ESSAY The Special Theory of Relativity
by J. L. Safko
A. Principle of Relativity
Newton's theory of gravity, first studied in Unit 3, is intimately related to his concept of space and time. He considered space and time to be absolute concepts which existed independently of the material universe. Space was a stage in which the planets and stars existed. As time passed, the objects in the material universe evolved against the fixed background of space. Newton also formalized the concept of the inertial frame (or inertial coordinate system). A coordinate system (or coordinate frame) is a grid of rods and clocks at rest with respect to each other that spans a region of space. A simplified drawing of a coordinate system is shown in Fig. 56-1. Using this coordinate system we can describe events. Events are things that can be located at a particular place in space and that occur at a given time. The flashbulb firing on your camera would be an example of an event. The measurement of an event is determining the position and time of an event. We also term this measuring the coordinates of an event. An inertial frame (or an inertial coordinate frame) is a coordinate system in which Newton's first law holds. Newton's first law, as given in Unit 3, is that in the absence of outside forces any body moves with constant velocity. Any coordinate system moving with constant velocity with respect to an inertial system is also an inertial system. These inertial frames were assumed by Newton to be of infinite extent. They covered the entire universe. According to Newton, once you know any inertial frame, you know them all, since each differs from another by a constant velocity.

102. Introduction To The Theory Of Enformed Systems
A universal conserved organizing principle called enformy is the basis for holistic science which explains life, consciousness and psi phenomena.
Introduction to the Theory of Enformed Systems A Tutorial on Reductionism vs. Holism We introduce the Theory of Enformed Systems (TES) with three statements that relate it to the paradigms of what Thomas Kuhn termed "normal science." 1. TES is radically related to the prevailing scientific worldviews because it's a theory of organization per se the root of all organized systems. 2. TES can't be understood in terms of other paradigms because it's not derived from them. 3. TES is not only deep, it is broad. It's a transdisciplinary conceptual model that explains the basic behaviors and properties of all of the systems studied in physics, chemistry, biology, psychology, parapsychology, sociology, and their subdisciplines. If you doubt the validity of this extraordinary claim, please read on to see our reasons for making it. We note first that science is a human endeavora human invention that's operated by humans within human social institutions. This is so obvious, it goes without saying. And here we encounter a serious problem in normal sciencenot saying it. If we don't address the humanness of science, we can't recognize the emotional and cognitive processes that resist scientific revolutions. Nor can we appreciate how our motives, impeded by our limitations, foster our clinging to misleading mythologies. For instance, our motive to understand the natural world exposes our limitations in comprehending the whole of Nature. Our realizing these limits, in turn, induces us to create myths that help us believe we can transcend our limitations. Relying on these myths, we believe we can capture and understand Nature.

Groups, in general
3.1.3. Definition. A group (G, ) is a nonempty set G together with a binary operation on G such that the following conditions hold:
(i) Closure: For all a,b G the element a b is a uniquely defined element of G.
(ii) Associativity: For all a,b,c G, we have a (b c) = (a b) c.
(iii) Identity: There exists an identity element e G such that e a = a and a e = a for all a G.
(iv) Inverses: For each a G there exists an inverse element a G such that a a = e and a a = e.
We will usually simply write ab for the product a b. 3.1.6. Proposition. (Cancellation Property for Groups) Let G be a group, and let a,b,c G.
(a) If ab=ac, then b=c.
(b) If ac=bc, then a=b.
3.1.8. Definition. A group G is said to be abelian if ab=ba for all a,b G. 3.1.9. Definition. A group G is said to be a finite group if the set G has a finite number of elements. In this case, the number of elements is called the order 3.2.7. Definition.

    Category Theory
    1. General Definitions, Examples and Applications
    defined as sets, category theory cannot provide a philosophically enlightening foundation for mathematics. In terms of collections, a category C can be described as a collection Ob , the objects of C , which satisfy the following conditions: For every pair a b of objects, there is a collection Mor a b ), namely, the morphisms from a to b in C (when f is a morphism from a to b , we write f a b For every triple a b and c of objects, there is a partial operation from pairs of morphisms in Mor a b ) X Mor b c ) to morphisms in Mor a c ), called the composition of morphisms in C
    (when f a b and g b c g o f a c is their composition);

    A Mathematical Theory of Communication by Claude E. Shannon
    A Note on the Edition Claude Shannon's ``A mathematical theory of communication'' was first published in two parts in the July and October 1948 editions of the Bell System Technical Journal [1]. The paper has appeared in a number of republications since:
    • The original 1948 version was reproduced in the collection Key Papers in the Development of Information Theory [2]. The paper also appears in Claude Elwood Shannon: Collected Papers [3]. The text of the latter is a reproduction from the Bell Telephone System Technical Publications , a series of monographs by engineers and scientists of the Bell System published in the BSTJ and elsewhere. This version has correct section numbering (the BSTJ version has two sections numbered 21), and as far as we can tell, this is the only difference from the BSTJ version.
    • Prefaced by Warren Weaver's introduction, ``Recent contributions to the mathematical theory of communication,'' the paper was included in The Mathematical Theory of Communication

    Fundamentals of Model Theory
    William Weiss and Cherie D'Mello
    Department of Mathematics
    University of Toronto The textbook is available in several formats.
    Model Theory is the part of mathematics which shows how to apply logic to the study of structures in pure mathematics. On the one hand it is the ultimate abstraction; on the other, it has immediate applications to every-day mathematics. The fundamental tenet of Model Theory is that mathematical truth, like all truth, is relative. A statement may be true or false, depending on how and where it is interpreted. This isn't necessarily due to mathematics itself, but is a consequence of the language that we use to express mathematical ideas. What at first seems like a deficiency in our language, can actually be shaped into a powerful tool for understanding mathematics. This book provides an introduction to Model Theory which can be used as a text for a reading course or a summer project at the senior undergraduate or graduate level. It is also a primer which will give someone a self contained overview of the subject, before diving into one of the more encyclopedic standard graduate texts. Any reader who is familiar with the cardinality of a set and the algebraic closure of a field can proceed without worry. Many readers will have some acquaintance with elementary logic, but this is not absolutely required, since all necessary concepts from logic are reviewed in Chapter 0. Chapter 1 gives the motivating examples and we recommend that you read it first, before diving into the more technical aspects of Chapter 0. Chapters 2 and 3 are selections of some of the most important techniques in Model Theory. The remaining chapters investigate the relationship between Model Theory and the algebra of the real and complex numbers. Thirty exercises develop familiarity with the definitions and consolidate understanding of the main proof techniques.

    Magnetic Reconnection Theory
    2 Aug - 27 Aug 2004 Organisers Professor J Birn ( Los Alamos ), Professor T Forbes ( Durham ), Professor ER Priest ( St Andrews
    Programme theme
    Magnetic reconnection is a fundamental process in a magnetized plasma or fluid at high magnetic Reynolds number, whereby magnetic field lines are broken and reconnected in an electric current singularity that is resolved by magnetic diffusion. It has the effect of converting inflowing magnetic energy into bulk kinetic energy, heat and fast particle energy. Reconnection is responsible for many dynamic processes in the Sun, the Magnetosphere, the laboratory and many astrophysical bodies, but in this Programme we shall be focusing on the fundamentals of the process and on the first two fields. In the Sun, solar flares represent an explosive conversion of stored magnetic energy by reconnection into other forms. In addition, reconnection is likely to be heating the solar corona in many small current sheets to several million degrees by comparison with the solar surface temperature of only 6000 degrees. In the Magnetosphere, the solar wind sweeps back the Earth's magnetic field to form a tail. Occasionally, the field in the tail can reconnect in an explosive manner, producing a geomagnetic substorm. Reconnection can also occur sporadically over the front face of the magnetopause bounding the geomagnetic and interplanetary magnetic field to produce so-called 'flux-transfer events'.

    This essay is a must-read for anyone who wants to participate in It lays out the land for evolutionists and creationists alike, presenting the ideas behind and the evidence for biological evolution.
    What is Evolution?
    All too often creationists spend their time arguing with a straw-man caricature of evolution. This brief essay presents a definition of evolution that is acceptable to evolutionists.
    Evolution is a Fact and a Theory
    Biologists consider evolution to be a fact in much the same way that physicists do so for gravity. However, the mechanisms of evolution are less well understood, and it is these mechanisms that are described by several theories of evolution.
    The Modern Synthesis of Genetics and Evolution
    Darwin developed his theory of natural selection without any knowledge of genetics. Since Darwin, genetics and evolution have been synthesized, and natural selection is no longer considered to be the only evolutionary mechanism.
