Who Invented the First Electric Battery?

When we talk about electric batteries, we often talk about voltage. But did you know that this word is named after the person who invented the first electric battery? First, let’s take a look at what a volt is, and then we’ll find out more about the guy who gave the ‘volt’ its name.

 What is a Volt? 

A volt is defined as a unit of electric potential and electromotive force, and voltage refers to the number of those units. That sounds a lot more complicated than it is! If you think of the water in a tap being like the electricity running through a wire, the voltage means the amount of pressure. This video is quite long but explains it very well. 

 

 

 

Why are Volts Called Volts?

Alessandro Volta

The term actually comes from a name. It was coined in honour of Italian physicist Alessandro Volta, who is recognised as the inventor of the first electric battery. During the 1790s, Volta worked on the theories of electricity of the day.

Volta disagreed with the theory proposed by fellow Italian scientist Galvani that electricity was generated by animal tissue. Instead of experimenting on frogs or other animals, Volta did experiment after experiment with metals.

His persistence paid off, and in 1800, he invented the world’s first battery, known as the ‘voltaic pile’.

 

The Voltaic Pile

Volta's Voltaic Pile, the first electric batteryThis voltaic pile was simple but ingenious. It consisted of a pile of zinc and silver discs. But alternating between them was a piece of cardboard, or a piece of cloth, that had been soaked in saltwater.

There was a wire that connected the zinc disc on the bottom to the silver disc on the top, and this wire was capable of producing sparks.

What else Did Volta Invent?

The invention of the first electric battery brought Volta the most fame and recognition, but he also made other discoveries. He invented the electrophorus, a device that could transfer an electrical charge to other objects, as well as an electrical condensor, and the voltaic cell.

He is also known for having discovered and isolated methane gas. After his death, the volt and voltage were named in his memory.

 What about Galvani?

Yet there is one more twist to the tale. Volta’s longstanding colleague Galvani of the animal electricity theory also left his name in our language. When we say ‘galvanise’ or ‘galvanism’, that is where it comes from.

Despite their differing theories, there was no rivalry between the two scientists. They were both more concerned with the pursuit of knowledge than with whose theory would prove to be right, and it was Volta who first coined the word ‘galvanismo’ in Italian.

The Invention of the Piano

Would it surprise you to know that the piano that was invented 1709 is quite similar to the pianos being sold today? Despite huge leaps in technology over the past couple of centuries, the basic function of the piano haven’t actually changed much. We take a look back in time at the invention of the piano.

Early English – The Latin Alphabet

In our last post, we discovered the runic alphabet and the Futhorc, and now we are going to look at what came next. The Latin alphabet.

The Futhorc was gradually replaced by the Latin alphabet. However, it seems that the Latin alphabet was not perfectly suited to represent English, which contained sounds that did not exist in Latin, and so people adapted it with the addition of a few runes: thorn to represent ‘th’ and wynn to represent ‘w’, as well as a few adaptations in usage of the already existing Latin letters in order to make them better suited to representing English sounds.

Early English Writing – Runes and the Futhorc

runes

Did you know that English hasn’t always been written using the alphabet that we know today? There have been several changes in the way we write over the centuries. We shall start by looking at the runic script. You may already have heard of runes, and perhaps you know that the term refers to some form of writing. We’ll look at runes and the early English alphabet called Futhorc. 

Runic Script

First of all, what are runes? Contrary to what legend and hazy modern stories may tell us, runes are not magical, and they are not an exclusive part of an ancient Celtic religion or only associated with druids. Neither are they symbols of the mysterious or spiritual. It is very simple. Runes are letters.

Runic script is a system of writing that is surprisingly close to what we use today in its concept: runes are the letters in a set of alphabets (sometimes called ‘runic alphabets’). These alphabets were used to write Germanic languages. Not simply German as we know it today, but other languages in the same family. This means that it includes English. In fact, the earliest form of writing for English was runic.

The very early form of English that evolved from a language we call Proto-Germanic, which we believe gave rise to many other languages such as German, Dutch, Swedish and others, is known by the term Old English and sometimes also Anglo-Saxon. The second term reflects the names of the Germanic tribes which are believed to have formed the main group of speakers that arrived on the British Isles to displace Celtic languages. It is this early form of English, Old English, which was written in runes.

 

The Futhorc or Fuþorc

The version of runes used to write Old English is known as the Futhorc. It was developed from the older system of runes used to write other, earlier West Germanic languages, known as the Futhark (fuþark). This Futhark consisted of 24 runes, and the early English speakers found it necessary to expand that and add extra runes to reflect the changes in pronunciation, or the sounds that gradually became part of the language. 

They started by adding two extra runes, and this gradually increased until the Futhorc consisted of as many as 33 runes, or letters. You may be thinking that this is rather a lot – but then consider that our modern alphabet uses combinations of more than one letter in order to represent one sound, such as ‘th’ or ‘sh’ and so on. The Futhorc has a separate letter, the thorn þ, to represent ‘th’. 

Now, in modern English, we use the Latin alphabet with a few modifications to write our language. The Latin alphabet was first adapted from the Etruscan alphabet, which was in turn derived from the Greek alphabet, and this is where we get its name from.

We call it ‘alphabet’ from the first two letters, A and B, which in Greek are alpha and beta: alphabet. So what about this ancient runic system? Where does the name ‘futhorc’ come from?

There is nothing mysterious about it. It is not an arcane word with some sort of symbolic meaning requiring years of study to understand. When we break it down, it is the same idea as the alphabet. The name ‘futhorc’ derives, or comes from, the first six letters of the runic alphabet. These are feoh (F), ur (U), thorn (TH), os (O), rad (R) and cen (C); FUTHORC, as you can see.

 

 

It is essentially the same concept as the alphabet that we use today: each rune, or letter, was used to represent a phoneme, or sound, the basic building blocks of our words.

The Futhorc was used for several centuries to write down English, and for a while when the Latin alphabet was first used for English, the two were both in use at the same time. You can even see some early monuments which have both systems of writing side by side!

Runes were used from around the fifth century to the ninth or tenth centuries in English, although the Germanic Futhark is much older than that.

In our next post, we’ll take a look at the Latin Alphabet, and tell you where you can go to take a look at RL examples of the Futhorc and the Latin Alphabet.

Awesome Women Who Disguised Themselves as Men to Follow their Dreams

Throughout history girls and women have been told, ‘You can’t do that! You are a girl!’ Luckily, this attitude is becoming less common in many countries and cultures, but what did women do in the past? If they wanted to be a doctor, a musician, a sportsperson or even a soldier?

Most women put aside their dreams or practised other activities that were deemed appropriate for women. Some women protested, like the suffragettes who demanded to be allowed to vote. And a small number of women went much further. Today we are taking a look at the women who disguised themselves as men in order to follow their dreams.

 

The first woman to circumnavigate the world – to go all the way around the globe. Born in France, and with an interest in botany (the study of plants), Jeanne became first the housekeeper, and later the partner of a famous botanist Philibert de Commerson.
