All snow flakes are not different

snow flakes travel from the cloud to the ground is full of bends, turns and pyörähtelyjä, and each of them gives putoajalle a little more about your own form.

when Falling ice crystals grow and can begin to resemble not only the stars but also as, for example, a bullet. Along the way the crystals combines the bigger snow hiutaleeksi, but crystal can be a flake just by themselves.

the Ground you end up the go hiutaleella your eyesight is already so much that two ground elegant look never the same.

So they say. Is it true? And if so, can you prove it without checking the earth every one of the snowfall every single ground elegant?

the California university of technology (switch to another service) physicist Kenneth Libbrecht grabbed the challenge and showed in the end that snow hiutaleille can also create twins.

Fotomikroskooppikaan can't see the difference between

Libbrecht grows by ice crystals in the sapphire glass surface of the laboratory cooler for two decades, until it was ready to declare kaksostutkimuksen results.

One of the crystal growth went from 15 minutes to an hour. The result form depends on the kind of your Libbrecht adjust the temperature and humidity. The shape of the spectrum was huge, she told optical microscopy believes in the doctrine of the inspection activity results.

in the lab, either created ice crystals a couple of you are not similar to the last molecule of water to the brim, he admits, but the appearance is like identical twins. The difference does not appear, although the optical microscope resolution is exceedingly accurate, millimeter-thousandth of a class.

Identical crystals in the creation not come to break the laws of physics, they just found a loophole, Libbrecht describes investigations into the website (you navigate to another service).

snowflakes are the researcher also art

Libbrecht says it is likely that also in nature is the appearance of identical snow flakes. However, they can only be monocrystalline, and the water molecules must be exceptionally low.

He illustrates (you move to another service) forms of emergence by comparing the water molecules to organise opportunities for the bookcase books. Although they were only 15, they can set on the shelf more than trillion ways. Trillion is a number one after 12 zero.

Already smaller there's ice crystals from water molecules typically 10 to 18, so the combination possibilities are really staggering. What more crystal snowflake is, the higher your very own appearance a possibility.

Thus, each snowflake can be declared to be unique, so this winter than the earth's entire snow rainy history, Libbrecht amount.

He has done the research sector also the photographic art. Even his website (you navigate to another service) presents.
