Here are some small things I gathered over the years and did not know where to put.

- Michael Barany - A Dusty Discipline or how the blackboard plays a crucial role in the construction mathematical knowledge (and why mathematicians complain when they have to use something else)
- Une petite histoire de la géométrie algébrique by André Weil.
- Le changement de perspective avec le langage des schémas , by Michel Raynaud.
- William Thurston - On Proof and Progress on his own experience, and what it means to make progress in mathematics.
- Hardy - The Indian mathematician Ramanujan about the way Ramanujan thought, and his conjectures (whether true or false).
- Gian-Carlo Rota - The Pernicious Influence of Mathematics upon Philosophy , or why abuse of formalism outside mathematics and logic is a slippery slope.
