Auschwitz personnel, 1944. Ordinary people, not monsters, make atrocities happen

Posted on 2020/11/22 by Carl Robitaille

Nazi horror didn’t start with genocide.

It started with words…

…with the dehumanizing of minority groups.

Once they were seen as less than human, anything could be done to them.

If you’re waiting for genocide to start before you speak up, you’re leaving it too late.

Microlesson on vortices!

Posted on 2020/11/22 by Carl Robitaille

Here's a microlesson on another topic I couldn't talk about in my book; vortices! #physics #science

Let's talk about what they are, which types of vortex are common, and how understanding them is connected to one of the biggest open problems in physics. pic.twitter.com/KMKExAVVkj

Dix choses que vous ignoriez sûrement sur les drapeaux

Pour le drapeau, le changement ce n’est pas maintenant !

2/2
Parfois à la télévision, la bande blanche du drapeau placée derrière un locuteur est beaucoup plus étroite que les bandes bleue et rouge (image 1). Cela est fait exprès pour un éventuel cadrage resserré qui sinon, ne laisserait voir quasiment que du blanc à l'écran (image 2). pic.twitter.com/wYJxKzow90

Ordinary gears don’t cut this much into their neighbour’s space. It’s also difficult to get gears with only five teeth to drive each other smoothly. https://t.co/ONCnKtiC1U
