Very sad to read this. She came to SMU once to do a CBC video piece where we did some physics experiments. It was a great day and though she was slightly unprepared for what we had planned, she rallied incredibly and was game to make it all work.
I interviewed Colleen a couple of times over the years. She was so gracious and so accomplished.

Just a heads-up if you're looking for a telescope for the holidays... Costco has telescopes again, and they're decent 'scopes. I got one for myself a couple yrs ago that I use at home. 🔭 (It is the time of the year where I'm getting emails wondering how/what/where to get a telescope for Xmas)

So many of his films (especially the ones he made with Masaki Kobayashi) can be summed up with this scene from "Hara-Kiri". One of the greats. His work in "The Human Condition" (all ~10hrs of it!) is some of the best film acting ever.

Did you know the colour of an LED is dependent on the band gap of the doped semiconductor inside?
And that that band gap is temperature dependent?
And!
If you (gently) dunk said LED in liqN2, neat things happen!

Outtake. Trying and failing to get a magnet to spin on a superconductor without knocking it off the disc. Three misses is a strikeout!

Let's all just take a second to appreciate this oscillating drop of liquid nitrogen. Ok? Is that too much to ask?

I'll be at the AST conference in Halifax tomorrow sharing free resources for teachers from Star Finder - the David Lane Astronomy Outreach Program. I'm finishing up my presentation now and tearing up over slides about Dave. He was really great. I miss him. He'd be thrilled about that we've created.
Nova Scotia teachers! The Star Finder team will be at the Association of Science Teachers conference on Oct 24! We'll have a table & we'll do a presentation to share resources with you. We hope we'll see you there! We'll have some printed materials (and maybe even some pens!) to hand out! 👀 ✨

I was once in a gallery in the Louvre when the security system kicked in and shut off the whole room. Automatic doors and alarms. There was another time when we watched someone walk painting to painting setting off the alarm on each. Were they an employee?

If you miss the video analysis that was available in Logger Pro that is not included in Graphical Analysis, try Sigmund (noragulfa.com/sigmund). This is a FREE, web-based app that will run on Chromebooks. #iteachphysics

Learning a 3d modelling package for another project and got carried away.

There is a frankly disturbing close-up pic of my hand on instagram right now and I don't care for it.

If I only listen to music by The Residents while editing a single lab experiment in a manual for next term, will students be able to spot which one?

Super slo-mo (1000fps) and super zoomed-in clip of a water ripples. The low resolution and weird CCD-induced color scheme leave something reminiscent of fireworks!

There's a small team of us at SMU creating free astronomy content and lesson plans for science teachers. (Specifically Grade 9 Science Teachers in NS to start, but it's also pretty adaptable for broader audiences). It's all online already, follow along. ✨ @smuhalifax.bsky.social
