Here are some other candidates to be on the $20 bill, or other units of currency (almost all are Americans)
Edith Clarke, mathematician, electric power pioneer
Cecillia Payne, discovered how stars work
Annie Bell, compiled data for Cecillia Payne
Marie Tharp, discovered continental drift
Rosalind Franklin, x-ray crystalography critical to discovery of DNA
Grace Hopper, inventor of COBOL, computer science pioneer
Radia Perlman, RSTP, etc., "The mother of the Internet"
Bella Abzug, Mayor of New York
Golda Meir, 4th prime minister of Israel
Catherine the Great, architect of Modern Russia
Marie Curie, discoverer of radioactivity
Lise Meitner, first to explain nuclear fission, 109th element "Meitnerium", director at Kaiser Wilhelm Institute
Murasaki Shikibu, authoress of the world's oldest novel, The Tale of Genji
So, for starters, the Internet, the world's most popular computing language (through the 90s anyway), some of the most important phenomena that make our world work which we didn't understand AT ALL before: continental drift, that stars are made of mostly hydrogen, how they work, etc., what radioactivity is, how nuclear fission works, what's weird about the weak nuclear force, the idea that fields and particles can produce our reality, that we don't know what 95% of The Universe is made of, and what DNA is and how it's structured, and don't let's forget transmitting power over long distances with electricity, among many other things, were ALL the accomplishments of WOMEN.
So how atoms and quantum physics work, how stars work, how our planet works, how the code that makes up all living things works, how computers and computer networks can be harnessed and used, how electricity can be harnessed and used. Major participation in politics, literature, and culture.
I wrote another little piece on great women of our time.
Things were looking really bad mid-November, but there's been a downtrend in doubling times and projected deaths. Mid-November we were looking at 600,000 America deaths by Inauguration Day, which dropped down to half a million, and now we're looking at maybe 450,000 US deaths by January 20.
The doubling times have gone from about two months towards three months, so that's good. Instead of twice as many sick and dead Americans, Texans, and Idahoans, it's only every three months that we have twice as many. This is still not great, obviously.
