The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

In June, the US National Academies of Sciences, Engineering, and Medicine published an unprecedented 40-year strategy for US ...

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 ...

In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped of ...

An experiment deep underground hopes to explain the gallium anomaly. The gallium anomaly dates back 20 years to a confusing experimental finding. The answer could represent a fundamental shift, or it ...

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 ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

Luther College Physics Professor Todd Pedlar has received his seventh consecutive National Science Foundation (NSF) research grant. Since 2006, NSF grants have allowed Pedlar and Luther students to ...

Researchers at Fermilab, who run the Tevatron particle accelerator, say they’ve discovered a new particle “anomaly,” leading people to think they may have uncovered a new elementary particle or new ...
