        A seventeenth-century theory of burning proposed that anything that burns must contain material that the theorists called"phlogiston."Burning was explained as the release of phlogiston from the combustible material to the air.Air was thought essential,since it had to provide a home for the released phlogiston.There would be a limit to the phlogiston transfer,since a given volume of air could absorb only so much phlogiston.When the air had become saturated,no additional amounts of phlogiston could leave the combustible substance,and the burning would stop.Burning would also stop when the combustance was emptied of all its phlogiston.

        Although the phlogiston theory was self-consistent,it was awkward because it required that imaginative,even mysterious,properties be ascribed to phlogiston.Phlogiston was elusive.No one had ever isolated it and experimentally determined its properties.At times it seemed to show a negative weight:the residue left after burning weighted more than the material before  burning.This was true,for example,when magnesium burned.Sometimes phlogiston  seemed to show a positive weight,when,for example,wood burned,the ash weighed less than the starting material.And since so little residue was left when alcohol,kerosene,or high-grade coapl burned,these obviously different materials were thought to be  pure or nearly pure phlogiston.

        In the eighteenth century,Antoine Lavoisier,on the basis of careful experimentation,was led to propose a different theory of burning ,one that required a constituent or air-later shown to be oxygen-for ,combustion.Since the weight of the oxygen isalways added,the weight of the products of combustion including  the evolved gases,would always be greater than the weight of the starting material.

        Lavoisier's interpretation was more reasonable and straightforward than that of the phlogiston theorists.The phlogiston theory,always clumsy,because suspect,eventually fell into scientific disrepute,and was replaced by new ideas.

             Just two months after the flight of Apollo 10,the Apollo 11 astronouts made their historic landing on the surface of the moon.This momentous trip for humanity also provided scientists with an abundance of material for study;from rock and soil samples brought back from the Moon,scientists have been able to determine much about the composition of the Moon as well as to draw inferences about the development of the Moon from its composition.               The Moon soil that came back on Apollo 11 contains small bits of rock and glass which were probably ground from larger rocks when meteors impacted with the surface of the Moon.The bits of glass are spherical in shape and constitute approximately half of the Moon soil.Scientists found no trace of animal or plant life in this soil.               In addition to the Moon soil,astronauts gathered two basic types of rocks from the surface of the Moon:basalt and breccia.Basalt is a cooled and hardened volcanic lava common to the E

             During the heyday of the railroads,when Ameria's rail system provided the bulk of the country's passenger and freight transportation,various types of railroad cars were in servive to accomplish the varied tasks handled by the railroads.One type of car that was not available for public use prior to the civil War,however,was a sleeping car,ideas for sleeping cars abounded at the time, but these ideas were unworkable.It unfortunately took the death of a president to make the sleeping car a viable reality.               Cabinet-maker George M.Pullman had recognized the demand for sleeping cars and had worked on developing experimental models of sleeping cars in the decade leading up to the Civil War.However,in spite of the fact that he had made successful test runs on the chicago and Alton Railroads with his models,he was unable to sell his idea because his models were too wide and too high for existing train stations and bridges.In 1863,after spending time working as

         Today ,the most universally known style of both men and women is jeans;these trousers are worn throuhout the world on a variety of occasions and in diverse situations.Also called levis or denims,jeans have an interesting history,one that is intermixed with the derivation of the words jeans,denims,and levis.               The word jeans is derived from the name of the place where a similar style of plants developed.In the sixteenth century,sailors from Genoa,Italy,wore a rather unique type of cotton trousers.In the French language,the word for the city of Genoa and for the people from that city is Genes;this name became attached to the specific style of pants worn by the sailors from this city and developed into the word jeans that today describes the descendents of the Genovese sailors' cotton pants.               Similar to the word jeans,the word denim is also derived from a place name.In the seventeenth century,French tailors began making trousers out of a specialized t
