Word: Blaise Pascal
Definition: Blaise Pascal was a French mathematician, philosopher, and Jansenist who lived from 1623 to 1662. He is known for inventing an early adding machine and making important contributions to the theory of probability, often in collaboration with another mathematician named Pierre de Fermat.
In more advanced discussions, you might refer to his philosophical works, particularly his thoughts on faith and reason, or his influence on modern probability theory.
Blaise Pascal is a significant figure in mathematics and philosophy. His work in the 17th century laid the groundwork for many concepts we still use today.
