@bartavelle: I am not sure you can run into rounding issues with numbers so small. But feel free to use Python's Decimal package for best results.

But your algorithm makes n squared computations jj. Despite not working because of this awesome grammatical "feature" of Python that is tabulation, newsoft's version will be faster.

This is going to matter for unix timestamps :)

As an impartial anonymous internet user, I must admit that the following ruby snippet is much nicer:

200.times { |a| 200.times { |b|
d = a*a-b*b*b
puts a*a-d/2 if d.abs == 2
} }

> 26

Doesn't prove anything as float is an approximation.

And you should work with unix timestamps !

The following Python script will demonstrate that 26 is the only age within human lifespan boundaries that verifies both conditions.

----------------------
from math import *

for age in range(1,150):
if ((modf((age-1)**(1.0/2))[0] == 0.0) and (modf((age+1)**(1.0/3))[0] == 0.0)):
print "Age %d is ok" % age
----------------------

But it does not impress girls as much as you do ;)

Thank you Julien, I hadn't fully appreciated how exciting an age 26 really is -- and I have never gotten a proof as a birthday gift before!
