Killing Floor

Author: Lee Child
Amazon info

I have a theory that an author's first book is often their best and so I picked up Killing Floor by Lee Child (after a recommendation to read his books). I was not disappointed. The protagonist, Jack Reacher, is an intriguing character and relies on his role as a Military Police Officer to both solve crimes and to survive the solving of said crimes (spoiler - he plays dirty). The Jack Reacher character was the biggest appeal of this book as the plot was fairly predictable, including the somewhat interesting love interest who must be discarded from the rest of the series as Reacher is the prototypical "Ramblin' Man". There was also a nice musical subtext - but it was blues-centric and therefore lost on me.

Recommended: Fans of action/mystery, esp those who like tough guys.

The Twilight Saga

Author: Stephenie Meyer
Amazon info

This series of books is very intriguing to me - particularly in how it is likely to appeal to males/females. For males, the superhero aspects of the vampires and werewolves as well as the implicit action scenes are fascinating and compelling. However, the incessant self-doubts and "I have to leave you because I love you too much"//"No, it is I who love too much" dialogue gets very, very tiresome. For females on the other hand, I think the book is perfectly targeted at the many girls who read a lot and somehow believe that they are very average (like Bella). To have some god-like figure (Edward) see fantastic things in themselves, that they don't see, must be extremely appealing.

I found the books hard to put down, although I had to skip over some of the more repetitive dialog. It is interesting to compare the first book to the first movie. In a nutshell, I would say the book is for girls and the movie for boys (grossly generalizing of course). For example, in the final scene, the movie focuses on the big battle with James, while the book only mentions it in passing and focuses on mother/daughter relationship issues. But if the studio/author can pull off this combination (book for girls, movies for boys) they will make an absolute fortune.

Recommended: Girls that read a lot. Boys that can skim.

The Equation That Couldn't Be Solved

The Equation That Couldn't Be Solved: How Mathematical Genius Discovered the Language of Symmetry
Author: Mario Livio
Amazon info

This book covers the story of proving that, in general, quintic equations cannot be solved. Or, put another way, there is no "quintic" formula like there is a quadratic formula. The author covers a wide range of interesting topics - both historical and mathematical - and does a pretty good job with striking a balance between the true math and something that can be understood by the layperson. There are also some surprises - such as an excursion into simple groups and "the monster".

But the author's main interest appears to be Evariste Galois, the mathematical prodigy who died at age 20, but managed to invent an entire field of mathematics (Galois Theory) in order to prove that there was no general solution to the quintic. In particular, the author indulges an entire chapter on theories as to how and why Galois became involved in the duel that took his life. Not that relevant mathematically, but the book is good enough to allow the author a little leeway.

My only reservation was that I didn't seem to learn as much about various symmetries as I was hoping. I did come to a better understanding of the symmetries of cubes (and their duals, octohedrons) and I saw the connection between the symmetries of triangles and the possible permutations of three objects - but it feels like I was missing something here. Perhaps when I re-read one of the chapters to Matthew.

Recommended: If, and only if, you are interested in math.

The Last Lecture

Author: Randy Pausch
Amazon info

The story is pretty simple - well known computer scientist gets incurable cancer and delivers traditional "Last Lecture". But this time the story is reported, the video spreads, and a book is written. (I haven't seen the lecture yet). The book is the story of how Prof. Pausch prepares for death by living. It is thoughtful and insightful. I think it had less of an impact on me, since my thoughts are already so similar to the author's (and, apparently, quite different from mainstream thought). But it still gave me pause and for at least a few hours I was probably a better human being.

Recommended: To all, especially parents.

Wild Swans: Three Daughters of China

Author: Jung Chang
Amazon info

After I enjoyed "The Man on Mao's Right" a fried recommended Wild Swans. I was particularly curious as to whether this book would have similar characterizations of China's key leaders and the important events during the 50s, 60s, and 70s. In particular, was Zhou En-Lai really a hero and was Mao's wife as evil as it seems. And, at first glance, the books are quite consistent. Both show tremendous respect for the Communist Party system that emerged after the Civil War with the Nationalists - with particular emphasis on the restraint of the Communist Army and how well it treated peasants. But then in the mid-50s Mao seemed to start to become obsessed with rooting out "anti" thoughts/people. And both books describe the horrors of the "Great Leap Forward" (backyard steel production) and the "Cultural Revolution" (ignorance is good, make revolution not products).

Against this background, Wild Swans is the story of three generations of Chinese women and their travails - even given their relative privilege. Most interesting to me was the author's father who put the party rules and "the right thing" ahead of his family's needs. He was truly incorruptible and was eventually destroyed by the system he tried to serve. I also learned more about the Chinese naming system, learning about "generational names" that are used as middle names and make it easy to determine what level cousin you are (as all first cousins share the same generational name).

The only complaint that I have is with so many generations it is hard to keep track of what daughter/mother mean as the point of view changes - are we talking about the author's grandmother's daughter (that is to say, her mother). But this got easier in the last half of the book as we shift more to the author's life.

Symmetry and the Monster:

Symmetry and the Monster: The Story of One of the Greatest Quests of Mathematics
Author: Mark Ronan
Amazon info

Although I struggled with group theory as a sophomore, I always appreciated its beauty and applicability. The positive outcome of "reading" this book is that it encouraged me to go back to group theory basics and see if I can get a real understanding of normal subgroups, quotient groups, cosets, etc. This time I will do it with Matthew so that he can remember long after I have forgotten.

And speaking of forgetting, this book was somewhat forgettable. The author had a particularly annoying habit of introducing a subject only to say that we would get back to it later. Once or twice this is fine, but dozens of times - highly annoying. In addition, the author overexplains things that are obvious (for example, pointing out that integers are the positive and negative whole numbers) while under-explaining the hard stuff - like various symmetries.

Recommended: Those who have just finished a college level group theory course and who are looking for some geeky vacation reading.

An Imaginary Tale

An Imaginary Tale: The Story of "i" [the square root of minus one]
Author: Paul Nahin
Amazon info

Well, I learned two things from this book:
a. A very nice way to look at i (sqrt(-1)) is a rotation of 90 degrees counter-clockwise in the complex plane. It also makes it really easy to understand the five roots of the equation x^5-1 = 0.
b. I would be challenged taking upper level college math classes - severely challenged. But I do feel reasonably confident up through trig, although I have no recollection of integrals of trig functions.

The first three chapters are the more historical and accessible chapters and I enjoyed them. However, trying to follow real math on the Kindle was a problem, as it requires constant page forward/page backward movements - which is not the Kindle's strength.

After the first three chapters the going gets tougher (esp on the Kindle), but the author does a very good job of leading the way - and seems like he would be a wonderful math professor to have teach a class.

Recommended: Math majors and way serious math geeks who read the book on paper.

1491

1491: New Revelations of the Americas Before Columbus
Author: Charles C. Mann
Amazon info

The story of the "New World" in its pre-Columbian days - wide ranging and somewhat speculative, the book main thesis appears to be that the "New World" is much older than we may have thought previously (settled perhaps 25,000 years ago, rather than 13,000) and that the civilizations were much larger than previously estimated. An important piece of the puzzle is that smallpox and other diseases may have reduced populations by 50-75% (or more) prior to the arrival of the permanent settlers. The author theorizes that the strength of the original Native American civilizations may have been sufficient to defeat initial incursions, but having already suffered tremendous losses due to diseases, they had little chance.

Another theme that runs through the book was the degree to which the Native American peoples interacted with the land - the author's thesis being that they "manageably farmed" the land (with some notable exceptions). This may stand in contrast to some viewpoints that indigenous peoples were small groups that lived lightly on the land. And, the author highlights how various views of Native Americans are promulgated for political purposes - whether it be radical environmentalists or developers.

The scope of the book is wide and covers many civilizations in both North and South America - in fact, it might even be a little too broad. However, I may have been hindered in my understanding as the Kindle did not do a good job of displaying the many maps and diagrams.

Overall - an engaging and evocative look at pre-Columbian times in the Western Hemisphere. Written by a journalist, so it is readable, but also somewhat on the speculative side. Recommended to all - except scholars in the field.

Our First Cruise

The core details - we flew down to LA and sailed out of Long Beach port on Sunday night, April 5th. After two days at sea, we came to our first port - Puerto Vallarta, the next day it was Mazatlan, then Cabo San Lucas, and then another day at sea before returning to Long Beach on Sunday morning, April 12th. We were on Carnival Cruise Lines "Splendor" a new boat making her first trip to the "Mexican Riviera".

Here we are lounging on the deck before getting underway. You can tell this is the beginning of the trip because of how pale we are. However, due to extensive use of sun screen, we looked pretty much the same at the end of the trip as well.

The Splendor is a very impressive ship - 12 decks, 300' long, holding over 3500 guests and 1000 crew. It has many restaurants, pools, Jacuzzis, an extensive gym, spa, and casino - and many many places that I am sure we never found. Here is a picture of their theatre, used for nightly shows and informational meetings. It occupies three decks near the front of the ship.

The first two days of sailing were calm. The kids checked out their respective "camps" - Matthew's was somewhat better planned than Emily's so he spent a little more time at his camp. Emily got to relax and read. At night the crew provided animal sculptures made out of towels.

Our initial stop was at Puerto Vallarta where Molly and the kids embarked on a series of zip lines through the canopy.

We also checked out the beach in Puerto Vallarta, where some impressive sand sculptures are done.

At our next stop in Mazatlan, it was time for horseback riding along the beach. This required a tram from the cruise ship to the main terminal, a bus to the dock, a boat to the island, and then the "Stone Island Limo" to the horses. The "limo" is more accurately described as a bunch of benches attached to a tractor. But it sure was more comfortable than riding the horses - but that was mostly due to our lack of skill at horseback riding. The horses were responsive and Emily even got hers into a gallop. Of course, we were all sore for varying amounts of time afterwards.

This was followed by some additional beach time.

Our final stop in Cabo San Lucas was mostly for shopping - as we were too sore for anything else. We stopped at one store that sold items that changed color in the sunlight (UV sensitive elements are embedded into the weave) - it is a really cool effect - now let's just hope it still works after the laundry. Along the pier, the kids allowed an iguana to perch on their heads - although I am not quite sure why.

From there, we passed by the famous "Los Archos" at the very bottom of Baja California

and began our journey home. The seas were rough on the final day - or at least rough enough to close the swimming pools. Emily and I felt a little nauseous and it was very strange to be working out on the elliptical as the ship moved back and forth. But no meals were missed and we managed to take a few pictures of the room - which had balconies that afforded wonderful views.

Some random final thoughts.....

The most amazing thing about the cruise is really the ship - the magnitude and complexity are staggering - considering that this thing is moving 20 miles per hour 24 hours per day. It is hard for me to get lost and I found myself completely bewildered for the first two days, never quite sure which direction was which. The food was very good, highly varied, and unending. It is NOT a good place for a diet. Our waiters were continually surprised that we ordered only one appetizer and one entree - each. Apparently people eat multiples. However, the ship was very crowded (perhaps because it was Spring Break) and the trips to Mexico were as authentic as Pier 39 is to folks visiting San Francisco (Pier 39 is, by the way, the place to which cruise ship visitors to SF undoubtedly head) - the NY equivalent is probably the Empire State Building.

Library Books on Kindle

I have been waiting YEARS for this capability and as of today, it is a reality.

Here are the steps....
1. The key software is called KindleFix, it is available at http://igorsk.blogspot.com/2007/12/mobipocket-books-on-kindle.html
2. Before you can use this software, you need to install Python. I found good instructions at http://www.richarddooling.com/index.php/2006/03/14/python-on-xp-7-minutes-to-hello-world/
3. Now with Python installed, you can run the first script which requires your Kindle Serial Number (back of Kindle) and gives you a MOBI PID
4. Now it was off to the Northern California Digital Library - http://califa.lib.overdrive.com/
5. Downloaded a book in mobi format (a prc file)
6. Back to Python to run the second script - which takes the path to the dowloaded .prc and the MOBI PID generated in step 3 and generates a .azw file
7. Plug in the Kindle via USB, copy the .azw file.
8. Unplug Kindle, go Home, start reading
