Quantum computing is not simple to understand. A good starting place is some of the ideas in quantum mechanics since they are fundamental to quantum computing. This is an introduction to a series of posts on stuff related to quantum quantum mechanics and quantum computing. Definition of “quantum” An amount or quantity of something A […]
Enrico Fermi was born in Rome, Italy in 1901 and was known as a physicist who helped to create the first nuclear reactor. He worked on the project known as “Chicago Pile-1” which created the first controlled nuclear fission reaction. Subatomic particles that follow Fermi-Dirac statistics are called “fermions” in his honor. At Los Alamos, […]
George Lemaitre was born in 1894 in Belgium and was an astronomer and physicist who became known for promoting the theory of an expanding universe. In 1927, he published an article titled, “A Homogeneous Universe of Constant Mass and Increasing Radius accounting for the Radial Velocity of Extra Galactic Nebulae”, which used the relativity equations […]
Shen Kuo was born in 1031 in Qiantang (Hangzhou today) in Eastern China. He excelled in the fields of astronomy, physics, chemistry, geology, medicine, literature, engineering, and was also known as a diplomat and expert at military strategy. Both his knowledge and assorted skills were encyclopedic. PRECURSOR: -0325 – Euclid 0220 – Ma Jun 0283 […]
FOUR ELEMENTS Plato defined four basic elements as earth, water, air, and fire. In his analysis of geometry he defined five regular solids. He paired up the four elements with four of the five regular solids and this suggested to him that there might be another element. He assigned earth to the cube, water to […]
Quarks are the pieces that combine to make protons and neutrons and other composite components known as hadrons. There are two main “families” of hadrons, categorized by how the quarks combine. Baryons, such as protons and neutrons, are composed of three quarks. Mesons are composed of a quark and an anti-quark, and are involved in […]
Leo Szilard was born in Budapest, Hungary in 1898, and was a physicist. He is mostly known for creating the idea of a chain reaction and held a patent with Enrico Fermi for the nuclear reactor. He also invented the linear particle accelerator, and created ideas for the cyclotron and electron microscope. PRECURSOR: 1831 – […]
Born around 1170 in Suffolk, England, Robert Grosseteste was a student of many subjects who became a bishop in the Church of England. He was proficient in the Greek language, translating many works into Latin. He performed experiments with light and mirrors and made lenses from bowls filled with water to study refraction. His investigation […]

A recent article explored half vortex rings in water, that showed a fairly stable pair of vortices on the surface of the water – see: Vortex – Physics – Dimensions Sunspots are often described as pairs of vortices. Perhaps they are vortex rings in the plasma of the sun that we can observe when they […]
