Spinors | Structures on manifolds | Riemannian geometry | Supersymmetry
Killing spinor is a term used in mathematics and physics. By the more narrow definition, commonly used in mathematics, the term Killing spinor indicates those twistorspinors which are also eigenspinors of the Dirac operator. The term is named after Wilhelm Killing. Another equivalent definition is that Killing spinors are the solutions to the Killing equation for a so-called Killing number. More formally: A Killing spinor on a Riemannian spin manifold M is a spinor field which satisfiesfor all tangent vectors X, where is the spinor covariant derivative, is Clifford multiplication and is a constant, called the Killing number of . If then the spinor is called a parallel spinor. In physics, Killing spinors are used in supergravity and superstring theory, in particular for finding solutions which preserve some supersymmetry. They are a special kind of spinor field related to Killing vector fields and Killing tensors. (Wikipedia).

What Kills Us? How We Understand Risk.
One of the things that baffles me about people is how they completely misunderstand risk. Lots of my friends panic about things that have no real chance of killing them, but ignore the things that will. This can lead us to make irrational decisions, and sometimes irrational policy. What re
