Daniel would like you to know that he knows 50 digits of pi. He uses groups of 5:

3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510

This is all he knows and he is going to see how far he can get!

Your shoe size can tell your age?


I. Input shoe size

II. blah

III. blah

IV. blah

V. blah (Arbitrary number that makes this work, but only for the year 2012)

VI. Input age

Output is your shoe size and age. If you input someone else’s values, it outputs their values back. Magic!

11 Magnificent Wonders of the Ice World

Not a math post, but cool nonetheless:


In polar and other cold regions there are ice, snow and water formations that are unusual, unique, and some of them so beautiful to breathtaking. Most of these wonders of nature can be visited only by scientists and rare adventurers who are ready for significant physical and financial exertions. Because of their volatility and locations, these formations can be seen only at certain periods of the year.
