Afshar Experiment Afshar Experiment gives information about which of two paths a photon takes through the apparatus while simultaneously allowing interference between the two paths to be…
Time Dilation Time Dilation turns out that as an object moves with relativistic speeds a “strange” thing seems to happen to its time as observed by “us”…
Supplee’s Paradox Supplee’s Paradox is about whether a relativistic projectile, subject to uniform gravitational acceleration, would float or sink underwater. It arises when considering the buoyant force…
Ladder Paradox Ladder Paradox is a medieval knight riding a charger carrying a lance in place of the ladder, but honestly any long horizontal object will do…
Ehrenfest Paradox Ehrenfest Paradox is the retardation in the transmission of centripetal accelerations. It is also plays an important role in time desynchronization. It has been deepened…
Twin Paradox Twin Paradox is that one of a pair of twins leaves on a high speed space journey during which he travels at a large fraction…
Tests of General Relativity Einstein proposed three tests of his own tests of general relativity when he first published it in 1915: the precession of Mercury’s orbit, the bending…
Hafele–Keating Experiment Hafele–Keating Experiment is so tampered with that it could be considered fraudulent. It was a test of the theory of relativity. In October 1971, Hafele…
Franck–Hertz Experiment Franck–Hertz Experiment is demonstrated the existence of excited states in mercury atoms, helping to confirm the quantum theory which predicted that electrons occupied only discrete,…
Double-Slit Experiment Double-Slit Experiment belongs to a general class of “double path” experiments, in which a wave is split into two separate waves that later combine into…
Davisson-Germer Experiment Davisson-Germer Experiment is the first measurement of the wavelengths of electrons. It is a physics experiment conducted by American physicists Clinton Davisson and Lester Germer…
Cavendish Experiment Cavendish Experiment used a torsion balance device to attract lead balls together, measuring the torque on a wire and equating it to the gravitational force…
