Winter Wonderings – Are Snowflakes Really All Different?

 

It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.

However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.

The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!

SCIENCE NEWS – Discovery of An Underground Ocean

 

 

Earth’s Underground Ocean

 

In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.

An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.

A Short Story – The White Dove

Dad walks over to me. He’s carrying several slices of bread.

‘Hi, Grace.’

‘Hi,’ I say, giving him a look which I hope he understands means, I am so not impressed with this new pre-birthday arrangement.

Dad doesn’t seem to have noticed my look. I wonder what he’s doing with the bread.

‘For the ducks,’ he says when he catches me staring at it.

I nod and decide not to mention that I am no longer five years old and that feeding the ducks in the park doesn’t exactly excite me anymore.

‘Right,’ I say, as we head over to the pond.

‘So, Grace, how have you been?’

We sit down on the bench next to the willow tree.
