Dicing an Onion, the Mathematically Optimal Way

news.ycombinator.com The Pudding 2025-11-19 06:54:19

This is a project about onions and math. Why? Because tens of millions of people are curious about how to properly dice an onion, according to YouTube. In 2021, chef and food writer J. Kenji López-Alt broke out some math to get optimal uniform piece sizes. But there is more than one way to dice an onion… This is an onion. (Well, a simplified cross-section of one.) We’ve cut it in half lengthwise, using a sharp knife to reduce the chance of injury and onion-induced crying. From here, what’s the

Film Schools Are Embracing AI. Should They?

Jake Panek, a 20-year-old film major, says he’s had a great time at DePaul University in Chicago, and a very positive experience with the school’s cinema program. However, a recent email alerting students to a new course in “AI screenwriting” triggered a wellspring of untapped rage in him. The email, which was circulated last week, offered undergrads the opportunity to examine “the rapidly evolving role of artificial intelligence in the screenwriting process” and to help students “explore how A

How a mysterious particle could explain the Universe’s missing antimatter

arstechnica.com Unknown 2025-11-19 04:15:17

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current theories, matter and its counterpart, antimatter, ought to have been created in equal amounts at the time of the Big Bang. But antimatter is vanishingly rare in the universe. So what happened? Physicists don’t know the answer to that question yet, but many think the solution must involve some subtle dif

A brazen attack on air safety is underway — here’s what’s at stake

theverge.com Darryl Campbell 2025-11-19 05:00:00

At the end of July, the National Transportation Safety Board (NTSB) convened a three-day public hearing to investigate January’s mid-air collision over Washington, DC that killed 67 people. After the hearing, two conclusions were inescapable. First, the disaster should have been prevented by existing safety rules. And second, the government regulators responsible for air safety have become hesitant to enforce those rules, especially when it means standing up to industry demands for more flights

Taiwan’s “silicon shield” could be weakening

Squarely in the middle Taiwan’s modern security uncertainties stem from the long-contested issue of the island’s sovereignty. After losing the first Sino-Japanese War in the late 1800s, the Qing dynasty forfeited Taiwan to Japanese imperial control. It was Japan’s “model colony” until 1945, when postwar negotiations resulted in its transfer to the Republic of China under Chiang Kai-shek of the Nationalist Party, known as the KMT.
