The ruler length and width measurements reflected the largest bias, regardless of wound shape [8]. The standard error of measurement (SEM) is defined as the difference between an observed score and a true score, so the SEM is an indication of the imprecision of a measurement technique [17].
Washington: Runaway planets zipping through space at mind-numbing speeds of 30 million miles per hour are now the fastest objects in the universe, says a study. Seven years ago, the discovery of the first runaway star, shooting out of our Galaxy at a staggering speed of 1.5 million mph, set astronomers on a course of exploration.
Since you already know that light is the fastest thing around, we'll look at what other speedy items our universe, and maybe even a fictional universe or two, has to offer -- from animals to superheroes and planets to toilets. Because, yes, it stands to reason that if toilets can move, then there must be one that moves fastest. And don't tell me you're not curious to know which one holds that honor. So leash your cheetah, tell Usain Bolt to take a knee and buckle your seat belt as we power through our list of fastest things.
