A comprehensive reference and history book on what is measured and why. Measurement is one of humankind's oldest and most vital activities. By measuring height, speed, size, temperature, strength and many other factors, humans can compare, improve and progress. In fact, measurement is an essential tool for survival. A Measure of Everything is a wide-ranging and comprehensive guide to what is measured and why. The book begins when the basic measurements were as simple as more, less and enough. As societies evolved, relative measurements were no longer sufficient. Advances in language allowed more precise measurements. Short distances were measured in relation to parts of the human body. For example, the ancient measurement cubit was the length of a pharaoh's arm plus the width of his hand. As society and culture progress and change, so do measurements. The rise of astronomy and the sciences demanded more exact measurements. These measurements are typically named after the discovering scientist, e.g., henry, curie, watt, rutherford, fahrenheit. This book features 28 categories organized into three sections: Earth and Life Sciences: astronomy, distance, time, meteorology, medicine, and five others. Physical Sciences: chemistry, mathematics, physics, speed, weight, temperature, and three others. Technology and Leisure: computers, engineering, finance, food, textiles, and four others. A Measure of Everything is an informative and entertaining book that will appeal to a wide range of readers.
For seven years, Paul Lockhart’s A Mathematician’s Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of K–12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done. Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living. In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science. Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can “do the math” in a way that brings emotional and aesthetic rewards. Measurement is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work.
There are millions of things to measure . . . and almost as many ways to measure them! Marvelosissimo the Mathematical Magician is back -- and ready to explore the invention of length, weight, and volume measurements. After that, with another wave of his wand, the wizard introduces the world of metrics and makes it easy to understand the basic pattern of meters, liters, and grams. With Steven Kellogg's playful and delightfully detailed illustrations, measuring has never been such a blast!
Children learn how to measure everything including length, weight, volume, temperature, and time through pop-ups and flaps in this fun and educational activity book. There's even a life-size ruler on the jacket! Measuring is a key maths topic for early learners, and this book supports KS1 concepts. This bold and bright book helps kids understand the language and maths of measuring. Fun and simple lift-the-flap puzzles help kids to relate measuring to everyday life - from measuring lengths of pencils with a ruler to weighing fruit on scales. Other activities include a wheel with a clock face to help kids learn to tell the time. How to Measure Everything concludes with a colourful bedroom picture with a quiz that gets you to measure and compare lots of things in the scene. How to Measure Everything engages with a key maths topic in a new, interactive, and playful way.
The first volume of The Handbook of Humidity Measurement focuses on the review of devices based on optical principles of measurement such as optical UV, fluorescence hygrometers, optical and fiber-optic sensors of various types. Numerous methods for monitoring the atmosphere have been developed in recent years, based on measuring the absorption of electromagnetic field in different spectral ranges. These methods, covering the optical (FTIR and Lidar techniques), as well as a microwave and THz ranges are discussed in detail in this volume. The role of humidity-sensitive materials in optical and fiber-optic sensors is also detailed. This volume describes the reasons for controlling the humidity, features of water and water vapors, and units used for humidity measurement.
