These posters would certainly be at home on any wall, but I especially like the idea of decorating a child's room or even a nursery with them. "Minimal Posters: Six Women Who Changed Science. And the World." were designed by Hydrogene and aren't available for purchase just yet. [Update, Sept. 28, 2012: I've edited out a reference to Hydrogene's previous, and funny, online handle, since Hydrogene has removed that information from Tumblr's "about" page.]
[Second update, also Sept. 28: Well, color me embarrassed. As two commenters point out below -- including possibly the anonymous Hydrogene, and if so hi! and sorry!! -- my (now-deleted) reference to the binary translation called it a derriere, and it wasn't; it was a kind of smiley. Shame on me for assuming I knew what the emoticon meant without the help of Urban Dictionary! Well, now I REALLY know what they say about people who assume.]
The posters celebrate Marie Curie, the first woman to win a Nobel Prize, with an image of the shell structure of radium, one of the two elements she discovered; Sally Ride, a physicist and the first American woman in space; Navy Rear Adm. Grace Hopper, one of the first computer programmers, who reputedly found a moth in a machine that became the original computer bug; ecologist Rachel Carson, author of "Silent Spring" and crusader against the pesticide DDT; Rosalind Franklin, whose painstaking research helped her capture the first images revealing the double helix structure of DNA; and renowned primatologist and anthropologist Jane Goodall.
