Some leading figures, including Étienne Ghys and Aurélien Alvarez, have contributed to its success, though it would be difficult to name them all. For technical and editorial reasons, the website was revamped a few weeks ago, with particular attention paid to its appearance and readability. It continues to feature outstanding articles, written mainly by researchers who make recent advances in mathematics and the history of the discipline accessible to everyone. The articles are still graded from green (for readers who may have forgotten everything they learned about mathematics at school) to black (for a more knowledgeable audience), but are now all available as PDFs. As before, the website’s blog section features opinion pieces, interviews, challenges, puzzles, news, beautiful images, a press roundup, etc. In short, the new look of this treasure-filled website offers a great opportunity to spend hours browsing without noticing the time go by!
