Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...

In at least one respect, all time loop stories repeat themselves endlessly. The protagonists — Bill Murray in “Groundhog Day,” Tom Cruise in “Edge of Tomorrow,” Andy Samberg in “Palm Springs” — start ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time without an external driver. Contrary to previous assumptions, quantum ...

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 ...

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...

At the turn of the 20th century, the renowned mathematician David Hilbert had a grand ambition to bring a more rigorous, mathematical way of thinking into the world of physics. At the time, physicists ...

The universe is decaying much faster than thought. This is shown by calculations of scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 10^78 years ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

The film discusses the evolution of navigation and the principles of buoyancy, stability, and propulsion in watercraft. It explains how objects float based on the displacement of water and the balance ...

The Israeli military launched a wide-scale operation last month against militants in several cities in the West Bank. Now, roughly 40,000 Palestinians have fled their homes — the highest since Israel ...
