Study Notes
World War II Research Funding
- Governments increased funding for research during WWII, hoping to gain tactical advantages
- Intense competition among scientists led to new discoveries, impacting both military and civilian life after the war
- Research continued after the war ended
Wolfgang Pauli
- Austrian-born Swiss and American theoretical physicist
- Known for his work on atomic structure and the Pauli exclusion principle
- This principle states no two electrons in an atom can occupy the same quantum state simultaneously
- Also created a model that explained the properties of metals
- He was the first to propose existence of a subatomic particle called the neutrino
- Awarded the Nobel Prize in Physics in 1945.
Theodosius Dobzhansky
- Russian population geneticist
- A central figure in evolutionary biology
- Born in Ukraine, emigrated to the US in 1927
- Extensive work with fruit flies helped bridge the gap between genetics and evolution
- Showed mutations created genetic diversity, providing the raw material for natural selection
- Helped reconcile genetic findings with Darwin's theory of evolution
Howard Aiken
- American electrical engineer
- Built the Harvard Mark I computer in 1944
- A part-electric, part-mechanical computer used during WWII
- Demonstrated programmable machines could solve large-scale problems automatically
- Helped pave the way for modern computers, working alongside Grace Hopper
- Helped develop computer programming methods
Werner Heisenberg
- Born in Würzburg, Germany, in 1901
- Studied mathematics and physics at universities in Munich and Göttingen.
- Met his future collaborator Niels Bohr in Göttingen in 1922
- Known for his work on the Copenhagen interpretation (quantum systems governed by probability rules)
- Contributed to the uncertainty principle and quantum field theory
- Developed his own theory of antimatter
- Received the 1932 Nobel Prize in Physics for his work on quantum mechanics (youngest recipient)
Linus Pauling
- Chemist born in Portland, Oregon
- Winner of two Nobel Prizes—one in Chemistry and one for Peace
- Contributed to quantum mechanics in early chemistry
- Influential chemistry textbook author, "The Nature of the Chemical Bond"
- Developed rules for determining the structure of ionic crystals
- Explained atomic orbitals in covalent compounds
- Described how atomic orbitals combine to form molecular orbitals
Kathleen Lonsdale
- Worked under William Henry Bragg at the Royal Institution, London
- Developed X-ray techniques for studying chemical compound structures
- Found that carbon atoms in benzene are arranged in a hexagonal ring
- Applied X-ray crystallography to study bladder stones and drugs
- Became a fellow of the Royal Society in 1945, one of two women elected at the time.
John von Neumann
- Brilliant Hungarian-born mathematician
- Worked on early high-speed electronic digital computers
- Collaborated with American meteorologist Jule Charney to develop computer-based weather prediction methods.
- Developed a model for modern computers that could store both data and programs (Von Neumann architecture)
Wendell Stanley
- Born in Indiana
- Determined the molecular structure of viruses using X-ray diffraction
- Shared the 1946 Nobel Prize in Chemistry for his research on the tobacco mosaic virus
- Provided insights into viruses as causes of infectious diseases during WWII.
- Critically contributed to developing a vaccine against influenza
- Played a part in enabling the development of a polio vaccine.
