Hi, this is Wayne again with a topic “Book Preview: Make Geometry”.
Welcome to our introduction to our book, make geometry hi, i’m joan horvath and i’m a rocket scientist and i’m rich cameron, a hardware hacker and 3d printer engineer: we’ve written eight books together, but we’re really excited about our latest one make geometry: let’s check out some of The cool projects in the book, most of which have an associated 3d print you can make you – can use them to learn on your own or if you’re, a teacher, we’ve suggested common core standards. They might illustrate all of our 3d printable. Models are open source and you can share them freely from our repository they’re written in the openscad cad program. So you can change them and learn some coding too. Along the way. For example, you can learn about the biggest circle that’ll fit inside a triangle and the biggest triangle that’ll fit inside a circle and see how they’re related or you can learn about how the diagonal of a cube is longer than its side. You can prove the angles of any triangle, add up to 180 degrees and we’ll show you some flat surfaces called nets that you can fold up to make a 3d shape. Some of the earliest uses of geometry were to understand how to relate time, latitude and longitude. We’Ll show you how to figure out where you are on earth, with just a clock and a few observations, we’ll even show you how to use openscad to create arches and castles, so you can 3d print your own medieval fortress. We hope you’re as excited about the book, as we are order yours soon and start exploring with us. .
