the world is beautiful to look at, but it's even more beautiful to understand a regular day in the snow. But if you look carefully, there's something deeper. Snowflakes are complex, intricate things. The idea is that the structure of snowflakes can be explained using a few simple laws of nature. And that idea goes to the very heart of science. Because those laws themselves are beautiful and they're universal, they can explain so many things from Snow Flix two stars. How do snowflakes form? Why are they all different and yet tantalisingly similar? These are the questions that can be asked of any naturally occurring structure. Why are beehives regular hexagons? Why do icebergs float? Why a planet spherical? And what's this got to do with free diving grannies? The answer's allow us to glimpse the underlying laws of nature that shaped, Um, this is why when you look at a snowflake, you're peering beyond the everyday world at the deep structure of nature itself, the universe in a snowflake. For all the unpredictability, there is regularity in the behaviour of icebergs. If you look carefully and ask the right questions, which is what science is all about, it's a wonderfully complex and intricate process on. The thing I find most beautiful about it is that when you look at a snowflake, then you can read its entire history. You can see its history made solid. Every individual snowflake has a different history. Every snowflake followed a slightly different path through the clouds and onto the ground, and that means every snowflake grew in a subtly different way. And that's why no two snowflakes are ever alike because no two parts through time are ever alike. When you look at a snowflake, you see history on the deep structure of nature condensed into a frozen moment. It is wonderful, you know that when you think about it, the whole universe, the whole of physics is contained in a snowflake. To describe them, you need all four forces of nature. You need gravity, electromagnetism. You need the nuclear forces, and then you need to understand about symmetry and symmetry. Breaking all the fundamental ideas that underline the laws of physics can be thought off in the journey of a snowflake to the ground. Every snowflake shares the same building blocks, the same basic, beautiful, symmetrical forces of nature at their heart, but because of their histories because of the way they formed there are all different. And so it is with solar systems. So it is with planets. And so it is with people. We're all made of the same building blocks, but we're all slightly and magnificently different because of the history of our formation. The structures we see in the universe like stars and planets and trees and snowflakes are shadows of something deeper. They mask on underlying beauty and simplicity. But isn't it a beautiful thought that our origin and evolution, just like the structure of a snowflake in a snow storm, can be explained by a few simple natural laws? And isn't it a wonderful idea that that thought came from just looking carefully at nature and trying to understand it?
