math review

It had been years since I last factored a polynomial. I had forgotten how to derive the quadratic formula. Clearly it was time for a math review. I picked up Precalculus Mathematics in a Nutshell from the Boulder Labs Library; it was just what I needed. The book by George F. Simmons zips through geometry, algebra, and trigonometry in about a hundred pages of amazingly complete and readable prose. Each section is independent of the others, so it is perfect for a quick review of any of the three topics alone. The book is sparsely populated with exercises, just enough to get a solid grasp of each topic. The exercises, as in any good math book, reveal insights beyond those illustrated in the text. I can't imagine a better tool for review, but the book probably wouldn't serve well as a first introduction to the subjects (except perhaps in the hands of the right teacher).

a good book

Yukio Matsuo's Ice Sculpture is a marvelous book, really two books in one. The first is filled with full-color photographs of the master's work, ranging from traditional culinary pieces to original abstract sculptures. Many of them demonstrate the sculptor's distinctive style. The second is a series of sketches, diagrams, and notes that concisely illustrate how to carve each of the depicted pieces. Wonderful!

What do you get when you pair architects with minimalist artists and turn them loose on media (snow and ice) they have little or no experience with? The Snow Show is a book filled with wonderful, full-color photographs of the results, creations that are beautiful and interesting enough to more than make up for being somewhat monotonous. Unfortunately, the book also features page after page of uppity, dysfunctional prose. Even the show's web site, with its "this experience is more important than anything else you could possibly be doing" full-screen presentation, manages to express the worst along with the best of the. . . Okay, I should stop now. Get this book for your coffee table and leave it there.

Snow Sculpture and Ice Carving is about as contrasting a book on the subject as could be imagined. A product of 1970's craft culture, James Haskins's book features black and white photos of sculptures that are more accessible if a bit crude. I didn't find the book terribly interesting, however, as it is heavy on ideas for what to carve but light on technique.

I picked up Ice Carving Made Easy, Practical Ice Carving, and Ice Sculpting the Modern Way from the local library. I have finished the first two but am still working my way through the third. So far, I haven't encountered very many insights that I hadn't figured out already, but a few tidbits have stood out.

Ice Carving Made Easy contained a couple of interesting points. One was the description of steam cutting in chapter three. Both Lars and I have been experimenting recently with cutting ice by bringing it in contact with metal tubing carrying hot fluids. According to the book, using steam in this manner is "still preferred by some carvers accustomed to older techniques" despite its slowness.

Chapter One, The History of Ice Carving, of the book includes some interesting details of the ice palace commissioned by Empress Anna Ivanovna in 1739.

"Inside, every detail was carved from ice. The highlight was a translucent clock with all of its interior mechanisms detailed, displayed on an ice table in the middle of the drawing room."

Could it have been a working clock? Considering that the palace was built some years after the invention of the Deadbeat Escapement, I think that it is possible. A clock of the size Lars and I hope to build would have been difficult with the technology of the time, as would a very small clock, but a table-top model would have been the most likely to succeed. Lending credence to the idea is the account of various other functional artifacts of ice:

"Six statues and an elaborate frontispiece graced the front entrance; two dolphins and one life-sized elephant fountain sprayed water 24 feet into the air. Two mortars and six cannons fashioned of ice were working replicas; they fired frequently. An ice-log bathhouse, also functional and used on occasion, completed the grounds."
