– [Announcer] This is Sissel Tolaas. She is many things. An artist, a scientist, but more importantly, a smell expert. She, however, prefers another title. – [Announcer] Which means what, exactly? – [Announcer] Right, the point is, she’s dedicated her life
to the sense of smell, what it means, and how it can be used to understand the world and each other. – [Announcer] So how
exactly did she go about recording and then reproducing these smells? – [Announcer] Name a city,
a neighborhood within a neighborhood, a
historical building, or even an era in time, and most
likely Sissel has reproduced that smell, along with
thousands of other scents here in her lab, with the
hopes of using the findings for a bigger purpose.
