Transcript of John Venn

How Venn Impacted Other Fields
Venn impacted many other fields, but the three main ones were mathematical logic, probability theory, and the philosophy of science. The Venn diagram and sets helped these three fields greatly. It helped extend them to newer and higher boundaries, plus do the math easier and in a more organized way.

More About John Venn
Impact Because of Contributions
Because of John Venn's spectacular invention and contribution to mathematics, many new forms o technology were invented. We also have a way of knowing the differences and similarities of many different objects, places, and people.
About John Venn
John Venn, well known today for inventing the Venn diagram, was a British philosopher and a logician . He was born in Hull, England, on August 4, 1834, to a prominent Anglican family. His father was the Reverend at the neighboring church. Venn's family was very religious. His mom died when he was young, leaving him with his father for the rest of his childhood. He hated books, and someone quoted, "
... so slight an acquaintance with books of any kind that he may be said to have begun there his knowledge of literature."
After graduating from Cambridge College, he was a priest for a short time but then returned to Cambridge as a lecturer in Moral Science, teaching and studying probability and logistical theories. Venn had other interests, too. He loved to buid machines and had a rare knack for it. He used his skill to build a machine for bowling cricket balls which was so good that when the Australian Cricket team visited Cambridge in 1909, Venn's machine beat their top cricket player four times in a row! Venn was also a keen botanist and a superior mountain climber.

Contributions to Mathematics
Example of A Real Set
A set looks like many circles overlapping one another. Each circle is labeled with a variable, such as
x
or
y
. Normally numbers are in every space inside the overlapping circles, representing what number the variables have in common.

Before Cambridge in 1867, Venn married Susanna Carnegie Edmonstone. They had one child, a son John Archibald Venn. While back at Cambridge, Venn spent his time both teaching and studying probability theory and logic. At the college, he developed a method of using diagrams to illustrate set theory, called Venn Diagrams. It was made up of two overlapping circles, which made it easier to represent sets. Everyday Venn diagrams show the similarities and differences between two properties. Venn diagrams also help a type of logic called Boole logic, after the famous 19th century George Boole. Venn published Symbolic Logic in 1881 and The Principles of Empirical Logic in 1889. He then devoted himself to studying the history of the college and the history of his family until his much later years after retiring. In 1883, John became a Fellow of the Red Society. In the same year, he became a Doctor of Science at Cambridge. Sadly, he died in Cambridge, England, twenty years after he became the President of Gonville and Caius College in 1903, at the age of 88.

John Venn had many contributions to mathematics. He invented the Venn diagram, which shows differences and similarities between two objects, places, people, etc. The Venn diagram can also show set theories, which plays a huge part in advanced mathematics. Venn made the most important contributions to mathematical logic, probability theory, and the philosophy of science. He also developed Boole's symbolic logic and worked on the frequency theory of probability.
Even though John Venn had a strict and sorrowful childhood, he grew up to be a famous mathematician and had many contributions to the world of mathematics. He impacted other fields and inspired many math lovers to contribute to mathematics and find a new way of doing things. Years of education took him far.
