Linkin Park

Linkin Park is an American rock band from Agoura Hills, California. Formed in 1996, the band rose to international fame with their debut album Hybrid Theory (2000), which was certified diamond by the RIAA in 2005 and multi-platinum in several other countries. Their following studio album Meteora continued the band's success, topping the Billboard 200 album chart in 2003, and was followed by extensive touring and charity work around the world. In 2003, MTV2 named Linkin Park the sixth-greatest band of the music video era and the third-best of the new millennium.Billboard ranked Linkin Park No. 19 on the Best Artists of the Decade chart. In 2012, the band was voted as the greatest artist of the 2000s in a Bracket Madness poll on VH1. In 2014, the band was declared as the Biggest Rock Band in the World Right Now by Kerrang!.

Having adapted nu metal and rap metal to a radio-friendly yet densely layered style in Hybrid Theory and Meteora, the band explored other genres in their next studio album, Minutes to Midnight (2007). The album topped the Billboard charts and had the third-best debut week of any album that year. The band continued to explore a wider variation of musical types in their fourth album, A Thousand Suns (2010), layering their music with more electronic sounds and beats. Their fifth album, Living Things (2012), combines musical elements from all of their previous records. Their sixth and most recent album, The Hunting Party (2014), returned to a heavier rock sound. The band has collaborated with several other artists, most notably with rapper Jay Z in their mashup EP Collision Course, and many others on the remix albums Reanimation and Recharged. Linkin Park has sold over 68 million albums worldwide and has won two Grammy Awards.

Catalysis

Catalysis (/kəˈtælᵻsᵻs/) is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst (/ˈkætəlᵻst/). With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.

Technical perspective

In the presence of a catalyst, less free energy is required to reach the transition state, but the total free energy from reactants to products does not change. A catalyst may participate in multiple chemical transformations. The effect of a catalyst may vary due to the presence of other substances known as inhibitors or poisons (which reduce the catalytic activity) or promoters (which increase the activity). The opposite of a catalyst, a substance that reduces the rate of a reaction, is an inhibitor.

Catalyzed reactions have a lower activation energy (rate-limiting free energy of activation) than the corresponding uncatalyzed reaction, resulting in a higher reaction rate at the same temperature and for the same reactant concentrations. However, the detailed mechanics of catalysis is complex. Catalysts may affect the reaction environment favorably, or bind to the reagents to polarize bonds, e.g. acid catalysts for reactions of carbonyl compounds, or form specific intermediates that are not produced naturally, such as osmate esters in osmium tetroxide-catalyzed dihydroxylation of alkenes, or cause dissociation of reagents to reactive forms, such as chemisorbed hydrogen in catalytic hydrogenation.

Medal of Honor

The Medal of Honor is the United States of America's highest military honor, awarded for personal acts of valor above and beyond the call of duty. The medal is awarded by the President of the United States in the name of the U.S. Congress to U.S. military personnel only. There are three versions of the medal, one for the Army, one for the Navy, and one for the Air Force. Personnel of the Marine Corps and Coast Guard receive the Navy version.

The Medal of Honor was created as a Navy version in 1861 named the "Medal of Valor", and an Army version of the medal named the "Medal of Honor" was established in 1862 to give recognition to men who distinguished themselves "conspicuously by gallantry and intrepidity" in combat with an enemy of the United States. Because the medal is presented "in the name of Congress," it is often referred to as the "Congressional Medal of Honor". However, the official name is the "Medal of Honor," which began with the U.S. Army's version. Within United States Code the medal is referred to as the "Medal of Honor", and less frequently as "Congressional Medal of Honor".

Park

A park is an area of natural, semi-natural, or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. It may consist of grassy areas, rocks, soil, and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. In North America, many parks have fields for playing sports such as soccer, baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses, and these parks may comprise a beach or boat dock area. Often, the smallest parks are in urban areas, where a park may take up only a city block or less. Urban parks often have benches for sitting and they may contain picnic tables and barbecue grills. Parks have differing rules regarding whether dogs can be brought into the park: some parks prohibit dogs; some parks allow them with restrictions (e.g., use of a leash); and some parks, which may be called "dog parks," permit dogs to run off-leash.
