Fact or Fable? Most body heat is lost through the head
Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.
It’s Fake! – The Truth About Photoshop
I’m sure you have all seen at least one tabloid cover and thought, ‘I wish I looked like that’ or ‘I wish I could be like that’. Caitie is here to tell you that it’s not real.
Awesome Women Who Disguised Themselves as Men to Follow their Dreams
Throughout history girls and women have been told, ‘You can’t do that! You are a girl!’ Luckily, this attitude is becoming less common in many countries and cultures, but what did women do in the past? If they wanted to be a doctor, a musician, a sportsperson or even a soldier?
Most women put aside their dreams or practised other activities that were deemed appropriate for women. Some women protested, like the suffragettes who demanded to be allowed to vote. And a small number of women went much further. Today we are taking a look at the women who disguised themselves as men in order to follow their dreams.
The first woman to circumnavigate the world – to go all the way around the globe. Born in France, and with an interest in botany (the study of plants), Jeanne became first the housekeeper, and later the partner of a famous botanist Philibert de Commerson.
The Contronym – a Word that Bends Over Backwards
I expect most of you have heard of antonyms, and even if you haven’t heard the word, you know them and use them every day. Antonyms are words that mean the opposite. For example, hot is the antonym of cold, rich is the antonym of poor.
But what happens when we have a word that doesn’t have another antonym – it is the antonym of itself?! You are probably wondering what on earth that could mean. Well, there are some words that have two meanings which are the opposite of each other. This makes the word its own antonym. Words like this are known as contronyms.
LEFT
Left and Left Behind
One very common one that we shall start with is a word that you use all the time without ever thinking about it being a contronym. This is left, which can mean “gone, departed” or “still there, remaining” . If you have gone, then you have left, but if everyone else except you has gone, then you are left!
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!
