National Static Electricity Day was created in honor of the amazing phenomenon that accompanies us throughout our lives! Sometimes it is really annoying – some things “stick” to the body, creating an unnecessary effect. It is noteworthy that the Greek philosopher Thales of Miletus first announced it, but researchers were able to unravel it much later.
Centuries ago, people noticed that some materials are attracted after friction. Scientists have identified more and more objects capable of exhibiting such power. Some have even suggested that there were some fluids between things to explain this behavior. Charles Dufay identified several types of changes – repulsion and attraction, and replaced “fluid” with the word “charge”.
In 1780, the French military engineer and physicist Charles Coulomb made accurate measurements of the charge. The work was not in vain – later a unit of measurement was created, named after the experimenter. We use it now – a pendant. Throughout history there have been many figures involved in research, it is impossible to mention each of them. Worth reading about them on National Day!
Did you know that static electricity is used to:
- pollution control using a special device that has a board with a static component that sprays particles into the air;
- the production of air fresheners – the molecules inside the can cut out smoke and dust, creating an accumulation of charges;
- the science of xerography, being used in photocopiers;
- vehicle painting.
How to celebrate
On National Static Electricity Day, watch documentaries that explain complex things in simple terms. Find scientific literature and read it. Meet a familiar physicist and talk about the phenomenon. Do your own experiments!
