Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as experiments by Galileo Galilei, to more complicated ones, such as the Large Hadron Collider.

👉 Experimental physicist in the context of Luis Walter Alvarez
Luis Walter Alvarez (June 13, 1911 – September 1, 1988) was an American experimental physicist, inventor, and professor of Spanish descent who was awarded the Nobel Prize in Physics in 1968 for his discovery of resonance states in particle physics using the hydrogen bubble chamber. In 2007 the American Journal of Physics commented, "Luis Alvarez was one of the most brilliant and productive experimental physicists of the twentieth century."
After receiving his PhD from the University of Chicago in 1936, Alvarez went to work for Ernest Lawrence at the Radiation Laboratory at the University of California, Berkeley. Alvarez devised a set of experiments to observe K-electron capture in radioactive nuclei, predicted by the beta decay theory but never before observed. He produced tritium using the cyclotron and measured its lifetime. In collaboration with Felix Bloch, he measured the magnetic moment of the neutron.

Experimental physicist in the context of Victor Francis Hess
Victor Franz Hess (German: [ˈvɪktɔʁ ˈfʁants ˈhɛs]; 24 June 1883 – 17 December 1964) was an Austrian–American experimental physicist who shared the 1936 Nobel Prize in Physics with Carl David Anderson for his discovery of cosmic rays.
Experimental physicist in the context of James Chadwick
Sir James Chadwick (20 October 1891 – 24 July 1974) was a British experimental physicist who received the Nobel Prize in Physics in 1935 for his discovery of the neutron. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during World War II. He was knighted in Britain in 1945 for his achievements in nuclear physics.
Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics"). At Manchester, he continued to study under Rutherford until he was awarded his MSc in 1913. The same year, Chadwick was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851. He elected to study beta radiation under Hans Geiger in Berlin. Using Geiger's recently developed Geiger counter, Chadwick was able to demonstrate that beta radiation produced a continuous spectrum, and not discrete lines as had been thought. Still in Germany when World War I broke out in Europe, he spent the next four years in the Ruhleben internment camp.
Experimental physicist in the context of Wilhelm Röntgen
Wilhelm Conrad Röntgen (/ˈrɛntɡən, ˈrʌnt-/ RENT-guhn, RUHNT-; German: [ˈvɪlhɛlm ˈʁœntɡən] ; 27 March 1845 – 10 February 1923), sometimes transliterated as Roentgen, was a German experimental physicist who produced and detected electromagnetic radiation in a wavelength range known as X-rays. For this discovery, he became the first recipient of the Nobel Prize in Physics in 1901.
Experimental physicist in the context of Henri Becquerel
Antoine Henri Becquerel (/ˌbɛkəˈrɛl/ bek-uh-REL; French: [ɑ̃twan ɑ̃ʁi bɛkʁɛl]; 15 December 1852 – 25 August 1908) was a French experimental physicist who shared the 1903 Nobel Prize in Physics with Marie and Pierre Curie for his discovery of radioactivity.
Experimental physicist in the context of John Clarke (physicist)
John Clarke (born 10 February 1942) is a British experimental physicist and Professor Emeritus at the University of California, Berkeley. He is known for his various works on measurement devices based on superconductivity. Steven Girvin has called Clarke "the godfather of superconducting electronics".
In the 1980s, Clarke led a research team, that included John M. Martinis and Michel Devoret. Their discoveries in macroscopic quantum phenomena using the Josephson effect earned them the Nobel Prize in Physics in 2025.
Experimental physicist in the context of Robert Andrews Millikan
Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist who received the Nobel Prize in Physics in 1923 "for his work on the elementary charge of electricity and on the photoelectric effect."
As Chairman of the Executive Council of Caltech (the school's governing body at the time) from 1921 to 1945, Millikan helped to turn the school into one of the leading research institutions in the United States. He also served on the board of trustees for Science Service, now known as Society for Science & the Public, from 1921 to 1953.
Experimental physicist in the context of Hans Geiger
Johannes Wilhelm "Hans" Geiger (/ˈɡaɪɡər, ˈɡaɪɡə/ GYE-ger, GYE-guh; German: [ˈɡaɪɡɐ] ; 30 September 1882 – 24 September 1945) was a German experimental physicist. He is known as the inventor of the Geiger counter, a device used to detect ionizing radiation, and for carrying out the Rutherford scattering experiments, which led to the discovery of the atomic nucleus. He also performed the Bothe–Geiger coincidence experiment, which confirmed the conservation of energy in light-particle interactions.
He was the brother of meteorologist and climatologist Rudolf Geiger.
Experimental physicist in the context of Carl David Anderson
Carl David Anderson (September 3, 1905 – January 11, 1991) was an American experimental physicist who shared the 1936 Nobel Prize in Physics with Victor Hess for his discovery of the positron, which confirmed the existence of antimatter.
