Video Description

There might be hidden dimensions in our Universe, undetectable by our senses. Why is this a deep idea? This is what we will attempt to demonstrate. // This video is not perfectly rigorous, it's rather a semi-artistic attempt to grasp a profound idea of modern physics. For instance, it mentions only the protons, neutrons, electrons, and not the quarks which are more fundamental. Also, many of the images used (such as atoms) are simply metaphorical. Nor do we mention the name of the theory (Superstrings) or the concept of vibrating strings. Etc. // The analogy of the cylinder showed in the video comes from an article published by the author 20 years ago. See p. 2 here :

Stephane and Pierre-Marc,

Thank you for a gorgeous and very professionally produced video! The core of the argument, the unification of the 2D circle and square into a 3D cylinder, that takes place in the 90 second segment starting at the 4:15 mark, is extremely well made, and constitutes a deep and fascinating metaphor of what it means to try to unify physics.

May I make a suggestion if you ever do an updated version or a follow-up? YouTube viewers are usually impatient and will click away if your video doesn't instantly grab their attention, so you may lose a lot of viewers by having a full 30 seconds of pretty images without words at the beginning, and by waiting a full 2 minutes and 30 seconds before really stating the main idea of the video (the possibility of a multidimensional super-particle). The current cut of your video might be better suited to the slow pace of broadcast TV. On the other hand, what do I know? Maybe you have invented a new style of YouTube science video, which is a mix of hard science and idyllic nature scenes. It is true that when you have such beautiful footage of nature, it must be very hard to make cuts! (On the other hand, generic stock footage like the "World News Tonight" background at the 3:33 mark could probably be eliminated without losing anything...)

Congratulations, your video deserves to do well in this contest. Best of luck!


P.S. If you have a chance to view, comment and vote on my trilogy of videos entitled "This Is Physics" --- where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history --- it would be quite appreciated!

I think it should be better to represent "very-very simplified at a level of profanation" the point of view that universe constitutes of rational and irrational parts (or there is this realm and there is the other realm).

Rene Descartes proposed philosophically based views on the duality of universe more than 400 year ago. He assumed that this realm is "extension in length,...

Dear Stephane and Pierre-Marc,

I really enjoyed your video on extra dimensions. I'm a fan of your cylinder analogy, and I appreciated the fact that you pointed out that the idea of extra dimensions, as promising as it is, unfortunately still remains untested. Let's hope for some exciting experimental results in the future!


PS: We would appreciate it if you could find the time to view and rate our own short video, Quantum Harmonies of Gravity .

Dear Stephane,

You managed to bring down to nonexperts some very difficult ideas of Kaluza-Klein and string theory, in an entertaining way. Good luck in the contest! And if you have time, I would appreciate if you will watch and rate my videos The puzzle of quantum reality and Can a black hole keep a secret?.

Best regards,

It seams like our votes are what matters in this contest.

So I'm asking for your vote. [I don't need to win, just a lot of votes rated 0.5, is enough]

My video says "Physics Needs a Paradigm Shift" but everybody knows that.

The purpose of the video is to recognize that NOW we know what has to be changed. That is what is new.

A paradigm shift means a scientific revolution.

I can't do it alone.

I need you !

(On friday I will vote for all your videos, with a 5. Thank you.)

The concepts presented in this video are really intriguing, and frankly, mind-blowing. Great work on the video. You made it really engaging. Rated you 4/5 stars. Would you mind also rating and reviewing my video? It's a short video that attempts to encourage the study of physics through fun visuals and animations.

Good luck on the competition!

Wonderful imagery! And the presentation here is captivating, even using translation. Voted it up.

Here's my Higgs Geometry video if you can have a look.

It's tricky to present the mathematics of symmetry breaking and particle physics to a popular audience, so I do appreciate feedback on it.

I am impressed!

As video, it is extremely well produced. It holds the viewer's attention from start to finish, and delivers the message well. Personally; I think it is better to have it be open ended, rather than tied in to string theory, because a general exposition of the rationale for higher dimensions makes the case more powerful.

I kept wondering if the flowers would be used as an example of dimensional ambiguity, as I often use them as an example when talking about non-commutative geometry. The distance across the flower varies, you see, depending on the size of the insect moving on it. But the video was full of suggestive images, hinting that the creators know more than they let on.

Well done!

I do think that the universe might have ten dimensions... Afterall we know a minute decimal of our universe which is infinity and hence the possibilities are uncountable...

Please go through my video also and rate it and give me your valuable suggestions... The topic of my video is - PHYSICS THE ODYSSEY...
