It has been a joy to spend time thinking about the challenge of detecting # darkmatter in such a vibrant, beautiful, and multicultural city as # Montreal . I have only been here once before, in about 2008, but I get much more time on this trip to walk the neighborhoods and enjoy the space and the people. And the dusting off of my French has gone … acceptably. I even learned how to ask if a shop can serve decaffeinated coffee, which I never though to ask for in France/Switzerland. Indeed, they did!
