Task 8 geography Antoie Van Leeuwenhoek & Robert Hooke
Antoie Van Leeuwenhoek was a Dutch tradesman and scientist. He is commonly known as "the Father of Microbiology". Using his handcrafted microscopes, he was the first to observe and describe single-celled organisms, which he originally referred to as animalcules, and which are now called microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa, and blood flow in small blood vessels. Leeuwenhoek did not author any books; his discoveries came tolight through correspondence with the Royal Society, which published his letters. By the end of his life, Leeuwenhoek had written approximately 560 letters to the Society and other scientific institutions concerning his observations and discoveries. Even when dying, Leeuwenhoek kept sending letters full of observations to London. The last few also contained a precise description of his own illness. He suffered from a rare disease, an uncontrolled movement of the midriff, which is now named Van Leeuwenhoek's disease. He died at the age of 90, on August 26, 1723 and was buried four days later in the Oude Kerk he is noted for his role on the information that he provided for cells on cells.Antoie Van Leeuwenhoek played a big role in what we know today about cells.,and will always be remembered.
Robert Hooke
In 1665 Robert Hooke used a microscope to examine something that would change the world forever. Robert Hooke was perhaps one of the most important scientists from the 17th century.When Hooke viewed a thin cutting of cork he discovered empty spaces contained by walls, and termed them cells. The term cells stuck and Hooke gained credit for discovering the building blocks of all life. Hooke calculated the number of cells in a cubic inch to be 1,259,712,000, and while he couldn't grasp the full effect of his discovery, he did at least appreciate the sheer number of these cells.Robert Hooke wrote Micrographia, the first book describing observations made through a microscope.
