Ironic Sans posted this idea years ago.
Scientist valentines. Go look; I'll wait.
The idea is genius, and my mind spun with ideas for more. (The creativity is more of a curse than a blessing, I say with as much false modesty as I can muster. Still though, important errands and tasks languished while I set these ideas to electronic realities.)
I've posted a baker's dozen, and hope to add more. I don't have David Friedman's artistic skills, so mine simply exploit images found via Google Image Search. I did try to find portraits made when the scientist was in his prime, rather than the more more prevalent "venerable sage" renderings. After that, I fiddled and fussed over each valentine in my favorite obsolete graphics program,
Canvas. The heart surrounded by a planetary-model atom graphic seemed like a good idea. Then I exported them as JPEGs, imported them in
Aperture, added captions, and published the set as a
collection on Flickr.
Featured scientists (so far) are Bohr, Celsius, Curie, Darwin, Galileo, Heisenberg, Kelvin, Newton, Ohm, Pauli, Sagan, Tesla, and Volta. For the physics-ly uninitiated, I included a brief explanation of each valentine. There's nothing that helps a joke kill so much as taking the time to explain why it's funny.
As a mark of highest flattery, I used a few specific scientist/slogan combos from the original Ironic Sans post. But I added a bunch of my own. I still have a few in the hopper, and there are countless more to be had, conjured by minds cleverer than my own.
Feel free to print and distribute them to appropriately deserving geeks. And I encourage you to develop the similar ideas that spring to your mind. Or leave your ideas in the comments so others might develop them.
There's still plenty of low-lying fruit here. Aristotle: "My natural place is by your side." Copernicus: "My world revolves around you!" Heinrich Hertz: "You and I are on the same wavelength." Charles Coulomb: "I get a charge out of you." William Gilbert: "You've got a magnetic personality."
