In chess, a relative value (or point value) is a standard value conventionally assigned to each piece. Piece valuations have no role in the rules of chess but are useful as an aid to evaluating a position. The best-known system assigns 1 point to a pawn, 3 points to a knight or bishop, 5 points to a rook and 9 points to a queen. Valuation ...
Otis Carter Formby King (1876–1944) was an electrical engineer [1] in London who invented and produced a cylindrical slide rule with helical scales, primarily for business uses initially. The product was named Otis King's Patent Calculator , and was manufactured and sold by Carbic Ltd. in London from about 1922 to about 1972.
Purdy gave the value as 1½ points in the opening and increasing to 2 points in the endgame. In the middlegame the value would be closer to 1½ than to 2. [4] Edmar Mednis gave the value as 1½ in the endgame. [5] [6] Max Euwe put the value at 1½ in the middlegame and said that two pawns are more than sufficient compensation for the exchange. [7]
In the Zork series of games, the Great Underground Empire has its own system of measurements, the most frequently referenced of which is the bloit. Defined as the distance the king's favorite pet can run in one hour (spoofing a popular legend about the history of the foot), the length of the bloit varies dramatically, but the one canonical conversion to real-world units puts it at ...
There are two main types of cylindrical slide rules: those with helical scales such as the Fuller calculator, the Otis King and the Bygrave slide rule, and those with bars, such as the Thacher and some Loga models. In either case, the advantage is a much longer scale, and hence potentially greater precision, than afforded by a straight or ...
The dragon king concept raises many questions about how one can deal with risk. Of course, if possible, exposure to large risks should be avoided (often referred to as the "black swan approach"). However, in many developments, exposure to risk is a necessity, and a trade-off between risk and return needs to be navigated.
A stock market simulator is computer software that reproduces behavior and features of a stock market, so that a user may practice trading stocks without financial risk. Paper trading , sometimes also called "virtual stock trading", is a simulated trading process in which would-be investors can practice investing without committing money.
Scale armour is armour in which the individual scales are sewn or laced to a backing by one or more edges and arranged in overlapping rows resembling the scales of a fish/reptile or roofing tiles. [3] The scales are usually assembled and strapped by lacing or rivets. Lorica squamata is an ancient Roman armour of this type. [1]
