We use the fundamental group to prove the Brouwer Fixed Point Theorem which states that any continuous map from the disk to itself leaves at least one point fixed. We also prove Borsuk-Ulam which tells us that there are two points on the opposite sides of the earth with the exact same temperature and barometric pressure.
