Scientists have also successfully built logic gates by using swarms of soldier crabs. It takes about 80 🦀 to operate a logic gate, and there are 8 logic gates in a byte, so 640,000 crabs can be used to store a single tweet. Which seems kind of horrifying. 🦀🦀🦀🦀🦀🦀🦀🦀

For the new followers today, here’s a, “I just discovered crows are awesome,” starter pack: 1) Crows can live a long time (14-17y), and are generally territorial. That means the crows you interact with outside your home/work may be the same individuals for over a decade.

[Thread] In 1482, Da Vinci wrote out a letter and a list of his capabilities and sent it off to the Duke of Milan, hoping to get employment. "... I have methods for destroying every fortress (...) Also I can execute sculpture in marble, bronze and clay." See the next tweets.
