English physicist Robert Hooke is known for his discovery of the law of elasticity (Hooke's law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory of ...

What was Robert Hooke's contribution to science?
Robert Hooke (1635-1703) is an English physicist. He contributed to the discovery of cells while looking at a thin slice of cork. He then thought that cells only exist in plants and fungi. In 1665, he published Micrographia.
Who was Robert Hooke and what was his biggest discovery?
Robert Hooke was a famous scientist, born in 1635. He most famously discovered the Law of Elasticity (or Hooke's Law) and did a huge amount of work on microbiology (he published a famous book called Micrographia, which included sketches of various natural things under a microscope).
What did Robert Hooke experiment with?
Hooke's most important publication was Micrographia, a 1665 volume documenting experiments he had made with a microscope. In this groundbreaking study, he coined the term "cell" while discussing the structure of cork.
How did Robert Hooke's microscope work?
To combat dark specimen images, Hooke designed an ingenious method of concentrating light on his specimens, as shown in the illustration. He passed light generated from an oil lamp through a water-filled glass flask to diffuse the light and provide a more even and intense illumination for the samples.
What was Robert Hooke's microscope?
Hooke was one of a small handful of scientists to embrace the first microscopes, improve them, and use them to discover nature's hidden details. He designed his own light microscope, which used multiple glass lenses to light and magnify specimens. Under his microscope, Hooke examined a diverse collection of organisms.
What contribution to science did Leeuwenhoek make?
Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
What did Robert Koch discover by using a compound microscope?
In the medical world, Louis Pasteur of France used a compound microscope to discover yeast fungus, while Karl J. Ebert, a German bacteriologist, employed a compound microscope in his discovery of Eberthella Thyphosa. It was also a compound microscope that Robert Koch discover tubercle and cholera bacilli.
What is Hooke's full name?
Robert Hooke FRS (/hʊk/; 18 July 1635 [N.S. 28 July] – 3 March 1703 [N.S. 14 March]) was an English polymath active as a scientist and architect, who, using a microscope, was the first to visualize a micro-organism.
Who discovered the microscope?
Every major field of science has benefited from the use of some form of microscope, an invention that dates back to the late 16th century and a modest Dutch eyeglass maker named Zacharias Janssen.
Did Robert Hooke make his own microscope?
Although Hooke did not make his own microscopes, he was heavily involved with the overall design and optical characteristics. The microscopes were actually made by London instrument maker Christopher Cock, who enjoyed a great deal of success due to the popularity of this microscope design and Hooke's book.
What was the magnification of Robert Hooke's microscope?
Micrographia, 1665. Robert Hooke (1635-1703) was an English chemist, physicist, architect, and surveyor. He designed microscopes, he didn't build them. His designs improved upon microscope mechanics and illumination, which improved resolution and increased the magnification to approximately 50X.
What did Louis Pasteur discover by using a compound microscope?
Louis Pateur and the Compound Microscope
Pasteur discovered another compound in wine called paratartaric acid that had the same chemical composition as tartaric acid. Most scientists assumed the two substances were the same.
