Mathematical Paper Folding: An Interview with Robert Lang By Margaret Wertheim

http://theiff.org/oexhibits/paper02.html

Robert Lang is a pioneer in the emerging field of computational origami, a branch of mathematics that explores the formal properties and potentialities of folded paper. Like the study of knots, pioneered in the late nineteenth century, computational origami and its practical offshoot origami sekkei or “technical folding” turn out to have a surprising range of applications to real world problems; from working out how to fold up stents so they can be threaded into arteries, to designing thin-film telescopes that are packed into the hold of a space shuttle. Lang is the inventor of the TreeMaker computer program, which allows him to design and calculate crease patterns for a wide range of origami models—including intricate insects, crustaceans, and amphibians. He has been one of the very few Western columnists for the Japan Origami Academic Society and is the author of eight books, including Origami Design Secrets: Mathematical Methods for an Ancient Art. Lang received a doctorate in physics from Caltech and spent twenty years as a laser physicist before becoming a fulltime paper folder.

The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544)

http://robotsquare.com/2013/11/25/difference-between-ev3-home-edition-and-education-ev3/ This article covers the difference between the LEGO MINDSTORMS EV3 Home Edition and LEGO MINDSTORMS Education EV3 products. Other articles in the ‘difference between’ series: * The difference and compatibility between EV3 and NXT ( link ) * The difference between NXT Home Edition and NXT Education products ( link ) One robotics platform, two targets The LEGO MINDSTORMS EV3 robotics platform has been developed for two different target audiences. We have home users (children and hobbyists) and educational users (students and teachers). LEGO has designed a base set for each group, as well as several add on sets. There isn’t a clear line between home users and educational users, though. It’s fine to use the Education set at home, and it’s fine to use the Home Edition set at school. This article aims to clarify the differences between the two product lines so you can decide which

Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide)

https://blog.strcpy.info/2016/04/21/building-a-portable-gsm-bts-using-bladerf-raspberry-and-yatebts-the-definitive-guide/ Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide) I was always amazed when I read articles published by some hackers related to GSM technology. H owever , playing with GSM technologies was not cheap until the arrival of Software Defined Radios (SDRs), besides not being something easy to be implemented. A fter reading various articles related to GSM BTS, I noticed that there were a lot of inconsistent and or incomplete information related to the topic. From this, I decided to write this article, detailing and describing step by step the building process of a portable and operational GSM BTS. Before starting with the “hands on”, I would like to thank all the pioneering Hackers and Researchers who started the studies related to previously closed GSM technology. In particul
