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.
The Fastest-Spinning Known Millisecond Pulsar in the Galactic Field Using observations across the entire electro-magnetic spectrum, astronomers have discovered a radio pulsar spinning 707 times every second, making it the fastest known spinning pulsar in the Galactic field and the second fastest known overall. The pulsar emits pulsed electromagnetic radiation at very low radio frequencies and very high gamma-rays, while the low-mass binary companion, heated by the energetic radiation from the pulsar, is detected at optical wavelengths.
