Today’s Google Doodle

August 4th is the birthday of logician and philosopher John Venn, best known for introducing the Venn diagram. A Venn diagram is a graphical representation illustrating multiple groups and their relationships to one another. Many internet memes have been made using a Venn diagram to illustrate funny and sometimes serious topics in the world.

Today, Google created a Doodle to illustrate Venn diagrams with simple equations and cute drawings as a way to pay homage to the man who created them. It even gives a little shoutout to Chris Hadfield, a Canadian astronaut who used social media to educate the world about space through YouTube and Twitter, and best known for his international space station rendition of David Bowie’s “Space Oddity”.
