Blaise Pascal was a mathematician with a great impact. He began his mathematical journey from a young age, and, throughout his lifetime, made significant contributions in geometry, probability, philosophy and religion. Toward the end of his short life, Pascal became focused on his faith, which led to a change in his thoughts and has served as an example to Christian mathematicians ever since.
