A bit frustrated that we're finally getting clear nights when the moon is almost 90% full, I used a lens instead of a scope and worked on asterisms. This is the Sickle in Leo. It forms the head of the lion. The bright star at the bottom is Regulus. #Astronomy #Astrophotography

The newest and most powerful A.I. technologies — so-called reasoning systems from companies like OpenAI, Google and the Chinese start-up DeepSeek — are generating more errors, not fewer. As their math skills have notably improved, their handle on facts has gotten shakier.
