Study Notes
Scientists and their Discoveries
-
Annie Jump Cannon (1863-1941): Leading 20th-century astronomer specializing in stellar spectra. Classified over 350,000 stars using a 1901 system, crucial for Harvard Spectral Classification.
-
Henrietta Swan Leavitt (1868-1921): Studied stellar luminosities at Harvard. Discovered a pattern in Cepheid variable stars, enabling distance measurements to other galaxies. Identified more than 2,400 variable stars and four novae.
-
Harriet Brooks (1876-1933): First Canadian female nuclear physicist. Studied under J.J. Thomson and Ernest Rutherford. Made discoveries in nuclear decay, though some were later attributed to others.
-
Srinivasa Ramanujan (1887-1920): Indian mathematician making major contributions to mathematical analysis and number theory. Despite limited formal training, sent a letter to G.H. Hardy with 120 theorems. Awarded a Bachelor of Science degree in 1916.
-
Erwin Schrödinger (1887-1961): Austrian physicist, known for the Schrödinger equation, a fundamental equation of quantum mechanics. His work revolutionized understanding of atomic structure and quantum behaviour.Studied physics in Vienna.
-
Ronald Fisher (1890-1962): British statistician and geneticist. Reconciled Darwin's natural selection with Mendel's discoveries using statistical methods. His work using statistics in scientific experimentation was important. Knighted in 1952.
-
Harold Urey and Stanley Miller (1893-1981; 1930-2007): American chemists. Simulated early Earth conditions in the lab using electrical sparks. Demonstrated how simple compounds could form from inorganic matter. Discovered that with heat and energy simple compounds could be produced.
Other important topics
-
Annie Jump Cannon's classification system: A system for classifying stars based on their spectral type and temperature. Cannon's system was crucial for understanding the evolution and properties of different types of stars.
-
Cepheid variables: Pulsating stars with a predictable relationship between their period and luminosity, crucial for measuring cosmic distances.
-
Nuclear decay: The process where unstable atomic nuclei naturally transform into a more stable state. This process involves emission of different particles or energy.
