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.

What of you just hate making dinner? 🙂 (mne tie večere až tak nevadia, ale za prečítanie to stálo)

And worst of all, as the mother-cookbooks make painfully clear, the daily work of feeding children doesn’t fall to the sages. Neither does it, notably, fall to the dads, whom the cookbooks commend for having signature dishes or being grill-masters, but not for punching the clock at breakfast, lunch and dinner. No, cooking belongs, inevitably, to the moms. I’ve tried to find outrage among my sister mothers about this reactionary development. But here’s the unkindest cut: It turns out that other women — traitorously — now like to cook. They find cooking expressive and fascinating. No one but me wants to be a born defroster anymore. “I hear you, but I like to cook,” said one feminist the last time I tried my bold association of foodism with rank misogyny.

postcards form the edge of consciousness

But the sensory experience of floating is like nothing else. The only sounds come from inside the body: the whooshing rush of each breath filling then escaping the lungs, the echoing thump of the heart in the chest. At some point (has it been five minutes? 10 minutes?), I realize I can’t tell if my eyes are open or closed. When I twitch my eyelids to check, the sound of the ensuing blink is a resonant boom. A rumbling begins somewhere behind my right ear, as if a truck is coming around the curve of my head, and as it thunders past, I realize an air bubble has been loosed from my hair. There are subtler noises as well, a regular swish like the hem of a woman’s dress brushing a marble floor—my blood circulating.

Selawood

Na úvod disclaimer. Mám šikovného známeho, ktorý predáva drevené dosky Selawood. Pri príležitosti nášho sťahovania do nového bytu a zariaďovania novej kuchyne, som jednu od neho dostala.  Toto je také verejné ďakujem a zároveň pre potenciálnych záujemcov odporúčanie. (Mimochodom, drahí moji známi, ak by ste náhodou niekto za podobnými účelmi chceli venovať peknú obývačkovú sedačku, určite sa ozvite :).)

Takže odporúčanie… doska prišla pekne zabalená, aj sa nám prihovorila (milými slovami na papieri). Je to kus bukového dreva, takže jej určite nebude hroziť to, čo mnohým tenkým doštičkám – že sa časom ohnú. To, či ju postihne druhá najväčšia pliaga krájacích dosiek – praskanie v spojoch – sa ukáže až časom, ale tipujem že nie, lebo napriek tomu, že je zjavne z troch kúskov, vyzerá že vydrží veľa. Jediné, čo sa jej dá “vytknúť” je to, že túto krásavicu nebudete dvíhať jednou rukou, aby ste z nej nožíkom zošupli do hrnca práve nakrájané dobroty. Na to je príliš ťažká a veľká. Ale to je zároveň aj jej prednosť, lebo sa aspoň nešmýka po kuchynskej linke a dáva dostatok priestoru, aby sa z nej nesypali nakrájané veci na všetky strany. A je natoľko pekná, že ju nechcem mať schovanú v skrinke.

rebelské deti? Aspoň niečo robíte správne

Most parenting books are about how to get children to do things well. By well, read obediently. When and how you – the adult – want them to do something: eat well, pee in the potty, sleep well (that’s the big one), behave well. The aim, it would seem, is to raise compliant children. Because, according to these books, obedient children = successful parents, disobedient = head hanging failures. But actually is an obedient child cause for concern or celebration? The more I thought about it, the more intrigued I became by this question. Telling someone their child is obedient is (usually) meant as a compliment. But an obedient adult? Not quite so attractive is it? We have other words for that, doormat being one of them.

súvis medzi každodennou nerovnosťou pohlaví a mierumilovnosťou krajiny?

According to the authors, the very best indicator and predictor of a state’s peacefulness is not wealth, military expenditures, or religion; the best predictor is how well its girls and women are treated. And before you start making exceptions for the U.S., think about this: Democracies with high levels of violence against women are as insecure and unstable as non-democracies. Whether a country is a democracy or not is irrelevant.

Gender is the fundamental construct for how a society understands difference. Regardless of which state we are talking about, tolerance for street harassment, rape, domestic violence, and restrictions on reproductive freedom are among several indicators of gender inequality rooted in such difference.

For me, the purpose of this challenge is not to commit to living with a certain number of things, but to discover more benefits of living with less. If it improves my life, I’ll cull the list further. If it adds stress or unnecessary hardship (a.k.a. makes me grumpy), I’ll kill the experiment.

Benfordov zákon – s akou frekvenciou sa vyskytujú jednotlivé číslice na prvom mieste u náhodných dát

Almost from the beginning, proponents of Benford’s Law have suggested that it would be a beneficial tool for fraud detection. A recent example is Mark Nigrini’s research, which showed that Benford’s Law could be used as an indicator of accounting and expenses fraud. One fraudster wrote numerous checks to himself just below US $100,000 (a policy and procedure threshold), causing digits 7, 8 and 9 to have aberrant percentages of actual occurrence in a Benford’s Law analysis. Digital analysis using Benford’s Law was also used as evidence of voter fraud in the 2009 Iranian election. In fact, Benford’s Law is legally admissible as evidence in the US in criminal cases at the federal, state and local levels.
