The World in Eleven Dimensions: a Tribute to Oskar Klein
Current attempts to find a unified theory that would reconcile Einstein’s General Relativity and Quantum Mechanics, and explain all known physical phenomena, invoke the Kaluza-Klein idea of extra spacetime dimensions. The best candidate is M-theory, which lives in eleven dimensions, the maximum allowed by supersymmetry of the elementary particles. We give a non-technical account. An Appendix pr...
متن کاملOskar Klein , the sixth dimension and the strength of a magnetic pole
It is well known that the world lines of charged particles in the presence of gravitational and electromagnetic fields can be viewed as geodesics in the 5D space-time first proposed by T. Kaluza [1]. Kaluza’s treatment was later improved by Klein in 1926 [2], in a quantum theoretical approach, giving rise to the so-called Kaluza-Klein theorety [4]. This formalism also makes possible to propose,...

متن کاملLocalization of oskar RNA regulates oskar translation and requires Oskar protein.
The site of oskar RNA and protein localization within the oocyte determines where in the embryo primordial germ cells form and where the abdomen develops. Initiation of oskar RNA localization requires the activity of several genes. We show that ovaries mutant for any of these genes lack Oskar protein. Using various transgenic constructs we have determined that sequences required for oskar RNA l...
متن کاملKarl Oskar Illmensee (1939?)
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....
