Every Force in Nature (Theory of Everything, Part III)
In which we explain economic equilibrium, how to make money from nothing, and every fundamental force in physics.
If you'd like to read a (very) rigorous description of gauge theory in economics, check out this paper by Lee Smolin: http://arxiv.org/pdf/0902.4274v1.pdf
And if you're an economist rather than a physicist, check out "The Index Number Problem: A Differential Geometric Approach" by Pia Malaney: http://bit.ly/JKS5lh
What if you thought the earth was flat? And then you found out it isn't?

How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

This video is chapter 6 in my series on special relativity, and it covers the topic of relativistic addition of velocity: aka, how things that are moving relative to one inertial reference frame, which is moving relative to another reference frame, what speed or velocity are those things moving relative to the second frame. We'll show this using the Lorentz transformation of moving worldlines, enacted with a mechanical minkowski diagram, aka mechanical Lorentz transformation, aka spacetime globe.

The moon may be 1.3 light-seconds away, but why on earth do we measure distances using time?

This video is about Simpson's paradox, a statistical paradox and ecological fallacy where seemingly contradictory results are implied by a single set of data depending on how it's grouped. The paradox can arise in medical studies, student test scores, and so on.

This video is about the definition of a day, and how it applies (or not) on the sun. Solar day, sidereal day, universal coordinated time (UTC) day, etc. Length of a day.
