Writing invention

For large departures from T, we have to fall back on eqn. (5.21) in order to work out Wf. Thermodynamics people soon got fed up with writing H - TS all the time and invented a new term, the Gibbs function G, defined by... 

After completing a doctorate, he headed to Germany for a postdoctoral fellowship, then returned to Russia where he set about writing a book aimed at summarizing all of inorganic chemistry. It was while writing this book that he was forced to invent the organizing principle with which he is now invariably connected, namely the periodic system of the elements. 

For a thorough understanding of stereochemistry, it is useful to examine molecular models (like those depicted in Fig. 4.1). However, this is not feasible when writing on paper or a blackboard. In 1891, Emil Fischer greatly served the interests of chemistry by inventing the Fischer projection, a method of representing tetrahedral carbon atoms on paper. By this convention, the model is held so that the two bonds in front of the paper are horizontal and those behind the paper are vertical.

Barton, D. H. R. Beaton, J. M. Geller, L. E. Pechet, M. M. J. Am. Chem. Soc. 1960, 82, 2640. In 1960, Derek Barton took a vacation in Cambridge, Massachusetts he worked in a small research institute called the Research Institute for Medicine and Chemistry. In order to make the adrenocortical hormone aldosterol. Barton invented the Barton nitrite photolysis by simply writing down on a piece of paper what he thought would be an ideal process. His skilled collaborator. Dr. John Beaton, was able to reduce it to practice. They were able to make 40 to 50 g of aldosterol at a time when the total world supply was only about 10 mg. Barton considered it his most satisfying piece of work.
