Did you know that the most perfectly smooth and accurate spherical object ever created by human kind was a 1.5" diamter piece of fused quartz (glass)?
I did, and so did Wikipedia (This round is a draw, Internet)!
It's true, this little marvel of modern material engineering was made by NASA for use in "Gravity Probe B". Gravity Probe B was one of the most remarkable, elaborate, and ultimately triumphant examples of experimental physics that confirmed Einstein's assertions about effects of gravity on space-time. It also has nothing to do with rest of the content of this blog post, except for the part about glass spheres.
This past Monday, just before becoming horribly ill (again), I spent the evening in the hot shop making a whole bunch of little glass spheres. At the end of the night, just before 1:00am, I thought that the process might make some good internet. So, I propped my camera on a brick and shot this video outlining the process of making a "perfect" glass sphere out of hot glass, by hand. In this case, "perfect" is being used quite subjectively, but you get the point (You win this round, NASA)!
