I propose to begin my paper on the logic of the social sciences with two theses which formulate the opposition between our knowledge and our ignorance. First thesis: We know a great deal. And we know not only many details of doubtful intellectual interest but also things which are of considerable practical significance and, what is even more important, which provide us with deep theoretical ins...

We provide combinatorial interpretations for determinants which are Fibonacci numbers of several recently introduced Hessenberg matrices. Our arguments make use of the basic definition of the determinant as a signed sum over the symmetric group.

When Karl Deisseroth, a neuroscientist at Stanford University, recently set out to improve a trustymolecular tool for finessing the activity of brain cells in living animals, he had nary a clue that nature had longanticipated his fastidious feat of engineering. Deisseroth, whose name has become nearly metonymous with optogenetics, a molecular technique for manipulating neurons using light, has ...

Karl Oskar Illmensee studied the cloning [2] and reproduction of fruit flies, mice, and humans [3] in the US and Europe during the twentieth and twenty-first centuries. Illmensee used nuclear transfer techniques (cloning [2]) to create early mouse [4] embryos from adult mouse [4] cells, a technique biologists used in later decades to help explain how embryonic cells function during development....

Popper commanded international audiences and conversation with him was an intellectual adventure even if a little rough animated by a myriad of philosophical problems. His intense desire to tear away at the veneer of falsity in pursuit of the truth lead him to contribute to a field of thought encompassing (among others) political theory, quantum mechanics, logic, scientific method and evolution...
