Pure mathematics is a branch of mathematics that is concerned with abstract concepts and theoretical frameworks, rather than applied mathematics which focuses on practical applications and problem-solving in real-world situations. It seeks to explore mathematical ideas for their own sake, often leading to the development of new theories or the discovery of relationships within mathematics itself.

"Works by Archimedes" refers to the collection of mathematical and scientific writings attributed to the ancient Greek mathematician and engineer Archimedes of Syracuse, who lived from approximately 287 to 212 BC. Archimedes is renowned for his contributions to mathematics, particularly in geometry, calculus, and the understanding of the principles of leverage, buoyancy, and hydrostatics.

"Planisphaerium" typically refers to a type of celestial map or star chart that presents a two-dimensional representation of the night sky. The term can also relate to specific tools or devices used for celestial navigation, such as star globes or planispheric astrolabes.
