Study Notes
Murray Gell-Mann
- Murray Gell-Mann, a theoretical physicist, made significant contributions to particle physics.
- He classified subatomic particles into fermions (building blocks of matter) and bosons (force carriers).
- He introduced the concept of "quarks", a type of fermion that combines to form hadrons (protons & neutrons).
- His model of particle classification later became the "Standard Model" and he won the Nobel Prize in Physics in 1969.
- Gell-Mann developed a system to accurately describe particle interactions to 15 decimal places.
Richard Feynman
- Feynman was a physicist who advanced our understanding of quantum electrodynamics (QED).
- He simplified complex equations using visual diagrams called Feynman diagrams.
- The diagrams represent the movements of particles in time and space, even backwards.
- Feynman's work led to a clearer understanding of QED and calculations of probabilities of particle events.
- His contributions to QED made it one of the most successful theories in physics.
- He made contributions to other areas of physics like nanotechnology, superfluidity and quantum computing.
- He also investigated the Challenger space shuttle disaster.

- He published his book The Gulf Stream, providing a decade-long study of the current in 1958.
- He developed theories about global ocean circulations, encompassing temperature and salinity variations.
- He played a crucial role in leading two global oceanographic studies.

McCulloch and Till's Breakthroughs in Bone Marrow Research
- McCulloch and Till's research in 1961 uncovered stem cells with the unique potential to differentiate into various specialized cells and self-renew.
- They observed unusual nodules on mice spleens after bone marrow transplants.
- They determined that each nodule originated from a single cell, creating a clone of cells.
- These clones, "colony-forming units," were surprisingly diverse, comprising all three main blood cell types.
James Till
- James Till was a physicist who focused on cancer research using radiation treatments.
- He made the groundbreaking discovery of stem cells with Ernest McCulloch.
- He declined an assistant professorship at Yale University in 1957.
- He became a Fellow of the Royal Society of Canada in 1969.
