Book Description
From terrorist attacks to big money jackpots, Struck by Lightning deconstructs the odds and oddities of chance, examining both the relevant and irreverent role of randomness in our everyday lives. Human beings have long been both fascinated and appalled by randomness. On the one hand, we love the thrill of a surprise party, the unpredictability of a budding romance, or the freedom of not knowing what tomorrow will bring. We are inexplicably delighted by strange coincidences and striking similarities. But we also hate uncertainty's dark side. From cancer to SARS, diseases strike with no apparent pattern. Terrorists attack, airplanes crash, bridges collapse, and we never know if we'll be that one in a million statistic. We are all constantly faced with situations and choices that involve randomness and uncertainty. A basic understanding of the rules of probability theory, applied to real-life circumstances, can help us to make sense of these situations, to avoid unnecessary fear, to seize the opportunities that randomness presents to us, and to actually enjoy the uncertainties we face. The reality is that when it comes to randomness, you can run, but you can't hide. So many aspects of our lives are governed by events that are simply not in our control. In this entertaining yet sophisticated look at the world of probabilities, author Jeffrey Rosenthal-an improbably talented math professor-explains the mechanics of randomness and teaches us how to develop an informed perspective on probability.

Book Description
School is one option for education; homeschooling is the second, and unschooling is the third. Many parents are frustrated by the school system, perhaps because of bullying, crowded classrooms, and outdated, dull, online courses. Disengaged learners that have no say in their coerced curriculum tend to act out, tune out, or drop out. Education must change and unschooling is the fastest-growing alternative method of learning. Two decades ago, students registered with their local school based on their house address. Now, with the internet, students are borderless. Learning can occur anywhere, anytime, anyway and from anyone-including self-taught. Self-directing their education, unschoolers learn through: - Play - Projects - Reading - Volunteering - Video games - Sports - Mentorship - Travel - Life This book explores the path of 30 unschooled children who self-directed all or part of their education and were accepted by universities, colleges, and other postsecondary schools. Most have already graduated. What children need most are close relationships-parents, teachers, siblings, relatives, coaches, and mentors within a wider community, not just within an institutional school. Educational content is everywhere. Caring relationships are not. Families that embrace unschooling, do not have to choose between a quality education and a relaxed, connected family lifestyle. They can have both.
