One service mathematics has rendered the 'Et moi, ..., si j'avait su comment en revenir, je n'y serais point aile.' human race. It has put common sense back Jules Verne where it belongs, on the topmost shelf next to the dusty canister labelled 'discarded n- sense'. The series is divergent; therefore we may be able to do something with it. Eric T. Bell O. Heaviside Matht"natics is a tool for thought. A highly necessary tool in a world where both feedback and non linearities abound. Similarly, all kinds of parts of mathematics seNe as tools for other parts and for other sciences. Applying a...

Although the works of Francis Hutcheson are unfamiliar to most students of philosophy, it cannot be said that he has been entirely ignored. To be sure, most of the recent writers who deal with Hutcheson's philosophy do so in the course of writing about Hutcheson's famous contemporary, David Hume. This is true, for example, of Norman Kemp Smith, whose book entitled The Philosophy of David Hume 1 includes much detailed information concerning Hume's indebtedness to Hutcheson. But others have written about Hutcheson on his own account. William R. Scott's Francis Hutcheson,2 although mainly...

Gui 11 aume Postel was undoubtedly one of the most remarkab 1 e and interesting scholars and thinkers of the sixteenth century. His know ledge of Hebrew and Arabic was rare among his contemporaries, as was his study and use of the Rabbinical, Cabalistic and Islamic literature pre served in these languages. His attempt to harmonize Christian, Jewish and Mbhammedan thought give him an important place in the history of re ligious tolerance, whereas his prophecies about a universal religion and a universal monarchy seem to anticipate more recent ideas of a world state and of general peace. In his...

The 1977 BTE Report on Cost Recovery in Australian Transport 1974-75 provided estimates of the aggregate level of financial cos recovery in the various modes, by broad transport task. It suggested that there were substantial differences between modes in the level of cost recovery. The 1979 Transport Pricing and Cost Recovery seminar concluded that economic efficiency objectives required more attention 1n transport pricing and investment decisions than had been apparent in the past. The principles for economically efficient pricing were spelt out, and several specific issues were identified,...

Plant reproductive biology has undergone a revolution during the past five years, with the cloning, sequencing and localization of the genes important in reproduction. These advantages in plant molecular biology have led to exciting applications in plant biotechnology, including the genetic engineering of male sterility and other reproductive processes. This book presents an interesting and contemporary account of these new developments from the scientists in whose laboratories they have been made. The chapters focus on two areas: the molecular biology of self-incompatibility, which is the...
