Pride of Place – The World of the Lion

Lions are felines, which means that they are members of the same wider family as cats. Indeed, they are frequently referred to as “large cats” or something similar.

They live on plains and savanna in Africa and India, where the sun beats down on the grassland so that it fades, withers and turns yellow – just the colour of a lion, which helps to camouflage it, so that it can blend in with its surroundings and stay hidden.

The Clifton suspension bridge: designed by a woman, built by Brunel

One of the best known landmarks in Bristol, UK, the Clifton suspension bridge first opened in 1864. It was built by the famous British engineer Isambard Kingdom Brunel, but it has recently become public knowledge that it was designed by a woman. Our science editor Sam Gouldson explains who she was and why her work isn’t more widely known.

Who really designed the bridge?

The Clifton suspension bridge was designed by a woman called Sarah Guppy. She was born Sarah Beach in 1770, but when she married her husband Samuel Guppy she took his name. She was one of the great British inventors of her time and the bridge isn’t the only thing she came up with.

What else did she design?

The invention that earned Sarah the most money was her device to prevent barnacles forming on the hulls of ships. Without barnacles the ships would be able to cut better through water and travel more quickly, and the Royal Navy paid her £40,000 for it. That may not sound like much for such a valuable design, but today it would be more than £2.3 million. Her other inventions included a kettle that not only boiled water for tea but could cook an egg and keep toast warm, a candle holder that could keep candles alight for longer and a way of treating boats so that they were more watertight. She also came up with the idea of planting willow and poplar trees on the embankments of new railways, to hold the earth together and prevent landslides.

Why isn’t she more famous?

Sarah lived during the Georgian and Victorian eras. In those times married women weren’t allowed to own property in their own name, and intellectual property such as Sarah’s inventions were no different. Her husband had to file the patents on her behalf, as the property of the Guppy family. The patent for her method of piling bridge foundations in order to create a new kind of bridge was filed in 1811, but she refused to charge others to use the idea because she felt it was for the benefit of the public. Thomas Telford, a civil engineer, used her design to build the Menai bridge in 1826, and when the competition to design the Clifton bridge was announced Sarah gave her work to Brunel. When she wrote to him to suggest the use of willow and poplar trees to reinforce railway embankments, she explained that she didn’t want the credit for her idea because she felt that women “must not be boastful”.

What Does Brexit Mean for Kids?

The British have voted to leave the European Union, but what does this mean, and what does Brexit mean for kids?
Most of you will have heard of the EU Referendum, known as BREXIT (which stands for BRitish Exit). If you don’t know what a referendum is, then this is a good place to find out more.
We asked some of our readers what questions they had about BREXIT. These questions are difficult to answer right now because even the experts don’t know exactly what will happen, but here’s what we know so far. If you have any questions, comment on this post and we’ll try to find the answers for you.

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.
