Alfred Wegener: The German Meteorologist Who Theorized Pangea

albert wegener

There was some scattered support for his theory, but he passed away before the discoveries that would provide the mechanism for his theory and ultimate acceptance. Neither did the current data support the Copernican Model. In 1914 he was drafted into the German army, but was released from combat duty after being wounded, and served out the war in the Army weather forecasting service. In 1910, Wegener noticed the matching coastlines of the Atlantic continents -- they looked on maps like they had once been fit together. Wanting to return home as soon as possible, he insisted upon starting back to the base camp the very next morning. Being part of the Wedgewood-Darwin clan meant he would never have to worry about money. Faith is important to new scientific theories: faith that future scientists will address a theory's shortcomings.

During his childhood, Wegener's father ran an orphanage. In his book The Origin of Continents and Oceans, Wegener foretold plate tectonics and provided an explanation for continental drift.

Alfred Wegener's Continental Drift Theory

But they were unable to come up with a satisfactory model to explain how this giant landmass could become the modern continents positioned around the globe. Although his final expedition faced many difficulties and ended with his tragic death, it pursued an ambitious scientific program that served as a reference for subsequent international expeditions. Tenacious by nature, Wegener spent much of his adult life vigorously defending his theory of continental drift, which was severely attacked from the start and never gained acceptance in his lifetime. In the geological record he found corroborating evidence in the form of identical rock strata and fossil remains in eastern South America and western Africa and in other locations that would align if the continents fit together. We have an image in our minds as to what they looked like the last time we saw them, and they are much different. Wegener was an experienced polar explorer and many of his scientific goals can be traced to the early expeditions where he was already starting to pursue glaciological and meteorological questions.

Orthodox science at the time explained such cases by postulating that land bridges, now sunken, had once connected far-flung continents. This is certainly true of , one of the most important and far-ranging geological theories of all time; when first proposed, it was ridiculed, but steadily accumulating evidence finally prompted its acceptance, with immense consequences for geology, geophysics, oceanography, and paleontology. His research created a forward understanding of the technical and scientific logic before the shift was confirmed. His ideas were largely ignored at the time they were developed but today they are very well accepted by the scientific community. A Science Odyssey: People and Discoveries: Alfred Wegener Alfred Wegener 1880 - 1930 Alfred Wegener was born in Berlin in 1880, where his father was a minister who ran an orphanage. Further, we have to be prepared always for the possibility that each new discovery, no matter what science furnishes it, may modify the conclusions we draw.

Alfred Wegener: The German Meteorologist Who Theorized Pangea

On 6 January 1912, Wegener gave a courageous presentation at the annual meeting of the geological society Geologische Vereinigung at the Senckenberg Museum in Frankfurt. And the man who first proposed this theory was a brilliant interdisciplinary scientist, Alfred Wegener. Alfred Wegener left and an Innuit guide on 1 November 1930 during his final meteorological expedition in Greenland. He is well known as an expert of Greenland and for his close relations with the Inuit populations of Denmark and Greenland. The graphic below shows the striking distribution of fossils on the different continents. This flaw didn't stop universities such as Oxford from teaching Evolution as fact shortly after the publication of the Origin of Species. One of Alfred Wegener's critics, the geologist R.

Wegener, Galileo and Darwin The main problem with Wegener's hypothesis of Continental Drift was the lack of a mechanism. He accidentally became drawn into that topic by discovering evidence that might explain that phenomenon. Despite this, the book is received as both influential and controversial even today, due to the opposition divided amongst geologists regarding his geographic theories. Continental Drift Theory:The Fatal Flaw The picture painted of Alfred Wegener's contemporaries might not be fair. Like others before him, Wegener had been struck by the remarkable fit of the coastlines of South America and Africa.

At that time he held a position at the Hamburger Seewarte observatory, succeeding his father-in-law Wladimir Köppen as leader of the meteorological branch. This hole in Darwin's theory was plugged about 50 years later using the work of a Roman Catholic monk, Gregor Mendel. The students' minds would not be befogged. The son of an orphanage director, Wegener earned a Ph. Alfred Wegener knew that other people had made observations of the fit of the coastlines. In 1913 he married Else Köppen the daughter of his mentor Wladimir Köppen , with whom he had three children.

His few allies duToit and Holmes were no match for his many skeptics. The scientists of the time had scientifically valid reasons to doubt a moving earth. See how well it fits with Africa. The extreme cold turned back all but one of the 13 Greenlanders, but Wegener was determined to push on to the station, where he knew the supplies were desperately needed by Georgi and the other researchers. They opened Wegener to ridicule because they were orders of magnitude too weak. Stepping-stone islands would be a series of islands that traversed the ocean.

Alfred Wegener's Hypothesis About Pangaea

albert wegener

In 1912 a German meteorologist named Alfred Wegener 1880-1931 hypothesized a single proto-supercontinent that divided up into the continents we now know because of continental drift and plate tectonics. Wegener questioned why coal deposits, commonly associated with tropical climates, would be found near the North Pole and why the plains of Africa would show evidence of glaciation. What caused the extreme reaction? Ich glaube doch, Du hältst meinen Urkontinent für phantastischer als er ist und siehst noch nicht, daß es sich lediglich um Deutung des Beobachtungsmaterials handelt. Born on November 1, 1880, Alfred Lothar Wegener earned a Ph. From stretched, young crust in the middle of the ocean to seafloor spreading and plate tectonics would have been short mental leaps for a big thinker like Wegener.
