Computer Scientists Invent an Efficient New Way to Count
By making use of randomness, a team has created a simple algorithm for estimating large numbers of distinct objects in a stream of data.
Game Theory Can Make AI More Correct and Efficient
Researchers are drawing on ideas from game theory to improve large language models and make them more consistent.
New Breakthrough Brings Matrix Multiplication Closer to Ideal
By eliminating a hidden inefficiency, computer scientists have come up with a new way to multiply large matrices that’s faster than ever.
Scientists Find Optimal Balance of Data Storage and Time
Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it.
In a ‘Dark Dimension,’ Physicists Search for the Universe’s Missing Matter
An idea derived from string theory suggests that dark matter is hiding in a (relatively) large extra dimension. The theory makes testable predictions that physicists are investigating now.
How to Guarantee the Safety of Autonomous Vehicles
As computer-driven cars and planes become more common, the key to preventing accidents, researchers show, is to know what you don’t know.
A Century Later, New Math Smooths Out General Relativity
Mathematicians prove a theorem that illuminates the geometry of universes with tiny amounts of mass.
The Mathematician Who Sculpted the Shape of Space
Eugenio Calabi, who died on September 25, conceived of novel geometric objects that later became fundamental to string theory.
The Physical Process That Powers a New Type of Generative AI
Some modern image generators rely on the principles of diffusion to create images. Alternatives based on the process behind the distribution of charged particles may yield even better results.
