The USPS ceremony for the Forever stamp in honor of 吴健雄Prof. Chien-Shiung Wu.

The USPS ceremony for the Forever stamp in honor of 吴健雄Prof. Chien-Shiung Wu. It’s at 11am on Thursday, Feb. 11. https://about.usps.com/newsroom/events/chien-shiung-wu-commemorative-forever-stamp-ceremony.htm

She was a Chinese immigrant who became a nuclear physicist in an almost entirely male-dominated field in the 1950s. She worked with Oppenheimer and Fermi on the Manhattan Project, helping develop the method for separating nonfissionable uranium 238 from fissionable U-235—the bomb’s key fuel. Her experiment on the non-conservation of parity disproved a fundamental law of physics that had been considered incontrovertible for 30 years. The male theoretical physicists she worked with got the Nobel Prize, but she didn’t get it this time, or for earlier work on Beta decay that was also considered Nobel-worthy. She’s one of only two individuals being honored with stamps this year, and in a year that the USPS is honoring Asian-American achievement. The art for her stamp was done by Asian-American painter Kam Mak.

Please tell any Asian-American, immigrant, Chinese, or Women in Science groups who might be interested in promoting this event on 2/11. Buy the stamp! https://store.usps.com/store/product/buy-stamps/chien-shiung-wu-S_480204
