THE  MIRACLE IN THE ATOM
                 The ozone is in the upper atmosphere, because there it serves a highly
             vital function for life. It forms a layer approximately 20 km above the at-
             mosphere surrounding the earth like a belt. It absorbs the ultraviolet rays
             emitted by the sun, preventing them from reaching the earth at full intensity.
             Since ultraviolet rays have very high energy, their direct contact with the
             earth would cause everything on the earth to burn up, never allowing life to
             form. For this reason, the ozone layer serves as a protective shield in the at-
             mosphere.
                 In order for life to exist on the earth, all living beings must be able to
             breathe and be protected from harmful sunrays. The one who forms this sys-
             tem is Allah, Who rules over each atom, each molecule. Without Allah's per-
             mission, no power whatsoever could bring these atoms together in different
             proportions as oxygen and ozone gas molecules.


                 Molecules We Taste and Smell
                 The senses of taste and smell are perceptions making man's world more
             beautiful. The pleasure derived from these senses has been a matter of inte-
             rest since ancient times and it has been discovered only recently that these
             are caused by molecular interactions.
                 "Taste" and "smell" are only perceptions that are created by different
             molecules in our sense organs. For instance, the smells of food, drinks, or va-
             rious fruits and flowers we see around us all consist of volatile molecules. So,
             how does this happen?

                 Volatile molecules like aroma of vanilla and aroma of rose reach the re-
             ceptors located on the vibrating hairs in the nasal region called the epitheli-
             um and interact with those receptors. This interaction is perceived as smell in
             our brains. So far, seven different types of receptors have been identified in
             our nasal cavity, which is lined by a smelling membrane of 2-3 cm . Each one
                                                                         2
             of these receptors corresponds to a primary odor. In the same way, there are
             four different types of chemical receptors in the front part of our tongue.
             These correspond to salty, sweet, sour and bitter tastes. Our brains perceive
             molecules arriving at the receptors of our sense organs as chemical signals.
                 It has been discovered how taste and smell are perceived and how they
