- Serendipity
Serendipity is the effect by which one accidentally discovers something fortunate, especially while looking for something else entirely. The word has been voted as one of the ten English words that were hardest to translate in June 2004 by a British translation company.Fact|date=May 2008 However, due to its sociological use, the word has been imported into many other languages (Portuguese "serendipicidade" or "serendipidade"; French "sérendipicité" or "sérendipité" but also "heureux hasard", "fortunate chance"; Italian "serendipità"; Dutch "serendipiteit"; German "Serendipität"; Swedish, Danish and Norwegian "serendipitet"; Romanian "serendipitate"; Spanish "serendipia" ).
Etymology
The word derives from "Serendip", the old Persian name for
Sri Lanka , ["OED ", "serendipity".] and was coined byHorace Walpole on28 January 1754 in a letter he wrote to his friend Horace Mann (not the same man as the famed American educator), an Englishman then living in Florence. The letter read,:"It was once when I 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: for instance, one of them discovered that a camel blind of the right eye had travelled the same road lately, because the grass was eaten only on the left side, where it was worse than on the right—now do you understand "serendipity"? One of the most remarkable instances of this "accidental sagacity" (for you must observe that "no" discovery of a thing you "are" looking for, comes under this description) was of my Lord Shaftsbury, who happening to dine at Lord Chancellor Clarendon's, found out the marriage of the Duke of York and Mrs. Hyde, by the respect with which her mother treated her at table." [As given by W. S. Lewis, ed., "Horace Walpole's Correspondence", Yale edition, in the book by Theodore G. Remer, ed.: "Serendipity and the Three Princes, from the Peregrinaggio of 1557, Edited, with an Introduction and Notes, by Theodore G. Remer, Preface by W.S. Lewis". University of Oklahoma Press, 1965. LCC 65-10112]The role of serendipity in science and technology
One aspect of Walpole's original definition of serendipity that is often missed in modern discussions of the word is the "sagacity" of being able to link together apparently innocuous facts to come to a valuable conclusion. Thus, while some scientists and inventors are reluctant about reporting accidental discoveries, others openly admit its role; in fact serendipity is a major component of scientific discoveries and inventions. According to M.K. Stoskopf [ [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=16179740&query_hl=2&itool=pubmed_DocSum Observation and cogitation: how serendipity provid... [ILAR J. 2005 - PubMed Result ] ] "it should be recognized that serendipitous discoveries are of significant value in the advancement of science and often present the foundation for important intellectual leaps of understanding".
The amount of contribution of serendipitous discoveries varies extensively among the several scientific disciplines.
Pharmacology andchemistry are probably the fields where serendipity is more common.Most authors who have studied scientific serendipity both in a historical, as well as in an
epistemological point of view, agree that a prepared and open mind is required on the part of the scientist or inventor to detect the importance of information revealed accidentally. This is the reason why most of the related accidental discoveries occur in the field of specialization of the scientist. About this,Albert Hofmann , the Swiss chemist who discoveredLSD properties by unintentionally ingesting it at his lab, wrote:"It is true that my discovery of LSD was a chance discovery, but it was the outcome of planned experiments and these experiments took place in the framework of systematic pharmaceutical, chemical research. It could better be described as serendipity."
The French scientist
Louis Pasteur also famously said: "In the fields of observation chance favors only the prepared mind." [Original French, as at : "Dans les champs de l'observation le hasard ne favorise que les esprits préparés."] This is often rendered as "Chance favors the prepared mind."History, of course, does not record accidental exposures of information which could have resulted in a new discovery, and we are justified in suspecting that they are many. There are several examples of this, however, and prejudice of preformed concepts are probably the largest obstacle. See for example [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=16608738&query_hl=4&itool=pubmed_docsum] for a case where this happened (the rejection of an accidental discovery in the field of self-stimulation of the brain in humans).
Examples of serendipity in science and technology
Chemistry
*
Gelignite byAlfred Nobel , when he accidentally mixed collodium (gun cotton ) withnitroglycerin
*Polymethylene byHans von Pechmann , who prepared it by accident in 1898 while heatingdiazomethane
*Low density polyethylene by Eric Fawcett and Reginald Gibson at the ICI works in Northwich, England. It was the first industrially practical polyethylene synthesis and was discovered (again by accident) in 1933
*Silly Putty by James Wright, on the way to solving another problem: finding arubber substitute for theUnited States duringWorld War II .
*Chemical synthesis ofurea , byFriedrich Woehler . He was attempting to produceammonium cyanate by mixingpotassium cyanate andammonium chloride and got urea, the firstorganic chemical to be synthesised, often called the 'Last Nail' of the coffin of theÉlan vital Theory
*Pittacal , the first syntheticdyestuff , byCarl Ludwig Reichenbach . The dark blue dye appeared on wooden posts painted withcreosote to drive away dogs who urinated on them.
*Mauve , the firstaniline dye , by William Henry Perkin. At the age of 18, he was attempting to create artificialquinine . An unexpected residue caught his eye, which turned out to be the first aniline dye—specifically, mauveine, sometimes called aniline purple.
*Racemization , byLouis Pasteur . While investigating the properties of sodium ammonium tartrate he was able to separate for the first time the twooptical isomer s of the salt. His luck was twofold: it is the only racemate salt to have this property, and the room temperature that day was slightly below the point of separation.
* Teflon, byRoy J. Plunkett , who was trying to develop a new gas forrefrigeration and got a slick substance instead, which was used first for lubrication of machine parts
* Cyanoacrylate-basedSuperglue (a.k.a. "Krazy Glue") was accidentally twice discovered by Dr.Harry Coover , first when he was developing a clearplastic forgunsight s and later, when he was trying to develop a heat-resistantpolymer for jet canopies.
*Scotchgard moisture repellant used to protectfabrics andleather , was discovered accidentally in 1953 byPatsy Sherman . One of the compounds she was investigating as arubber material that wouldn't deteriorate when in contact withaircraft fuel spilled onto atennis shoe and would not wash out; she then considered the spill as a protectant against spills.
*Cellophane , a thin, transparent sheet made of regenerated cellulose, was developed in 1908 by Swiss chemistJacques Brandenberger , as a material for covering stain-proof tablecloth.
* The chemical elementhelium . British chemistWilliam Ramsay isolated helium while looking forargon but, after separatingnitrogen andoxygen from the gas liberated bysulfuric acid , noticed a bright-yellowspectral line that matched theD3 line observed in thespectrum of theSun .
* The chemical elementIodine was discovered byBernard Courtois in 1811, when he was trying to remove residues with strongacid from the bottom of his saltpeter production plant which usedseaweed ashes as a prime material.
*Polycarbonate s, a kind of clear hardplastic
* The syntheticpolymer celluloid was discovered by British chemist and metallurgistAlexander Parkes in 1856, after observing that a solid residue remained after evaporation of thesolvent from photographic collodion. Celluloid can be described as the first plastic used for making solid objects (the first ones beingbilliard balls, substituting for expensiveivory ).
*Rayon , the first syntheticsilk , was discovered by French chemistHilaire de Chardonnet , an assistant toLouis Pasteur . He spilled a bottle ofcollodion and found later that he could draw thin strands from the evaporated viscous liquid.
* The possibility of synthesizingindigo , a naturaldye extracted from a plant with the same name was discovered by a chemist named Sapper who was heatingcoal tar when he accidentally broke athermometer whose mercury content acted as acatalyst to producephthalic anhydride , which could readily be converted into indigo.
* The dyemonastral blue was discovered in 1928 inScotland , when chemistA.G. Dandridge heated a mixture of chemicals at high temperature in a sealediron container. The iron of the container reacted with the mixture, producing somepigment s calledphthalocyanine s. By substitutingcopper for iron he produced an even better pigment called 'monastral blue', which became the basis for many new coloring materials forpaint s,lacquer s andprinting ink s.
*Acesulfame , anartificial sweetener , was discovered accidentally in 1967 by Karl Claus atHoechst AG .
* Another sweetener,cyclamate , was discovered by US chemistMichael Sveda , when he smoked a cigarette accidentally contaminated with a compound he had recently synthesized.
*Aspartame (NutraSweet) was accidentally ingested byG.D. Searle chemistJames Schlatter , who was trying to develop a test for an anti-ulcer drug.Pharmacology
*
Penicillin byAlexander Fleming . He failed to disinfect cultures ofbacteria when leaving for his vacations, only to find them contaminated with "Penicillium "mold s, which killed the bacteria. However, he had previously done extensive research into antibacterial substances.
* Thepsychedelic effects ofLSD byAlbert Hofmann . A chemist, he intentionally ingested a small amount of it upon investigating its properties, and had the first "acid trip " in history, while cycling to his home in Switzerland; this is commemorated among LSD users annually asBicycle Day .
*5-fluorouracil 's therapeutic action onactinic keratosis , was initially investigated for its anti-cancer actions
*Minoxidil 's action onbaldness , originally it was an oral agent for treatinghypertension . It was observed that bald patients treated with it grewhair too.
*Viagra (sildenafil citrate), an anti-impotence drug. It was initially studied for use inhypertension andangina pectoris . Phase I clinical trials under the direction ofIan Osterloh suggested that the drug had little effect on angina, but that it could induce marked penileerection s.
*Retin-A anti-wrinkle action. It was avitamin A derivative first used for treating acne. The accidental result in some older people was a reduction of wrinkles on the face
* Thelibido -enhancing effect ofl-dopa , a drug used for treatingParkinson's disease . Older patients in a sanatorium had their long-lost interest in sex suddenly revived.
* The firstbenzodiazepine ,chlordiazepoxide (Librium) was discovered accidentally in 1954 by theAustria n scientist DrLeo Sternbach (1908–2005), who found the substance while cleaning up his lab
* The firstanti-psychotic drug,chlorpromazine , was discovered by French pharmacologistHenri Laborit . He wanted to add an anti-histaminic to a pharmacological combination to prevent surgical shock and noticed that patients treated with it were unusually calm before the operation.
* the anti-cancer drugcisplatin was discovered byBarnett Rosenberg . He wanted to explore the inhibiting effects of anelectric field on the growth ofbacteria : it was rather due to anelectrolysis product of theplatinum electrode he was using.
* The anestheticnitrous oxide (laughing gas). Initially well known for inducing altered behavior (hilarity ), its properties were discovered when British chemistHumphry Davy tested the gas on himself and some of his friends, and soon realised that nitrous oxide considerably dulled the sensation ofpain , even if the inhaler were still semi-conscious.
* The anesthetic ether
*Mustine , a derivative ofmustard gas (achemical weapon ), used for the treatment of some forms ofcancer . In 1943, physicians noted that the white cell counts of US soldiers accidentally exposed when a cache of mustard gas shells were bombed inBari ,Italy , were decreased, and mustard gas was investigated as a therapy forHodgkin's lymphoma .
* The first oral contraceptive (a.k.a. "The Pill") was discovered by Dr.Carl Djerassi accidental production of syntheticprogesterone and its intentional modification to allow for oral intake
*Prontosil , anantibiotic of thesulfa group was anazo dye . German chemists atBayer had the wrong idea that selective chemicalstain s of bacteria would show specific antibacterial activity. Prontosil had it, but in fact it was due to another substance metabolised from it in the body,sulfanilimide .Medicine and Biology
*
Bioelectricity , byLuigi Galvani . He was dissecting afrog at a table where he had been conducting experiments withstatic electricity , Galvani's assistant touched an exposedsciatic nerve of the frog with a metalscalpel , which had picked up a charge, provoking amuscle contraction.

* Discovery of the
planet Uranus byWilliam Herschel . Herschel was looking forcomets , and initially identifiedUranus as a comet until he noticed the circularity of itsorbit and its distance and suggested that it was a planet, the first one discovered since antiquity.
*Infrared radiation , again byWilliam Herschel , while investigating thetemperature differences between different colors ofvisible light by dispersingsunlight into aspectrum using a glass prism. He putthermometer s into the different visible colors where he expected a temperature increase, and one as a control to measure the ambient temperature in the dark region beyond the red end of the spectrum. The thermometer beyond the red unexpectedly showed a higher temperature than the others, showing that there was non-visibleradiation beyond the red end of the visible spectrum.
* S. N. Bose discoveredBose-Einstein statistics when a mathematical error surprisingly explained anomalous data.
*High-temperature superconductivity was discovered serendipitously by physicistsJohannes Georg Bednorz andKarl Alexander Müller , ironically when they were searching for a material that would be a perfectelectrical insulator (nonconducting). They won the 1987Nobel Prize in Physics for the discovery.
* Cosmic Microwave Background Radiation, byArno A. Penzias andRobert Woodrow Wilson . What they thought was excessthermal noise in their antenna atBell Labs was due to the CMBR.
*Radioactivity , byHenri Becquerel . While trying to investigate phosphorescent materials using photographic plates, he stumbled uponuranium .
*X rays , byWilhelm Roentgen . Interested in investigatingcathodic ray tube s, he noted that somefluorescent papers in his lab were illuminated at a distance although his apparatus had an opaque cover

*Metallic hydrogen was found accidentally in March 1996 by a group of scientists atLawrence Livermore National Laboratory , after a 60-year search.
* Thethermoelectric effect was discovered accidentally byEstonia n physicistThomas Seebeck , in 1821, who found that avoltage developed between the two ends of ametal bar when it was submitted to a difference oftemperature .
*Pluto 's moon Charon was discovered by US astronomerJames Christy in 1978. He was going to discard what he thought was a defectivephotograph ic plate of Pluto, when hisStar Scan machine broke down. While it was being repaired he had time to study the plate again and discovered others in the archives with the same "defect" (a bulge in the planet's image which was actually a large moon).Inventions
* Discovery of the principle behind
inkjet printer s by a Canon engineer. After putting his hotsoldering iron by accident on his pen, ink was ejected from the pen's point a few moments later.
*Vulcanization ofrubber , byCharles Goodyear . He accidentally left a piece of rubber mixture withsulfur on a hot plate, and produced vulcanized rubber
*Safety glass , by French scientistEdouard Benedictus . In 1903 he accidentally knocked a glass flask to the floor and observed that the broken pieces were held together by a liquidplastic that had evaporated and formed athin film inside the flask.
*Corn flakes andwheat flakes (Wheaties ) were accidentally discovered by theKelloggs brothers in 1898, when they left cookedwheat untended for a day and tried to roll the mass, obtaining a flaky material instead of a sheet.
* Themicrowave oven was invented byPercy Spencer while testing amagnetron forradar sets atRaytheon , he noticed that apeanut candy bar in his pocket had melted when exposed to radar waves.

*Chocolate chip cookies were invented byRuth Wakefield when she attempted to makechocolate drop cookies . She did not have the required chocolate so she broke up acandy bar and placed the chunks into the cookie mix. These chunks later morphed into what is now known aschocolate chips .erendipitous ideas
Some ideas and concepts that came to scientists through accidents or even dreams are also considered a kind of serendipity. Some examples (coincidentally all are regarded with suspicion by science historians):
*
Isaac Newton 's famedapple falling from a tree, led to his musings about the nature ofgravitation .
* The German chemistFriedrich August Kekulé von Stradonitz dream ed aboutOurobouros , asnake running around and forming a circle, leading to his solution of the closed chemical structure ofcyclic compound s, such asbenzene .
*Archimedes ' prototypical cry of Eureka when he realised that his body displacing water in the bathtub allowed him to measure the volume of any irregular body, such as agold crown.Other examples of serendipity
Stories of accidental discovery in
exploration abound, of course, because the aim of exploration is to find new things and places. The principle of serendipity applies here, however, when the explorer had an aim in mind and found another unexpectedly. Some classical cases were discoveries of the Americas by explorers with other aims.The first European to set foot onNorth America wasLeif Ericsson , who was trying to escape from astorm . The Americas were also accidentally re-discovered (seeLeif Ericsson ) byChristopher Columbus , who was actually looking for a new way toIndia .South-America was also discovered by accident, first bySpaniard Vicente Pinzon , who was only exploring theWest Indies previously discovered by him and Columbus, and stumbled upon the Northeast ofBrazil , in the region now known asCabo de Santo Agostinho , in the state ofPernambuco . He also discovered the Amazon andOiapoque rivers; andPedro Álvares Cabral , a Portugueseadmiral , who was sailing with his fleet toIndia via the South African route discovered byVasco da Gama and was deviated to the coast of Brazil.Uses of serendipity
Serendipity is used as a sociological method in
Anselm L. Strauss ' andBarney G. Glaser 'sGrounded Theory , building on ideas by sociologistRobert K. Merton , who in "Social Theory and Social Structure" (1949) referred to the "serendipity pattern" as the fairly common experience of observing an unanticipated, anomalous and strategic datum which becomes the occasion for developing a new theory or for extending an existing theory.Robert K. Merton also coauthored (withElinor Barber ) "The Travels and Adventures of Serendipity " (Princeton: Princeton University Press, 2003), which traces the origins and uses of the word "serendipity" since it was coined. The book is "a study in sociological semantics and the sociology of science", as the subtitle of the book declares. It further develops the idea of serendipity as scientific "method" (as juxtaposed with purposeful discovery by experiment or retrospective prophecy).There is are "Serendipity books" which tell fairy tales that teach children valuable life lessons through the characters mishaps. They are written by Stephen Cosgrove and illustrated by Robin James.The exact meaning of serendipity
There are three interrelated debates regarding the meaning of the word "serendipity":Fact|date=February 2007
* The first debate: are the events referred to by Walpole in his letter to Mann, good examples of "serendipity", as defined by Walpole? Expanding on this debate, are any of the adventures of the Three Princes, good examples of Walpole's definition of serendipity?
* The second debate: if the examples of serendipity cited by Walpole are not good examples of serendipity, what should determine the meaning of the word "serendipity", Walpole's precise definition, or a definition derived from the adventures of the Three Princes?
* The third debate: given the range of current definitions for the word "serendipity", from Walpole's precise or strict definition to extremely loose definitions, what events should be cited as actual occurrences of serendipity?Quotations on serendipity
* "In the field of observation, chance favours only the prepared mind."

William Boyd coined the term zemblanity to mean somewhat the opposite of serendipity: "making unhappy, unlucky and expected discoveries occurring by design". [Boyd, William. "Armadillo", Chapter 12, Knopf, New York, 1998. ISBN 0-375-40223-3] It derives from
Novaya Zemlya (or Nova Zembla), a cold, barren land with many features opposite to the lush Sri Lanka (Serendip). On this islandWillem Barents and his crew were stranded while searching for a new route to the east.Bahramdipity is derived directly from Bahram Gur as characterized in the "Three Princes of Serendip". It describes the "suppression" of serendipitous discoveries or research results by powerful individuals. [(a) [http://www.the-scientist.com/yr1999/feb/opin_990201.html Sommer, Toby J.
