After the passing of physicist Anthony Leggett, columnist Karmela Padavic-Callaghan remembers their personal connection with ...

NYU researchers created a new type of time crystal suspended in mid-air Sound waves move floating beads in rhythmic patterns, defying basic physics. The experiment reveals motion and energy transfer ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Physicists saw excitons, a type of quasiparticle, undergo a reversible phase transition from superfluid to supersolid for the first time, opening new doors for studying extreme states of matter. When ...

Time feels like the most basic feature of reality. Seconds tick, days pass, and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Learn how to analyze motion graphs in physics, including position-time and velocity-time graphs. This video explains slopes, areas, and motion behavior to help you clearly interpret real physics ...

Dear Annie: I’m 54, and my boyfriend is 57. We’re in a long-distance relationship, 1,700 miles apart. It’s been going on for almost two years now. I’ve flown to see him three times, and he wants to ...

No matter how many times I’ve been told (or written about) the importance of a slow run, I cannot translate it into my training. This is not to say that I am the fastest runner. My goal half marathon ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

There’s that nagging voice again: “Put the phone away. No, really this time.” But we don’t; 84 percent of Americans say that they are online either several times a day or “almost constantly.” “On your ...
