JILA and NIST Fellow Jun Ye and his team's revolutionary work on nuclear clock technology was recently highlighted in a feature by Scientific American. The article delves into the creation of the world’s first nuclear clock, developed in Boulder, Colorado, which builds upon decades of research into precision timekeeping. Nuclear clocks, which rely on the ticking of atomic nuclei rather than atomic electrons, promise to surpass the precision and accuracy of current atomic clocks, which have set the standard for international timekeeping for decades.
