Ugh.

Congrats Alex, well-deserved!!

Congratulations Diogo 🎉 @ualberta.bsky.social you are getting a powerhouse of a researcher!

That looks delicious

Pretty wild to be living in a time when humans are being forced to work in order to even be considered deserving of life or even to be considered human at all, while simultaneously human labor is being systematically eliminated from the concept of work.

I can't believe no one in this thread has mentioned The American (2010). I am very uncritical of movies and find some enjoyment in most, but this one genuinely infuriated me.

Make Canada's voting system fair and proportional! Canadians are tired of our broken voting system. After Trudeau broke his promise of reforming our electoral system in 2015, apathy and cynicism towards our democracy has grown. If Canada is to weath...

I am personally fully supportive of Canadian electoral reform. We need to abandon first-past-the post single member ridings, and move towards a system that better represents the will of the public. This will make parties more responsive. Consider co-signing.

Wow, congrats Saurabh! All the best in your new endeavours, Dal will miss you!

A short video of said phosphorescence! #chemsky

An image frame from a single-crystal X-ray diffraction experiment on a crystal of a small organic molecule.

First #crystallography post in a while! Challenging sample, air-sens. and quickly desolvating, in the end managed to get something half decently diffracting. Wasn't expecting that the material would also be RT phosphorescent! A nice Thursday morning. Today's soundtrack: Clutch - Robot Hive/Exodus

I've just signed the global statement on AI training.

“The unlicensed use of creative works for training generative AI is a major, unjust threat to the livelihoods of the people behind those works, and must not be permitted.”

A political campaign graphic with the heading "ELECTORAL REFORM" in bold orange text. Below, the text states a commitment to replacing Ontario's first-past-the-post voting system with a mixed-member proportional system where every vote counts. It emphasizes consulting with the public, civil society, and political parties to design a made-in-Ontario system that reflects community needs. The graphic has a clean beige background with an orange stylized trillium logo in the top right corner.

📢 The Ontario NDP has once again committed to proportional representation in their platform!

They promise to replace first-past-the-post with a mixed-member proportional system where every vote counts.

Let’s make sure electoral reform stays on the agenda!

A data visualization graphic titled "Which voters back proportional representation?" shows the results of a national poll conducted by EKOS Research. A large circular chart indicates that 68% of Canadians support proportional representation, while smaller charts display support levels by party: 72% of Liberal voters, 54% of Conservative voters, 83% of NDP voters, 87% of Green voters, 74% of Bloc voters, and 77% of PPC voters. The chart uses green for support, red for opposition, and gray for "don't know." The EKOS logo appears in the bottom left, and the website www.fairvote.ca/prpoll2025 is displayed at the bottom.

🚨 BREAKING: 68% of Canadians want to make every vote count! 🚨

A new poll confirms overwhelming support for proportional representation. Will the next Liberal leader listen?

But the rest, absolutely agree. We need to come together as a country, and care about and support each other, more than ever right now. Looking forward to seeing the results of your plans.

You had me until "more roads". We don't need "more roads", the infrastructure you should be investing in is for functional, affordable, convenient and accessible public and active transit; Ottawa is already so terminally auto-centric and the time to divest from this was long ago. 1/2

The U.S. is a warning: first-past-the-post weakens democracy, fueling a two-party system, policy lurch, and instability.

A small vote edge shouldn’t mean total control.

Proportional representation ensures every vote counts and keeps democracy strong.

A political campaign promise from the Nova Scotia Liberal Party titled "Implement Proportional Representation." The text states that the province needs electoral reform to ensure politicians are accountable to the people and that the system reflects society. It pledges to amend the Elections Act to introduce a moderate proportional representation model that maintains strong regional representation. An expert commission will be appointed to determine the plan’s details and ensure protected representation for Acadians and African Nova Scotians. A cost estimate at the bottom states: "No additional spending required."

Repost if you think @bonnieforontario.bsky.social and the @ontarioliberal.bsky.social party should take a page from the Nova Scotia Liberals and put proportional representation in their platform.

PSA: Dear fellow residents of Ontario, Canada, the provincial election is Feb 27, 2025.

The ethical case for resisting AI I had my moment of reality regarding generative AI in my chemistry and physics classes this past term. I’ve always had the student frustration “I can’t Google your homework problems!” as a point of…

For the evening crowd: I put words to my nagging concerns, which last semester became fully realized fears, about how students use generative AI - despite the very real harms that generative AI has caused and continues to cause.

We have a lot to think about as we write our syllabi.
