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
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.

Charity Work Experience
A few years ago, our contributor, Laura Montagne was an unemployed English Literature graduate looking for a break into administration or clerical work.
Finding a job was quite difficult, as she was not very confident and didn’t have much practical experience in an office environment.
She was given the opportunity to do work experience for the charity Age Concern, in their office in Christchurch, Dorset.
The job was voluntary; Laura did not get paid but it was a very valuable experience.
Move Over Girls, and Make Space for Ballet for Boys
DANCE is for EVERYONE!
When did people begin to dance? No one knows for sure, but dancing has been around for as long as there have been people!
Dancing provides people with a wonderful tool to express their emotions and thoughts. They can communicate to others what they are feeling and their state of mind. Dancing connect people. All around the world, there is dance. Over many centuries, every country and culture has developed typical dances of its own. They are part of peoples’ traditions.
Aside from these cultural dances, dance developed for performance.
People have always passed on their old dances from generation to generation and always enjoyed dancing them. In addition there were also modifications, changes, new steps and other dance moves. More dances evolved.
We will, in this series of articles, look at the different styles of dance and find out how you can get involved. We shall start with BALLET and ask the question ‘Is ballet for boys too?’
What is ballet?
Ballet was created in the courts of Italian princes about 500 years old. A royal dance school was later founded in France by Louis XIV in 1661.
Many positive benefits are associated with learning the art of ballet. Besides learning the traditional techniques of ballet, ballet lessons can also nurture a positive self image. Ballet teaches skill, grace, poise, self-discipline and confidence. If your dream is to become a dancer, you must practice a lot in order to master the many challenging poses and steps of ballet. You will begin by learning the rules and traditional techniques of ballet.
Why should I learn Ballet?
Ballet lessons have three major benefits. First of all, a dancer expands their vocabulary through learning the French names of the steps and hearing the musical terms. Secondly, they develop their musicality and rhythm through coordinating their bodies to the music. A third benefit is that memorising new steps and dances improves the memory of young ballet students.
So, Ballet makes you smart!
Dance offers a greater range of motion, coordination, endurance and strength than most other physical activities. If you have an interest in any kind of future in dance, you’ll need ballet because that’s where you learn the basics. But even if dance isn’t the ultimate goal, ballet lessons improve posture, flexibility, coordination, strength and grace. They also provide an opportunity for you to be active regardless of the weather outdoors.
So, Ballet makes you fit and strong! This IS looking promising.
Ballet lessons can also be good for a kid’s development by improving their social skills. It’s been suggested that ballet classes encourage kids to form new friendships. Dancers also get to interact with positive role models in their dance teachers. In ballet class, you need to follow directions closely and discipline yourself to not run around the space of the dance studio! Your confidence will grow as you develop new skills and perform in front of an audience. My dancers love to perform for their friends and family. After working hard all year, my students feel a sense of accomplishment while performing on stage in awesome costumes.
So, Ballet can make you a more confident person! What’s not to like?!
Is Ballet just for girls…? No, definitely not! More girls than boys do ballet, but the ballet that girls do is very different from ballet for men and boys. Male ballet dancers have to be strong and athletic. When scientists tested male ballet dancers against sportsmen, they found that the dancers were fitter and able to keep going for longer. Lots of sports clubs invite Ballet teachers in sometimes to give the players a lesson! It’s great for their balance, agility and core strength.
So, Ballet is great for boys too! Sign me up.
