The Road to Stellafane – Part 1 Last year, I had the great honour of being the keynote speaker at the 2025 Stellafane Convention of the Springfield Telescope Makers Association. I had such a good time at the convention, which is held over 2 days in the hills of Vermont, that I vowed this would […]

On our way to the #Stellafane annual telescope builders convention in Vermont. It is a beautiful day to start out on a road trip through Ontario!

Had a really nice weekend enjoying rain and thunder mixed with cool breezes and blue skies. Got lots of exercise, enjoyed the scenery in #Sudbury, and did a bunch of reading (still working through Ed Yong’s “An Immense World”).

It’s a stormy summer evening in #Sudbury.

Two great tastes that taste great together: Don Norman's "The Design of Everyday Things" and Cory Doctorow's "Enshittification: Why Everything Suddenly Got Worse and What To Do About It". These #books called to me over the last 24 hours. Here we go. #bookstodon

I was very sad to learn today of the passing of T. Denny Sanford, who “… provided significant gifts to the Sanford Underground Research Facility (SURF) and Crazy Horse Memorial in the Black Hills of South Dakota.” Sanford Underground Research Facility (SURF) bears his name. T. Denny SANFORD […]

The wildfire smoke mostly cleared from #Sudbury skies this weekend and resulted in a lovely, cool pair of days. After crashing yesterday (we had a GREAT time with family last week … but we were just plain tired come Saturday!) we were active today with running and bike riding. The afternoon was […]

Oh, and did I mention the miniature trains they have also on display. It was a delight to be somewhere on the fun side of the spectrum today as we marveled at the details and hunted for easter eggs in the vast displays, like the girl selling lemonade!

Today’s family outing was to the #railroad #museum in Capreol. We had an insane amount of fun crawling all over the #caboose, railroad cars, and engine they had on display. I was especially mesmerized by the mobile school, which could be pulled […] [Original post on mastodon.cooleysekula.net]

Moar fun at #ScienceNorth yesterday: a #LEGO station where you are encouraged to build a moon base. I built a moon glamping tent. My goddaughter built a moon chicken, which then promptly attacked my tent. I love my extended family.

Another fun thing from #ScienceNorth yesterday: all the hands-on exhibits!

Morning, #Sudbury. My, how the winds have shifted.
