Thanksgiving in Mongolia (ťažké čítanie, obzvlášť pre práve tehotných)

I knew that a child would make life as a professional explorer largely impossible. But having a kid seemed in many ways like the wildest trip of all.

But the truth is, the ten or twenty minutes I was somebody’s mother were black magic. There is no adventure I would trade them for; there is no place I would rather have seen. Sometimes, when I think about it, I still feel a dark hurt from some primal part of myself, and if I’m alone in my apartment when this happens I will hear myself making sounds that I never made before I went to Mongolia. I realize that I have turned back into a wounded witch, wailing in the forest, undone.

Most of the time it seems sort of O.K., though, natural. Nature. Mother Nature. She is free to do whatever she chooses.

How do you get poor kids to apply to great colleges

You open the envelope and find a personalized letter from the College Board, the SAT people. It says that, because your grades and scores are in the top 10 percent of test takers in the nation, there are colleges asking you to apply. Princeton, Harvard, Emory, Smith—there’s a long list, places you’ve read about in books. And here’s an even more shocking page: It says the College Board somehow knows your mom can’t afford to pay for your schooling so it will be free. There’s even a chart comparing costs to these schools and your community college and the state campus, breaking them down in black and white—it turns out your mom would have to pay more to send you to the community college than to Princeton or Harvard. To top it all off, clipped to the packet are eight no-cost vouchers to cover your application fees!

neznášam, keď mi hovoria, že som dobrý otec

With no context — and no real basis for interpretation — the act of labeling someone a “good dad” suggests that most dads are, by our very nature as fathers, somehow less than “good.” That we don’t care. That we’re mostly cruel. What’s more, the phrase evinces a heinous double standard: It’s not like strangers compliment women as being “good moms” for doting, loving and doing normal mom stuff.

friends you can count on – populárna matematika na dnešný deň

For any network where some people have more friends than others, it’s a theorem that the average number of friends of friends is always greater than the average number of friends of individuals. This phenomenon has been called the friendship paradox.

veda pre dievčatá

Celkom slušný brainwashing na 45 sekúnd trvajúci klip. Ale aby som zasa len nekritizovala, snaha je to záslužná a činnosť osožná- teda dúfajme, že kampaň sa na ďalších úrovniach podobným zhovadilostiam vyhne a bude reprezentovať prírodné vedy, technické odbory a matematiku ako to, čím naozaj sú: fascinujúce, nekonečne zaujímavé a hlavne žiadané. Potenciál tu vidím veľký, keďže majú na svojej strane mnoho žien, ktoré sa reálne venujú spomínaným odborom a nech už povedia dievčatám čokoľvek, bude to pravdepodobne prvý krát v živote, keď mladý mozog pri slove geológ, mikrobiológ, astrofyzik, fyzik, informatik, vedec atď. bude spracovávať obraz mladej ženy a asi prvý krát to nebude Marie Curie Sklodowska.

Edita Angyalová: S partnerkou sa snažíme byť dobrými rodičmi

Podporili by ste teda možnosť adopcií pre homosexuálne páry?
„Nech sa s tým spoločnosť vyrovná spôsobom a v rozsahu, na aký je pripravená. No zvážte, čo všetko sme my riešili, kým sme dieťa mali. Myslíte, že priemerný pár takto zodpovedne zvažuje každý detail, čo spraví, keď na svet prinesie dieťa? Toľko vecí sme sa snažili usporiadať správne a urobiť ich dobre. Myslím si, že žijeme najlepšie, ako sa dá, robíme všetko preto, aby bol šťastný, plnohodnotný občan, plnohodnotný človek.“

čo potrebujú malé deti

An Oregon State study reported on 430 children who were followed from preschool until age 25. The study, published online earlier this month in Early Childhood Research Quarterly, looked at several factors, including early reading and math skills, along with other cognitive skills, to see which were ultimately most influential in college success. It turns out that a child’s ability at age 4 to pay attention and complete a task, the very skills learned in game play, were the greatest predictors of whether he or she finished college by age 25.

interaktívne učenie

Thus Mazur begins a class with a student-sourced question, then asks students to think the problem through and commit to an answer, which each records using a handheld device (smartphones work fine), and which a central computer statistically compiles, without displaying the overall tally. If between 30 and 70 percent of the class gets the correct answer (Mazur seeks controversy), he moves on to peer instruction. Students find a neighbor with a different answer and make a case for their own response. Each tries to convince the other… After two or three minutes, the students vote again, and typically the percentage of correct answers dramatically improves. Then the cycle repeats.

čo robiť, keď všetci vaši priatelia začnú mať bábätká – ruská fotografka fotila spiace páry počas tehotenstva

Ja som vcelku tolerantný človek. Ale násilie voči deťom, mladým dievčatám? Keby bolo po mojom, tak vinníci by v týchto prípadoch nielen zaplatili za to, čo urobili, ale by pritom museli trpieť. Kanaďanka Amanda Todd spáchala samovraždu kvôli chlapíkovi, s ktorým sa zoznámila na internete a ktorý ju potom prenasledoval. Dvaja učitelia v Californii sexuálne zneužívali Kristen Cunnane od jej 12tich rokov, jedného za to odsúdili, druhý spáchal samovraždu, ale súd rozhodol aj o tom, že Kristen si za svoje znásilnenie môže sama. (WTF?)

A ešte zopár liniek pri príležitosti tohtotýždňových amerických prezidentských volieb:

Prezident Obama a deti (fotky)

Prezident Obama odpovedá dievčaťu, ktoré má dvoch otcov

“If you were me and you had two dads that loved each other and kids at school teased you about it, what would you do?” And guess what! Obama wrote Sophia back. His advice: “A good rule is to treat others the way you hope they will treat you. Remind your friends at school about this rule if they say something that hurts your feelings.”

Romney a ženy

ženy sú nová väčšina (ešte jedno ďakujem pre Zuz)

But in this election, it became abundantly clear that women’s issues are not fringe issues, and women are not a special interest group. Instead it was women who cast the bulk of the votes this election – 53%, and women who proved the deciding factor, breaking in Barack Obama’s favour by 11 percentage points.

It all starts in the forest. Cork oaks are harvested every nine years, once they reach maturity. It doesn’t harm the tree, and the cork bark regrows. Most cork forests are in Portugal and Spain.

That you will do things for your children (ask favors, risk embarrassment) that you would never do for yourself.

That a teenager is like something out of a horror movie — their real self is somewhere within that new and scary shell, and the trick is to keep talking to the person you know is in there. They will hear you. It just might take a few years before they acknowledge that they’ve heard.

ešte raz k Olypiáde – prečo nie sú víťazstvá Jima Thorpa stále uznané

On the second day, Thorpe’s shoes were missing. Warner hastily put together a mismatched pair in time for the high jump, which Thorpe won. Later that afternoon came one of his favorite events, the 110-meter hurdles. Thorpe blistered the track in 15.6 seconds, again quicker than Bob Mathias would run it in ’48.

On the final day of competition, Thorpe placed third and fourth in the events in which he was most inexperienced, the pole vault and javelin. Then came the very last event, the 1,500-meter run. The metric mile was a leg-burning monster that came after nine other events over two days. And he was still in mismatched shoes.

Thorpe left cinders in the faces of his competitors. He ran it in 4 minutes 40.1 seconds. Faster than anyone in 1948. Faster than anyone in 1952. Faster than anyone in 1960—when he would have beaten Rafer Johnson by nine seconds. No Olympic decathlete, in fact, could beat Thorpe’s time until 1972. As Neely Tucker of the Washington Post pointed out, even today’s reigning gold medalist in the decathlon, Bryan Clay, would beat Thorpe by only a second.

každá žena by mala cestovať sama

At the age of 27, I got in my aquamarine Honda and drove 26,000 miles around the country for five months by myself. It was foolish and lonely and 10 years later, I still think it might be the best thing I’ve ever done. I wore clothes till they were filthy and lived on baked beans and peanut butter, but the luxury of that time is unimaginable to me now, because I woke up every morning with no one’s agenda but my own. What did I want to see today? Where did I want to go?

There is a poignant scene near the end of “Wild.” Cheryl Strayed’s mother is close to death, and she tells her daughter, “I never got to be in the driver’s seat of my own life … I always did what someone else wanted me to do. I’ve always been someone else’s daughter or mother or wife. I’ve never just been me.” God, that moment cut me. Boyfriends are nice, and careers are important, but I think this is all I’ve ever been after: to just be me.

The Aims of Education

By A. N. Whitehead, 1929, 247 pages, amazon

At the beginning of this semester prof. Kriegsmann, who teaches us Asymptotics II, was gone for a few lectures and prof. Booty was filling up for him. I have to admit that the fluid flow problem that he went over with us during that time was not too interesting for me. But what caught my interest was a recommendation for this small book. It contains essays that the British mathematician Whitehead originally delivered as speeches. And some of them are extremely good and applicable even today despite the fact that they will be 100 years old soon.

Let the main ideas that are introduced into a child’s education be few and important, and let them be thrown into every combination possible. The child should make them his own and should understand their application here and now in the circumstances of his actual life. From the very beginning of his education, the child should experience the joy of discovery…

This book should both be read by teachers who want to be good teachers and by students who want to make the most of their education and understand how the learning process works and passes through different stages. The non-mathematicians should not be distracted by the math examples Whihead uses to illustrate his points, nor by his bias towards necessity to include a certain amount of mathematical curriculum into everybody’s education (which I, personally, share), because the message that he is trying to deliver is valid in all fields.

The first essay (with some math parts omitted) can be found here.
