A NHDP projects up to phase IIIB, which is due to be completed by December 2012. The National Highways are the main long-distance roadways and constitute a total of about 58,000 km (36,250 mi), of which 4,885 km (3,053 mi) are central-separated expressways . Highways in India are around 2% of the total road network in India, but carry nearly 40% of the total road traffic.

A male lion (Panthera leo) lying down in Namibia. One of the four "big cats" in the genus Panthera, the lion is the second largest cat, after the tiger. Males weigh between 150-250 kg (330-550 lb), and are easily recognizable by their manes. Though they were once found throughout much of Africa, Asia and Europe, lions presently exist in the wild only in Africa and India. Photo credit: yaaaay

A burning match, a consumable artifact for producing fire under controlled circumstances on demand. A match is typically a wooden stick (usually sold in boxes) or stiff paper stick (usually sold in matchbooks) coated at one end with a material, the match head, often containing the element phosphorus, that will ignite from the heat of friction if struck against a suitable surface.

On October 22, 1895, the Granville–Paris Express train overran the buffer stop at Gare Montparnasse station. The engine careened across almost 30 metres (100 feet) of the station concourse, crashed through a 60 centimetre thick wall, shot across a terrace and sailed out of the station, plummeting onto the Place de Rennes 10 metres (30 feet) below where it stood on its nose. While all of the passengers on board the train survived, one woman on the street below was killed by falling masonry. Photo credit: Studio Lévy and Sons

wind-swept sand with little to no vegetation cover. Approximately 85% of all the Earth's mobile sand is found in ergs that are larger than 32,000 km². Individual dunes in ergs typically have widths, lengths, or both dimensions greater than 500 m.
Ergs can be found where an atmosphere capable of significant wind erosion acts on the surface for a significant period of time, creating sand and allowing it to accumulate. Today at least three bodies, apart from Earth, are known in the solar system to feature ergs on their surface: Venus, Mars and Titan. Photo credit: Rosa Cabecinhas and Alcino Cunha

A whole and a cut lemon. Lemons are used primarily for their juice, though the pulp and rind (zest) are also used, primarily in cooking or mixing. Lemon juice is about 5% citric acid, which gives lemons a sour taste and a pH of 2 to 3. This acidity makes lemon juice a cheap, readily available acid for use in educational chemistry experiments.

The first of a magnification series of a snow crystal (view the entire series) using a low temperature scanning electron microscope with magnification up to 100,000X, compared to 30X – 500X available with light microscopes. Snow samples are very fragile and exposure to the light necessary to photograph them, using light microscopes, can damage the crystals and even melt them. A low temperature SEM operating at −170°C avoids disturbing the structure. Photo credit: Agricultural Research Service
