Study Notes
Scientists and Their Achievements
-
Fred Hoyle (1915-2001): British astrophysicist who studied the origin of elements in stars. He proposed that elements form gradually through nuclear reactions within stars. He also supported the steady-state theory of the universe. Later in his career, he focused on organic molecules in comets.
-
Katherine Johnson (1918-): Award-winning mathematician who played a crucial role in calculating trajectories for many space missions. This included the Apollo 11 mission. She worked at NACA (National Advisory Committee for Aeronautics) and NASA, performing complex calculations manually.
-
Yvonne Brill (1924-2013): Worked in aerospace engineering. She designed propulsion systems for unmanned spacecraft and contributed to rocket design and weather satellite technology—even US Moon missions.
-
Abdus Salam (1926-1996): Pakistani physicist. His work was centered around uniting the electromagnetic force with the weak nuclear force. He developed the electroweak theory. His theories were confirmed at CERN (European Organization for Nuclear Research) earning him a Nobel Prize in 1979.
-
Vera Rubin (1928-2016): Astronomer who discovered that stars in the outer parts of galaxies move as fast as stars closer to the center. This challenged Newtonian gravity and helped prove the existence of dark matter. She observed 60 spiral galaxies.
-
Peter Higgs (1929- ): British physicist who proposed the Higgs field and the Higgs boson to account for the masses of elementary particles. This theory was important in understanding how particles gain mass. His work led to the development of the Large Hadron Collider (LHC) and the eventual discovery of the Higgs boson. His prediction had significant implications for particle physics. His theory was confirmed at CERN leading to the Nobel Prize in 1979.
-
Irene Uchida (1917-2013): Canadian medical geneticist who researched the effects of genes and chromosomes on human health. She investigated genetic conditions and congenital abnormalities. Research focused on how chromosomes and genes relate to health. Research included Down syndrome.
Additional Details
- NASA: The US space agency, which the mentioned scientists supported, and made significant contributions to.
- CERN: The European Organization for Nuclear Research where significant discoveries were made.
- Nobel Prize: Several of the scientists were awarded this prestigious prize for their exceptional contributions to their respective fields.
