Applied Geometric Algebra
László Tisza · Massachusetts Institute of Technology
The mathematical tools employed by physicists have expanded considerably, from differential calculus, vector algebra and geometry, to advanced linear algebra, tensors, Hilbert space, spinors, Group theory and many others. These course notes attempt at bringing conceptual clarity and unity to the application and interpretation of these advanced mathematical tools. In particular, there is an emphasis on the unifying role that Group theory plays in classical, relativistic, and quantum physics.

Core Agricultural Economic Principles
Jason Bergtold · Kansas State University
This page introduces essential economic concepts, including opportunity costs, which highlight benefits lost when selecting one option over another. It delves into marginal analysis concerning incremental benefits and costs, and discusses elasticity, detailing the responsiveness of demand or supply to price changes. Additionally, the implications of prohibition on supply and demand dynamics are examined. Collectively, these topics form a foundation for understanding economic decision-making.

Phylogenetic Comparative Methods
Luke Harmon · University of Idaho
Evolution is happening all around us. In many cases – lately, due to technological advances in molecular biology – scientists can now describe the evolutionary process in exquisite detail. We understand the genetics, development, and biomechanical processes that link changes in a Galapagos finches’ diet to the shape of their bill. And, in some cases, we can watch as one species splits to become two.
