This is the first post on my blog! Hurrah! Yippee!
This is not a blog which will be updated regularly. It will not be very well written and will be quite poor grammar (you see). It won't be very interesting and there won't be anything on here that you won't have heard before!
Hopefully it will be clear, sensible and reasonable though; hopefully it will clear my head! There is quite a fog in there at the moment. I intend to write about things which are obvious - why?
Well, things are obvious when you know them. It's obvious to me that there is such a thing as gravity and that it pulls things downwards. It's obvious to you, and all educated people. But to uneducated people it is still just as obvious - but they don't realise it is obvious. As far as they're concerned it is just something else to take for granted. And that is fine. But there is a reason for things falling down, not just because they do because it's in their nature, but that they do because gravity exists and the earth has a large gravitational field. So when I write about obvious things, I'm doing it because you only realise things are obvious once they have been pointed out.
Magic tricks are obvious to the trickster and to those in the know. To everyone else they're magic.
