Is math big or small?
2026-04-13A recent article exploring the concept of scale in mathematics has sparked a debate among readers about whether abstract concepts possess an inherent size. Commenters argue that mathematical shapes lack a defined scale without physical context, suggesting that magnitude is entirely dependent on the observer's perspective and frame of reference. Ultimately, the discussion highlights that the perceived scale of mathematics is dictated by its real-world applications and the underlying purpose behind its use.
Michigan 'digital age' bills pulled after privacy concerns raised
2026-04-13Michigan lawmakers withdrew proposed digital age legislation following backlash over its handling of consumer data privacy. Critics argued the bills relied on flawed opt-out mechanisms rather than requiring strict opt-in permission for data sales. The controversy highlights broader frustrations with tech companies using delayed consent models to harvest user data for AI training without explicit approval.
