Created by Tormod Guldvog Last updated September 14 2001 Viewed 4895 times. Kepler's Conjecture is all about packing spheres into a box. Do you think it is a worthy topic for scientific study? Yes No results Most of us have heard about these theories, or at least some of them. But although they may be famous, they are not necessarily easy to understand. Take Kepler's Conjecture, for example. It simply states that there is an ultimate way to pack spheres into a box. It has taken centuries of experiments and calculations to show that there are in fact an endless number of ways to do it - and scientists have yet to prove that there is one way which is better than the others. Another great idea is Drake's Equation, which is meant to show that there is a good possibility that there are aliens out there. It is perhaps the least scientific of all the ideas we feature below, but it is also much easier to understand than the rest. Not to mention Fermat's Last Theorem, of course, which haunted mathematicians for ages until it was finally proven in the 1990s.

Gödel's Theorems and Truth Author: Dan Graves Subject: Date: Essays by Author Essays by Subject Essays by Date Summary Famed mathematician Kurt Gödel proved two extraordinary theorems. Accepted by all mathematicians, they have revolutionized mathematics, showing that mathematical truth is more than logic and computation. Does Gödel's work imply that someone or something transcends the universe? Truth and Provability Kurt Gödel has been called the most important logician since Aristotle.(1) Such praise is evidence of how seriously Gödel's ideas are taken by mathematicians. His two famous theorems changed mathematics, logic, and even the way we look at our universe. This article explains what Gödel proved and why it matters to Christians. But first we must set the stage. A very simple formal system cannot support number theory but such a system is easily proven to be self-consistent. All we have to do is to show that it can't make a silly proof such as A=Non-A, which would be like saying 2=17. To handle number theory a complex formal system is needed. But as systems get more complex, they are harder to prove consistent. One result is that we don't know if our number theories are sound or if there are contradictions hidden in them. Gödel worked with such problems. He especially studied undecidable statements. An undecidable statement is one which can neither be proven true nor false in a formal system. Gödel proved that any formal system deep enough to support number theory has at least one undecidable statement.(2) Even if we know that the statement is true, the system cannot prove it. This means the system is incomplete. For this reason, Gödel's first proof is called "the incompleteness theorem".

A Math Forum Project Introduction Mathematics has been vital to the development of civilization; from ancient to modern times it has been fundamental to advances in science, engineering, and philosophy. As a result, the history of mathematics has become an important study; hundreds of books, papers, and web pages have addressed the subject in a variety of different ways. The purpose of this site is to present a small portion of the history of mathematics through an investigation of some of the great problems that have inspired mathematicians throughout the ages. Included are problems that are suitable for middle school and high school math students, with links to solutions, as well as links to mathematicians' biographies and other math history sites. WARNING: Some of the links on the page in this site lead to other math history sites. In particular, whenever a mathematician's name is highlighted, you can follow it to link to his biography in the MacTutor archives. Table of Contents The Bridges of Konigsberg - This problem inspired the great Swiss mathematician Leonard Euler to create graph theory, which led to the development of topology. The Value of Pi - Throughout the history of civilization various mathematicians have been concerned with discovering the value of and different expressions for the ratio of the circumference of a circle to its diameter.

www.mathematik.tu-darmstadt.de/~kgb/prosem.html Proseminar II - Analysis and Geometry SS 03, in English, Mondays, 11:40-13:20, S1 03/12 The book The Proseminar is based on an attractive book: Proofs from THE BOOK by M. Aigner and G. Ziegler; make sure you get the second edition (Springer 2001). In the preface, the authors explain what made them to collect the material for the 32 self-contained chapters, and they explain the title: Paul Erdos liked to talk about The Book , in which God maintains the perfect proofs for mathematical theorems. [...] We have no ... characterization of what constitutes a proof from The Book ; all we offer here is examples ..., hoping that our readers will share our enthusiasm about brilliant ideas, clever insights, and wonderful observations. [...] A limiting factor for our selection of topics was that everything in this book is supposed to be accessible to readers whose backgrounds include only a modest amount of technique... A little linear algebra, some basic analysis [...] should be sufficient to understand and enjoy everything in this book. Presentations The main goal is a good presentation. The chapters leave room for a choice of material to present: You can select from alternative proofs, skip or add material, present the problem by experiment or with additional examples, build a model to illustrate, etc.

Read This! The MAA Online book review column Proofs from THE BOOK by Martin Aigner and Günter M. 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.

1. INTRODUCTION. COGNITIVE VISUALIZATION OF NUMBER-THEORETICAL ABSTRACTIONS ]: "... Continuum Hypothesis is a rather dramatic example of what can be called (from our today's point of view) an absolutely undecidable assertion, ..." (p.13). The complete absence of any progress in the Continuum Hypothesis proof (or dispoof) on the way of modern meta-mathematics during last decades confirms the validity of Cohen's pessimism. So, it is obviously that new ways are necessary here. One of such new ways - a NON-meta-mathematical and NON-mathematical-logic way based on a so-called scientific cognitive computer visualization technique - to a new comprehension of the Continuum Problem itself is offered below. ]. For example, in classical Number Theory (NT) such the main feature giving rise to many famous NT-problems (such as Fermat's, Goldbach's, Waring's problems) is, by B.N.Delone and A.Ya.Hintchin, a hard comprehended connection between two main properties of natural numbers - their additivity and multiplicativity. Nevertheless, by means of CV-approach, we visualized this twice abstract connection in the form of color-musical 2D-images (so-called pythograms) of abstract NT-objects, and obtained really a lot of new NT-results. In particularly, we generalized well-known Classical Waring's Problem, generalized and proved the famous theorems of Hilbert, Lagrange, Wieferich, Balasubramanian, Desouillers, and Dress, discovered a new type of NT-objects, a new universal additive property of the natural numbers and a new method, - the so-called Super-Induction method, - for the rigorous proving of general mathematical statements of the form

Dunham Course Objectives This is a capstone course for mathematics majors. Its purpose is to let you think about and reflect on what mathematics is and to tie together your years of studying mathematics. Dunham's book, Journey Through Genius , covers the story of mathematics from the 5th century B.C.E. up to the 20th Century C.E. by looking at some famous problems and theorems, and the mathematicians who worked on them. The book is many things. It's a selective history of mathematics, it's a look at some of the famous and colorful "characters" who were mathematicians but most of all it's a well-written presentation of twelve interesting and famous theorems in mathematics. Through the twelve theorems, Dunham presents his idea of what makes a theorem great! . The book is well written, fun to read and it will give you a deeper appreciation of the unique endeavor we call mathematics . Enjoy!

An Infinity Of Primes Mersenne Numbers Largest Prime Numbers Famous Theorems Diophantine Equations Solving Diophantine Equations Fermat's Last Theorem History of the Theorem Proof Of The Theorem Number Theory Number theory is the branch of mathematics concerned with studying the properties and relations of integers. Many of these problems are concerned with the properties of prime numbers. Number theory also includes the study of irrational numbers, transcendental numbers, Diophantine equations, and continued fractions. There are a number of branches of number theory, including algebraic number theory, analytic number theory, geometric number theory, and probabilistic number theory. Algebraic number theory is the study of numbers that are the roots of polynomial equations with integer coefficients, and includes the study of Gaussian integers. Goldbach's Conjecture One of the most famous problems in number theory is Goldbach's conjecture, proposed in 1742 by Christian Goldbach (1690-1764), the Prussian-born number theorist and analyst, in a letter to Leonhard Euler. Goldbach's conjecture states that any even number greater than or equal to 6 can be expressed as the sum of two odd prime numbers (for example, 6 = 3 + 3, 8 = 5 + 3, 48 = 29 + 19). Although there is every reason to believe that this conjecture is true, and computers have been used to verify it for some very large numbers, it has never been proved. Goldbach's conjecture is a good example of the way in which a problem in number theory can be stated very simply yet be very difficult to solve.

The World of Numbers This page, like the companion Science page , contains items and links that appeal to me for one reason or another. Here you will find various topics related to mathematics and statistics , including links to reference material, tutorials, Macintosh freeware, and miscellaneous tidbits as well as to other sites like this one. The list is not meant to be comprehensive and the selection is based, as always, on my personal perspective . Thus, this page will always be under construction! Mathematics It would be difficult to find any other subject, of comparable relevance and importance, about which so many are so proud of their ignorance. Even the most fastidious individuals, who would never tolerate the unforgivable solecism of a split infinitive, will not hesitate to proclaim, to one and all, their utter inadequacy when it comes to anything pertaining to numbers. This includes activities even as mundane as rescaling a recipe, reading a weather map, or computing the total cost of a mortgage. Tell people that the Sun is far away and they will nod their head and try to look intelligent. Say that it is 93,000,000 miles away and their eyes will start to glaze over as they search for some means of escape. If you are reading this page, then you are likely in that happy minority who know better. Therefore, you might find things here that you will appreciate.

19. Disproving Statements There are many famous conjectures and famous theorems that were conjectures formany years (The 4 color theorem and Fermat's Last Theorem, for example). http://www.math.csusb.edu/notes/proofs/pfnot/node3.html

Next: Types of Proof Up: NOTES ON METHODS OF Previous: Definitions and Theorems Disproving Statements Some conjectures are false. Verifying that a conjecture is false is often easier than proving a conjecture is true. Despite that, showing a conjecture is false may have its own challenges and usually requires a deep knowledge of the subject. Some statements are often shown to be false by a counter examples . Such statements have the form ``For all x in X conclusion ''. This is shown to be false by finding one element of X which does not satisfy the conclusion. As an example, consider the statement ``For all prime numbers p p +1 is prime''. This statement is true for the primes 2, 3 and 5. It is also true for the primes 11 and 23. However, the statement is an assertion for all primes. Clearly the statement is not true for the prime 7 (since 15 = 3 5) and we have obtained a counter example to the statement. For finite sets, statements of the form such as ``There exists an x such that conclusion '' can be refuted by example. By testing each element of the set and showing no element satisfies the conclusion we have shown the statement is false through an
