Riding full circle on a paternoster
"A paternoster or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two persons) that move slowly in a loop up and down inside a building without stopping. Passengers can step on or off at any floor they like.

I'm slightly obsessed with these quite dangerous 1970s constructions....

A Controversial Virus Study Shows Flaws in How Science Is Done - The Atlantic
Absent clearer guidelines, the burden falls on the scientific enterprise to self-regulate—and it isn’t set up to do that well. Academia is intensely competitive, and “the drivers are about getting grants and publications, and not necessarily about being responsible citizens,” says Filippa Lentzos from King’s College London, who studies biological threats. This means that scientists often keep their work to themselves for fear of getting scooped by their peers. Their plans only become widely known once they’ve already been enacted, and the results are ready to be presented or published. This lack of transparency creates an environment where people can almost unilaterally make decisions that could affect the entire world.

Take the horsepox study [the main topic of this article]. Evans was a member of a World Health Organization committee that oversees smallpox research, but he only told his colleagues about the experiment after it was completed. He sought approval from biosafety officers at his university, and had discussions with Canadian federal agencies, but it’s unclear if they had enough ethical expertise to fully appreciate the significance of the experiment. “It’s hard not to feel like he opted for agencies that would follow the letter of the law without necessarily understanding what they were approving,” says Kelly Hills, a bioethicist at Rogue Bioethics.

She also sees a sense of impulsive recklessness in the interviews that Evans gave earlier this year. Science reported that he did the experiment “in part to end the debate about whether recreating a poxvirus was feasible.” And he told NPR that “someone had to bite the bullet and do this.” To Hills, that sounds like I did it because I could do it. “We don’t accept those arguments from anyone above age 6,” she says.

Structural Integrity | 99% Invisible
'The student (who has since been lost to history) was studying Citicorp Center as part of his thesis and had found that the building was particularly vulnerable to quartering winds (winds that strike the building at its corners). Normally, buildings are strongest at their corners, and it’s the perpendicular winds (winds that strike the building at its face) that cause the greatest strain. But this was not a normal building.

LeMessurier had accounted for the perpendicular winds, but not the quartering winds. He checked the math, and found that the student was right. He compared what velocity winds the building could withstand with weather data, and found that a storm strong enough to topple Citicorp Center hits New York City every 55 years. But that’s only if the tuned mass damper, which keeps the building stable, is running. LeMessurier realized that a major storm could cause a blackout and render the tuned mass damper inoperable. Without the tuned mass damper, LeMessurier calculated that a storm powerful enough to take out the building his New York every sixteen years.'

The Overprotected Kid - The Atlantic
Great article.
There is a big difference between avoiding major hazards and making every decision with the primary goal of optimizing child safety (or enrichment, or happiness). We can no more create the perfect environment for our children than we can create perfect children. To believe otherwise is a delusion, and a harmful one; remind yourself of that every time the panic rises.
