On Racist Violence in the US

By | May 29, 2020

Cross-posting from my Facebook wall, for posterity. This morning, I wrote the following: I don’t want to comment on current affairs and specific events because I don’t know enough and my analytical nature isn’t welcome when emotions are raw. I’ll just say this: I stand in solidarity with the fight for justice and with anyone… Read More »

How to balance saving lives with the economy

By | April 20, 2020

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 »

Bumblebees are great

By | March 20, 2020

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 »

Ref – SARS-CoV-2 survival on surfaces and in aerosol

By | March 19, 2020

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 »

Case Fatality vs Mortality Rates in Covid-19

By | March 13, 2020

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 »

2020 – New Years Goals

By | January 27, 2020

I don’t usually do New Years resolutions. I’ve dabbled with them in the past, but they’ve always been vague ideals that I didn’t write down, didn’t track, and had no help of understanding my progress towards, let alone achieving. This year, I’m going to try applying SMART criteria to the process. For the uninitiated, this… Read More »

On Suicide (and shootings)

By | March 15, 2019

I was already in a grim frame of mind this evening when I heard about the shootings in Christchurch. I’m not ready to talk about them, but I wanted to write about the other thing. Someone I know committed suicide just recently. I didn’t know them particularly well, but they are the third person in… Read More »

Musings on creativity, passion, and conviction

By | June 18, 2017

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 »

3D High Frame Rate film

By | January 9, 2013

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 »
