tailieunhanh - Researches on curves of the second order, by George Whitehead Hearn

Chemists frequently refer to chemical compounds using chemical formulae or molecular structure of the compound. There has been a phenomenal growth in the number of chemical compounds being synthesized (or isolated), and then reported in the scientific literature by professional chemists around the world.[13] An enormous number of chemical compounds are possible through the chemical combination of the known chemical elements. As of May 2011, about sixty million chemical compounds are known.[14] The names of many of these compounds are often nontrivial and hence not very easy to remember or cite accurately. Also it is difficult to keep the track. | Project Gutenberg s Researches on curves of the second order by George Whitehead Hearn This eBook is for the use of anyone anywhere at no cost and with almost no restrictions whatsoever.
