to work. He waits until 12:00 and measures the length of the towers shadow and angle of the sun, then uses trig to find the opposite length.
    The physicist realized he doesnt need a clear sunny sky and he climbs to the top of the tower with an apple and a stop watch. He measures how long it takes the apple to hit the floor and derives how far the apple travelled. The Engineer looks at his two friends going about their business bemusedly. He picks up his phone and asks the Architect how tall his tower is!

    As an engineer that had some introductory physics courses later, I realized engineers often use a simplified view on physics because they’re constantly under pressure to get something actually working. Very often managers don’t care if engineers truly understand what they’re doing in a scientific way, as long as they produce results. Personally I came to the conclusion that everything is about physics, even chemistry.

      Yes physics make You understand why your stuff works. But You use that for build something. I wonder if a physic can make something using his knowledge. For example an industrial machine for make something. You need to know mecánic, electrónics, some sort of electromecánic. Not for study all the components separately but to know how to make it works.

      Engineers make fun of physicists, too.
      True story: On Halloween my Digital Signal Processing prof walked in wearing a hunchback costume, along with his wife and two kids. They galloped around the room and passed out candy, then mom and kids left. Dad then proceeds to take off his hunchback costume because it's uncomfy and he's left wearing a t-shirt. He asks "so what character am I now?" Silence "A PHYSICS PROFESSOR!" ba dum Ching
      See, engineering faculty tended to dress pretty well. Some wore suits every day, most just settled on slacks and a nice shirt, maybe a sport coat at most. Math and Physics faculty were more likely to show up in shorts, sandals with socks, and a 25-year-old tshirt with 6 holes in it.
      I worked for years in the Math+Physics building doing computer stuff and had a lot of Physics faculty friends. IRL they didn't really make fun of engineers and, in fact, often asked for help on stuff too far outside their bailiwick. A lot of "hey, you're an electrical engineer, would it be possible to build something that would...".

    Physics was traditionally a subcategory of philosophy, which took advantage of mathematical principles to prove its theories. Before the 20th Century physics was referred to as natural philosophy. If you're looking for purity, philosophy and math would be the place to go, not just math.

      @no u trash I can understand why you think that, a lot of people do, and a lot of academics in most fields are draconian in the sense that they just teach the 'old stuff', but you need a foundation in order to have a full appreciation of the 'new stuff'. Trying to understand Einstein, without Newton, without Galileo is possible but your understanding will be more difficult and less deep. Same with Philosophy, trying to understand Frege or Russell, without Kant, and further back Aristotle, or Plato is superficial. That being said, critical thought is timeless, in a sense it doesn't matter when it was written as long as it is correct, in another sense it does matter because certain trains of thought are more or less likely to arise given the changing nature of circumstance.

    • @benjanes3675
      @benjanes3675 3 роки тому

      Also, even the newer authors I just spoke of, like Einstein and Russell have a new generation of academics responding to their philosophy and math, so in a sense they are becoming 'old', too.

      I got friendly and hung out a lot with a new Visiting Asst Professor of Physics because I did computer stuff and he used super computer computer stuff and we were in the same building, separated by two floors. He was woefully underpaid. But what I determined is newly minted just-past post-doc single physicists eat absolutely anything as long as it is on sale and can be eaten without any preparation. His favorite: the $4.99 all-you-can-eat spaghetti at the little restaurant a block off campus. Like... 5 nights a week. I'd give in and go with him (too) often, but it was really awful. Not sure how you screw up spaghetti that badly, but they did it.

      Hello simal linjara don't that I am intervening this conversation between you and the man who made the video I think you have not watched what he has told their family actually the problem of smoothness function of navier Stokes equations has to be proved by mathematician's in order that physicist or any engineer could take care and use it so please wait still the mathematician prove the theorem so that is what physicist make fun of engineers and mathematician's make fun of physicist and even philosophers make fun of mathematician and I make fun of you all guys simply kidding yaar don't be angry at meyes please go and watch the millennium problem now you'll understand why turbulent flow around any floating or flying body is so difficult ok aur please read the below statement I made
      Physicist think they are limitless that is the basic problem that physicist think there are so mighty ok for some reading this comment maybe maybe not comfortable because physicist is trying to fit the model by observationok please explain us can somebody ask here are the three examples I can give you
      1.) So physics has this quantum mechanics as there more powerful tool to understand the world now you have this .atoms and subatomic particles and still in search of some atomic particles they think it could explain everything about the world and even it could explain consciousness because they consider atom as and indivisible aur cannot break in normal sense so what happens is the try to fit the model of chemistry biology and and everything but still mathematician's even have this "atoms in the subject Mathematics that's crazy "how mathematician's can have atoms in mathematics yes atoms of mathematics are prime numbers and mathematics have their acceptance of human failure to acquire the whole concept of primes because you cannot factor number beyond primes and every man greedy starts from here to mathematician century give the framework for the subject infusions used to use it ok now what's the point the point is logic has this atoms called axioms and axioms are unacceptedbut believed to be truth and some theorems are being proved by it
      But mathematician's also have this limitations that has godel suggested that no axiomatic system could explain the concept of or could explained every part of the mathematics so Godel give the limitations of mathematics in his proof on incompleteness theorem and physician things still there mighty and these kind of proofs build by mathematician's instill physics Gets every framework from mathematics and think they have no limits and even the subject has no limit such as mathematics but physicist think there is a chance there just waiting for a chance to somebody give the frameworkso that the problem starts there is also this so called of logical way of proving in physics but it is only to those who require higher knowledge on this physics the missing parts that as in our discussion world is made made up of atoms and atoms govern every law in the universe and frames are the basic to mathematics and still mathematician's find very difficult to say how many primes are there within n numbers but still physicist are very convinced that there will be some mathematical framework that is going to help them resolve this quantum gravity show the basic idea is that has to have a component of basic structure which is indivisible and it has to form the whole part is so logic atoms are not well defined that is the framework of axioms if we go higher than logic there is philosophy nobody can tell that philosophy has atoms inside going above will be consciousness I don't think every part of our thoughts is made by some indivisible small part this theory could not be explained in mathematics because "apart is never greater than the whole" so this is my concept if somebody could answer me please answer me because I have searching for this answer for a lot time I Ho Mr part g gives good answer to this and don't please make mistake of thisbecause between the layer of philosophy and consciousness I have missed the most important part foursome it maybe ideology or religionso sorry for that so even you have this God concept in religion which makes up everything show the concept of making something indivisible or an individual part cannot be explained by this and and and theory has to have its limitations which should be proposed by the knowledgeable that's why most of the theories in physics don't come in to use because it is not that it is under research because some fieles their limitations as this concept of galios proof on symbolism breakdown in polynomial root calculations where it doesn't have any routes that can be framed by its coeeficients and the whole concept of symbolism is like that and still these people are relying on the other framework of deep learningand other neural networks still have not been till proved to be symbolic in nature and they think they need just an turnacation point p on this value but the symbolic nature is very different it could only say the limitations and even it has its own limitations so just figure out the limits of your subject then please tell your mightyness I hope the man who made this video will answer thisand I still hope somebody good answer my question if I am wrong I really bow and accept comments but please don't brainwash Me if you think my facts are very little and I have this krunger effect please flood me with factsare just you people think I am feeling you with facts give proofs anyhow you can just open by reading the comment and open my third eye of knowledge so that everybody will be benefited

Engineers need to account for social. environmental and economic factors, and all the uncertainties in the real world. also the big brother and little brother analogy is just awful, yes your right physicist gives engineers knowledge to build things, but engineers then build things for physicist to continue their studies. It is much more of a feedback loop.

    Physics and engineering and male dominated because the most introverted people are generally the ones that find them more appealing. Both are focused more on the world than on people. Males on average are slightly more introverted than females. Selecting for the extreme ends of the spectrum greatly exaggerates that tendency. Imagine two overlapping bell curve distributions of people based on how introverted they are. One for males and one for females. Introversion is increasing as you move to the right. The female one is shifted slightly to the left of the male one. If you chop off the right side of this diagram (the people who become physicist and engineers), you get overwhelmingly males.

    The "dark matter" arguments are based on stars at the edge of the galaxy not spinning off into the void. The claim is: there must be extra mass in the galaxy, holding planets in place.
    But - what if, on large scales, space simply repels mass? That is, the void between galaxies is pushing stars back toward the middle?

    "Why do physicists use models" (or any scientist really) is a bit of a difficult question to answer directly because it implies a lack of understanding about what a model is. Its kind of like asking "why do cars have wheels?" A bit of a patronizing first answer might be "because it wouldn't be a car without them!", and to a first approximation that kind of is the same thing. "Why does science use models?" "Because it wouldn't be science without them!" We could be a little less patronizing with something like "they're a tool to describe the world mathematically". That's a bit better but its still pretty vague and still only really answers "what" more than "why."
    But everyone seems to understand money, so let's try to build an extremely simplified example model by way of money, and hopefully through example show why the model is a useful tool. I'm sure I'll make a mess of this but why not :D!
    Lets say you have a bank account with $100 in it. Well right off the bat, "$100" is a model. That's not a physical object, its just 4 characters that we all generally agree represents some amount of (real) wealth. OK good. We know what a model is!
    But wait.. that model is pretty weak. If you withdraw $30, your model is now completely broken. It only encompasses your bank account having $100 in it. So we need to make it more complicated: our bank account can now be represented by "a member of the set {$70,$100}". But that's not very useful really. We really need to know that the $70 comes after the $100 so a concept of linear time should be introduced: "$100 first then $70".
    Better, but that's still pretty limiting. We might want to make a further withdrawal tomorrow and the next day and so on. We're getting pretty cumbersome. So lets introduce some notation: "B(t)=x where (t,x) are members of the set {(1,$100), (2,$70)}" In fact, notation is so helpful that I've already introduced some that you may not have even realized: I used set notation briefly above before introducing time. But that one might have been a bit obvious, especially if you aren't familiar with set theory. But how about "100"? That's also a notation. We could have represented your bank account by 100 individual tick marks or "0x64" (hexadecimal) or "C" (Roman numeral) or any other system of humanity has ever come up with. But the decimal number system is such a convenient and widely-recognized notation that we've been making use of the concept without even realizing.
    But back to your bank account. Our model is now at the point where we've got a very simple equation B(t)=x, along with a table of possible values for t and x to take on. This is actually already sufficient to model one very basic function of banking: Your monthly balance. If you ignore the rest of your bank statements and only focus on the month number and the total, our "model" is sufficient for you. You of course keep having to manually add entries to the table every month, but it does the job.
    We're still missing something pretty important though: dynamics. We can see that our bank account dropped from $100 to $70 in our model, and we know that its because we withdrew $30, but the model currently has no concept of what a "withdrawal" is - it just shows two points in time with two different dollar amounts. So how do we model a withdrawal? Well for that, we use operators. You're familiar with some very basic operators already - addition, subtraction, multiplication, etc. The operators used in physics are absurdly more complicated than those, but the underlying principle is the same: its something that can be applied to a set of values to produce a new value. So what might our withdrawal operator look like? Possibly something like: "W(B)=B-$30".
    Wait.. that seems a little weird. We're passing B into W? More notation there - typically if a function is passed to another function without its parameters, it means "do the same thing no matter what the parameters are". So in this case W(B(1))=W($100)=$70. But wait again.. that would also mean W(B(2))=W($70)=$40. That's not right. We never said we withdrew another $30. Luckily we're so far only using this operator to calculate withdrawals and haven't updated our bank's table, but its still pretty unsatisfying. We can do better: "W(t,B)=B(t)-w if (t,w) is a member of the set {(1,$-30)} and W(t,B)=B(t) otherwise". Now we can do something really fancy: we can redefine "B(t)=$100 if t=1 and B(t)=W(t-1,B(t-1)) if t>1". Suddenly our bank account table is automatically "updated" any time we add an entry to our withdrawal table. B(t) is now incorporates some (trivial) dynamics!
    And of course we can keep extending our model to incorporate deposits, interest, bank fees, etc, etc. When we notice a "symmetry" we can simplify our model (for example, deposits are "symmetric" to withdrawals, and in fact the way I've defined the W function already handles both just by using positive or negative numbers in the table). We can extend it to use arbitrary timesteps - right now it only works in fixed-interval discrete steps. You could choose any step size - an hour or a month or a year - but you can't have one entry be an hour and the next one be a year in the same model. Of course what you _could_ do is choose a really small step size - say a microsecond - beyond which you don't expect any operations to be able to occur, and just have a really really big table.. and then if you take the limit of smaller and smaller timesteps until you hit a step size of zero, you get continuous time which adds a whole new layer of complexity and often weird infinities and so on).
    But this is already long so I'll stop with that. Hopefully anyone still reading comments on a year-and-a-half-old video will get at least a basic idea of what a model is from it :D, and in turn get a better understanding of why scientists use them.
    Edit: One thing I always like to clarify and didn't here: A model only _describes_ the world. It doesn't tell the world what to do. We can use some types of models to _predict_ what the world will do, but the world (and the universe more generally) is perfectly free to do something completely different, and its up to us to fix the model. But that doesn't mean the model was "wrong". It just means it was incomplete. This is a misunderstanding we see a lot in terms of climate change modeling - people think that if a model isn't 100% right that it might be 100% wrong. Now certainly a good deal of that is simply propaganda but the mindset is pretty prevalent nonetheless, and its simply not true. Barring a complete and total meltdown of the scientific method, a model that isn't 100% right is often 90-99% right and just needs tweaking rather than a complete rebuild. (Of course complete failures _have_ occurred in the past - for example the theory of the luminiferous ether that was disproven by the Michelson-Morley experiment and caused a relatively large upset in the physics community of the time. But such massive failures are extremely rare in the age of the modern scientific method. Won't say another can't happen - looking at you, String Theory - but its not the conclusion you should jump to when you see a climate model being off by 15 knots predicting a hurricane's force or something.)

      ThatGuy I did the same except switch fm for biology. I got 4A* and am off to Cambridge to study Natsci (like Parth :) )I would say the biggest thing is to prioritise understanding concepts over anything - learning like this makes it so that the volume of content you need to actively remember is vastly reduced as you can derive it from understanding - also this way application questions become a whole lot easier as you have a much deeper understanding. Secondly use active recall (watch Ali Abdaal vid). Lastly, I would recommend working hard in year 12 so in year 13 you have plenty of time to dedicate to entrance tests, interviews etc. etc.

    A moving rod placed in a stationary U-shaped frame.
    When a conductor (the moving rod in this case) moves perpendicular to a magnetic field, an electromotive force (EMF) is induced according to Faraday's law of electromagnetic induction. The rate of change of magnetic flux through the loop formed by the moving rod and the stationary U-shaped rods is given by = B⋅L⋅V where B is the magnetic field strength,L is the length of the rod, and v is its velocity.
    Now, the negative of rate of change of magnetic flux = work done by electromagnetic force throughout the loop, which is BLV+IR, i=current , r=resistance
    But this leads to that,BLV=BLV+I--->>IR=0 , means electric current through loop is 0, So, Just Please Clarify My Confusion

How do you tell a mathematician from a physicist from an engineer? A. Ask them to prove that all odd numbers are prime. The mathematician says “1 is prime, 3 is prime, 5 is prime, 7 is prime, and the rest follows by induction.” The physicist says, “1, 3, 5, and 7 are prime, 9 is experimental error, 11 and 13 are prime, and the rest follows by induction.” The engineer says, “1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is prime, and the rest follows by induction.”
