Visualization of Quantum Physics (Quantum Mechanics)

This video visually demonstrates some basic quantum physics concepts using the simple case of a free particle.

The mathematics involved was taken from this excellent book:

That click is the most satisfying sound I've ever heard.

A physics student is pulled over by a cop who asks him "Do you know how fast you were going?!" The student replies "No, but I know EXACTLY where I am!"

Remarkable. So the more massive an object (compared to an electron), the less of an effect uncertainty has. So when you get to the macroscopic level, it's a concept completely foreign to an observer. This is why Newtonian physics is such a natural conclusion, because quantum effects are so negligible at our level.

Been reading books about quantum mechanics for years, and I've never completely understood nor could I tie everything together, this video explained things SO well, I almost cried. Awesome video.

The final part of the video visualized well how uncertainty decreases exponentially as you approach macroscopic scales. It's at this point where classical physics becomes a very good approximation.

As a physicist I have to thank you for making this video. Simulations like these are more tangible and easier to digest for younger minds. Your effort is greatly appreciated.

This is exactly what Youtube needed. tired of all the metaphor in explaining quantum physics, this comes straight from the horse's mouth, with the horse being mathematics.

I honestly don't think I've ever seen a more complete, accurate, and easily to understand visualization of such a complex subject (or at least, what others have made it out to be) in my life. Amazing. If only all subjects (computer science here) could be so perfectly visualized. I've never before realized how truly important it is to have an explanation of complex material/subjects be explained and visualized in an understanding way and how much you can learn based off this sort of material. I wish my professors could explain these subjects like this as a background, and THEN delve into the complexities. We'd all be better off for it, and I think learn much more in the end.

Whilst I'm not a fan of skipping over equations, derivations and insights from pure maths, quantum mechanics is a vast, complex, in depth subject, and is usually bogged down in mathematics, so it is often highly misunderstood by alot of people (to the dismay of the average person who wants to learn about the laws if physics, not the law of attraction).

This video makes the key concepts of quantum mechanics (uncertainty, fourier transforms, wavefunctions, position and momentum bases, measurement, collapse, and the classical limit) very easy to understand conceptually, and it is also very accurate and concise. It doesn't bring up interpretations, spend 10 minutes despairing about the measurement problem, EPR or philosophy, and also doesn't throw 300 equations at you wihout explanation (school systems take note).

Overall a really good video for anyone who wants to get unto quantum mechanics.

First time I've ever actually managed to understand an explanation of quantum physics. With how everything was worded, I was actually able to intuit things ahead of time, and that pleases me more than I can describe. Thank you for this wonderful video.

[Mr.FranciscodeMiranda]

I think the reason why this video explains things so well's because of the visualization factor. In college, every time I didn't understand something (especially when it came to math) I'd ask the teacher to give me an example by drawing a graphic. It really helped a lot and made me think that not doing so is a big part of why mathematics, physics and other matters alike seem more difficult than what they really are

[samieb]

So glad there aren't stupid metaphors like in every other quantum mechanics video

[NuclearCraftMod]

Showing how the wave function evolves after the position measurement was incredibly impressive - fantastic job!

Richard clearly didn't read the Youtube comment section.

[Ignis]

I was assigned a high school chemistry paper on the development of the atomic model (and quantum theory), so I chose to write on the uncertainty principle. I never properly understood it until I saw this video. Total legend.

[Huntracony]

I understand why this video took so long to make. Thanks, this taught me a lot.

[Zoxeful]

yeb Einstein was right, time is relative: 15 minutes on youtube = 15 hours in school

[MortezaVafadar]

I am a Physics student. This video was incredibly helpful. I will watch it several times again to embed all the visualization in my mind for further use. Thank you so much. This video exactly fulfilled what I lake for several years.Truly appreciate it.

[gabrielb.]

So, in the end, you brought quantum mechanics back to our ordinary classic world. I'm... AMAZED

This is some high quality, premium CG Animation. Bloody amazing work!
