Marking time
Start with the familiar- the time between
birthdays. One trip around the sun.
An arm-span is convenient timeline for the
planet. Human presence = one light stroke of
fingernail file.
A 46 meter timeline is manageable and has
enough room for some detail.
•10 meters= 1 billion years
•1 cm = 1 million years
