Here's a Sudbury.com article on the 2026 Intercollegiate Mine Emergency Rescue Competition (IMERC) that our Laurentian mine rescue team hosted last week with the help of Ontario Mine Rescue. Thanks to all the students who helped organize and volunteer! www.sudbury.com/local-news/s...

Students rappel into the depths during mine rescue competition

Nine teams from eight post-secondary institutions from throughout Canada and the United States participated in this week’s Laurentian University-hosted competition, for which the home team ended up pr...

One of our colleagues, Tracy Fleury, is the third on Team Homan and is currently at the Winter Olympics competing in women's curling. They have the 🇨🇦-🇰🇷 game streaming on the screens on campus.

Spotify's shuffle gave me what seemed like an ominous message on my commute home: "Bring me to life! (Your ex-lover is dead, for what it's worth.)" So now I am trying to think of better messages that could come from three song titles…

Thanks to the Laurentian University Engineering Student Society (#LUESS) for organizing yesterday's successful Purple Day events! We trust all the first-year engineering students enjoyed themselves. Hopefully, everyone's skin & hair will be (almost?) back to its normal hue by Monday.

We uncovered an envelope of old drawings in the engineering office this morning, all related to old mining practices. My favourite is this one on how to lower a mule down a mine shaft. No record of the mules' response is given. (We believe the English was translated from the French text.)

This drawing has six illustrations with captions underneath. There is also a block of text explaining the preparation of the animal. All text is in English and French, but only the English text is as follows:

My sweetheart's a mule in the mine

1. Preparing the mule for lowering into the mine required heavy webbed harness with rope attachments.
2. Placing the ropes under the hind legs forced the animal into a sitting position.
3. The hind legs were pulled into position and tied.
4. The front legs were then secured.
5. From a hook under the cage, the mule was attached and swung into the shaft for lowering.
6. The holding hook was built so as to place the mule diagonal in the shaft compartment. This was necessary due to the small compartment size.

Lowering and hoisting was done by a three man crew. Prior to moving, the animal was "gounted" for three days. The animal went without food or water for this period. If not done, the was the danger of a ruptured bladder or suffocation.

Not a meteorologist, but I feel Iike the folks at Environment Canada are being non-committal with that icon: 🌞 + 🌧 + ⛅️ + 🌩? (At least it doesn't include ❄️ + 🦈 + 🌪.)

Screen shot of some of the Environment Canada forecast for today in Sudbury, Ontario. At 6pm there is a high of 19°C and 70% probability of precipitation. Weather conditions described as "Chance of showers. Risk of thunderstorms." The icon for the weather is combination of the sun, rain and rain clouds, plus dark thundercloud and lightnight.

Happy Mother's Day! A special shut-out to all those who have to work today so that others can celebrate. My SIL is a chef at a fancy hotel. They are expecting 700-800 for brunch across two dining rooms! Be sure to tip your servers well today!

My final marks are all submitted, so my winter-term course work is officially done! 🎉🥳🎈 Enjoy these renderings of some of the group projects completed by my 1st-year #ENGR1017 computer aided design (CAD) class, where they had to recreate digital models of a commercial product. Colour me impressed.
