56:54This was physicist Edwin McMillan and Glenn Seabborg. They were working out of Berkeley and they expanded the periodic table with human effort. This is huge, right? Because now we are making things that the universe doesn't create. >> We're literally making it, right? >> Yes. >> This is crazy. um they created neptunium and plutonium that are the first trans uranium elements. So like the periodic table usually ends at uranium and if humans had nothing to do with it, it would end at uranium. But on earth we have other elements. These are the first guys to do it. 1951 Nobel Prize in chemistry >> and maybe the aliens have expanded even
57:34on our periodic table. This is where we start getting packed everybody because this is backto backto back. Here we go. 1940 development of blood plasma banking. Yes, this is physician Charles L. R. Drew. Um he was a black physician and doctor and he developed the protocols for mass blood plasma separation and long-term preservation at Columbia University and the Presbyterian Hospital in New York City. His work enabled the creation of the first mass blood bank. um he had to go through a
