Mordecai-Mark Mac Low

In college, Mordecai-Mark Mac Low decided to take science classes that looked like fun. So he chose astrophysics, which uses physics to under- stand how the universe works. Today, he's an astrophysicist, studying how stars, planets, and galaxies form. Since these process take millions of years, he models them using computer simula- tions. Then he compares the models to observa-tions of objects at different stages of formation.
