Two glowing nucleons in a nucleus exchanging a bright meson across the tiny gap between them

Hideki Yukawa and the Meson: How a Force’s Rang...

In 1934 Hideki Yukawa asked why the force that holds the nucleus together reaches only about the width of a proton. His answer: a force carried by a particle with...

An ancient dim halo star glowing above a distant spiral galaxy

The Cosmological Lithium Problem: Big Bang’s Mi...

The Big Bang’s first minutes forged hydrogen, helium and a trace of lithium, and the theory matches deuterium and helium beautifully. Lithium-7 is the odd one out: the oldest stars...

Nucleus drawn as nested glowing shells, the closed shells shining brightest

Maria Goeppert Mayer: What Are Nuclear Magic Nu...

Nuclear “magic numbers” are proton or neutron counts that make nuclei unusually stable. Maria Goeppert Mayer and J. Hans D. Jensen explained them with a shell model including spin–orbit coupling;...

A tightly packed nucleus of red protons and blue neutrons bound by crackling sparks of the strong force, with faint electron orbits

What Holds the Nucleus Together? The Strong For...

Protons repel each other, yet nuclei hold together. The answer is the strong force, first pictured by Hideki Yukawa as an exchange of mesons and now understood through quarks and...
