Harry Hammond Hess did many things in his lifetime. Hess’ most well known ideas was seafloor spreading. Hess used sound equipment that took measurements of the sea floor to help support his theory. The idea of seafloor spreading supported Alfred Wegener’s theory of continental drift. Harry Hess is a geologist who studied the ocean floor to develop the theory of seafloor spreading. Harry Hess was born on May 27, 1906, in New York City. He attended Yale and received a Bachelor of Science degree there in 1931. In 1932, Hess received a Ph.D from Princeton. He also became a professor at Princeton in 1934. He even got involved in NASA for a little bit of time. After a well spent life, Hess later died of a heart attack on August 26, 1969, in Massachusetts. …show more content…
The hypothesis explained the magnetic striping on the seafloor. Hess’ theory later supported Alfred Wegener’s theory of continental drift. The idea of seafloor spreading started when Hess was traveling, he would leave sound equipment on that took measurements of the sea floor. It appeared that there were mountains with flattened tops. He called these guyots. He believed that these were once volcanic mountains. His idea explained that hot magma would rise through the mantle and when the magma cooled, it would push tectonic plates
Jarrod J. Rein is an eighteen-year-old with dark brown hair and brown eyes to match the brown arid dirt of Piedmont, Oklahoma. His skin is a smooth warm tan glow that opposes his white smile making his teeth look like snow. Standing a great height of six foot exactly, his structure resembles a bear. He is attending Piedmont high school where he in his last year of high school (senior year). He is studying to be a forensics anthropologist. Also he is studying early in the field of anatomy to be successful in his profession. While not always on the rise for knowledge Jarrod’s swimming for his high school. In a sense it’s like you see double.
Oppenheimer was born on April 22, 1904, in New York City, New York. His mom, Ella Friedman, and dad, Julius S. Oppenheimer, a wealthy German Textile Merchant raised him as part of the Ethical Culture Society, an outgrowth of American Reform Judaism (www.atomicarchive.com) . Before all of his success as a student he got an illness which caused him to be held back from Harvard. He went to spend the summer at a dude ranch in New Mexico after waiting so long to get treatment . In 1922 he attended Harvard University, where he focused on Latin, Greek, Physics, and Chemistry.
For example when he writes about how the axes of each continent affects how well ideas and domesticated crops and animals flow or spread through the continent. This discussion had made lots of sense for me and is yet another idea that supports his theory. "At the one extreme was its rapid spread along east-west axes: from Southwest Asia both west to Europe and Egypt and east to the Indus Valley (at an average rate of about 0.7 miles per year); At the opposite extreme was its slow spread along north-south axes: at less than 0.5 miles per year, from Mexico northward to the U.S. Southwest; at less than 0.3 miles per year, " This example shows how east to west axes allow for a faster diffusion of crops and animals. But the north to south is very slow compared to the other. This helps explain why Eurasia had developed the quickest and the America and Africa lagged behind." For example, Portugal, northern Iran, and Japan, all located at about the same latitude but lying successively 4,000 miles east or west of each other, are more similar to each other in climate than each is to a location lying even a mere 1,000 miles due south." This line tells us why Eurasia was able to develop so fast. That is because it has an east to west axes which means animals and crops can more wildly thought the same land due to there being large amounts of land with the same latitude. While the Americas
What was Alfred Wegener’s hypothesis for continental drift, and why was his idea not accepted?
It is very hard and nearly impossible to find someone that had contributed to world’s science as much as Isaac Newton did. His works set the basis for modern world physics and his main work that was published in “Mathematical Principles of Natural Philosophy” is considered one of the most significant books that the world has seen. Newton was without doubt one of the most influential scientists in modern times and he is one of the examples of the scientific enlightenment that occurred in Europe in the seventeenth and eighteenth centuries. The evidence that support and served Newton has been collected by scientists and astronomers from different parts of the world. Newton’s work and contribution to the world wouldn’t be possible without the data that has been collected miles from his office in Cambridge. The crossing of ideas as part of the transporting world and the beginning of globally connected society had a major influence on the success of Newton’s Principia. Using Simon Schaffer’s article “Newton on the Beach: The Information Order of Principia Mathematica” and Roger Cotes’s “Preface to Newton’s Principia Mathematica” I will try to show how these crossings of ideas as part of a more globalized world were important aspect in the creation of this enlightened period.
One way Alfred Wegener proved his theory of continental drift was through land features. He realized that the coal fields, mountain ranges, and continents matched, and he attempted to put the continents together (like a puzzle). The second way Wegener proved his theory was through fossils. He found three fossils called Glossopteris (a fern like plant), Mesosaurus, and Lystrosaurus. Glossopteris was found in rocks in Africa, South America, Australia, India, and Antarctica, while Mesosaurus and Lystrosaurus were found on continents separated by oceans. Finally, the third way Wegener proved his theory continental drift was through climate zone. Wegener looked at climates from the past, and had found tropical plants living in Spitsbergen (an island in the arctic). He assumed that a island in the arctic, used to have a warm climate. In conclusion, the three ways Wegener proved his theory continental drift was through land features, fossils, and climate
In 1912, Alfred Wegener, a German scientist, was the first to notice this and develop the theory of plate tectonics. He noticed that the earth’s continents fit together almost like a jigsaw puzzle. This, combined with the fact that similar fossils and rock types are found on different continents separated by large bodies of water, helped him formulate his conjecture. He contended that the plates at one point formed one large continent called Pangea, which allowed like fossils and rock types to become closer together, which broke apart. Despite how well the continents fit together and the facts about the geology, the general public would not accept Wagener’s proposal. This is largely due to religious conflicts and the lack of evidence presented to them.
After graduation, he worked as a teacher at Berkeley for only a year. In 1942, he received citizenship for the United States since he was originally born in Canada. Throughout his career, he has worked as a professor in various universities. He taught at places such as Cornell University, University of Chicago, and Stanford University. Two times he was the chairman of the Chemistry Department in 1972 to 1974 and 1978 to 1979. He was also in the National Defense Research Committee while World War II was taking place.
It is theorized that convection heat transfer is what causes ocean floor spreading. New oceanic crust can be formed during volcanic activity where magma rises to the ocean floor from the cracks in the Earth’s mantle due to convection. Gradually the seafloor spreads away from the center of the cracks and leads to plate tectonic movement. Convection currents are created by heat that rises from Earth’s core through cracks in the mantle. The currents are trapped in the lithosphere in the seafloor. As the heat builds up the mantle cracks and magma rises through the cracks and pushes plates apart resulting in the creation of new seafloor which then leads to seafloor spreading and plate tectonic movement.
Gordon Parks was a photographer and humanitarian with a passion for documenting poverty, and civil rights in the second half of the 20th century. His signature style continues to be celebrated as one of the most iconic of the time.
James Fenimore Cooper is considered to be one of the first truly influential American writers, standing out from the heavily British-based literature of the time. Cooper was born in Burlington, New Jersey on September 15, 1789. His upbringing was thoroughly American, considering his mother, “Elizabeth Fenimore, was a member of a respectable New Jersey Quaker family, and his father, William, founded a frontier settlement at the source of the Susquehanna River (now Cooperstown, New York) and served as a Federalist congressman during the administrations of George Washington and John Adams” (Augustyn 98). Cooper was raised with opportunities to pursue a good education and he did not face the struggles of frontier life because he was the 11th out of twelve children (Augustyn 98). His family was situated in Albany, New York by the time he
Henry Gerber spent his life working to create an equal environment for himself and his fellow homosexuals.
Fred Hatch was an American agricultural inventor. It's hard to picture the farmscape without a silo or some type of farmyard, an old run down barn and especially a tower silo. When you think of barns you also should think of silos. The towering, vertical silos we imagine today, especially here located in the Midwest, are a true American innovation and go hand in hand with barns. Farm grain wasn't always stored in silos; it was stored in pits where farmers had to dig out which caused excess spoil in many instances. In 1873, silos were nonexistent.
John Brown University, founded in 1919, is located in the Northwest Arkansas Metropolitan Statistical Area. Made up of the cities of Fayetteville, Springdale, Rogers, and Bentonville, the area consistently ranks as a top 10 place to do business and live. In addition to the main campus, there are three educational facilities, one located in Fort Smith, a second in Little Rock, and the third in Rogers. The university was named after John E. Brown Sr. an entrepreneur, evangelist, and radio broadcaster. Brown wanted to provide a quality Christian education to students who would otherwise be unable to afford college, a tradition that the university continues today.
Alfred Lothar Wegener was born on November 1, 1880 and earned a Ph.D in astronomy in 1904. However Wegener had always been fascinated in climatology and meteorology. (According to ucmp.berkeley.edu) In the autumn of 1911, Wegener was browsing in Marburg university’s library and found a scientific paper that listed fossils of identical animals and plants found on opposite sides of the Atlantic ocean. With further searching he was able to prove that his theory of “Continental Drift” could have been true. The continental drift explained how parts of Earths crust could slowly drift atop a liquid core causing all continents were once formed as a single landmass to split apart . Although Wegener was the not the first scientist that all continents were connected at some point of time but, he was the first to prove it was plausible with evidence. This is why I agree that the continental drift is true, because of the fact that there were fossils of the same organisms on opposites sides of the Atlantic, same rock strata of South Africa and Brazil, and that fossils found in certain areas could ...
