Geometric Design with PowerPoint!

The geometric design targeted in this book is the combination of polygons itself. The combination of polygons can be made infinitely, but the degree of freedom in design is limited by geometric constraints. I wondered if I could design more freely and could find a way to do it. It is to do an internal dividing into a polygon. And by extending the internal dividing from geometric to design, we were able to find a way to dramatically increase the degree of freedom in design.

With this book, you can create an original pattern by applying the basic knowledge of geometry. Even those who are not interested in geometry can learn the basic knowledge of geometry and the properties of polygons while reading this book, and I wrote it so that it can be used for creating original patterns.

Then, I will explain how to use PowerPoint to create original patterns, and I will also make it possible to download PowerPoint file for creating original patterns for free, so please try it. By providing the PowerPoint file, I am proud that I was able to provide not only the methodology but also the tools for actually using it to many people in the environment where PowerPoint can be used. Please take advantage of it.

Operations Research with Mathematica


In this book, I explain the basic theory and calculation programs for using various operations research (OR) techniques with Mathematica.

This book not only gives you a general view of OR, but also allows you to use your notebook to perform actual calculations. Therefore, it can be used for calculation of various university subjects and graduation research, so if you are in an environment where you can use Mathematica at a university, I would like you to use it. I also believe that it will be the basis for those who are aiming for a Master of Business Administration (MB A) and those who perform big data analysis.

I have confirmed the operation with Mathematica Ver.12.

Creating Math Art with Mathematica

Summary: This book, which was published by the Tokyo Denki University Press in 1997, has been made compatible with Mathematica Ver.12, and the content has been further revised. For example, the cover of this book is my work of the same name with the image of diamond dust. Not only the creation program of this work, but also the extraction to an external file and the handling by illustrator are explained concretely. You can also download the programs (notebooks)  on the website.

Quilt design evolving in geometry

Description: Starting with tiling about the good affinity between patchwork quilts and geometry, we explain the creation of original designs using internal division.In addition to the internal division from Part 4, it explains that the range of design is expanded further by the use of hierarchy.Published in 2019 by Kindle DP and Rakuten Kobo.
