To remember information such as number sequences, your brain uses its short-term memory storage. Your short-term memory has a limited amount of space to store information.

Now, UNSW Honorary Professor Norman Wildberger has revealed a new approach using novel number sequences, outlined in The American Mathematical Monthly journal, with computer scientist Dr. Dean Rubine.

A relatively useless pseudo-random sequence with a period of seven bits is the result, but the point of this circuit is to educate rather than its utility.
