#1 What’s there:The astronaut picking up rocks on the moon,
The nuclear physicist bombarding atoms,
The marine biologist describing a newly discovered species,
The paleontologist digging in promising strata, are all seeking to find out…..

#3 How did it come to be this way? Each of these scientists tries to reconstruct the histories of their objects of study.
Whether these objects are rocks, elementary particles, marine organisms, or fossils, scientists are asking,
