Generate Key Takeaways Possibly originating with the English poet Geoffrey Chaucer's "time and tide wait for no man," the idea that time waits for no man has been around for a long time. But time, or at least the latest best measurement of it, has waited 20 years for the latest "most accurate" clock ever made - an ion or atomic "quantum logic" timepiece that measures to the 19th decimal place, making the priciest wristwatch seem like a sundial in comparison. In work published in the journal Physical Review, developers based at the US National Institute of Science and Technology (NIST) said the device uses quantum computing techniques to "pair an electrically charged aluminium atom (ion) with a magnesium ion." NIST claimed the new clock to have accuracy "41% greater than the previous record" and to show "a threefold reduction in instability" compared to the previous best atomic clocks. The previous record-holder, developed by NIST and the University of Colorado Boulder, could "detect the effects of gravity predicted by the theory of general relativity at the microscopic scale," NIST said in 2024. The record-busting new clock has been "under continuous development for 20 years," according to NIST, which said the work would help define the second more accurately, a development it believes could herald "new scientific and technological advances." The new clock's ticks are more stable than those of caesium, the provider of the current scientific definition of the second, according to NIST's David Hume. Hume's colleague Mason Marshall believes that fine-tuning the measurement of time "can push the field of physics and our understanding of the world around us." Listed since 1960 as "an international standard unit of measurement for time," the second was at first defined or measured by the rotation of the Earth relative to the cosmos. But because that rotation can slow down and speed up depending on factors such as the pull of the Moon - posing "a challenge for accurate timekeeping," according to NIST - the definition was changed in 1967 to one based on energy levels in atoms. Another redefinition is likely over the coming decade, NIST said in 2023.

187 students awarded degrees at 1st NIST convocation
Berhampur: Degrees were presented to 187 students, including 10 recipients of the prestigious Gold Medal and 19 recipients of Silver Medal, for exemplary academic performance as the National Institute of Science and Technology (NIST) University held its first Convocation Ceremony on Tuesday. The occasion marked a significant milestone in the university's journey, celebrating the achievements of its first graduating cohort. Additionally, honorary Doctorate degrees were conferred on distinguished space scientist and Padma Shri awardee Kota Harinarayana for his contribution to science, and eminent Odia vocalist Namita Agrawal for her contributions to literature and culture. NALCO CMD B Pratap Singh was the Chief Guest during the ceremony. The ceremony was further illuminated by the participation of renowned Odissi danseuse and Padma Shri awardee Aruna Mohanty as the Guest of Honour. Sukanta Kumar Mohapatra, Founder and Chairman of NIST University, inspired the graduates by highlighting their accomplishments both on national and international platforms. He also announced the establishment of a 'Centre of Excellence' within the university premises. NIST, established in 1996, has graduated more than 20,000 students from across India and nearby countries. NIST, which previously had autonomous college status, was granted university status in 2024 by the State government through enactment of the NIST University Act. Upon being declared a university, several global innovation centres (GICs) are being set up in NIST to retain its unique position in the field of education and research.
