NSERC - Gender Based Analysis Plus in NSERC Programs: Summary Report 2024

NSERC has released data on the gender distribution of some of its grants/awards. The fraction of women applying for & receiving grants/awards beyond the postdoc level is below the fraction of women holding science & engineering faculty positions (~35%). 🧪👩🏻‍🔬 #Canada

I was wondering about internal reflection. It's a fascinating conundrum.

Calcite provides so much wonderful inspiration! If a mineral can do this for so many, it certainly deserves your vote today ⚒️🧪 geology #MinCupwww.mineralcup.org/2024/vote/r2m7

This is way too close:

Here's an interesting discussion that resulted from someone seeing the same pattern and someone else trying to replicate it:

Unexpected laser pattern through calcite crystal

I've bought a calcite crystal and tried to see birefringence by shining a laser through it. I get a split spot in the centre of a sixfold pattern The hexagonal pattern resembles a diffraction patt...

I just used those exact images in a clicker question. I can’t remember where I got them from.

Looks like the same thing is happening here:

Hey #ITeachPhysics ⚛️, anyone know what's going on here?

Now, I have a small piece of calcite that I chipped out of a boulder. Very scrappy and difficult to see through it to get the double image, so thought I'd shine a laser through it, and was surprised to see a pattern like this. What's going on?
