Dobre mu to chodí

Kika išla do školy v prírode do Nízkych Tatier, my ostatní na výlet do Vysokých. 

Počasie sme mali ukážkové a povedali sme si, že skúsime s Kubinom vyliezť na Téryho chatu.

Na konci doliny Kuba celkom pobavilo, že ide po snehu v kraťasoch.

Kúsok pod chatou síce zahlásil, že už mu stačilo a ideme naspäť, ale ukecali sme ho, že radšej ideme na chatu na obed.

Chvíľu sme poobdivovali zamrznuté pleso

Cestou dolu trochu poupratovali rozhádzané skaly

A kochali sa výhľadom:

Na druhý deň Kubino zahlásil, že chce trochu menší výlet. Chvíľu sme dumali, ale nakoniec sme opäť štartovali zo Smokovca vláčikom a išli po červenej na Skalnaté pleso. Tam sa nám veľmi nepáčilo (Skalnatá chata zavretá, nanič J&T bufet, vysekaná kosodrevina, kopa turistov vyvezených lanovkou) ale výhľad na Lomnický štít bol dobrý.

Týchto pár dní bolo zaujímavých ešte aj iným spôsobom. Kubo rozprával a rozprával a rozprával. Pusa sa mu nezastavila celý čas, čo sme išli. Keď je s nami Kika, tak sa dostane k slovu pomenej a teraz mal všetko poslucháčstvo len pre seba. Ale Kiku spomínal každú chvíľu a plánoval, ako do Tatier nabudúce pôjdeme aj s ňou.

Pár rozdielov

To isté miesto po piatich rokoch. 

Len šachista akosi vyrástol. A šachovnica vybledla.

Hričovský hrad

Postupne ho opravujú, takže sme ho našli v o kúsok lepšom stave, ako bol pred pár rokmi, keď sme tu boli naposledy. Lezenia pre deti tak akurát a zhora sme dovideli až na Rozsutce, na ktorých sa v tom čase venčil náš alfa tím.

Torching the Modern-Day Library of Alexandria

The stations—which didn’t so much scan as photograph books—had been custom-built by Google from the sheet metal up. Each one could digitize books at a rate of 1,000 pages per hour. The book would lie in a specially designed motorized cradle that would adjust to the spine, locking it in place. Above, there was an array of lights and at least $1,000 worth of optics, including four cameras, two pointed at each half of the book, and a range-finding LIDAR that overlaid a three-dimensional laser grid on the book’s surface to capture the curvature of the paper. The human operator would turn pages by hand—no machine could be as quick and gentle—and fire the cameras by pressing a foot pedal, as though playing at a strange piano. […]

It was strange to me, the idea that somewhere at Google there is a database containing 25-million books and nobody is allowed to read them. […] It’s there. The books are there. People have been trying to build a library like this for ages—to do so, they’ve said, would be to erect one of the great humanitarian artifacts of all time—and here we’ve done the work to make it real and we were about to give it to the world and now, instead, it’s 50 or 60 petabytes on disk, and the only people who can see it are half a dozen engineers on the project who happen to have access because they’re the ones responsible for locking it up.

I asked someone who used to have that job, what would it take to make the books viewable in full to everybody? I wanted to know how hard it would have been to unlock them. What’s standing between us and a digital public library of 25 million volumes?

You’d get in a lot of trouble, they said, but all you’d have to do, more or less, is write a single database query. You’d flip some access control bits from off to on. It might take a few minutes for the command to propagate.

Neuralink and the Brain’s Magical Future

Because, as the human history case study suggests, when there’s something on the planet way smarter than everyone else, it can be a really bad thing for everyone else. And if AI becomes the new thing on the planet that’s way smarter than everyone else, and it turns out not to clearly belong to us—it means that it’s its own thing. Which drops us into the category of “everyone else.” […]

He sees it as only a matter of time before superintelligent AI rises up on this planet—and when that happens, he believes that it’s critical that we don’t end up as part of “everyone else.” That’s why, in a future world made up of AI and everyone else, he thinks we have only one good option: To be AI. […]

The pace of progress in this direction matters a lot. We don’t want to develop digital superintelligence too far before being able to do a merged brain-computer interface.

The Gene, An Intimate History

Od tohto pána som pred dvoma rokmi čítala “životopis” rakoviny – knižku Emperor of all maladies. Natoľko sa mi páčila, že keď som zistila, že napísal ďlašiu knihu, tak som ju tiež kúpila. A nesklamal. Táto kniha je o génoch, o tom, čo si ľudia o nich kedysi mysleli, čo a ako sa o nich dodnes zistilo, filozofovanie o tom, prečo je to jeden z najnebezpečnejších a zároveň najúžasnejších objavov a nakuknutie do možnej budúcnosti. 

Pár úryvkov na zamyslenie a na namotanie sa:

Consider the genesis of a single-celled embryo produced by the fertilization of an egg by a sperm. The genetic material of this embryo comes from two sources: paternal genes (from sperm) and maternal genes (from eggs). But the cellular material of the embryo comes exclusively from the egg; the sperm is no more than a glorified delivery vehicle for male DNA—a genome equipped with a hyperactive tail. Aside from proteins, ribosomes, nutrients, and membranes, the egg also supplies the embryo with specialized structures called mitochondria. These mitochondria are the energy-producing factories of the cell; they are so anatomically discrete and so specialized in their function that cell biologists call them “organelles”—i.e., mini-organs resident within cells. Mitochondria, recall, carry a small, independent genome that resides within the mitochondrion itself—not in the cell’s nucleus, where the twenty-three pairs of chromosomes (and the 21,000-odd human genes) can be found. The exclusively female origin of all the mitochondria in an embryo has an important consequence. All humans—male or female—must have inherited their mitochondria from their mothers, who inherited their mitochondria from their mothers, and so forth, in an unbroken line of female ancestry stretching indefinitely into the past. (A woman also carries the mitochondrial genomes of all her future descendants in her cells; ironically, if there is such a thing as a “homunculus,” then it is exclusively female in origin—technically, a “femunculus”?) Now imagine an ancient tribe of two hundred women, each of whom bears one child. If the child happens to be a daughter, the woman dutifully passes her mitochondria to the next generation, and, through her daughter’s daughter, to a third generation. But if she has only a son and no daughter, the woman’s mitochondrial lineage wanders into a genetic blind alley and becomes extinct (since sperm do not pass their mitochondria to the embryo, sons cannot pass their mitochondrial genomes to their children). Over the course of the tribe’s evolution, tens of thousands of such mitochondrial lineages will land on lineal dead ends by chance, and be snuffed out. And here is the crux: if the founding population of a species is small enough, and if enough time has passed, the number of surviving maternal lineages will keep shrinking, and shrinking further, until only a few are left. If half of the two hundred women in our tribe have sons, and only sons, then one hundred mitochondrial lineages will dash against the glass pane of male-only heredity and vanish in the next generation. Another half will dead-end into male children in the second generation, and so forth. By the end of several generations, all the descendants of the tribe, male or female, might track their mitochondrial ancestry to just a few women. For modern humans, that number has reached one: each of us can trace our mitochondrial lineage to a single human female who existed in Africa about two hundred thousand years ago. She is the common mother of our species. We do not know what she looked like, although her closest modern-day relatives are women of the San tribe from Botswana or Namibia. I find the idea of such a founding mother endlessly mesmerizing. In human genetics, she is known by a beautiful name — Mitochondrial Eve.

… the largest “negative eugenics” project in human history was not the systemic extermination of Jews in Nazi Germany or Austria in the 1930s. That ghastly distinction falls on India and China, where more than 10 million female children are missing from adulthood because of infanticide, abortion, and neglect of female children.

McKusick’s belief in this paradigm – the focus on disability rather than abnormalcy – was actualized in the treatment of patients in his clinic. Patients with dwarfism, for instance, were treated by an interdisciplinary team of genetic counselors, neurologists, orthopedic surgeons, nurses, and psychiatrists trained to focus on specific disabilities of persons with short stature. Surgical interventions were reserved to correct specific deformities as they arose. The goal was not to restore “normalcy” – but vitality, joy, and function. […] And here too “fitness” could not be judged in absolutes. Rather the lack of fitness – illness in colloquial terms – was defined by the relative mismatch between an organism and environment.

Sezamko v Rajeckej Lesnej

V zime bol Sezamko u nás na fakulte, teraz sme sa vybrali na víkendovku do Rajeckej Lesnej. Až na prehánkové počasie to bola paráda. Počítali sme príklady:

Rozmýšľali na prednáškach:


Túlali sa po lese:

Mokli v daždi:


Užívali si slniečko:

Bývali v chatkách:

Stretli rozprávkové bytosti (hádajte, kto som):

A bolo nám veľmi fajn:

Takže ak poznáte terajšie štvrtáčky, štvrtákov, piatakov a piatačky, tak im v septembri odporučte Sezamka, radi sa s nimi na podobnej akcii stretneme budúci rok.

Omeletové muffiny/muffinové omelety

Kika má obyčajne na desiatu chlieb alebo žemľu so syrom alebo salámou alebo nejakou zeleninou a k tomu nejaké ovocie. Ak máme upečený koláč, tak z neho dostane kúsok namiesto žemle. Párkrát už boli jablkové lievance, čo zvýšili od večere. Občas nejaká šatôčka alebo osie hniezdo. Sťažovala sa, že nuda, stále to isté. A to ja som rada, že ráno vôbec s polozalepenými očami nachystám niečo, čo nie je 7days croissant (jej predstava ideálnej desiaty). A tak v rámci diverzifikácie portfólia sa u nás už párkrát objavili omeletové muffiny. 

12 malých vajec
zelenina (brokolica, mladá cibuľka, …)
šunka (nemusí byť)
majoránka/bazalka/provensálske bylinky
olej na vymastenie košíčkov

Do plechu na muffiny naukladáme papierové košíčky. Poriadne ich vymastíme. Približne do dvoch tretín ich naplníme nadrobno nakrájanými kúskami zeleniny, húb, šunky. Potom do každého košíčka vytresneme jedno vajíčko. Ak sú veľké, tak ich treba rozdeliť, lebo inak muffiny vykypia. Do každého košíčka dáme trochu byliniek a prípadne štipku soli. Je fajn ešte každý košíček trochu vidličkou alebo lyžičkou premiešať. Pečieme v rúre na 200C, asi 20 minút, kým nie sú krásne zlatisté.


  • Asi je jasné, že toto sa nerobí ráno pred odchodom do školy. Ale dobrá správa je, že v chladničke v pohode môžu ostať pár dní.
  • Muffiny sú veľmi fajn, akurát ešte treba vyriešiť jeden technický problém. Strašne sa lepia na tie papierové košíčky. Trochu menej, keď ich vymastím, ale stále dosť. Zatiaľ som si netrúfla vymastiť/vysypať strúhankou priamo plech. Ak prídem na nejaké vylepšováky, tak ich sem dopíšem a budem vďačná za vaše, ak na ne prídete skôr.

our mothers as we never saw them

The old photos of her are even more compelling than the stories because they’re a historical record, carrying the weight of fact, even if the truth there is slippery: the trick of an image, and so much left outside the frame. These photos serve as a visual accompaniment to the myths. Because any story about your mother is part myth, isn’t it?

Unless it’s a pie that is a pudding, like a mince pie, which doesn’t involve mince, which is meat that’s been minced, but does involve mincemeat, which doesn’t involve meat. You could put what you think of as pudding on this type of pie, which is a pudding.

Study: Accomplished female scientists often overlooked

One, the composition of the organizing committee matters. I looked at all the neuroimmunology conferences held in 2016 worldwide, and I found that as you approach 50 percent women on the organizing committee, you approach 50 percent female invited speakers. So if you want gender parity in speakers, first you need to include more women in organizing and planning committees. Two, speaking out about gender balance makes a difference.

Malý výlet, veľká spoločnosť:

Vrátane štvornohého kamaráta Noxa:

Tam ideme:

Na konci sme si s Kubom a Noxom dali preteky. (Kuba treba každý deň niekde vybehať, lebo inak doma večer robí koliečka okolo kuchyne. Koniec koncov, Noxa tiež, lebo takýto čistokrvný husky vraj ocení svojich pár kilometrov denne.) My s Kubom sme samozrejme nemali šancu. Ani druhý raz, keď sme začali s náskokom. Kubina, ktorý je z občasného venčenia zvyknutý akurát tak na susedovie starú dámu, jazvečicu Lesiu, to celkom prekvapilo.
