Der Freiburger Mathematiker Sebastian Goette hat eine Förderung der Simons Foundation eingeworben

Für seine Beteiligung am Projekt „Special Holonomy in Geometry, Analysis, and Physics” erhält der Freiburger Mathematiker Prof. Dr. Sebastian Goette insgesamt 650.000 US-Dollar für die kommenden vier Jahre. Geldgeber ist die Simons Foundation, eine Stiftung aus den USA, die mathematische und naturwissenschaftliche Grundlagenforschung fördert. Koordinator des Vorhabens ist der Mathematikprofessor Robert Bryant von der US-amerikanischen Duke University. Zudem sind Forscherinnen und Forscher der Stony Brook University und der University of California in den USA sowie des Imperial College London, des King’s College London, der University of Bath und der University of Oxford in England an der Kollaboration beteiligt.

In conversation with: Hee Oh, professor of mathematics

Hee Oh joined Yale’s math department this year from Brown. Here she talks about absolute abstraction, the joy of walking — and missing math during her years as a social activist.

You received your doctorate in mathematics from Yale in 1997, then served on the faculties of Princeton, Cal Tech, and Brown, among others. What drew you back to Yale?

The math department at Yale has been well known for its strength in Lie groups, geometry, and dynamics for a long time. It was an honor and in itself a big draw for me to be asked to participate in continuing this tradition. In the end, however, I felt in my Christian faith that God was leading me this way, and I made the final decision accordingly. (more…)

Cassini Spies Bright Venus from Saturn Orbit

PASADENA, Calif. – A distant world gleaming in sunlight, Earth’s twin planet, Venus, shines like a bright beacon in images taken by NASA’s Cassini spacecraft in orbit around Saturn.

One special image of Venus and Saturn was taken last November when Cassini was placed in the shadow of Saturn. This allowed Cassini to look in the direction of the sun and Venus, and take a backlit image of Saturn and its rings in a particular viewing geometry called “high solar phase.” This observing position reveals details about the rings and Saturn’s atmosphere that cannot be seen in lower solar phase.

Electrically Spun Fabric Offers Dual Defense Against Pregnancy, HIV

The only way to protect against HIV and unintended pregnancy today is the condom. It’s an effective technology, but not appropriate or popular in all situations.

A University of Washington team has developed a versatile platform to simultaneously offer contraception and prevent HIV. Electrically spun cloth with nanometer-sized fibers can dissolve to release drugs, providing a platform for cheap, discrete and reversible protection. (more…)

Learning About Spatial Relationships Boosts Understanding of Numbers

Children who are skilled in understanding how shapes fit together to make recognizable objects also have an advantage when it comes to learning the number line and solving math problems, research at the University of Chicago shows.

The work is further evidence of the value of providing young children with early opportunities in spatial learning, which contributes to their ability to mentally manipulate objects and understand spatial relationships, which are important in a wide range of tasks, including reading maps and graphs and understanding diagrams showing how to put things together. Those skills also have been shown to be important in the Science, Technology, Engineering and Mathematics (STEM) fields. (more…)

Exploring the Ocean in Our Brains with Jaron Lanier

*Jaron Lanier has spent decades thinking about technology and the ways we use – and misuse – it. He also has been thinking long and hard about using avatars to access the untapped potential of our brains.*

REDMOND, Wash. – Nov. 9, 2011 – One evening last November, Jaron Lanier queued up outside a video game store in California and counted down the minutes until he could buy Kinect for Xbox 360. Lanier – a technologist, computer scientist, composer, and one of Time magazine’s “100 Most Influential People of 2010 – was just as excited to get his hands on Microsoft’s motion-sensing camera as the other gamers in line, most of whom he quickly realized were half his age. He was only slightly embarrassed by the observation.

“As a grownup and as a father I can’t believe I did that,” said Lanier, a partner architect for Microsoft Research. “But I was just so amazed it was really happening.” (more…)
