“The King’s life is moving peacefully towards its close,” was the final notice issued by George V’s doctor,Lord Dawson, at 9.30pm on the night of 20 January 1936. Not long afterwards, Dawson injected the king with 750mg of morphine and a gram of cocaine – enough to kill him twice over – in order to ease the monarch’s suffering, and to have him expire in time for the printing presses of the Times, which rolled at midnight.
…three of the Queen’s last four prime ministers were born after she came to the throne.
The common element in all of this is knowing how to tell a story. Contrary to popular misconceptions about science and technology, a good piece of technical work is not a disembodied sequence of formulas and calculations, but rather is part of a narrative that has a long plot line and a large cast of characters.
There have been moves from five to six minutes before, to which this is proportional. Also, the clock was at 11:57; it’s only been at 11:58 once before, after the US and Soviet Union did thermonuclear tests in close temporal proximity in 1953. So unless they want to say it is literally the worst it has ever been, two and a half minutes to midnight it is.
The new outside-of-school math programs like the Russian School vary in their curricula and teaching methods, but they have key elements in common. Perhaps the most salient is the emphasis on teaching students to think about math conceptually and then use that conceptual knowledge as a tool to predict, explore, and explain the world around them. There is a dearth of rote learning and not much time spent applying a list of memorized formulas. Computational speed is not a virtue.
eduScrum (a ešte raz) – Mišo teraz kvôli novej práci študuje všetko možné o Scrum-e, stand-up meetingoch, … a ako to už chodí, podobné veci majú tendenciu sa zjavovať z rôznych smerov, a u nás na fakulte začali chodiť linky na eduScrum
učiteľ už nie je len postavička stojaca pred tabuľou a prednášajúca učivo apatickým deťom hrajúcim sa na mobiloch. Trieda je rozdelená do skupín a žiaci sa učia spoločne. Študujú novú teóriu, robia cvičenia, sú nútení spolupracovať a samostatne riešiť problémy. Dokonca si sami určujú, čo budú robiť na hodine a čo im ostane na domácu úlohu.
Now, instead of a precise and versatile set of scissors, which can cut any gene you want, you have a precise and versatile delivery system, which can control any gene you want. You don’t just have an editor. You have a stimulant, a muzzle, a dimmer switch, a tracker.
Bolo veľmi dobre a zaujímavo a dúfam, že aj na budúci rok sa nám podarí ju zorganizovať. Ak ste alebo poznáte nejakých doktorandov a doktorandky, ktorí robia niečo s matematikou, povedzte im nech nám o tom prídu začiatkom budúceho roku porozprávať. Tí tohtoroční odchádzali veľmi spokojní a s kopou nových nápadov.

“Female pain might be perceived as constructed or exaggerated”: We saw this from the moment we entered the hospital, as the staff downplayed Rachel’s pain, even plain ignored it. In her essay, Jamison refers back to “The Girl Who Cried Pain,” a study identifying ways gender bias tends to play out in clinical pain management. Women are “more likely to be treated less aggressively in their initial encounters with the health-care system until they ‘prove that they are as sick as male patients,’” the study concludes—a phenomenon referred to in the medical community as “Yentl Syndrome.”
In 1975, a San Diego woman named Marjorie Rice read in her son’s Scientific American magazine that there were only eight known pentagonal shapes that could entirely tile, or tessellate, a plane. Despite having had no math beyond high school, she resolved to find another. By 1977, she’d discovered not just one but four new tessellations — a result noteworthy enough to be published the following year in a mathematics journal.
…the maximum speed has rarely attracted the interest of physicists, despite its remarkable scalingproperty; it is roughly proportional to length throughout nearly the whole range of running and swimming organisms. We propose a simple order-of-magnitude interpretation of this ubiquitous relationship, based on physical properties shared by life forms of very different body structure and varying by more than 20 orders of magnitude in body mass.
dobrá fotka z ISS – vysvietené Times Square… a zaujímavé, ako viac svieti Hoboken (tam sme pár rokov bývali) oproti ostatným mestečkám v New Jersey
Turner and Constable are not alone in the pantheon of epic rivalries between creative giants. Isaac Newton and Gottfried Leibniz, two of the most brilliant mathematicians and thinkers of the 17th century, laid claim to the development of calculus, the mathematical study of change. Thomas Edison and Nikola Tesla both invented electrical systems in the 1880s. Steve Jobs and Bill Gates went head-to-head as pioneers of the computer age. If you Google almost any famous figure along with ‘rivalry’, you’ll find some interesting results.
Friends call Constable Collins Rain Man or Yoda or simply The Oracle. But to Scotland Yard, London’s metropolitan police force, he is known as a “super recognizer.” He has a special gift of facial recall powers that enables him to match even low-quality and partial imagery to a face he has seen before, on the street or in a database and possibly years earlier. The last time he had come face to face with Mr. Prince was during a fleeting encounter in 2005.
Pri príležitosti včerajšieho sviatku som si prečítala knihu The Martian (napísal Andy Weir). Dobré, rýchle, miestami vtipné čítanie o astronautovi, ktorého omylom nechali na Marse.
I’ve been thinking about laws on Mars. Yeah, I know, it’s a stupid thing to think about, but I have a lot of free time.
There’s an international treaty saying no country can lay claim to anything that’s not on Earth. And by another treaty, if you’re not in any country’s territory, maritime law applies. So Mars is “international waters.” NASA is an American non-military organization, and it owns the Hab. So while I’m in the Hab, American law applies. As soon as I step outside, I’m in international waters. Then when I get in the Rover, I’m back to American law.
Here’s the cool part: I will eventually go to Schiaparelli crater and commandeer the Ares 4 lander. Nobody explicitly gave me permission to do this, and they can’t until I’m aboard Ares 4 and operating the comm system. After I board Ares 4, before talking to NASA, I will take control of a craft in international waters without permission. That makes me a pirate! A Space Pirate!
Onedlho bude aj film:
Čo na tej knihe bolo najviac cool, bola všetka tá improvizácia, ktorú Mark musel robiť. Veľmi mi to pripomínalo jednu matematickú prednášku, ktorú som videla, inšpirovanú touto prácou: Street-fighting mathematics, The Art of Educated Guessing and Opportunistic Problem Solving.
In problem solving, as in street fighting, rules are for fools: do whatever works—don’t just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.
Compressional waves are fast-moving, high-frequency waves, audible to dogs and certain other animals but experienced by humans only as a sudden jolt. They are not very harmful, but they are potentially very useful, since they travel fast enough to be detected by sensors thirty to ninety seconds ahead of other seismic waves. That is enough time for earthquake early-warning systems, such as those in use throughout Japan, to automatically perform a variety of lifesaving functions: shutting down railways and power plants, opening elevators and firehouse doors, alerting hospitals to halt surgeries, and triggering alarms so that the general public can take cover. The Pacific Northwest has no early-warning system. When the Cascadia earthquake begins, there will be, instead, a cacophony of barking dogs and a long, suspended, what-was-that moment before the surface waves arrive.
Misty Copeland – opäť raz jedna žena, ktorej povedali, že jej telo nevyzerá tak, “ako by malo vyzerať”
The Fields Medal is given every four years, and several can be awarded at once. The other recipients this year are Artur Avila of the National Institute of Pure and Applied Mathematics in Brazil and the National Center for Scientific Research in France; Manjul Bhargava of Princeton University; and Martin Hairer of the University of Warwick in England.
The 52 medalists from previous years were all men.
While women have reached parity in many academic fields, mathematics is still dominated by men, who earn about 70 percent of the doctoral degrees. The disparity is even more striking at the highest echelons. Since 2003, the Norwegian Academy of Science and Letters has awarded the Abel Prize, recognizing outstanding mathematicians with a monetary award of about $1 million; all 14 recipients so far are men. No woman has won the Wolf Prize in Mathematics, another prestigious award.
