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.
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
This 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?
Luigi 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.

Long before the advent of Christianity, people held celebrations at this time of year. In Germany, they once looked forward to sending Hel, the goddess of the underworld, back down to her abode so they could herald the coming of the spring. In Greece, it was a time to worship the god Dionysus.With the arrival of Christianity, the celebrations continued, but changed in nature, gradually becoming more and more linked to the new religion. The Carnival is held in the period before the start of Lent, and Lent is the time when good Christians were supposed to fast, to abstain from meat
In the UK, we don’t celebrate Carnival, but we do prepare for Lent – that is what Pancake Day is all about, after all. Traditionally, pancakes were made to use up the eggs, fat, and butter, that were not to be eaten during Lent!
Take a trip around the world with us, to find out how other countries celebrate Carnival!
