A World at School – Education for Everyone

We are lucky in the western world. We are entitled to a free education until the age of 18. You might not always feel like going to school, but you are able to learn about loads of different topics, which will help you find a job when you are older. Not only that, but school can be great fun too – we bet you have a favourite subject, that you love to learn about.

A lot of children across the world don’t have this opportunity. Sometimes it is because the children are too poor to be able to afford to go to school, and there is no way they can pay for uniform, travel and schoolbooks. Sometimes it is because the government doesn’t provide free education where they live. Sometimes it is simply because they are girls. You might have seen the story of the girls in Nigeria who have been kidnapped, because they wanted to go to school – we are all hoping very much that they are soon home with their families. Now more than ever, it is vital to ensure children can go to school safely.

Where Does the Word Candidate Come From?

Today is election day in UK, when the citizens of the country choose their new government. You can read all about how the elections work here. You wouldn’t think that dress codes of ancient Rome would affect the elections of today, but they do! Millie Slavidou explains.

Today is a good day to think about the word ‘candidate’. I rather like the etymology of this one.

It comes from Latin candidus, which is the past participle* of candidare, which meant ‘to make white, to make bright’.

Not because of whitewashing whatever the candidates might have said or done! It was because in ancient Rome candidates who wanted to be elected either to the Senate or any other office wore white robes.

If we take it one step further back, to a root meaning ‘white, shining’, we find that ‘candle’ is a cognate.**

 

*Past Particle

The past particle is the past form of the verb that can also be used as an adjective, like “a fallen tree”. In the case above, the adjective is like saying ‘whitened’ in English. Other examples of past particles are:

verb: bite
past particle: bitten
example: a bitten apple

verb: choose
past particle: chosen
example: aa chosen present

verb: crash
past particle: crashed
example: a crashed bicycle

 

**Cognates

A cognate is a distant relative, a word ultimately from the same root. Like a third cousin. Here are some examples of cognates.

 

14126405243_c179f6f9b8_qBook is related to beech. Well, actually, book means beech! Both come from Germanic word meaning beech tree, Buche.

Germanic runes were originally inscribed on tablets made of beech wood. Modern German for book is Buch!

 

2400500463_67988839f0_qWOOL and FLANNEL are distant cognates.  Today, fashion stores often describe plaid shirts as ‘flannel’, but it is actually a soft woven fabric, originally made of wool, but now often cotton or synthetic. You might have a flannel pyjamas, which are lovely and cosy in the winter!
The word wool is from a Proto Indo European root *wele meaning ‘wool’.
 In Welsh, the word gwlanen, means ‘wool’ and is from the same root. The word flannel comes from the woollen vests that were made, presumably by Welsh traders from Welsh sheep –  Gwlanen became fwlanen, and then flannel. So wool and flannel are distant cousins!

You will often find the word ‘candidus’ used in botany or biology to describe something that is white, such as crocus candidus or the white woodpecker Melanerpes Candidus. There is even a white monkey called Propithecus candidus.

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.
