fish drink a lot of water to overcome loss
of water from their bodies by osmosis (water
naturally pases from where it is at high concentration
in the fish across its membranes into the
salary water where it is at lower concentration).
At the same time, marine fish excrete salt
from their gills and in a small amount of
& accurate way to know the speed of any
of wood is thrown overboard at the bow, and
the time is taken with a stop watch. When
it reaches the stern the time is taken again.
Suppose the length of the boat is feet and
the time taken is seconds, then the speed
of the boat in konts = 6
The calculation is a very simple one, and
although the method may seem crude it works
very well in practice, even in small boats.
positive side of life:
on earth is expensive, but it includes a free
trip around the sun every year.
How long a minute is depends on what side
of the bathroom door you'r on.
Birthdays are good for you, the more you hav
the longer you live.
Happiness comes through doors you did not
even know you left open.
Even notice that the people who are late are
often much jollier than the people who have
to wait for them?
