This one never gets old.
Carl Sagan Day.
As ever, my Cosmos in the Classroom curriculum materials are available to all. I'm using them this year in Physics as I have in the past for AP Physics: one episode per unit, sometimes shown in class the day after a unit test, and sometimes assigned as homework.
Last year, Netflix streamed episodes of Cosmos. They don't anymore. Hulu's Cosmos page anticipates the Neil deGrasse Tyson "reboot". (They did, anyway; the title graphic had been Cosmos: A Space-Time Odyssey, Tyson's title. Looks like they've now gone back to a "Cosmos: Carl Sagan" motif. The full title of Sagan's series was Cosmos: A Personal Journey.)
