Begin by thinking of 100 as equivalent  to 1 meter, and increasing sizes
by factor of 10s ,or 101 (10 meters), 102 (10×10 = 100 meters,  103
(10x10x10 = 1.000 meters), 104 (10x10x10x10 = 10.000 meters), so on, until the
limit of our imagination in direction to the macro-cosmos.

Later let’s return, a little faster, up to the point where we started and
continue our trip in the opposite direction reducing distances of travel by
factors of 10 into the micro-cosmos.

Observe the constancy of the laws of the universe and reflect about how much
we still need to learn about things large and things small.
