V_4_04 — Unsolved Problems in Mathematics

Mathematics has always been driven by problems that resist solution — conjectures so deep that their resolution reshapes entire fields. The Clay Mathematics Institute's seven Millennium Prize Problems ($1 million each, a

V_2_09 — Number Theory: Primes, Patterns, and Unsolved Problems

Number theory — the study of integers and their properties — is one of the oldest and most beautiful branches of mathematics, yet it connects to cryptography, physics, and computer science in profound ways. Prime numbers

G_3_24 — Post-Normal Science: Funtowicz, Ravetz, and Uncertainty

Post-normal science (PNS) is a framework for understanding and managing scientific inquiry when facts are uncertain, values in dispute, stakes high, and decisions urgent — conditions that characterize many of the most cr

V_1_10 Verified Mathematics & Information

V_1_10 — Ancient Greek Mathematics

Ancient Greek mathematics (c. 600 BCE – 500 CE) transformed mathematics from a collection of empirical recipes into a deductive science built on axioms, definitions, and rigorous proof. Thales of Miletus (c. 624–546 BCE)

V_3_06 — Differential Equations: Modeling Change and Dynamics

Differential equations describe how quantities change and are the primary mathematical language of physics, engineering, biology, and economics. From Newton's second law (F = ma, a second-order ODE) to Einstein's field e
