Femtochemistry is the study of chemical bond formation and breaking in real time, using ultrashort laser pulses on the femtosecond scale, roughly 10^-15 seconds, to capture molecular transition states as they happen. A researcher at Caltech pioneered this technique, allowing scientists to watch atoms bond during a chemical reaction rather than infer it after the fact. The work earned the Nobel Prize in Chemistry in 1999.

1:23:12at Caltech. He pioneered the field of phentochemistry and utilized this ultrashort laser pulses at the phentoc. So this is 10 -15 seconds to observe chemical bond dynamics as in >> chemical bonds are forming at that time scale right and he captured molecular transition states in real time which is it's just crazy that we can watch chemicals being formed >> right the atoms like hey and then and then it like becomes friends with the other atoms it's insane it earned him the Nobel Prize in chemistry in 1999 >> rightly so We are going to make a big jump to 1990 to 1992 Kobe mapping of the
1:23:57cosmic microwave background. >> Yes, this was astrophysicist John Mathther at NASA Gddard and George Smoot at UC Berkeley. They utilized NASA's Kobe satellite and the data from that to provide definitive confirmation of the big bang. So before we had Pensas and Wilson and Dicki, they had figured out that um you know the cosmo microwave background is a thing. Um but they had
