## Why this blog?

**Background**

I enjoy learning and maths has always fascinated me once I got over typical school boy dislike. I know I am not a proper mathematician but know enough to understand most of maths if I put my mind to it and to appreciate its beauty, similar to appreciating a good book even though I am not capable of writing one myself.

I studied maths to A-level as two subjects, Pure Maths and Applied Maths and of course it featured a lot in my graduate Physics course.

**General Relativity**

Every autumn I prepare for winter activities and most recent years I have decided that this is the year I am going to get to grips with General Relativity. Special Relativity I can handle but the university steered away from attempting to teach General Theory. This usually makes me realise that I should at first refresh my maths knowledge, and this is what I am starting out on, again, just now. This winter I shall be 70, so if I am ever going to achieve this I had better get a move on.

**Note Taking**

I prefer to make notes on line and store in the cloud so that I can always access them when the mood takes me. I am these days completely Apple hardware, iMac, MacBook, iPad and iPhone. My wife has iPad and iPhone. My daughter's family also are Apple dominated, with just a few old windows lap-tops that see the light of day occasionally for grandchildren homework, but this is less as they now can use Mum's MacBook (hand down from Dad).

Documenting maths has caused me some concern. What is the best way to write equations which are easy to do, can be edited and look good. I believe I now have the solution which will be the subject of another blog entry.

**Reason for Blog**

So primary reason for this blog is so I can jot down my maths notes as they arise, which I can then, if desirable, organise into a more formal web site later.
