Every so often, YouTube throws videos into our feed that truly leave us speechless. Small gems shining among so much algorithmic mud, and worthy of being highlighted. The latest video Animation vs. Physics by Alan Becker fits perfectly into that category. They are 16 minutes that take us through physics concepts at multiple levels, from the basics like distance and speed, to darker elements for the public like anti-de Sitter space-time, and the Calabi-Yau manifold.
Many people believe or feel that physics is not an accessible science. Personally, I admit that it is very broad and deep, but I must also mention that I have had terrible physics teachers in the past, and I was not the only one. Something similar happens with history: the "experts" repeat it as if it were a recording, to such an extent that they eliminate the desire to learn…
… but fortunately there are things like "History of the entire world, I guess" by Bill Wurtz, a video that I have not tired of recommending, despite the initial language barrier of English (there are already several copies subtitled in Spanish). Now, how hard would it be to make an equivalent to that video, but focused on physics? I mean something accessible, pleasant, dynamic. Today, I think the answer is in "Animation vs. Physics" by Alan Becker, whom we know well from his "Animation vs." series.
"Animation vs. Physics": From Speed to Black Holes in 16 Minutes
The adventure of the orange character begins with basic concepts: Distance, speed, displacement, acceleration, friction. The first objects give rise to force, work, angular momentum, torque, kinetic and potential energy. At the end, a combination of these concepts helps him reach space, escaping local gravity with a rocket.
But space is enormous, and his maximum speed is far from ideal. Several gravitational assists and the use of magnetic fields to accelerate (basically turning into a railgun projectile) allow him to reach 80 percent of the speed of light. However, that is still the "simple" part. His destination is nothing less than a black hole, and when he throws himself into its interior in the best Dr. Strangelove style, physics changes to a completely different level.
Universe sheets, conformal field theory, anti-de Sitter space-time, probability waves, Calabi-Yau manifold, Tipler cylinder, Einstein-Rosen bridge (yes, the famous wormhole)… all these very low-level ideas have been represented (however brief their mention) in a formidable way. A simple search of those terms inevitably throws us into a mathematical labyrinth that few can navigate successfully… but if the plan was to plant a seed of curiosity, the video fulfilled its objective.
