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.

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.

write less code

but the best code is no code at all. Every new line of code you willingly bring into the world is code that has to be debugged, code that has to be read and understood, code that has to be supported… If you love writing code– really, truly love to write code– you’ll love it enough to write as little of it as possible.

I have to say that as I look at the plots above, I’m struck by their similarity to plots for physical processes like chemical reactions. It’s as if all those humans, with all the complexities of their lives, still behave in aggregate a bit like molecules—with certain “reaction rates” to enter into relationships, marry, etc.

A Sydney mother’s stand against homework

Free play is usually the first activity to be pushed down the priority list. It’s infuriatingly unstructured. It can’t be scheduled within neat half-hour blocks.  It relies on the alchemy of a couple of kids, space and make-believe. It doesn’t seem to achieve anything.

But it does, and I will fight to protect that precious time.

It’s also important that my kids help set the table for dinner and entertain their baby brother. I think this falls under the key learning area of “life skills”.

And the most valuable literacy ‘homework’ of all? Reading a book for sheer pleasure – preferably flopped on the lounge. Now that’s a lifetime habit to encourage.

What’s surprising is how little I have to press my case with the teachers during my annual homework meeting. They nod in sympathy at my nervously delivered spiel. They know how much kids need to rest and reboot. But they all say the same line: “The other parents would complain if we didn’t give homework.”
