  1. New blog post: “There are two kinds of theorems”.

    Mathematics alternates between model-building and model-using. After the model building comes a series of theorems showing that the model works and makes sense. And then come the real theorems, the new ones about the thing that was being modeled.

    This is perhaps the most important mathematical methodology, and it is never explained to the students, who are left wondering why Euclid proves a lot of theorems about things that are obvious (“vertical angles are equal”) or why we show that the Peano axioms can prove the commutativity of addition.

  6. 💁🏻‍♀️ TIL: 🥚✏️ Engraved #ostrich eggshells dating to over 60,000 years ago, from sites including #Diepkloof and #Apollo11, were systematically analyzed.

    Over 80% of 112 fragments showed consistent spatial rules, with repeated right angles and parallel lines. The researchers argue this rule-based organization points to planned abstract thought and early symbolic systems.

  11. A perimeter is the length of a closed boundary that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional line. The perimeter of a circle or an ellipse is called its circumference.

  16. 💁🏻‍♀️ ICYMI: 🏛️📐 Egyptologist Laurel Bestock breaks down five major archaeological findings behind the #construction of the #GreatPyramid of #Giza.

    Her breakdown covers ancient stone quarrying, mud-brick ramps, worker housing, transport logbooks, and earlier pyramid designs that led to Giza.
