HYDROGEN
HYDROGEN Hydrogen, symbol H, is reactive, colorless, odorless, and tasteless gaseous element. The atomic number of hydrogen is 1. The element is usually classed in group 1 of the periodic table. Hydrogen was confused with other gases until the a British chemist demonstrated in 1766 that it was evolved by the action of sulfuric acid on metals and also showed at a later date that it was an independent substance that combined with oxygen to form water. The British chemist Joseph Priestley named th...

The term anesthetic literally means without feeling. There are many different types of anesthesia, but they are usually put into three groups. These groups are gene- r...

Marshall Field Whole Sale Store
Marshall Field Whole Sale Store The Chicago School marks the beginning of a new development in architecture. Based on the earlier Victorian models, from about 1885 great commercial structures are built with new designs and new construction techniques. During these later years Richardson produced the buildings upon which his reputation principally rests. He designed houses, community libraries, suburban railroad stations, educational buildings, and commercial and civic structures. Instead of the ...

Integral Calculus
Integral Calculus Ever wonder how scientists figure out how long it takes for the radiation from a nuclear weapon to decay? This dilemma can be solved by calculus, which helps determine the rate of decay of the radioactive material. Calculus can aid people in many everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rat...

Oxygen
Oxygen Oxygen is one of the 92 known elements. An element is a substance that cannot be decomposed into a simpler substance by any simple means. Each of the 92 naturally occurring elements are therefore one of the fundamental materials from which everything in the Universe is made. The History of Oxygen On August 1,1774, Joseph Priestley examined the effect of intense heat on mercuric oxide. He noted that an air or gas was readily expelled from the specimen. To his surprise a candle burned in th...
