Errata discoveries

Being a realistic technologist, I expect errors - typos and even the technical variety - in my book. It would help if you can send me an e-mail so that I can make the necessary corrections in future reprints. Useful and constructive comments will be acknowledged in future editions. Expensive chocolate, fine wines, and generous praise are also welcome. You can find the latest erratum list at www.mokhengngee.per.sg/book.
