Mind Expanding


In his book Science and Sanity, in explaining his great formulations of _abstracting_ and _consciousness of abstracting_, Alfred Korzybski coined three fundamental truths about human knowledge and understanding: (1)The map is not the territory, (2) the map does not show all of the territory, and (3) the map is self-reflexive. It is this last truth, the map is self-reflexive, which interests Douglas Hofstader, and he does a wonderful job of exploring it in all its richness, using the works of Godel, Escher, and Bach as a theme or jumping-off point, on to modern mathematics and beyond. He says, "I remember at an early age, there was nothing more fascinating to me than the idea of taking three 3's: operating upon 3 with itself! I was sure that this idea was so subtle that it was inconceivable to anyone else--but I dared ask my mother one day how big it was anyway, and she answered "Nine"."
Reading and working with this book is like getting a college education on the cheap, a wonderful introduction to a variety of fascinating and enlightening subjects whose substance is only vaguely understood (if at all) by the average individual. It will clear these up for you quite nicely.

Title: Intermediate Robot Building
Publisher: Apress

Wow! Lots of details. A great book.


This book is wonderfully different from most robot books in that it doesn't skim through assembly instructions on half a dozen scrap robots that the author thinks you want to imitate. Instead, this author seems to understand that I want to build my own unique robot, so his book concentrates on building tips, electrical modules, and what-to-look-for in certain parts.
For example, the infrared obstacle and wall detector in chapters 11 and 12 is standalone, has complete schematics and part numbers, and is covered in such great detail that it's going to be easy for me to incorporate it into any of my robot ideas. There are plenty of examples of robot power supplies and motor drivers as well.
If you want pretty pictures and brief descriptions of various robots to get your creative juices flowing, surf the internet. But if you want complete details on how to actually build something, get this book!

Title: The Art of Computer Systems Performance Analysis : Techniques for Experimental Design, Measurement, Simulation, and Modeling
Publisher: Wiley
Authors: R. K. Jain
Rating: 5/5
Customer opinion - 5 stars out of 5
This is the most impressive book on performance that I own.


This book is the most impressive performance assessment, modeling and simulation text I have read. It is a perfect balance of systems analysis and the necessary mathematical foundations that are extremely important to fully understand the disciplines Jain covers in this text. I have used this book numerous times for capacity planning projects, simulation studies, statistical analysis and for a guide in delivering presentations and writing papers.
