Centrifugal force in Kerr geometry
We have obtained the correct expression for the centrifugal force acting on a particle at the equatorial circumference of a rotating body in the locally non-rotating frame of the Kerr geometry. Using this expression for the equilibrium of an element on the surface of a slowly rotating Maclaurin spheroid, we obtain the expression for the ellipticity (as discussed earlier by Abramowicz and Miller...

I'm worried about my paper. " I had a 25-page seminar paper due in less than two weeks. I'd turned in an eight-page proposal, with an outline and an annotated bibliography, and it had been severely and accurately critiqued by the class the day before. It's spring semester, my first year in graduate school at Indiana University. I'd considered myself a poet—I was getting a Masters in Fine Arts—b...

Qing Zou asked me to contribute some remarks introductory to the book that follows. I have not read it. I have indeed only seen a relatively small number of pages. Moreover, although in the course of my career as a mathematician and, in general, in the course of my life, I have acquired a working knowledge of several languages, Chinese in any of its forms is not one of them. Consequently I have...

For [contemporary] social anthropologists, the important conclusion, always worth repeating, is that the observation and the labelling of 'behaviour' are inseparable from the importation of socially derived meanings even when observing monkeys. How much more so when the process is reflexive, when the observers and the observed are both 'meaning-makers' ... Edwin Ardener, 1977: Comprehending Oth...
متن کامل”Centrifugal force: A gedanken experiment”—new surprises
A recently proposed gedanken experiment [G.Z. Machabeli and A.D. Rogava. Phys. Rev. A 50, 98 (1994)], exhibiting surprising behavior, is reexamined. A description of this behavior in terms of the laboratory inertial frame is presented, avoiding uncertainties arising due to a definition of a centrifugal force in relativity. The surprising analogy with the radial geodesic motion in Schwarzschild ...
