Kary Mullis, developed a technique called Polymerase Chain Reaction or PCR. Nobel prize winner 1993. Basically it copies DNA. Really revolutionized the field of molecular biology... blew open forensics as it allowed very tiny evidence samples, that were previously too small for analysis, to now be copied so there is enough for plenty o' testing.
I just find it sad that more people (myself included) know about the day to day antics of people like the Kardashians, rather than the lives and contributions of people like Katherine Johnson, Kary Mullis, or one of my local Umass notables... the recently departed Lynn Margulis. We celebrate and elevate some really odd folks in our society.
Really hope to go see the movie, but it is more likely I will read the book and wait for it to hit the small screen, I just don't get to many movies.
