Web kids.net.au Thesaurus Dictionary Kids Categories Encyclopedia ... Contents Encyclopedia - Mathematics Mathematics (often abbreviated to maths or, in American English math ) is commonly defined as the study of patterns of structure, change, and space. In the modern view, it is the investigation of axiomatically defined abstract structures using formal logic as the common framework, although some contest that this is necessary. The specific structures investigated often have their origin in the natural sciences , most commonly in physics , but mathematicians also define and investigate structures for reasons purely internal to mathematics, because the structures may provide, for instance, a unifying generalization for several subfields, or a helpful tool for common calculations. Finally, many mathematicians study the areas they do for purely aesthetic reasons, viewing mathematics as an art form rather than as a practical or applied science The word "mathematics" comes from the Greek máthema mathematikós ) means "fond of learning". Historically, the major disciplines within mathematics arose out of the need to do calculations in commerce, to measure land and to predict astronomical events. These three needs can be roughly related to the broad subdivision of mathematics into the study of structure, space and change.

Web kids.net.au Thesaurus Dictionary Kids Categories Encyclopedia ... Contents Encyclopedia - Theorem A theorem is a statement which can be proven true within some logical framework. Proving theorems is a central activity of mathematics . Note that 'theorem' is distinct from ' theory A theorem generally has a set-up - a number of conditions, which may be listed in the theorem or described beforehand. Then it has a conclusion - a mathematical statement which is true under the given set up. The proof, though necessary to the statement's classification as a theorem is not considered part of the theorem. In general mathematics a statement must be interesting or important in some way to be called a theorem. Less important statements are called: lemma : a statement that forms part of the proof of a larger theorem. Of course, the distinction between theorems and lemmas is rather arbitrary, since one mathematician's major result is another's minor claim. Gauss's Lemma[?] and Zorn's Lemma , for example, are interesting enough per se for some authors to stop at the nominal lemma without going on to use that result in any "major" theorem.

Ziegler Reviewed by Mary Shepherd In the preface of Proofs from THE BOOK , we read that "Paul Erdös often talked about The Book, in which God maintains the perfect proofs of mathematical theorems." As I read through the preface to this book, I began to ask some questions. What constitutes a "beautiful" proof? How about a "perfect" proof? Is there any such thing as a "perfect" proof? I don't know the answer to these questions. This book was inspired by Erdös and contains many of his suggestions. It was to appear in March, 1998 as a present to Erdös on his 85th birthday, but he died in the summer of 1997, so he is not listed as a co-author. Instead the book is dedicated to his memory. In the Number Theory section, the chapters are: (1) Six proofs of the infinity of primes, (2) Bertrand's postulate, (3) Binomial coefficients are (almost) never powers, (4) Representing numbers as sums of two squares, (5) Every finite division ring is a field, and (6) Some irrational numbers. I found most of these chapters to be somewhat difficult, requiring some background in algebra and analysis and even topology to be easily understandable. My favorite of these chapters was (4) because of the simplicity of statement of this theorem by Fermat, and the use of geometry to help visualize part of the solution. There was also a series of annoying but minor errors in chapter (6) in the reductions of the fractions on page 31.

The last book I chose to review, among the selection that the editor gave me, happened to also be on this wonderful topic; both times that was a surprise to me, and both times I did not complain. "Axiomatized arithmetic" is a pet passion. really wants to do is to take on the work of the likes of Cantor and Dedekind. And I don't blame her! From the back cover, which summarizes the book as well as anything I might say: "The content is of two types: ... material for a 'Transitions' course at the sophomore level: introductions to logic and set theory, discussions of proof writing and proof discovery, and introductions to the number systems... The second type of content is an introduction to the professional culture of mathematics. There are many things that mathematicians know but weren't exactly taught... the philosophy of mathematics, ethics in mathematical work, professional (including student) organizations, famous theorems, famous unsolved problems, famous mathematicians, discussions of the nature of mathematics research, and more."

In this session, you will look at a few proofs and several applications of one of the most famous theorems in mathematics: the Pythagorean theorem. Proof is an essential part of mathematics, and what separates it from other sciences. Mathematicians start from assumptions and definitions, then follow logical steps to draw conclusions. If the assumptions are correct and the steps are indeed logical, then the result can be trusted and used to prove further results. When a result has been proved, it becomes a theorem. For information on required and/or optional materials for this session, see Note 1 Part A: The Pythagorean Theorem Part B: Proving the Pythagorean Theorem Part C: Applications of the Pythagorean Theorem Homework In this session, you will learn how to do the following: Examine different formal proofs of the Pythagorean theorem Examine some applications of the Pythagorean theorem, such as finding missing lengths Learn how to derive and use the distance formula Throughout the session you will be prompted to view short video segments.

The Fermat's last theorem reference article from the English Wikipedia on 24-Jul-2004 (provided by Fixed Reference : snapshots of Wikipedia from wikipedia.org) Fermat's last theorem Fermat's last theorem (also called Fermat's great theorem ) is one of the most famous theorems in the history of mathematics . It states that: There are no positive natural numbers a b , and c such that in which n is a natural number greater than 2. The 17th-century mathematician Pierre de Fermat wrote about this in in his copy of Claude-Gaspar Bachet 's translation of the famous Arithmetica of Diophantus ': "I have discovered a truly remarkable proof but this margin is too small to contain it". This statement is significant because all the other theorems proposed by Fermat were settled, either by proofs he supplied, or by rigorous proofs found afterwards. Mathematicians were long baffled, for they were unable either to prove or to disprove it. The theorem was therefore not the last that Fermat conjectured, but the last to be proved . The theorem is generally thought to be the mathematical result that has provoked the largest number of incorrect proofs. For various special exponents n , the theorem had been proved over the years, but the general case remained elusive. In

New version of this book Next: Physics Up: Set theory Previous: Recursive functions Incompleteness theorem Recursive functions are good because we can, at least in theory, compute them for any parameter in a finite number of steps. As a practical matter being recursive may be less significant. It is easy to come up with algorithms that are computable only in a theoretical sense. The number of steps to compute them in practice makes such computations impossible. Just as recursive functions are good things decidable formal systems are good things. In such a system one can decide the truth value of any statement in a finite number of mechanical steps. Hilbert first proposed that a decidable system for all mathematics be developed. and that the system be proven to be consistent by what Hilbert described as `finitary' methods.[ ]. He went on to show that it is impossible for such systems to decide their own consistency unless they are inconsistent. Note an inconsistent system can decide every proposition because every statement and its negation is deducible. When I talk about a proposition being decidable I always mean decidable in a consistent system. S he is working with a statement that says ``I am unprovable in S''(128)[ ]. Of course if this statement is provable in

Dirac Notation: State Function: Each state function is denoted by a ket y Observable Quantites: If we denote an observable quantity by Q , we will denote the corresponding quantum mechanical operator by Q (i.e. the same symbol, but bold-faced). A quantum mechanical operator operates on kets and transforms them into other kets , as Q Q is defined if its effect on all allowable kets is known. In general, quantum mechanical operators need not commute ; i.e. Q Q Q Q The commutator of two operators (itself an operator) Q Q Q Q Q is a measure of whether or not two operators commute, and plays a very important role in quantum mechanics Eigenvalues and Eigenkets (Eigenvectors) If Q eigenket of the operator Q and a is called the associated eigenvalue A ket is often labelled by its eigenvalues, as Q > = a The completeness postulate y > may be expanded in terms of the eigenkets of Q , as y > = c > + c > + c where the c i y = c *c (with proper normalization) gives the probability that if a measurement of Q is made, the result will be a Dual (Bra) Space and Scalar Products To each ket there corresponds a dual or adjoint quantity called by Dirac a bra ; it is not a ket rather it exists in a totally different space.
