Dois Gregos, uma Colaboração, e Ethernet no Arduino

Um dos mais famosos Livros da Antiguidade, "O Método", de Arquimedes, que se pensava perdido, veio à tona, em grande parte, o que é uma grande, e grata, novidade para todos os Matemáticos e Engenhocas em geral... 
Não é que ele esteve prestes a criar o Cálculo Infinitesimal, todos esses anos antes de Newton?
Eis a história atribulada da sua descoberta, neste Documentário:

E mais esta página na Wikipédia, bem mais informativa, e ainda vem com um Puzzle:

Archimedes Palimpsest

From Wikipedia, the free encyclopedia
The Archimedes Palimpsest is a palimpsest (ancient overwritten manuscript) on parchment in the form of a codex (hand-written bound book, as opposed to a scroll). It originally was a 10th-century Byzantine copy of an otherwise unknown work of the ancient mathematician, physicist, and engineer Archimedes (c. 287 BC–c. 212 BC) of Syracuse and other authors, which was overwritten by forgers in the early 20th Century with religious text and images.[1] The manuscript currently belongs to an American private collector.

Ostomachion is a dissection puzzle in the Archimedes Palimpsest (shown after Suter from a different source; this version must be stretched to twice the width to conform to the Palimpsest)


...Passando a um outro Grego da Antiguidade, eis Pitágoras, e o seu famoso copo! Este podem vocês também fazer, neste maravilhoso Instructable da nossa amiga, BrittLiv:

Pythagorean Cup 
In this instructable I'm going to show you a simple way to make a Pythagorean cup. If you are looking for a cool peace of science, or would like to prank your friends, you came to the right place.

The special thing about this cup is that it can be used as a normal drinking cup as long as it is only filled with a certain amount of fluid. If a person is to greedy thought and fills it up to much, the entire content will empty through a hole in the bottom of the cup. It is named after the famous Ionian Greek philosopher Pythagoras of Samos (b. about 570 – d. about 495 BC), you might know him from the Pythagorean Theorem. I did a bit of research and found just as many sources saying that he did invent the cup, as ones saying that say he didn't.


Querem ser Colaboradores da traceparts?
Eles vão-se meter numa data de coisas novas, numa Comunidade de Criadores 3D...
Podem começar por seguir o link que vos vai levar a um pequeno Inquérito, e vos habilita a Prémios: 

We are creating a new community for people who create in 3D. As part of this new community, we are looking for volunteer staff members to join our team. As part of this team, we will ask you to participate in the definition, testing, launch and operation of the new community. Whether you’re an engineer, designer, artist, 3D printing specialist, or student, we want to hear from you. There's only one requirement: you create stuff using 3D software tools. So take the 5 minute survey; at the end you can enter to win one of 15 Amazon gift certificates worth $50 or €50 You've got nothing to lose... 

Se quizerem que o vosso Aparelhómetro Arduino tenha acesso à Ethernet, ora cá vai, e por menos de 10 Dólares:

Add Ethernet to any Arduino project for less than 10$

So you have a neat Arduino project going on. Wouldn't it be nice to add Internet connectivity and do it on the cheap as well? This Instructable will show you how to add Internet connectivity in the form of an Ethernet interface for a few dollars and in less than half an  hour. More info at:
