Harvard’s School of Engineering and Applied Sciences will again hold its Holiday Lecture virtually this year, on December 11 at 1PM. This year’s topic is Go With the Flow: A Festival About Fluids. Before the webinar, please register here and also visit this page to submit photos and words to be combined into a word cloud about fluids. That page will also soon have lists of household materials to gather for use in demonstrations during the webinar, as well as experiments you can do at home.
