== Gunpowder was brought to England during the 16th century. Gunpowder was a huge advancement in warfare. It started with cannons shooting huge led balls then to muskets and so on. (Schlager)

Another major development in the science world was the microscope invented in 1590 by Zacharias Janssen and his father in Holland. It was a compound microscope with two lenses. The microscope was used for viewing things too tiny to be seen by the naked eye. It used concave and convex lenses to bend light and greatly enlarge images. (Schlager)

Using the idea of the microscope to guide him, Hans Lippershy of Middleberg decided to invent the telescope in 1608. Lippershy thought that if a microscope could enlarge images too small for the naked eye to see, there must be a way to enlarge objects too distant for which to get a good view. (Schlager) The submarine was invented in 1624 by a man named Cornelius van Drebbel. However, Leonardo da Vinci drew out the basic concept of a submarine over one hundred years before. Drebbel, a Dutch inventor and engineer employed by the British navy constructed a leather- covered rowboat from which oars protruded through watertight seals. Drubbel's ship could stay underwater for a few hours, but it only went about fifteen feet under the surface. ( Schlager) Robert Boyle invented the match in 1680. Although fire could be made by rubbing sticks together or by striking flint to steel, this was a time consuming process. Boyle discovered that when phosphorus and sulfur were rubbed together, they would burst into flame. Boyle knew that this was not because of friction, but because of chemical nature of these two substances. Although convenient, Boyle's matches were not very safe, because sometimes they accidentally went up in flames while in a pocket. (Schlager)
