The attached video by Neil deGrasse Tyson, one of our contemporary geniuses and a true polymath, should be seen by everyone. It is especially appropriate since the March for Science is happening this Saturday. In addition to the main march in Washington DC, there are now 517 “satellite marches” around the world. See https://www.marchforscience.com/ People who believe in science are about to make a powerful statement.
There is nothing meaningful I can add to the video, so, uncharacteristically, I’m going to just put the Facebook link in here and urge everyone to view it. It’s only four minutes long.
