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.
So an interesting pursuit is to simulate quantum chromodynamics on a computer to see what kind of complexity arises. The promise is that simulating physics on such a fundamental level is more or less equivalent to simulating the universe itself.
There are one or two challenges of course. The physics is mind-bogglingly complex and operates on a vanishingly small scale. So even using the world’s most powerful supercomputers, physicists have only managed to simulate tiny corners of the cosmos just a few femtometers across. (A femtometer is 10^-15 metres.)
That may not sound like much but the significant point is that the simulation is essentially indistinguishable from the real thing (at least as far as we understand it).
It’s not hard to imagine that Moore’s Law-type progress will allow physicists to simulate significantly larger regions of space. A region just a few micrometres across could encapsulate the entire workings of a human cell.
Again, the behaviour of this human cell would be indistinguishable from the real thing.
It’s this kind of thinking that forces physicists to consider the possibility that our entire cosmos could be running on a vastly powerful computer. If so, is there any way we could ever know?
Today, we get an answer of sorts from Silas Beane, at the University of Bonn in Germany, and a few pals. They say there is a way to see evidence that we are being simulated, at least in certain scenarios.
In 2007 Villafane was contacted by High Noon Entertainment and asked to participate in the Food Network’s Challenge Show for a segment called “Outrageous Pumpkins”. He competed against three other professional pumpkin sculptors and won all three rounds to receive the grand prize. The Food Network contacted Villafane again in 2009 to come back to the show and defend his title. He was also the grand prize winner for the “Outrageous Pumpkin Challenge II”. In 2011, he carved the world’s biggest pumpkin to resemble zombies. From Wkipedia

Extractive states are controlled by ruling elites whose objective is to extract as much wealth as they can from the rest of society. Inclusive states give everyone access to economic opportunity; often, greater inclusiveness creates more prosperity, which creates an incentive for ever greater inclusiveness. Elites that have prospered from inclusive systems can be tempted to pull up the ladder they climbed to the top. Eventually, their societies become extractive and their economies languish.
Several recent studies have shown that in America today it is harder to escape the social class of your birth than it is in Europe. Educational attainment, which created the American middle class, is no longer rising.
Economists point out that the woes of the middle class are in large part a consequence of globalization and technological change. Culture may also play a role. In his recent book on the white working class, the libertarian writer Charles Murray blames the hollowed-out middle for straying from the traditional family values and old-fashioned work ethic that he says prevail among the rich (whom he castigates, but only for allowing cultural relativism to prevail).
The crony capitalism of today’s oligarchs is far subtler than Venice’s. It works in two main ways.
The first is to channel the state’s scarce resources in their own direction. This is the absurdity of Mitt Romney’s comment about the “47 percent” who are “dependent upon government.” The reality is that it is those at the top, particularly the tippy-top, of the economic pyramid who have been most effective at capturing government support — and at getting others to pay for it.
Exhibit A is the bipartisan, $700 billion rescue of Wall Street in 2008. Exhibit B is the crony recovery. The economists Emmanuel Saez and Thomas Piketty found that 93 percent of the income gains from the 2009-10 recovery went to the top 1 percent of taxpayers. The top 0.01 percent captured 37 percent of these additional earnings, gaining an average of $4.2 million per household.
Workers in UK and Poland have most generous statutory employee holiday entitlements
Employees in the USA, Canada, Philippines, China and Thailand have the least generous
Colombia has greatest number of public holidays; Mexico the least
UK employees have access to a highest amount of potential holiday (36 days per year) but in reality fare worse than other European employees
According to Mercer Consulting, holiday entitlement is often more complex since actual holiday provisions often depends on company contracts and the number and treatment of public holidays. In the UK, for example, employees are entitled to 28 days holiday. With the UK also holding 8 public holidays each year, this suggests that employees in the UK could be on holiday for 36 days, or 10%, of each year. This would be one of the highest entitlements of all 62 countries. The reality is that companies are allowed to include the 8 public holidays as part of the 28 day entitlement so UK employees actually have fewer days’ holidays than their peers in the rest of Europe where, in general, the practice is for European employees to take public holidays in addition to their statutory entitlement. Employees in the Asia-Pac region have comparatively low levels of statutory entitlement but public holidays are taken in addition to this rather than as part of it. However, the levels of holiday entitlement in Asia-Pac are still below those of Western Europe. Employee holiday entitlements around the world.
On Oct. 12, 1979, Super Typhoon Tip’s central pressure dropped to 870 mb (25.69 inches Hg), the lowest sea-level pressure ever observed on Earth, according to NOAA. Peak wind gusts reached 190 mph (306 kph) while the storm churned over the western Pacific.
Besides having unsurpassed intensity, Super Typhoon Tip is also remembered for its massive size. Tip’s diameter of circulation spanned approximately 1,380 miles (2,220 km), setting a record for the largest storm on Earth. The storm’s huge diameter was exactly the same as the distance from New York City to Dallas.
Excerpts from Sled Driver, the amazing book by one of the SR-71 pilots, Major Brian Shul:
In April 1986, following an attack on American soldiers in a Berlin disco, President Reagan ordered the bombing of Muammar Qaddafi’s terrorist camps in Libya. My duty was to fly over Libya and take photos recording the damage our F-111’s had inflicted. Qaddafi had established a ‘line of death,’ a territorial marking across the Gulf of Sidra , swearing to shoot down any intruder that crossed the boundary. On the morning of April 15, I rocketed past the line at 2,125 mph.
I was piloting the SR-71 spy plane, the world’s fastest jet, accompanied by Maj Walter Watson, the aircraft’s reconnaissance systems officer (RSO). We had crossed into Libya and were approaching our final turn over the bleak desert landscape when Walter informed me that he was receiving missile launch signals. I quickly increased our speed, calculating the time it would take for the weapons-most likely SA-2 and SA-4 surface-to-air missiles capable of Mach 5 – to reach our altitude. I estimated that we could beat the rocket-powered missiles to the turn and stayed our course, betting our lives on the plane’s performance
Chinese technocrats set out to create an industry that would dominate the world, and they succeeded. They aided solar cell manufacturers with easy credit from state banks—perhaps as much as $18 billion of cheap loans—and, some say, subsidies. As a result of central and local government support, Chinese manufacturers began to expand rapidly. Chinese competitors now own 70% of the world’s wafer-producing capacity.
Make that overcapacity. “Massive subsidies and state intervention have stimulated overcapacity more than 20 times total Chinese consumption and close to double total global demand,” said Milan Nitzschke, president of EU ProSun, in a statement released late last month. The company alleges that 90% of Chinese production had to be exported and that Beijing used subsidies to keep its manufacturers in business.
The powerful Chinese National Development and Reform Commission wants to see two-thirds of panel makers go out of business. Only the largest producers, which are presently nonviable, will survive.
In short, central government technocrats, to salvage their industrial policy, will now have to destroy what they worked so hard to create.
