Acapella Science has put together a great little song giving you the history of Exoplanets, from its beginnings back in 1990 to the present, culminating with the TRAPPIST-1 discovery. You have to appreciate him when he says I’m a harmony addict working on a master’s in theoretical physics; what ELSE was I going to make a YouTube channel about? This is his latest, but far from his only such production; he tries to crank one of these out each week. So I thought I would include a few more, with Entropic Time for the second tune, and the final one is CRISPR-Cas9 (Bring Me A Gene). I don’t usually include videos with a stinger at the end hyping the person’s channel, but this isn’t just music, it is science at the same time, and that is a combination worth supporting. The man creating these is Tim Blais, and I hope he keeps making these for a long time to come.
