During each experiment, study participants were asked to smell the contents of three vials that the scientists had mixed themselves using 128 different odor molecules. Then, using the statistics obtained during the tests, the researchers were able to determine that people can distinguish two odors when their components differ by more than half. In other words, if less than 50 percent of the molecules that make up two odors are identical, your nose will be able to tell. The number one trillion therefore embodies the number of odors you can create by mixing 10, 20 and 30 molecules belonging to a source batch of 128.
