Yves Meyer makes wavelets with his mathematical theory

On May 23rd, King Harald V of Norway, will present the Abel Prize to French mathematician Yves Meyer. Each year, the prize is awarded to a laureate for "outstanding work in the field of mathematics". Yves Meyer makes wavelets with his mathematical theory The French mathematician will next week receive the Abel Prize for his work On May 23rd, King Harald V of Norway, will present the Abel Prize to French mathematician Yves Meyer. Each year, the prize is awarded to a laureate for "outstanding work in the field of mathematics". The award is comparable to a Nobel Prize, and is named after the exceptional Norwegian Niels Henrik Abel, who, in a short life from 1802 to 1829, made dramatic advances in mathematics. Meyer was chosen for his development of the mathematical theory of wavelets. In the early 1980s French engineer Jean Morlet proposed a powerful new way of analysing seismic data to…

10 unsolved problems in computer science, explained

These 10 unsolved problems in computer science, from P versus NP to quantum advantage, bear on cryptography, algorithm design and computing's limits — here is what each asks That distinction sounds abstract, but it decides what is feasible. A problem solvable in polynomial time can usually be handled at scale. A problem that appears to need exponential time can stall the fastest hardware on inputs of modest size. Each extra element in the input can double the work. Security systems and logistics software both depend on which side of that line certain problems fall. P versus NP asks whether every problem whose solution a computer can check quickly can also be solved quickly. No one has proved the answer either way. The two labels name classes of problems. P covers problems a computer can solve in polynomial time. NP covers problems where a proposed answer can be verified in polynomial…

The Credence Good of Inference Compute

In microeconomics, a credence good is any purchase where the consumer cannot assess the marginal utility of the service even after paying for it. The classic textbook example is an automotive repair shop. If a mechanic replaces an alternator and the car starts, you know the outcome is acceptable. You have no way of knowing whether the car actually required a new alternator or a loose ground wire tightened with a quarter turn of a wrench. The information asymmetry belongs entirely to the seller. Over the past year, frontier foundation model providers have packaged inference compute into the exact same economic structure. Instead of selling raw text completion, labs offer reasoning models equipped with an ordinal dial: low, medium, high, and maximum effort. The marketing premise sounds straightforward. If a problem is easy, the system answers quickly. If a problem requires multi-step…

A ‘simple’ math problem has divided people 50/50. It’s a great metaphor for social division.

Half say the answer is 9, half insist it’s 1. What if they’re both right? In theory, a math problem involving four single digits and basic arithmetic—no algebraic functions, no variables, no exponents—should be easy for any high school graduate to solve. So why are people split right down the middle on the answer to this seemingly simple problem? You may have gotten 9. You may have gotten 1. If you take this poll shared by World of Statistics on X, you’ll see how others answered. As of this article’s writing, over 1.3 million people have voted, and the split is nearly 50/50. 6 ÷ 2 (1 + 2) =— World of Statistics (@stats_feed) October 26, 2026 6 ÷ 2 (1 + 2) =— World of Statistics (@stats_feed) October 26, 2026 We’ll get into the actual math problem and why people are so split on the solution shortly. But to me, the debates surrounding it represent something bigger. Nearly every element of…
