Sorry, muss sein:
Terrawattstunden (TWh) richtig?

(Watt ist eine Leistung, also Energie pro Zeit (Joule pro Sekunde, um präzise zu sein). Man muss das mit einer Zeitdauer multiplizieren um wieder eine Energiemenge zu erhalten. Dafür wird gern eine Stunde hergenommen.

Salle Pleyel tonight 😀

I don't throw pennies because as a middle-aged romantic who's perfectly happy with his own squeezebox server, I refuse to get a streaming subscription.
Is there a service that doesn't totally screw artists over?

But I bought the record in an actual store. Streaming makes the band more money? I like to believe that those 36€ I paid for the physical record contain a sum reaching the band that corresponds to thousands of streams - feels like more than a lifetime. But maybe I'm wrong?

Why do vinyl records no longer come with download codes?
This sucks.
I'm paying big bucks for that music so why can't I have it in a digital format like I used to?

J'y serai ! Qui d'autre ?

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

See you in August in Delft for the EOSAM meeting!

You indeed should, it's an astonishing film. Not in a "big impressive" way, but a delicate and poetic one. And it touches kids and adults alike.

Lundi dans Scope on reçoit la prix Nobel Anne L’Huillier et Théo de balade mentale. Ils nous parleront des secrets de la matière et de l’infiniment rapide… ⚛️

Continuous relativistic high-harmonic generation from a kHz liquid-sheet plasma mirror We report on continuous high-harmonic generation (HHG) at 1 kHz repetition rate from a liquid-sheet plasma mirror driven by relativistic-intensity near-single-cycle light transients. Through precise c...

Our recent paper in @opticapubsgroup.bsky.social Optics Letters presents the first relativistic plasma-mirror high harmonic generation on a liquid-sheet target.

This is a real game changer for plasma mirrors !
