Title: Breaking (martial arts)
Content: Wood, which is a natural fibrous matrix, flexes to a certain degree before it snaps at the target point. When unpegged, this allows for an entire stack of wood to flex upon impact, resulting in the break occurring in the order of furthest board from impact to the closest board (albeit a fraction of a second difference separates each board, making it appear instantaneous). This can be witnessed in many novice demonstrations where the rear board will break, but the remaining top boards are intact. When pegged, the gap between the boards necessitates each individual board to flex and snap

Title: Cracking (chemistry)
Content: Cracking (chemistry) In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. This process might require high temperatures and high pressure. More loosely,

Title: John McGeehan
Content: group in 2016. The team at Portsmouth University, together with researchers at the U.S. Department of Energy's National Renewable Energy Laboratory and the University of South Florida, solved the high-resolution structure of the PETase enzyme using X-ray crystallography at the Diamond Light Source. The team used the structure to design an improved version of the enzyme, making it more efficient, and raising the possibility of further efficiency gains. They demonstrated that it can also break down polyethylenefuranoate (PEF), a potential plant-based PET replacement. Plastics such as PET, while incredibly versatile, are resistant to natural breakdown and are now an increasing

Title: Breaking (martial arts)
Content: of mental fortitude, the ability of the mind and body to overcome. Generally, a martial artist engaged in breaking will practice by repeatedly hitting hard surfaces. Masutatsu Oyama, a famous breaker who was known for breaking the horns off bulls, would use trees. In karate, a device called a makiwara is used; this device has found more popular use by practitioners of other martial arts today. In the past, Shaolin and other earlier martial artists would use many different types of devices in order to condition themselves, not always for simply breaking, but using the same concepts used today. For

Title: Break Down (Landy artwork)
Content: an industrial assembly line, with items circulating in yellow trays on long figure-of-eight conveyor belt. Ten workers systematically removed each item from the convey belt and reduced it to its basic materials by smashing, shredding and pulverising them. The work attracted around 45,000 visitors. The resulting bags of granulated rubbish weighed nearly 6 tonnes, and were recycled or sent to landfill. None was exhibited or sold. Landy's full inventory was published as a 300-page volume, "Break Down Inventory" in 2002. Following the exhibition, Landy was left with no possessions. He did not return to art for a year. In a
