Putz, eu concordo. Sempre achei que o tal deficit erótico era uma contrapartida à dominância física masculina. Será que alguma de nossas amigas não faria o favor de comentar/brigar/etc?
Especialmente a última frase.
Toma idiota, que as internetes não perdoam.
Empresa: teknisa informática. Informando pra todo mundo passar longe.
Aí a gente faz 4 anos de faculdade pra isso: Trabalhar por 500 pilas por mês. E se reclamar, é mal agradecido. As empresas costumam tratar funcionário/candidato como se estivessem fazendo um favor a eles, como se não precisassem deles. E aí surgem vagas com salários ridículos como o acima e/ou com condições de trabalho degradantes. Essa mentalidade escravocrata do empresariado brasileiro está fazendo com que muita mão de obra qualificada deixe o país. E isso só tente a piorar, IMHO.
If you like a flatter design everywhere, websites with 3D buttons and other layout elements can be annoying. This neat little bookmarklet by developer Adam Schwartz promises to flatten any web page.
Basically, the bookmarklet removes background images. "Websites need to define a good background color behind their images, if they don't, you might see some unexpected things," Schwartz warns. And this has some unintended side effects, such as removing Twitter background images and making the YouTube subscribe button disappear. So try it out and see which websites it works on for you. It might make some less cluttered.
Head to the link below to get the bookmarklet and drag it to your bookmarks bar. Whenever you are on a website with 3D elements that feel like they're getting in the way, click it and it will automatically flatten the page.

It is difficult not to fall for the design creativity and layout this contemporary Swedish apartment puts on display! Located in Gothenburg, Sweden, in a beautifully renovated building, this home preserves charming details of the past, including an original turn of the century fireplace. Despite its relatively small surface of 60 square meters, the crib (initially discovered by Freshome on Alvhem) seems to have it all. A small hallway with just enough storage space leads the way towards the kitchen, living room and bedroom. Each of these interiors is personalized and exudes a welcoming feel.
Walls painted in a lovely shade of white subtly contrast the classic oak floors in the living room. The former inhabitants of the apartment decided to break down the dividing wall between the kitchen and living space, resulting in an original open floor plan. However, our favorite interior remains the bedroom, with its serenity-inspiring color palette, king-sized bed and plenty of natural light.

BEHOLD THE CONE OF SILENCE!
The US government sets up secure tents for the president and other officials to deal with classified material while traveling abroad.
Even when Obama travels to allied nations, aides quickly set up the security tent -- which has opaque sides and noise-making devices inside -- in a room near his hotel suite. When the president needs to read a classified document or have a sensitive conversation, he ducks into the tent to shield himself from secret video cameras and listening devices.
Following a several-hundred-page classified manual, the rooms are lined with foil and soundproofed. An interior location, preferably with no windows, is recommended.

<<4. While stopped, turn your wheel all the way to the right. ALL THE WAY. Don't move forward or back while doing this!>>
NÃO FAÇA ISSO. NUNCA. JAMAIS.
Parallel parking isn't hard once you've done it a few times, but it can be nerve-wracking if you're new, or trying to do it right for a driving test. Thankfully, over at Quora, Yishan Wong offers this step-by-step breakdown of how to parallel park perfectly every single time—and he's spot on.
Here's how he explains you do it:
Here are the directions, with extra "do it exactly this way"-style bolding and prompting:
- Drive around until you find a spot that looks big enough.
- Pull up even to the front car. If your cars are different lengths, line up the back of your car with the back of the front car as best you can. You don't have to be exact here.
- While stopped, turn your wheel all the way to the right. ALL THE WAY. Don't move forward or back while doing this!
- Turn around and look out the back of your car.
- Begin backing up. Your car should start turning into the spot. Don't turn your wheel away from the all-the-way-right position!
- Stop backing up when the right-front corner of the rear car is in the exact middle of your rear windshield. If you imagine a line extending backwards from your car along its centerline, you stop when the right-front corner of the rear car reaches that line.
- I said STOP.
- While stopped, turn your wheel back to the middle position.
- Back up slowly until your car just barely clears the front car, then stop again.
- Turn your wheel all the way to the left. All the way! Stay stopped while you do this.
- Now keep backing in. Don't turn your wheel away from the all-the-way-left position!
- Once your car is parallel, STOP and then turn your wheel to face forwards again.
If you do these steps exactly, your car will magically place itself into the correct position.
He's right, and if you hit the link below, he describes further why this works repeatedly. The key is to remember that parallel parking is a repeatable thing, it doesn't require judgement, it doesn't require experience, it just requires that you have a space large enough for your vehicle and you repeat the same process over and over again with as little variation as possible. In his own words:
You do not need to practice, you just need to fucking follow the directions. Parallel is not a "skill," it is more like a binary thing.
We couldn't agree more. Hit the link below to see the whole response over at Quora, or check out this previously posted graphic or this video guide for those of us who are visual learners.

pra gente pensar.
In a clarion call that will likely rival his insta-legendary "everything's amazing and nobody's happy" diatribe delivered nearly five years ago on Late Night with Conan O'Brien, comedian Louis C.K. explains — to Conan, once again — exactly why he dislikes the culture of smartphones and why he would never get one for his kids.
C.K. starts off by suggesting that smartphone usage is the reason kids today are meaner:
I think these things are toxic, especially for kids...they don't look at people when they talk to them and they don't build empathy. You know, kids are mean, and it's 'cause they're trying it out. They look at a kid and they go, 'you're fat,' and then they see the kid's face scrunch up and they go, 'oh, that doesn't feel good to make a person do that.' But they got to start with doing the mean thing. But when they write 'you're fat,' then they just go, 'mmm, that was fun, I like that.'
From there, C.K. moved on to expound on the larger issue: The negative emotional effect that smartphones have on grown-ups.
While C.K. agrees that smartphones can help create a sense of community, he believes that therein lies the problem:
You need to build an ability to just be yourself and not be doing something. That's what the phones are taking away, is the ability to just sit there. That's being a person. Because underneath everything in your life there is that thing, that empty—forever empty. That knowledge that it's all for nothing and that you're alone. It's down there.
And sometimes when things clear away, you're not watching anything, you're in your car, and you start going, 'oh no, here it comes. That I'm alone.' It's starts to visit on you. Just this sadness. Life is tremendously sad, just by being in it...
That's why we text and drive. I look around, pretty much 100 percent of the people driving are texting. And they're killing, everybody's murdering each other with their cars. But people are willing to risk taking a life and ruining their own because they don't want to be alone for a second because it's so hard.
Finally, C.K. brings it all together with an anecdote about the time he was in his car listening to a Bruce Springsteen song ("Jungleland") that made him really sad:
And I go, 'oh, I'm getting sad, gotta get the phone and write "hi" to like 50 people'...then I said, 'you know what, don't. Just be sad. Just let the sadness, stand in the way of it, and let it hit you like a truck.'
And I let it come, and I just started to feel 'oh my God,'and I pulled over and I just cried like a bitch. I cried so much. And it was beautiful. Sadness is poetic. You're lucky to live sad moments.
And then I had happy feelings. Because when you let yourself feel sad, your body has antibodies, it has happiness that comes rushing in to meet the sadness. So I was grateful to feel sad, and then I met it with true, profound happiness. It was such a trip.
The thing is, because we don't want that first bit of sad, we push it away with a little phone or a jack-off or the food. You never feel completely sad or completely happy, you just feel kinda satisfied with your product, and then you die. So that's why I don't want to get a phone for my kids.

This week's release of iOS 7 and today's iPhone 5S and 5C launch in stores mean huge numbers of people have just started using Apple's latest mobile operating system for the very first time. Much of what they're finding is equal parts thrilling, annoying—and confusing.
Developers (and other resourceful types) have had their hands on a beta version of iOS 7 all summer, so they've had plenty of time to suss out its quirks and hidden settings. But for the average user, navigating this new technicolor alternate reality without a roadmap can be unsettling—especially when strange, inexplicable things crop up.
What Is That Blue Dot?
Shortly after I started using iOS 7, I noticed a strange blue dot on some of my apps, but not all. Do these indicate some sort of alert within the app? A background process? Apps that need updating? There was no explanation.
After using the device for a little while, I realized that the blue dot only only appeared next to applications that the App Store had updated. It kicked on—without my intervention—because iOS 7 now features automatic background updating of apps, and it activated immediately when I upgraded to the new OS.
There's A Mystery "Pill" on the Lockscreen
Some users may notice a strange little item at the top center of the lockscreen (above the time). What is it? Why is it there? Well, I can answer at least the former.
It indicates that you have Notifications Center and the Today View set to appear on the lockscreen. There's also another pill at the bottom, if you've enabled Control Center to appear there as well.
Why they're there is another matter that has me stumped. These "pills" don't really do anything—though, I suppose it's nice that users have a visual target to aim for when they swipe. But they're extraneous. And just plain odd.
How Am I Supposed To Close An App Now?
Multitasking also got a makeover. Now, when you double-click the home button, an array of cards materializes representing all currently running and recently opened apps. But there's no little "x" to click to exit the program. iOS users have been trained for years to hit the "x" to nix an app, and it's suddenly gone now—which can make some users wonder how to close apps in this new environment.
Not that Apple has blocked you from shutting down apps. Simply swiping up on the application does the trick—but you need to make sure your finger's flinging the card, not the app icon.
Where The Heck Is The Weather Widget In Notifications?
Stymied by the disappearance of Weather from your pull-down Notifications Center? You're not the only one.
I updated to iOS 7 two days ago, and nary a weather forecast has shown up. I searched online, and found plenty of screencaps showing weather data—albeit in text only—sitting in other people's Notifications area. But on my iPhone 5, after two days, there was still nothing.
Drilling into Settings, I made sure Location Services was on (under Privacy) and checked that the Weather toggle was turned on. Nothing. I went into Notification Center and turned all the Today View toggles off and then back on. Still nothing.
I made one last-ditch effort. I launched the Weather app from my home screen, hoping that would jumpstart things, and then toggled everything under the Today View settings off and back on (again). Then I rebooted the phone. Success! This time, the Weather data made its triumphant return to the top of my phone.
Although I do miss the animated graphic that illustrated sunny, cloudy or rainy days, I'm grateful to have this extremely handy feature back. And I vow we'll never be parted again.
Where'd The Search Bar Go In Safari?
Search is still present in Safari, though you might not realize it at first glance.
Unified search bars are the in thing for browsers right now. Mobile Safari has been a prominent holdout, with separate windows for entering Web addresses and search queries, but that's no longer the case. Just type your queries into what used to be the URL bar at the top, and results dynamically start appearing as you type—whether for suggested Web addresses, search engine results or searches on the current Web page. Just like Safari on a Mac.
Did I Just Install A Battery Gremlin?
Why yes, dear user. Yes, you did. It's not uncommon for major software upgrades to require more power, and there are many well-known battery-saving tactics—from turning off Bluetooth when not in use to dimming your screen brightness.
What's different this time around with iOS 7, however, is the new "App Background Refresh" feature. While it may be convenient for applications to update themselves automatically, it can also be a major battery drain, especially if you have a lot of apps. To shut it off, head into Settings and then General, and toggle Background App Refresh.
These, of course, only scratch the surface. There are many more mysteries surrounding the new iOS, such as:
Why Did Apple Remove The Hidden First Screen?
In iOS 6, users used to swipe from left to right on the first home screen to get a search page. But that's gone now with iOS 7. To search, you pull down from anywhere on the actual homescreen to access a hidden search bar at the top. But don't confuse it with swiping from the very tippy top to access Notifications.
These similar gestures are bound to flummox users and spark accidental triggers. Sure, people will be able to search from any homescreen page they're on, but the irritation of wayward flubs could defeat any convenience this offers.
This leads me to wonder if Apple is saving this first page for something else down the road. But what that could be is anyone's guess. (If you have some theories, let me know in the comments.)
Why Does Swipe-To-Delete Work in The Other Direction Now?
Again, iOS users have been trained for years to swipe left to right to delete. And yet, in apps like Mail and Messages now, we have to retrain our physical memory to go the other way. It's not a major issue, but one of those small irritations that come up multiple times a day. And there doesn't appear to be any reason for it.
Is Apple's Interface Designer Far-Sighted? Or Just Trying To Undermine Jony Ive?
Apple is renowned for its attention to detail and design. And yet, features like Assistive Touch look like a mess. Indeed, there are plenty of inconsistent margins, spacing and other design details across the whole of the operating system, particularly in the placement of text elements. They even sparked a Tumblr blog dedicated to iOS 7's sloppiness.
This is unusual for a company as design-centric as Apple—so much so that one might even wonder if the gaffes were intentional. Is someone in Apple's interface design department out to undermine Apple design chief Jony Ive?
After all, this is the Apple senior vice president's first major release as head of both hardware and software. And while there's no question that he's a genius at industrial design, the aesthetic on the software side is, at best, rough around the edges.
Well, we're not likely to ever know the answer to that one. Meanwhile, as time goes on, we may have plenty of other new iOS 7 weirdness to deal with—like the recently discovered lockscreen bypass bug.
Do you have your own running list of iOS 7 strangeness, bugs or mysteries? If so, share them in the comments below.

porque poesia é importante, porra.
Hoje tive o prazer de ler dois poemas da polonesa Wisława Szymborska, publicados no excelente blog do escritor Carlos Emerson Junior (recomendadíssimo, aí na listinha da direita). Por 12 pequenas coletâneas de poemas, ela já abocanhou um Prêmio Nobel de Literatura, em 1996. Por aí se vê a força de seus textos.
Reproduzo abaixo os dois selecionados por Carlos, para que sempre possamos lê-los também por aqui
Em cada cem pessoas
Aquelas que sempre sabem mais:
cinquenta e duas.
Inseguras de cada passo:
quase todo o resto.
Prontas a ajudar,
desde que não demore muito:
quarenta e nove.
porque não podem ser de outra maneira:
quatro — bem, talvez cinco.
Capazes de admirar sem invejar:
Levadas ao erro
pela juventude (que passa):
sessenta, mais ou menos.
Aquelas com quem é bom não se meter:
quarenta e quatro.
Vivem com medo constante
de alguma coisa ou alguém:
setenta e sete.
Capazes de felicidade:
vinte e alguns, no máximo.
selvagens em multidões:
mais da metade, por certo.
quando forçados pelas circunstâncias:
é melhor não saber
Peritos em prever:
não muitos mais
que os peritos em adivinhar.
Tiram da vida nada além de coisas:
(mas eu gostaria de estar errada).
Dobradas de dor,
sem uma lanterna na escuridão:
oitenta e três,
mais cedo ou mais tarde.
Aqueles que são justos:
uns trinta e cinco.
Mas se for difícil de entender:
Dignos de simpatia:
noventa e nove.
cem em cem –
um número que não tem variado.
à noite arrancou todas as folhas de uma árvore,
para balançar só num galho nu.
Com este exemplo
a Violência demonstra
que sim –
às vezes ela gosta de se divertir.
Essa é e sempre foi uma regra totalmente sem sentido.
Alguém já assistiu?
Tem muita mulher que detesta filme pornô. Não suporta tantos gemidos falsos, os roteiros mais do que previsíveis, seguindo a velha sequência vaginal-anal-gozada-na-cara, os closes exagerados de buracos que nem imaginávamos tão elásticos, além do machismo onipresente, que transforma as mulheres em meros objetos de prazer, sempre prontas a satisfazer todos os desejos masculinos. A predominância de filmes feito por homens para homens no mercado erótico traumatizou um pouco a mulherada e também provocou o desinteresse delas por esse tipo de produto. Mas existe uma luz (ou uma trepada diferente) no fim do túnel. Várias cineastas mulheres estão quebrando o monopólio masculino da indústria pornô. Erika Lust é uma dessas desbravadoras, que trabalham para fazer as mulheres também gozarem com os olhos.
A cineasta sueca não faz o tipo depravada, muito menos boca do lixo. Erika Lust é formada em Ciência Política, com especialização em estudos de gênero e direitos humanos. A vontade de dar voz às mulheres em uma indústria até então tipicamente machista foi o que motivou Erika a escrever, produzir e dirigir filmes pornôs. Fez seu primeiro curta em 2004 e debutou com o longa Five Hot Stories for Her em 2007. Seus filmes seguem a linha que se tornou conhecida como female friendly, ou seja, em que a mulher não é subjugada e as atrizes seguem padrões estéticos mais próximos à realidade. A diretora também não costuma incluir em seus roteiros sexo anal ou gozo na cara, para fugir do “status quo” da pornografia masculina.
Para quem nunca assistiu a nenhum filme de Erika Lust ou de outra cineasta pornô feminista, vou tentar descrever a experiência. Esses filmes possuem uma carga erótica mais intensa e geralmente o prazer feminino é o principal protagonista. As produções de Erika têm boa qualidade técnica, os filmes são mais ricos na história e buscam estimular todos os sentidos, caprichando mais no figurino, cenário, na iluminação, música, dando ênfase aos detalhes. O sexo aparece explícito, porém sem closes exagerados. Os corpos das atrizes representam bem a realidade. Muitas delas têm pneuzinhos, estrias, celulites e até espinhas na bunda. Não se esconde nada e os corpos se movimentam com mais naturalidade na tela, sem aquela preocupação excessiva com o melhor ângulo.
Cabaret Desire, o mais recente lançamento da cineasta sueca que mora em Barcelona, ganhou vários prêmios, inclusive de filme do ano de 2012 no Feminist Porn Awards. O filme narra diferentes histórias eróticas, que começam sendo contadas no ambiente de um cabaré. A primeira delas é sobre a dona de um bar que se envolve simultaneamente com um homem e uma mulher. As cenas de sexo entre mulheres são frequentes nas produções de Erika Lust, ao que tudo indica essa também é uma fantasia feminina, entretanto elas não acontecem como mais uma forma de deleite masculino. O prazer entre elas fica somente entre elas. Alternando o sexo com o rapaz e a moça, a cineasta consegue criar um paralelo interessante de força e suavidade.
O sexo oral feminino aparece com tanta frequência nos pornôs para mulheres quanto o boquete nas produções voltadas para homens. O mais gostoso de assistir a esses filmes é ser colocada em primeiro plano, tudo o que acontece tem como objetivo principal satisfazer a mulher. Mesmo as cenas de submissão têm essa finalidade. Esses filmes se desenrolam em um ritmo mais lento, com a intenção de criar um clima e ir despertando os sentidos aos poucos, o que costuma agradar as mulheres. Mas não sei se os homens conseguem assistir até o final, ainda mais sabendo que não haverá aquela gozada clássica na cara.
Desconto – não é jabá
Erika Lust mantém o portal Lust Cinema, com suas produções e outros filmes pornôs alternativos. Para assistir aos filmes online e por download, é preciso fazer uma assinatura mensal, trimestral ou anual. Entrei em contato com a produção da Lust Cinema e pedi um desconto para as leitoras e leitores do Para Pensar em Sexo. Eles me enviaram um código (voucher) que dá direito a 50% de desconto em qualquer assinatura. O valor de uma assinatura mensal é de $ 34,95 dólares, mas com o voucher sai por $ 17,47 dólares. Isso não é jabá, não tenho nenhuma parceria com a Erika Lust, nem recebi nada por esse post, inclusive paguei minha assinatura para poder assistir aos filmes e escrever esse texto. Para receber o voucher, mande e-mail no firstname.lastname@example.org solicitando o desconto, que responderei enviando o código.

I swear, my wife was slain by a one-armed robot!!!
Your personal robot butler just got a lot more affordable—and a lot easier to hack, too. Meet UBR-1, a one-armed orange humanoid that'll fit right in at your robotics research laboratory, or perhaps even your business. For the low, low price of just $35,000.
Equipped with a visual interface called MoveIt! for directing its motions, UBR-1 might just be the most sophisticated robot that even a human with relatively little robotics training can operate. MoveIt! is an app with a drag-and-drop interface that interacts with a robot's sensors. Using that sensor data, MoveIt! gives the user a 3D model of the robot in its actual physical environment, so the user can test out and direct a robot's movements virtually before making them happen in real time.
UBR-1 is the first robot offering from Unbounded Robotics, the latest and final spin-off from late, great Palo Alto, Calif., robotics studio Willow Garage. Willow Garage, which invented MoveIt! earlier this year, was best known for a larger, pricier two-armed humanoid, the PR2. But if the highly acclaimed PR2 is the shiny gold iPhone of robotics, UBR-1 is the iPhone 5C: all the same functionality in a bright plastic case, with a lower price tag.
Unbounded Robotics' founding members with UBR-1.
In Unbounded Robotics’ first official blog post, it acknowledges that comparisons to the pricier model are inevitable, especially since all four founding members (Eric Diehr, Michael Ferguson, Derek King, and Melonee Wise) are Willow Garage alums. But that's a good thing, the company insists:
While the UBR-1 is not specifically designed as the heir apparent for the PR2, we take pride in the comparison. The UBR-1 offers a far more sophisticated platform than the PR2, however, which was originally designed more than five years ago... [T]he UBR-1 is also approximately one-tenth the cost of the PR2.
What makes it so much cheaper while still improving on the technology? Look no further than UBR-1's solitary arm. And, as an additional perk for robotics enthusiasts, a one armed robot is far easier to program than a dual-armed one.
The 160-pound, 4-foot-3 robot can perform simple human tasks like picking up and delivering objects—especially, as Unbounded notes, in automated business situations. Since it doesn’t require calibration and it’s already equipped with MoveIt!, it’s ready to get started almost right out of the box. Of course, UBR-1 is at its heart a research robot, and runs ROS (the open-source Robot Operating System) and Ubuntu Linux LTS so it can support whatever complicated applications roboticists can think up.
Interested robotics researchers and businesses can pre-order UBR-1 “soon” and will receive the first models in summer 2014.

Why Finnish babies sleep in cardboard boxes
For 75 years, Finland’s expectant mothers have been given a box by the state. It’s like a starter kit of clothes, sheets and toys that can even be used as a bed. And some say it helped Finland achieve one of the world’s lowest infant mortality rates.
It’s a tradition that dates back to the 1930s and it’s designed to give all children in Finland, no matter what background they’re from, an equal start in life.
The maternity package - a gift from the government - is available to all expectant mothers.
It contains bodysuits, a sleeping bag, outdoor gear, bathing products for the baby, as well as nappies, bedding and a small mattress.
With the mattress in the bottom, the box becomes a baby’s first bed. Many children, from all social backgrounds, have their first naps within the safety of the box’s four cardboard walls.
Mothers have a choice between taking the box, or a cash grant, currently set at 140 euros, but 95% opt for the box as it’s worth much more.
The tradition dates back to 1938. To begin with, the scheme was only available to families on low incomes, but that changed in 1949.
Socialism at work.
I would rather my tax money pay for this than drone missiles.

“It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters.” -Friedrich Nietzsche
Although the innermost planets, from Mercury through Saturn, were known since ancient times, it’s only since the advent of the telescope that we’ve discovered what really lives in our Solar System. Over the past four centuries, the wonders of not only the distant Universe, but also our nearby neighborhood, have been uncovered in spectacular detail.
The third and fourth largest planets were discovered, as were a plethora of moons around other worlds, a belt of asteroids between Mars and Jupiter (at the ice-line of our Solar System, or where the strength of the Sun is insufficient to move water out of its solid phase), and a Kuiper belt out beyond the final planet. (And the Oort cloud even beyond that!)
Although Uranus was discovered in 1781 by William Herschel and its bizarre failure to adhere to Kepler’s laws led to the prediction-and-discovery of Neptune in 1846, it wasn’t until 1930 that a lone astronomer, looking at pairs of images taken at different times, happened upon the serendipitous discovery of a lifetime.
Even though it was the only world located out beyond the orbit of Neptune for nearly 50 years (until Pluto’s largest moon, Charon, was discovered), it was recognized relatively quickly that Pluto was a harbinger for many more such objects, now recognized (and confirmed, since 1992) to be just one of a great many located in the Kuiper Belt. The other bodies began to exhibit a variety of sizes, shapes, and orbital characteristics, although they all had a number of properties that threw Pluto’s “privileged” status as a “planet” into question:
This all came to a head in 2005, when it was discovered that Pluto isn’t even the most massive object in the Kuiper Belt!
That distinction belongs to Eris, which weighs in at about 127% the mass of Pluto. That discovery paved the way for a new classification scheme that included an additional class of Solar System objects known as dwarf planets, of which Eris and Pluto are the two most massive at the present time.
But when it comes to the King of all Kuiper Belt objects, none of these little monsters can stake that claim. Because there’s one object that we don’t normally think of as a Kuiper Belt object that has them all beat.
This is Neptune, the outermost planet in our Solar System. No, it doesn’t qualify as a Kuiper Belt object; it’s a planet, just like you’ve always learned. But back in 1846, there were some awfully powerful telescopes in the world, certainly much better and bigger ones than were around in 1781 (when Uranus was discovered) or at any time before that. Back in 1781, there was only one telescope in the world — commissioned in 1780 — that had a primary mirror of two feet (61 cm) or more in diameter.
By time 1846 came around, the largest telescope in the world had a primary mirror that was six feet (1.8 meters) in diameter, and amateurs with no formal training — like William Lassell — were building their own two foot diameter telescopes themselves.
The timetable for the discovery of Neptune was swift: Urbain Le Verrier announced his prediction for the undiscovered planet’s position on August 31, 1846, and composed a letter to Johann Galle, director of the Berlin observatory. Galle and his assistant, Heinrich d’Arrest, looked for the planet on September 23, and discovered it that very night in one of the greatest accomplishments of all-time in theoretical astrophysics.
But news traveled fast, and back in England, William Lassell was eager to view the newly-discovered world.
Just 17 days after the discovery of the hypothesized new world that had occupied many of the world’s greatest professional astronomers for decades, a virtually unknown and amateur telescope-maker discovered Triton, by far the largest satellite world of Neptune. (Although to be fair, it was the largest telescope in England at the time.) If all the Solar System’s moons were compared to one another, Triton would be the seventh largest in size, behind only Earth’s Moon, Saturn’s Titan, and the four Jovian moons discovered by Galileo.
But — up close — Triton doesn’t look like any other large moon in the entire Solar System! For one, every other large moon revolves around its planet the same way all the planets revolve around the Sun: counterclockwise, as viewed if you flew directly upwards above the Earth’s north pole. But not Triton, which revolves around Neptune in the opposite direction!
In terms of density, it resembles Pluto far more than it resembles either Neptune or any other Moon in the Solar System. And in terms of atmospheric composition, it’s virtually identical to the known worlds found in the Kuiper Belt.
What does all this mean?
That Triton isn’t a naturally occurring moon of Neptune, but has been gravitationally captured (by the same mechanism described here last week) from its place of origin: the Kuiper Belt. Even though it isn’t currently in the Kuiper Belt, that doesn’t stop it from being the largest, most massive, most accessible, first-discovered, and in many subjective ways, greatest Kuiper Belt Object of them all!
But it’s real, it’s spectacular, and unlike every other Kuiper Belt Object (so far), we’ve been there! That was thanks to Voyager 2 in 1989; take a look at this photo mosaic of a large chunk of its surface!
If it looks cantaloupe-like to you away from the poles, well done; that’s the semi-official NASA term for it! So the next time you think about worlds from beyond our planets, don’t just think of frozen ice-and-rock-balls orbiting in deep space, nor only of the comets disturbed by passing gravitational bodies and hurled inwards towards the Sun, but also of the rogue worlds that migrate inwards and wind up captured by gas giants.
After all, if you didn’t include them, you’d be missing out on Triton, largest of all the trans-Neptunian objects and the onetime King of the Kuiper Belt!
Exatamente como eu seria se morasse no Zuza por esses dias. O bicho tá pegando por lá mesmo.
Marina "espalha-bolinho" Silva.
Não tem isso de discutir lá na frente posição na chapa. A candidatura posta é a de Eduardo e ela vai até o dia da eleição. A cabeça de chapa se chama Eduardo Henrique Accioly Campos e esse será o nome na urna no dia da eleiçãoE, assim, vai se repetindo a história de Marina.
Legais as perguntas, Igor.
Quem me lê há anos talvez não lembre que às vezes eu uso o 42. como um mecanismo de busca orgânico (faz um tempinho que não pergunto nada aqui, maldito seja o Facebook) e a pergunta a seguir está me corroendo desde que aprendi a usar tal utensílio culinário.
A pressão criada numa panela de pressão atua diretamente no alimento?
Se você lembra desse jogo, sua infância foi há muuuuuito tempo.
Explico: eu notei que cozinhar batatas na pressão faz com que elas fiquem consideravelmente mais firmes do que aquelas cozidas ao ar livre. Desde que eu deixe a panela esfriar e perder pressão ao seu próprio ritmo. Se levantar o pitoquinho (ou “válvula de escape”, para os não-potiguares) fazendo a pressão residual cair rapidamente, os tubérculos estouram como uma espinha inflamada antes de um encontro romântico.
É notável também que carnes cozinham até o ponto em que se desmancham como algodão doce em boca de cachorro mas continuam a manter o formato (novamente, desde que a pressão se equilibre com a ambiente naturalmente).
Eu entendo que, ao ferver sob pressão, a água muda de estado mais calmamente e não forma bolhas tão violentas (um alô para os laboratoristas!), mas a manutenção do formato da carne e da consistência das batatas se dá só por isso? Ou a pressão em si influencia o resultado, segurando as fibras/amido no formato/consistência original?
Minha dúvida é a seguinte: já que geralmente essas coisas estão submersas num líquido não-comprimível, a pressão tem influencia direta sobre as comidas ou apenas o aumento da temperatura explica os fenômenos descritos?
A grande maioria dos hacks funcionou, ao contrário do que aparenta...
Life Hacks? More like Lie Hacks.
In the latest episode of Mental Floss, “30 Life Hacks Debunked,” host John Green tests out common Life Hacks to find out which ones work and which ones don’t. For instance, Green discovers that chewing gum to prevent crying while chopping an onion does actually work, but he couldn’t open a bottle of wine using only a hammer and a nail.
Passengers on San Francisco's Muni train were so focused on their smartphones that they didn't notice a man drawing and pointing his gun until he shot university student Justin Valdez, District Attorney George Gascón says. As SFGate reports, security footage from September 23rd captured "dozens" of passengers apparently ignoring a man who drew a .45-caliber pistol several times, pointed it across the aisle, and eventually shot Valdez as he stepped off the train. "These weren't concealed movements — the gun is very clear," Gascón told SFGate. "These people are in very close proximity with him, and nobody sees this. They're just so engrossed, texting and reading and whatnot. They're completely oblivious of their surroundings."
The shooter was allegedly Nikhom Thephakaysone, who has since been arrested. But Gascón said that although cellphones help people document and report crimes, they created a kind of bystander apathy in this case. It's not clear how full the train was, although dozens of people would add up to a crowded car. Multiple reports have cited "distracted walking" — while using a smartphone or other device — as a cause of increased accidents, just as cell use while driving has been deemed a potentially fatal risk. On subways, though, other factors could also make people less likely to spot warning signs. Phones aren't inherently more distracting than books or newspapers, and looking too closely at passengers on a crowded train is often considered taboo — in this case, it's also not clear how much it would have helped. As the video hasn't been released, we're left only with Gascón's warning that a busy screen can add up to a deadly distraction.
Eu já sabia... mas fica a dica.
Writing at The Guardian, Bruce Schneier explains in his latest Edward Snowden–related piece that the US National Security Agency (NSA) had tried unsuccessfully to mount an attack against the Tor network, in hopes of bypassing the service's anonymity protections. Nevertheless, the NSA is still able to identify Tor traffic and track individual Tor users (despite not knowing their identities), which can lead to further surveillance. "After identifying an individual Tor user on the internet, the NSA uses its network of secret internet servers to redirect those users to another set of secret internet servers, with the codename FoxAcid, to infect the user's computer. FoxAcid is an NSA system designed to act as a matchmaker between potential targets and attacks developed by the NSA, giving the agency opportunity to launch prepared attacks against their systems." By targeting a Tor user, the agency could then leverage attacks like browser exploits to get into the user's system; nevertheless, so far the design of Tor itself seems to be functioning as planned.
