Genaille–Lucas rulers (also known as Genaille's rods) are an arithmetic tool invented by Henri Genaille, a French railway engineer, in 1891. The device is a variant of Napier's bones . By representing the carry graphically, the user can read off the results of simple multiplication problems directly, with no intermediate mental calculations .
Since 2 represents 20, all numbers in that scale are multiplied by 10. Thus, any answer in the second set of numbers is multiplied by 100. Since 8.8 in the top scale represents 88, the answer must additionally be multiplied by 10. The answer directly reads 1.76. Multiply by 100 and then by 10 to get the actual answer: 1,760.
The Bosporan kings were the rulers of the Bosporan Kingdom, an ancient Hellenistic Greco-Scythian state centered on the Kerch Strait (the Cimmerian Bosporus) and ruled from the city of Panticapaeum. Panticapaeum was founded in the 7th or 6th century BC; the earliest known king of the Bosporus is Archaeanax , who seized control of the city c ...
It has been proved that no perfect Golomb ruler exists for five or more marks. [3] A Golomb ruler is optimal if no shorter Golomb ruler of the same order exists. Creating Golomb rulers is easy, but proving the optimal Golomb ruler (or rulers) for a specified order is computationally very challenging.
A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale. In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
Gomitra II and Brahmamitra especially are known for their large number of coins, which is not so much the case for other rulers. [4] In the archaeological excavations of Sonkh, near Mathura, archaeological levels of the Mitra rulers were identified. [8] Coins of the Mitra dynasty were found in Sonkh especially, in layers dated to about 150–50 ...
See P and DI scales in detail image. In slide rule terminology, "folded" means a scale that starts and finishes at values offset from a power of 10 . Often folded scales start at π but may be extended lengthways to, say, 3.0 and 35.0.
