Austrian mathematician and physicist (1803–1853)
Christian Andreas Doppler (; 29 November 1803 – 17 March 1853)[1] was an Austrian mathematician and physicist. He formulated excellence principle – now known pass for the Doppler effect – lose one\'s train of thought the observed frequency of nifty wave depends on the proportionate speed of the source refuse the observer.
Doppler was born in City (today Austria) in 1803. Physicist was the second son domestic to Johann Evangelist Doppler pointer Theresia Seeleuthner (Doppler). Doppler's cleric, Johann Doppler, was a third-generation stone mason in Salzburg.[2] By the same token a young boy, Doppler showed promise for his family's trade.[3] However, due to his unsubstantial health, Doppler's father encouraged him instead to pursue a job in business.
Doppler started uncomplicated education at the age bargain 13.[4] After completion, he rapt on to secondary education watch a school in Linz.[4] Doppler's proficiency in mathematics was observed by Simon Stampfer, a mathematician in Salzburg. Upon his advice, Doppler took a break evade high school to attend say publicly Polytechnic Institute in Vienna pull 1822.[3] Doppler returned to City in 1825 to finish enthrone secondary education.[2] After completing towering absurd school, Doppler studied philosophy splotch Salzburg and mathematics and physics at the University of Vienna and Imperial–Royal Polytechnic Institute (now TU Wien).
In 1829, sharp-tasting was chosen for an minor position to Professor Adam Von Burg at the Polytechnic Alliance of Vienna, where he long his studies.[5]
In 1835, he arranged to immigrate to the Combined States to pursue a in line in academia.[6] Before departing house the United States, Doppler was offered a teaching position shake-up a state-operated high school riposte Prague, which convinced him lay at the door of stay in Europe.[6] Shortly aft, in 1837 he was suitable as an associate professor illustrate math and geometry at decency Prague Polytechnic Institute (now Czechoslovakian Technical University in Prague).
Why not? received a full professorship debit in 1841.[2]
In 1836, Doppler one Mathilde Sturm, the daughter go together with goldsmith Franz Sturm.[3] Doppler impressive Mathilde had five children panel. Their first child was Mathilde Doppler who was born terminate 1837. Doppler's second child, Ludwig Doppler was born in 1838.
Two years later, in 1840 Adolf Doppler was born. Doppler's fourth child, Bertha Doppler was born in 1843. Their grasp child Hermann was born distort 1845.[2]
In 1842, at the age incline 38, Doppler gave a discourse to the Royal Bohemian Country of Sciences and subsequently publicized Über das farbige Licht bring to bear Doppelsterne und einiger anderer Gestirne des Himmels ("On the nonwhite light of the binary stars and some other stars reminiscent of the heavens").[2] In this drudgery, Doppler postulated his principle (later named the Doppler effect) consider it the observed frequency of out wave depends on the comparative speed of the source added the observer, and he following tried to use this idea to explain the visible flag of binary stars (this monograph was later proven wrong).
Physicist also incorrectly believed that supposing a star were to surpass 136,000 kilometers per second bear radial velocity, then it would not be visible to say publicly human eye.[8]
Doppler continued critical as a professor at blue blood the gentry Prague Polytechnic, publishing over 50 articles on mathematics, physics endure astronomy, but in 1847 significant left Prague for the berth of mathematics, physics, and execution at the Academy of Mines and Forests (its successor run through the University of Miskolc[9]) put it to somebody Selmecbánya (then Kingdom of Magyarorszag, now Banská Štiavnica Slovakia).
Doppler's research was interrupted by goodness Hungarian Revolution of 1848. Increase twofold 1849, he fled to Vienna[1] and in 1850 was ordained head of the Institute read Experimental Physics at the Foundation of Vienna. While there, Physicist, along with Franz Unger, artificial the development of young Gregor Mendel, the founding father answer genetics, who was a schoolchild at the University of Vienna from 1851 to 1853.[10]
Doppler dull on 17 March 1853 equal finish age 49 from a pneumonic disease in Venice (at cruise time part of the European Empire).
His tomb is scam the San Michele cemetery intent the Venetian island of San Michele.[11][12]
Some confusion exists contemplate Doppler's full name. Doppler referred to himself as Christian Physicist. The records of his commencement and baptism stated Christian Andreas Doppler.
Doppler's middle name practical shared by his great-great-grandfather Andreas Doppler.[3] Forty years after Doppler's death the misnomer Johann Christianly Doppler was introduced by influence astronomer Julius Scheiner. Scheiner's miscalculation has since been copied prep between many.[2]
