Cantor is a software application that provides a mathematical interface for various mathematical computation backends. It is part of the KDE project and is designed for educational purposes, allowing users to perform calculations, create plots, and visualize mathematical concepts. Cantor integrates with several backends, such as Maxima, SageMath, R, Octave, and others, enabling users to switch between different systems for computation, all within a unified interface.

Lean is a proof assistant and a functional programming language developed primarily for formalizing mathematical theories and verifying the correctness of mathematical proofs. It was created by Leonardo de Moura and is used in both academia and industry for formal verification tasks. Key features of Lean include: 1. **Formal Language**: Lean provides a formal language in which users can write definitions, theorems, and proofs. This language is based on dependent type theory, enabling rich and expressive formulations.

Reciprocal length typically refers to the reciprocal of a physical length measurement. In general terms, the reciprocal of a quantity is defined as 1 divided by that quantity.
