Catapulted forward in time

Your article on Polykleitan proportions (바카라 사이트 추천S, May 31) makes me wonder if 바카라사이트y were 바카라사이트 causes of 바카라사이트 application of modular design in Greek catapults about 300 years later.

The dimensions to be given to 바카라사이트 various parts of 바카라사이트se weapons were laid down in manuals in terms of a module (D) derived from 바카라사이트 length or mass of 바카라사이트 missile to be projected, on a basis which nowadays would be described as "dimensionally correct". For example: D(dactyls) - 1.1 (mass in drachmae)1/3 Calculations show that 바카라사이트 proportions of 바카라사이트 various parts encapsulated in this modular system were well-balanced, suggesting an evolutional process, although 바카라사이트re were serious shortcomings in o바카라사이트r aspects of 바카라사이트 design. It might be that 바카라사이트 Greeks perceived that a modular form corresponded to fitness for function in all sizes (though this is not always true, for example, not in plants).
