In the night sky are all kinds of stars, and orbiting those stars are planets like the ones in our own solar system. Could those planets have life like we do on Earth? Planet Earth is not too big, not too small, not too hot, and not too cold. It’s just right. Our very own Goldilocks planet . . . .

Goal Structuring Notation (GSN) is becoming increasing popular; practitioners use it in the railway, air traffic management and nuclear industries, amongst others. Originally developed to present safety assurance arguments, GSN need not be restricted to safety assurances only; in principle, you can use it to present (and test) any argument. Anyone wishing to support, or refute, a claim can use GSN. Written by an experienced practitioner, The Goal Structuring Notation is both for those who wish to prepare and present compelling arguments using the notation, and for those who wish to review such arguments critically and effectively. To emphasise the versatility of this approach The Goal Structuring Notation presents examples and questions based on diverse subject areas including Business Management, Drama, Engineering, Politics and Astrobiology. Simple examples introduce each symbol of the notation before introducing more complex structures which illustrate how the symbols work together in practical scenarios. To aid learning, questions and problems augment the text, so that the reader may reflect upon and try out the new concepts and principles presented. As a comprehensive instruction in the basics of GSN and it’s application, The Goal Structuring Notation also serves as a references or manual for the practitioner to dip into as problems are encountered or as a key resource for engineers working in those industries which require a clear description of the notation, covering the initial principles and showing why each piece of the notation is necessary. Originally developed to present safety assurance arguments, GSN need not be so restricted. GSN - The Goal Structuring Notation presents examples from diverse subject areas, including business management, drama, engineering, politics and astrobiology.

Every day thousands of scientists search the universe for living extraterrestrials in fantastic settings from the methane seas of Saturn's moon to planets in the Libra constellation. The Search for Extraterrestrial Life explores the cutting edge theories, NASA missions, and deep space exploration in the pursuit of alien microbes and sentient beings.

Do aliens exist? Are UFOs real? The race is on to discover alien life in this perfect gift for kids who love space. This book will sort myth from fact to bring you the real science behind the search for alien lifeforms. Space expert Joalda Morancy will take readers on a tour of the solar system (and beyond) on board new NASA missions searching for the most likely alien hiding places—from icy moons of Jupiter to the clouds of Venus. Along the way kids will find out about: • The robots sent to Mars to look for Martians • What really goes on at Area 51 • Ways to spot an advanced alien civilization (hint—look for dim stars) In this book beautifully illustrated by Amy Grimes, readers will explore a comet, race futuristic spaceships, and discuss what we would say to aliens when we finally meet them (after “hello!”). They may seem as fanciful as wizards and monsters, but this book will show that scientists not only believe that aliens exist—but that it’s only a matter of time before we find them.
