Things to do with dead physicists

Yes, yes, you can make a statue of them and then put their remains inside the statue. Alternatively, you can make a giant asymetrical space shuttle and let them drift around in space (Lebbeus woods' design for Einstein's tomb) - or you can make a gigantic cenotaph with holes in the domed roof in the pattern of the constellations (Etienne-Louis Boullée's Cenotaph for Newton). When Newton died, he was the first scientist in England ever to get a tomb as good as a poet. You wait a few years, and now no one's interested in dead poets drifting in space. (More here and here, and a beautiful collection of giant spheres at cabinet here).
