Gravity assist
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing - by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. The ``assist ''is provided by the motion of the gravitating body as it pulls on the spacecraft. The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon and it was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes' notable flybys of Jupiter and Saturn.
Nonprofit organization
Capacity building is an ongoing problem experienced by NPOs for a number of reasons. Most rely on external funding (government funds, grants from charitable foundations, direct donations) to maintain their operations and changes in these sources of revenue may influence the reliability or predictability with which the organization can hire and retain staff, sustain facilities, create programs, or maintain tax-exempt status. For example, a university that sells research to for-profit companies may have tax exemption problems. In addition, unreliable funding, long hours and low pay can result in employee retention problems. During 2009, the US government acknowledged this critical need by the inclusion of the Nonprofit Capacity Building Program in the Serve America Act. Further efforts to quantify the scope of the sector and propose policy solutions for community benefit were included in the Nonprofit Sector and Community Solutions Act, proposed during 2010.
Force
It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.
Jupiter
Since 1973 a number of automated spacecraft have visited Jupiter, most notably the Pioneer 10 space probe, the first spacecraft to get close enough to Jupiter to send back revelations about the properties and phenomena of the Solar System's largest planet. Flights to other planets within the Solar System are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v. Entering a Hohmann transfer orbit from Earth to Jupiter from low Earth orbit requires a delta-v of 6.3 km/s which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. Gravity assists through planetary flybys can be used to reduce the energy required to reach Jupiter, albeit at the cost of a significantly longer flight duration.
Stability of the Solar System
Another project involved constructing the Digital Orrery by Gerry Sussman and his MIT group in 1988. The group used a supercomputer to integrate the orbits of the outer planets over 845 million years (some 20 per cent of the age of the Solar System). In 1988, Sussman and Wisdom found data using the Orrery which revealed that Pluto's orbit shows signs of chaos, due in part to its peculiar resonance with Neptune.If Pluto's orbit is chaotic, then technically the whole Solar System is chaotic, because each body, even one as small as Pluto, affects the others to some extent through gravitational interactions.
Discovery of Neptune
The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet were made on the night of September 23 -- 24, 1846, at the Berlin Observatory, by astronomer Johann Gottfried Galle (assisted by Heinrich Louis d'Arrest), working from Le Verrier's calculations. It was a sensational moment of 19th century science and dramatic confirmation of Newtonian gravitational theory. In François Arago's apt phrase, Le Verrier had discovered a planet ``with the point of his pen ''.
Estonia
Since re-establishing independence, Estonia has styled itself as the gateway between East and West and aggressively pursued economic reform and integration with the West. Estonia's market reforms put it among the economic leaders in the former COMECON area.[citation needed] In 1994, based on the economic theories of Milton Friedman, Estonia became one of the first countries to adopt a flat tax, with a uniform rate of 26% regardless of personal income. In January 2005, the personal income tax rate was reduced to 24%. Another reduction to 23% followed in January 2006. The income tax rate was decreased to 21% by January 2008. The Government of Estonia finalised the design of Estonian euro coins in late 2004, and adopted the euro as the country's currency on 1 January 2011, later than planned due to continued high inflation. A Land Value Tax is levied which is used to fund local municipalities. It is a state level tax, however 100% of the revenue is used to fund Local Councils. The rate is set by the Local Council within the limits of 0.1–2.5%. It is one of the most important sources of funding for municipalities. The Land Value Tax is levied on the value of the land only with improvements and buildings not considered. Very few exemptions are considered on the land value tax and even public institutions are subject to the tax. The tax has contributed to a high rate (~90%) of owner-occupied residences within Estonia, compared to a rate of 67.4% in the United States.
Subway (restaurant)
Advertising affiliates include Subway Franchisee Advertising Fund Trust, Ltd.; Subway Franchisee Advertising Fund Trust, B.V.; Subway Franchisee Canadian Advertising Trust; etc.Subway's international headquarters are in Milford, Connecticut, with five regional centers supporting the company's international operations. The regional offices for European franchises are located in Amsterdam (Netherlands); the Australian and New Zealand locations are supported from Brisbane (Australia); the Asian locations are supported from offices in Beirut (Lebanon) and Singapore; and the Latin American support center is in Miami.
Tobin tax
A Tobin tax was originally defined as a tax on all spot conversions of one currency into another. It was suggested by James Tobin, an economist who won the Nobel Memorial Prize in Economic Sciences. Tobin's tax was originally intended to penalize short-term financial round-trip excursions into another currency. By the late 1990s, however, the term Tobin tax was being incorrectly used to apply to all forms of short term transaction taxation, whether across currencies or not. Another term for these broader tax schemes is Robin Hood tax, due to tax revenues from the (presumably richer) speculator funding general revenue (of whom the primary beneficiaries are less wealthy). More exact terms, however, apply to different scopes of tax.
HD 15115
HD 15115 is a star in the constellation Cetus. Its apparent magnitude is 6.76. Located approximately distant, this F4 subgiant was shown to have an asymmetric debris disk surrounding it. The reason for the asymmetry is thought to be the gravitational pull of a companion star, an exoplanet, or interaction with the local interstellar medium.
Hero Rupes
Hero Rupes is an escarpment on Mercury more than long located in the southern hemisphere of Mercury. Discovered by the "Mariner 10" spacecraft in 1974, it was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time.
Local property tax (Ireland)
The local property tax (LPT) is annual self - assessed tax charged on the market value of all residential properties in Ireland. It came into effect on 1 July 2013 and is collected by the Revenue Commissioners. The tax is assessed on residential properties, with the owner a property being liable (though in the case of leases over twenty years, the tenant becomes liable). The revenue raised is used to fund the provision of services by local authorities and includes transfers between local authorities. Such services currently include public parks; libraries; open spaces and leisure amenities; planning and development; fire and emergency services; maintenance and cleaning of streets; and street lighting. Some recent media reports dispute that such services have been funded from 2013 property tax receipts.
Neptune
Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
American Tax Funding
American Tax Funding (ATF) is a private company based in Jupiter, Florida that engages in the purchasing and servicing of delinquent municipal real estate tax lien sales. Originally formed in 1997 as Transamerica Municipal Finance (TMF), a division of Transamerica Corporation. In August 2000 the founders completed a form of a management buyout of TMF, creating ATF. ATF currently buys and services real estate tax liens in over 14 states and has provided over $1 billion in relief to local governments. Many ATF tax liens are secured by either Wells Fargo Foot Hill or the Harris Nesbitt Corporation. The process of privatizing the municipal tax foreclosures process and outsourcing to out of state third party, for-profit, private companies has drawn criticism from housing advocates who argue that a for-profit tax foreclosure process leads to more foreclosures, displacement and vacancy. The other argument is that third party purchases of tax liens enables local governments to pay for essential services such as salaries for teachers, health care, police officers and firefighters. To date, no study has shown that the sale of tax liens to third parties leads to any increase in foreclosure activity. In fact, the sale of liens to third party purchasers often extends redemption periods and allows flexible repayment agreements for delinquent tax payers.
Renewable energy commercialization
Just as there is a need for tax shifting, there is also a need for subsidy shifting. Subsidies are not an inherently bad thing as many technologies and industries emerged through government subsidy schemes. The Stern Review explains that of 20 key innovations from the past 30 years, only one of the 14 was funded entirely by the private sector and nine were totally publicly funded. In terms of specific examples, the Internet was the result of publicly funded links among computers in government laboratories and research institutes. And the combination of the federal tax deduction and a robust state tax deduction in California helped to create the modern wind power industry.
Weber bar
A Weber bar is a device used in the detection of gravitational waves first devised and constructed by physicist Joseph Weber at the University of Maryland. The device consisted of multiple aluminium cylinders, 2 meters in length and 1 meter in diameter, antennae for detecting gravitational waves.
Touchstone Semiconductor
Touchstone Semiconductor was founded in 2010 by a group of semiconductor industry experts from Maxim Integrated Products, Linear Technology and Analog Devices. The company received $12M funding in Series A funding from Opus Capital and Khosla Ventures, the headquarters were located in Milpitas, California.
Touradji Capital Management
The fund is headquartered at 101 Park Avenue, 48th Floor, New York, NY 10178, USA. Touradji Capital is called a "Tiger Cub", as it is a fund that grew out of Julian Robertson's Tiger Management.
Schiehallion experiment
The Schiehallion experiment was an 18th-century experiment to determine the mean density of the Earth. Funded by a grant from the Royal Society, it was conducted in the summer of 1774 around the Scottish mountain of Schiehallion, Perthshire. The experiment involved measuring the tiny deflection of a pendulum due to the gravitational attraction of a nearby mountain. Schiehallion was considered the ideal location after a search for candidate mountains, thanks to its isolation and almost symmetrical shape. One of the triggers for the experiment were anomalies noted during the survey of the Mason–Dixon line.
Income tax
The US federal government imposed the first personal income tax, on August 5, 1861, to help pay for its war effort in the American Civil War - (3% of all incomes over US $800) (equivalent to $21,800 in 2017). This tax was repealed and replaced by another income tax in 1862. It was only in 1894 that the first peacetime income tax was passed through the Wilson - Gorman tariff. The rate was 2% on income over $4000 (equivalent to $113,000 in 2017), which meant fewer than 10% of households would pay any. The purpose of the income tax was to make up for revenue that would be lost by tariff reductions. The US Supreme Court ruled the income tax unconstitutional, the 10th amendment forbidding any powers not expressed in the US Constitution, and there being no power to impose any other than a direct tax by apportionment.
