By example, MacPhearais ( Mac+Pearas = son of Pierce ) has been anglicized as Corish , and MacAonghais has been anglicized as MacAngus , MacInnis , MacInnes , Innis , Innes , and Guinness . As with Gaelic and Germanic surnames, Welsh surnames and Cornish surnames had originally been mostly patronymic , though others contained toponymic elements, or were derived from trades, or personal characteristics. Surnames which remained fixed across generations, passed down along
1060-600: A fluidity in how families chose to spell their names. Legal problems caused by spelling variations in Surnames were addressed by the Land Purchases Act. This Act established the principle of idem sonans, that is if differently spelled names "sounded the same," a claim of an unbroken line of ownership could be acknowledged. Since preserving the name's sound was legally important, common forms of Surname changes involved spelling adaptations that helped English readers replicate

#17328369069422332-749: The Cold War . German Americans are the largest ethnic group in the USA numbering at almost 50 million or roughly 1/6th of US population. Immigration from Germany can be traced back to 1608 (Jamestown, VA), but migration was highest between the mid 19th century and early 20th century. From 1876 to 1923, Germany was the largest source of US Immigrants. From 1923 to 1970, it was the 2nd largest source of US Immigrants after Italy. A formal immigration process channeling immigrants through Ellis Island only began in 1892. Immigrants arriving prior to this, did not receive official immigration papers documenting their names. This created

In contrast, translations of the Old Testament traditionally use the original names, more or less faithfully transliterated from the original Hebrew. Transatlantic explorers such as Zuan Chabotto and Cristoforo Colombo became popularly known as John Cabot and Christopher Columbus; English-speakers anglicized and Latinized
2650-560: The Timok Valley through the Nisevac Gorge. Milankovitch, who liked this idea very much, soon drew up structural calculations for all the bridges with reinforced concrete arches. While studying the works of the contemporaneous climatologist Julius von Hann , Milanković noticed a significant issue, which became one of the major objects of his scientific research: a mystery ice age . The idea of possible astronomically-related climate changes

His next paper was entitled " Distribution of the sun radiation on the earth's surface " and was published on June 1913. In December of that year, this paper was read by Wilhelm Wien , and was soon published in the German journal Annalen der Physik . He correctly calculated
2862-660: The "Canon". The manuscript was submitted to print on 2 April 1941 – four days before the attack of Nazi Germany and its allies on the Kingdom of Yugoslavia . In the bombing of Belgrade on 6 April 1941, the printing house where his work was being printed was destroyed; however, almost all of the printed sheet paper remained undamaged in the printing warehouse. After the successful occupation of Serbia on 15 May 1941, two German officers and geology students came to Milanković in his house and brought greetings from Professor Wolfgang Soergel [ de ] of Freiburg . Milanković gave them
2968-504: The 1940s, automobile registration documents, along with widespread implementation of social security, played an important role in stabilizing American surnames by legally documenting most of the US population's names. Italian surnames were often anglicized in the United States: for example, the i-ending of a number of Italian names becomes y , e , or ie . When Dutch immigrants arrived in

Milanković became convinced that the continents 'float' on a somewhat fluid subsurface and that the positions of the continents with respect to the axis of rotation affect the centrifugal force of the rotation and can throw the axis off balance and force it to move. Wegener's tragedy additionally motivated Milankovich to persevere in solving

That same year, he was elected a corresponding member of the Serbian Royal Academy of Sciences in Belgrade and the Yugoslav Academy of Science and Arts in Zagreb. As a consequence of the Russian Civil War , with the arrival of Russian scientists – emigrants, the personnel base of the Faculty of Philosophy at the University of Belgrade was expanded. Thus, from 1920 Anton Bilimovich (1879–1970),

During the time in which there were large influxes of immigrants from Europe to the United States and United Kingdom during the 19th and 20th centuries, the given names and surnames of many immigrants were changed. This became known colloquially as the " Ellis Island Special ", after
4028-539: The Sun at the center of his theory, as the only source of heat and light in the Solar System. He considered three cyclical movements of the Earth: eccentricity , axial tilt , and precession . Each cycle works on a different time-scale and each affects the amount of solar energy received by the planets. Such changes in the geometry of an orbit lead to the changes in the insolation – the quantity of heat received by any spot at

Traditionally common Christian given names could be substituted: such as James for the etymologically connected Jacques. Alternatively phonetical similarities, such as Joe for Giò (Giovanni or Giorgio); or abbreviation, Harry for Harilaos, or Ricky for Enrique (Henry), as common in Spanish, instead of for (Ricardo) Richard as in English. The anglicisation of

4558-532: The United States, often their names got changed. This was either done on purpose, to make the name easier to write and remember, or by accident because the clerk didn't know how to spell the name and wrote it down phonetically. Coastal Salish people were often given "Boston names" by early European settlers. These English names often had similar sounds to original Lushootseed names. When Lushootseed names were integrated into English, they were often recorded and pronounced very differently. An example of this

By example, MacAoidh (son of Hugh ) becomes MicAoidh ( sons of Hugh ) and Clann MhicAoidh ( literally children/descendants of Hugh ). The Jacksons in English (with Jack being derived from John) would in Gaelic be rendered a' MhicSheain (
7844-407: The planet Mars". He knew the size of Mars and its distance from the Sun, but also that it has a similar rotation speed and axis orientation as Earth. Milanković calculated that the average temperature in the lower layers the atmosphere on Mars is −45 °C (−49 °F) and the average surface temperature is −17 °C (1 °F). Also, he concluded that: "This large temperature difference between
7950-406: The position of professor of celestial mechanics and the history of astronomy at the University of Belgrade. In the same year, he published his last work, which is not from the natural sciences, but from his original profession of structural engineering. The paper was titled The Tower of Babel of modern technology . Milankovitch in this work calculated the highest building possible on our Earth. He
8056-422: The problem of polar wandering. Milanković began working on the problem of the shape of the Earth and the position of the Earth's poles in 1932 and 1933 at the suggestion of Alfred Wegener. The Earth as a whole he considered as a fluid body , which in the case of short-duration forces behaves as a solid body , but under an influence behaves as an elastic body . Using vector analysis he made a mathematical model of
8162-520: The qualification to teach mathematics and physics at secondary schools and went into the teaching profession. On 17 March 1875 Finger received his doctorate at the University of Vienna , in 1876 he was qualified for the subject of analytical mechanics . In 1897 Finger published “On the internal virial of an elastic body ". Finger was from 1888 to 1890 the Dean of the Chemical School, and from 1890 to 1891 he
8268-402: The records of Earth's magnetic field in rocks over geological time. Paleomagnetic evidence, both reversals and polar wandering data, led the revival of the theories of continental drift and its transformation into plate tectonics . To collect his scientific work on the theory of solar radiation that was scattered in many books and papers, Milanković began his life's work in 1939. This tome
8374-703: The same year, he became a member of the Italian Institute of Paleontology . In November 1954, fifty years after receiving his original diploma, he received the Golden Doctor's diploma from the Technical University of Vienna. In 1955, he was also elected to the German Academy of Naturalists "Leopoldina" in Halle , Saxony-Anhalt . At the same time, Milankovitch began publishing numerous books and textbooks on
8480-491: The secular pole trajectory depends only on the configuration of the terrestrial outer shell and the instantaneous pole position on it, more precisely on geometry of the Earth mass. On this basis he could calculate the secular pole trajectory. Also, based on Milanković's model, the continental blocks sink into their underlying "fluidal" base, and slide around, 'aiming to achieve' isostatic equilibrium . In his conclusion about this problem, he wrote: For an extraterrestrial observer,
8586-451: The sense of revolution of the planet, and the orbital ellipse parameter; the second specifies the axis of the orbit in its plane and the orbital eccentricity. By applying those vectors he significantly simplified the calculation and directly obtained all the formulas of the classical theory of secular perturbations . Milanković, in a simple but original manner, first deduced Newton's law of gravitation from Kepler's laws. Then Milanković treated
8692-421: The six parts of the book are: During the German occupation of Serbia from 1941 to 1944, Milanković withdrew from public life and decided to write a "history of his life and work" going beyond scientific matters, including his personal life and the love of his father who died in his youth. His autobiography would be published after the war, entitled "Recollection, Experiences and Vision" in Belgrade in 1952. After
8798-477: The smith ) were anglicized as McGowan , Gowan , McGavin , and Gavin . In surnames which had been prefixed Mac (which includes most Manx surnames), the final hard c sound remained when the Mac was removed. As Gaelic spelling rules required the first letter of a name preceded by Mac or Nic to be lenited (providing it was a consonant other than l, n, or r, which are not generally lenited in Gaelic, or c or g; although in
8904-406: The sons of John ). Over the centuries, under the influence of post- Medieval English practice , this type of surname has become static over generations, handed down the male lineage to all successive generations so that it no longer indicates the given name of a holder's father any more than the suffix -son on a Germanic language surname does today. Among English-speaking peoples of Gaelic heritage,
9010-1259: The spelling (Benoît, pronounced French pronunciation: [bənwa] , became Benway, or Bennett / b ɛ n ˈ ɔɪ t / ). Some Greek names are anglicized using the etymologically related name: Agni: Agnes; Alexandros/Alexis: Alexander/Alex; Alexandra: Alexandra/Alex; Andreas: Andrew; Christophoros: Christopher; Evgenios/Evgenis: Eugene/Gene; Eleni: Helen; Georgios/Yorgos: George; Ioannis/Yannis: John; Irini: Irene; Katharini: Catherine/Kate; Markos: Mark; Michail/Michalis: Michael; Nikolaos: Nicholas; Pavlos: Paul; Petros: Peter; Stephanos: Stephen; Theodoros: Theodore/Ted; and so on. Besides simple abbreviation or anglicisation of spelling, there are some conventional English versions of or nicknames for Greek names which were formerly widely used and are still encountered: Hundreds of Spiritual Christian Doukhobors who migrated from Russia to Canada from 1899 to 1930, changed their surnames. Genealogist Jonathan Kalmakoff posted comprehensive lists for Many descendants of Spiritual Christians from Russia in California, whose parents immigrated to Los Angeles (1904–1912), hid their family surnames due to real and perceived ethnic discrimination during
9116-517: The surface of a planet. These orbital variations , which are influenced by gravity of the Moon , Sun, Jupiter , and Saturn , form the basis of the Milankovitch cycle . Between 1925 and 1928 Milanković wrote the popular-science book Through Distant Worlds and Times in the form of letters to an anonymous woman. The work discusses the history of astronomy, climatology and science via a series of imaginary visits to various points in space and time by
9222-412: The temperature in the outer limit of the atmosphere +25 °C (77 °F), the upper layer +54 °C (129 °F), the middle layer +70 °C (158 °F) and the lower layer of the atmosphere +80 °C (176 °F) as well as a ground temperature of +97 °C (207 °F). In his literary work Through Distant Worlds and Times , he described of Venus in the following words: Here we are in
9328-405: The temple of Isis and Osiris, more magnificent than Schinkel himself imagined. From its huge dome, covered with a gently mother-of-pearl mosaic, a white mysterious light spills over the interior of this home. That dome, that's the sky of Venus. The Sun is never visible on it, only the Sun's silvery glow. Not a single star twinkles in this sky; no messenger of the universe reaches this sanctuary...What
9434-521: The time ( Gunz , Mindel , Riss and Würm glaciation). Köppen felt that Milanković's theoretical approach to solar energy was a logical approach to the problem. His solar curve was introduced in a work entitled " Climates of the geological past ", published by Wladimir Köppen and his son-in-law Alfred Wegener in 1924. In September of that year, he attended the lecture given by Alfred Wegener at Congress of German Naturalist in Insbruck . That same year, he
9540-515: The title Mathematische Grundlagen der kosmischen Strahlungslehre that he sent to his mentor Professor Czuber in Vienna at the end of 1917. Czuber contacted a publishing house in Leipzig , but since there was a shortage of paper in early 1918, the printing of the book was cancelled. Meanwhile, Milanković found a regular job in 1918 as an engineer in a construction company in Budapest. After the Great War ,
9646-653: The title "Canon of Insolation of the Ice-Age Problem" in 1969 by the Israel Program for Scientific Translations, and was published by the U.S. Department of Commerce and the National Science Foundation in Washington, D.C. In the beginning, recognition came slowly, but later, the theory was proven to be accurate. Project CLIMAP (Climate: Long Range Investigation, Mapping and Production) finally resolved
9752-566: The two-body and the many-body problems of celestial mechanics. He applied vector calculus from quantum mechanics to celestial mechanics. Meanwhile, in 1936 he attended the Third symposium of the International Union for Quaternary Research (INQUA) in Vienna. In the period from 1935 to 1938 Milanković calculated that ice cover depended on changes in insolation. He succeeded in defining the mathematical relationship between summer insolation and
9858-423: The use of Nic as a prefix for daughters has been replaced by Mac , regardless of sex (as per Geraldine McGowan , Alyth McCormack , and Sarah McLachlan ). Wives also began to take on the surnames of their husbands. Another common pattern of surname was similar to that preceded by Mac/Nic, but instead was preceded by Ó or Ui, signifying a grandchild or descendant. Not all Gaelic surnames signified relationship to
9964-517: The war, in 1947, Milanković's only son emigrated from the new communist Yugoslavia via Paris , London and Egypt to Australia . Milanković would never see his son again and the only way of correspondence between them would be through letters. Milanković was vice president of the Serbian Academy of Sciences (1948–1958). In 1948, the General Assembly of the International Astronomical Union
10070-410: Was criticized from the beginning. Milankovitch's trajectory of polar wandering was a topic of discussion after World War II. In the 1950s, paleomagnetic data showed different results than Milankovitch's theoretical numerical values for polar wandering trajectory. However, development of the new scientific discipline in geophysics known as palaeomagnetism led to the key evidence on the basis of studying
10176-651: Was edited by Köppen himself. That same year, Milanković asked his colleague and friend, Vojislav Mišković , to collaborate in the work and calculate astronomical values based on the Le Verrier method. Mišković was a well-established astronomer from the Nice Observatory , who became the head of the Astronomical Observatory of the University of Belgrade and a professor of Theoretical and Practical Astronomy. After almost three years, Mišković and his staff completed
10282-588: Was elected a full member of the Serbian Royal Academy of Sciences. The Meteorological service of the Kingdom of Yugoslavia became a member of International Meteorological Organization – IMO (founded in Brussels in 1853 and in Vienna in 1873) as a predecessor of present World Meteorological Organization , WMO. Milanković served as a representative of the Kingdom of Yugoslavia there for many years. Milanković put
10388-505: Was entitled "Canon of Insolation of the Earth and Its Application to the Problem of the Ice Ages", which covered his nearly three decades of research, including a large number of formulas, calculations and schemes, but also summarized universal laws through which it was possible to explain cyclical climate change – his namesake Milankovitch cycles . Milanković spent two years arranging and writing
10494-458: Was first considered by astronomers ( John Herschel , 1792–1871) and geologists ( Louis Agassiz , 1807–1873). Milanković studied the works of Joseph Adhemar whose pioneering theory on the astronomical origins of ice ages were formally rejected by his contemporaries and the amateur scientist James Croll (1821-1890), whose work was effectively forgotten after initial acceptance by contemporaries such as Charles Darwin . Despite having valuable data on
10600-774: Was held in Zürich . Milankovich is listed as a member of Commission 7 for Celestial Mechanics, and “V. Mishkovitch” as member of Commission 19 for Latitude Variation and Commission 20 for Minor Planets. For a short period, he was the head of the Belgrade Observatory (1948 - 1951). At that time, the Cold War between nuclear powers began. In 1953, he was at the Congress of the International Union for Quaternary Research (INQUA) held in Rome . In
10706-527: Was inspired by work of Pieter Bruegel the Elder 's Tower of Babel (older version in Vienna). The building would have a base radius of 112.84 km and a height of 21646 m. Since the building penetrates the Earth 1.4 km, it would have a height of 20.25 km above the Earth's surface. At the very top, there would be a wide platform for a meteorological and astronomical station. In September 1957, Milutin suffered
10812-481: Was ready to start the realization of the mathematical description of climate of the Earth in the past. Milanković spent 100 days doing the calculations and prepared a graph of solar radiation changes at geographical latitudes of 55°, 60° and 65° north for the past 650,000 years. Milankovitch, in his early works, used the astronomical values of Stockwell - Pilgram . These curves showed the variations in insolation which correlated with four Alpine glaciations known at
10918-426: Was skeptical that it could have complex life forms as well and vegetation . In addition to considering Mars, he dealt with the climatic conditions prevailing on Venus and Mercury . According to his own words, Milankovitch did not know the speed of rotation of Venus, the orientation of the axis, as well as the thickness and composition of the atmosphere . He was awere with Schiaparelli's suggestion that Venus has
11024-434: Was sometimes anglicized as Fahey or Fay , identically to the given name; Ó Leannáin and Ó Lionáin have both been anglicized as Lennon ; Ó Ceallaigh and Ó Cadhla have been anglicized as Kelly ). Where they were retained, Mac was often rendered Mc , M', or Mag- (the last is seen in renderings such as Maguire for Mac Uidhir ) and Ó/Ui became O' . MacGhobhainn , Mac a'Ghobhainn and Mac Gabhainn ( son of
11130-405: Was the masterpiece of strict logic, without any extra word, without any error." After graduating and spending his obligatory year in military service, Milanković borrowed money from an uncle to pay for additional schooling at TU Wien in engineering. He researched concrete and wrote a theoretical evaluation of it as a building material. At age twenty-five, his PhD thesis was entitled Contribution to
11236-415: Was −53.8 °C (−64.8 °F). At noon, it rises on +97 °C (207 °F), only to reach its maximum value one Earth day later +100.5 °C (212.9 °F). At sunset, the temperature drops −8.8 °C (16.2 °F). According to Milankovitch, a sudden cooling occurs during the night. From 1912 to 1917, he wrote and published seven papers on mathematical theories of climate both on the Earth and on
