Oculus Rift Guillotine Simulation

Posted by on May 7, 2013 No comments

An anonymous reader tipped us to news of an interesting hack for the Oculus Rift: a simulation of being beheaded by a Guillotine. Thrown together in a couple of days at the Exile Code Jam, the simulation lets you… “look around to see the blade above, the crowd of onlookers around them, and the executioner who signals the blade be dropped. It also enhances the experience when someone watches the blade falling on a nearby screen and taps the user on the back of the neck at the time of impact.” Just a bit morbid. There’s a video of people “playing” (nsfw language in a few reactions to being virtually beheaded).

RPI Supercomputer Smashes Simulation Speed Record

Posted by on May 2, 2013 No comments

Lank writes “A team of computer scientists from Lawrence Livermore National Laboratory and Rensselaer Polytechnic Institute have managed to coordinate nearly 2 million cores to achieve a blistering 504 billion events per second, over 40 times faster than the previous record. This result was achieved on Sequoia, a 120-rack IBM Blue Gene/Q normally used to run classified nuclear simulations. Note: I am a co-author of the coming paper to appear in PADS 2013.”

Best of 2012: The Measurement That Would Reveal The Universe As A Computer Simulation

Alt-week 10.13.12: is the Universe a simulation, cloning dinosaurs and singing mice

Posted by on October 13, 2012 No comments

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Altweek 101312 is the Universe a simulation, cloning dinosaurs and singing mice

Are you reading this? Seriously, are you? Sure, we know you think you are, but what if you’re just a sub-feature of a complex computer program. A sprite, nothing more than the creation of software. The problem with this question is, how would you ever know? You wouldn’t, right? Well, not so fast there. Turns out, maybe there is a way to unravel the matrix (if there is one). It’ll come as no surprise, that this is one of the topics in this week’s collection of alternative stories. Think that’s all we got? Not even close. We’ll explore the truth behind cloning dinosaurs, as well a rare performance by singing mice — all before dinner. Or is it really dinner? This is alt-week.

The Measurement That Would Reveal The Universe As A Computer Simulation

Posted by on October 10, 2012 No comments

If the cosmos is a numerical simulation, there ought to be clues in the spectrum of high energy cosmic rays, say theorists

One of modern physics’ most cherished ideas is quantum chromodynamics, the theory that describes the strong nuclear force, how it binds quarks and gluons into protons and neutrons, how these form nuclei that themselves interact. This is the universe at its most fundamental.

A $1.2bn Simulation of Civilization

Posted by on August 16, 2012 No comments

An ambitious European project wants to build super-real simulations to help predict the future.

Ever wish you could turn back the clock and try a day, week, or year over again? Plans afoot in Switzerland to build a more detailed simulation of the globe’s environment, societies, and economies than ever before could make that possible. Professor Dirk Helbing of the Swiss Federal Institute of Technology Zurich wants to build a “living earth simulator” to probe the kind of dangerous cascading effects that he believes threaten financial markets, power grids and other complex systems that modern life relies upon. He has a good chance at getting €1bn ($ 1.2bn) of EU research funding to build it, as co-leader of one of six projects competing for two huge research grants.

First Simulation Of Quantum Tunnelling On A Quantum Computer

Posted by on May 15, 2012 No comments

Quantum tunnelling had always been thought too complex to simulate on today’s simple quantum computers. Now a new approach to quantum computing has changed that and opens the door to more complex simulations

The exploitation of quantum weirdness for computing is one of the great goals of modern physics. It’s promise is dramatic for a wide range of number-crunching tasks.

Antimatter Propulsion Engine Redesigned Using CERN’s Particle Physics Simulation Toolkit

Posted by on May 14, 2012 No comments

Latest simulation shows that the magnetic nozzles required for antimatter propulsion could be vastly more efficient than previously thought–and built with today’s technologies

Smash a lump of matter into antimatter and it will release a thousand times more energy than the same mass of fuel in a nuclear fission reactor and some 2 billion times more than burning the equivalent in hydrocarbons.

First Full Observable-Universe Simulation

Posted by on April 22, 2012 No comments



First time accepted submitter slashmatteo writes “The goal of the DEUS project (Dark Energy Universe Simulation) is to investigate the imprints of dark energy on cosmic structure formation through high-performance numerical simulations. In order to do so, the project has conducted a simulation of the structuring of the entire observable universe, from the Big Bang to the present day. Thanks to the Curie super-computer, the simulation has made it possible to follow the evolution of 550 billion particles. Two other complementary runs are scheduled by the end of May. More details in the press release.”

Computer Simulation Predicts New Allotrope Of Carbon

Posted by on February 29, 2012 No comments

The new material matches the properties of a puzzling new form of carbon found in high pressure experiments

The various different forms of carbon include diamond, graphite, graphene (a single sheet of graphite) and the fullerenes, which form when carbon atoms bond together into tube and sphere-like structures.

Blog – First Simulation Of The Supernova That Fathered Our Solar System

Posted by on November 3, 2011 No comments

Computer model confirms that our Solar System was born from the ashes a dead star

The origin of the Solar System is one of the fundamental problems in astrophysics. The general mechanism is well understood–a giant cloud of gas and dust must have collapsed to form the Sun and planets–but the devil is the detail. For example, what could have triggered such a collapse?
