Another week of Twitter #weirdscifacts! It’s kind of hard to believe that I’ve been doing this for over 600 days straight.
620. Nov 23: Can’t beat this today: ‘Brinicle‘ ice finger of death filmed in Antarctic! Supercold brine descends, ever so slowly, to the sea bed, where it spreads rapidly and freezes everything in its path…
621. Nov 24: Dolbear’s Law (1897): the possibility to crudely estimate temperature via cricket chirp rates.
622. Nov 25: Wood frogs with natural antifreeze can survive up to 65% of body water freezing. I saw “The Muppets” on this particular day, so it seemed appropriate to use a frog-themed tweet!
623. Nov 26: In 1874, physicist William Thomson proposed to his future wife by signaling from ship to shore.
624. Nov 27: Because he couldn’t find a decent chemistry textbook, Mendeleev wrote his own & constructed the periodic table in process. It’s quite fascinating to think that the entire history of chemistry might have been different if the existing textbooks hadn’t sucked!
625. Nov 28: Flying frogs? Well, gliding frogs, but still weird! These are not as odd as the “flying snakes” that we’ve discussed previously, but I had a bunch of frog facts on hand…
626. Nov 29: Every calcium ion in your skeleton gets replaced about every 20 yrs! (h/t @krystaldcosta @bonegirlphd)
