Hans Albert Einstein ( /nˈstn, -ˈʃtn/ eyen-STYNE, -SHTYNE; May 14, 1904 – July 26, 1973) was a Swiss-American engineer and educator, the second child and first son of Albert Einstein and Mileva Marić. Hans A. Einstein was a professor of Hydraulic Engineering at the University of California, Berkeley, [1] and was recognized for his research on sediment transport. [2] His papers are held at the Water Resources Collections and Archives in the University of California, Riverside Libraries [3] and in the University of Iowa Libraries Special Collections and Archives.

Albert Einstein German-born physicist and developer of the theory of relativity

Albert Einstein was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics. His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.

Mileva Marić Serbian mathematician and wife of Albert Einstein

Mileva Marić, sometimes called Mileva Marić-Einstein or Mileva Marić-Ajnštajn, was a Serbian mathematician. She was the only woman among Albert Einstein's fellow students at Zürich's Polytechnic and was the second woman to finish a full program of study at the Department of Mathematics and Physics. Marić and Einstein were collaborators and lovers and had a daughter Lieserl in 1902, whose fate is unknown. They later had two sons, Hans Albert and Eduard.

Early life

Hans Albert Einstein was born on May 14, 1904 in Bern, Switzerland, where his father, Albert Einstein, worked as a clerk in the patent office. His father was of German-Jewish descent and his mother, Mileva Marić, Serbian-Orthodox. His younger brother, Eduard Einstein, was born in 1910 and died in 1965. The fate of his older sister, Lieserl Einstein, Albert Einstein's and Mileva Marić's first child, is unknown.[ citation needed ] Their parents divorced in 1919 after living apart for five years.[ citation needed ]

Bern Place in Switzerland

Bern or Berne is the de facto capital of Switzerland, referred to by the Swiss as their Bundesstadt, or "federal city". With a population of 142,493, Bern is the fifth-most populous city in Switzerland. The Bern agglomeration, which includes 36 municipalities, had a population of 406,900 in 2014. The metropolitan area had a population of 660,000 in 2000. Bern is also the capital of the canton of Bern, the second-most populous of Switzerland's cantons.

A patent office is a governmental or intergovernmental organization which controls the issue of patents. In other words, "patent offices are government bodies that may grant a patent or reject the patent application based on whether the application fulfils the requirements for patentability."

Career

Einstein followed his mother's and father's footsteps and studied at ETH, the Swiss Federal Institute of Technology, in Zurich, Switzerland. In 1926 he was awarded a diploma in civil engineering. From 1926 to 1930 he worked as a steel designer on a bridge project in Dortmund. In 1936 Hans Albert obtained the doctor of technical science degree. His doctoral thesis "Bed Load Transport as a Probability Problem" is considered the definitive work on sediment transport. [5]

ETH Zurich Swiss Federal Institute of Technology in Zurich

ETH Zurich is a science, technology, engineering and mathematics university in the city of Zürich, Switzerland. Like its sister institution EPFL, it is an integral part of the Swiss Federal Institutes of Technology Domain that is directly subordinate to Switzerland's Federal Department of Economic Affairs, Education and Research. The school was founded by the Swiss Federal Government in 1854 with the stated mission to educate engineers and scientists, serve as a national center of excellence in science and technology and provide a hub for interaction between the scientific community and industry.

Dortmund Place in North Rhine-Westphalia, Germany

Dortmund is, with a population of 586,600 (2017), the third largest city of Germany's most populous federal state of North Rhine-Westphalia after Cologne and Düsseldorf, and Germany's eighth largest city. It is the largest city of the Ruhr, Germany's largest urban area with some 5.1 million (2011) inhabitants, as well as the largest city of Westphalia. On the Emscher and Ruhr rivers, it lies in the Rhine-Ruhr Metropolitan Region and is considered the administrative, commercial and cultural centre of the eastern Ruhr.

Einstein's father, Albert, left Germany in 1933 to escape the virulently antisemitic Nazi threat. Heeding his father's advice, Einstein emigrated from Switzerland to Greenville, South Carolina, in 1938. He worked for the US Department of Agriculture, studying sediment transport from 1938 to 1943. He continued working for the USDA at the California Institute of Technology starting in 1943. In 1947 he took a position as associate professor of hydraulic engineering at the University of California, Berkeley. He advanced to full professor, and later professor emeritus. Einstein traveled the world to participate in hydraulic engineering conferences. He was at a symposium at Woods Hole in Massachusetts when he collapsed and died from heart failure on July 26, 1973. [6]

Hydraulic engineering sub-discipline of civil engineering concerned with the flow and conveyance of fluids, principally water and sewage

Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering.

Einstein was honored by a Guggenheim Fellowship (1953), research awards from the American Society of Civil Engineers (1959 and 1960), the Berkeley Citation from the University of California (1971), the Certificate of Merit from the U.S. Department of Agriculture (1971), and a certificate of recognition for more than twenty years of devoted and distinguished service to Applied Mechanics Reviews by the American Society of Mechanical Engineers (1972). [7]

Guggenheim Fellowships are grants that have been awarded annually since 1925 by the John Simon Guggenheim Memorial Foundation to those "who have demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts". The roll of Fellows includes numerous Nobel Laureates, Pulitzer, and other prize winners.

American Society of Civil Engineers professional association

The American Society of Civil Engineers (ASCE) is a tax-exempt professional body founded in 1852 to represent members of the civil engineering profession worldwide. Headquartered in Reston, Virginia, it is the oldest national engineering society in the United States. Its constitution was based on the older Boston Society of Civil Engineers from 1848.

Personal life

In 1927 Hans Albert Einstein married Frieda Knecht. Albert disapproved of Frieda much as his parents had of Mileva. Einstein and Frieda had four children:

Bernhard Caesar Einstein American physicist

Bernard Caesar Einstein was a Swiss-American physicist, the son of Hans Albert Einstein. Of the three known biological grandchildren of Albert Einstein, all sons of Hans, he was the only one to survive childhood.

Evelyn Einstein was the adopted daughter of Hans Albert Einstein, the son of Albert Einstein.

Frieda died in 1958, and Hans Albert later married neurochemist Elizabeth Roboz (1904–1995). [13]

Einstein was an avid sailor, frequently taking colleagues and family out for excursions on the San Francisco Bay. On his many field trips and academic excursions, he took thousands of pictures, many of which he developed himself and presented as slide shows. He also loved music, as denoted on his gravestone, and he played flute and piano. [14]

Einstein is a German-Jewish surname. People with the surname include:

Wash load as described by Hans Albert Einstein, "is if the sediment is added to the upstream end of a concrete channel and the channel is swept clean, and the sediment has not left any trace in the channel, its rate of transport need not be related to the flow rate." (2) The fine sediments that are in the wash load are generally smaller than .0625 mm, but what determines the wash load in reality is the relationship between the size of the bed load and the size of the particles that never settle in the "fine sediment load" or wash load.

Einstein family

The Einstein family is the family of the renowned physicist Albert Einstein (1879–1955). Einstein's great-great-great-great-grandfather, Jakob Weil, was his oldest recorded relative, born in the late 17th century, and the family continues to this day.

Einsteins awards and honors

During the year of 1922, Albert Einstein was awarded the 1921 Nobel Prize in Physics, "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". This refers to his 1905 paper on the photoelectric effect, "On a Heuristic Viewpoint Concerning the Production and Transformation of Light", which was well supported by the experimental evidence by that time. The presentation speech began by mentioning "his theory of relativity [which had] been the subject of lively debate in philosophical circles [and] also has astrophysical implications which are being rigorously examined at the present time".

The following outline is provided as an overview of and topical guide to Albert Einstein:
