If an object's shape is described as reniform, what shape is it?
Shape theory of olfaction the vibration theory of smell." While Turin comments that Block used "cells in a dish rather than within whole organisms" and that "expressing an olfactory receptor in human embryonic kidney cells doesn't adequately reconstitute the complex nature of olfaction..." Vosshall responds "Embryonic kidney cells are not identical to the cells in the nose ... but if you are looking at receptors, it's the best system in the world." Shape theory of olfaction The Shape theory of smell proposes that a molecule's smell character is due to its molecular shape, molecular size and functional groups. It has also been described by
Shape used in the vulgar sense, and means what one would normally expect it to mean. [...] We here define ‘shape’ informally as ‘all the geometrical information that remains when location, scale and rotational effects are filtered out from an object.’ Shapes of physical objects are equal if the subsets of space these objects occupy satisfy the definition above. In particular, the shape does not depend on the size and placement in space of the object. For instance, a "" and a "p" have the same shape, as they can be perfectly superimposed if the "" is translated to the right
