Technical reports used to be made available in print, but are now more commonly published electronically (typically in PDF), whether on the Internet or on the originating organization's intranet. Several schemes have been proposed or are in use to uniquely identify either an entire report series or an individual report:
This result was presented in opposition to caloric theory (1798). Humphry Davy uses electrolysis to isolate elemental potassium, sodium, calcium, strontium, barium, magnesium, and chlorine (1807–1810). Joseph Louis Gay-Lussac studies reactions among gases and determines that their volumes combine chemically in simple integer ratios (1809).
John August List (born September 25, 1968) is an American economist known for his work in establishing field experiments as a tool in empirical economic analysis. Since 2016, he has served as the Kenneth C. Griffin Distinguished Service Professor of Economics at the University of Chicago, where he was Chairman of the Department of Economics from 2012 to 2018.

This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
Chien-Shiung Wu, after whom the Wu experiment is named, designed the experiment and led the team that carried out the test of the conservation of parity in 1956.. The Wu experiment was a particle and nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low Temperature Group of the US National Bureau of Standards.

Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
Wheeler's cosmic interferometer uses a distant quasar with two paths to equipment on Earth, one direct and one by gravitational lensing. After [2]. In an attempt to avoid destroying normal ideas of cause and effect, some theoreticians [who?] suggested that information about whether there was or was not a second beam-splitter installed could somehow be transmitted from the end point of the ...
This increases the speed and efficiency of gathering experimental results and reduces the costs of implementing the experiment. Another cutting-edge technique in field experiments is the use of the multi armed bandit design, [ 11 ] including similar adaptive designs on experiments with variable outcomes and variable treatments over time.
