Serendipities
Serendipity: to make discoveries, by accident and sagacity, of things not in quest of.
The word serendipity was coined by Horace Walpole (1794) , in a letter he wrote to his friend, Horace Mann, the English resident in Florence.
"I once read a silly fairy tale, called "The Three Princes of Serendip" : as their highnesses travelled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of...".
Examples of Serendipity
Penicillin by Alexander Fleming
* The Accident: Fleming was cleaning up his laboratory when he noticed that the Penicillium mold had contaminated one of his old experiments.
* Sagacity: He had been researching the antibacterial properties of common substances for several years and thus had the experience to realize what he saw.
The serendipitousdiscovery of penicillin is usually attributed to Scottish scientist Alexander Fleming in 1928, though others had earlier noted the antibacterial effects of Penicillium. Fleming noticed a halo of inhibition of bacterial growth around a contaminant blue-green mould on a Staphylococcus plate culture. Fleming concluded that the mould was releasing a substance that was inhibiting bacterial growth and lysing the bacteria. He grew a pure culture of the mould and discovered that it was a Penicillium mould, now known to be Penicillium chrysogenum. Fleming coined the term "penicillin" to describe the filtrate of a broth culture of the Penicillium mould.
