In principle, a nuclear clock should be more precise and more stable than an optical clock (pictured).Credit: Andrew Brookes, National Physical Laboratory/Science Photo Library Scientists have taken a major leap towards making an entirely new type of clock — one based on tiny shifts in energy in an atomic nucleus. In principle, a nuclear clock … Read more

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

by

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 of … Read more
