Abstract
In our daily lives, we see that many things sink in
water, while many others float on it. This raises a
question in our minds: why do some things float
and some others sink? An obvious answer that
comes to our mind is that a stone sinks as it is
heavy and paper or plastic floats as it is light. But
does this answer some other questions? No. A
massive ship does not sink, but a small stone does.
Therefore, we accept there must be some reason
behind these riddles. It is said if there is a reason,
there is essentially science behind it. So, what is
that science?
