11C aspect ratio  Dave Chapman  07272005 Has anyone mentioned that the apsect ratio of the 11C and similar calculators is almost exactly the Golden Ratio, (Sqrt[5]+1)/2 ?
Re: 11C aspect ratio  Howard Owen  07272005 In nature when this shows up, we say it's the result of underlying physical processes that embody the mathematics that produce the ratio. In a calculator designed by HP in Corvalis, we'd have to say it's the result of underlying humor by mathematics geeks embodying the spirit of great engineering. Re: 11C aspect ratio  Vieira, Luiz C. (Brazil)  07272005 Hi, Dave; some time ago, Gerson mentioned this very fact in here. I tried to search the aschives but did not find it. If Gerson read this thread he'll probably remember when did he post it. Sorry not being more precise about the message itself. Best regards.

Re: 11C aspect ratio  Gerson W. Barbosa  07272005 Hi Luiz, I coudn't find the post either. In short, the length/width ratio in the Voyagers is 12.7cm/7.87cm = 1.6137 very close to 1.6180 [Sqrt(5)+1]/2. In inches, 5"/3.1" = 1.6129. These are official specifications listed at: http://www.hp.com/calculators/financial/12c/specs.html Actually, the first one to have mentioned this here was John Ioannidis: http://www.hpmuseum.org/cgisys/cgiwrap/hpmuseum/articles.cgi?read=170 Now we know what the Parthenon and the Voyagers have in common: the golden ration. No wonder they are so wonderful! Cheers, Gerson.
Re: 11C aspect ratio  don wallace  07282005 Hi all. IMHO, it's just (yet) another beautiful touch by the designers to enhance the visual beauty of the product. . .
