… a zatiaľ v našej kúpeľni

Kým som sa ja minulý týždeň hrala s deťmi na počítače (nie na počítači!) na Žilinskej detskej univerzite, u nás v kúpeľni sa začali diať veci:

Včera vo veku 40 rokov na rakovinu zomrela Maryam Mirzakhani, matematička iránskeho pôvodu, jediná žena, ktorá dostala Fieldsovu medailu (keď sa dávali naposledy, v roku 2014). Mala českého manžela a malú dcéru.

To her dismay, Mirzakhani did poorly in her mathematics class that year. Her math teacher didn’t think she was particularly talented, which undermined her confidence. At that age, “it’s so important what others see in you,” Mirzakhani said. “I lost my interest in math.” The following year, Mirzakhani had a more encouraging teacher, however, and her performance improved enormously. “Starting from the second year, she was a star,” Beheshti said.

A Path Less Taken to the Peak of the Math World

When you teach, you do something useful. When you do research, most days you don’t.

That Huh would achieve this status after starting mathematics so late is almost as improbable as if he had picked up a tennis racket at 18 and won Wimbledon at 20. It’s the kind of out-of-nowhere journey that simply doesn’t happen in mathematics today, where it usually takes years of specialized training even to be in a position to make new discoveries. Yet it would be a mistake to see Huh’s breakthroughs as having come in spite of his unorthodox beginning. In many ways they’re a product of his unique history — a direct result of his chance encounter, in his last year of college, with a legendary mathematician who somehow recognized a gift in Huh that Huh had never perceived himself.

You Don’t Need Blue Apron to Teach You to Turn On Your Oven

Whenever I write a recipe for a magazine or newspaper my editors demand more measurements and cooking times. This phony precision undermines the heart, and joy, of cooking. Chefs sample their dishes multiple times as they cook because cooking happens by taste and by eye, not by time and temperature. Baking is the fussy one where you need measurements, while cooking is for slobs like me.

Does that look like enough pasta? Does this taste as salty as you like? That sauce looks thin — let’s throw in some more tomatoes. People become dependent on cooking times and temperatures because they don’t understand how cooking works, they know only how to follow a recipe.

The tragedy of men

The biggest problem with masculinity, Perry proffers, is that it’s based on a model that’s several thousands of years old, when survival depended on physical strength and male power. Or, as he puts it, “masculinity is to chase things and fight things and to fuck. Everything else is a bit of a mismatch.” This framework for men has remained remarkably persistent even as society has evolved past it, with modern jobs and relationships requiring a very different set of skills. Feminism, Perry observes, is forward-thinking, wondering how women can change themselves and their lives for the better. But masculinity is regressive, always “harking back to some mythical golden age (for men), when men were ‘men.’” The easiest thing in the world to sell to men who feel disenfranchised from modern life, he says, is nostalgia—a promise that the world can change to fit them rather than the other way around. That men can be great again.

what bullets do to bodies

Early in my medical training, I learned that it is not the bullet that kills you, but the path the bullet takes. A non-expanding (or full-metal-jacket) bullet often enters the body in a straight line. Like a knife, it damages the organs and tissues directly in its path, and then it either exits the body or, if it is traveling at a slower velocity, is stopped by bone, tissue or skin.

This is in contrast to expanding bullets, especially if shot from an assault rifle, which can discharge bullets much faster than a handgun. Once they enter the body, they fragment and explode, pulverizing bones, tearing blood vessels and liquefying organs…

Two years ago, a group of doctors wrote in the Annals of Internal Medicine: “It does not matter whether we believe that guns kill people or that people kill people with guns — the result is the same: a public health crisis.” In the war zone of the E.R., we don’t see partisanship or politics. We see the devastation that happens when our society normalizes tools of total bodily destruction.

este raz (dlhšie a ťažké čítanie)… a tu je to celé v dvoch vetách

She started talking about the 2012 murder of 20 schoolchildren and six adults at Sandy Hook Elementary School. Goldberg said that if people had been shown the autopsy photos of the kids, the gun debate would have been transformed. “The fact that not a single one of those kids was able to be transported to a hospital, tells me that they were not just dead, but really really really really dead.

Greetings, E.T. (Please Don’t Murder Us.)

The anti-METI movement is predicated on a grim statistical likelihood: If we do ever manage to make contact with another intelligent life-form, then almost by definition, our new pen pals will be far more advanced than we are. The best way to understand this is to consider, on a percentage basis, just how young our own high-tech civilization actually is. We have been sending structured radio signals from Earth for only the last 100 years. If the universe were exactly 14 billion years old, then it would have taken 13,999,999,900 years for radio communication to be harnessed on our planet. The odds that our message would reach a society that had been tinkering with radio for a shorter, or even similar, period of time would be staggeringly long. Imagine another planet that deviates from our timetable by just a tenth of 1 percent: If they are more advanced than us, then they will have been using radio (and successor technologies) for 14 million years. Of course, depending on where they live in the universe, their signals might take millions of years to reach us. But even if you factor in that transmission lag, if we pick up a signal from another galaxy, we will almost certainly find ourselves in conversation with a more advanced civilization.

It is this asymmetry that has convinced so many future-minded thinkers that METI is a bad idea. The history of colonialism here on Earth weighs particularly heavy on the imaginations of the METI critics. Stephen Hawking, for instance, made this observation in a 2010 documentary series: ‘‘If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans.’’ David Brin echoes the Hawking critique: ‘‘Every single case we know of a more technologically advanced culture contacting a less technologically advanced culture resulted at least in pain.’’

Wrestling with the METI question suggests, to me at least, that the one invention human society needs is more conceptual than technological: We need to define a special class of decisions that potentially create extinction-level risk. New technologies (like superintelligent computers) or interventions (like METI) that pose even the slightest risk of causing human extinction would require some novel form of global oversight. And part of that process would entail establishing, as Denning suggests, some measure of risk tolerance on a planetary level. If we don’t, then by default the gamblers will always set the agenda, and the rest of us will have to live with the consequences of their wagers.

America made me a feminist

In America, a woman’s body seemed to belong to everybody but herself. Her sexuality belonged to her husband, her opinion of herself belonged to her social circles, and her uterus belonged to the government. She was supposed to be a mother and a lover and a career woman (at a fraction of the pay) while remaining perpetually youthful and slim. In America, important men were desirable. Important women had to be desirable. That got to me.

Sci-Hub Ordered to Pay $15 Million in Piracy Damages

Elsevier says: the Sci-Hub activity ’causes irreparable injury to Elsevier, its customers and the public’ and US court agreed. That feels like a perfect crime. If you want to cause an irreparable injury to American public, what do you have to do? Now we know the answer: establish a website where they can read research articles for free,” she adds.

Previously, Elbakyan already confirmed to us that, lawsuit or not, the site is not going anywhere.
