Study Notes
Annie Jump Cannon
- American astronomer who specialized in stellar spectra.
- Worked at the Harvard College Observatory for over 44 years.
- Classified over 350,000 stars using her 1901 system.
- This system laid the groundwork for the Harvard Spectral Classification system.
Henrietta Swan Leavitt
- Astronomer who studied at Radcliffe College and the Harvard College Observatory.
- Observed Cepheid variable stars and discovered a regular pattern in their brightness.
- This discovery was crucial for measuring distances to other galaxies.
- Discovered more than 2,400 variable stars and four novae.
Harriet Brooks
- First female nuclear physicist in Canada.
- Graduated from McGill University and studied under J.J. Thomson and Ernest Rutherford.
- Worked in Marie Curie's laboratory and made a significant discovery.
- Her research showed that one element can transform into another through nuclear decay.
Srinivasa Ramanujan
- Indian mathematician who made significant contributions to mathematical analysis and number theory.
- Had minimal formal training but excelled in mathematics.
- Sent theorems and ideas directly to G.H. Hardy in Cambridge.
- Awarded a Bachelor of Science degree in 1916 and elected a Fellow of the Royal Society.
- Died in 1920 from tuberculosis.
Erwin Schrödinger
- Austrian physicist who studied physics at the University of Vienna and the University of Zurich.
- Developed a wave equation that revolutionized the understanding of quantum physics.
- His work provided a new interpretation of atomic electrons as "clouds" of probability rather than fixed orbits.
- His contributions significantly changed the way we view atomic structure.
Ronald Fisher
- British statistician and geneticist who pioneered the application of statistics to scientific experimentation.
- Reconciled apparent inconsistencies between Charles Darwin's ideas on natural selection and Gregor Mendel's experiments on inheritance using statistical methods.
- Published a detailed paper in 1918 explaining the use of statistical tools.
Harold Urey and Stanley Miller
- American chemists who simulated early Earth conditions in the laboratory to study the origin of life.
- Their experiment used electrical sparks to simulate lightning, producing organic molecules from simple inorganic precursors.
- This experiment showed that organic molecules could be generated from inorganic materials under early Earth conditions.
