Steve Cohen @drstevecohen.bsky.social · 08/10/2026J.J. Thomson announced the discovery of the electron this month 129 years ago, in "Cathode Rays," Phil. Mag., 44, 293-316 (1897). (G.J. Stoney had already coined the word "electron" in 1891.) #ChemSky #ChemChat 🧪 Read his paper here: web.lemoyne.edu/giunta/thoms...web.lemoyne.eduJ. J. Thomson 1897 162
Steve Cohen @drstevecohen.bsky.social · 07/10/2026Le Bel simultaneously with Van ‘t Hoff had the idea that ”chimie dans l’espace” meant molecules had 3-D shapes. Here is his 1874 paper. #ChemSky #ChemChat 🧪 babel.hathitrust.org/cgi/pt?id=hv...babel.hathitrust.org 030
Steve Cohen @drstevecohen.bsky.social · 07/10/2026This year’s Chemis try Nobel Prize is about chirality, so here is the original paper by Van ‘t Hoff from 1874 showing chirality and 3-D atomic position in molecules are related.

Steve Cohen @drstevecohen.bsky.social · 01/09/2026I am going say something that may be controversial, as a co-author of “America’s Scientific Treasures“, 2nd ed. We did NOT include this museum in our book because it catered to kids, not adults. Yes, it’s historic, but other museums have figured out how to move on; whereas ANS hasn’t. 010
