The newton (symbol: N) is the SI derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.

The newton is the SI unit for force; it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one metre per second squared. Newton's second law of motion states: F = ma, multiplying m (kg) by a (m/s²), The newton is therefore:

Kilonewtons are often used for stating safety holding values of fasteners, anchors, and more in the building industry. They are also often used in the specifications for rock climbing equipment. The safe working loads in both tension and shear measurements can be stated in kilonewtons. Injection moulding machines, used to manufacture plastic parts, are classed by kilonewton (i.e., the amount of clamping force they apply to the mould).

On the Earth's surface, 1 kN is about 101.97162 kilogram-force of load, but multiplying the kilonewton value by 100 (i.e. using a slightly conservative and easier to calculate value) is a good rule of thumb.

Tony Rice (born David Anthony Rice, June 8, 1951, Danville, Virginia) is an American acoustic guitarist and bluegrass musician. He is considered one of the most influential acoustic guitar players in bluegrass, progressive bluegrass, newgrass and acoustic jazz.

Rice spans the range of acoustic music, from traditional bluegrass to jazz-influenced New Acoustic music, to songwriter-oriented folk. Over the course of his career, he has played alongside J. D. Crowe and the New South, David Grisman (during the formation of “Dawg Music”) and Jerry Garcia, led his own Tony Rice Unit, collaborated with Norman Blake, recorded with his brothers Wyatt, Ron and Larry and co-founded the Bluegrass Album Band. He has recorded with drums, piano, soprano sax, as well as with traditional bluegrass instrumentation.

Rice was born in Danville, Virginia but grew up in Los Angeles, California, where he was introduced to bluegrass by his father, a semi-professional musician named Herb Rice. Tony and his brothers learned the fundamentals of bluegrass and country music from hot L.A. pickers like the Kentucky Colonels, led by Roland and Clarence White. Clarence White in particular became a huge influence on Tony Rice. Crossing paths with fellow enthusiasts like Ry Cooder, Herb Pedersen and Chris Hillman reinforced the strength of the music he had learned from his father.

Norvell William "Bill" Emerson (January 1, 1938 – June 22, 1996) was an American politician from Missouri. He served in the United States House of Representatives from 1981 until his death in 1996. He was succeeded in the House by his widow, Jo Ann Emerson. Emerson was a Republican.

Emerson was raised in Jefferson County, Missouri and attended public schools in nearby Hillsboro. He served as a House Page and graduated from Westminster College in Fulton, Missouri in 1959. Emerson attended law school at the University of Missouri and the University of Baltimore, graduating with his LL.B from Baltimore in 1964. He was also a Captain in the United States Air Force Reserve from 1964 to 1992.

He was serving as a congressional page serving on the floor during the 1954 United States Capitol shooting incident involving Puerto Rico terrorists. While in law school, Emerson served as a Congressional aide to U.S. Representative Robert Ellsworth, and after graduation he served on the staff of U.S. Senator Charles Mathias. Throughout the 1970s he worked in governmental affairs for several companies, and formed his own consulting group in 1979. In 1980, he was elected to Congress and was re-elected seven times. Emerson served on the House Committee on Rules.
