The Power of Probability

An article published at Live Science defends the idea that it is possible that two snowflakes are alike. At least if you believe in probability.

The article says that it is possible to have two snowflakes alike, but with very low probability. Moreover, it totally depends on the way similarity is defined ( number of crystals and shape, for example).

So, be aware when you use the setence "no two snowflakes are alike".

For those who like macro photography, the pictures are very nice.
