Necessity is the mother of invention

"Necessity is the mother of invention" I think this quotes mean that if we need an invention that can improve the daily life of mankind whether it is by speed or the man power needed to power it with a lot of investment and time it will lead to the birth of it. I think an excellent example of that would be the telephone which allows people to contact each other without having to physically going and talking to one another. Another good example would be the airplane which allows people to travel to other countries with out having such a long journey as it would be on a boat. The last example is the lamp which is a replacement for the sunlight which allows people to be able to see into the evening and early morning and into dark corners with out straining their eyes. To summarize I believe this quote means that when the need occurs for an improvement in a utensil that is regular used with the devotion and investment of a person or persons it will lead to its birth.
