Measurement in quantum mechanicsIn quantum physics, a measurement is the testing or manipulation of a physical system to yield a numerical result. A fundamental feature of quantum theory is that the predictions it makes are probabilistic. The procedure for finding a probability involves combining a quantum state, which mathematically describes a quantum system, with a mathematical representation of the measurement to be performed on that system. The formula for this calculation is known as the Born rule.
Como ConferenceThe International Congress of Physicists (Italian: Congresso internazionale dei fisici), better known as the Como Conference or the Volta Conference, was an international academic conference held from 11 to 27 September 1927, near Lake Como, Italy as part of a series of celebrations of the hundredth anniversary of the death of Alessandro Volta. This conference inspired the Volta Congresses held in Rome and organized since 1931.
Uncertainty principleThe uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known. In other words, the more accurately one property is measured, the less accurately the other property can be known.
Quantum mechanicsDescription of physical properties at the atomic and subatomic scaleWave functions of the electron in a hydrogen atom at different energy levels. Quantum mechanics cannot predict the exact location of a particle in space, only the probability of finding it at different locations.
Erwin SchrödingerErwin Rudolf Josef Alexander Schrödinger (12 August 1887 – 4 January 1961), sometimes anglicised as Schroedinger or Schrodinger, was an Austrian theoretical physicist who developed fundamental results in quantum theory. In particular, he is recognized for devising the Schrödinger equation, an equation that provides a way to calculate the wave function of a system and how it changes dynamically in time. He coined the term "quantum entanglement" in 1935.

Niels BohrDanish physicist (1885–1962)Niels Henrik David Bohr (; Danish:; 7 October 1885 – 18 November 1962) was a Danish theoretical physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. He was also a philosopher and a promoter of scientific research.Wave–particle dualityWave–particle duality is the concept in quantum mechanics that fundamental entities of the universe, like photons and electrons, exhibit particle or wave properties according to the experimental circumstances. It expresses the inability of the classical concepts such as particle or wave to fully describe the behavior of quantum objects.
Alessandro VoltaAlessandro Giuseppe Antonio Anastasio Volta (18 February 1745 – 5 March 1827) was an Italian chemist and physicist who was a pioneer of electricity and power, and is credited as the inventor of the electric battery and the discoverer of methane. He invented the voltaic pile in 1799, and reported the results of his experiments in a two-part letter to the president of the Royal Society in London, which was published in 1800.
ElectronThe electron (e, or β in nuclear reactions) is a subatomic particle whose electric charge is negative one elementary charge. It is an elementary particle contained in the matter that makes up the universe. All atoms are composed of electrons, as well as varying numbers protons and neutrons, but the electrons have almost 2,000 times less mass than the other two constituents.
Julian SchwingerJulian Seymour Schwinger (; February 12, 1918 – July 16, 1994) was an American theoretical physicist. He shared the 1965 Nobel Prize in Physics with Richard Feynman and Shin'ichirō Tomonaga "for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles". He developed a relativistically invariant perturbation theory, and renormalized QED to one loop order.PhysicsPhysics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. It is one of the most fundamental scientific disciplines. A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic disciplines.*As an Amazon Associate I earn from qualifying purchases.
