I know that, if you release a bowling ball and a feather from the same height in a vacuum, they will hit the ground simultaneously. That their difference under normal conditions comes entirely from the air resistance which a feather experiences. And that people have understood this for centuries.

I know that everything about spacecraft propulsion and routing depends on this fact, and that this has been verified over and over again by the fact that we can, for example, land on the Moon or Mars.

But still, watching it be done from a height of several stories in the world's biggest vacuum chamber, it's still kind of amazing that it works. And apparently the people doing the test, experienced scientists and engineers all, find it kind of amazing too.

TL;DR Non-celiac Gluten sensitivity doesn't exist.

Says the scientist who once thought it did. He checked again and found out he was wrong. That's science!

If it actually gets built (questionable) it would be right across the street from my office.

“Oh, come on, Jesus,” Pious Paul protested. “Don’t go socialist on me again. Please don’t encourage class warfare. The best way to help the needy is to give public money to the rich. [...]"
