Atomic clock keeps ultra-precise time aboard a rocking naval ship

by

[ad_1] An atomic clock that keeps time with the help of iodine molecules is sturdy enough to withstand a sea voyage.Credit: Will Lunden Atomic clocks are usually either ultra-precise or sturdy, but not both. Now, scientists have created a precise clock that, when put through its paces aboard a naval ship, wavered by only 300-trillionths … Read more
