You may have heard about OpenAI solving a $1 million math problem. Sounds like a big deal, and it is! But while the equation is commonly used in engineering, nobody expects anything to really change, at least immediately. www.scientificamerican.com/article/what...

What does OpenAI’s fluid-dynamics breakthrough mean for real-world engineering?
OpenAI’s claimed proof of the Navier-Stokes problem is a mathematical tour de force, but any real-world applications may be years away—if they ever arrive at all

Thank you to @sciam.bsky.social for letting me dig into the protein enhancement fad. 1. If you are an elite athlete, OR elderly/frail, maybe you do need extra protein. 2. That's not you. You're not an elite athlete. 3. If it is you: consider yogurt. www.scientificamerican.com/article/prot...

Are protein-boosted foods and drinks actually more healthy?
Extra protein can be found in everything now, from potato chips to Pop-Tarts. Does this benefit the average eater?

At bottom, a graphic showing the altitudes at which the capsule's parachutes will deploy.A graphic of the Artemis II reentry timeline. The process takes 13 minutes for the capsule to travel from 400,000 feet above Earth down to the ocean. Also marked are a communications blackout spanning from about 30 seconds to 6 minutes into the process and the parachute deploy from 10 to 12.5 minutes.
