The Animal Origins of Coronavirus and Flu
Zoonotic diseases like influenza and many coronaviruses start out in animals, but their biological machinery often enables them to jump to humans.
How Pi Connects Colliding Blocks to a Quantum Search Algorithm
A curious physicist has discovered an unexpected link between theoretical block collisions and a famed quantum search algorithm.
Why the Laws of Physics Are Inevitable
By considering simple symmetries, physicists working on the “bootstrap” can rediscover the basic form of the known forces that shape the universe.
Quantum Supremacy Is Coming: Here’s What You Should Know
Researchers are getting close to building a quantum computer that can perform tasks a classical computer can’t. Here’s what the milestone will mean.
How (Relatively) Simple Symmetries Underlie Our Expanding Universe
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.
How Randomness Can Make Math Easier
Randomness would seem to make a mathematical statement harder to prove. In fact, it often does the opposite.
Why Mathematicians Can’t Find the Hay in a Haystack
In math, sometimes the most common things are the hardest to find.
The Strange Numbers That Birthed Modern Algebra
The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math.
A Short Guide to Hard Problems
What’s easy for a computer to do, and what’s almost impossible? Those questions form the core of computational complexity. We present a map of the landscape.
