    (CNSNews.com) – The National Science Foundation has awarded a $356,337 grant to the University of Iowa to use virtual technology to study social influences on risky cycling and pedestrian behavior. “This project will create a simulation facility that will advance a capability to study the social interactions of two children, or a child and parent, as the two people walk or bicycle across a traffic-filled roadway,” the grant announcement said. It will “expand existing infrastructure” at the university “to build a new simulator that matches a recently installed simulator at the same institution, which will permit each of two experimental...
  • Do we live in a computer simulation? How to test the idea.

    The concept that we could possibly be living in a computer simulation comes from a 2003 paper published in Philosophical Quarterly by Nick Bostrom, a philosophy professor at the University of Oxford. With current limitations and trends in computing, it will be decades before researchers will be able to run even primitive simulations of the universe. But a University of Washington team has suggested tests that can be performed now, or in the near future, that could resolve the question. Currently, supercomputers using a technique called lattice quantum chromodynamics (LQC), and starting from the fundamental physical laws that govern the universe, can...

    A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. While that seems far-fetched, perhaps even incomprehensible, a team of physicists at the University of Washington has come up with a potential test to see if the idea holds water. The concept that current humanity could possibly be living in a computer simulation comes from a 2003 paper published in Philosophical Quarterly by Nick Bostrom, a philosophy professor at the University of Oxford. In the paper, he argued that at least one of...

    A U.S. supercomputer has won back the crown in the never-ending battle for the world's most powerful supercomputer. Its victory is the latest milestone marking the steady climb of computing power all across the globe. The Top500 industry list gave its No. 1 ranking to the Sequoia supercomputer housed at Lawrence Livermore National Laboratory in California — a spot earned by Sequoia's ability to crunch 16.32 quadrillion calculations per second (16.32 petaflops/s). Such supercomputing power is used by the U.S. National Nuclear Security Administration to simulate nuclear weapons tests for older weapons that have been sitting in the U.S. arsenal....

    The Australian Parliament’s Joint Committee on Foreign Affairs, Defence and Trade has just released a transcript of a Feb. 7, 2012 hearing during which it took evidence on the F-35 program by noted opponents of the program, representing the Air Power Australia think-tank and a private computer simulation firm, RepSim Pty Ltd. Part of the hearing describes the outcome of a famous – but disputed – simulation of F-18E and F-35 fighters engaging in combat against Chinese air force fighters carried out by the Rand Corporation. The outcome is even more disastrous for the Western fighters than previously reported. http://www.defense-aerospace.com/articles-view/verbatim/4/133273/f_35-fares-worse-in-rand-wargame.html

    For those that were wondering how my predicted simulation worked out, it was okay if you switched Gingrich and Santorum's numbers for the most part, moved Bachmann to where Santorum was and bump Paul up more. I've done some analysis on the results. I was in the process of doing a county-by-county note update, but after 30 counties of 99, it's taking too damn long. So I'll just get to the basics: As for accuracy, it seems I know the people of Davis County like Rush knows his glorious naked body /sarc. It was my most accurate projection county-wise though...

    I've put up a free economic simulation engine online that lets you analyze and compare the effects of various economic changes against a baseline. The idea is to attempt to illustrate how macro economic changes actually effect people. Raise and lower taxes, fuel prices, introduce real estate and food pricing bubbles, sin taxes, carbon taxes, and more, and see how the effects of these all play out against various demographics of low, medium and high income. You can see how much less or more cash at the end of five years each demographic has to spend, how many more payments,...

    U.S. scientists say they have created an automated program designed to "debug" the nation's nuclear test computer simulations. Purdue University researchers, working with scientists at the Lawrence Livermore National Laboratory, said their program, called AutomaDeD (pronounced like automated), finds errors in computer code for complex "parallel" programs. Because international treaties forbid the detonation of nuclear test weapons, certification is done using complex simulations. The researchers said such simulations, which may contain as many as 100,000 lines of computer code, must accurately show reactions taking place on the scale of milliseconds, or thousandths of a second. "The simulations take several weeks...

    The U.S. Strategic Command last year held one of its largest major exercises simulating a nuclear attack on the United States and a counterstrike involving bombers, ground-based missiles and submarine-launched missiles. Air Force Gen. Kevin Chilton last week told the House Armed Services subcommittee that the exercise was “the most extensive nuclear command, control and communications field exercise in over a decade.” “It demonstrated the full range of nuclear deterrence capabilities by integrating submarine strategic deterrent patrols, more than 90 aircraft sorties, an ICBM test launch, and five days of continuous airborne command-and-control operations,” he said.

    Manned aircraft will be able to penetrate future advanced defenses. Now somebody tell the simulation gang. Historically, there has been a mismatch between the air combat attrition predictions of analysts’ computer models and the actual attrition experienced in major air campaigns. Simply put, the models have always erred on the pessimistic side. Understanding the sources of this mismatch is important today because many Air Force and Pentagon experts are at it again. This time, they are claiming that even stealthy fifth generation fighters and B-2 bombers cannot penetrate future threat arrays without unacceptable losses. They conclude that the Air Force...

    More so than in most other places, modeling and simulation are critical to training in Korea. Units in Korea do not have access to live combat training centers such as those found in the United States and Europe. Large-scale maneuver training areas, for example, are limited. Environmental and political restrictions severely limit training and traffic congestion curtails the ability of units to get to training areas. Modeling and simulations are a cost-effective means of overcoming these obstacles.

    Goldilocks isn’t the only one who demanded everything to be “just right.” The Earth and its fellow seven planets also needed perfect conditions to form as observed, and those right conditions occur rarely, a new computer simulation shows. The new simulation, described in the Aug. 8 Science, is the first to trace from beginning to end how planetary systems form from an initial gas disk encircling a baby star. “The really striking result of the new model is how chaotic and even violent the average story of a planet’s birth is,” says Edward Thommes, an astrophysicist now at the University...

    The multiverse theory has spawned another - that our universe is a simulation, writes Paul Davies. If you've ever thought life was actually a dream, take comfort. Some pretty distinguished scientists may agree with you. Philosophers have long questioned whether there is in fact a real world out there, or whether "reality" is just a figment of our imagination. Then along came the quantum physicists, who unveiled an Alice-in-Wonderland realm of atomic uncertainty, where particles can be waves and solid objects dissolve away into ghostly patterns of quantum energy. Now cosmologists have got in on the act, suggesting that what...
