Hertz wireless experiments (1887): Heinrich Hertz demonstrates free space electromagnetic waves, predicted by Maxwell's equations, with a simple dipole antenna and spark gap oscillator. Thomson's experiments with cathode rays (1897): J. J. Thomson's cathode ray tube experiments (discovers the electron and its negative charge).
Randonautica (a portmanteau of "random" + "nautica") is an app launched on February 22, 2020 founded by Auburn Salcedo and Joshua Lengfelder (/ lænɡfældɛr /). It randomly generates coordinates that enable the user to explore their local area and report on their findings. According to its creators, the app is "an attractor of strange things ...
Numerous experiments which were performed on human test subjects in the United States in the past are now considered to have been unethical, because they were performed without the knowledge or informed consent of the test subjects. [1] Such tests have been performed throughout American history, but have become significantly less frequent with ...
John D. Norton, a well-known philosopher of science, has noted that "a good thought experiment is a good argument; a bad thought experiment is a bad argument." [ 3 ] When effectively used, the irrelevant particulars that convert a straightforward argument into a thought experiment can act as "intuition pumps" that stimulate readers' ability to ...
In the design of experiments in statistics, the lady tasting tea is a randomized experiment devised by Ronald Fisher and reported in his book The Design of Experiments (1935). [1] The experiment is the original exposition of Fisher's notion of a null hypothesis, which is "never proved or established, but is possibly disproved, in the course of ...
1774 – Charles Mason: Conducts an experiment near the Scottish mountain of Schiehallion that attempts to measure the mean density of the Earth for the first time. Known as the Schiehallion experiment. 1796 – Edward Jenner: tests the first vaccine. 1798 – Henry Cavendish: Torsion bar experiment to measure Newton's gravitational constant.
In physics, the Ives–Stilwell experiment tested the contribution of relativistic time dilation to the Doppler shift of light. [ 1][ 2] The result was in agreement with the formula for the transverse Doppler effect and was the first direct, quantitative confirmation of the time dilation factor. Since then many Ives–Stilwell type experiments ...
