This book explores how mathematics appears in everyday life. It presents math in a fun and beautiful way using knowledge at the junior high and high school level. It is written for general readers, not for experts. The book avoids difficult math and instead focuses on how new ways of thinking and careful observation can reveal interesting math ideas. It is divided into 33 topics. These include familiar recreational math like tournament games, magic squares, and math tricks, as well as uniq...

The origami introduced in this book is based on simple techniques. Some were previously known by origami artists and some were discovered by the author. Curved-Folding Origami Design shows a way to explore new area of origami composed of curved folds. Each technique is introduced in a step-by-step fashion, followed by some beautiful artwork examples. A commentary explaining the theory behind the technique is placed at the end of each chapter.Features

Easily Create Origami with Curved Folds and SurfacesOrigami—making shapes only through folding—reveals a fascinating area of geometry woven with a variety of representations. The world of origami has progressed dramatically since the advent of computer programs to perform the necessary computations for origami design.3D Origami Art presents the design methods underlying 3D creations derived from computation. It includes numerous photos and design d...

This book equips readers with the fundamentals of 3DCG that support the advanced technologies. The content of this book is divided into four categories: modeling, rendering, character animation, and physical simulation, and each is explained in a separate chapter. In simpler terms, these four technologies can be described as creating shapes, creating images, creating motion, and reproducing the behavior of the natural world. The "Modeling" chapter describes the theory behind describing the...

Design Techniques for Origami Tessellations is both a collection of origami tessellations and a manual to design them.This book begins by explaining general design methods, the history and definitions of origami tessellations, and the geometric features of flat origami, before moving on to introduce a brand-new design method: the "twist-based design method." This method generates base parts that connect "twist patterns” (that can be folded with a twist) wi...

This book adds remarkable advances in microwave chemistry, methods, equipment, and practical examples since the first edition was published in 2018. Moreover, practical examples of the use of microwave energy have been upgraded. It also includes how to easily predict microwave heating using material constants. In addition, coupling analysis simulation with electromagnetic fields and heat transfer which greatly support researchers' experiments is covered.The principal aim of this bo...

How to Draw Portraits is a unique collection of techniques, terminology, and examples for the beginner and advanced graphite artist. Over one hundred illustrations support carefully reviewed explanations of elemental technique. Discover that you can draw with an eraser and simulate skin texture with circularism. Find out how to draw hair, and how to break down complex shapes into simple abstract components. Use layers and "punch-up" your work. You can even draw with a brush and graphite du...

Modular origami is the latest craze in paper folding!These three-dimensional models are created from a number of small pieces of paper that are easily folded and then cleverly fit together to form a spectacular shape. They range from paper polyhedra to bristling buckyballs that are reminiscent of sea urchins—to ornate flower-like spheres.Each piece of paper is held by the tension of the other papers—demonstrating the remarkable hidden properties of paper, w...

Perspective made simple. How to draw in a realistic style.Perspective is arguably the most important element of drawing and also one of the most difficult to master. It's what gives drawings dimension and is the key to realistic drawing. Now the best-selling authors of Drawing for the Absolute Beginner are here to demystify perspective, simplify concepts such as vanishing points and multi-point perspective, and make it easy for you to experience success......

Drawing is not a talent. It’s a skill anyone can learn. This is the philosophy of drawing instructor Brent Eviston based on his more than twenty years of teaching. He has tested numerous types of drawing instruction from centuries old classical techniques to contemporary practices and designed an approach that combines tried and true techniques with innovative methods of his own. Now, he shares his secrets with this book that provides the most accessible, streamlined, and effective methods...

The microscope is the most important tool in the microbiologists toolbox. Nowadays, several companies sell very well made microscopes, but such a luxury was unknown to the earliest microbiologists. They had to build their own microscopes, and many advancements to the science of microbiology were made by people who managed to improve on their own private microscopes.While basic models have become increasingly affordable in recent years, purchasing a digital microscope can still be a ...

"Mechanical Drafting" is a complete and detailed handbook on technical drawing intended for students of engineering and related subjects.
