The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

Complexity theory is a branch of computer science that studies the resources required to solve computational problems, particularly focusing on the classification of problems based on their inherent ...

Everyone’s always talking about traveling through time, but if you ask me the ultimate temporal vacation would be just to pause the clock for a bit. Who among us couldn’t use a five or six month break ...

Martino’s first steps in research were firmly rooted in psychology. As an undergraduate, she studied mindset theory and ...

Seeking to reduce the computing power needed for the widely used dynamic mode decomposition algorithm, a team of researchers in China led by Guo-Ping Guo developed a quantum-classical hybrid algorithm ...

The most widely used technique for finding the largest or smallest values of a math function turns out to be a fundamentally difficult computational problem. Many aspects of modern applied research ...

As algorithms play a growing role in determining content, critics say the results are often filled with biases. Women see ads for lower paying jobs and African-Americans for cheaper neighborhoods. Can ...

Complexity theory is a fundamental branch of theoretical computer science that categorises computational problems according to their inherent difficulty and the resources required to solve them. At ...
