How Perspective Shapes Reality
Thanks to http://www.audible.com/minutephysics for supporting this video, which is about how the way we describe the world can influence the way we perceive it. In particular, with regards...

When Galileo pointed his telescope at Jupiter in 1610, he was the first person to see thegiant orbs attached to it by springs.His actual drawings, compared night after night, show these bright spots moving backand forth past Jupiter, exactly the same as if they were balls hanging off of springs.I mean, yeah Galileo was looking at the moons of Jupiter, but if you plot their motion backand forth and back and forth over time, it forms a sine wave.And that motion is mathematically identical to the motion of something bouncing up anddown on a spring with a linear restoring force - also sine waves over time.From a side-on perspective that projects two dimensions down to one, things in circularorbits look exactly like they’re springing back and forth on giant coils of wire.No...
