How do chemistry, biology and psychology come together to create what people perceive as an aroma? Psychologist, smell scientist and entrepreneur Avery Gilbert talks about what your nose knows and how that science is used every day to create a scent for your world.

Plus, Jim Drobnick, co-curator of the "Odor Limits" exhibition at The Science Center in Philadelphia, Pa., takes a look at how artists have made use of smell in fiction, poetry, art and music — and how scent is being incorporated into artistic works and museum exhibits.
