    Results of the Frisch–Smith experiment. Curves computed for M N e w t o n {\displaystyle M_{\mathrm {Newton} }} and M S R {\displaystyle M_{\mathrm {SR} }} . If no time dilation exists, then those muons should decay in the upper regions of the atmosphere, however, as a consequence of time dilation they are present in considerable amount also ...

    en.wikipedia.org/wiki/Periodic_Videos

    The Periodic Table of Videos has filmed at least one video for each of the 118 elements (from hydrogen to oganesson). [13] They have also filmed several videos that discuss molecules such as D 2 O (heavy water) [14] and sulfuric acid. [15] Also filmed are "Chem definitions" that provide an explanation to words that are used in chemistry.

    en.wikipedia.org/wiki/Bunker_experiment

    Many participants found the idea of living in a bunker without time cues daunting, but most ended up enjoying the experiment. [1] Aschoff was the first test subject, with Rütger Wever observing. [2] The experiment began in 1966 and continued until the early 1980s. [1] As of 2013, the bunker was still in existence, although quite dilapidated. [9]

    en.wikipedia.org/wiki/Time_crystal

    The time crystals that are experimentally realized show discrete time-translation symmetry breaking, not the continuous one: they are periodically driven systems oscillating at a fraction of the frequency of the driving force. (According to Philip Ball, DTC are so-called because "their periodicity is a discrete, integer multiple of the driving ...

    Experiments conducted since then have put upper bounds on their time-dependence. This concerns the fine-structure constant, the gravitational constant and the proton-to-electron mass ratio specifically, for all of which there are ongoing efforts to improve tests on their time-dependence.

  9. List of neutrino experiments - Wikipedia

    en.wikipedia.org/wiki/List_of_neutrino_experiments

    Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
