Net Zero

I’m a bit frustrated when I see a lot of countries advertising their aim for net zero emissions by 2050. While the goal is laudable, communication around it is rather misleading. Net zero emissions means that the amount of carbon you emit into the atmosphere is the same as the amount which can be absorbedContinue reading “Net Zero”

How big is a billion?

In physics we are often faced with unbelievably large numbers. In fact, studying systems with a huge number of objects is a sub-genre in itself called statistical physics. Notably, some numbers become so large that we can’t really tell them apart [1]. There is a point when addition just doesn’t make any difference to aContinue reading “How big is a billion?”

Supraconductivité

Avec un ami et collègue, Antoine Essig, nous avons récemment enregistré une vidéo pour la Fête de la Science 2020 qui explique un des phénomènes les plus spectaculaires de la physique: la supraconductivité. Si vous voulez voir des aimants qui lévitent (oui oui, vraiment!) et des matériaux qui conduisent de l’électricité sans pertes, jetez unContinue reading “Supraconductivité”

Diversité = Sagesse & résilience

J’aimerai parler de diversité et de ses bienfaits dans des domaines très différents. Lors d’une visite au musée des sciences et techniques à la Villette à Paris dernièrement, j’ai (re)découvert certains principes du bio-mimétisme [1]. L’exposition montrait certaines des astuces que le vivant a développé pour faire face aux contraintes extrêmement diverses de son environnement.Continue reading “Diversité = Sagesse & résilience”

Size is important

What do cars, electric scooters and smartphones all have in common? Among other things, they are all getting bigger. Average phone screen diagonals have tripled since the arrival of the iPhone in 2007. Lime’s newest scooter generation is 30% heavier than the last (Source: flava.co.nz). Although the average french car hasn’t gotten much longer sinceContinue reading “Size is important”

PhDs and Hammers

Imagine the problems you face as a PhD student as a bunch of nails you need to hammer into something. The nails come in all sorts of different sizes so it’s a good job you’ve brought your toolbox along with you. It contains three items: one small hammer, one medium and one large. Now atContinue reading “PhDs and Hammers”
