It’s the first day of Advent and for a few years now I’ve been taking the time to fill a calendar in a recreational and fun way. Christmas spirit, are you there? Let’s go for this Advent calendar version 2025!
01. A quote that carries meâ–˛
This year, I chose another quote by Henri Poincaré. Last year, I opted for a quote about life. Today, I have decided to select one about science, where the French scientist shares a certain sense of humor, if not a definite one. 🙂
Il ne faut pas dire que la science est utile parce qu’elle nous permet de construire des machines. Il faut dire : les machines sont utiles parce qu’elles nous permettent de faire de la science.
Henri Poincaré, taken from the French work entitled La Valeur de la Science.
My personal translation
We should not say that science is useful because it allows us to build machines. We should say: machines are useful because they allow us to do science.

02. An image that makes me dreamâ–˛
I choose a starry photo of the cosmos: Cosmic Cliffs of the Carina Nebula because the starry sky always thrills me.

03. A musical crushâ–˛
This year I’m choosing the soundtrack from the animated series based on the Saint Seiya manga, Les chevaliers du zodiaque in the French version. This saga is one of the fictional universes that I appreciate, reminding me of my childhood. There are several OSTs (Original SoundTracks); I choose a “piano cover” of the excerpt entitled Sad brothers, Frères tristes in French.
