What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem. Shu, an associate professor at National Tsing Hua University in Taiwan, explains in a study posted at arXiv.org that the new models emerge from a new perspective of some of the most basic entities: time, space, mass, and length. “We view the speed of light as simply a conversion factor between time and space in spacetime,” Shu writes. As Shu writes in his paper, the newly proposed models have four distinguishing features:

BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. BRIAN GREENE: We really may live in a universe with more dimensions than meet the eye. AMANDA PEET (University of Toronto): People who have said that there were extra dimensions of space have been labeled crackpots, or people who are bananas. NARRATOR: A mirage of science and mathematics or the ultimate theory of everything? S. We see 400 employees in three years.

Help Exchange: free volunteer work exchange abroad Australia New Zealand Canada Europe Physics Flash Animations - StumbleUpon We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from In addition, I have prepared a small tutorial in using Flash to do Physics animations.

DAD: Yes, I was in the shower. SARAH: Why? DAD: I was dirty. The shower gets me clean. DAD: Why does the shower get me clean? SARAH: Yes. DAD: Because the water washes the dirt away when I use soap.

DAD: That is an EXCELLENT question. DAD: Why does soap form micelles? DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. SARAH: Aidrofawwic DAD: And can you say ‘hydrophobic’? DAD: Excellent! DAD: Why does it mean that? DAD: It’s Greek! SARAH: Like a monster? DAD: You mean, like being afraid of a monster?
