=============================================================================== Title: Of Summer and Writing Date: 19-08-2022 =============================================================================== Recently I spent a beautiful week in Camargue (France). It is a region located in the south of the country, where the impact of the gypsy culture is ubiquitous. It is a land of bulls, horses and pink flamingos. I took this chance to take many pictures with my reflex camera - the results are not great but some of them turned out really nice. July has been completely dedicated to exams. My plans were to write my thesis during August in order to start September with a 60/70% of the total work done. Unfortunately I'm late: my writing speed is rather slow and a few days ago I got sick. It's not covid, it must be some other flu virus - it's really making me feel broken: fever, cough, sore throat and headache. Right now, my pdf viewer shows a total of 31 pages. Since I had planned to write about 100 pages, I'm at 31% of the work. With just 10 days to double it. Impossible. It seems that September will be a tough month. In this first part of the thesis I've discussed part of the theoretical framework upon which I did my research. On the one hand we have the quantum mechanics treatment of vibrations, on the other there is Group Theory. Although interesting, I'm not going to talk about QM here. But I'd like you - my fellow readers - to search on your favorite search engine for "Galois". This guy was the mathematical genius behind a fundamental theory which is part of the Abstract Algebra. Group theory has deep implications on our understanding of nature and, in chemistry, plays a crucial role in the description and exploitation of symmetries. Galois died at the age of 20, after the injuries reported during a duel of honor. The night before the duel, he stayed awake in order to collect all his mathematical work that was, at that time, unpublished. He knew that the next day his life would come to the end.
