The 7 discoveries unintentionally


1.Saccharine
Sakarin Bahan Pemanis Buatan

Saccharine or substance an artificial sweetener found accidentally by a chemist origin russia named constantin fahlberg ( 1850-1910 ) .
One day in 1879 after work all day in his laboratory , he forget to wash hands .
That day he " bullshitting " with material a mixture of charcoal and tobacco in order examines with it .
Arriving dinner at home , she realized that cake rolls he santap as dinner tasteless sweet other than usual .
Asked his wife did he give you sugar to some cake , that the student got not by his wife .
Cakes the rolls tasteless normal as usual for the tongue his wife .
Fahlberg realize that a sweet taste were from his hand and the next morning he went back to his laboratory and started researching to find saccharine .
2. Smartdust
Smartdust

Smartdust was a privacy detection mikroelektrik-mekanis that detects assortment of things like light , temperature , vibration , magnetism and others .
Smartdust found when a phd students university of california named jamie link , destroy a chip silicon being he learned .
Moments later he began to realize that the chip still serves as censorship , although have turned into pieces small .
Sensors of small splinters this is someday called smartdust and very useful as detection instrument thing not can be detected by sensors conventional , as measuring purity sea water and detect pastikel-partikel dangerous that is in the air .
3. Drink kola

Drink kola found when an expert pharmacologists of atlanta named john pemberton misshape to create obat pereda headache .
He mixing all sorts of material by contrivances so what we call the current with kola drink .
At first kola sold only in drug stores use the recipe , and after 8 years drink kola start sold as a beverage free as we know it today .
4. Teflon

A researcher in a chemical company named roy plunkett famous dupont was looking for a material that can be used to replace cfc ( chlorofluorocarbons , an ingredient of cooling commonly used in air conditioners , refrigerators or car commonly called also with freon ) .
He had a theory if he mixing a substance called tfe with hydrochloric acid , he 'il get a substance cooling new desired .
Therefore he gathers gas tfe in considerable quantity that is then he pampatkan and chill in low temperature in a cooper laboratories metal together with hydrochloric acids to react .
The next day , when he wanted to watch what happens , he found that gases tfe he mix together in cans has been lost .
With dismay and angry he removed the covering metals and cans menggoyang-goyangkannya aloud .
Of the cap are tumbling splinters can of small creamy white and slippery .
This white splinters
5. plastic
Leo Hendrik Baekeland

Early in the 20th century , shellac ( shellac , a kind of like plastic hard and rigid ) widely used in industrial electronic to wrap perpheral electronic .
Material shellac ' re expensive because made of such a insects that live only in southeastern asia and should be diimport .
Therefore a chemist of belgian origin named leo hendrik baekeland ( 1863-1944 ) , in 1907 do research to create material alternative shellac minded because he will pay if can sell the material to industry electronic .
Instead , his research produced a pliable material that can be formed and sufficient endure the heat .
It gives name this material " bakelite " .
Immediately he realized material bakelite this had incredibly many uses .
Plastic material we know it today and ubiquitous been an bakelite derivative of this .
6. Pacemakers

Pacemakers found accidentally during an engineer wilson greatbatch , that was working making tools your heart , sound wrongful taking a electronic components of boxes these components .
When was working he needs a resistor worth 10,000 ohm , but he wrongful taking a resitor of the hold of 1 megaohm .
The result electronic circuit that while he do ticking during 1.8 millisecond then stop while for 1 seconds before starts beating back .
Diperhatikannya pattern is similar to heartbeats man , and the evolutionary pacemakers later discovered 

7. .Penicillin 
Alexander Fleming
Penicillin  antibiotic drug is most mostly consumed man .
Who think that penicillin found when alexander fleming ( 1881-1955 ) , a biological and a pharmaceutical chemist , without leave behind unintentionally equipment ex-coworker to go on vacation .
Keesokannya i came back , he found various fungi ( fungis ) peculiar in one of the formula ... .
Fungi this is what drove by days after through research further called penicillin , an antibiotic drug most widely used human until now .
