### Pondering the Bits That Build Space-Time and Brains

Vijay Balasubramanian investigates whether the fabric of the universe might be built from information, and what it means that physicists can even ask such a question.

### Euler’s 243-Year-Old ‘Impossible’ Puzzle Gets a Quantum Solution

A surprising new solution to Leonhard Euler’s famous “36 officers puzzle” offers a novel way of encoding quantum information.

### The New Thermodynamic Understanding of Clocks

Investigations of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself.

### The Year in Math and Computer Science

Even as mathematicians and computer scientists proved big results in computational complexity, number theory and geometry, computers proved themselves increasingly indispensable in mathematics.

### The Most Famous Paradox in Physics Nears Its End

In a landmark series of calculations, physicists have proved that black holes can shed information.
