This is it — today marks the 2-year anniversary of Twitter #weirdscifacts, meaning I’ve been posting facts on Twitter every day for 2 years straight! Not sure what I’ll do with the facts next — trying to decide by next week how to proceed…
725. Mar 07: Electrician gets a Licthenberg tattoo from a lightning strike! (via @swansontea) Lichtenberg figures are branching, fractal-like figures that can be burnt into materials via electrical discharges. Apparently people struck by lightning get similar figures relatively often. (Image via Wikipedia):
727. Mar 09: Sperm discovered doing basic calculus! Well, perhaps that’s a bit of an exaggeration, but sperm have been discovered to direct themselves based on changes in concentration of calcium, which is essentially the calculus action of taking a derivative! (h/t @sciencegoddess)
729. Mar 11: Einstein, 1934: “There is not the slightest indication that [nuclear energy] will ever be obtainable.” Many prominent scientists, engineers and visionaries have made strong predictions that turn out to be rather absurdly wrong.
730. Mar 12: The 1967 earthquake in Konya, India: likely caused by the filling of a new dam reservoir. With all the discussion of the likely connection between “fracking” and earthquakes, more attention has been focused on earlier quakes induced by human action.
