A Boy and His Atom is a 2013 stop-motion animated short film released on YouTube by IBM Research. One minute in length, it was made by moving carbon monoxide molecules with a scanning tunneling microscope , a device that magnifies them 100 million times.
HIARCS is a proprietary UCI chess engine developed by Mark Uniacke. [1] Its name is an acronym standing for higher intelligence auto-response chess system.Because Hiarcs is written portable in C, it is available on multiple platforms such as Pocket PC, Palm OS, PDAs, iOS, Microsoft Windows and Mac OS X.
A Is for Atom (1953) is a 14-minute promotional animated short documentary film created by John Sutherland and sponsored by General Electric (GE). The short documentary, which is now in the public domain, explains what an atom is, how nuclear energy is released from certain kinds of atoms, the peacetime uses of nuclear power, and the by-products of nuclear fission.
A process involving virtual particles can be described by a schematic representation known as a Feynman diagram, in which virtual particles are represented by internal lines. [2] [3] Virtual particles do not necessarily carry the same mass as the corresponding ordinary particle, although they always conserve energy and momentum. The closer its ...
Diagram showing the process of electron–positron pair production. In reality the produced pair are nearly collinear. The black dot labelled 'Z' represents an adjacent atom, with atomic number Z. For photons with high photon energy (MeV scale and higher), pair production is the dominant mode of photon interaction with matter.
Virtual photons are responsible for Lamb shift, which is a small shift in the energy levels of hydrogen atoms caused by the interaction of the atom with virtual photons in the vacuum. They are also responsible for the Casimir effect , which is the phenomenon of two uncharged metallic plates being attracted to each other due to the presence of ...
Uniacke was released as part of a leniency policy and when his career prospered, he acquired the land for his estate. Construction of the house began in 1813 and was completed in 1818. Uniacke had a town house in Halifax, but spent most of his time living and entertaining at the estate until his death at the house in 1830.
An atom interferometer uses the wave-like nature of atoms in order to produce interference. In atom interferometers, the roles of matter and light are reversed compared to the laser based interferometers, i.e. the beam splitter and mirrors are lasers while the source emits matter waves (the atoms) rather than light.
