Happy square root of 10 day!


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 :-(


Your Pi day will come (22/7).


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.

Supposedly, Plato suspected that pi was exactly equal to the sum of the square root of 3 and the square root of 2.


Thank you! Since today is my birthday too... and, finally, someone pointed out *my* approximation :-D




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.



You are correct. I have a Hemmi 250 with the CF and DF scales folded at sqare root of ten.

Interesting. My Posts (made by Hemmi) are folded at Pi.

Hey, guys !

We still have to wait 12 years before the really true square of 10 day !

Or two and nearly two an a halb centuries for the high precision 10 SQR day : 3.16 2278
