The question of whether abortion should or should not be permitted, and under what circumstances, is among the most difficult and sometimes anguished decisions for contemporary men and women. How we feel about this issue, and what actions we take, help to define our image of who we are as social beings.In The Facts of Life, Harold Morowitz and James Trefil, two distinguished scientists and science writers, examine what modern biology can contribute to our understanding of this debate. Sensitive to the myriad ethical and religious arguments beyond the realm of science that swirl around abortion, the authors focus on one crucial question--when does a fetus acquire "humanness," that quality that sets us apart from all other living things. From the viewpoint of science, they argue, "humanness" begins with the possession of a highly developed cerebral cortex. While humans are linked via cell structure and cell chemistry with all life on our planet - from monkeys to fruit flies to pumpkins - it is the human brain structure which makes us who we are. Reviewing the latest advances in molecular biology, evolutionary biology, embryology, neurophysiology, and neonatology - fields that all bear on this question - the authors reveal a surprising consensus of scientific opinion on when humanness begins.A lucid primer on the biological aspects of the abortion issue, The Facts of Life is also a fascinating inquiry, across various scientific disciplines, into what makes us uniquely human. Anyone who struggles with the issue of abortion will be grateful to find a work that moves this heated issue from the intensely emotional area it has occupied to the calmer domain of science.

Albert Einstein, one of the most prolific scientists of the twentieth century, developed the theory of relativity which was crucial for the advancement of modern physics. Young Einstein identified a paradox between Newtonian Mechanics and Maxwell’s equations which pointed to a flawed understanding of space and time by the scientists of the day. In Relativity, Einstein presents his findings using a minimal amount of mathematical language, but the text can still be challenging for readers who lack an extensive scientific background.The Routledge Guidebook to Einstein’s Relativity expands on and supplements this seminal text, by exploring: the historical context of Einstein’s work and the background to his breakthroughsdetails of experimental verification of special and general relativitythe enduring legacy of Einstein’s theories and their implications for future scientific breakthroughs.This is an essential introduction for students of physics, philosophy and history in understanding the key elements of the work and the importance of this classic text to society today.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists, Trefil and Summers, bring readers on a marvellous experimental voyage through the possibilities of life - unlike anything we have experienced so far - that could exist on planets outside our own solar system. Life could be out there in many forms: on frozen worlds, living in liquid oceans beneath ice and communicating (and even battling) with bubbles; on super-dense planets, where they would have evolved body types capable of dealing with extreme gravity; on tidally locked planets with one side turned eternally toward a star and, even, on “rogue worlds” which have no star at all. Yet this is no fictional flight of fancy: the authors take what we know about exoplanets and life on our own world and use that data to hypothesise about how, where and which sorts of life might develop. IMAGINED LIFE is a must-have for anyone wanting to learn how the realities of our universe may turn out to be far stranger than fiction.
