Feinerman [2] and Trachtenberg [3] investigated the fairness of a simplified model of dreidel. Zeilberger [4] conjectured that the expected number of spins in a game of dreidel between two players starting with n tokens each is O(n2). Later, Banderier [1] conjectured that even in a multi-player game, the expected number of spins before one of the players goes home is O(n2). We show that the exp...
متن کاملPhoton and electron spins.
It is easy to draw an intuitive parallel between the classical free electromagnetic field and its corresponding quantum, the photon-a spin-1 object. The situation with a massive particle such as an electron is less clear, as a real-world analog of the classical field whose quantum is the massive particle is not available. It is concluded that the fermion particle perspective provides the best a...
متن کاملTail spins
comment on essays from students in other countries, and — worst of all — provide information for incessant bureaucratic enquiries that should not be taking place at all. Non-compliance is rapidly followed by a further enquiry or a thinly veiled reprimand for being forgetful or hurtful or not attending to emails. It is madness. Is science organised effectively? Science can be pricey and the publ...
متن کاملMassless Higher Spins and Holography
We treat free large N superconformal field theories as holographic duals of higher spin (HS) gauge theories expanded around AdS spacetime with radius R. The HS gauge theories contain massless and light massive AdS fields. The HS current correlators are written in a crossing symmetric form including only exchange of other HS currents. This and other arguments point to the existence of a consiste...
متن کاملStringing Spins and Spinning Strings
We apply recently developed integrable spin chain and dilatation operator techniques in order to compute the planar one-loop anomalous dimensions for certain operators containing a large number of scalar fields in N = 4 Super Yang-Mills. The first set of operators, belonging to the SO(6) representations [J, L − 2J, J ], interpolate smoothly between the BMN case of two impurities (J = 2) and the...
