Forest Fires.
Types Of Forestfire.
1) Crawling fire: The fire spreads via low level vegetation in the forest. It occurs by the slow combustion of surface fuels. Surface fuels are fuel sources that are on the ground, these can be small bushes, logs, tree stumps and fallen leaves and branches. Crawling or surface fires tend to burn without generating a lot of flame. They can spread slowly and steadily and last for days after the main burning event has occurred.
2) Crown fire: A fire that "crowns" that is, it spreads to the top branches of the trees. It can spread at a remarkable rate through the canopy of a forest. Crown fires burn from aerial fuels, these are fuel sources that are at least 1 meter above the ground. Surface fuels can include branches, leaves, tall bushes and bark still on the tree. Crown fires are the most dangerous type of fire as they can spread faster than they can be outrun, particularly on windy days.
3) Jumping or Spotting fire: In a jumping fire burning branches or leaves are carried by the wind and start distant fires, the fire can jump natural fire breaks like roads and rivers.

Fire Suppression
Fire authorities in areas prone to wild fires often possess helicopters and fixed wing aircraft specially equipped for use in dousing areas that are inaccessible to ground crews, they can deliver large quantities of water or flame retardant chemicals directly onto the fire site.
In the case of fires that are too large to tackle directly, firefighters control the fire by controlling the area to which it can spread. They do this by creating control lines or extended fire breaks. These control lines can be produced by physically removing any fuel source from in front of the fire, or by backfiring. Backfiring involves starting a small, low-intensity fire, to burn off all the flammable material, in the path of the fire. These are then extinguished by firefighters or, directed in such a way that they meet the main fire front, at which point both fires run out of flammable material and are extinguished.
An indication of the skill and dedication employed by professional fire fighting teams can be seen in the fact that in 2004 US firefighters contained more than 99% of all new wildfires during initial suppressive actions.

Lewis W Hine.
In 1907, he became a photographer for the National Child Labor Committee. The NCLC gave Hine his first assigned project, to photograph a New York tenement. Later that year while still at Columbia University graduate school Hine was assigned The Pittsburgh Survey, An ambitious project which aimed to give a detailed view of an industrial city. The survey would describe the gap between the largely unskilled immigrant workers and the affluent managers and executives. The aim of the survey was to highlight and hopefully create an understanding of the social and economic inequalities that were present.
Between 1906 and 1908, Hine worked as a freelance photographer for The Survey, a leading social reform magazine.
In 1908, the NCLC assigned Hine to photograph child labor practices. Hine continued this work until 1917. During this period he travelled widely across America photographing children at work in textile mills, factories, canneries, mines and farming.

In 1917 Hine accepted a position with the American Red Cross were he documented their relief work with refugees and displaced peoples in post war Europe.
In 1920 he returned to New York and was assigned to the American Red Cross National Headquarters. Here he photographed the drought relief work in the American South, for the Tennessee Valley Authority and made photographic studies of life in the mountains of eastern Tennessee.
He also served as chief photographer for the works progress Administration's National Research Project, which was set up to study changes in industry and how this effected employment.
In 1930 Hine was hired to photograph the construction of the Empire State Building. Hine photographed the workers in many precarious positions while they secured the framework of the structure. In order to obtain the best vantage points, Hine was swung out from the building in a specially designed basket.
The series of photographs he produced lead to the 1932 book Men at Work. Critics noted that he had managed to show the human contribution to modern industry while depicting the dignity and power of the American worker. At this time he even exhibited at the 1933 Worlds Fair.
By 1936, Hine was appointed head photographer for the National Research Project of the Works Progress Administration until his death in 1940 after complications from surgery.
The Library of Congress holds more than 5,000 Hine photographs 5,100 photographic prints and 355 glass negatives, given to the Library of Congress, along with the NCLC records, in 1954. NCLC records in the Library of Congress Manuscript Division contain approximately 65 reports, about 30 of which were authored by Hine.

NASA's Deep Impact spacecraft has created a video of the moon transiting the Earth as seen from the spacecraft's point of view 31 million miles away.
Deep Impact was the mission that, on July 4 2005, directed an impactor into comet Tempel 1 so that the internal composition of a comet could be analysed. NASA has now redirected the spacecraft for a flyby of comet Hartley 2 on Nov. 4, 2010.
EPOXI is a combination of the names for the two mission components that NASA has planned for the deep impact craft. The first is a search for extrasolar planets, which will be conducted during the journey to comet Hartley 2, is called Extrasolar Planet Observations and Characterization or EPOCH. The flyby of comet Hartley 2, the second mission, is called the Deep Impact extended Investigation or DIXI.

The Weather Of The Antarctic.
Category 3: Good visibility, clear skies and no wind.
A katabatic wind originates from the cooling of air on a plateau, mountain or glacier. The density of air increases the colder it gets and so air will flow downwards, warming as it descends, thus creating the wind. The temperature of the wind depends on the temperature in the surrounding area and the distance descended.
Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica.The concentration of cold air over the ice sheets and their elevation creates a large amount of gravitational energy. This can propel the winds to hurricane force.
Solar Flares
A solar flare is a an explosion on the surface of the Sun, it occurs when magnetic energy that has built up in the suns atmosphere is suddenly released. Particles are heated and accelerated in the solar atmosphere and radiation is emitted across the entire electromagnetic spectrum from radio waves to gamma rays. The energy released in a flare is ten million times greater than the energy released from a volcanic explosion.
Solar flare up close
Inside a flare, the temperature can be as high as 100 million degrees Kelvin. Solar flares tend to eject solar matter, mostly protons and electrons, into space. These events are called coronal mass ejections.
Solar flares coincides with the Sun's eleven year cycle. When the solar cycle is at a minimum, active regions are small and rare and few solar flares are detected. These increase in number as the Sun approaches the maximum part of its 11 year cycle.

Tilt-shift miniature faking
Tilt-shift miniature faking is a process in which a photograph of a real life location or object is manipulated so as to look like a photograph of a miniature or scale model. To achieve this effect the photographer photoshops the focus of the photograph, to simulate a shallow depth of field, which is more normally associated with a photograph of a miniature model. The area surrounding the central field of focus is blurred, and the colours of the original photograph are heightened.

Tilt-shift photography
Tilt shift encompasses two different types of movements: rotation of the lens, called tilt, and movement of the lens parallel to the image plane, called shift. Tilt is used to control the orientation of the plane of focus to produce an image that appears sharp.while Shift is used to control the perspective.
