Today is Earth Day, and it's important for several reasons, most notably the Paris Agreement is now open for signatures. The US better be rushing to sign. Climate scientists have been calling for action for decades now. I hope to see my country taking established science more seriously and doing more to combat climate problems. There are more than 7.3 billion people in the world, which is twice the human population in my birth year of 1970. Nobody can be blamed for wanting a car, a nice home with air conditioning, and all the other comforts of modern living. But it would help everyone to understand that we all share a common ancestor, just as we share common ancestors with all living things. We are just one of a whole multitude of species occupying Earth. Let's leave it better than we found it.
Yesterday was a fun day. I woke up to the news that Queen Elizabeth II turned 90. As someone from a country with a secular government and no monarchy, especially a country that tossed out the English more than two centuries ago, I find the English monarchy to be rather silly. But I suppose it's been neat being here when QEII became the longest serving monarch and when she turned 90. Maybe the English will give up the monarchy someday, but traditions die hard.
I got a chance to talk research yesterday. My colleague asked me to guest lecture in his Sports Engineering course. I never turn down an opportunity to talk to students about my research work. They were a fun bunch of kids who asked great questions as I talked to them about my Tour de France and World Cup football work. A physicist like me tries to tease out of the natural world what is important for a particular phenomenon. The students I talked to certainly knew that worrying about Jupiter's pull on a cyclist would be a waste of time, whereas cyclist power output is worth studying.
After a fun lecture, I enjoyed a few pints at the Red Deer with a couple of colleagues. Few things finish off a great day better than delicious cask ale and palaver with friends. My college needs a pub!
