Let there be light

If we start thinking about the most important technologies that the world had seen through the existence of the human kind, the one that is going to be presented in this text is considered a milestone in our history.

The human being has always tried to improve his life, and he has always wanted to make his existence more comfortable. The first question that comes to my mind is: Can you imagine reading or studying at night with just a little flame in the middle of your bedroom? The answer to this question at first glance would be, yes, maybe because it has something cliché.. but not for all the nights of the rest of your lives.

Since Thomas Edison had the awesome idea to invent this particular device, the world started to witness how the light was artificially created. Our lives were changed when the light bulb started to illuminate the most remote places in the world, distant corners that had never been illuminated before, now enjoy this eternal sparkle. 

His invention made our lives hospitable to a wide range of human activities. The benefits that this change produced were innumerable. First, it gave the opportunity to lot of countries (Nordic countries that just receive 6 month of sunlight) to perceive light in the same way we, people from the west, did. Second, with this invention lots of other inventions started to see the light; and of course, it brought lots of bad things too,  that now societies are more aware of it, for example, climate change, light pollution, etc.

Can you imagine how the world would be now, if Thomas Edison had invented another source of the artificial light?
