Potpourri

This appendix contains a potpourri of miscellaneous information that may be needed occasionally. 

The story of luminescence advances since 1970 is best found in the current literature. It is too large and diversified to be readily summarized in a single article and too recent to edit for the most important events. Luminescence studies are so pervasive throughout all the fields of science that each special sphere of inquiry could have its own recent history of luminescence. Many of the most important developments of today will necessarily remain hidden to most scientists until later discoveries reveal their significance. For these reasons, this report continues with a personal selection of topics, chosen to guide the reader to a potpourri of interesting recent reports. 

Buckland, Raymond. Ray Buckland s magic cauldron a potpourri of matters metaphysical. St Paul , 1995. 188p. 

Irrelevant of one s personal opinion, Freeman Dyson s toy model has enriched and enlarged the potpourri of (sometimes) bold theories by one further bouncy, glitzy hypothesis.

After that I started reacting to potpourri and all kinds of fragrances. I absolutely could not go into shops with scents. Later the headaches got worse and I began to notice a little tremor in my brain. I still hadn t yet reached the point where I would lose my thoughts completely. I was able to continue teaching but I had to cut back to part-time, because my body was letting me know that it needed rest. 

This chapter, therefore, ends the monograph with a potpourri of reactions all of which occur without a change in oxidation state. In many cases, the reaction is one of nucleophilic attack at an electrophilic C-atom. The result is often hydrolytic bond cleavage (e.g., in carbohydrate conjugates, disubstitut-ed methylene and methine groups, imines, oximes, isocyanates, and nitriles, and various ring systems) or a nucleophilic substitution (e.g., hydrolytic de-halogenation of halocarbons and chloroplatin derivatives, and cyclization reactions). The formation of multiple bonds by dehydration is a special case to be discussed separately. 

For those of you with a fondness for numbers, I close this section with a potpourri of fascinating facts.
