Physics Wallah, or "PW", was founded in 2016 as a YouTube channel hosted by Alakh Pandey, an educator hailing from Prayagraj, Uttar Pradesh. The channel was initially focused on teaching the physics curriculum for the Joint Entrance Examinations (JEE), a popular entrance examination in India. [1] Due to Pandey's style of teaching [2] and the ...
Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.

In theoretical physics, quantum chromodynamics ( QCD) is the study of the strong interaction between quarks mediated by gluons. Quarks are fundamental particles that make up composite hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory, with symmetry group SU (3).
The Nobel Prize in Physics ( Swedish: Nobelpriset i fysik) is an annual award given by the Royal Swedish Academy of Sciences for those who have made the most outstanding contributions to mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901, the others being ...
A wormhole is a hypothetical structure connecting disparate points in spacetime, and is based on a special solution of the Einstein field equations. [1] A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are consistent with the general ...
Wave–particle duality is the concept in quantum mechanics that quantum entities exhibit particle or wave properties according to the experimental circumstances. [1] : 59 It expresses the inability of the classical concepts such as particle or wave to fully describe the behavior of quantum objects. [2] : . III:1-1 During the 19th and early ...
The discoveries of the neutron and positron in 1932 were the start of the discoveries of many new particles. Muons were discovered in 1936. Pions and kaons were discovered in 1947, while lambda particles were discovered in 1950. Throughout the 1950s and 1960s, a large number of particles called hadrons were discovered.
