Fire

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

Fire is hot because conversion of the weak double bond in molecular oxygen, O₂, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O₂); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.

Eden Project

The Eden Project (Cornish: Edenva) is a visitor attraction in Cornwall, England, United Kingdom. Inside the two biomes are plants that are collected from many diverse climates and environments. The project is located in a reclaimed Kaolinite pit, located 2 km (1.2 mi) from the town of St Blazey and 5 kilometres (3 mi) from the larger town of St Austell, Cornwall.

The complex is dominated by two huge enclosures consisting of adjoining domes that house thousands of plant species, and each enclosure emulates a natural biome. The biomes consist of hundreds of hexagonal and pentagonal, inflated, plastic cells supported by steel frames. The largest of the two biomes simulates a Rainforest environment and the second, a Mediterranean environment. The attraction also has an outside botanical garden which is home to many plants and wildlife native to Cornwall and the UK in general; it also has many plants that provide an important and interesting backstory, for example, those with a prehistoric heritage.

Five Nights

Five Nights is a 1915 British silent romance film directed by Bert Haldane and starring Eve Balfour, Thomas H. MacDonald and Sybil de Bray. It was based on a novel of the same title by Victoria Cross.

The Roots

The Roots are an American hip hop/neo soul band, formed in 1987 by Tariq "Black Thought" Trotter and Ahmir "Questlove" Thompson in Philadelphia, Pennsylvania, United States. The Roots are known for a jazzy and eclectic approach to hip-hop featuring live musical instruments.Malik B., Leonard "Hub" Hubbard, and Josh Abrams were added to the band (formerly named "The Square Roots").

Since its first independent album-length release the band has released 10 studio albums, two EPs, two collaboration albums (with other artists), and also collaborated on recordings and in live shows with a wide variety of artists in many musical genres. The Roots served as the house band on NBC's Late Night with Jimmy Fallon from 2009 to 2014, and in the same role (and accompanying show guest artists) on The Tonight Show Starring Jimmy Fallon since 2014. The Roots' work has consistently been met with critical acclaim. About.com ranked the band #7 on its list of the 25 Best Hip-Hop Groups of All-Time, calling them "Hip-hop's first legitimate band."
