Tunnel Optical Illusion Shared On Reddit Is Blowing People’s Minds
June 5, 2022Bloomberg Billionaires Index
June 4, 2022Found it strange that the
@Bloomberg
Billionaires’ Index (https://bloomberg.com/billionaires) does not include @MikeBloomberg
(who according to Wikipedia is the 16th richest person in the world). Maybe this prevents conflicts in reporting but it’s also (obviously) inaccurate.
A common sunscreen ingredient turns toxic in the sea — anemones suggest why
June 4, 2022One wonders if this can happen with oxybenzone sunscreen on people too. Perhaps a good reason to favor TiO2 or ZnO sunscreens.
The Renewable-Energy Revolution Will Need Renewable Storage | The New Yorker
June 4, 2022QT:{{”
“I’m kind of surprised and encouraged that the solutions to the long-duration-energy-storage problem could be the caveman stuff,” Craig said. Batteries depend on “pretty sophisticated electrochemistry that quickly gets outside of what I understand. And yet the solutions may be picking up heavy stuff with cranes, picking up the earth with a hydraulic jack. I think there’s some fellas in Nevada that are putting rocks in a train and rolling it uphill, then they come back down. Like, Fred Flintstone would be comfortable with most of this stuff. It could be the way.”

What about just storing energy by storing hydrogen? And then “burning” it (to produce water) when power is needed?
Also, really liked the “physicality” of most of the energy storage approaches. Seems to be a different kind of high-tech here.
What to Know About Disinfecting and Cleaning Surfaces – The New York Times
June 4, 2022Is there a way of selectively killing just the “bad” microbes on surfaces, while leaving only the “good” ones?

“The bottom line: We germaphobes can still delight in killing germs, but perhaps not all of them. When I need to clean a spill, I’ll use soap and water or a gentle cleaning spray, not a disinfectant. But after handling raw meat, or when a family member is ill, I’ll reach for the stronger stuff to clean contaminated surfaces, and I’ll make sure to let it sit long enough to work, with the windows open. And while I wait, maybe I’ll have the chance to tidy my house, too.” “}}

Why Masks Work, but Mandates Haven’t – The New York Times
June 4, 2022I liked both these pieces & do agree with their premises. It’s amazing how much the public-health “messaging” on N95 masks has changed from ’20 to ’22. Yet the mask’s underlying physics & resulting efficacy hasn’t changed at all.

Old experiment, new tricks
In the latest work, Kotwal and his collaborators aimed to take the most precise measurement ever of the W’s mass. The data had all been collected by 2011, when Fermilab’s Tevatron — a 6-kilometre-long circular machine that collided protons with antiprotons and was once the world’s most powerful accelerator — shut down. But the latest measurement would not have been possible back then, says Kotwal. Instead, it is the result of a steady improvement of techniques in data analysis, as well as the particle-physics community’s improved understanding of how protons and antiprotons behave in collisions. “Many of the techniques to achieve that kind of precision we had not even learned about by 2012.”
The team looked at roughly four million W bosons produced inside the CDF detector between 2002 and 2011 — a data set four times larger than the group used in an early measurement in 20122. The researchers calculated the energy of each decay electron by measuring how its trajectory bent in a magnetic field. One painstaking advance over the past decade improved the resolution of the trajectories from roughly 150 micrometres to less than 30 micrometres, says Kotwal.
