5. Famous words
"My work, which I've done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a craving after knowledge, which I notice resides in me more than in most other men. And therewithal, whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that all ingenious people might be informed thereof." - Anton Van Leeuwenhoek Letter of June 12, 1716
A world filled with creatures that all humans have never seen
