Science Notes by Barry Gray Main Index

Science Pages

These Pages provide information about a single topic, or sometimes a group of related topics. They are intended to explain the ideas involved simply but also help you to understand how they fit into the real world.

Each Page is designed to be read through in order, as each Section builds on the Sections before, but for most longer Pages it is possible to go straight to a particular Section. On most Pages there are links to other Pages in my own Web Site or to other people’s Web Sites, but I suggest that you do not use them the first time you visit any Page on my Site, unless you need to do so in order to understand the Page, as you can easily lose the thread. You can always tell whether the Page you are looking at is one of mine or someone else’s because I do not think anyone else is writing on Ancient Egyptian papyrus.
