Currently on display at the National Academy of Sciences is Fundamental Forces by Rebecca Kamen. Fundamental Forces is an exhibition of paintings and sculptures inspired the process of scientific discovery. The title Fundamental Forces refers to fundamental forces in physics: gravity, electromagnetism, and strong and weak nuclear interactions, and in my opinion, the exhibit really does provide a lovely representation of those fundamental forces. I loved the wire sculptures in particular as they were visually interesting and also looked like things I had studied in chemistry and physics class. Matter Informing Space reminds me of the Bohr model of the atom. The Doppler Effect is an interesting visualization of the Doppler effect, but it also reminds me of a vortex and the Coriolis effect. The sculptures also play with the light in wonderful ways. The shadows created by the wire sculptures and also Portal are incredibly interesting. If you are in the DC area, the exhibit is open until July 6, and it is free to see, so go.
