A green lion consuming the Sun is a common alchemical image and is seen in texts such as the Rosary of the Philosophers. The symbol is a metaphor for aqua regia (the green lion) consuming matter (the Sun), gold. In alchemical and Hermetic traditions, suns are used to symbolize a variety of concepts, much like the Sun in astrology.
The list starts with 🜚 for gold and has early conventions that would later change: here ☿ is tin and ♃ electrum; ☾ is silver but ☽ is mercury. Many of the 'symbols' are simply abbreviations of the Greek word or phrase. View the files on Commons for the list of symbols. [citation needed]

41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Simplified geodynamo models have shown relationships between the dynamo number (determined by variance in rotational rates in the outer core and mirror-asymmetric convection (e.g. when convection favors one direction in the north and the other in the south)) and magnetic pole reversals as well as found similarities between the geodynamo and the ...
Gold cycling starts with the microbial weathering of gold-bearing rocks and minerals which mobilizes gold in the environment via release of elemental gold and solubilization. [ 2 ] [ 3 ] The Witwatersrand gold deposits host approximately 30% of the world's gold resources, a large proportion of which is directly associated with organic carbon ...
In the 1928 book The Nature of the Physical World, which helped to popularize the concept, Eddington stated: . Let us draw an arrow arbitrarily. If as we follow the arrow we find more and more of the random element in the state of the world, then the arrow is pointing towards the future; if the random element decreases the arrow points towards the past.
The precise nature of this remaining fraction is an area of active research. An active search from Earth orbit for anti-alpha particles as of 2019 [ 12 ] had found no unequivocal evidence. Upon striking the atmosphere, cosmic rays violently burst atoms into other bits of matter, producing large amounts of pions and muons (produced from the ...
