What is Separation of Powers?

Have you ever heard this term and wondered what is the separation of powers exactly, and why is it so important? If so, then read on because we are going to explain it!

Separation of powers isn’t a new idea – in fact, even the Ancient Greeks had a version of this political system, as did the Romans. There are variations in place across the world.

Each country has a slightly different setup, so we’ll use the United States to explain the concept.

What is the Separation of Powers?

The idea behind it is to have a system in place that prevents one person or group from having all the power over an entire country. If you think back to the days when countries were ruled by a king or queen, who made decisions that affected the lives of everyone who lived in their kingdom – sometimes that went well, but often it didn’t. Instead of one person having all the power, a democracy splits the power between different people or groups of people.

When you think of the person who runs the country, you probably think of the President. The President represents the EXECUTIVE branch of the government.

In the USA, that means that the President executes the instructions of Congress, signs Executive Orders, selects judges to be approved by Congress, and is in charge of the armed forces (the navy, army and airforce).

By the way – don’t get confused by the word ‘execute’, which can mean ‘to put to death, to murder’ but can also mean ‘to carry out, to accomplish’. The President carries out the instructions from Congress, he doesn’t kill them all!

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.

Language & Literature, Written By You

My Multilingual Life – Written By You

‘Do you speak English?’
For British and American girls who travel to a different country, that question is often the first sentence we learn.

 

‘Sprechen Sie Englisch’

‘Parlez-vous Anglais’

‘habla usted Inglés’

‘Вы говорите по-английски’

‘您说英语吗’

 

What is it like for the estimated two thirds of the world’s population who speak at least two languages? The people who we refer to as ‘bilingual’, if they speak two languages, and sometimes as ‘multilingual’, if they speak more than two languages.

The researcher and writer David Crystal estimates that of the approximately 570 million people in the world who speak English, over 41% are bilingual in English and some other language.

Today’s contributor knows all about speaking more than one language.
