Why Time Might Not Be an Illusion
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.

The Complexity Conundrum
Resolving the black hole firewall paradox—by calculating what a real astronaut would compute at the black hole's edge.

Quantum Dream Time
Defining a ‘quantum clock’ and a 'quantum ruler' could help those attempting to unify physics—and solve the mystery of vanishing time.

Our Place in the Multiverse
Calculating the odds that intelligent observers arise in parallel universes—and working out what they might see.

Video Description

From Aristotle's theory of the spherical Earth to the discovery of the Higgs boson, this is an illustrated journey through the highlights of the history of physics. Part 1 tells the tale of how we discovered that there is one universal physics that applies to the entire observable universe. Part 2 explains how the fundamental forces of physics and the rules of quantum mechanics allow objects to keep their shapes. Part 3 describes the major breakthroughs of the past century, and speculates about what remains to be discovered.

Very well made video! I enjoyed your brief history of physics - it was done in such a way that made it interesting without feeling like it was dragging on. One of my critiques would be that the animation seemed to get a little repetitive as the video progressed. I understand that it's difficult to mix things up considering the content that you were covering, but I think a little more variety would have made it that much better. I really appreciate your first musical selection, I thought it was very fitting and fun. Overall solid video!

Dear Mr. Marc Séguin,

This is an excellent video which will provide, for science minded parents and grandparents, a wonderful presentation very clearly illustrating the physics/astronomy basics our young people should be familiar with. The animations/graphics deserve special credits.

Unfortunately, science is not well handled in our schools and I hope that this video gets to be widely seen on YouTube.

Good luck for the competition.

Hi Marc,

Thanks so much for reviewing my video!

I liked your video a lot; the animation was very good as well as the story line. I look forward to watching your other videos to see how you will expand on the topic.

Good luck in the competition!

Hi Marc

You have a lot of good information in your video. It lays out a great framework in explaining some of the history behind physics. My only suggestion would be to try to find a more creative way to present the information, so that it stirs today's generation to see how physics applies to their world. In other words, so that they can see how these early findings in physics still have current applications in determining and explaining things beyond science.

Again, very solid coverage of the information and great graphics.

Dear Marc,

Thank you for watching my video and posting your kind comments on my page.

I had seen your really nice three part physics story in full soon after it was posted. And I do intend to rate it, soon as I finish seeing all videos - I have a few left still :-)

My best wishes,

Hi Marc,

Thank you for your kind comments on the animation we did with PhD Comics on quantum computers. I watched your videos and you have done an excellent job explaining the journey of physics to its modern form.

Good luck!

I did watch this video quite a while ago and was very much impressed. I had forgotten to come back and rate it. It displays the highest technical prowess, and the explanations are perfectly clear. I particularly enjoyed the fact that the video is self-contained, requiring no prior knowledge and being accessible to young people, something we tried for in our video. The discussion of the word "force" was very nice. The only thing I would have liked to see that was not present was an explicit motivation for learning more about physics, but maybe that's in the subsequent videos.

Hi Marc,

We very much liked the 1st one on the series (still need to watch the other two but we thought we might as well make comments of each as we view them). The first in the series tells the important story (in a very good and well produced video) of how humans began to understand how the Universe works and how through the "reading what was written in the sky" people came across the beginnings of science. The story about how people figured out the Earth was a sphere (from the shadow it cast on the moon during a lunar eclipse) is great. There is also a related story that a Greek Eratosthenes of Cyrene (chief librarian of the Library at Alexandria) was able to figure out the radius of this sphere by measuring shadows in different parts of Egypt at a specific time of year. It is amazing how much people learned (and then forgot).

Anyway a very strong submission. We'll also take a look at your other videos.

Best of luck with the contest.

On added note -- we just noticed that you used Kevin MacLeod for some of the music to you video. we did as well. Good stuff.

Dear Marc,

Very beautiful videos with excellent explanations. Thanks for commenting on the first of my videos, and for suggesting to add subtitles. Actually, both the first and the second have subtitles, but you have to activate them on youtube. Good luck with the contest!

Great animations! I shall use them in my physics lessons! Great to see animations of the geocentric models, it makes retrograde motion much easier to fathom for high school students. Well done.

Very well done animations. Voted this video up.

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

There is a book called "Farewell to Reality" by Jim Baggott. It is about all of the nonsense and the fantastically ridiculous claims that the modern physicists are currently making a fortune off of. Mr. Baggott states, among other things, that the physics' community is playing games, not making sense in their advocacy of new ideas in physics, and that they are increasingly out of touch with...
