Book Review Essay Can a Biosphere be Selfish?: The Gaian Challenge to Darwinism1 by Charles H. Lineweaver2 Scientists Debate Gaia: The Next Century, edt. ... Since then Lovelock has written copiously and articulately on Gaia both in books of popular science (Lovelock 1990, 2000a,b, 2001) and in professional literature. ... The Gaian Science in the chapters of this book poses that challenge by asking again and again: Did the biosphere evolve to regulate the Earth? ґ and if it did, how did it do it? ...

The sample covers a substantial range in maximum rotation velocity and depro jected face-on surface brightness, and contains seven spirals with either a boxyor peanut-shaped bulge. ... From the photometry we find that intrinsically more flattened discs tend to have a lower face-on central surface brightness and a larger dynamical mass-to-light ratio. ...

... This example explores the evolution of the sun. ... Given that the mass of proton is 1.00870 atomic mass units and the mass of a helium nucleus is 4.0026 atomic mass units, estimate the sun's average rate of energy production by nuclear reactions (in solar luminosities) over its lifetime. Take the age of the sun as 4.5 в 109 yr. Does nuclear energy production seem to successfully account for the energy output of the sun? (b) Comment on the changes in the abundance profiles as the sun ages. ...

... The most notable is due to the unknown value of the stellar mass-to-light ratio (the disk-halo degeneracy); even with this known, degeneracies between the halo parameters themselves may prevent an unambiguous determination of the shape of the dark halo profile, which includes the inner density slope of the dark matter halo. ... We explore constraints on the disk and halo parameters and apply these to four mock and six observed disk galaxies with high resolution and extended rotation curves. ...

... Because of the low conductivity, the magnetic coupling is weak and depends critically on density, temperature, ionisation rate and charged species. ... Implications When the Hall regime dominates near the midplane and ambipolar diffusion is dominant closer to the surface, a thicker layer of the disc is unstable to MRI perturbations and modes grow faster than under the ambipolar diffusion approximation. ... Right panel: For weak coupling, Hall limit perturbations grow until vA/cs ~ 2.9. ...
