John started out his career as a physicist (particle physics, for five years — remember bubble chambers?), thinking he would make a better living that way than with his other main interest, music. But doing physics is not nearly as exciting as reading about it. And then there was the job situation at the time (early 1970s). So after five years, he switched to l’informatique (IT, system programmer, etc.) with the French Centre National de Recherche Scientifique. Since retirement in 2005, he has spent most of his time reading, traveling, eating and drinking well, and being with his cats (two now) and dog and Siv.
John has often observed that when men (and perhaps women too) get older — reaching what is sometimes called the third age — their interests often change. Some become interested in world religions, one he has heard of went throught the writings of the great philosophers, some may decide to read all of Shakespeare or some other Great Author, some become engaged in a particular field or form of politics, and so on. Some of these are really great ideas and some are quite silly and that does not really matter, does it?.
John has become fascinated by things he has been reading about science, especially physics and cosmology, neuroscience and evolutionary biology. He would like to have some at-least approximate notion of current ideas of the relation between the “real” world of physics (and geology and …) and our internal mental model of it (including of ourselves). Whatever winds up on this site is the result of his attempts to structure or order his reading and his thoughts on these subjects.
He is also astonished at the lack of scientific knowledge of much of the general public. So he would also like to do a survey of how science sees things.
Like lots of people, he is occasionally seized by the need to assemble his thoughts by writing them down. Or, he may just feel like discussing something that no one available is much interested in. John does not really expect anyone else to read this. Well, maybe Siv. Sometimes. Hopefully, he will have fun anyway.
Which does not really matter in the long run… because you all know what Keynes said about that.1If not, then do a search it.
