100 Mind-Blowing Measuring Facts
The highest mountain known to man is on an asteroid called Vesta. Measuring a whopping 22km in height, it is three times as tall as Mount Everest!
The Easter Island heads are more than just heads. During excavation, archaeologists unEarthed bodies on these massive stones, some measuring as tall as 33 feet.
Science has several different ways of defining time. To cover just a couple: There’s astronomical time, which is measured by how long it takes Earth to rotate on its axis. In astronomical time, a second is 1/60th of a minute. And then there’s atomic time, which dictates the numbers that you’ll see on a clock. According to atomic time, one second equals 9,192,631,770 oscillations of a cesium-133 atom. Measuring the vibration of an atom—which, in simple terms, is the gist of what oscillation is—is the most accurate way to track time.
You’ll find the most accurate clock at the National Institute of Standards and Technology in Boulder, Colorado. The clock keeps time by measuring the vibration of a single aluminium ion and should remain accurate for 33 billion years. The clock sitting on your bedside table isn’t quite as precise.
