This is a worksheet on Fermi Problems that I created back in 2005.

My Stuff is where I put resources that have nothing to do with maths and/or nothing to do with digital resources and/or nothing to do with interactivity.

It is just a handy location for putting files on the web that I want to share.

The attached file is my bible on database Normalisation. I can't remember where I got it from, but probably from someone on the qsite-ipt list. Please advise if you know the source.
