Science and Mathematics

The topics I cover in science and mathamatics is often related to topics I have stuggled with understanding in the past or wanted to find a way to teach my children. I try to write stuff that is very beginner friendly. Laying out all the individual steps and not assume too much prior knowledge.

## Mathematics

Why Does the Number 12 Occur so Frequently?. Reflections on the number 12 and why so many things are divided into 12 such as the clock, egg packages, a foot, pennies in a shilling.

Teaching Kids About Alternative Number Bases. This article is about helping children really understand how numbrs works. Specifically this deals with the dozenal number system. An alterantive to the decimal number system.

## Geometry

- Software for Teaching Geometry. Using GeoGebra for what we call constructive geometry. This is learning about how 90 degree angles, special triangles, shorters lines and so on can be made with a compass and ruler.
- Geometry for Navigation. How angles can be measured and used together with understanding of geometry to perform navigation. We look at how things like triangulation works, used by GPS positioning system.

## Physics

- Understanding Gyroscopes Starting from scratch explaining all the match and physics concepts you need to understand to grasp the behavior of Gyroscopes.
