## Requirements

• High school algebra
• Part I of this course

## Description

This course is about algebraic structures. It includes an introduction to identity, inverse and idempotent elements. We'll see that Boolean conjunction and disjunction can be seen as multiplication and addition and investigate possible additive and multiplicative identities and inverses. This is followed by power sets and basic operations on elements of power sets (union, intersection, complement, difference). All concepts are then combined in a discussion of algebraic structures including groups, rings and fields. We end with Boolean rings and describe set algebra as an example Boolean ring. In the review session we complete an example proof from CH1 of W. Rudin's Principles Of Mathematical Analysis using the axioms of a field.

My passion for applied math and data science stems from my study of computational chemistry. Although I don't believe you need a degree to learn any subject I did complete a PhD at UT Austin. Our research group studied biophysics with statistical mechanics and molecular dynamics simulations. My graduate studies included completing all math course requirements for a MS in applied mathematics qualifying me to teach both math and chemistry at university level. I have 4 years of university teaching experience. After graduating I did a postdoctoral fellowship in a robotics group in the computer science department at UNM. I decided to go into industry and I am currently a senior data scientist at a Fortune 15 company
