Consider the fact that the light bulb and the telephone were invented only three years apart. although it took many more years for such devices to find their way into common household use, they eventually wrought major changes in a relatively brief period of time. what effects did these inventions have on the lives of those who used them? are there contemporary analogies in your lifetime of significant changes due to inventions or technological innovations?

The invention of the light bulb and the telephone and it's used on common household completely change the lifestyles of the people who used them. Imagine that before the invention of the light bulb when the night arouse candles should be litten to illuminate the houses. With the light bulb that change completely and life was improved.

With the telephone being used in common houses it allows people to communicate with others without the necessity of being face to face. That began to make that information travel faster than ever before.

A contemporary analogy in our lifetime is the invention of the smartphone. It completely changes the lifestyle of people around the world. In the palm of your hand, you have more information than ever before and access to talk with almost anyone in the world.

I hope this answer helps you.
