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”.

Shooting stars, Weather, and Rocks falling from the Sky!

 

 

What do shooting stars, weather and rocks falling from the sky have in common? Are you wondering whether we have gone mad asking such a question? Do rocks ever fall from the sky? Of course they do! You might know them better as “meteorites”, and they are meteors, or rocks from outer space, that fall down to the earth. And what does that have to do with weather? It’s not like they come down like rain! And before you say to yourself “meteor shower”, remember that a meteor is actually a shooting star, a space-rock that burns up in the Earth’s atmosphere. Related, yes, but weather, no.

The weather connection is through another word, generally used to mean “study of the weather”. That word is “meteorology”. As you can see, all three have something in common – the word “meteor”.

So what is this word, and how did it come to mean these different things?

Meteor came into English through French in the late 15th century. In French it was meteore. Very similar, you might think. Does this mean that it is a French word. Not at all. The next question we must ask ourselves is where did French get it from? The answer is from Medieval Latin meteorum, which meant “things in the heavens”. But this is not the end of the tale. Latin took the word from ancient Greek, and in Greek we can analyse the word to see what it really means.

The Greek word μετέωρα (meteora) can be broken into two parts: meta, which means “over, beyond” and aora, which comes from the verb αείρω/ αίρω (aeiro, airo), which meant “to raise, lift up”. Even today, in Modern Greek, αιωρείται (aioreitai) means “it hovers”. All this means that the original meaning of the word was “thing that is raised in the air”. And even in ancient times this developed to mean “things in the sky” and gradually came to have the meaning it does today.

Another interesting point is that the word “air” is in fact from the same root as αείρω (aeiro), which makes it a distant cousin, or cognate, of “meteor”.

 

Did you know:

One of the largest and most famous meteor craters is to be found in northern Arizona, desert of the U.S. It is 1,200m wide, 170m deep and calculated to be created 50,000 years ago! It is more commonly known as the Barringer Crater.
