Who was John Venn? Who was responsible for the Venn Diagram? Is there a place in education for "random episodes of learning?\"?

Random episodes of learning take place when Google changes its logo to celebrate the lives of "obscure" people.

John Venn, FRS^[2][3] (4 August 1834 – 4 April 1923) was an English logician and philosopher. He is famous for introducing the Venn diagram, which is used in many fields, including set theory, probability, logic, statistics, and computer science.

This demonstrates the need for "short learning moents" as long as we have time to integrate the bits into our current database.
