Ivan I. Mueller
Ivan Istvan Mueller (9 January 1930, Budapest – 12 April 2023, Bloomfield, Connecticut) was a Hungarian-American geodesist and professor at Ohio State University, a leading training center for geodesy in the USA. Biography Ivan I. Mueller and his wife Marianne were married in 1950. He graduated from the Technical University of Budapest (now renamed the Budapest University of Technology and Economics). He, with his family, left Hungary immediately after the Hungarian Revolution of 1956. He graduated from Ohio State University's Department of Geodetic Science and Surveying in 1960 with a Ph.D. in geodesy. His Ph.D. thesis is entitled ''The gradients of gravity and their applications in geodesy''. Upon the recommendation of his thesis advisor, Veikko Heiskanen, Mueller was appointed to a faculty position at Ohio State University and continued there until his retirement in 1992 as professor emeritus and department chair emeritus. Mueller shaped satellite geodesy from its beginn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budapest
Budapest (, ; ) is the capital and most populous city of Hungary. It is the ninth-largest city in the European Union by population within city limits and the second-largest city on the Danube river; the city has an estimated population of 1,752,286 over a land area of about . Budapest, which is both a city and county, forms the centre of the Budapest metropolitan area, which has an area of and a population of 3,303,786; it is a primate city, constituting 33% of the population of Hungary. The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century. The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time-of-flight
Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate). The traveling object may be detected directly (direct time of flight, dToF, e.g., via an ion detector in mass spectrometry) or indirectly (indirect time of flight, iToF, e.g., by light scattered from an object in laser doppler velocimetry). Overview In electronics, one of the earliest devices using the principle are ultrasonic distance-measuring devices, which emit an ultrasonic pulse and are able to measure the distance to a solid object based on the time taken for the wave to bounce back to the emitter. The ToF method is also used to estimate the electron mobility. Originally, it was designed for measurement of low-conductive thin films, later adjus ...

Geodesists
Geodesy ( ) is the Earth science of accurately measuring and understanding Earth's figure (geometric shape and size), orientation in space, and gravity. The field also incorporates studies of how these properties change over time and equivalent measurements for other planets (known as ''planetary geodesy''). Geodynamical phenomena, including crustal motion, tides and polar motion, can be studied by designing global and national control networks, applying space geodesy and terrestrial geodetic techniques and relying on datums and coordinate systems. The job title is geodesist or geodetic surveyor. History Definition The word geodesy comes from the Ancient Greek word ''geodaisia'' (literally, "division of Earth"). It is primarily concerned with positioning within the temporally varying gravitational field. Geodesy in the German-speaking world is divided into "higher geodesy" ( or ), which is concerned with measuring Earth on the global scale, and "practical geodesy" o ...

1930 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

The Vening Meinesz Medal is an annual award for outstanding research in geodesy. Background The medal, inaugurated in 1994, has been awarded by the European Geosciences Union (EGU) since 2004, and before that by the European Geophysical Society (EGS). The medal is named in honor of Felix Andries Vening Meinesz Felix Andries Vening Meinesz (30 July 1887 – 10 August 1966) was a Dutch geophysicist and geodesist. He is known for his invention of a precise method for measuring gravity (gravimetry). Thanks to his invention, it became possible to measure g ..., a Dutch geophysicists and geodesist, famous for his invention enabling precise measurements of gravity at sea.
