Title: Lessons Learned from Time-resolved Spectroscopy of Gamma-Ray Bursts

For 50 years, gamma-ray bursts (GRBs) have eluded answering some very important questions: What powers them? What is the emission mechanism? and What is the composition of their jets? I believe that there are clues to finding the answers to these questions in GRB time-resolved spectroscopy. I will outline what we know from spectroscopic studies, what we can infer and conclude with some well-informed guesses.
