Finally, got to see
@drjohnodonoghue.bsky.social's talk in person @rsc.org His book Onscreen Chemistry: The Portrayal of Chemical Science in Film and TV is superb! Filled with so many nuggets of information I did not know. Bravissimo! Book signed 👍

One more day for #TECHOGNITION Hooray👏 Just a small sample of what will be on display. Of course, Michael Faraday used similar toys to explain centre of gravity in some of his lectures ⚖️🥚@techognition.bsky.social

A late one for #FluorescenceFriday! I found this flower (do not know the name) & when I peeled back the stem I saw bright yellow fluorescence under UV light.
