In what area where there advancements in the Middle Ages?

There were advances in just about every area of human endeavor in the Middle Ages. Among the most impressive were advances in law in the Early Middle Ages, and politics, philosophy, science and mathematics in the High Middle Ages and Late Middle Ages.

We tend to forget about some of the advances made during this time because they seem so obvious. Someone in Northern Europe of the 11th or 12th century invented chimneys. We take them so much for granted that we act like they were always there.
