My Multilingual Life – Written By You
‘Do you speak English?’
For British and American girls who travel to a different country, that question is often the first sentence we learn.
‘Sprechen Sie Englisch’
‘Parlez-vous Anglais’
‘habla usted Inglés’
‘Вы говорите по-английски’
‘您说英语吗’
What is it like for the estimated two thirds of the world’s population who speak at least two languages? The people who we refer to as ‘bilingual’, if they speak two languages, and sometimes as ‘multilingual’, if they speak more than two languages.
The researcher and writer David Crystal estimates that of the approximately 570 million people in the world who speak English, over 41% are bilingual in English and some other language.
Today’s contributor knows all about speaking more than one language.
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!

What Causes Motion Sickness?
Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.
How to Clean Water
With poor living conditions and water shortages increasing every year across the world, the question of how to clean water efficiently is becoming ever more important.
Does Everyone Have Clean Water?
When you have clean, safe water available at the turn of a tap it’s very easy to take it for granted. But almost 750 million people don’t have access to clean water; that’s one person from every ten in the world’s population. There are many reasons for this, from poverty to poor management by governments.
