A Universe Springs From Nothing
Are we just a statistical fluctuation?
Only the fourth basic electrical element, joining resistors, capacitors and inductors.
This seems like a typical bike trick video, until you realize that most of the "footage" was taken using a remote control helicopter, and a standard HD camera. Real budget effort. The quality, for a backyard project at the time, is striking. Gyro stabilization, camera control, video link, lotta things going on here. And the bike tricks aren't bad either. If no one is playing what you want to hear, buy an instrument, learn to play it, and play what you want to hear.
Video Projection - on steroids
This is use of light projection on a grand scale. A new form of camouflage?
3D Animated Characters on Stage with real people?
Here is how Madonna shared the stage with animated characters (Gorillaz) during the Grammys one year. An interesting projection system, combined with a lot of artistic ingenuity. 3D projection, and not that complex to execute.
The best video I have seen on the experiments to determine whether light is a particle, or a wave.
This guy demonstrates how a single person can use wood, sand and stones to juggle huge stones, and make monuments all by himself.
Deriving Einstein's most famous equation: Why does energy = mass x speed of light squared?
You can follow this with only second year college calculus. May twist up your brain a bit.
How Did They Build the Pyramids?
How did ancient people juggle big stones over large distances and heights? This would work.
How Did They Build the Pyramids II?
Geopolymers is one way. Long video, but has some important conclusions in it. Doesn't answer everything, but better than anything else I have seen.
Parallel Execution - On a grand scale.
Changing the distance between the rails (gauge) of over 11k miles of railroad track to ALL be the same, and ALL the rolling stock that used it. In 36 hours. In 1886. Those telegraphs must have really been humming.
