In celebration of the life and legacy of the British logician and philosopher John Venn, Google doodle treats visitors to the search engine homepage with an interactive Venn diagram. The doodle can be seen in all parts of the world.

At the very first sight of the Google home page, visitors can immediately spot the interactive Venn diagram forming the two letters "o" of the word Google. When clicked, it will show two circles with five tiny circles each showing diagrams of the choices that one can pick to match.

On the left circle, the choices are major categories which include musical, mammals, transport, vegetation, and sea life. On the right circle, the choices are descriptions with include tiny, has wings, thrives in cold, has snail, and mythical.

For instance, when one clicks the image of "mammals" on the left circle and the image of "thrives in cold" in the right circle, it will show an image of the bear with falling snow in the overlapping center of the Venn diagram. In another case, when one clicks an image of musical on the left and the image of mythical on the right, it will show an image of an astronaut playing the Bowie song on the guitar at the overlapping middle part of the Venn diagram.

According to Teacher Vision, John Venn was a famous mathematician who was best remembered for his contribution on the study of probability and Mathematical logic. He developed the Venn diagram which uses circles to sort groups and illustrate the relationships of one group from the other in a logical and visual manner. The Venn diagram is an integral part of many fields of knowledge like logic, computer science, set theory, statistics, probability, and psychology.

John Venn lived from 1834 to 1923. He was an alumnus of Cambridge University in 1857. Two years after, Venn was ordained into priesthood. He was a curate for one year then he went back to Cambridge and taught Moral Science.

Venn wrote several books which were highly original and significant development in the field of statistics. In 1866, he wrote a book entitled Logic of Chance and another book entitled Symbolic Logic in 1881. In 1889, he also wrote another Principles of Empirical Logic. With his commendable and breakthrough development in the field of logic and math, John Venn was elected as a member of the Royal Society in 1883.

The Google doodle project lead and designer Mike Dutton explained the concept behind the interactive Venn diagram. He explained the tricky part in properly communicating how the Venn diagram actually works. While the interactive Venn diagram looks like a kid's game instead of a usual doodle, the style in presenting the Venn diagram shows the education and fun side of studying the concept.
