TAILIEUCHUNG - General Investigations of Curved Surfaces of 1827 and 1825, by Karl Friedrich Gauss

The concept of a "chemical substance" became firmly established in the late eighteenth century after work by the chemist Joseph Proust on the composition of some pure chemical compounds such as basic copper carbonate.[6] He deduced that, "All samples of a compound have the same composition; that is, all samples have the same proportions, by mass, of the elements present in the compound." This is now known as the law of constant composition.[7] Later with the advancement of methods for chemical synthesis particularly in the realm of organic chemistry; the discovery of many more chemical elements and new techniques in. | The Project Gutenberg EBook of General Investigations of Curved Surfaces of 1827 and 1825 by Karl Friedrich Gauss This eBook is for the use of anyone anywhere at no cost and with almost no restrictions whatsoever.
