Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is a tasteless, odourless, strong, and brittle solid that is transparent in colour, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the ...
Aether: Final Fantasy XIV: In the MMORPG Final Fantasy XIV, Aether is one of the main elements of life and magic in the world. [12] [13] Magic: The Gathering: Aether (previously spelled Æther) is the main type of energy filling the blind eternities in the Magic: The Gathering multiverse, though it can also appear in variable quantities within ...
The luminiferous aether: it was hypothesised that the Earth moves through a "medium" of aether that carries light. Luminiferous aether or ether[ 1 ] ( luminiferous meaning 'light-bearing') was the postulated medium for the propagation of light. [ 2 ] It was invoked to explain the ability of the apparently wave -based light to propagate through ...

The philosopher's stone[ a] is a mythic alchemical substance capable of turning base metals such as mercury into gold or silver [ b]; it was also known as "the tincture" and "the powder".

Classical elements. According to ancient and medieval science, aether ( / ˈiːθər /, alternative spellings include æther, aither, and ether ), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. [ 1] The concept of aether was used in several theories to ...
These beta particles would be used by Thomson to probe atoms to find evidence for his atomic theory. The other form of radiation critical to this era of atomic models was alpha particles. Heavier and slower than beta particles, these would be the key tool used by Rutherford to find evidence against Thomson's model.
Timeline of luminiferous aether. The timeline of luminiferous aether (light-bearing aether) or ether as a medium for propagating electromagnetic radiation begins in the 18th century. The aether was assumed to exist for much of the 19th century—until the Michelson–Morley experiment returned its famous null result.
To give provisional names to his predicted elements, Dmitri Mendeleev used the prefixes eka- / ˈ iː k ə-/, [note 1] dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, [3] depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table.
