About. Absorb Mathematics Absorb Mathematics is an interactive course written by Kadie Armstrong, a mathematician and an expert in developing interactive online content.

It offers a huge amount of interactivity - ranging from simple animations that show hidden concepts, to powerful models that allow flexible experimentation. Absorb Mathematics is divided into units – roughly corresponding to a lesson – so you can follow the structure of the course all the way through or use the units individually when covering a particular topic or concept. Each unit provides an engaging narrative supported by interactive animations, our unique simulations and exercises to ensure concepts have been understood. Try the free sample units in your class.

Throughout the years as an engineer, I have needed to research topics on engineering, physics, chemistry, mechanics, mathematics, etc.

The Internet has made the job infinitely simpler, with the caveat that you have to be careful of your sources. Anyone can post anything on the Internet without peer review, and errors are rampant. The topics listed below are primarily ones that I have researched and generated custom pages for the content. I welcome visitor review and comments on my material to help ensure accuracy.
