Mass

In physics, mass is a property of a physical body. It is generally a measure of an object's resistance to changing its state of motion when a force is applied. It is determined by the strength of its mutual gravitational attraction to other bodies, its resistance to being accelerated by a force, and in the theory of relativity gives the mass–energy content of a system. The SI unit of mass is the kilogram (kg).

Mass is not the same as weight, even though we often calculate an object's mass by measuring its weight with a spring scale instead of comparing it to known masses. An object on the Moon would weigh less than it would on Earth because of the lower gravity, but it would still have the same mass.

For everyday objects and energies well-described by Newtonian physics, mass describes the amount of matter in an object. However, at very high speeds or for subatomic particles, special relativity shows that energy is an additional source of mass. Thus, any stationary body having mass has an equivalent amount of energy, and all forms of energy resist acceleration by a force and have gravitational attraction.

America (advertisement)

"America" is an American political advertisement released by the 2016 presidential campaign of Bernie Sanders. It premiered on January 21, 2016 via YouTube, and to air on television in Iowa and New Hampshire shortly before the Democratic Iowa caucus and New Hampshire primary.

The advertisement features "America," a song recorded by Simon & Garfunkel for their album Bookends (1968).

The ad starts with scenes of everyday American life over soft humming and gentle guitar strumming. As the line, "let us be lovers, we'll marry our fortunes together" plays in the background, a middle-aged couple dances at a small Bernie Sanders for President rally. Then Sanders is seen speaking to a few people in a backyard. As the ad continues, the crowds grow larger and more enthusiastic. A montage of many Sanders supporters appear, as the words "They've all come to look for America" flash on the screen. Sanders is then seen addressing a large outdoor gathering, interacting one-on-one with supporters, appearing before more energetic crowds, finally ending in a large auditorium filled to capacity with cheering people.

Virginia Tech

Virginia Polytechnic Institute and State University, popularly known as Virginia Tech, is a public, land-grant, research university with a main campus in Blacksburg, Virginia, educational facilities in six regions statewide, and a study-abroad site in Switzerland. The commonwealth's third-largest university and its leading research institution, Virginia Tech offers 225 undergraduate and graduate degree programs to some 29,373 students and manages a research portfolio of US$513 million. The university fulfills its land-grant mission of transforming knowledge to practice through technological leadership and by fueling economic growth and job creation locally, regionally, and across Virginia.

The Virginia Tech Board of Visitors, which serves as the university's governing body, comprises 13 members who are appointed by the governor of Virginia; the president of the state's Board of Agriculture and Consumer Services serves ex-officio as the 14th voting member. Serving as non-voting representatives are the presidents of the university's Faculty Senate and Staff Senate, who serve ex-officio, and an undergraduate student and a graduate student selected through a competitive review process. The endowment is managed by the Virginia Tech Foundation, and as of 2015 topped US$817.8 million.

The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.

The Catholic University of America (CUA) is a private university located in Washington, D.C. in the United States. It is a pontifical university of the Catholic Church in the United States and the only institution of higher education founded by the U.S. Catholic bishops. Established in 1887 as a graduate and research center following approval by Pope Leo XIII on Easter Sunday, the university began offering undergraduate education in 1904. The university's campus lies within the Brookland neighborhood, known as "Little Rome", which contains 60 Catholic institutions, including Trinity Washington University and the Dominican House of Studies.

It has been ranked as one of the nation's best colleges by the Princeton Review, one of the best values of any private school in the country by Kiplinger's, "one of the most eco-friendly universities in the country," and was awarded the "highest federal recognition an institution can receive" for community service. In addition, it was ranked in the top 10 of the best Catholic colleges in the country, and has been recommended by the Cardinal Newman Society in The Newman Guide to Choosing a Catholic College. It was described as one of the 25 most underrated colleges in the United States.
