This stamp has a graphic of a sine wave alternating from north to south polarity, and the text reads: "If you don't know what this means, you shouldn't be buying electronics! This is the 21st century, people... There are no excuses for not knowing the basics of how electricity works!"
Because it drives me NUTS when I ask somebody "What is electricity?" and they say "Uh... it's something that comes out of the wall..." This is the 21st century, and electricity is the driving force of all the information technology we use! I believe there is nothing wrong with being dependent on technology as long as we understand what it is and how it works.
But the general public do not understand how electricity works, so they believe it's some dangerous monster that's just waiting to kill them... No. Electricity is unforgiving of incompetence, but it isn't dangerous. The only danger is in the stupidity of the person working with electricity.
Electromagnetism is in fact the driving force of life itself, and the universe. Life itself is electricity; electrical signals carrying orders from our brains to our bodies, instructing our heart to beat once again and our lungs to fill with air; carrying our thoughts as electric impulses from neuron to neuron. And the universe? Gravity is driven by electromagnetism.
So we must make every effort to understand what electricity is and how it works, instead of saying "Um... it's something that comes out of the wall."
