Multiple 'rithms

At breakfast this morning I was discussing abucuses (abaci?) with my mother and father. We weren't really sure how they worked or how you did hard sums on them, but I was fairly sure that I had known this when I was younger and that there were various algorithms that could be used to do different kinds of sums (ie hard ones like long division). This confused my parents at first as they didn't know what algorithms were and had confused them with logarithms.

Whilst the two words do seem to be anagrams of one another, they do not mean the same thing and after I'd explained what an algorithm was we talked about logarithms instead (isn't breakfast exciting in my family?).

I told mother that we don't really use log tables any more because of the calculators and computers that we now have. She got a bit worried about the implications of this reliance on technology should Islamic terrorists wipe out all our computers or the internet or something - how would we do logarithms then if we'd all thrown our tables away?

I pointed out that should that happen, doing logarithms would be the least of our problems as society would likely start to fall apart and we'd all have to run to the hills with our guns and our cans of beans. She thought that should such an attack happen then she would go to work as normal and just try and carry on. This was a little odd since she is retired and I'm almost certainly sure her work never once required her to use a logarithm, but I suppose she was speaking hypothetically. Maybe if she did go to work as normal we could all phone her up from the hills every time we needed a logarithm doing. I guesss it would keep her out of trouble.

I used to know a joke about log tables.

After this excitement I went to do my final pre-Christmas Christmas Shopping. This was also exicting as I was not in Kansas (York) anymore.
