    We trust the scientists around us to have the best grasp on how the world actually works. So at this year's 2016 Isaac Asimov Memorial Debate at the American Museum of Natural History, which addressed the question of whether the universe is a simulation, the answers from some panelists may be more comforting than the responses from others. Physicist Lisa Randall, for example, said that she thought the odds that the universe isn't "real" are so low as to be "effectively zero." A satisfying answer for those who don't want to sit there puzzling out what it would mean for...
  • Spoiler Alert: People With No Firearms Training Get Killed In Self-Defense Simulator

    Okay. I mean, this shouldn’t be a shocker, but people who have no firearms training didn’t survive the firearms training simulator located at Prince George's County Police Department in Maryland. Another non-surprise is that police officers did well; though some might add that concealed carry holders spend more time at the range than police officers. Regardless, the Washington Post  reported on how determining life and death situations–and when to use deadly force–is difficult; something that any gun owner, or person with common sense, would already know: [A] new study from researchers at Mount St. Mary's University sheds some light on why people...

Right on time, Lexus has presented the latest example from its "Amazing in Motion" series of video spectacles: the Lexus Hoverboard. As you can see in the video after the break, it certainly appears to hover, and smoke, but no one actually hops on the magnetically-levitating device for a ride.

    ( – 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...

    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.

    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....

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.

    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.

    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...

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...

    If an asteroid like this one, depicted in an artist's drawing, hit Earth's oceans, it could generate huge waves that would move more slowly than previously thought, but in the end, cause more damage. Asteroid Tsunamis Could be Huge, Slow By Larry O'Hanlon, Discovery News normalize font   |   increase font June 7 — Just when you thought it was safe to go in the water, a new supercomputer model predicts that meteors and asteroids splashing down in the oceans can create waves twice as big, but slower moving, than previous estimates. In other words, if Earth gets walloped...

    I play an online political game called the National Government Simulation (NGS). On discussion boards, we roleplay the House of Representatives, the Supreme Court, the Presidency, and the Cabinet. When members join, they automatically become Congressmen. I serve as the Deputy Majority Leader for Outreach. Our elections are coming up and we face a stiff fight against the "Left Coalition." We need recruits. NGS provides a chance for participants to write and push for legislation, to learn the dynamics of allies and enemies, and to challenge and refine their own ideology or message. If you would like to join, please...
