The article examines the tesseract, a four-dimensional hypercube, and explores various methods for rendering it on a two-dimensional screen. It discusses the mathematical concepts and visualization techniques involved in representing higher-dimensional geometry.
The article presents an algorithm that can transform aperiodic tilings that cannot be processed by finite-state transducers into ones that can. This builds on previous work about finite-state transducers for aperiodic tilings.
The article describes using algebraic field extensions to brute-force solutions to Langley's geometry problem. It presents an application of extending rational numbers to solve elementary geometry puzzles through computational methods.
