Opinion: U of W delivers lesson for downtown development
A few weeks back, I moderated a lively discussion on the future of Winnipeg’s downtown. It was a conversation that has been held many times before and certainly won’t be the last.

Bob Ricklefs RIP. One of the giants of ecology. His textbooks were the gateway to the field for many students. His papers were invariably thoughtful, well-argued and provocative, even those I disagreed with. 🌏🧪🌐

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."
