Math and Science by Mail Club

Do you enjoy Puzzles and Challenges in Math or Science and want to learn more? We focus on the most interesting, unusual and obscure subjects and turn them into a year-long course of online activities, so that anyone, anywhere and at any time will be able to join in and learn - ...and, you can even stay in your pyjamas!

What is a Vampire number? Can you find a connection between ants and Facebook? How do you create optical illusions? What is the connection between rabbits, rectangles and gold? No matter what the time is or even if you are vacationing on the moon - as long as you have a computer and an Internet connection you can connect to the ‘Math and Science by Mail Club' and find all the answers. We have prepared digital books with dozens of pages of puzzles, experiments and magic tricks, and also videos and weekly challenges you can solve at home. Join thousands of participants from all over the world! Choose your language - Hebrew, English or Arabic.

The program is in its 34th consecutive year. In the past the program was run through the post and email, but over the years we have incorporated online interactive tools. Our world-renowned Weizmann Institute scientists are involved in writing the content, as well as personally leading ‘special events’ and conferences held within our online framework. 'Math by Mail' delves into topics in recreational math and led by metagrobologists Yossi and Michal Elran together with Weizmann mathematicians. ‘Science by Mail’ is dedicated to research currently taking place at the Weizmann Institute, allowing students a real glimpse into the world of contemporary research.
