Kullen Lighthouse
The Kullen Lighthouse ( sv, Kullens fyr) is an operational lighthouse in Scania, located by the mouth of Öresund, at the point of Kullaberg peninsula, in Höganäs, on the south-west coast of Sweden. Kullen is one of the most prominent landmarks along the Swedish coastline, and with its 1000 Watt electric bulb in a huge lenshouse, also the most powerful lighthouse in Scandinavia, overlooking one of the world's most heavily traveled waters. The lighthouse is 15 meters tall and its focal plane is located 78.5 meters above sea level making it the highest located lighthouse in Sweden. Every 5 seconds, the Kullen Lighthouse flashes white for 0.3 seconds with 27 nautical miles reach. History Kullen is the oldest lighthouse location in Scandinavia founded 1561 by the Danish king Fredrik II This lighthouse was a "Parrot lighthouse" with an iron casket 20 feet above ground. 1563 there was a new stone tower with 12 candlelight as source for light but already 1585 it was replaced wi ...

Kullaberg
Kullaberg () is a peninsula and nature reserve of land protruding into the Kattegat in Höganäs Municipality near the town of Mölle in southwest Sweden. The site in the province of Skåne is an area of considerable biodiversity supporting a number of rare species and has been designated as an Important Bird Area (IBA) in Sweden as well as a Special Protection Area (SPA). The terrain is dominated by steep cliffs rising from the sea and rocky outcrops on the ridge above, the highest elevation being Håkull at 188 metres. Ridgetop vegetation includes a mixed hardwood Temperate broadleaf and mixed forests, broadleaf forest consisting of birch, beech, oak and pine trees with an understory of Crataegus, hawthorn, juniper, wild honeysuckle and blackthorn. Among the notable rare species, rare plants are spring vetchling, ''Lathyrus sphaericus''.

Augustin-Jean Fresnel
Augustin-Jean Fresnel (10 May 1788 – 14 July 1827) was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Newton's corpuscular theory, from the late 1830s until the end of the 19th century. He is perhaps better known for inventing the catadioptric (reflective/refractive) Fresnel lens and for pioneering the use of "stepped" lenses to extend the visibility of lighthouses, saving countless lives at sea. The simpler dioptric (purely refractive) stepped lens, first proposed by Count Buffon and independently reinvented by Fresnel, is used in screen magnifiers and in condenser lenses for overhead projectors. By expressing Huygens's principle of secondary waves and Young's principle of interference in quantitative terms, and supposing that simple colors consist of sinusoidal waves, Fresnel gave the first satisfactory explanation of diffraction by straight edges, inclu ...

Lighthouses Completed In 1900
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mölle
Mölle is a locality situated in Höganäs Municipality, Skåne County, Sweden with 715 inhabitants in 2010. It is best known for its scenic harbour and its location adjacent to the Kullaberg Nature Reserve. Its harbour, situated on the Kattegat Strait, provides services for marine fishing, watersports outings and tour excursions along the coast, especially the rocky shore of Kullaberg to the north. Fodor characterizes Mölle as "a small town set in spectacular isolation on the dramatic headland of the Kulla Peninsula". As a historic seaside resort, Mölle has hosted numerous technical and professional conferences such as: the Swedish Network of European Economists, Joint Swedish-Russian International Workshop on Information Theory; and the Royal Society (United Kingdom) of Tropical Medicine and Hygiene. Logistics Mölle can be accessed from the north south coastal road 111, which effectively accesses Mölle from the south and terminates at Kullaberg, just north of Möl ...

Swedish Maritime Administration
The Swedish Maritime Administration ( sv, Sjöfartsverket) is the government agency in Sweden which provides services to the transport sector by keeping the sea lanes open and safe. The agency is to a certain degree financed through fees levied on commercial shipping. The main services of the Maritime Administration include: pilotage, maintenance of marine fairways, ice-breaking, hydrographics, maritime search and rescue, seamen's service. It also maintains the lighthouses and other aids to navigation of Sweden. Until 1 January 2009, it also was responsible for maritime safety inspection. Seagoing vessels navigating the Baltic Sea must meet certain ice class requirement. While its mainly deals with merchant shipping, other maritime activities are also taken into account. Sjöfartsverket runs the Joint Rescue Center Gothenburg.

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar ( mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely p ...

Metric Ton
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because a ...
