Never-Repeating Patterns of Tiles Can Safeguard Quantum Information

This extreme fragility might make quantum computing sound hopeless. But in 1995, the applied mathematician Peter Shor discovered a clever way to store quantum information. His encoding had two key properties. First, it could tolerate errors that only affected individual qubits. Second, it came with a procedure for correcting errors as they occurred, preventing them … Read more

Google can now solve trickier math problems for you with these new features

Google Math is a challenging subject because it requires an understanding of how to perform the operation to reach an answer, which makes it more difficult to Google an equation to find the answer difficult — until now.  Google added new updates to Search and Lens that make it easier for users to get assistance … Read more

Alan Turing and the Power of Negative Thinking

Turing’s diagonalization proof is a version of this game where the questions run through the infinite list of possible algorithms, repeatedly asking, “Can this algorithm solve the problem we’d like to prove uncomputable?” “It’s sort of ‘infinity questions,’” Williams said. To win the game, Turing needed to craft a problem where the answer is no … Read more

Racial gaps in math have grown. A school tried closing theirs by teaching all kids the same classes

Hope Reed was seeing stark disparities a decade ago at her high school in the suburbs of Columbia, South Carolina. Nearly half the school’s students were white, but the freshman remedial math classes were made up of almost all students of color. Reed, then chair of the math department at Blythewood High School, intervened with … Read more

Two divergent skills that matter in an AI world: Math and business development

Dmitriy Sidor/Getty Images Artificial intelligence (AI) keeps upending our ideas about future skill requisites in interesting ways. On one level, AI requires a deep understanding of underlying technology, data science, and statistics. At the same time, AI also calls for less immersion in underlying technicalities and an ability to keep an eye on business advantage.  … Read more

A New Proof Strikes the Needle on a Sticky Geometry Downside

The unique model of this story appeared in Quanta Journal. In 1917, the Japanese mathematician Sōichi Kakeya posed what at first appeared like nothing greater than a enjoyable train in geometry. Lay an infinitely skinny, inch-long needle on a flat floor, then rotate it in order that it factors in each path in flip. What’s … Read more

The Lawlessness of Giant Numbers

The unique model of this story appeared in Quanta Journal. Up to now this 12 months, Quanta has chronicled three main advances in Ramsey idea, the examine of learn how to keep away from creating mathematical patterns. The primary consequence put a brand new cap on how huge a set of integers might be with … Read more
