Standard symmetric cryptographic primitives rely heavily on lookup tables and bitwise permutations over binary Galois fields. Serving as an accessible overview of a broader research paper I have written on a novel cryptographic architecture, this article explores an alternative S-box design by bridging abstract algebra and differential calculus. By extending

Every day, thousands of fund managers spend hours estimating risk, comparing returns and testing how their portfolios might behave in the future. Artificial intelligence can run many of these calculations in minutes. Beating the very best fund managers takes more than arithmetic, but beating most of them may not. This

Introduction Have you ever been in an unfamiliar place and need to get somewhere? The solution, inevitably, is to go on Google Maps and mindlessly follow its route. But have you ever wondered how it finds the fastest way so quickly? After all, there are millions of possible routes that

How Mathematics Designs the Perfect Defence Introduction Mathematics is often portrayed as a subject concerned merely with numbers, equations, and artistic problems. However, mathematics can also be used to model how everyday real systems work. One instance of such a mathematical idea is from over 2000 years ago, called Zeno&
