thought of the day.

actually someone asked me this before.. but to ask this again..

If a tree falls down in a forest with no-one around does it makes a sound?

hey.. dun say 'of course!!' immediately.. think abt it.. wat is sound to u? if ur ans is 'waves in de air tat will then vibrate the air in ur ears'.. so this means tat a sound is a sound if u hear it.. so if no one's there, will there then be a sound? hah. puzzled? think abt it bah..
