To start calculations, we choose the distributions of the initial binary parameters: the mass of the primary ZAMS component, , binary mass ratio, , orbital separation a . ... whereas the mass ratio distribution is not. ... The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

The Universe was not concentrated into a point at the time of the Big Bang. But the observable Universe was concentrated into a point. The distinction between the whole Universe and the part of it that we can see is important. ... If we go to smaller and smaller times since the Big Bang, the green circle shrinks to a point, but the 78 billion light year box is always full, and it is always an infinitesimal fraction of the infinite Universe. ...

A knowledge of mathematical methods is important for an increasing number of university and college courses, particularly in physics, engineering and chemistry, but also in more general science. ... We have therefore decided to write a textbook that assumes knowledge only of material that can be expected to be familiar to all the current generation of students starting physical science courses at university. ... The general aim of the book is to present a topic in three stages. ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

It is possible to incorporate in the SAS software packages that are not part of the official SAS distribution. These we call 'external packages'. All that is needed is to set the environment variable SAS_PATH to point to all directories that contain SAS components, in the form of a colon-separated list. ...

Local galaxies are in a state of energy equipartition which means that the kinetic energy density equals roughly the thermal one and the magnetic one. ... In models of young galaxies magnetic fields are usually not considered as they are assumed not to be dynamical important at high redshifts. In the presence of turbulence, however, the turbulent dynamo can amplify weak magnetic seed fields by randomly stretching, twisting, and folding the field lines. ...
