Per Square Mile Magnesium injection cycle Magnesium Injection Cycle (MAGIC) is an engine design currently under development by Mitsubishi Corporation and the Tokyo Institute of Technology which uses magnesium and water to generate power.[1][2][3] The engine also makes use of solar-powered lasers. Overview[edit] Output[edit] Despite its small dimensions (approx. 5 cm in diameter and 13.5 cm in height), the engine can generate a heat output of several tens of kW from which power is obtained.[3] The engine is aimed to be used in cogeneration, automobiles, ships, and many other areas. Personnel[edit] The engine development was led by Professor Takashi Yabe with the help of Professor Ikuta and others of Tokyo Institute of Technology with the cooperation of Ono Denki Seisakusho, K.K., a precision manufacturer located in Shinagawa, Tokyo.

The Museum of Mathematics Is the Universe a Holographic Reality? - Global One TV The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. Aspect and his team discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. University of London physicist David Bohm, for example, believes Aspect's findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram. To understand why Bohm makes this startling assertion, one must first understand a little about holograms. The three-dimensionality of such images is not the only remarkable characteristic of holograms. The "whole in every part" nature of a hologram provides us with an entirely new way of understanding organization and order. This insight suggested to Bohm another way of understanding Aspect's discovery.
History of elementary algebra As a branch of mathematics, algebra emerged at the end of 16th century, with the work of François Viète. Algebra can essentially be considered as doing computations similar to that of arithmetic with non-numerical mathematical objects. However, until the 19th century, algebra consisted essentially of the theory of equations. This article describes the history of the theory of equations, called here "algebra", from the origins to the emergence of algebra as a separate area of mathematics. Etymology[edit] Stages of algebra[edit] Algebraic expression[edit] Algebra did not always make use of the symbolism that is now ubiquitous in mathematics, rather, it went through three distinct stages. Rhetorical algebra, where equations are written in full sentences. As important as the symbolism, or lack thereof, that was used in algebra was the degree of the equations that were used. where p and q are positive. , with p and q positive, have no positive roots.[2] Conceptual stages[edit] and is, Data[edit]

Trachtenberg system The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. It was developed by the Russian Jewish engineer Jakow Trachtenberg in order to keep his mind occupied while being held in a Nazi concentration camp. The rest of this article presents some methods devised by Trachtenberg. The chapter on addition demonstrates an effective method of checking calculations that can also be applied to multiplication. General multiplication[edit] The method for general multiplication is a method to achieve multiplications with low space complexity, i.e. as few temporary results as possible to be kept in memory. times the next-to-last digit of , as well as the next-to-last digit of times the last digit of . In general, for each position in the final result, we sum for all Example: To find the first digit of the answer: The units digit of plus the tens digit of plus and carry Thus, Web
This is the story of the late Jakow Trachtenberg, and how to scam people using your mathematical tricks. The Jedi Mind-Trick It's time for another little diversion. Let's look at an easy way to subtract nine. To subtract nine, just read out the number, digit by digit, but when you get the the second-last one, take one away, and add it to the one on the right. For some reason, this is much easier, even though we are doing exactly the same thing as taking 10 away and adding 1 to compensate for taking 10 away. There is a tiny complication when you get a 0 in an awkward spot: But you can read the original as “three seven six seven tenty three” and say “three seven six seven ninety four” and get the answer right. It's handy to be able to subtract 9. We say, “six”, think,”this is the second last digit, give one.” say, “four”, think,”Now it's pay-back time so take one”, say, “seven”. That is a lot of explanation, but it is important to have this little narrative in your head while you create the answer. Read this number, then turn away and recite it: How far did you get? That should be a lot easier.
