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 the city of 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 Bro ...

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, st ...

Physics
Physics is the scientific study of matter, its Elementary particle, 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." It is one of the most fundamental scientific disciplines. "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 physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor's Degree
A bachelor's degree (from Medieval Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on the 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] |

New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States.

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 were separately founded: the University of the City of New York School of Civil Engineering and Architecture, which evolved into the NYU College of Engineering; and the Brooklyn Collegiate and Polytechnic Institute, which evolved into Polytechnic Institute. In 1973, Polytechnic Institute acquired the College of Engineering from NYU, but in 2008, Polytechnic was absorbed by NYU to become its new engineering school. In 2015 NYU renamed the engineering school 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hawkesbury, Ontario
Hawkesbury is a town along the Ottawa River in the United Counties of Prescott and Russell in Eastern Ontario, Canada. Hawkesbury is the third most bilingual town in Ontario, with about 70% of its inhabitants being fluent in English and French. Franco-Ontarians make up 89% of the population.

Herman Francis Mark
Herman Francis Mark (born Hermann Franz 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 Mark was born in Vienna in 1895, the son of Hermann Carl Mark, a physician, and Lili Mueller. Mark's father was Jewish, but converted to Christianity (Lutheran Church) upon marriage. Several early stimuli apparently steered Herman Mark to science. He was ...

Anschluss
The (, or , ), also known as the (, ), was the annexation of the Federal State of Austria into Nazi Germany on 12 March 1938. The idea of an (a united Austria and Germany that would form a "German Question, Greater Germany") arose after the unification of Germany, 1871 unification of Germany excluded Austria and the German Austrians from the Prussian-dominated German Empire. It gained support after the Austria-Hungary, Austro-Hungarian Empire fell in 1918. The new Republic of German-Austria attempted to form a union with Germany, but the 1919 Treaty of Saint-Germain-en-Laye (1919), Treaty of Saint Germain and Treaty of Versailles forbade both the union and the continued use of the name "German-Austria" (); they also stripped Austria of some of its territories, such as the Sudetenland. This left Austria without most of the territories it had ruled for centuries and amid economic crisis. By the 1920s, the proposal had strong support in both Austria and Germany, particularly ...
