Rock, Paper, Scissors… Robot???
The game rock-paper-scissors is well known around the world. We’ve all used it as a choosing method, or simply as a game! The easiest version is played between two people. Both players choose one of the three shapes for one of their hands, and reveal their choice at the same time, hoping their choice beats their opponent.
It’s nearly impossible to gain an advantage over your opponent, unless you wait long enough to identify their choice before you make yours, but the chances are that they will realise your cunning plan and call you a cheater!
This game is not simply a choosing game. There are mathematicians dedicated to constructing algorithms for the best strategy to win, and scientists devoted to creating unbeatable robots! In fact, researchers at the University of Tokyo have created a rock paper scissors robot that wins at rock-paper-scissors 100% of the time.
The Cage of Society
What do you do when you see someone being bullied? And what happens when the bullies are your friends? These were the questions that were occupying the mind of 11 year old Kirsty. Here’s her story.
Not so long ago the only thing on my mind at school was to fit in with my friends and to feel like part of a group.We were a very close circle and I was positive that they were the most loyal, kind and caring friends I could wish for. However, there was one thing that concerned me, their behaviour towards a boy named Ryan.
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.
Why do we get Hiccups?
Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?
What are Hiccups?
Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.
