In a chilling new book, theoretical physicist Carlo Rovelli says we’re back on the brink – and this time, leaders chronically lack the nous of Kennedy and Khrushchev. So why is he against rearming?

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

In our world of AI-dominated algorithms, some nuclear physicists prefer to do science the old-fashioned way. And this newly developed physics-based, AI-free algorithm may be the breakthrough needed ...

She laid much of the theoretical groundwork for the atomic bomb, although she did not participate directly in its production. By Special to The New York Times This obituary was originally published on ...

Nuclear isomers are crucial probes for studying the structure of nuclei. Unlike chemical isomers—which have the same chemical formula but different arrangements of atoms—nuclear isomers are nuclei ...
