At an event today in Rome, Andrea Stroppa praised El Salvador’s AI tutor program, which uses SpaceXAI’s Grok. In 171 public schools, 1,198 students posted reading, math & science scores matching Germany and Sweden. El Salvador is expanding this to 5,000+ schools & 1M+ students.

BREAKING: The U.S. State Department announced @Starlink as one of seven new technology partners in First Lady Melania Trump’s Fostering the Future Together initiative for children. Starlink’s role includes: • Papua New Guinea: Starlink is working with the government and NICTA to expand fast, reliable internet nationwide. This work was previously announced and builds on $30 million in U.S. support for satellite connectivity. • Uganda: N50 is launching an education pilot with Starlink, Intel, Arizona State University and Arrow Electronics, providing online and offline internet access to 10,000+ students and about 200 teachers. • Global reach: The seven technology partners are announcing partnerships across more than 15 nations to expand educational and technological opportunities for children. Starlink continues to connect communities and create opportunities worldwide.

Engineering Made Simple

The identity ⎡1 0 0⎤ ⎢0 1 0⎥ ⎣0 0 1⎦ does nothing, and that is its power. It is the multiplicative unit Cayley introduced when, in 1858, he turned a rectangular array of numbers into an algebra with its own addition and multiplication. Two millennia earlier the same arrays already solved simultaneous equations by column operations in The Nine Chapters. Seki Takakazu (1683) and Leibniz (1693) independently extracted from the square case a single number—the determinant—that decides whether a unique solution exists. Sylvester merely named the array a matrix in 1850; Cayley supplied the operations that made the name into structure. The same objects now encode rotations, quantum evolution, and the weights of every neural network.

Calculus was not invented in a single moment. Newton developed his ideas in the mid 1660s, while Leibniz developed an independent approach in the 1670s and published first in 1684, giving us the notation ∫ and dy/dx that still defines how we write calculus today. The story then shifted from finding powerful methods to making them rigorous. Cauchy’s work on limits and continuity in the 1820s laid the foundation, while Weierstrass later made the ε–δ language of analysis standard. The important lesson is that calculus evolved twice: first as a tool for solving problems, then as a precise theory explaining why those solutions work.

Remember who we're fighting for.
