On August 21 2017 a total solar eclipse will be visible across North America. Here are links to some of the best resources to explain why a solar eclipse occurs. From the why will flow the where and when.
If you were OK at school mathematics, but did not study a STEM subject at university, you may be interested in these resources. They are designed to help students prepare for a university mathematics admission test. They take a broader approach to understanding and problem solving in mathematics than the school curriculum.
“GeoGebra is dynamic mathematics software for all levels of education that brings together geometry, algebra, spreadsheets, graphing, statistics and calculus”.
Open source. Works online, on the desktop, and as an app.
This software is useful for creating your own objects to achieve a better understanding of mathematical concepts.
Example: Coordinate Geometry
Professor Daniel Kleitman, Emeritus Professor of Applied Mathematics at MIT
From Chapter 1 What is Calculus and Why do we Study it? “Calculus is the study of how things change. It provides a framework for modeling systems in which there is change, and a way to deduce the predictions of such models…It provides a way for us to construct relatively simple quantitative models of change, and to deduce their consequences.”
As an educated non-scientist, one of the problems in learning is that you do not have access to experiments. This is a series of 60 physics demonstration videos produced by the MIT Department of Physics Technical Services Group.
Here is an example: The Coriolis Effect. The Coriolis effect is important to understand because it is a “fictitious” force. It illustrates the concept of non- inertial rotating frames. The video also shows how easily and quickly we can understand complex topics when we see them in action.
