Early in his career, Karl Jakobs worked on physics experiments that had a few hundred collaborators and operated for roughly a decade. “In the 1980s and 1990s, the experiments were smaller, and there ...

The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists ...

3. It all adds up to 85%. Amazingly, despite being unclear on precisely what dark matter is, astrophysicists do know pretty well how much of it there is—which is why we can say that it accounts for 85 ...

2. Gravity and weight are not the same thing. Astronauts on the space station float, and sometimes we lazily say they are in zero gravity. But that’s not true. The force of gravity on an astronaut is ...

Round 1: The Proton Pay heed to this smashing subatomic celebrity, used in medicine and to produce neutrinos, antiprotons and, of course, the God particle. Step aside, lightweights. The proton has ...

The hidden neutrino As we experimentally observe them now, neutrinos cannot interact with the Higgs field because they’re are missing something vital: They are not right-handed. Particles can be ...

There are no tricks, only treats, when you add science to your annual pumpkin-carving festivities. That’s why we at Symmetry created designs featuring spooky versions of important figures from the ...

Nima Arkani-Hamed Professor, Institute for Advanced Study in Princeton Theoretical physicist In Particle Fever, theorist Nima Arkani-Hamed says on camera, “I’ve spent the last 15 years thinking about ...

Every six months on the spring and autumn equinoxes, a serpent slithers down the side of the El Castillo pyramid in Chichén Itzá, Mexico. Well, it’s not a real serpent—it’s an optical illusion caused ...
