A gargantuan rock-ice avalanche tumbled into the deep waters of a fjord in eastern Greenland, unleashing a megatsunami whose initial waves reached a height of 200 meters. The waves scoured the walls of the fjord before flowing into the open sea. Even for this avalanche-prone corner of Greenland, the collapse and subsequent megatsunami were shocking...

But they were discovered in the era of steam-driven technology, long before anyone dreamed of quantum mechanics. In this episode, the theoretical physicist Nicole Yunger Halpern talks to host Steven Strogatz about how physicists today are reinterpreting concepts such as work, energy and information for a quantum...

As a peak rose from the static on his monitor at the research institute JILA in Boulder, Colorado, Zhang dropped a screenshot in a group chat with his three lab mates. One by one they hopped out of bed and trickled in. After several sanity checks to make sure that what they...

Unfortunately, physicists have found it challenging to explain to everyone else how this so-called Higgs field accomplishes its mighty task. A common approach has been to tell a...

The evidence for both of them, however, hinges on assumptions that gravity works the same way at all scales. What if that’s not true? In this episode, theoretical physicist Claudia de...
