Storyboard Text

  • If people make machines that make distant objects look nearer then why don't i make a machine that can view smaller things?
  • In the Early 1600's, Netherlands, Zacharias Jansen came up with the first compund microscope
  • Every scientist wanted to get a hand on the microscope Jansen has made and apparently Anton Van Leeuwenhoek, a fellow dutchmen, who heard about these microscopes did not want to buy one so he decided to make his own.
  • Let me just make my own microscope, I'll even make it better.
  • Let me tell my scientific colleage, Robert Hooke about my discovery!
  • What is this dirt? It looks like little animals, I'll call it "animacules"
  • Once Leeuwenhoek had created his own microscope he looked at everything and anything he could look at and saw bacteria.  He was also sending letters to Robert Hooke, a scientific colleague in England
  • I shall call the little chambers "cells"
  • Hooke was a guy that loved science. He is the man that we can thank for the term "cell" as he was looking at a piece of cork under his microscope and the little chambers that he saw reminded him of prison cells.
  • All living things are made up of cells!
  • Fastforward to the 1800's where two German scientists discovered the cell theory. The first scientist was Mat Thias Schleiden, a botanist who studied plants under the microscope. He later discovered that all plants were made out of cells.
  • Cells came from pre-existing cells.
  • At the same time at the other end of Germany was Theodore Schwann, a scientist that studied animal cells, reached out to Rudolf Virchow to prove that cells came form pre-existing cells. Which  sums up the cell theory.
  • Exactly
