This book describes the subject of electrodynamics at classical as well as quantum level, developed as an interaction at a distance. Thus it has electric charges interacting with one another directly and not through the medium of a field. In general such an interaction travels forward and backward in time symmetrically, thus apparently violating the principle of causality. It turns out, however, that in such a description the cosmological boundary conditions become very important. The theory therefore works only in a cosmology with the right boundary conditions; but when it does work it is free from the divergences that plague a quantum field theory.

Originally published in 1957, this book offers a challenging intellectual experience to the reader who wishes to understand the broad historical trends that determine the future of humanity on this planet. The book examines natural laws that govern humanity by looking at communities over long periods of time and noting patterns which become evident. The book includes discussions of communism, the crisis in food and population growth, the significance of industrialism and man and his religious beliefs – all issues that remain as relevant today as when the book was first published.

The first edition of the monumental book Diseases from Space by Sir Fred Hoyle and N Chandra Wickramasinghe appeared some 40 years ago, encapsulating the key principles of Panspermia, and it has been the guiding principle in the new scientific field of Astrobiology.This latest edition, revised and expanded by Chandra Wickamasinghe, continues to describe the consequences of the theory of cometary panspermia that relate to the origins of epidemic disease. Available data on historic and modern plagues are analysed to show that extraterrestrial bacteria and viruses are the cause of ongoing pandemics of diseases.Adherence to an inappropriate and obsolete theory of pandemics could put in jeopardy the economic well-being of the entire world, perhaps even threatening the continued existence of our civilization.

This text expounds in a logical and scientific manner the idea that life did not originate on earth, but was added to it from the comets. When Fred Hoyle and Chandra Wickramasinghe first made this proposal in the 1970s, they had few takers - because the theory flew in the face of established beliefs. This text argues that in recent years, evidence to support this theory has accumulated from many different directions and grown to the point of being compelling. This work should be of value to readers interested in general science, the origin of man and the meaning of life.

In addition to being the man who coined the term 'the Big Bang', world-renowned astronomer Sir Fred Hoyle also produced a fine body of science fiction. The Andromeda Anthology contains the acclaimed duology A for Andromeda and The Andromeda Breakthrough, co-written with John Elliot.

The close-knit group of scientists who work at the new radio telescope are shocked to receive a mysterious signal from the heart of the Andromeda galaxy. Working with mathematician Christine Jones, Dr John Fleming interprets the signal as the instructions to build a super-computer. When the computer begins to relay the information it receives from Andromeda, scientists find themselves possessing knowledge previously unknown to mankind, knowledge that could threaten the security of human life itself.

In addition to being the man who coined the term 'the Big Bang', world-renowned astronomer Sir Fred Hoyle also produced a fine body of science fiction. This omnibus contains three of his SF novels: Ossian's Ride, October the First Is Too Late & Fifth Planet, co-written with his son, Geoffrey Hoyle. Ossian's Ride: The year is 1970. Sealed behind an impenetrable barrier in the south of Ireland, the Industrial Corporation of Eire startles the rest of the world with its efficiency, its brilliance . . . October the First Is Too Late: Unusual solar activity has played havoc with terrestrial time: England is in the '60's, but in France, it is 1917 and WWI is still raging in western Europe . . . Fifth Planet: Another star is due to pass close to the sun, close enough for conventional spacecraft to reach it. Signs of chlorophyll are detected on one of the worlds, suggesting that it supports life. Rival Soviet and US expeditions are launched to visit it. But what will they find on the 'Fifth Planet'?

A 1959 classic 'hard' science-fiction novel by renowned Cambridge astronomer and cosmologist Fred Hoyle. Tracks the progress of a giant black cloud that comes towards Earth and sits in front of the sun, causing widespread panic and death. A select group of scientists and astronomers - including the dignified Astronomer Royal, the pipe smoking Dr Marlowe and the maverick, eccentric Professor Kingsly - engage in a mad race to understand and communicate with the cloud, battling against trigger happy politicians. In the pacy, engaging style of John Wyndham and John Christopher, with plenty of hard science thrown in to add to the chillingly credible premise (he manages to foretell Artificial Intelligence, Optical Character Recognition and Text-to-Speech converters), Hoyle carries you breathlessly through to its thrilling end.
