Bone char (Latin: carbo animalis) is a porous, black, granular material produced by charring animal bones. Its composition varies depending on how it is made; however, it consists mainly of tricalcium phosphate (or hydroxyapatite ) 57–80%, calcium carbonate 6–10% and carbon 7–10%. [ 1 ]
CMB spectral distortions are tiny departures of the average cosmic microwave background (CMB) frequency spectrum from the predictions given by a perfect black body.They can be produced by a number of standard and non-standard processes occurring at the early stages of cosmic history, and therefore allow us to probe the standard picture of cosmology.
Ru Yi Jing Gu Bang – Magical staff wielded by the Monkey King Sun Wukong in the Chinese classic novel, Journey to the West.; Some weapons in Chinese folklore do not, strictly speaking, have magical properties, but are forged with materials or methods that are unique in the context of the story.
The Gashadokuro is a spirit that takes the form of a giant skeleton made of the skulls of people who died in the battlefield or of starvation/famine (while the corpse becomes a gashadokuro, the spirit becomes a separate yōkai, known as hidarugami.), and is 10 or more meters tall.
Scientists have used the remains of some 500 people to create a series of “bone biographies” that provide a glimpse inside the ordinary lives of plague survivors of the English city of Cambridge.
Arthur C. Clarke, in the TV documentary 2001: The Making of a Myth, described the bone-to-satellite sequence in the film, saying "The bone goes up and turns into what is supposed to be an orbiting space bomb, a weapon in space. Well, that isn't made clear, we just assume it's some kind of space vehicle in a three-million-year jump cut".
1990 – FIRAS on the Cosmic Background Explorer (COBE) satellite measures the black body form of the CMB spectrum with exquisite precision, and shows that the microwave background has a nearly perfect black-body spectrum with T = 2.73 K and thereby strongly constrains the density of the intergalactic medium.
The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape our understanding of the cosmos.
