Hartry Field
Hartry Field is a person who likes to think about numbers and logic. He tries to understand how we can be sure about things that we say are true.
Think about the number 2. We know that 2+2=4 because we have learned it in school. But how can we be sure that it is really true? What if someone else thinks 2+2=5? Hartry Field tries to find ways to prove that certain things are true, and that everyone can agree on them.
He uses something called "mathematical logic" to do this. It's like a big puzzle that he tries to solve by putting all the little pieces in the right place. It's not always easy, but Hartry Field enjoys figuring out the puzzle and making sense of the world.
