Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, the use of quantitative methods for their analysis. The term geophysics sometimes refers only to geological applications: Earth's shape. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice. Although geophysics was only recognized as a separate discipline in the 19th century, its origins date back to ancient times; the first magnetic compasses were made from lodestones, while more modern magnetic compasses played an important role in the history of navigation. The first seismic instrument was built in 132 AD. Isaac Newton applied his theory of mechanics to the precession of the equinox. In the 20th century, geophysical methods were developed for remote exploration of the solid Earth and the ocean, geophysics played an essential role in the development of the theory of plate tectonics.
Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection. In Exploration geophysics, geophysical survey data are used to analyze potential petroleum reservoirs and mineral deposits, locate groundwater, find archaeological relics, determine the thickness of glaciers and soils, assess sites for environmental remediation. Geophysics is a interdisciplinary subject, geophysicists contribute to every area of the Earth sciences. To provide a clearer idea of what constitutes geophysics, this section describes phenomena that are studied in physics and how they relate to the Earth and its surroundings. In Geophysics, principles of Physics are applied to study the "Interior" of the Earth. Depending on the problem under study, one has to decide. E.g. for ground water surveys, Electrical method is helpful. For mineral deposits, one can adopt Gravity and/or Magnetic surveys. For Oil & Natural Gas, one has to carry out Gravity, Magnetic surveys to get rough idea about structure of rock formations.
If the desired structure is existing, for detailed study of rock formations, one has to carry out Seismic and/or Magneto-telluric surveys. The gravitational pull of the Moon and Sun give rise to two high tides and two low tides every lunar day, or every 24 hours and 50 minutes. Therefore, there is a gap of 12 hours and 25 minutes between every high tide and between every low tide. Gravitational forces make rocks press down on deeper rocks, increasing their density as the depth increases. Measurements of gravitational acceleration and gravitational potential at the Earth's surface and above it can be used to look for mineral deposits; the surface gravitational field provides information on the dynamics of tectonic plates. The geopotential surface called; the geoid would be the global mean sea level if the oceans were in equilibrium and could be extended through the continents. The Earth is cooling, the resulting heat flow generates the Earth's magnetic field through the geodynamo and plate tectonics through mantle convection.
The main sources of heat are the primordial heat and radioactivity, although there are contributions from phase transitions. Heat is carried to the surface by thermal convection, although there are two thermal boundary layers – the core-mantle boundary and the lithosphere – in which heat is transported by conduction; some heat is carried up from the bottom of the mantle by mantle plumes. The heat flow at the Earth's surface is about 4.2 × 1013 W, it is a potential source of geothermal energy. Seismic waves are vibrations that travel along its surface; the entire Earth can oscillate in forms that are called normal modes or free oscillations of the Earth. Ground motions from waves or normal modes are measured using seismographs. If the waves come from a localized source such as an earthquake or explosion, measurements at more than one location can be used to locate the source; the locations of earthquakes provide information on mantle convection. Recording of seismic waves from controlled sources provide information on the region that the waves travel through.
If the density or composition of the rock changes, waves are reflected. Reflections recorded using Reflection Seismology can provide a wealth of information on the structure of the earth up to several kilometers deep and are used to increase our understanding of the geology as well as to explore for oil and gas. Changes in the travel direction, called refraction, can be used to infer the deep structure of the Earth. Earthquakes pose a risk to humans. Understanding their mechanisms, which depend on the type of earthquake, can lead to better estimates of earthquake risk and improvements in earthquake engineering. Although we notice electricity during thunderstorms, there is always a downward electric field near the surface that averages 120 volts per meter. Relative to the solid Earth, the atmosphere has a net positive charge due to bombardment by cosmic rays. A current of about 1800 amperes flows in the global
Anton Resch was a former Luftwaffe fighter ace and recipient of the Knight's Cross of the Iron Cross during World War II. The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership. Anton Resch was credited with 91 victories, he gained his first Soviet victory Il-2 Sturmovik over the Eastern Front on 21 October 1943. On 27 January 1944 he was wounded by Russian fighters, but returned to duty in June of that same year. On 26 August he recorded seven Soviet victories and other seven on 31 August 1944. On 10 September 1944 was again wounded by Slovak insurgency flak. After the war Resch spent many years in Soviet captivity. Anton Resch was credited with 91 victories, 64 of them over the Eastern Front, including 24 Il-2 Sturmoviks and other 27 victories over the Western Front.

The Wynne Theater was a movie theater on 54th and Wynnefield Avenue in the Wynnefield neighborhood of Philadelphia, United States. Considered to be a Philadelphia "Landmark," it was built from 1927-1928 by Hoffman-Henon Co. for the Stanley Company of America. The theater was named for the attending physician of William Penn.. It could seat 1,663 people. In 1955 the theater was taken over by the Uhr family of South Philadelphia; the building was renovated and renamed the Wynne Cateres where it became a popular place for parties and hosting. The last owner of the property died in 1993 and with no one left to claim the space, the building has remained unoccupied. In 2008 the Community Design Collaborative awarded a service grant to the Wynnefield Overbrook Revitalization Corporation to be put towards the creation of plans for the redevelopment of the Wynne Theater complex. A report completed in 2010 presented several options, with community members favoring the property's conversion into a community center.
This would see the unsafe and damaged areas of theater replaced, as well as the restoration of the historic headhouse, to create a large community hall above ground level parking. The project's total cost was estimated at $6.7 million but as of January 2012 no work has been initiated and a developer has yet to be found to carry out the proposal. In December 2011, the Provenance Architectural Salvage in Philadelphia removed and sold the building's neon art deco letters, lighting fixtures from the outside of the building, owing to concern by the Department of License and Inspections that these were a safety hazard; the marquee letters were produced locally in nearby Lansdale.
