### Physicists Puzzle Over Emergence of Strange Electron Aggregates

Electrons have been seen uniting into entities with fractions of electric charge, this time without a magnetic field coaxing them into it.

### The S-Matrix Is the Oracle Physicists Turn To in Times of Crisis

Particle physicists in search of the next theory of reality are consulting a mathematical structure that they know will never fail: a table of possibilities known as the S-matrix.

### He Seeks Mystery Magnetic Fields With His Quantum Compass

Alex Sushkov is updating an old technology with new quantum tricks in hopes of sensing the magnetic influence of dark matter.

### Will Better Superconductors Transform the World?

Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.

### Scientists Find a Fast Way to Describe Quantum Systems

After years of false starts, a team of computer scientists has found a way to efficiently deduce the Hamiltonian of a physical system at any constant temperature.

### Can Information Escape a Black Hole?

Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host Janna Levin about the black hole information paradox and how it has propelled modern physics.

### What Is Quantum Teleportation?

Teleporting people through space is still science fiction. But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.

### Physicists Finally Find a Problem for Quantum Computers Alone

Researchers have shown that a problem relating to the energy of a quantum system is easy for quantum computers but hard for classical ones.

### What Is the Nature of Time?

Time is all around us: in the language we use, in the memories we revisit and in our predictions of the future. But what exactly is it? The physicist and Nobel laureate Frank Wilczek joins Steve Strogatz to discuss the fundamental hallmarks of time.
