The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...
Physics has demonstrated that the everyday phenomena we experience are governed by universal principles applying at time and distance scales far beyond normal human experience. Physics has ...

Quarks are among the smallest things that science has discovered, shown experimentally to be about a million billion times smaller than a grain of sand. Joshua Jackson, Luther College senior of East ...
In the 1990s, the Liquid Scintillator Neutrino Detector (LSND) in Los Alamos, New Mexico, found a weird anomaly during its experiments on tiny elementary particles called neutrinos. It found far more ...
Every few years, scientists take a step back to take a broader look at their field and determine what questions are most pressing—and what tools they will need to answer those questions. This year the ...
