Do you have variational methods anywhere on you channels? Tried looking for them, but not sure if they even exist...

Better than thousands of videos

They won't tell you that,This force, cause,s all life to pop in and out of Existence Why won't they tell you?😮😮😮😮

What's wrong is there is no positive and negative its one chain, I see all.🎉and One Power Luke Skywalker 🍯🗣️🌬️💨

i understand that the wave function is a complex number. But may I ask why the function must be in complex? instead of being simply cos(kx-wt)? many thx

DrPhysics, i thank you for these lectures from India

20:18 why K is taken negative?

Excellent explanation!

Just say because it's changing direction, it is changing velocity and therefore accelerating... such an easier way to explain it.

Thank you. I am in the middle of reading A brief history of time which mentioned Feynman’s sum of histories..which you indeed explained superbly 😊

If he started later in KZbin, might have attained even more subscribers.

You are perfect

Unfortunately you mix units and symbols all together. But great video! Symbol: V = E / q (voltage) Units: V = J / C (units)

Einstein once said "there are some things that are simple, but are hard to compute". Looks like one of those. PS. If I (as PhD) fail to follow the reasoning - this is not Einstein's issue. This is the issue of my mental capabiliries. Go, science, go. Pps. This looks like "just learn and use the trigonometry". Well, I failed to learn trig.

God of physics🎉🎉🎉

ChatGPT recommended me this channel and it's so good 😍❤️

thanks i have no word to thank you. i was bit confused about the given topic but i feel so relaxed now. you taught me well.

How much electron volts [EV] is n=1 for the other chemical chemical elements (118 from periodic table)?

THANK YOU! 😭😭

very nice video! helped me tremendously

I want someone in my life as reliable as whatever he is writing with.

🎉🎉🎉🎉🎉🎉

As a professor of physics, I can just say that there is excellent teaching going on here. Hat off.

Wow at last I found the way to put every puzzles that i had learnt together. Thank you

7:21 the answer of the question that you emphasized is u = - 2.3m/s , s = 1.27 meter ?

who is come in 2024😢

But long before the singularity only theoretically by extrapolation can occur all matter and atoms would undergo fusion and fission and be transformed to pure energy. This enrgy,all of it, would evapourate away from the evr increasing density thereby slowing the contraction and prevent the creation of the threshold. Therefore a Black Holes are merely figments of human mathematical imagination and cannot nor do not exist in reality. They are only hobbies of mathematical physics which garner prizes and funding for otherwise impractical physicists.

It's also possible that because of this intensity equation that if a star is far enough away the light may never reach us if it is truly infinitely far away from us. Especially with that silly radiation wall we observe through our telescopes; which I believe may just be technical limitations on our system, and is akin to the draw distance on video games. Potentially providing proof we are all in a simulation.

! Wow!

Really appreciated ❤❤

This is my summary of the video Psi가 e^ i(kx-wt) 꼴임을 전제(이전 영상 참고). 1)dPsi/dx = ik Psi d^2 Psi / dx^2 = - (p^2 / k^2) Psi E, p, U 관계를 통해 TISE 유도 2)dPsi/dt = -iwPsi EPsi = h바/(-i) dPsi/dt TISE의 EPSI항에 대입하여 TDSE 유도. Comparision with general physics textbook: - SE is given - solve with **seperation of variables** - get phi = e^ -iEt/h and psi follows TDSE and Psi = psi * phi - general solution is sum of c_n Psi_n

please can you talk about dimension

Very nicely made!

Difficult but well explained thank you😊

@DrPhysicsA - Great Video! You do an excellent job of explaining things. You are very clear and easy to follow. I'm learning a lot and have been taking notes. I'm about half way through the video (and I want my notes to be accurate), but I do have one question: at about 1:02:05 you say that the double differential is represented by capital gamma; however, at about 1:03:25, you add that value to your partial of V with respect to y. It seems to me that value should be subtracted. Can you please help me understand if I am missing something? I appreciate your video & your efforts!

Man! U r the guy who taught so well through ur videos tht i was able to pass Alevel physics with out any other teacher! Although i got a D but i wanna say thanks!

-i is not come from how u solve it in the end....it must be +i as you show it in your solution

Thanku so much for explaining it really help me in radiology subject

10:08 “newton’s theorem”?? i think 🤔 gauss’s theorem 😊

Dr Physics and Jason ( Maths and Science) are the best teachers.

I found this channel a few days ago! It’s brilliant👍🏻👍🏻👍🏻

I saw another video where the teacher put the resistors and the LEDs on the other side of the transistors (so between the +5v and the transistors) does it work the same?

This was the best explanation I have seen yet!

Thanks Dr Physics 👍

But doesn’t that just show that the wave function solves the SE? Could’ve just plugged it in.

Brilliant- this simple analysis cuts through all the other confusing analogies and I FINALLY understand it! (Although, of course, I don't understand the true, quantum nature of those darned photons!)

After many other videos, with this one I could follow till the end. Is there any chance to develop the 0.25 result in case of "true entanglement" in a similar way, or is it only based on experiments?

1:16 “space in itself is expanding” you don’t know that.
