"Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology and validation."

Famous quotes containing the word chemistry:
“Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes.

I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,not an empty chamber, in which chemistry was left to work alone, but an inhabited house,and for a few moments I enjoyed fellowship with them.”
—Henry David Thoreau (18171862)
