Penrose is a master of his field. This text has exercises in it that range from simple expositions to those that will take weeks of serious thought. IPenrose is a master of his field. This text has exercises in it that range from simple expositions to those that will take weeks of serious thought. If you are a student of physics, this text casts the widest net possible, touring you through all of the mathematics and physics that you will become intimately familiar with in connections and expositions that you will rarely find in single courses....more

It is still a pretty good read, although if you have any training in cosmology, you can skip right to the last two chapters for his idea. It is a bit vague in support, but it is an interesting hypothesis....more

Even so, it contains very valuable overview of the glaring flaws in methodology, citation (citing papers that do not support or that even contradict the statement due to different definitions), media interpretation and several examples of unintentional statistical errors that are endemic to gender studies cases. This should be required reading for anyone in these fields. If you are familiar with statistical and experimental design flaws, you may already suspect many of the flaws presented here, but the actual presence of them in the most cited papers in these fields may be surprising....more

This is an excellent layperson's introduction to the mathematics and viewpoints used in the modern approach to classical (non-quantum) mechanics. TheThis is an excellent layperson's introduction to the mathematics and viewpoints used in the modern approach to classical (non-quantum) mechanics. The intent is obviously to pave the way for the next book on quantum mechanics, as they waste no time in going from Newtonian to Lagrangian and Hamiltonian mechanics. There are just a few errata and some hand-waving sentences that would make most mathematicians cringe (ie., the author sometimes conflates smooth functions with analytic ones, and in one instance equated a vanishing second derivative with the presence of a point of inflection), but a visit to the website and some experience with calculus should allow the reader to get past these minor errors. The value of the text is primarily that it is the only one at this time that concisely and entertainingly introduces the layperson to modern mechanics in a fully usable form which emphasizes the practical applications, not merely as a series of anecdotes....more
