Extractions: This page will build a list of open research questions at the so-called bleeding edge of science. This page makes no attempt to be complete, or even up-to-date. I will attempt to address each science wherever I can dig up the most important problems. How, and when, did agriculture develop? How can modern analytical techniques be used to gather information about artifacts? How did the first nations come into being? How do aboriginal cultures approach astronomy? How do complex societies come to be? How do human beings adapt? How do we accurately date artifacts? How do we reconstruction prehistoric and ancient life. In what ways did ancient peoples use plants? What were the environments of prehistoric and ancient humans like?. Are there active galactic nuclei? Are there black holes? Are there dwarf galaxies? Can we use cosmic rays for imaging? How are elements created in a star? How are large-scale cosmic structures formed? How are black holes formed? How are neutron stars formed? How can we detect Doppler shifts of spectral lines in the X-ray spectra of clusters?

Unsolved Problems
Including the list of 50 problems of Bondy and Murty with current status. Compiled by Stephen C. Locke.
http://www.math.fau.edu/locke/unsolved.htm

Extractions: Some of these problems have been solved (and thus the title is slightly incorrect) and I won't claim to be familiar with all current results. If you find that one of them has been solved (or even that some reasonable progress has been made), please e-mail me. ( How to contact me .) If I receive comments on these new problems, I will of course post those that seem suitable (and, at that point, I would presumably post the problem to which the comment refers). Note, however, the publisher does have a site for the text, http://blogs.springer.com/bondyandmurty/ , and it would seem reasonable that one should post comments there. Also, I'm not giving you all of the references in

Games On Graphs
Students can understand and work on an unsolved problem in mathematics.
http://www.c3.lanl.gov/mega-math/workbk/graph/grthree.html

Extractions: Students can understand and work on an unsolved problem in mathematics. There is a good chance that this problem can be solved by someone who spends enough time experimenting with it. The only skills required to work on it are the ability to draw dots and connect them with lines, and the understanding of four ideas related to graphs: degree diameter planarity , and size . (These concepts can be explored in the story Superperson Saves the Monster Materials Instructions Ideas for discussion Explain to students that you are going to tell them about a problem in mathematics that is easy to understand that no one has solved yet. There is no reason why one of them could not be the person to solve it. A famous mathematician, Paul Erdos, has offered a large cash prize for the person who succeeds in drawing the graph that solves this problem. They could win it.
Open Problems In Continuum Theory
Apr 3, 2010 Open problems in topology, Edited by Jan van Mill and George M. Reed, North Holland Publishing Co., Amsterdam, 1990 (H. Cook, W. T. Ingram
http://web.mst.edu/~continua/

Extractions: Last Modified Saturday, 03-Apr-2010 14:05:33 CDT In the first half of the twentieth century, when foundations of general topology had been established, many famous topologists were particularly interested in the properties of compact connected metric spaces called continua . It seems that studying continua was for them a major source of new ideas. These new ideas were later generalized and formed into developed topological theories. What emerged as continuum theory is a continuation of this early study of continua. Continuum theory is not exactly a "theory" separated from other areas of topology and mathematics by a fixed set of axioms or specific methods. Its identity is rather defined by special type of questions asked in this area. Now, when basic general topology is already established, many deep but naturally and simply formulated problems in continuum theory still remain open. Due to these problems, continuum theory remains a remarkably fresh area in topology. We consider these problems interesting and important. We think that it would be useful to find a place where they could be continuously exposed and updated. Therefore, we have decided to present this web site so that everyone interested, especially beginners, can find them together with some basic information necessary to start working on these problems. This is the second edition of our list. The last version of the previous edition can be found
Problems In Topological Graph Theory
Web text by Dan Archdeacon with a list of open questions in topological graph theory.
http://www.emba.uvm.edu/~archdeac/newlist/problems.html

Extractions: Burlington VT 05401-1455 USA Do you think you've got problems? I know I do. This paper contains an ongoing list of open questions in topological graph theory. If you are interested in adding a problem to this list please contact me at the addresses above. The spirit is inclusive-don't submit a problem you're saving for your graduate student. If it appears here, it's fair game. If you solve one of the problems, know some additional history, or recognize it as misphrased or just a stupid question, please let me know so that I can keep the list up-to-date. I've taken quite a bit of liberty editing the submissions. I apologize for any errors introduced. Enjoy my problems-I do!

It contains links to numerous other sites with material of interest for graph coloring. For general information related to combinatorial mathematics, consult the World Combinatorics Exchange Introduction to Graph Theory by Douglas West (Prentice Hall 1996 and 2001) is a standard textbook, used in many places, with a well written chapter on graph coloring, but colorings appear also in several other places in the book. It has a final chapter with more advanced material. Douglas west also maintains a webpage with open problems.

Extractions: Catalan's Conjecture and ) are the only consecutive powers (excluding and 1). In other words, is the only nontrivial solution to Catalan's Diophantine problem The special case and is the case of a Mordell curve Interestingly, more than 500 years before Catalan formulated his conjecture, Levi ben Gerson (1288-1344) had already noted that the only powers of 2 and 3 that apparently differed by 1 were and (Peterson 2000). three consecutive powers exist (Ribenboim 1996), and it was also known that 8 and 9 are the only consecutive cubic and square numbers Tijdeman (1976) showed that there can be only a finite number of exceptions should the conjecture not hold. More recent progress showed the problem to be decidable in a finite (but more than astronomical) number of steps and that, in particular, if and are powers , then (Guy 1994, p. 155). In 1999, M. Mignotte showed that if a nontrivial solution exists, then (Peterson 2000). It had also been known that if additional solutions to the equation exist
