# Why are no two snowflakes the same?

• full-time-climb
In summary, the conversation discusses the concept of whether or not two snowflakes can be identical. Some argue that it is a matter of probability and that there have been too many snowflakes for there to be duplicates. Others argue that nothing in the universe is truly identical and that everything is a unique creation. The conversation also touches on the idea of a creator and how energy can be seen as the creator.

This question may not be as simple as it first appears. Or it may be. Thoughts? Hints to follow if required.

How can you be sure there are no two snowflakes the same?

beautiful question though. One of those true, basic, sensing, when you're a child, questions.

Because you define 'the same' in some convenient fashion like, two entities are 'the same' if and only if they are the same entity (maybe at different times).

The question is, after all, really:
"Why are no two [distinct] snowflakes the same?"

Snowflakes can be very similar to each other, so similar, in fact, that calling them alike would be fair. They can certainly be similar enough that you would not be able to distinguish two photographs of one of them from one photograph of each.

.. and sadly presumptious rationalism can destroy all the fun

Cause what we cannot talk about we must pass over in silence..

OK, how about congruent for all of you who don't like "the same".

I don't think you can say with metaphorical certitude that no two are congruent. I think it is a matter of probability. Each time a water molecule is added, it has different ways to fit in. It would be like flipping a coin some very large number of times, and getting the exact same sequence. Make the number of flips high enough, and the odds become very low - perhaps so low that a very large number of trials has a negligible chance of producing two duplicate sequences.

How many molecules in a snowflake? How many ways are there for a molecule to be added to the structure? How does symmetry effect the probability? How many snowflakes have there been?

I have lost two friends over conversations on this idea and an argument that followed and went something like this. But MY thoughts are that if you have parallel universes where almost everything but a speck is identical, you cannot call two John's the same even if they are the same in every aspect in universes the same in every aspect except for the little speck of difference somewhere far far away from the Johns and won't bother them during their lives. Because I want to be right when I say "John lives in a universe where a certain speck far far away from John is attacking people at a very specific location." If this can't be true, then damn John and his alter ego and his ARGGH damn John. Hey, your name is John! Then if you have Johns that are different, you are going to decide on whether or not to call them the same for practical reasons. Hug John because he's wearing a fez? You'll have to examine the Johns for fezzes, if one has a fez and the other doesn't, you're going to have to call them two different things when considering hugging. Snowflakes ARE the same? I think I'm missing something.

Great replies, I love this site!
Snow flakes are a great example of the creator creating. Every single thing you see is a "one of". Each is its own creation. For two things to be the same they would have to be the same thing. Any two things contain their own "matter". The world is full of similarities but no two items are the same.
The snow flake is a great example of this.

what creator?

the one who creates...

is there such a thing as creation?

Creator...Good question. Was going to take the day to reply but then it hit me...

The "E" in E=MC^2

John

that would be energy (IMO)

NO opinion required...it is energy...

So E being the creator, means that everything is the creator...basically removing the concept of creator from that use of the word...

okay you take a gallon of snow and after you analyze/make a diagram every individual snowflake then ask why none are the same

When I think about asking if two snowflakes can be the same I usually try to guess the chances of the person I'm talking to killing me. Hypothermia wonderland is not the best time to ask such questions as Why are no two snowflakes the same?

E being the creator don't make since. Since everything comes from E then there was no creation. Merely just converting and making the converter everything. So E is the converter. Makes perfect sense. Since we weren't created just converted like the houses we live in converted from trees. Our bodies converted by the food we eat. blah blah blah eh.

Here's a big number...The amount of "E" required to produce the mass of the universe.
Dang

Depends on the scales you use. Before the universe (leaving out the fact that we probably can't apply logic to this period), there are no defined reference frames, so in comparison to an boundless sea of possibility and impossibility, I would think it pretty infinitessimal.

## 1. What causes snowflakes to have unique shapes and patterns?

Each snowflake has its own unique shape and pattern because of the way it is formed. When water vapor freezes into a snowflake, it is influenced by many different factors such as temperature, humidity, and air currents. These factors affect the growth of the snowflake, resulting in a one-of-a-kind shape and pattern.

## 2. Are there any identical snowflakes?

It is highly unlikely that two snowflakes will have the exact same shape and pattern. This is because the conditions in which they are formed are constantly changing, leading to variations in the growth of each snowflake. However, there have been a few rare cases where identical snowflakes have been found, but they were formed in controlled laboratory conditions.

## 3. How do scientists study the shapes and patterns of snowflakes?

Scientists use a technique called crystallography to study the shapes and patterns of snowflakes. They use specialized microscopes to examine the intricate details of snowflakes and take photographs to document their unique structures. This allows them to better understand the processes involved in the formation of snowflakes.

## 4. Can snowflakes change shape as they fall from the sky?

Yes, snowflakes can change shape as they fall from the sky. This is because they are constantly exposed to changing environmental conditions, such as temperature and humidity. As a result, their size and shape can evolve as they travel through different layers of the atmosphere before reaching the ground.

## 5. Are there any other factors that can affect the shape and pattern of snowflakes?

In addition to temperature, humidity, and air currents, there are other factors that can influence the shape and pattern of snowflakes. These include the presence of impurities in the water vapor, the speed at which the snowflake falls, and the angle at which it falls. All of these factors contribute to the uniqueness of each snowflake.
