Hans Mark
Hans Michael Mark (June 17, 1929 – December 18, 2021) was a German-born American government official who served as Secretary of the Air Force and as a Deputy Administrator of NASA. He was an expert and consultant in aerospace design and national defense policy. Mark retired from the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin's Cockrell School of Engineering in July 2014. Early life and career Mark was born in Mannheim, Baden, Germany. He lived in Vienna for a time before escaping the Nazi ''Anschluss'' via Switzerland. Before the collapse of France the Mark family moved to London. Mark's father, Herman Francis Mark, a prominent polymer chemist, secured a position with a Canadian paper company and left before the family could accompany him. Finally, in late 1939, his family joined him in Hawkesbury, Ontario. About a year later the family moved to the United States, settling in the Flatbush section of Brooklyn, New Yo ...

Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Bachelor's Degree
A bachelor's degree (from Middle Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, certain bachelor's degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor's degree is a prerequisite for further courses such as a master's or a doctorate. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately). However, some qualifications titled bachelor's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stuyvesant High School
Stuyvesant High School (pronounced ), commonly referred to among its students as Stuy (pronounced ), is a State school, public university-preparatory school, college-preparatory, Specialized high schools in New York City, specialized high school in New York City, United States. Operated by the New York City Department of Education, these specialized schools offer Tuition payments, tuition-free accelerated academics to city residents. Stuyvesant was established as an all-boys school in the East Village, Manhattan, East Village of Manhattan in 1904. An entrance examination was mandated for all applicants starting in 1934, and the school started accepting female students in 1969. Stuyvesant moved to its current location at Battery Park City in 1992 because the student body had become too large to be suitably accommodated in the original campus. The old building now houses several high schools. Admission to Stuyvesant involves passing the Specialized High Schools Admissions Test. Eve ...

New York University Tandon School Of Engineering
The New York University Tandon School of Engineering (commonly referred to as Tandon) is the engineering and applied sciences school of New York University. Tandon is the second oldest private engineering and technology school in the United States. The school dates back to 1854 when its predecessor institutions, the University of the City of New York School of Civil Engineering and Architecture and the Brooklyn Collegiate and Polytechnic Institute, were founded. The school was renamed in 2015 in honor of NYU Trustees Chandrika and Ranjan Tandon following their donation of $100 million to the school. The school's main campus is in Brooklyn's MetroTech Center, an urban academic-industrial research park. It is one of several engineering schools that were founded based on a European polytechnic university model in the 1800s, in response to the increasing industrialization of the United States.

Herman Francis Mark
Herman Francis Mark (May 3, 1895, Vienna – April 6, 1992, Austin, Texas) was an Austrian-American chemist regarded for his contributions to the development of polymer science. Mark's x-ray diffraction work on the molecular structure of fibers provided important evidence for the macromolecular theory of polymer structure. Together with Houwink he formulated an equation, now called the Mark–Houwink or Mark–Houwink–Sakurada equation, describing the dependence of the intrinsic viscosity of a polymer on its relative molecular mass (molecular weight). He was a long-time faculty at Polytechnic Institute of Brooklyn. In 1946, he established the '' Journal of Polymer Science''. Biography Early life ''Hermann Franz'' Mark was born in Vienna in 1895, the son of Hermann Carl Mark, a physician, and Lili Mueller. Mark's father was a Jew who converted to Christianity (Lutheran Church) upon marriage. Several early stimuli apparently steered Herman Mark to science. He was greatly infl ...

Anschluss
The (, or , ), also known as the (, en, Annexation of Austria), was the annexation of the Federal State of Austria into the German Reich on 13 March 1938. The idea of an (a united Austria and Germany that would form a " Greater Germany") began after the unification of Germany excluded Austria and the German Austrians from the Prussian-dominated German Empire in 1871. Following the end of World War I with the fall of the Austro-Hungarian Empire, in 1918, the newly formed Republic of German-Austria attempted to form a union with Germany, but the Treaty of Saint Germain (10 September 1919) and the Treaty of Versailles (28 June 1919) forbade both the union and the continued use of the name "German-Austria" (); and stripped Austria of some of its territories, such as the Sudetenland. Prior to the , there had been strong support in both Austria and Germany for unification of the two countries. In the immediate aftermath of the dissolution of the Habsburg monarchy—with ...
