... -The color of the light emitted depends on which energy level they “fall back from”: -high energy (outer): has short wave length: violets -low energy (inner): has long wave length: reds -Elements will emit their own different patterns of colors called a spectrum: fire works? -Every element has its o ...

... then resurfaced. Between 1900 and 1930 quantum mechanics, the theory that described microscopic phenomena, had become fairly well developed. The Dirac theory of the hydrogen atom electron (1928) led to the discovery of the positron, the antiparticle of the electron, in 1932. By the year 1932 it had ...

Compact Muon Solenoid
The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.CMS is 21.6 metres long, 15 metres in diameter, and weighs about 14,000 tonnes. Approximately 3,800 people, representing 199 scientific institutes and 43 countries, form the CMS collaboration who built and now operate the detector. It is located in an underground cavern at Cessy in France, just across the border from Geneva. In July 2012, along with ATLAS, CMS tentatively discovered the Higgs Boson.
