Effects of Radicals

Unless you know a bit about science, you will probably find this chapter difficult in places. A subject like this cannot be adequately covered without a few technicalities, and here I am dealing with the basic scientific facts underlying the whole matter. You might be tempted to skip some of it. But I recommend that you have a go at the whole explanation. It may not turn out to be so bad as you expect. If you do work through it, you will be able to read the rest of this book with a clearer understanding, and you will also be able to take a more critical and intelligent interest in magazine and newspaper articles on the subject.
