My name is Alan Grace. I live in Titirangi (Auckland, New Zealand).

Welcome to my COVID Odyssey.

For definitions and values for what I call r ( a daily increase) please see:


There are many methods that can be used to model COVID-19. You can find some in this post:

COVID-19: Methods of Analysis

In my own undergraduate and postgraduate study I enrolled in papers in numerical analysis and differential equations.

Instead I now tend to use simple maths to look at actual case data.

Titirangi is known for its bush, beaches, and Titirangi village.

This is my second blog. Posts from my first blog are also included here. Material from my first blog may also appear in new posts.

Please read the Disclaimer.

This is an example of an about page. Unlike posts, pages are better suited for more timeless content that you want to be easily accessible, like your About or Contact information.

Click here to see all posts in chronological order (This no longer works for the current theme).
This was previously recommended early when I started my blog the first time you visit with oldest first; otherwise apart from this post, all other posts will have the most recent post at the top); or start a new post (Alan only).

Click here if you want to go back to reverse chronological order
