This video about the largest and most efficient engine on earth was striking to me in its pleasant and oddly calming delivery, not to mention the fascinating story within. Dunno - wanted to share. The Biggest Engine on Earth Is Four Stories Tall — And It Turns Just 102 Times a Minute - https://www.youtube.com/watch?v=2Y09r_4O6Hc #engineering #science #physics #engines #shipping #documentary #video #YouTube #motors #cargoships #ships

Important note about ideal amplifiers in electronics >Amplifier is the generic term used to describe a circuit which produces and increased version of its input signal. However as we will see in this introduction to the amplifier tutorial, not all amplifier circuits are the same as they are classified according to their circuit configurations and modes of operation. >In “Electronics”, small signal amplifiers are commonly used devices as they have the ability to amplify a relatively small input signal. For example from a Sensor such as a photo-device, into a much larger output signal to drive a relay, lamp or loudspeaker for example. https://www.electronics-tutorials.ws/amplifier/amp_1.html #Electronics #electrónica #Physics #Mathematics #Chemistry #Lineair #Algebra

Liquid is a state of matter with a definite volume but no fixed shape. When confined in a container and subject to a force such as gravity, liquids will adapt to the internal shape of the container in the direction of the force.[note 1] Liquids are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Liquids are a form of condensed matter alongside solids, and a form of fluid alongside gases. https://en.wikipedia.org/wiki/Liquid #physics #caturday #caturdayeveryday

I asked an #AI model If, in a hypothetical #universe, the speed of #light is not constant & #energy varies with 'c' If we differentiate E=mc² twice with respect to c, what would be the consequences? It said this would destroy the universal causal structure. Stars would collapse, & many other things would happen. No #physicist could explain these outcomes Leaving hostility aside, AI is just a tool. It's up to you whether you use it for good or bad #stem #MultipleDomain #science #physics

Update of our paper is now available on arXiv! 📄 "The bosonic Hubbard model on a three-dimensional flat band lattice" (arXiv:2604.19703) 🔗 http://arxiv.org/abs/2604.19703 We present a frustration-free bosonic Hubbard model on a 3D flat band lattice, the line graph of the cubic lattice. For the first time (to our knowledge), we observe subextensive ground state entropy in a bosonic lattice model. The result is related to the number of 4-cycle decompositions of the cubic lattice, for which we derive upper and lower bounds. Co-authored with Leon Haag-Fank. Looking forward to your thoughts and discussions! #Physics #Math #CondensedMatter #OpenScience #arXiv

Texture is one of the important factors that control friction and transfer layer formation during sliding. Considerable efforts have been made to study the influence of surface texture on friction and wear during sliding conditions. Surface textures can be isotropic or anisotropic. Sometimes, stick-slip friction phenomena can be observed during sliding, depending on surface texture. https://en.wikipedia.org/wiki/Surface_finish #texture #physics #arts

I know for a fact, now, that there is no such thing as a photon: https://michelson-morley.crudfactory.com/#_there_is_no_such_thing_as_a_photon Take it or leave it as you wish. I do not try to force belief on anyone, and I am not a professor who controls your grade or whether you get granted a PhD. #physics #science

Almost every sensitive radiation detector built since 1945 relies on steel salvaged from ships that sank before the first nuclear test, because everything smelted after that date carries a faint trace of the bomb era in its structure, and the supply of pre-war wrecks is finite. https://spacedaily.com/t-low-background-steel-shipwreck-radiation-detectors/ #science #physics

A proposed White House rule would give political appointees unprecedented control over scientific funding. One physicist, who helped discover the Higgs boson, the so-called “God particle,” explains how the move would’ve stifled that breakthrough. https://www.propublica.org/article/federal-science-grants-russell-vought-omb?utm_source=mastodon&utm_medium=social&utm_campaign=mastodon-post #News #WhiteHouse #Trump #Science #Physics #Research #Funding #Academia

Ok, I was fully prepared for this to be completely made up...and yet... it is true. Fritz #Zwicky really did coin the phrases "dark matter" and "spherical bastards". What a froopy dude! #physics #language #semantics #sphericalbastards #darkmatter #astrophysics

A gamma ray, also known as gamma radiation (symbol γ), is a penetrating form of electromagnetic radiation arising from high-energy interactions like the radioactive decay of atomic nuclei or astronomical events like solar flares. Lower energy gamma radiation overlaps the upper end of X-ray radiation; they are distinguished by their different origins. Gamma ray photons have photon energy at the lower end from 104 eV to 107 eV; ultra-high-energy gamma rays have energies over 1014 eV.[1]: 12  Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900, he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power. https://en.wikipedia.org/wiki/Gamma_ray #physics #nuclearphysics #caturday #caturdayeveryday
