Use another symbol for omega this is not used here

0:15 This is a bit more complicated. In the beginning, the ball may yet be above / right on the surface, and we already apply a large force to it. Yet the buoyant force is still zero, because there is no submerged volume.

2:47 Water is not compressible.

1:46 I doubt that there exists a purely gravitational way to explain why the block rests on the table.

Why is quantum mechanics so interesting. Deals with all types of wave phenomenon and the corresponding theory behind. Mostly foundational structure or structural foundation.

Loved this video. I'm reading The Theoretical Minimum Book 3 and this video was so helpful in tying all the concepts together. Did you (Elliot) ever end up making the video linking the electromagnetic potential to the electric and magnetic fields?

Very well explained. However, I didn't quite get the final conclusion. If the equation applies to circles, ellipses, parabolas and hyperbolas, why are the planets orbiting in ellipses? He mentioned the angular speed, but can someone explain it further? I think I didn't get the "that's why earth is orbiting in ellipses".

this is the only clear explanation of the math I’ve ever heard in such a short clip. Awesome visuals, great narration

physics and mathematics is my passion , thank you for ligthing my mind , see you in future

6:12 there is sin(nx/R) not isin(nx/R)

There is a mistake at 6:45

buen video, desde Tulio

This is amazing mate, one of the best and simplest ways to introduce such a complex topic. Cheers!

Surprisingly, this was in our exam back then. I was the only one able to answer correctly, means I have 1 point higher than everyone else in the room making me the top scorer. It's about density, mass, volume and water displacement. Not the expanding of the gaps of the atoms when liquified. Also, the sea is composed of salt not freshwater.

To make the change of variables u = iv rigorous, I think one has to consider contour integrals. As an alternative, I recently solved a similar integral (int sqrt(x^2 + 1)) using the identity sinh^2 + 1 = cosh^2. Please note that T(x) should point "in the same direction as" T(x + dx). In total, you managed with only one mistake, which makes this frankly the best physics video I ever watched, including many by distinguished professors.

Can you do the symplectic basis regarding this topics like simplectic involution

Thank you for the video.

It's amazing what you can do with "the integral of zero is zero"!

Please make videos for quantum & the spin details as you said

the dx at 0:12 is horrifying

Brilliant. Have been looking for such mathematical explanation!

Thanks Elliot, for explaining the Principle of Least Action by using Quantum Mechanics, that last part of the video was so important for visualising all the math you did before. I’m actually mind blown. Now I have a better understanding how the epsilon proof before manifests in actual physics, because before all I could see is formulas and kinda had to accept it to be true. But you actually did it. HUGE thanks, subbed today!

Real life method: numerical integration

Until today I thought F=ma (though as F=dp/dt) was the most fundamental thing in physics, and was very concerned that quantum mechanics' blurriness seemed like it would be in violation. Interesting to learn how it can be derived from the Principle of Least Action which shows up in all the theories.

Absolutely wonderful video! Can anyone explain why the tension forces at 4:20 have to be tangential to the curve? I don’t understand completely.

I wonder what would be the the resulting pattern in double slit experiment if we vary the depth of the slit 🤔

There's a physical motivation for why the Lagrangian is T - V. And that is its representing the transfer of potential to kinetic energy, an action (pun intended) that occurs in every classical motion

Thanks for your interesting video. Area under a curve is often equivalent to energy. Buckling of an otherwise flat field shows a very rapid growth of this area to a point. If my model applies, it may show how the universe’s energy naturally developed from the inherent behavior of fields. Your subscribers might want to see this 1:29 minutes video showing under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Containing the column must come in to play before over buckling, or the effect will not work. The sheet of elastic material “system”response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( ie peeks and troughs) of the fields “sheet” produced a stable structure when the undulations are bonded to a flat sheet that is placed above and below the core material. Some say this model is no different than plucking guitar strings. You can not make structures with vibrating guitar strings or harmonic oscillators. ruclips.net/video/wrBsqiE0vG4/видео.htmlsi=waT8lY2iX-wJdjO3 At this time in my research, I have been trying to describe the “U” shape formed that is produced before phase change. In the model, “U” shape waves are produced as the loading increases and just before the wave-like function shifts to the next higher energy level. Over-lapping all frequencies together using Fournier Transforms, can produce a “U” shape or square wave form. Wondering if Feynman Path Integrals for all possible wave functions could be applicable here too? If this model has merit, seeing the sawtooth load verse deflection graph produced could give some real insight in what happened during the quantum jumps between energy levels. The mechanical description and white paper that goes with the video can be found on my LinkedIn and RUclips pages. You can reproduce my results using a sheet of Mylar* ( the clear plastic found in some school essay folders. Seeing it first hand is worth the effort!

Watching this I realize I have much in common with the Scarecrow from the Wizard of Oz .

no start by diffraction

This was one of the most beautiful things I’ve ever seen 😭💯

I'm graduate student and really enjoying your series nowadays :) If I would go back to the past, I'd say myself watch yours.

So this is how a physicist wield calculus...

NOT German. Her German citizenship was revoked because she was Jewish. She was refused employment by Harvard because they did not allow FEMALE professors. She was hired by the famed Smith college. This is the MOST IMPORTANT THEOREM in all of Mathematical Physics.

I hope it's fine to use the link to this in an answer on Quora. Thanks in anticipation

Thank you!!! I was just thinking about this kind of tutorial!! I learned that Uranus was discovered through mathematics before it was located visually and I wondered how. How did the math look? There’s others too. For example, Kepler realized the orbits were elliptical… how? How, by only looking trough a telescope were they able to figure out the precession of Mercury? I was thinking if I had enough money someday I would pay a physics instructor to make a tutorial about those things. This is a step in the right direction. Thanks for this!

Best posbl explanation of GR

I'm a negative zero of me learning this

I wish you taught me how physics work.

It's funny how I just want to know the basic formulas for physics and now I'm learning this 😂. I had a calculus class but we were unfortunately unable to get to the taylor's series because of how hard it got. If our teacher wasn't as kind and nice to us, we will surely be learning this. Anyways thanks for the video!

Bro, just wanted to say keep this up. Clearly I'm not the only person who holds this opinion, but the way you teach by working up from the foundations to build the intuition behind these ideas is great. Speaking as a non-traditional physics enthusiast who is learning this as an adult, the pedagogical approach is wonderful.

One of the Best mathematician.

ive always loved math. my dad taught me to love math as a chore but he didnt expect me to internalize it, for some reason. i asked him why, he said that "it'll be useful for understanding higher physics when you prep for difficult exams concerning physics and maths". i never understood his logic until now. i feel like i can love physics the same way i do maths, for the first time. im grateful for this channel. thank you. such an incredible little gem. and thanks dad. you know next to nothing about science but simultaneously know everything. because true science is just writing stuff down for later, not knowing what it truly means.

The position and momentum can be determined simultaneously Attosecond spectroscopy debunked the Heisenberg uncertainty principle It was used to observe the motion of the electron applying electrodynamics and attosecond spectroscopy

Okay.

amazing!

I love the video. Very useful and easy to grasp

The magnetic force is the issue; it is a type of relative force, unlike the electrostatic force. Stop the motion of the charge and there is no magnetic force.
