Answer:
Made advances in science and math
Explanation:
Both Copernicus and Galileo were scientists. These two made advancements in the field of mathematics and science.
As a scientist Copernicus supported the heliocentric theory. Nicolaus Copernicus in this theory had proposed that the earth and other planets go around the sun. That is they revolve around the sun.
Galileo built the telescope to study heavenly bodies, this led him to support Copernicus. Because viewing through the telescope confirmed to him that Copernicus was right about the sun being center of the universe and not the earth.
