That is not only an awesome demonstration of physical principles, but also a superb demonstration of engineering skill. That must have taken forever to adjust properly.

This is the problem with the education system today. They don't teach you the concepts, they teach you how to pass the test.

I've always wondered why there seems to be a disconnect in many people between what one sees and what one draws. It seems like it should be so simple, but it's definitely not.

I'm looking at this more from a mathematics point of view. As in, you can make a multidimensional plot with axes defining different values and find ways of representing each value for each "point" on the plot. For example, if you wanted to plot a 5 dimensional function (one with 5 variables) you could use the 3 geometric dimensions, and for each point you could assign a hue to represent a 4th dimension, and a shade to represent the 5th.
You can only have 3 geometric axes, any geometric representation of higher dimensions is merely a projection of the actual object into 3-space.

Exactly, it's a hypothesis. Hypotheses are not fact. They are meant to be tested. Good luck testing that one though.

You can have only 3 mutually orthogonal geometric dimensions. But a dimension is just something that you can measure. Other dimensions could include, of course, time, but also: color, rotation, electrical charge, momentum, etc...

The A-10 Warthog is basically a giant gun with a plane built around it. There's actually more gun there than plane.

As cool as this is, I can't help feeling like it encourages bad lab practices.
