John Bardeen

1908-1991 · condensed matter physics, quantum theory, electronics
American physicist, the only person to receive two Nobel Prizes in physics. The first for the invention of the transistor (the foundation of modern electronics), the second for the BCS theory of superconductivity. His works underlie many quantum devices.

Biography

Born in Madison, Wisconsin. Studied at the University of Wisconsin, PhD at Princeton. Worked at Bell Labs, then professor at the University of Illinois at Urbana-Champaign. Member of the National Academy of Sciences. Nobel laureate (1956, 1972).

Key discoveries

💡 Bardeen was very modest and avoided the limelight; upon hearing of his second Nobel Prize, he first went to play golf.
"He considered the main thing to be understanding how little we actually know, which opens the door to discoveries."

Magnetic Lego: Unexpected Flexibility in Atomic Layers
Imagine a stack of pancakes where each pancake is magnetized, but the magnetization directions in adjacent pancakes are opposite. That's exactly how this new magnetic material is arranged: in each atomic layer, all magnetic moments — the atom's 'arrows'—point in one direction, while the next layer is magnetized in the opposite direction.

Stretching a carbon sheet turns it into a superconductor

A Thin Film You Can Peel Off with Water
A thin film of a complex oxide is like a transfer tattoo: you need to carefully peel it off one surface and stick it onto another without tearing it.

It disappears in water within minutes, leaving the film intact.

Threads That Choose Their Own Shape
An octopus tentacle bends, grabs, and stretches — all without a single bone. The secret is that inside it, sections that contract alternate with sections that remain passive.

Now researchers have proposed 3D-printing elastic threads from two materials at once.
