An Unseen world part 2
Yet remarkable as our eyes 
may be there are many things 
they cannot enable us to see.
Among these are very 
small things. Usually when
we talk about small things
we mean things about the size
period at the end of this sentence. 
Now you can see the end period
quite easily and if it were only 
one-tenth its size you can see the
you could still see it. But if the period 
shranks to one hundredth of its present 
size  you would probably lose sight of it
Yet small as the shrunken period might 
be it would still be much larger than 
millions of different kinds of that exists
in your everyday world.
