"The Twisted Universe: the cosmic quest to reveal which end is up"

The cosmic microwave background (CMB) has spectacularly advanced our understanding of the origin, composition, and evolution of our universe. Yet there is still much to glean from this, the oldest light in the universe. Powerful telescopes are plying the skies in a quest to discover new physics.

"On Ising's model of ferromagnetism"

"On Ising's model of ferromagnetism"

The 1D Ising model is a classical model of great historical significance for both classical and quantum statistical mechanics. Developments in the understanding of the Ising model have fundamentally impacted our knowledge of thermodynamics, critical phenomena, magnetism, conformal quantum field theories, particle physics, and emergence in many-body systems.

"How Fermi Became Fermi"

"How Fermi Became Fermi"

Enrico Fermi was one of the most significant figures of 20th century physics, with major contributions across a wide range of sub-disciplines. How did Fermi become Fermi? Drawing on research undertaken in preparation for his forthcoming biography of Fermi, “The Last Man Who Knew Everything: The Life and Times of Enrico Fermi, Father of the Nuclear Age” (Basic Books, December 5, 2017) David N.
