Mathematics, geometry. Retweet if you can find a perfect Five-Pointed Star in this pattern. [From Sam Loyd (1841–1911)] Before you show the answer, why not first share this with friends who might want to see the puzzle, before seeing the answer?

The first time I heard the word "cis" was in high school chemistry.
Don’t tell them about the cis and trans molecules in organic chemistry they’re gonna lose their shit! And definitely don’t say anything about cis and trans regulatory elements in molecular biology!! 🥸

This cover of “The Icosahedron” by Felix Klein reminds me of Westerns or Science Fiction I used to read as a teenager. But 👋🏼 this was a great adventure that Klein was embarking on, wasn’t it?
