The Illustris Project is Simulated Beauty

The Illustris Project just released their preliminary results, and it’s nothing short of incredible. Although their simulation is massively complex, I particularly love checking out the fantastic graphics they’re able to generate from the data, available on their media page. Explore the Illustris Simulation Data More on Illustris: Motivation & Big Ideas The standard model of cosmology posits that the mass-energy density of the Universe is dominated by unknown forms of dark matter and dark energy. Testing this extraordinary scenario requires precise predictions for the formation of structure in the visible matter, which is directly observable as stars, diffuse gas, and accreting black holes. These components of the visible matter are organized in a ‘Cosmic Web’ of sheets, filaments, and voids, inside which the basic units of cosmic structure – galaxies – are embedded. To test our current ideas on the formation and evolution of galaxies, we strive to create simulated galaxies as detailed and realistic as possible, and compare them to galaxies observed in the real universe. By probing our successes and failures, we can further enhance our understanding of the galaxy formation process, and thereby perhaps realize something fundamental about the world in which we live. The Illustris project is a set of large-scale cosmological simulations, including the most ambitious simulation of galaxy formation yet performed. The calculation tracks the expansion of the universe, the gravitational pull of matter onto itself, the motion or “hydrodynamics” of cosmic gas, as well as the formation of stars and black holes. These physical components and processes are all modeled starting from initial conditions resembling the very young universe 300,000 years after the Big Bang and until the present day, spanning over 13.8 billion years of cosmic evolution. The simulated volume contains tens of thousands of galaxies captured in high-detail, covering a …

Crazy structures for the UIAA Ice Climbing World Cup, including all sorts of overhanging, free floating barrels, and convoluted shapes. We got to see a few of these recently in Ouray, Colorado. Via Gizmodo: Ice-Climbing Structures Are Mind-Blowing Experimental Architecture

The Coldest Place in the World: Dome Argus, East Antarctica

Jeffrey Donenfeld News, Science, Video Leave a Comment

NASA recently revealed that a spot in Antarctica just hit a record -135.3 degrees F below zero – that’s cold! In my time at the south pole, the coldest I experienced was -60F – not even close to the record. Fron NBC News: Ice scientist Ted Scambos at the National Snow and Ice Data Center said the new record is “50 degrees colder than anything that has ever been seen in Alaska or Siberia or certainly North Dakota.” “It’s more like you’d see on Mars on a nice summer day in the poles,” Scambos said, from the American Geophysical Union scientific meeting in San Francisco Monday, where he announced the data. “I’m confident that these pockets are the coldest places on Earth.” Here’s a quick explainer video.

When Bitcoin starts being accepted at major real world brick and mortar stores, how are you going to ensure that your Bitcoins stay safe? Bitcoin is not like a physical currency – it exists only in the digital world, and your ownership of your digital store of Bitcoins is dependent on you keeping, and keeping secure your private keys to your walled. As Bitcoins become more mainstream, security will become more and more critical for this digital currency. To help lock it all down, new startup Trezor is making a physical Bitcoin security computer, shaped like a key fob. Here’s the details: TREZOR The Bitcoin Safe.

A Tour of the Amundsen-Scott South Pole Station, Antarctica

After living and working at the Amundsen-Scott South Pole Station during the summer 2012-2013 season, I’ve had the chance to see most parts of the station. Additionally, I also worked as a tour guide for the various tourist groups who visited the station. Here’s a brief narrated video tour of both the elevated station as well as the buried service structures. Shot on the Sony RX100. For more on my time in Antarctica, be sure to see my Antartica Blog.
