Tune in for the third episode of Smell of Data: Leanne Wijnsma‘s documentary on the search for a more instinctive Internet. Today we are exploring the sense of smell as a warning mechanism. We will look back at the development of the smell of gas and how we are trained to recognize such odor as a potential hazard. We will also pay a visit to the harbor of Rotterdam, where so-called “e-noses” are employed to detect toxic fumes. Missed the previous episodes? Watch them here.
