Memrise’s Periodic Table
Memrise is best known for its foreign language resources. It is an app/site that associates each word, or in this case element, with an image. It was co-founded by world memory competitor Ed Cooke, who was featured in the New York Times bestseller Moonwalking With Einstein. With the method of loci “memory palace” system best known for its use in Sherlock, you can mentally file these images to help memorize the Periodic Table in order. Crazy, and it works. With Memrise, I was able to memorize the Periodic Table in a week.
