I propose you a very small overview of Galois connections. But first, I need to answer the question : why in English ? I have realized that more and more people coming to this site are foreigners not reading French. So, I decided to write some texts in English assuming that people who can understand complex scientific texts can also read English. The other scientific texts (for grand public) and the ones about philosophy of freedom will still be written in French.

I like this overview of the mathematical structures used in theoretical physics. Click on the picture to see the full size version.
