by wagatwe










ricktimus:

Neil deGrasse Tyson is not impressed with all your sexism.

Edit: This post made it to the Science tag! As a science aficionado, this of course makes me happy.

So lots of people have reblogged pointing out the irony that I didn’t even include the names of the scientists in my original post. This is mostly true. I did include their names on my post, but that was only in the tag section, and even then it was for my own reference purposes. Had I known this was going to be reblogged like mad and added to an educational category I, would have at least included links to their respective biographies and stuff, instead of only just my glib commentary.*

But that is what the edit feature is for, I suppose. SO HERE ARE SOME LINKS:

AND ALSO:

* Not that I will ever regret writing glib commentary about Neil deGrasse Tyson throwing some serious shade at the past.

Momentum is a project by artist Alejandro Guijarro who spent three years traveling to the quantum mechanics departments of Cambridge, Stanford, Berkeley, Oxford and elsewhere to shoot large format photographs of blackboards just after lectures. Completely removed from the context of a classroom or laboratory and displayed in a gallery, the cryptic equations from one of the most formidable branches of physics become abstract patterns of line and color. Via the artist’s statement:

Before he walks into a lecture hall Guijarro has no idea what he will find. He begins by recording the blackboard with the minimum of interference. No detail of the lecture hall is included, the blackboard frame is removed and we are left with a surface charged with abstract equations. At this stage they are documents. However, once removed from their institutional beginnings the meaning evolves. The viewer begins to appreciate the equations for their line and form. Colour comes into play and the waves created by the blackboard eraser suggest a vast landscape or galactic setting. The formulas appear to illustrate the worlds of Quantum Mechanics. What began as a precise lecture, a description of the physicist’s thought process, is transformed into a canvas open to any number of possibilities.

Guijarro graduated from the Royal College of Art in 2010 with a MA in fine art and now lives
and works in both London and Madrid. He’ll have work later this year at PhotoEspaña. (via Not Shaking the Grass)

Water Droplets Flow Uphill through a Superheated Maze Thanks to the Leidenfrost Effect water science mazes

The folks over at Science Friday made this fascinating video about the Leidenfrost Effect, where water dropped on an extremely hot surface is capable of floating instead of immediately evaporating. While studying the bizarre effect, physicists at the University of Bath realized that not only does the water float, but under the right conditions and temperatures it can actually climb upward. The playful experiments lead to the creation of an incredible superheated maze. (via The Awesomer)

Too long; didn’t read pour vos man pages

by Korben
Giseli.ramos

Opa, vou testar aqui, porque realmente fico com preguiça de ler o man de alguns comandos...

tldr est une application (un module npm plus exactement) qui permet d'obtenir des infos de type "man" sur une commande, mais uniquement des exemples clair et utiles dans la vie de tous les jours, sans tout le blabla technique (qui a aussi son utilité dans d'autres cas évidemment). C'est du spécial n00b pressé et c'est top !

Par exemple, si de manière classique vous faites un "man tar", vous obtenez ceci :

mantar Too long; didnt read pour vos man pages

Mais si vous utilisez à la place un "tldr tar", vous obtiendrez ceci :

screenshot11 Too long; didnt read pour vos man pages

Pour info, tldr est une abréviation connue d'Internet qui signifie "Too long; didn't read", soit "Trop long; pas lu".

Pour l'installer, vous devez avoir npm (Node Packaged Modules) et lancer la commande suivante :

npm install -g tldr

Cet article merveilleux et sans aucun égal intitulé : Too long; didn’t read pour vos man pages ; a été publié sur Korben, le seul site qui t'aime plus fort que tes parents.

Mathematician: Is Our Universe a Simulation?

by samzenpus
Giseli.ramos

Vez ou outra penso nessa possibilidade. De qualquer modo, espero que tenha experimentos que possam refutar ou provar isso, seria interessante!

Hugh Pickens DOT Com writes "Mathematician Edward Frenkel writes in the NYT that one fanciful possibility that explains why mathematics seems to permeate our universe is that we live in a computer simulation based on the laws of mathematics — not in what we commonly take to be the real world. According to this theory, some highly advanced computer programmer of the future has devised this simulation, and we are unknowingly part of it. Thus when we discover a mathematical truth, we are simply discovering aspects of the code that the programmer used. This may strike you as very unlikely writes Frenkel but physicists have been creating their own computer simulations of the forces of nature for years — on a tiny scale, the size of an atomic nucleus. They use a three-dimensional grid to model a little chunk of the universe; then they run the program to see what happens. 'Oxford philosopher Nick Bostrom has argued that we are more likely to be in such a simulation than not,' writes Frenkel. 'If such simulations are possible in theory, he reasons, then eventually humans will create them — presumably many of them. If this is so, in time there will be many more simulated worlds than nonsimulated ones. Statistically speaking, therefore, we are more likely to be living in a simulated world than the real one.' The question now becomes is there any way to empirically test this hypothesis and the answer surprisingly is yes. In a recent paper, 'Constraints on the Universe as a Numerical Simulation,' the physicists Silas R. Beane, Zohreh Davoudi and Martin J. Savage outline a possible method for detecting that our world is actually a computer simulation (PDF). Savage and his colleagues assume that any future simulators would use some of the same techniques current scientists use to run simulations, with the same constraints. The future simulators, Savage indicated, would map their universe on a mathematical lattice or grid, consisting of points and lines. But computer simulations generate slight but distinctive anomalies — certain kinds of asymmetries and they suggest that a closer look at cosmic rays may reveal similar asymmetries. If so, this would indicate that we might — just might — ourselves be in someone else's computer simulation."

it8bit:

MODERN DAY CLASSICS GONE CLASSIC

OTLgamingDeviantART user Bunnelle has a vision for the future of gaming that doesn’t include HD graphics and surround sound, but instead features a bountiful harvest of 8bit goodness.

Or, she simply had the idea of taking modern day games and re-envisioning them in the style of classic Atari cartridge art. It’s definitely one of the two.

142. TIMOTHY FERRISS: Someday

by Gav

142. TIMOTHY FERRISS: Someday

Timothy Ferriss is an author, entrepreneur, blogger and television host. He’s best known as the 4-Hour guru who helped pioneer the ‘lifestyle design’ movement. This quote is taken from Ferriss’ first book, The 4-Hour Workweek, which I read when I was in the middle of my career change and helped motivate me to eventually start this website. The book teaches people to rethink the outdated idea of working a 9-5 job and to use today’s technology to find the perfect work/life balance.

Ferriss recently debuted his new TV show, The Tim Ferriss Experiment, where he applies his life-hacking rules to a number of different disciplines.

I was fortunate enough to meet Tim and contribute some illustrations to his latest book, The 4-Hour Chef. Here’s a blog post I wrote about it with some behind-the-scenes sketches.

Kazakh Professor Claims Solution of Another Millennium Prize Problem

by Soulskill
Giseli.ramos

Tô curiosa se isso vai se sustentar ou não...

An anonymous reader writes "Kazakh news site BNews.kz reports that Mukhtarbay Otelbaev, Director of the Eurasian Mathematical Institute of the Eurasian National University, is claiming to have found the solution to another Millennium Prize Problems. His paper, which is called 'Existence of a strong solution of the Navier-Stokes equations' and is freely available online (PDF in Russian), may present a solution to the fundamental partial differentials equations that describe the flow of incompressible fluids for which, until now, only a subset of specific solutions have been found. So far, only one of the seven Millennium problems was solved — the Poincaré conjecture, by Grigori Perelman in 2003. If Otelbaev's solution is confirmed, not only it might be the first time that the $1 million offered by the Clay Millennium Prize will find a home (Perelman refused the prize in 2010), but also engineering libraries will soon have to update their Fluid Mechanic books."

Just a cursory glance at a few storm photos by Mike Hollingshead and it’s clear this guy has probably seen it all, and probably put his life at risk to do so. The intrepid storm chaser has been enduring foul weather since the late 90s, clocking some 20,000 miles a year in his car as he stalks thunderstorms and other extreme weather occurrences waiting to capture the perfect shot. Hollingshead shares his story with Jakob Schiller over at Raw File, and you can see hundreds of his photos, many available for purchase as prints, over on his website. All images courtesy the artist.

Did a bunch of dogs breakup a fight between two cats? Am I seeing this right??

Having none of that shit today.

“Ay man, y’all chill the fuck out. Y’all fucking up the party.”

I CAN’T BELIEVE WHAT I’M SEEING

Pack animals like dogs don’t tolerate dissent in their group because it weakens the pack’s social structure… There are similar clips on youtube of them breaking up rabbit and rooster fights… They don’t care what species you are, they just want you to CUT THAT SHIT OUT.

They don’t differentiate species because dogs think everything else is just a weird dog.
