...distributed across your palm. Push your hand against a corner, and the stress becomes impossible to compute reliably. But if you can figure out how much effort you're using (force), stress becomes much easier to calculate. That's Verity's key. The result: with unprecedented precision, engineers can predict how long a welded joint will last. Meaning? Car companies like Ford spend years and millions of dollars testing welds. Dong says Verity makes 90% of that redundant. --By Matt Smith
...should help make omega clear.) Suffice it to say that the concept broadens two major discoveries of 20th century math: Gödel's incompleteness theorem, which says there will always be unprovable statements in any system of math, and Turing's halting problem, which says it's impossible to predict in advance whether a particular computer calculation can ever be finished...
...petrol that was suddenly in short supply. The scenes of idle gas pumps and irate drivers, which evoked memories of oil shocks of the 1970s, were the result of weather-related supply disruptions, according to the government. The fuel flow was quickly restored, but no one is willing to predict the gas lines won't recur...
...cost, some MRI experts predict that will become less of an issue. "Right now many heart patients have to undergo a combination of tests that add up to more than the expense of one MRI scan," says Dr. Andrew Arai, a researcher at the National Heart, Lung and Blood Institute in Bethesda, Md., who is studying the use of cardiac MRI in the emergency room. If a single MRI could replace the need for lots of echocardiograms, cardiac catheterizations and nuclear perfusion scans, it might be worth the price...
...something they have always known was present in problem vessels: calcium. Hospitals, clinics and even gyms are touting quick and easy scans that can measure the amount of calcium in your coronary arteries in minutes. But while calcium scores can be helpful, doctors caution that using them to predict who is at risk of heart disease isn't always straightforward...
