Writing scientific papers and giving talks at meetings and conferences are essential parts of research scientists' work, and this short, straightforwardly written book will help workers in all scientific disciplines to present their results effectively. The first chapter is about writing a scientific paper and is a revision of a prize-winning essay. Later chapters discuss the preparation of typescripts, speaking at meetings and writing theses. There are also chapters addressed particularly to those scientists to whom English is a foreign language and to those in North America. The last chapter gives information about dictionaries, style books and other literature. The book draws on the author's wealth of experience in presenting his own work and in editing the work of others, and he draws his examples from a range of subjects.
