Study Notes
Wilhelm Conrad Röntgen
- German physicist who discovered X-rays in 1895
- X-rays emitted from electrically charged vacuum tubes
- X-rays could penetrate human skin but were stopped by metal and bone
- Won the first Nobel Prize in Physics in 1901 for his discovery
- Also contributed to mechanics, heat, and electricity
Ivan Pavlov
- Russian-born physiologist who abandoned a religious career to pursue science
- Studied digestive secretions of dogs
- Discovered classical conditioning, also known as Pavlovian conditioning
- Classical Conditioning: dogs could learn to associate food with the sound of a bell, and would salivate in response to the bell alone
- Won the Nobel Prize in Physiology or Medicine in 1904
Kitasato Shibasaburo
- Japanese physician and bacteriologist
- Developed serum therapy for tetanus and diphtheria
- Discovered that tetanus serum could confer immunity to animals
- This principle was later applied to diphtheria protection
Jules Henri Poincaré
- French mathematical physicist
- Investigated the stability of the solar system
- His work led to the discovery of chaos theory: small changes in initial conditions can lead to large and unpredictable outcomes in a system
- His research highlighted the complex behavior of systems that appear stable
- Also conducted research in electromagnetism
J.J. Thomson
- English physicist who studied atomic structure
- Identified "corpuscles" (later called electrons) using a cathode ray tube
- Found that electrons were negatively charged and lighter than a hydrogen atom
- Proposed the "plum pudding" model of the atom: positive charge with negatively charged electrons scattered within
- This discovery revolutionized atomic theory and electricity
- Identified isotopes, elements with various atomic forms
Svante Arrhenius
- Swedish physicist who studied at the University of Uppsala
- Contributed to the understanding of the role of ions in chemical processes
