Rock, Paper, Scissors… Robot???

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.

CURIOUS CREATURES 3 – The Naked Mole Rat

 

The strangest creatures are, to me,

The ones I love the best.

The slimy, ugly and the odd

Are cooler than the rest…

 

When I began this Curious Creatures series for Jump! Mag, I made a list of animals and insects I wanted to cover. I began with the ones I had some sort of connection with and most were animals close to home that I’d seen or heard, which intrigued and inspired me.
But rather impatiently, I’m now going to go a bit further afield and invite you to join me in the strange and extra-extraordinary world of  “Curiouser and Curiouser”*Creature number 3…

The Adventures of Cha-Cha the Dragon – Part 1

A chapter story by Iona…

 

Once upon a time, in ancient China, there lived a wise and mighty dragon. His name was Cha-Cha. He being a magical dragon, he had many enemies. Among these were an ancient race, whom battles with Cha-Cha had all but killed off.

Only one remained. He was the great ”Earth Traveller” or E.T. for short. E.T. could take many forms, including a long pink one that he had to fill in for the birth of his 100th son.Other than these he could take the forms of fearsome animals, such as a tiger, a snake or a badger.

What is Amigurumi?

When 12-year-old Iona wrote to us, offering to write an article for Jump! Mag about Amigurumi, our first question was, “What is Amigurumi?”. She explained and we jumped (ha!) at the chance of having a talented crochet artist bring some colour and cuteness to Jump! Mag.

A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists

kid-friendly explanation of Big Bang

Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.

When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.

Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.

 

 

The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.

The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:

 

“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”

 

Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.
