A friend of mine had a disagreement with some colleagues at a pd session. My friend correctly asserted that when you put ice into a blender for a smoothie, the ice does not undergo a state change, except for some minor melting due to heat from friction. The ice will melt as the smoothie warms … Continue reading
I’ve heard about the challenges of indoor air quality a few times. I’ve worked in buildings that had reputations as sick buildings. And oh my word, I’ve been questioning the quality of my home air since moving to working from home. While there are factors that impact our indoor air quality that are independent of … Continue reading
I used to run a nature information line and in the spring we would have any number of people calling with concerns about “abandoned” baby animals. I didn’t mind the phone calls to be honest as it meant the person called before taking action. Generally the advice is the same, look for actual signs of … Continue reading
Typically, when I taught the characteristics of life I would mention that viruses mess with our understanding of life but wouldn’t go much further, it was outside the scope of the course. For obvious reasons — ie the current covid-19 pandemic– I’ve been thinking about the tiny little virus and its tenacity for life, wrapped … Continue reading

I joked that I interpreted the animals for the people and the people for the animals. Zoos have some negative history to … Continue reading
We are living in interesting times. With the threat of getting sick from Covid-19, which is enough to cause anxiety, we are also isolating and restricting our movements. I’ve noticed an upsurge on views on my post on exercise and mental health so I thought I would look into a related topic: music and anxiety. … Continue reading
If you’re like me, you may have had a sudden change of venue for your workday. I’ve been working at home for about two weeks now, since the coronavirus pandemic has triggered the vacating of pretty much every public space around the world. Yesterday I gave in and accepted that this was a long term … Continue reading
It is later in March and it is currently snowing. Sure, we get late snowstorms, but there’s still several feet of snow, the river is still frozen, and the daily temperatures still sit below freezing regularly. This is definitely a late spring. But the Canada geese are back from their yearly migration, searching for food … Continue reading
