Moving Lights - Acceleration

Late time acceleration in a slow moving galileon field

In this paper, we examine the cosmological viability of a slow moving galileon field in a potential. The Lagrangian L = − 1 2 gπ;μπ;ν + G 2M2 π;μπ;ν respects the galileon symmetry in curved space time. We carry out detailed investigations of the underlying dynamics of this Lagrangian with Einstein-Hilbert term and a potential. We demonstrate that the model can give rise to a viable ghost free l...

Gravitational Acceleration of a Moving Object at the Earth’s Surface

Einstein deduced (very briefly on p. 834 of [1], and in slightly more detail on pp. 820-822 of [2]) that the gravitational deflection of light according to general relativity is twice the “Newtonian” value. Einstein did not deduce the acceleration of light (or that of other fastmoving particles), which has perhaps left the impression that the acceleration at the surface of the Earth is no diffe...

Arbour lights

Amongst the theoreticians there was a subspecies who interacted with experimentalists — these theorists tried to make sure that their ideas were testable and that someone tested them. Preeminent amongst these was Francis Crick who wrote all the quotes above shown in red italics (taken from Crick’s autobiographical book What Mad Pursuit: A Personal View of Scientific Discovery; Basic Books, New ...

Bezier Lights

In this paper we introduce Bezier Lights, an intelligent lighting system that allows users to intuitively establish virtual boundaries in indoor environments. Boundaries can be easily created/modified by arranging the layouts of disk-shaped devices (“stones”) on the building floor. The immediate purpose of the system is to assist users in incorporating location-aware capabilities into private p...
