Agenda. This web site is dedicated to perfecting a universal mathematical language for science, extending its applications and promoting it throughout the scientific community. It advocates a universal scientific language grounded in an integrated Geometric and Inferential Calculus.

Geometric Calculus is a mathematical language for expressing and elaborating geometric concepts. Spacetime algebra is an application of this language to model physical space and time. It is the core of a universal language for physics, providing invariant formulations of basic equations and a powerful computational engine for deducing their consequences.

Inferential Calculus integrates deductive and statistical inference into a coherent system for matching scientific models to empirical data. It provides a unified framework for data analysis, image/signaling processing and hypothesis testing from incomplete data. Thus, it supports the semantic bridge between theoretical constructs and empirical realities.

Modeling. Scientists make sense of the real world by constructing models to represent the structure of things and processes within it. Geometric Calculus provides a rich language for the construction and analysis of mathematical models. Inferential Calculus provides a framework for their empirical validation.

This site is devoted primarily to the development of Geometric Calculus with many applications to modeling in physics, mostly the work of David Hestenes. A companion web site on Geometric Algebra is at the Cavendish Laboratory, University of Cambridge. Inferential Calculus and Modeling are treated in greater depth at other sites.
