What will happen if (perhaps when) humanity makes contact with another civilisation on a different planet?In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilisations to our existence. Of course, we don't know if such civilisations really exist. For the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the sea...

Tilt and shift lenses offer tremendous creative possibilities for users of digital SLR and mirrorless cameras. This practical book explains the techniques that will help you take better photos - photos that don't distort or lose focus. Assessing the benefits and pitfalls of a range of lenses, adapters, software and editing techniques, it guides you through the practicalities of working with these lenses and gives you the skills to use them to best effect. With stunning examples throughout,...

Have you ever wondered what it would be like to watch a double sunset on Tatooine, stand among the sand dunes of Arrakis or gaze at the gas-giant planet Polyphemus from the moon Pandora? In Amazing Worlds of Science Fiction and Science Fact, Keith Cooper explores the fictional planets of films such as Star Wars, Dune and Avatar, and discusses how realistic they are based on our current scientific understanding and astronomical observations. The real exop...

The quest to find a theory of quantum gravity that could potentially explain everything.Nearly 60 years ago, Nobel Prize-winners Arno Penzias and Robert Wilson stumbled across a mysterious hiss of faint radio static that was interfering with their observations. They had found the key to unravelling the story of the Big Bang and the origin of our universe.That signal was the Cosmic Microwave Background (CMB), the earliest light in the univer...

Taking the Mask Off... was a hard book for me to write.What started out as daily journal entries that centered around losses, regrets, family, and the beauty of nature, all written during COVID isolation but covering my entire life's experience were now over 150 handwritten short stories contained in four 5 x 7-inch memorandum books filled in front to back.It took me six months to realize that my writings were more than simple journalling; they were therapy. Therap...

Nearly sixty years ago, Nobel Prize-winners Arno Penzias and Robert Wilson stumbled across a mysterious hiss of faint radio static that was interfering with their astronomical observations. In it, they had found the key to unravelling the story of the Big Bang and the origin of our universe. That signal was the Cosmic Microwave Background (CMB), the earliest light in the universe, released 379,000 years after the Big Bang. It contains secrets about what happened during the very first tiny ...

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.However, the act of transmitting raises troubling questions about the process of ...

The premise of this book is that it is simply impossible to determine, with any degree of confidence, as to whether there is a transcendent, creative being which is responsible for the existence of the universe. Therefore, the conclusion that inevitably flows from this realization is that the most intellectually honest position to espouse is one of agnosticism. A corollary of this idea is that it is also impossible to know if our lives are anything more than a random sequence of events ord...

Where or to whom do you run to when you realize you have made a terrifying, possibly ...

Engineering a Compiler, Third Edition covers the latest developments in compiler technology, with new chapters focusing on semantic elaboration (the problems that arise in generating code from the ad-hoc syntax-directed translation schemes in a generated parser), on runtime support for naming and addressability, and on code shape for expressions, assignments and control-structures. Leading educators and researchers, Keith Cooper and Linda Torczon, have revised this popular text with a fres...

This entirely revised second edition of Engineering a Compiler is full of technical updates and new material covering the latest developments in compiler technology.
