As soon as people need something, they invent it. For example, when ancient people felt hunger – they went on hunting and for that they invented the bow and arrows. When they needed to carry heavy cargos to large distances – the wheel was discovered. In fact, every day the humanity faces new challenges that can’t be met using only the existing technologies. And that’s why new inventions are made every day.
Actually, there are people who would challenge even the seemingly obvious statement that “Necessity is the mother of invention”. They say that inventions were not inspired by the necessity alone. Curiosity was, and still is, a powerful stimulus for explorers, researchers, and inventors. Besides, I have heard more than once, sometimes as a joke, the idea that laziness is the mother of invention, as the man by nature has always been trying to make his life easier by all possible means. Laziness combined with ingenuity, inspired the man to boost his strength by means of the lever, the wheel and axle, and the pulley.
For the same reason, the man discovered the sail which enabled him to move fast across the seas without putting any effort into it. But the most obvious proof of this statement is the invention of the remote control for the TV set. Only a very lazy person could have invented a way to avoid having to stand up from a sofa or a recliner to press a button of the TV set manually. Moreover, there is another point of view that jealousy is the mother of invention. It’s known that the man has only invented the wings because people had long envied the birds their ability to fly.
The envy of the fish’s ability to breathe under water has encouraged the man to invent the aqualung. So, those who say that envy gives the start to any progress are not far from the truth. But still, whichever it may be: curiosity, laziness, or jealousy – all of them are nothing but substitutes for necessity. It was necessity that forced the man, almost half-ape, to start using natural objects as tools and later to start making these tools by himself.
