Hi folks,

For those of us who need to calculate stuff, any stuff:
http://www.wolframalpha.com/screencast/introducingwolframalpha.html

Some examples, relevant to photography (who can find more interesting photo related stuff):

Color:
http://www.wolframalpha.com/input/?i=color

The basic lens formula:
http://www.wolframalpha.com/input/?i=lens+formula

What's the formula for the magnification factor:
http://www.wolframalpha.com/input/?i=magnification

Diffraction of a circular aperture:
http://www.wolframalpha.com/input/?i=diffraction+circular+aperture

The refractive index of glass:
http://www.wolframalpha.com/input/?i=refractive+index+of+glass

The angle of view:
http://www.wolframalpha.com/input/?i=angle+of+view

How large is that A4 paper:
http://www.wolframalpha.com/input/?i=A4+paper

The popularity of our "unguru" Asher's name:
http://www.wolframalpha.com/input/?i=asher

Some background on the homepage of OPF:
http://www.wolframalpha.com/input/?i=www.openphotographyforums.com

The info isn't complete (a bit USA oriented, but things are improving), but it's a nice start.
Try getting some background about your birthdate ...

And although Stephen Wolfram is a serious mathematician, there is also some humor, e.g. when you
ask for "the answer to life, the universe, and everything". The answer is predictably 'correct':

Have fun.

Hi Nicolas,

Yes, but not only Doug.

Here's, amongst others, the weather in Bordeaux (of course you can just look out of the window):

And you can even ask for a forecast for tomorrow by adding the date to the question (nice for planning a shoot).
