Mary-Kate is having a hard time. She is being accused of a thief. A mystery but this time Olsen hired Olsen!

Senator takes us back to a simpler time with clearer values. This first work reminds many of us about a culture we thought was so embarrassing at the time, but now would love the opportunity to return. Told through the eyes of young Brooklyn boy enjoying his summer vacations in the Catskills, this is a fun and quick read. You will feel better for having read it.

Great book. I finally have found this book after a long search on outdoor activities. Very interesting hints on what high rope exercise are and how to debrief them. I'm reading again and again finding alwais new sources of ispiration. Unfortunatly many photography are impossible to be understood.

I like the way this book opened with a suspenseful sequence, giving you just enough information to hook you but not enough to give anything away. I didn't figure out how it was going to end until the end, but enjoyed the clues. The author develops each character , when the story permits. She does a good job with all ages of characters, from teenager to elderly. The description of the surrounding country side was perfect. I have visited Millbrook both this summer and last and found myself picturing some of the farms as the author described the locations of each scene. Buy this, read it, good night time reading , not too scarey for before bed but you might find yourself staying up later than you expected to. I found myself trying to read and eat lunch in a restaurant while reading this book and I did let my food get cold.

This book, a compilation of 33 articles covering many different aspects and applications of Clifford algebras, can be read profitably by anyone desiring an overview of their history, theory, and applications. I did not read every article, and space also prohibits such a comprehensive review, so I will comment only on the ones that I actually studied.

Chapter introduces Clifford algebras as an extension of the real numbers to include vectors and vector products. The familiar representation in Euclidean space is outlined, with emphasis on the exterior product of two vectors, which, the author points out, is associative (unlike the ordinary cross product). The connection with rotations, reflections, and volume elements is pointed out, and the complex numbers and the Pauli algebra are shown to be Clifford algebras.

A short history of Clifford algebras is given in chapter 2. The reader not familiar with Clifford algebras should have no trouble following the ensuing discussion where some elementary geometric constructions are given of the Clifford algebra on the Euclidean plane. In addition, the operator approach to Weyl, Majorana, and Dirac operators is given, illustrating in detail their connection to physics. Recognizing that the Fierz identities do not by themselves give the Weyl and Majorana spinors, the author introduces what he calls the boomerang method for their construction. The boomerang is essentially a linear combination of bilinear covariants for a spinor, and the author details the conditions under which the spinor can be reconstructed. Interestingly, and unknown to me at the time of reading this chapter, the author constructs a new class of spinors, the "flag-dipole" spinors, that are different from the Weyl, Majorana, and Dirac spinors.

The author of chapter 3 considers the construction of Clifford algebras from a more geometric viewpoint, calling them geometric algebras, which he motivates by the consideration of extending the reals by a unipotent ( a number not equal to +1 or -1 but whose square is 1). The resulting unipodal numbers are isomorphic to the diagonal 2 x 2 matrices. The extension of the unipodal numbers so as to make this isomorphism to the full 2 x 2 matrix algebra leads to Clifford algebras.

In Chapter 9, the spacetime algebra is brought in to study electron physics. The "space-time algebra" or STA is used to characterize the observables associated with Pauli and Dirac spinors. The material presented is standard in physics, wherein the Green's function (propagator) for the Dirac equation is given, along with scattering theory. The typical problem of scattering off a potential barrier of finite width is discussed, along with the Klein paradox.

The space-time algebra is also discussed in the context of the interpretation of quantum mechanics in Chapter 11. The authors really do not add anything new here (in terms of what one might consider "strange" behavior in quantum physics). They interpret Dirac currents as measurable quantities, avoiding seemingly any notion of wave packet collapse and difficulties with defining tunneling time(s), but not answering at all how to measure these currents. In addition, the Pauli principle is interepreted in the context of space-time algebra, without any quantum field theory. Howerver, it is not shown that such an approach satisfies cluster decomposition, casting suspicion on its utility.

In Chapters 21, 22, and 23 the author shows how spinors fit into the framework of the Lorentz group, their relationship to the Clifford algebra, and in general relativity. It is shown how the Dirac spinor can be defined in three different ways, namely as an element of the representation space of the Clifford algebra of spacetime, an element of the representation space of the fundamental representation of the Dirac spinor metric-preserving automorphism group of the Clifford algebra, and as an element of the representation space of the fundamental representation of the covering group of the conformal group.

The most interesting discussion in the book is chapter 28 on extending the Grassmann algebra. Dispensing with any scalar product on a vector space, the author shows how to obtain the relative magnitude between two vectors and this leads to the notion of a multivector. The duals to these are called outer forms, and are the familiar differential forms when depending on spatial position. Many helpful diagrams are used to illustrate the properties of multivectors and pseudomultivectors, the linear span of which is called the extended Grassmann algebra of multivectors. Adding a scalar product reduces the number of directed quantities to four, and electrodynamics can be formulated in a way that is independent of the scalar product.

A lot of poultrykeepers feel the temptation to invent their own chicken feed blend. Doing this successfully requires quite a bit of knowlege, and this book provides it. It's quite accessible to the interested layman, though it assumes you already know something about nutrition (for example, it doesn't explain what amino acids are or why you'd care).

Not as exhaustive as Ewing's massive and long-out-of-print POULTRY NUTRITION, but it's more up-to-date and far easier to use.

I enjoy reading books to my eight year old. I also like to get or see the expressions on her face. This book is an easy reader for her and she enjoys fantasy stories. She like to make up her own.

I recommend this book to parents who like to read to their kids/kids that are in second grade and are on the Book It Club.

This book made her talk about it to her teacher and classmates and gave them ideas for a school project.

This book brings back pleasant memories of leaky cabins, alien counselors, fun craft activites (beaded wallets, beaded key chains, beaded belts, beaded belted dust kitties) and food that defies description. For every child who attened camp, this book is a must read. We've been reading it in my family for 15 years, and it still cracks us up - probably because it's all true!

I recently tried two recipes for a chocolate banana cake and Maple Candy Corn [similar to Poppycock snack]. Both were easy to make and came out wonderfully. The recipes are clear and easy to follow, photos mouthwatering.

Roger & Susie have made cruising to the Bahamas look easy and simple. This book has paid special attention to every detail and is well worth the few bucks it cost.

If you are planning this type of a cruise or just read about their adventures it worth every penny and more. Maybe we should send Roger & Susie some money for writing the book too!
