Is time flying too fast or too slow at times?

Do you get the feeling that time isn't fair at times? When you're in a boring meeting or classroom, fifteen minutes seems like an hour and when you're in a conversation with a loved one or surfing the net, one hour feels like fifteen minutes.

Time, believed to be universal, no matter the situation, day or place, time would be same for everyone although it is known that clocks aren't perfect and are subjected to errors.

Albert Einstein coined the term time dilation, that is, different speeds of time at different areas. The was known when two atomic clocks were placed at the top and bottom of a water tower. The clock at the top seemed to run fast whereas the one closer to the centre of the earth (the one at the bottom) moved slower.

Another theory by Paul Langevin, called the twin paradox, stated that if a pair twins, in which one of them lived at the top of a mountain and the other and the foot, they would age differently. The one at the top would age quickly while the one at the foot would age slower.

So, just in case you're doing something you like and want it to last, stay as close to the ground as possible. And during boring meetings, try having it in the room and the highest level.
