Inspiring and empowering quotations

Payn captures the art in the business of consulting.I will end with my favorite:
Consultants be forewarned: You cannot manage CHANGE, it manages you. Respond and anticipate its flow. RULE 211
Happy reading!
A wonderfully fun and enlightening book.In respect to technology and where we as professionals stand, Mr Payn is right when he says that "we are already behind." In my practice as an Internet Technology Consultant, I find that more time is spent on keeping abreast of new technologies in order to better help my clients keep up with their customers. Many of the passages in the "Consultant's Advanced Instruction Book - 303 Rules to Guide Consultants in the Internet Age" helped to remind me of lessons long since learned and forgotten, as well as inspired many "ah-ha's" that were truly needed. This book is inspiring, witty and intelligent. At the same time it provokes thought and embodies the spirit of what we as professionals do, advise to the best of our ability.


What a time -- well remembered.
Love advertising as art? Okay, how about as humor?These are his stories. They're all funny. Many of them also reveal truths of ad agency life, the kinds of people attracted to that business, and the thinking that goes into a great campaign.
Welch had art-director friends each design a separate chapter, and told them to go wild. The designs are readable -- these are top-level art directors we're talking about -- and range from whimsical to surprising. Not a bad thing in a book of stories.
The book reads the way I remember that era. Except Welch obviously had a lot more fun.


How stars work
The biggest explosionsWheeler begins his book by describing how stars form, how they evolve in response to gravity, how they ignite, how they burn, and eventually how they die. This is a logical introduction, since virtually all the examples of cosmic catastrophes involve stars in one form or another. Like people, though, the life of each star is unique - and the end times are very different. Wheeler does an excellent job of describing the negative feedback process that stabilizes solar activity. If the star generates too much heat it expands. This expansion reduces the temperature, and throttles back on the rate of nuclear fusion. If the star cools down it contracts, and the contraction heats it up again, keeping the rate of fusion at a remarkably constant level for long periods of time during the stars life.
Much of Wheeler's text is actually about how stars evolve. This is important because to understand their deaths, you need to understand how they are born and how they evolve over their lifetimes. Their deaths are frequently the most interesting parts of the story because they are often involved with the catastrophes that are the book's principal thesis. While I bought the book because of its discussion about cosmic catastrophes, I found it valuable for its descriptions of stellar evolution alone. This includes a nice description of the "solar-neutrino" problem as well as a nice explanation of the red-giant phase, and especially the last stages during the life of a massive star that explodes in a super nova.
The foundational understanding of the basics of stellar evolution makes it easier to follower Wheeler as he takes the reader on a tour of the major players in cosmic catastrophes: white dwarfs, super novae (of many different types), neutron stars, black holes, and gamma-ray bursts. Wheeler's descriptions of these phenomena (to the extent that modern science understands them) are among the best I've seen in a popular science textbook. There is also a smattering of discussion about the origin of the universe in the Big Bang, and some interesting speculation about time (and space) travel using black holes.
In any book dealing with modern cosmology and astronomy there are inevitable discussions about the nature of space and time and how they fit together with Einstein's theory of general relativity. Most such books have at least one figure showing a funnel-shaped construct with grid lines converging as they swoop into the tapering end where the black hole resides. Wheeler uses lots of such diagrams. However, I think he does a better job than most at helping the reader understand what the diagrams illustrate. More importantly, he helps the reader understand what the diagrams do not illustrate, and their limitations (he dispels some common misperceptions about these sorts of figures). I especially enjoyed Wheeler's explanations about how one might (with the application of the appropriate mental acrobatics) use the diagrams to actually envision what is really going on in our multi-dimensional world.
Another thing I liked about Wheeler's book is the clear and frequent illustrations. For the most part the author has anticipated those places where prose just cannot quite complete the mental picture. When this happens there is inevitably a well-constructed diagram that finishes the concept and makes things clear. There was one exception, however. Figure 7.3 really needs to have an arrow or circle marking the location of SN 1987A. [I'm pretty sure I found it, but the exposure changes between the photographs, and so I'm not quite sure. It would have been nice to have the author's help in preventing a false identification.]
Reading this book one gets the sense that even though it is a qualitative description of astronomy (there are no equations) Wheeler is not over simplifying. His discussion of super novae, for example, lists many classes and describes theoretical uncertainties that other authors gloss over or ignore all together. Of course there is much more detail to super novae than what is in Wheeler's book. But at the qualitative level Wheeler leaves the reader understanding that there are many classifications of super novae, that some of the boundaries between classifications are not always so clear cut, and that we still don't know a lot about how some types form, and how other types explode. These are concepts that other popular science textbooks don't always convey. I think the only thing missing from the chapters on super novae is a table that summarizes all the different types and some of their descriptive identifiers.
Unlike some popular science texts, Wheeler devotes quite a bit of time describing the evolution of binary stars, which play an important role in some of the greatest cosmic catastrophes. I think he does an especially good job of qualitatively describing accretion disks, and how they fit in the context of mass transfer in binary systems. It's this mass transfer that is ultimately involved in some of the most spectacular catastrophes in the sky.
Overall, this is a great book. If you enjoy astronomy I'm sure you will find it satisfying and informative. It's just the sort of book to enjoy on a vacation, or after a grueling day at the office.


Vindication for Wetherills
Detective story on finding "lost" archaeological collection

Useful tool for all dealing with structure determinationThis gap has been filled by Massa's book.
It focuses - unlike other crystallography books - on the practical applications and enables the reader to attack own structural problems by himself. Additionally, this book will provide the necessary theoretical background to understand how X-ray diffraction works, how crystals are built, all this symmetry stuff and so on.
The absolute highlight is, however, the step-by-step explanation of a structure determination, where one can almost see the author sitting in front of his computer and struggling with one of his structures, explaining every step in detail.
Crystallography still needs heavy brain work sometimes. But this book won't cause unnecessary headaches as many other crystallography books do.
Therefore, I recommend this book warmly to my crystallography students.

Uncle RayWhen I was a child Aunt Ackey use to go through her old photo's of ray and tell us the stories.
Ackey recentley passed away earlier this year in her 90's and every one should know what a pistol she was. Thank you Russ and Bev for the wonderful job. Jim
