A UK company has reached a temperature of minus 273.149996°C in the quantum technology it uses in its atomic clock, effectively creating the coldest place in the universe. It’s a high-tech solution for an age-old problem: accurate navigation at sea without the support of satellite systems.
Alexander Jantzen, Co-founder & Chief Operating Officer at Aquark Technologies, explains: “At the beginning of the 18th century, knowing your latitude when navigating was long understood by observing the position of known distant stars above the horizon, however the longitude was a dangerous mystery. The longitude problem comes from the fact that our planet rotates, and we have no fixed point of reference to compare with when out at sea.”
The solution to this problem came in 1735 when John Harrison developed the first practical marine chronometer.
“The solution to navigation accuracy was – and still is – precise timing,” says Jantzen. “Harrison solved the longitude problem, showing how accurate positioning was possible with the chronometer (the most reliable timekeeper in its day). He compared the time from a known location – such as where the ship set sail from – with the time of day where the ship was located. Knowing the difference in
