Brest, France
Brest (; ) is a port city in the Finistère department, Brittany. Located in a sheltered bay not far from the western tip of the peninsula, and the western extremity of metropolitan France, Brest is an important harbour and the second French military port after Toulon. The city is located on the western edge of continental France. With 142,722 inhabitants in a 2007 census, Brest forms Western Brittany's largest metropolitan area (with a population of 300,300 in total), ranking third behind only Nantes and Rennes in the whole of historic Brittany, and the 19th most populous city in France; moreover, Brest provides services to the one million inhabitants of Western Brittany. Although Brest is by far the largest city in Finistère, the ''préfecture'' (regional capital) of the department is the much smaller Quimper. During the Middle Ages, the history of Brest was the history of its castle. Then Richelieu made it a military harbour in 1631. Brest grew around its arsenal unti ...

Optical Physicists
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be acc ...

Diego Garcia
Diego Garcia is an island of the British Indian Ocean Territory, a disputed overseas territory of the United Kingdom. It is a militarised atoll just south of the equator in the central Indian Ocean, and the largest of the 60 small islands of the Chagos Archipelago.

Malabar Coast
The Malabar Coast is the southwestern coast of the Indian subcontinent. Geographically, it comprises the wettest regions of southern India, as the Western Ghats intercept the moisture-laden monsoon rains, especially on their westward-facing mountain slopes. The term is used to refer to the entire Indian coast from the western coast of Konkan to the tip of India at Kanyakumari. The peak of Anamudi, which is also the point of highest altitude in India outside the Himalayas, and Kuttanad, which is the point of least elevation in India, lie on the Malabar Coast. Kuttanad, also known as ''The Rice Bowl of Kerala'', has the lowest altitude in India, and is also one of the few places in the world where cultivation takes place below sea level. The region parallel to the Malabar Coast gently slopes from the eastern highland of Western Ghats ranges to the western coastal lowland. The moisture-laden winds of the Southwest monsoon, on reaching the southernmost point of the Indian Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mahé, Seychelles
Mahé is the largest island of Seychelles, with an area of , lying in the northeast of the Seychellean nation in the Somali Sea part of the Indian Ocean.
