BUFFALO, N.Y. -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that the early universe -- which exploded from a single point and was very, very small at first -- was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today).

Photography as both a profession and a hobby is an incredibly expansive topic that covers a remarkably vast range of subjects from science and art. No matter where you lie on the professional spectrum, there is simply always more to learn.
SExpand Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here.

Curve S is n2, so the product curves on the right side of the spiral are n2 – 1, n2 – 4, n2 – 9, etc. Curve P is n2 + n so the curves on the left side are n2 + n – 2, n2 + n – 6, n2 + n – 12, etc. These curves have many interesting properties.. I'll point out just a few. Product curves
Imagine a circle that contains all of human knowledge: By the time you finish elementary school, you know a little: By the time you finish high school, you know a bit more:
Layout can both be one of the easiest and one of the trickiest facets of web design. Sometimes a designer can bust out an amazing layout in minutes and sometimes that same designer can struggle for the better part of day with the same task. Each project is unique and calls for a unique solution, but I’ve found it helpful to keep a few rock solid and incredibly versatile alignments in mind that I can bust out when I get stuck. The ten layouts below should be enough to get you through even the worst cases of designer’s block when you can’t figure out the best way to arrange the content on your page. Keeping It Simple
IP over Avian Carriers A homing pigeon can carry Internet Protocol traffic. In computer networking, IP over Avian Carriers (IPoAC) is a humorously-intended proposal to carry Internet Protocol (IP) traffic by birds such as homing pigeons. IP over Avian Carriers was initially described in RFC 1149, a Request for Comments (RFC) issued by the Internet Engineering Task Force (IETF) written by D. Waitzman and released on April 1, 1990. It is one of several April Fools' Day RFCs. Waitzman described an improvement of his protocol in RFC 2549, IP over Avian Carriers with Quality of Service (1 April 1999).

First published Wed Oct 10, 2012 Existence raises deep and important problems in metaphysics, philosophy of language, and philosophical logic. Many of the issues can be organized around the following two questions: Is existence a property of individuals? and Assuming that existence is a property of individuals, are there individuals that lack it?

These pages introduce some fundamentals of genetic algorithms. Pages are intended to be used for learning about genetic algorithms without any previous knowledge from this area. Only some knowledge of computer programming is assumed. You can find here several interactive Java applets demonstrating work of genetic algorithms.
Psychological ("personality") Types According to Jung's theory of Psychological Types we are all different in fundamental ways. One's ability to process different information is limited by their particular type. These types are sixteen. People can be either Extroverts or Introverts, depending on the direction of their activity ; Thinking, Feeling, Sensing, Intuitive, according to their own information pathways; Judging or Perceiving, depending on the method in which they process received information.
