(/thread-164555.html) Happy square root of 10 day! - Gene Wright - 03-16-2010 I did not think PI should have all the fun. :-) Re: Happy square root of 10 day! - Maximilian Hohmann - 03-16-2010 Quote:I did not think PI should have all the fun. :-) And why does no one think about us europeans? We get no fun at all, the way we write our dates :-( Re: Happy square root of 10 day! - Namir - 03-16-2010 I remember noticing how close pi and the square of 10 were when I was playing with simple approximations for pi! I bet you are now more aware of these things after visiting locations in Greece where old Greek mathematicians lived.

Re: Happy square root of 10 day! - Crawl - 03-16-2010 Supposedly, Plato suspected that pi was exactly equal to the sum of the square root of 3 and the square root of 2. Re: Happy square root of 10 day! - Massimo Gnerucci (Italy) - 03-16-2010 Thank you! Since today is my birthday too... and, finally, someone pointed out *my* approximation :-DGreetings,Massimo Re: Happy square root of 10 day! - Palmer O. Hanson, Jr. - 03-16-2010 Gene: I am fairly sure that some slide rules were made with the CF scales folded at the square root of ten rather than at pi. I am away from my files for a few days. I will try to verify it next week. Palmer Re: Happy square root of 10 day! - Steve Keeley - 03-17-2010 You are correct. I have a Hemmi 250 with the CF and DF scales folded at sqare root of ten. Re: Happy square root of 10 day! - C.Ret - 03-17-2010 Hey, guys ! We still have to wait 12 years before the really true square of 10 day ! 3.16.22 March, 16th of 2022 ? Or two and nearly two an a halb centuries for the high precision 10 SQR day : 3.16 2278 Re: Happy square root of 10 day! - Martin Pinckney - 03-17-2010 Quote: I have a Hemmi 250 with the CF and DF scales folded at square root of ten. Interesting. My Posts (made by Hemmi) are folded at Pi.
