Today my Facebook feed featured memes that mocked Trump for telling people to drink bleach, pour it into their bodily orifices, etc. He did say some reckless things, but Donald Trump did *not* suggest that people inject bleach, drink disinfectant, or expose their bodily orifices to sunlight. An opinion on the president is more valuable if…
I’m very conscious that my lockdown experience has been fairly smooth. I’m teaching two classes right now, versions of which I have already taught online. At home, my nuclear family is getting restless and bored, but we’re busy and productive. Yesterday afternoon I went for a walk with my son in our quiet little suburb.…
The number of weekly COVID-19 deaths in America has recently surpassed the 2018 average weekly death rates for heart disease (now the second most common cause of death) and cancer (now in third place). As a kid in school, I expected scientists to be able to provide the one and only correct answer, because that’s…
This is just an excerpt. Read the whole thing.
A few interesting bits I found interesting to explore: There are two different ways to view the exact same data: The logarithmic scale shows a great comparison of the magnitude of growth between countries, but less of the human impact. The linear scale shows the real human impact — a growth twice the size is twice the number of…
Copper is antimicrobial. It kills bacteria and viruses, sometimes within minutes. In the 19th century, exposure to copper would have been an early version of constantly sanitizing one’s hands. Since then, studies have shown that copper is able to destroy the microbes that most threaten our lives. It has been shown to kill a long list…
Those mean fake news people at the Washington Post are at it again, this time pushing a series of four simulations that vividly illustrate the impact of social distancing. Where do they get off, creating clear and informative graphics to illustrate a scientific principle? What do they think they’re doing, some kind of public service?…
People typically think of soap as gentle and soothing, but from the perspective of microorganisms, it is often extremely destructive. A drop of ordinary soap diluted in water is sufficient to rupture and kill many types of bacteria and viruses, including the new coronavirus that is currently circling the globe. The secret to soap’s impressive…
Space Shuttle Challenger Destroyed (my reflection on the 28th anniversary in 2014) I was in my final semester of high school. I remember Principal Burch came over the loudspeaker to announce that the Challenger “blew up on the pad,” which I knew wasn’t true because I was watching a TV… probably in the library. Years…
The plain fact is that the planet does not need more successful people. But it does desperately need more peacemakers, healers, restorers, storytellers, and lovers of every kind. It needs people who live well in their places. It needs people of moral courage wiling to join the fight to make the world habitable and humane.…
Turns out, getting a STEM education may help you get a good job early but if you want a good career, you’re better off in liberal arts lane. In other words, even if you’re only measuring money, a liberal arts education is probably worth a ton more than most people may think. […] [B]y the time…
Fascinating article about how the extreme stress of chess tournaments affects the bodies of grandmasters. At 5-foot-6, Caruana has a lean frame, his legs angular and toned. He also has a packed schedule for the day: a 5-mile run, an hour of tennis, half an hour of basketball and at least an hour of swimming.…
Rewatching Star Trek: The Next Generation after a 20-year break. The Enterprise spends a lot of time in a budget-saving black void, where the crew scans things, searches databases, launches a probe, navigates in circles, gives up, sets a self-destruct timer, philosophizes about death, shuts off the timer, and warps away. I had never seen…
There’s so much I don’t know! When teaching rhetoric, I often use “Is light a wave, or is it a particle?” as an example of a false dichotomy. My high school physics teacher (Rear Admiral Edward Metcalfe Peebles) set up a lecture giving us the “pro-wave” evidence and the “pro-particle” evidence and inviting us to…
I try to watch this every July to commemorate the Apollo 11 mission to the moon. Based on a true story, The Dish focuses on the staff of the Australian radio antenna charged with relaying the TV signals from the Apollo 11 moonwalk. The story was exaggerated here and there for dramatic effect, but does…
50 years ago today, three humans were on their way to the moon for the first time. Todd Douglas Miller’s documentary “Apollo 11” uses lots of found footage (including longer cuts of iconic sequences I know well, and plenty I’ve never seen before) arranged on split-screen multi-angle shots, woven together with low-key graphics and the…
Beyond making the audience cringe and, hopefully, bring a father a little closer to his son or daughter in a healthy manner, puns have given researchers insight into how the left side of the brain engages with the right side. Researchers showed that the brain’s left hemisphere processes the language of the pun first, while…
Tired brain can’t quite process this Wired summary of a scholarly paper, but I enjoyed how the good writing helped me peek into a field I know so little about. Time moves as it does because humans are biologically, neurologically, philosophically hardwired to experience it that way. It’s like a macro-scale version of Schrödinger’s cat.…
