Randy Lewis, Department of Physics and Astronomy, York University
All high school physics teachers are warmly invited to York University at 5:30 p.m. on Friday November 3, 2023. Professors in our Department of Physics and Astronomy value this annual event and are looking forward to connecting with high school teachers again this year.
Three York professors will give short talks about their research. You can see our telescope (which is the largest on any university campus in Canada) observing the opposition of Jupiter. Dinner and drinks will be provided, and there will be opportunities for casual conversations with familiar friends and new colleagues. We also have a few textbooks that are no longer needed at York, and we are glad to donate these to any high school teachers who can make good use of them.
Details can be found at this website: https://www.yorku.ca/science/physics/outreach/high-school-teachers-night/
Best wishes for the school year, and we hope to see you at York!

Orbax, Production Specialist for Physics Education Content, Department of Physics, University of Guelph
Greetings everyone! Orbax here. For those of you who don’t know me, I’ve been a member of the Department of Physics at the University of Guelph as an instructor for over 13 years now, and most recently as a production specialist in physics education content. Just like you, I love physics and I love teaching physics. I remember when I was young laying in my parents’ bed and poring through a book my father had from his university class on astronomy. I had very little understanding of what I was looking at in those pictures but I knew that the fantastic images in front of me showed a universe that laid just beyond the clouds, one that captured my imagination and that sent me down a path to becoming a physicist.
Since then my career has taken me to many places but I have never lost the fascination I’ve always held for outer space. I feel there are few things more galvanizing to scientists and interesting to the population as a whole than space exploration. As such, I’ve started a video series of monthly ‘Star Gazing Guides’. Very much in the tradition of the old Jack Horkheimer: Star Gazer
series (does anyone else remember those?), we take a look around the night sky for upcoming events of interest. The videos are very much aimed at the general population with little or no astronomy experience, but as a physics teacher, I try to use a portion of the video to slyly backdoor some actual physics education content. We talk about wavelengths of light, rotational axes, basic planetary interactions, and try to explain things like the solstice or an eclipse. Read More...

There’s a lot of good physics (and math) embedded in the grade nine space unit, if you know where to look for it. David Butler is a retired computer scientist who is fascinated with space, and he’s applied his mathematical background to explaining, in simple terms, what’s behind the fancy pictures we see from NASA, and how we know what we know about the universe. To do this he’s created a series of video books focusing on different topics, as well as hundreds of short classroom-ready video clips on topics ranging from astronomy to quantum mechanics.

Black holes are big news these days. Unfortunately a significant number of statements in the press are not only mistaken but wrong in ways that obscure the truly interesting and important things we know about black holes. This article hopes to clarify a number of points about what black holes are and are not. Read More...

What is the Event Horizon Telescope?
The Event Horizon Telescope (EHT) is a network of radio telescopes spread across the globe. By pooling data from each instrument, it achieves the same effective resolution as a dish the size of the entire planet! What did it discover?
The EHT collaboration has just released the first event-horizon-scale images of M87*, a supermassive black hole at the centre of galaxy M87. The image shows an asymmetric ring of light surrounding a circular shadow. The ring of light is not the accretion disk, it is the footprint of the relativistic jet created by M87*. The asymmetry is evidence for the direction of the black hole’s spin. The size of the shadow reveals the mass of M87* which can then be used to calculate the radius of the event horizon. Note, the shadow is not the event horizon. Read More...

The announcement that LIGO has detected gravity waves may have you scrambling to answer your student’s questions. This news connects to many topics in high school physics including waves and vibrations, interference of light, changing models of science and the analysis of data - especially the problem of signal to noise ratios. Many teaching resources have been suggested (listed at the bottom) and these have been examined to select which are the most useful for high school physics teachers. The selected videos are well-scaffolded and paced. They make good use of animations, physical models and analogies and showed a wide diversity in the people interviewed. Demos and activities were selected which require minimal prep time and cost for the teacher and which provide active-learning experiences for the student. Read More...
