Is Black Really White?
Science will tell you that black is not a colour, rather it is the absence of colour or the fact that there is no colour there. I expect that makes you think of white, rather than black!
And that’s the interesting thing about the word black: it was nearly white. And in fact in several other languages, the same root did develop to mean white.
Being a Teenage Vegetarian
What do you do when you want to become a vegetarian but your parents aren’t too keen? Tabitha explains how her family reacted to her decision, how they have adapted to having a teenage vegetarian in the family and how she eats healthily without meat.
Like a lot of teenagers, I decided to become a vegetarian. Some do so because they want to rebel, some people think it will be healthier, or just don’t like meat that much. I was convinced to go veggie when I was 13 after a biology dissection. It was only a rat, but it made me realise that I didn’t want to be eating animals as I have a pet rabbit and it was just too close to home for me. Also, a Jamie Oliver programme I accidentally watched featuring the making of sausages put me right off… But mainly for me, it was the animals.
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.
Have you ever wondered…about your teeth?
