20 Years after Nobel Prize Award for Smell

1. Abstract
Smell is an important human sense and one that is the least understood. In some animals, it is the most important sense that determines survival on Earth. The first theory of smell was developed in the first century B.C. Roman philosopher Titus Lucretius Carus believed that differences in the shapes of “atoms” acting on the organ of smell, stimulate the organ.
