“Necessity is the mother of invention.” I think that this quote means that the simple needs of people like us often leads to ideas about how to make something easier for ourselves and then that leads to an invention. For example, the CD. You can’t exactly just call up Chris Brown and ask him to come over for an hour or so, so that you can have some entertainment. So somebody invented a disc that can play music in your own house. Then people didn’t just want to listen to their music sitting around at home, they wanted to be able to listen on the move. So then the Walkman, a circular contraption that you stuck your CD into and you could listen to anywhere was invented. But then the Walkman became inconvenient, because of its size, ability to only play one CD at a time and not too great sound quality. That really opened up a new era of portable music players, the iPod. This square object, about the size of a note card, could hold up to 10,000 songs at maximum capacity, was small enough to tuck away into the smallest bag, and had quality surround sound of a movie theater. So therefore, I think this quote means that one need evolves into an invention that can make life A LOT easier.
