1932 - Pierre-Gilles de Gennes was born.Gennes was a French physicist who was awarded the 1991 Nobel Prize in Physics for generalizing methods to study order phenomena of simple systems to apply to complex forms of matter such as liquid crystals and polymers.
1911 - Nathaniel Wyeth was born.Wyeth was an American mechanical engineer who is best known for the invention of the PET plastic bottle. He was looking for a plastic that could contain carbonated beverages and used polyethylene terephthalate (PET) to solve the problem. PET bottles are recyclable and widely used throughout the world for both carbonated and non-carbonated drinks.
1804 - Wilhelm Eduard Weber
Weber was a German physicist who developed the first electromagnetic telegraph system with Carl Gauss. He also developed a system to measure electric currents and studied the magnetic field of the Earth. The SI unit of magnetic flux is named in his honor.
1632 - Antonie van Leeuwenhoek was born.
Leeuwenhoek was a Dutch natural philosopher who is considered the "Father of Microbiology". He was the first to use the microscope to observe and describe single celled organisms, or as he called them, animalcules. He also recorded microscopic observations of bacteria, spermatozoa, the banded pattern of muscle fibers and capillary blood flow.
1601 - Tycho Brahe died.
Brahe was a Danish astronomer who developed instruments to measure the positions and motions of stars and planets before the invention of the telescope. He cataloged over 700 stars with a high degree of accuracy using a nine-foot armillary sphere and his fourteen-foot mural quadrant. He also measured the positions of the known planets which became the data his assistant Johannes Kepler used to determine his laws of planetary motion.
