Leading the game, losing the competition: identifying leaders and followers in a repeated game
(PLoS One, 2016)
We explore a new method for identifying leaders and followers, LF, in repeated games by analyzing an experimental, repeated (50 rounds) game where Row player shifts the payoff between small and large values – a type of ...
Celebrating the centenary of the Schwarzschild solutions
(American Association of Physics Teachers, 2016)
This article is a celebration of the centenary of Schwarzschild’s presentations of his external and internal solutions describing spacetime outside and inside an incompressible, spherically symmetric body. I ...
A solution of the Mitra Paradox
The “Mitra paradox” refers to the fact that while the de Sitter spacetime appears non-static in a freely falling reference frame, it looks static with reference to a fixed reference frame. The coordinate-independent nature ...
I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index ns and the tensor-to-scalar ratio r. The first thing ...
An interesting consequence of the general principle of relativity
(EDP Sciences, 2016-04-12)
We show that Einstein s general theory of relativity, together with the a ssumption that the prin- ciple of relativity encompasses rotational motion, predicts that in a flat Friedmann-Lemaitre-Robertson- Walker (FLRW) ...
A relativistic trolley paradox
(American Association of Physics Teachers, 2016-02)
We present an apparent paradox within the special theory of relativity, involving a trolley with relativistic velocity and its rolling wheels. Two solutions are given, both making clear the physical reality of the Lorentz ...
