What is the difference between Medieval Europe and Renaissance Europe science?

Medieval Europe was really dark and dangerous. There was little to no traveling, no trading, and people were living and dying within a ten mile radius of where they were born as well. There were many poor people and little education as well. It was a time of isolation. However, the Renaissance changed all this. People got enlightened and started seeing the greater things in the world, and big trading was set up, education became a huge deal, and traveling became much more common. The Renaissance really got Europe back on its feet and there's a whole world out there, go explore it and gain knowledge.
