    Study Notes

    Richard Feynman

    • Feynman was a physicist known for making complex physics theories engaging and entertaining.
    • He participated in the Manhattan Project, the Allied nuclear-weapons program.
    • He was influential in developing quantum electrodynamics (QED), a theory of light and matter, and used diagrams to explain the interactions of light and matter.
    • Feynman's diagrams helped develop a mathematical model to calculate the probabilities of quantum events.
    • He proposed the concept of "partons," a precursor to quarks.
    • He was involved in investigating the Challenger space shuttle disaster.

    Murray Gell-Mann

    • Murray Gell-Mann, a theoretical physicist, developed a system to classify subatomic particles, achieving high accuracy in his predictions.
    • He proposed a model dividing subatomic particles into "fermions" (building blocks of matter) and "bosons" (force carriers).
    • Gell-Mann's model introduced "quarks" as hypothetical fundamental units of matter.
    • The standard model, based on Gell-Mann's work, later earned him the 1969 Nobel Prize in Physics.

    Henry Stommel

    • Stommel was a US oceanographer who made significant contributions to understanding ocean currents.
    • He studied astronomy before focusing on oceanography.
    • He published a pivotal paper on "The westward intensification of wind-driven ocean currents" in 1948.
    • Stommel established the PANULIRUS research station in Bermuda for collecting data.
    • He published "The Gulf Stream" in 1958, highlighting its global context and dynamics.
    • Stommel developed theories on thermohaline effects, demonstrating how variations in temperature and salinity drive the "Great Ocean Conveyor Belt," a key part in global ocean circulation.
    • He was awarded the National Medal of Science in 1989 for his work on ocean currents.
