Christie, Agatha, The Clocks, HarperCollins Publishers Canada 1988 Amazon costomer review: 'The first time I read this novel, I had to reread it again. Why? So many questions still linger at the end of the story even though the pages has ended. I wondered and reread and after the third reading, I finally got it all. The Clocks is a story that has two main plots, and the one has absolutely nothing to do with the other. But they were connected in a way when a young typist finds a dead body in a livingroom of a blind woman. From there it's red herring all the way. But bits of real clues emerge when Mr Lamb (a fake name) talks to a girl with a broken leg. Poirot only comes in now and then but became more interested when another murder occurs, while Lamb becomes Poirot's legs, ears and eyes. Oh yes, there are clues aplenty, but a broken high heel has never been this important as a clue. Christie delivers this story with delightful take that neither too wordy nor too lengthy. This is another often neglected classic Christie, so get it. madonluv

le Guin, Ursula, The Wizard of Earthsea (Earthsea Trilogy, Part 1), Atheneum 1990 Amazon Editorial Review: 'Often compared to Tolkien's Middle-earth or Lewis's Narnia, Ursula K. Le Guin's Earthsea is a stunning fantasy world that grabs quickly at our hearts, pulling us deeply into its imaginary realms. Four books (A Wizard of Earthsea, The Tombs of Atuan, The Farthest Shore, and Tehanu) tell the whole Earthsea cycle - a tale about a reckless, awkward boy named Sparrowhawk who becomes a wizard's apprentice after the wizard reveals Sparrowhawk's true name. The boy comes to realize that his fate may be far more important than he ever dreamed possible. Le Guin challenges her readers to think about the power of language, how in the act of naming the world around us we actually create that world. Teens, especially, will be inspired by the way Le Guin allows her characters to evolve and grow into their own powers.

Algebra - Wikipedia, Algebra - Wikipedia, the free encyclopedia, 'Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one of the main branches of pure mathematics.' back

Clifford algebra - Wikipedia, Clifford algebra - Wikipedia, the free encyclopedia, 'In mathematics, Clifford algebras are a type of associative algebra. As K-algebras, they generalize the real numbers, complex numbers, quaternions and several other hypercomplex number systems. The theory of Clifford algebras is intimately connected with the theory of quadratic forms and orthogonal transformations. Clifford algebras have important applications in a variety of fields including geometry, theoretical physics and digital image processing. They are named after the English geometer William Kingdon Clifford. back

Differential geometry - Wikipedia, Differential geometry - Wikipedia,the free encyclopedia, 'Differential geometry is a mathematical discipline that uses the techniques of differential calculus and integral calculus, as well as linear algebra and multilinear algebra, to study problems in geometry. The theory of plane and space curves and of surfaces in the three-dimensional Euclidean space formed the basis for development of differential geometry during the 18th century and the 19th century. Since the late 19th century, differential geometry has grown into a field concerned more generally with the geometric structures on differentiable manifolds.' back

Dirac equation - Wikipedia, Dirac equation - Wikipedia, the free encyclopedia, 'In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1⁄2 massive particles such as electrons and quarks, for which parity is a symmetry, and is consistent with both the principles of quantum mechanics and the theory of special relativity, and was the first theory to account fully for special relativity in the context of quantum mechanics. It accounted for the fine details of the hydrogen spectrum in a completely rigorous way.' back

It was first given by Bernard Bolzano in 1817. Augustin-Louis Cauchy never gave an (ε, δ) definition of limit in his Cours d'Analyse, but occasionally used ε, δ arguments in proofs. The definitive modern statement was ultimately provided by Karl Weierstrass.' back

Exterior algebra - Wikipedia, Exterior algebra - Wikipedia, the free encyclopedia, 'In mathematics, the exterior product or wedge product of vectors is an algebraic construction used in Euclidean geometry to study areas, volumes, and their higher-dimensional analogs. The exterior product of two vectors u and v, denoted by u ∧ v, is called a bivector and lives in a space called the exterior square, a geometrical vector space that differs from the original space of vectors. . . . The exterior algebra, or Grassmann algebra after Hermann Grassmann,[2] is the algebraic system whose product is the exterior product.' back

George Orwell, In Front of Your Nose, There is no use in multiplying examples. The point is that we are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield.' back

Heat death of the universe - Wikipedia, Heat death of the universe - Wikipedia, the free encyclopedia, 'The heat death is a possible final state of the universe, in which it has "run down" to a state of no thermodynamic free energy to sustain motion or life. In physical terms, it has reached maximum entropy. The hypothesis of a universal heat death stems from the 1850s ideas of William Thomson (Lord Kelvin) who extrapolated the theory of heat views of mechanical energy loss in nature, as embodied in the first two laws of thermodynamics, to universal operation' back

Matrix mechanics - Wikipedia, Matrix mechanics - Wikipedia, the free encyclopedia, 'Matrix mechanics is a formulation of quantum mechanics created by Werner Heisenberg, Max Born, and Pascual Jordan in 1925. Matrix mechanics was the first conceptually autonomous and logically consistent formulation of quantum mechanics. It extended the Bohr Model by describing how the quantum jumps occur. It did so by interpreting the physical properties of particles as matrices that evolve in time. It is equivalent to the Schrödinger wave formulation of quantum mechanics, and is the basis of Dirac's bra-ket notation for the wave function. back

Moyal bracket - Wikipedia, Moyal bracket - Wikipedia, the free encyclopedia, 'The Moyal bracket is a way of describing the commutator of observables in the phase space formulation of quantum mechanics when these observables are described as functions on phase space. It relies on schemes for identifying functions on phase space with quantum observables, the most famous of these schemes being Weyl quantization. It underlies Moyal’s dynamical equation, an equivalent formulation of Heisenberg’s quantum equation of motion, thereby providing the quantum generalization of Hamilton’s equations.' back

"That's not the way the world really works anymore," he continued. "We're an empire now, and when we act, we create our own reality. And while you're studying that reality—judiciously, as you will—we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors…and you, all of you, will be left to just study what we do.' back

Robert D. Klauber, Student Friendly Quantum Field Theory, 'There are two main branches to (ways to do) quantum field theory called • the canonical quantization approach, and • the path integral approach (also called the many paths or sum over histories approach). The first of these is considered by many, and certainly by me, as the easiest way to be introduced to the subject, since it treats particles as objects that one can visualize as evolving along a particular path in spacetime, much as we commonly think of them doing. The path integral approach, on the other hand, treats particles and fields as if they were simultaneously traveling all possible paths, a difficult concept with even more difficult mathematics behind it. This book is primarily devoted to the canonical quantization approach, though I have provided a simplified, brief introduction to the path integral approach in Chap. 18$near the end. Students wishing to make a career in field theory will eventually need to become well versed in both.' back

Variety (cybernetics) - Wikipedia, Variety (cybernetics) - Wikipedia, the free encyclopedia, 'The term Variety was introduced by W. Ross Ashby to denote the count of the total number of states of a system. The condition for dynamic stability under perturbation (or input) was described by his Law of Requisite Variety. Ashby says: Thus, if the order of occurrence is ignored, the set {c, b, c, a, c, c, a, b, c, b, b, a} which contains twelve elements, contains only three distinct elements- a, b, c. Such a set will be said to have a variety of three elements. He adds The observer and his powers of discrimination may have to be specified if the variety is to be well defined. Variety can be stated as an integer, as above, or as the logarithm to the base 2 of the number i.e. in bits.' back
