36 years ago today, 14 women, most of whom were studying engineering, were killed by an anti-feminist gun man at École Polytechnique in Montreal. I was a young graduate student studying physics at the time and I will never forget. #MontrealMassacre #NeverForget 🧪 👩‍🔬 ⚛️ 🎢 #AcademicSky 🇨🇦

A reminder that this gif and a similar one for the transit method are on Wikimedia Commons for anyone to use.

I'm actually putting together a teaching dossier at the moment and I'd love to hear from people if you've used any of my gifs for teaching, outreach, or science stuff!

Omgomg my gif demonstrating using the doppler/radial velocity method for detecting exoplanets was used in the latest PBS Space Time!!!!! 🤩

Twitter now displays where accounts are from and it has confirmed that too many of the political accounts are out of country bots.

Why are folks still there? To argue with bots? A waste of precious time while enriching the richest man on Earth.

“It is up to each of us to make the case, in language that resonates beyond academia, that science is not a luxury but a necessity,” says American Physical Society president John Doyle. “Now, as we face new challenges, advocacy must become a part of what we all do.”

What does it mean to be a physicist right now?
The scientific enterprise is under attack. Being a physicist means speaking out for it.
