“As the world goes increasingly wireless, we’ve learned to tolerate a certain degree of failure in our wireless systems — like when your computer just won’t sync up with the wireless internet at the cafe, or when our phones drop a call. But what about situations when wireless systems simply cannot fail? A failure rate of zero is tough to achieve in any system, but computer scientists at Saarland University in Germany have demonstrated a wireless bicycle brake that works 99.999999999997 percent of the time. That means in a trillion braking attempts, it fails three times on average. It’s not perfect, mathematically speaking, but for practical purposes it’s pretty close.” w/ photo
