Since I was so bad at drawing 3d structures for molecular geometries, I looked for something that would help students visualize them. I found the perfect free combination 😃 Tinkercad to create & Sketchfab to display. Since I'm retired, hope others can use them #ChemSky

Something's not the right size? We don't just make it bigger, we make it look good too.

Chemix isn't just for chemistry, try us for biology set ups too. Anything we're missing? Let us know.

Still trying to organize all these books since I picked up a few more when I visited @vortexbooksncomics.bsky.social 😊
Think most of @briankeene.bsky.social books are organized along with @marysangiovanni.bsky.social, @somercanon.bsky.social @mattwildasin.bsky.social, @kozeniewski.bsky.social,...

AI can do some impressive things, but drawing accurate lab diagrams isn't yet one of them... That's not a Liebig condenser. Equipment is mislabelled. And what's that contraption on the right?
Maybe best to stick with Chemix for now 😉. #MadeWithChemix #EduSky #ChemSky

That was a nice 2620 mile road trip.
Thanks again to @marysangiovanni.bsky.social and @briankeene.bsky.social for making my visit to @vortexbooksncomics.bsky.social Awesome! 😊 Can't believe I got to hang out with y'all. I might have been fanboying a little bit 😆

Thanks @marysangiovanni.bsky.social for signing my books! I'll try to see if I get you to sign Thrall in 7 years for the fourth autograph 😁
If I remember correctly the first one was from WHC 2011, the second one was @killerconaustin.bsky.social 2018 and today's was @vortexbooksncomics.bsky.social 😊

Bought this book @vortexbooksncomics.bsky.social so @ronaldmalfi.bsky.social could sign it. But after mentioning DC House of Horror to @briankeene.bsky.social, he said that Malfi was in that one...
Now I'm torn... Sign book or comic 🤔
