What is Scientific Literacy Anyway?
Scientific literacy means that a person can ask, find, or determine answers to questions derived from curiosity about everyday experiences.
It means that a person has the ability to describe, explain, and predict natural phenomena. Scientific literacy entails being able to read with understanding articles about science in the popular press and to engage in social conversation about the validity of the conclusions. Scientific literacy implies that a person can identify scientific issues underlying national and local decisions and express positions that are scientifically and technologically informed. A literate citizen should be able to evaluate the quality of scientific information on the basis of its source and the methods used to generate it. Scientific literacy also implies the capacity to pose and evaluate arguments based on evidence and to apply conclusions from such arguments appropriately.

TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages.
Dance Your Ph.D
The top prize for the 2013 “Dance Your Ph.D.” contest goes to … Cedric Tan, a biologist at the University of Oxford in the United Kingdom, who finished his Ph.D. there last year with a thesis titled “Sperm competition between brothers and female choice.” His dance interpretation of that research illustrates the chicken mating process using a range of styles, from swing and water ballet—yes, in actual water—to modern jazz and what can only be described as cockfighting.
The contest, now in its 6th year, is sponsored by Science magazine and AAAS (publisher of ScienceNOW). Based on votes from previous winners and an independent panel of artists and scientists, Tan won both the Biology category and the overall prize: $1000 and a trip—sponsored by HighWire Press—to screen his video at Stanford University in Palo Alto, California.

How Many Dimensions Does the Universe Really Have?
By Paul Halpern on Thu, 03 Apr 2014
Paul Halpern is Professor of Physics at the University of the Sciences in Philadelphia. A prolific author, he has written thirteen science books and dozens of articles. His interests range from space, time and higher dimensions to cultural aspects of science.
An engineer, a mathematician and a physicist walk into a universe. How many dimensions do they find?
The engineer whips out a protractor and straightedge. That’s easy, she says. With her instruments she demonstrates the trio of directions at right angles to each other: length, width and height. “Three,” she reports.
The mathematician gets out his notepad and creates a list of regular, symmetric geometric shapes with perpendicular sides. Squares have four linear edges, he notes. Cubes have six square sides. By extrapolation, hypercubes have eight cubic sides. Continuing the pattern, he realizes that he could keep going forever. “Infinity,” he says.
Finally it is the physicist’s turn. She gazes at the stars and carefully records their behavior. She determines that they attract each other through gravity, which drops off as the square of their mutual distances—an indication, she thinks, of three dimensions. However, once she derives the equation for how their light moves through space, she finds that it is best expressed in four dimensions. Then, after much thought, she tries to think of ways to describe gravity and light in a common theory, which seems to require at least ten dimensions. “Three, four, or maybe even more,” she chimes in.
Let’s see how she reached her conclusions.
In 1917, Austrian physicist Paul Ehrenfest wrote a thought-provoking piece, “In what way does it become manifest in the fundamental laws of physics that space has three dimensions?” (pdf). In the article he enumerated evidence that three dimensions are perfect for describing our world.
He noted, for example, that the stable orbits of planets in the solar system and the stationary states of electrons in atoms require inverse-squared force laws. If gravity, for instance, dropped off with the cube instead of the square of distance from the Sun, the planets would not follow steady, elliptical paths.
Let’s think of what an inverse-squared law means. Imagine a bubble that roughly encompasses a planet’s orbit. The strength of the Sun’s gravitational field at that distance is diluted over the bubble’s surface area. Surface area is proportional to radial distance squared, explaining why gravity drops off by that factor. Because a bubble, including its interior, is three-dimensional, space itself must be as well. In short, the fact that gravity tapers off with distance squared—the amount of a bubble’s surface area—implies three-dimensionality.
The universe is not just space, though. As Russian-German mathematician Hermann Minkowski demonstrated, Einstein’s special theory of relativity, postulated to explain how light moves at a constant speed relative to all observers, can best be expressed in four dimensions. Instead of considering space and time independently, he proposed a unified vision of spacetime. In his general theory of relativity, Einstein made use of the concept and described gravity using a dynamic four-dimensional model.
