Dai Hanning

The provided articles do not mention Dai Hanning. Instead, they focus on a team led by Pan Jianwei at the University of Science and Technology of China in Hefei. This team has developed a highly precise strontium optical clock. This clock is newsworthy because of its exceptional accuracy; it is projected to lose or gain less than one second over approximately 30 billion years, which is more than twice the estimated age of the universe. This development places China among the leading nations in timekeeping technology and positions it to potentially influence the future redefinition of the second. The clock's precision could have significant implications for various scientific and technological fields that rely on accurate time measurements.
