Fresh Paint originated from a Microsoft Research project known as Project Gustav, [3] an endeavor to reproduce the behavior of physical oil paint on a digital medium. To push the boundaries of simulating oil on a digital medium, the research team created a physics model that precisely replicated on a screen what would happen in the real world if you combined oil, a surface and a tool such as a ...

After the end of the nuclear arms race, the demand for lithium decreased and the sale of department of energy stockpiles on the open market further reduced prices. [92] In the mid-1990s, several companies started to isolate lithium from brine which proved to be a less expensive option than underground or open-pit mining. Most of the mines ...
The price is high and varying (see table). Illustrative factors that affect the price include oversupply of Ir crucibles [79] [81] and changes in LED technology. [82] Platinum metals occur together as dilute ores. Iridium is one of the rarer platinum metals: for every 190 tonnes of platinum obtained from ores, only 7.5 tonnes of iridium is ...

Book It! was conceived in 1984 during a ...
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of Camellia sinensis, an evergreen shrub native to East Asia which probably originated in the borderlands of south-western China and northern Myanmar. [3] [4] [5] Tea is also made, but rarely, from the leaves of Camellia taliensis.
In a uniform strand of pearls, all pearls are classified as the same size, but actually fall in a range. A uniform strand of akoya pearls, for example, will measure within 0.5 mm. So a strand will never be 7 mm, but will be 6.5–7 mm. Freshwater pearls, Tahitian pearls, and South Sea pearls all measure to a full millimeter when considered uniform.
Fluorine has two solid forms, α- and β-fluorine. The latter crystallizes at −220 °C (−364.0 °F) and is transparent and soft, with the same disordered cubic structure of freshly crystallized solid oxygen, [44] [note 3] unlike the orthorhombic systems of other solid halogens.
