The Dependence of Galaxy Formation on Cosmological Parameters: Can we distinguish the WMAP1 and WMAP3 Parameter Sets?

 Comment: Galaxy formation (SAM model) permits so many free params, so not so good a tool to constrain cosmology.
The higher z data needs less input from the SAM model, maybe ,so better constain.

The Meaning of Dimensions

Authors:
Paul S. Wesson

Abstract: We review the current status of dimensions, as the result of a long and
controversial history that includes input from philosophy and physics. Our
conclusion is that they are subjective but essential concepts which provide a
kind of book-keeping device, their number increasing as required by advances in
