UTRECHT, The Netherlands, June 15 /PRNewswire/ -- The largest global study on connection, performed in 14 countries among 10,000 respondents, shows that strongly connected people have more enjoyment in their lives and in their work. They are not only happier, but more successful. Strongly connected people have a better idea of what they want in life and how they can achieve it. The study, carried out by &intoconnection, proves that connection has a tremendous positive influence on...

A problem at the interface of two mathematical areas, topology and algebraic geometry, that was formulated by Friedrich Hirzebruch, had resisted all attempts at a solution for more than 50 years. The problem concerns the relationship between different mathematical structures. Professor Dieter Kotschick, a mathematician at the Ludwig-Maximilians-Universität (LMU) in Munich, has now achieved a breakthrough. As reported in the online edition of the journal Proceedings of the National...

A Southern California calculus teacher says he's selling ad space on his test papers to make up for a cut in his supply budget. Tom Farber, a teacher at a Rancho Bernardo high school, said the district cut his annual copying budget to $316 when he needs more than $500 to print enough tests to ensure students receive adequate practice for tough tests they'll take in the future, such as the Advanced Placement Exam, USA Today reported Tuesday. Farber, 47, said tough times call for tough actions...

Directing a driver's gaze results in smoother steering - Study may inform the next generation of in-car driving assistance systems Typically, drivers gaze along a curve as they negotiate it, but they also look at other parts of the road, the dashboard, traffic signs and oncoming vehicles. A new study finds that when drivers fix their gaze on specific targets placed strategically along a curve, their steering is smoother and more stable than it is in normal conditions. The study, "Driving...

MADRID, Spain (AP) - The Poincare conjecture involves topology, a branch of math that studies shapes. It essentially says that in three dimensions you cannot transform a doughnut shape into a sphere without ripping it, although any shape without a hole can be stretched or shrunk into a sphere. There is a catch: the space has to be finite. Imagine an ant crawling on an apple in a straight line. It can only walk so far before it's back where it started. Even though the apple has three...

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Geodesic -- In mathematics and specifically in differential geometry, a geodesic is a path that furnishes shortest paths between any points on it that are close enough together. The most familiar examples are the straight lines in Euclidean geometry. In more general spaces the geodesics can be more complicated, but one often still thinks of them as "straight" in a sense. On a sphere, for instance, the geodesics are the great circles. The shortest path from point A to point B on a...
