Deafheaven played in Paris again tonight, in the belly of a boat on the Seine. Absolutely phenomenal live band!

The queen of pop, Robyn, was in Paris today and she was very good, and cool, and sweet, and glorious ♥️

I can't get over how cool this painting on a wall in my Parisian neighborhood is.

<- happy member of #Squarepusher massive, listening to his new album. Track 5 Kromec's bassline is a pinnacle of the finest acid artistry.

Deafheaven in Paris - it was short (because supporting band tonight) but tight sounding and awesome 🤘

Together with my friends and colleagues of LIDYL at CEA Saclay, I wrote a little history of the discoveries of this year's Nobel Prize in Physics for attosecond pulses. It's out now in the journal Photoniques: doi.org/10.1051/phot...

Our friends of Institut Polytechnique de Paris (IP-Paris) have talked to me and my colleagues of Laboratoire d'Optique Appliquée (LOA) about attosecond physics, subject of this year's Nobel Prize, and the past and current contributions to this field: www.ip-paris.fr/en/news/atto...

From left to right: myself, and graduate students Antoine, Jaismeen, and Christian in our laboratory, behind the vacuum chamber in which we do our attosecond laser-plasma physics experiments.
