The modern world is an electrified world with things like computers and televisions and so on.But they are nothing compared to the the light bulb,which has greatly changed human existence by illuminating the night and making it easier for us to do a wide range of activities. The electric light,that mostly affects our lives, was invented in 1879 by Thomas Alva Edison.
The scientific concept behind the light bulb is to use electricity to heat a thin strip of filament until it gets hot enough to glow.An electric current will pass through the filament,heating it, to produce light.The enclosed light bulb will also help to prevent oxidation of the hot filament.
I feel that the invention of light bulb is fascinating because it helps us in a lot of different ways and I am sure that without it,our life will be very different.

Without light, we'll be living in a house with no lights, no computers, no air-con, no fan abd etc. If I were to live like that, i'd rather die!
