Seven years ago Northwestern University physicist Adilson E. Motter
conjectured that the expansion of the universe at the time of the big
bang was
highly chaotic. Now he and a colleague have proven it using rigorous
mathematical arguments.

How do gravity and drag affect a pitch? What's the best way
to make a curveball break? And what will break more: a beach ball or a
Wiffle
Ball? Through MIT's Science of Baseball Program, a group of local
middle school boys took to MIT's classrooms and fields this summer to
find the
answers to those questions.

The architect Mies van der Rohe is
famous for promoting the slogan “less is more.” But if Venkat
Chandrasekaran, a
graduate student in the Department of Electrical Engineering and
Computer
Science, had a slogan for his own work, it might be “more is less.”

An international team led by Univ. of Delaware researchers reports new findings about helium that may lead to more accurate standards for how temperature and pressure are measured. The scientists provide a new theoretical computation of the force acting between a pair of helium atoms, referred to as “pair potential,” that is more accurate than any published to date.

Two Univ. of Pennsylvania
mathematicians have found solutions to a 140-year-old, 7-dimensional
equation
that were not known to exist for more than a century despite its
widespread use
in modeling the behavior of gases.

In 2000, the Clay Mathematics Institute identified seven math problems worthy of a $1 million Millennium Prize. Grigory Perelman, a Russian recluse, is the only person to solve one: the Poincare conjecture, a geometry involving four dimensions. He will be offered the money, but he is unsure about accepting it.

In November 2007, surfer physicist Garrett Lisi published “An Exceptionally Simple Theory of Everything?” which proposed that the astoundingly complex and elegant E8 mathematical structure is the unifying “force” for everything. A rock-climbing mathematician, however, has recently used linear algebra and theorems to prove that Lisi’s theory does not hold water.

Univ. of Chicago scientists have successfully used geometrically patterned surfaces to influence the development of stem cells. The new approach is a departure from that of many stem-cell biologists, who focus instead on uncovering the role of proteins in controlling the fate of stem cells.

Calculations are fine, but seeing is believing. That's the thought behind a new paper by Rice Univ. students who decided to put to the test calculations made more than a century ago.
