In physics, mass (from Greek μᾶζα "barley cake, lump (of dough)"), more specifically inertial mass, can be defined as a quantitative measure of an object's resistance to the change of its speed. In addition to this, gravitational mass can be described as a measure of magnitude of the gravitational force which is
when interacting with a second object. The SI unit of mass is the kilogram (kg).
In everyday usage, mass is often referred to as weight, the units of which are often taken to be kilograms (for instance, a person may state that their weight is 75 kg). In scientific use, however, the term weight refers to a different, yet related, property of matter. Weight is the gravitational force acting on a given body—which differs depending on the gravitational pull of the opposing body (e.g. a person's weight on Earth vs on the Moon) — while mass is an intrinsic property of that body that never changes. In other words, an object's weight depends on its environment, while its mass does not. On the surface of the Earth, an object with a mass of 50 kilograms weighs 491 Newtons; on the surface of the Moon, the same object still has a mass of 50 kilograms but weighs only 81.5 Newtons. Restated in mathematical terms, on the surface of the Earth, the weight W of an object is related to its mass m by W = mg, where g is the Earth's gravitational field strength, equal to about 9.81 m/s2.
Arnold Alois Schwarzenegger ( /ˈʃwɔrtsənɛɡər/; German: [ˈaɐnɔlt ˈalɔʏs ˈʃvaɐtsənˌʔɛɡɐ]; born July 30, 1947) is an Austrian and American former professional bodybuilder, actor, businessman, investor, and politician. Schwarzenegger served as the 38th Governor of California from 2003 until 2011.
Schwarzenegger began to weight train at the age of 15 years old. He was awarded the title of Mr. Universe at age 20 and went on to win the Mr. Olympia contest seven times. Schwarzenegger has remained a prominent presence in the sport of bodybuilding and he has written several books and numerous articles on the sport. Schwarzenegger gained worldwide fame as a Hollywood action film icon. He was nicknamed the "Austrian Oak" and the "Styrian Oak" in his bodybuilding days, "Arnie" during his acting career and more recently the "Governator" (from "Governor" and "Terminator").
As a Republican, he was first elected on October 7, 2003, in a special recall election to replace then-Governor Gray Davis. Schwarzenegger was sworn in on November 17, 2003, to serve the remainder of Davis's term. Schwarzenegger was then re-elected on November 7, 2006, in California's 2006 gubernatorial election, to serve a full term as governor, defeating Democrat Phil Angelides, who was California State Treasurer at the time. Schwarzenegger was sworn in for his second term on January 5, 2007.
Our life sewn, from total darkness.
Harvesting doubt, preserve the abscess.
An emotional bout, a total state of unrest.
Thrive on despair, to prey on a weakness.
Lyers, sewn by lyers.
