Stars died so that you could live

“The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics:

“You are all stardust.

“You couldn’t be here if stars hadn’t exploded, because the elements — the carbon, nitrogen, oxygen, iron, all the things that matter for evolution — weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.


Swiss Dufour Map First Edition

It’s amazing that Swiss people created the maps of their country at this accuracy 150 years ago, and made the digital version of them publicly available so that you can still look them up and compare with modern maps.
