Study Notes
Henry Stommel: A Pioneer in Oceanography
- Early Years: Henry Stommel transitioned from astronomy at Yale to Oceanography at Woods Hole Oceanographic Institution (WHOI).
- Key Contributions: Henry Stommel made significant contributions to understanding ocean currents.
- Fluid Dynamics: Stommel's 1948 paper on "The westward intensification of wind-driven ocean currents" explained how the Earth's curvature, rotation, and fluid dynamics create stronger currents on the western boundaries of ocean basins.
- Global Ocean Circulation: His book The Gulf Stream detailed a decade of research on the Gulf Stream within the context of global circulation.
- Thermohaline Circulation: Stommel expanded his theory of global ocean circulation to include thermohaline effects, explaining how the formation of sea ice at the poles contributes to the density of water, thus generating a 'conveyor belt' effect.
- Established Research Station: In 1954, Stommel established the PANULIRUS research station in Bermuda for seawater sampling.
- National Recognition: Stommel was awarded the US National Medal of Science in 1989 for his work in oceanography.
Yang Chen-Ning: A Revolutionary Physicist
- Early Life and Education: Yang Chen-Ning received his PhD in nuclear physics from the University of Chicago, and continued to study subatomic particles at Princeton.
- Challenging Parity Conservation: Yang challenged the idea of Parity Conservation which stated that different directions in particle interactions are indistinguishable.
- Nobel Prize Winner: In 1956, Yang and Tsung-Dao Lee proposed that parity conservation was not always true and suggested an experiment was conducted by Chien-Shiung Wu which confirmed the theory. This achievement earned them the Nobel Prize in Physics in 1957.
- Further Achievements: Yang Chen - Ning made significant achievements in particle theory and published a groundbreaking paper in 1956 proving that conservation of parity was not always true, solidifying his contribution.
- Yang-Mills Theory: In 1954, Yang and Robert Mills proposed the Yang-Mills theory on elementary particles.
- Research Director: Yang became director of the theoretical physics research center at Stony Brook University in 1965.
- Key Timeline:
- 1922: Yang Chen-Ning was born.
- 1949: Yang moved to Princeton to study subatomic decay.
- 1954: Yang-Mills theory was proposed.
- 1956: Yang published his paper on the fallibility of parity conservation and collaborated with Tsung-Dao Lee.
- 1957: Yang and Lee were awarded the Nobel Prize.
- 1965: Yang became Research Director at Stony Brook University.
