The “pinball” model of a slipping fault line borrows from the mathematics of avalanches.
The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing.
Freeman Dyson — physicist, mathematician, writer and idea factory — died on February 28, but his vitality lives on.

While the age-old chicken-and-egg paradox is easily answered, the question of infinite regress in physics is far from resolved.
A study has cemented the link between an intense global warming episode 56 million years ago and volcanism in the North Atlantic, with implications for modern climate change.
