Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena.This is in contrast to experimental physics, which uses experimental tools to probe these phenomena.. The advancement of science generally depends on the interplay between experimental studies and …

In the Standard Model of particle physics, the Higgs mechanism is essential to explain the generation mechanism of the property "mass" for gauge bosons.Without the Higgs mechanism, all bosons (one of the two classes of particles, the other being fermions) would be considered massless, but measurements show that the W +, W −, and Z 0 bosons actually have relatively …

The SARK (Search and Rescue Knife) or NSAR (Navy Search and Rescue) is a folding knife designed by knifemaker Ernest Emerson for use as a search and rescue knife by the US military. It has a hawkbill with a blunt tip in order to cut free trapped victims without cutting them in the process. There is a variant with a pointed-tip designed for police, known as the P-SARK (Police …

Anatoli Petrovich Bugorski (Russian: Анатолий Петрович Бугорский), born 25 June 1942, is a retired Russian particle physicist.He is known for surviving a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his brain.

Leo Szilard (/ ˈ s ɪ l ɑːr d /; Hungarian: Szilárd Leó, pronounced [ˈsilaːrd ˈlɛoː]; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-American physicist and inventor.He conceived the nuclear chain reaction in 1933, patented the idea of a nuclear fission reactor in 1934, and in late 1939 wrote the letter for Albert Einstein's signature that resulted in the ...

In quantum mechanics, Schrödinger's cat is a thought experiment that illustrates a paradox of quantum superposition.In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of its fate being linked to a random subatomic event that may or may not occur.. This thought experiment was devised by physicist Erwin …

Ronald Lawrence Mallett (born March 30, 1945) is an American theoretical physicist, academic and author. He has been a faculty member of the University of Connecticut since 1975 and is best known for his scientific position on the possibility of time travel Early life and education. Mallett ...

In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevitably alters its state.In electronics the traditional term is probe …

The Big Bang theory describes how the universe expanded from an initial state of high density and temperature. It is the prevailing cosmological model explaining the evolution of the observable universe from the earliest known periods through its subsequent large-scale form. The model offers a comprehensive explanation for a broad range of observed phenomena, …
