Of course, if this first form of physical relativity is qualified “Galilean,” it is because Galileo had something to do in its formulation. The introduction of this principle is one of the main elements of the epistemological revolution to which I referred earlier. This article is therefore a continuation of the series on the history of science that I started. It will also be the occasion, once again, to introduce some concepts that will be useful for future popularisation articles to come.
I have already mentioned it: it is about time that I present the topics that I am interested in my work. As I have indicated on this site home page and as can be deduced from my resume, my areas of expertise are applied mathematics and theoretical computer science. My scope is physical oceanography. Specifically, I am reproducing ocean dynamics on computers.
However, though being a still evolving discipline, the study of ocean dynamics has a long history. The oldest references I have found were written during the antique times. The main topic on ocean dynamics they address is tide. I intend to present this story here. Much of the information you will find in the following comes from Bernard Simon’s La Marée océanique côtière1B. Simon, 2007. La Marée océanique côtière, collection “Synthèses”, Institut océanographique éditeur.. The following is an extract from the introduction of my Ph.D. thesis2Y. Le Bars, 2010. Modélisation de la dynamique océanique barotrope dans l’estuaire et le plateau amazoniens, Ph.D. thesis, Université de Toulouse III – Paul Sabatier.. This thesis focused on the development of an ocean model and its application to the estuary of the Amazon, so I do not claim to have achieved a definitive historical study: the following is a summary, albeit detailed, but with all the limitations of this exercise.
Is it because it concerns the origins of things? Anyway, the Big Bang is a scientific subject which everyone seems to have heard of. However, it appears that general ideas about it are not really clear.
As it will be question of the Big Bang in the subjects I will address soon in this website, here is an opportunity to inaugurate scientific popularisation articles in my blog: I propose to present the basics of the Big Bang, using simple experiments that everyone can do at home.
