doomsday around the corner ? ”
We make corrections on the paper by González-D ´ iaz [Phys. Lett. B 586 (2004) 1] where the false illustration of Eq. (10) for the case of β = 0.5 (relevant to Fig. 1 (II) therein is pointed out and illustrated.
متن کاملForecasting cosmic doomsday from CMB-LSS cross-correlations
A broad class of dark energy models, which have been proposed in attempts at solving the cosmological constant problems, predict a late time variation of the equation of state with redshift. The variation occurs as a scalar field picks up speed on its way to negative values of the potential. The negative potential energy eventually turns the expansion into contraction and the local universe und...

This chapter introduces the Random Modulation Pre-Integrator (RMPI) and details the status of an integrated circuit implementing the architecture. To our knowledge, this is the first full-speed hardware RMPI in existence. The goal of this chapter is to describe some key parameters of the RMPI that are essential to its performance. This is not a hardware chapter and does not go into detail of th...
متن کاملDoomsday Book, Vol. II
For humans, power is in part control over their lives. History is a collection of past experiences that empower informed actions. A repertoire is the catalog of your things. A large diverse repertoire can be critical or it can be irrelevant. A great hammer is nice if the job involves a nail. You might have lots of wrenches, but not the one that bends the right way for the “tough nut”. The wrong...
متن کاملNotes on "doomsday models".
I would like to state, briefly and bluntly, why I think the various "Doomsday Models" are worthless as science and as guides to public policy. I hope it will not be deduced that I believe the problems of population control, environmental degradation, and resource exhaustion to be unimportant, or that I think an adequate response to them is a vague confidence that something will turn up. They ar...
