On my vacation in May I had time to read another book I would like to recommend. It is "Verborgene Universen. Eine Reise in den extradimensionalen Raum"
from Lisa Randall (ISBN: 3100628055), the english original is named "Warped Passages. Unraveling the Mysteries of the Universe's Hidden Dimensions"
This book is a must have
if you are interested in physics.
Another book I read was "Lotus Notes Developers's toolbox. Tips for Rapid and Successful Deployment"
from Mark Elliott (ISBN: 0132214482
). Mark Elliott starts by explaining the basics for Notes/Domino Developers: DesignElements, Formula and LotusScript. If you are new to developing web-applications with Domino you will find a chapter focused on that area (reserved $$-fields, WebQuery-agents, ...). The second part of the book is a collection of projects you may face in real world plus, showing how to solve these problems with Notes.
