The book has now been updated using Adobe publishing software. It was originally put together using Microsoft Word, which is not suited well to producing a book.
As a result the diagrams are now a higher resolution and clarity.
Some editorial errors and minor calculation errors, some of which have been pointed out by kind readers, have been revised.
Last, but not least, a new chapter has been added (2.13 Foundations).
Roll Out….print to order…..
The book is printed to order. Which means that when the buyer orders from the mainstream online sources (e.g. Amazon/Goodreads) – and not a ‘reseller’ – the latest edition should be available.
A label (see above) has been added to the back cover which will clearly identify the 4th edition. Any potential buyer should be able to check with any seller with a hard copy if they have the latest edition.
