Henry Billingsley is the first person to publish an English translation of #Euclid's Elements. His work is so unique that he put pop-up 3-dimensional models to explain geometric models and mathematical theorems in 1570.

Mind-Blowing Clock Math: Connect the tips of the hour & minute hands every minute… and this insane 11-lobed flower explodes onto the screen! Who knew your wall clock was secretly drawing perfect geometry?

archivists just discovered the first depiction of a robot in cinema. a 127-yr-old reel gathering dust in a random garage in grand rapids, michigan turned out to be a long-lost film by georges méliès from 1897. this is the first time in over a century this footage is being shown.

In 1913, J. N. Muncey of Jessup, Iowa, discovered that the first 144 odd prime numbers (treating 1 as a prime, as was sometimes done at the time) can be arranged into a magic square. When placed in a 12 × 12 grid in just the right way, every row, every column, and both main diagonals add up to the same number: 4514.

need to find the greatest common divisor of two numbers? just fold them on top of each other until you can't any more!

@jjjyx666 Thank you! Can you let us know your name in English and the country where you live so that we can provide that information in the book?

@dpscher The email has been sent to you.

@jjjyx666 Great. You can send a pdf of the diagrams to origami.usa.pub@gmail.com.

@dpscher No problem. ^ ^

Color, clarity, and geometry. An interactive version of Byrne’s The Elements of Euclid (1847) is now online—and beautiful. c82.net/euclid/

@kiyoto645 Thank you! I just sent you an email with more information.

@dpscher Thank you! I’ve sent the PDF to your email. Please let me know if there are any issues.

折り図1冊たまってちょっとした達成感！

@kiyoto645 Great—we are glad that you are interested. The process is simple. You can send your pdf to origami.usa.pub@gmail.com. We will then be in touch with more information.

@dpscher Yes. I'd love for many people to fold my works. Is there somewhere I should apply?

TILED ART es una maravillosa web que muestra las TESELACIONES de numerosos artistas, y os enseña a crear las vuestras con algo (mucho) de geometría. Como si fuérais el mismísimo Escher. tiled.art/en/home/?id=Ki…

@xiaowei1150659 Impressive! Would you be interested in publishing any of your works in the OrigamiUSA Collection--a book we publish each year with models from designers around the world. As a thank you, you would receive a free PDF of the book when it is published this June.

A summary of some works in 2025 and following up on some origami tutorials that might appear in my personal portfolio in the future.
