Rosie wrote an article last week for Jump! Mag, telling us about her life on a farm. What you did not know when you read that piece, is that Rosie has special needs. Her mother explains how it is to live with a child with special needs.
I believe that you know immediately after giving birth that your child is different somehow.
As they grow, you notice that some milestones are different from the ones that your other children had and you silently chide yourself for comparing them.
Slower with walking, not speaking, unusual behaviour, unusual reactions to noise or red food.
You live with it every day and it becomes normal behaviour to you and your family, you adapt to the child’s needs and try to help them make sense of all that their jumbled up senses bring them.
Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.
Cold, rough concrete beneath my burnt yellow hands, ash under my nails. I hold the butt of an already smoked cigarette in my mouth, looking hopeless. Not even the phrase, “Any spare change?” will get anybody to notice me, the old tramp of Brixton, sitting on the side of a busy main road. Every day I get unhelpful comments from young school kids, such as, “The local druggie! Ha, ha, ha…” These don’t make me feel better. It’s not my fault I’m unemployed, homeless and either drunk or high most of the time. Or is it?
People ask me how on earth I find all the money to buy over fifty cans of beer a week and a rather large variety of harmful grasses from drug-dealers. Sometimes I wonder too. I’ve only ever stolen something once. Twice then. OK! I’ve stolen eight times! Where else am I supposed to get money from (not including vulnerable children’s purses)? But, I’ve been thinking… Maybe, just maybe, it would be a slight possibility – just a slight one – that I could consider starting afresh. By ‘afresh’ I mean a new life in which I give up all my addictions, that are slowly rotting my bones, and make lasting friendships, that won’t break. Ever.
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.
