How do we choose between economic losses and the likelihood of people dying in a pandemic? Is that even a moral question to contemplate? Like it or not, it’s something we have to think about now. The classic approach is to come up with a Value of Statistical Life figure, basically the amount that society… Read More »

Turns out that bumblebees can do a lot for us in addressing the pollination crisis, where threats to honeybee populations are making it harder and harder to pollinate certain crops. Like fruit? Well, many fruit trees won’t bear fruit unless their flowers are pollinated. You’re going to need bees! When I was a kid, I… Read More »

Wondering how long the SARS-CoV-2 virus persists in the environment? The media’s been pretty vague, but this recent article from the New England Journal of Medicine is much more helpful. It shows that the virus is detectable up to 48 hours after exposure on many surfaces, particularly plastic and steel. It’s less stable on cardboard,… Read More »

I’m still seeing a lot of confusion around mortality rate figures for Covid-19. There are three figures worth understanding. The first is the case fatality rate (CFR). It measures the proportion of cases of a disease that result in fatality. To calculate it, take the number of fatalities and divide it by the sum of… Read More »

Someone I know committed suicide just recently. I didn’t know them particularly well, but they are the third person in… Read More »

I often wonder at people who are artistic, who have sudden bursts of creativity and desire to make something beautiful or whatever. I don’t have quite that same impulse – I don’t see something aesthetic and decide I want to make something similar; instead, I see something made and desire to have mastered the techniques… Read More »

Very sad to see that Carrie Fisher has passed. Gonna talk about mental health a little. Carrie Fisher was a noted sufferer of bipolar disorder, also known as manic depression. She did a lot of work to help spread awareness of the condition; if you want to know more, there are several obituary articles talking… Read More »

Well, that was interesting. I just saw The Hobbit in 3D High Frame Rate. Ignoring the plot, design, acting and so on for a moment, I was struck by the 3D response I got. Normally, I have monoscopic vision due to my extremely far-sighted left eye, so seeing something recognizably 3D was really surprising. It… Read More »

I’m far more inspired by these photos from the Paralympics than I was by anything I saw from the Olympics. There’s something much more moving about athletes overcoming physical adversity to even participate let alone win their events. Some highlights: high jump with only one leg table tennis with irregularly formed hands archery with feet… Read More »
