Kids, don't try this at home. Or anyone else. Even if you're not a kid.)

Mathematics is beautiful--and it can be fun and exciting as well as practical. Good Math is your guide to some of the most intriguing topics from two thousand years of mathematics: from Egyptian fractions to Turing machines; from the real meaning of numbers to proof trees, group symmetry, and mechanical computation. If you've ever wondered what lay beyond the proofs you struggled to complete in high school geometry, or what limits the capabilities of computer on your desk, this is the book for you. Why do Roman numerals persist? How do we know that some infinities are larger than others? And how can we know for certain a program will ever finish? In this fast-paced tour of modern and not-so-modern math, computer scientist Mark Chu-Carroll explores some of the greatest breakthroughs and disappointments of more than two thousand years of mathematical thought. There is joy and beauty in mathematics, and in more than two dozen essays drawn from his popular "Good Math" blog, you'll find concepts, proofs, and examples that are often surprising, counterintuitive, or just plain weird. Mark begins his journey with the basics of numbers, with an entertaining trip through the integers and the natural, rational, irrational, and transcendental numbers. The voyage continues with a look at some of the oddest numbers in mathematics, including zero, the golden ratio, imaginary numbers, Roman numerals, and Egyptian and continuing fractions. After a deep dive into modern logic, including an introduction to linear logic and the logic-savvy Prolog language, the trip concludes with a tour of modern set theory and the advances and paradoxes of modern mechanical computing. If your high school or college math courses left you grasping for the inner meaning behind the numbers, Mark's book will both entertain and enlighten you.

All of the clocks at the amusement park have roman numerals instead of numbers. Young readers will learn how Abby and Ben figure out how to read roman numerals as well as the order of the rides they want to go on--first, second, and third.

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 Many parents are frustrated by the school system, perhaps because of bullying, crowded classrooms, and outdated, dull, online courses.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.
