Géant Glacier
The Géant Glacier (french: Glacier du Géant) is a large glacier on the French side of the Mont Blanc massif in the Alps. It is the main supplier of ice (via the Vallée Blanche) to the Mer de Glace which flows down towards Montenvers. It gets its name from the nearby Dent du Géant. Access It is possible to take the Vallée Blanche Cable Car which travels right over the Géant Glacier, from the Aiguille du Midi in France, to Pointe Helbronner on the Italian/French border. Experienced skiers also have an "outstanding attraction" in the challenging run from the Aiguille du Midi telepherique station, down the Vallée Blanche and onto the Géant Glacier then, avoiding the Seracs du Géant, merging onto the Mer du Glace to reach the resort of Montenvers Early studies In 1862, the physicist and mountaineer John Tyndall gave a series of lectures to the Royal Institution The Royal Institution of Great Britain (often the Royal Institution, Ri or RI) is an organisation for sc ...

Mont Blanc
Mont Blanc (french: Mont Blanc ; it, Monte Bianco , both meaning "white mountain") is the highest mountain in the Alps and Western Europe, rising above sea level. It is the second-most prominent mountain in Europe, after Mount Elbrus, and it is the eleventh most prominent mountain summit in the world. It gives its name to the Mont Blanc massif which straddles parts of France, Italy and Switzerland. Mont Blanc's summit lies on the watershed line between the valleys of Ferret and Veny in Italy, and the valleys of Montjoie, and Arve in France. Ownership of the summit area has long been a subject of dispute between France and Italy. The Mont Blanc massif is popular for outdoor activities like hiking, climbing, trail running and winter sports like skiing, and snowboarding. The most popular climbing route to the summit of Mont Blanc is the Goûter Route, which typically takes two days. The three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dent Du Géant
The Dent du Géant ( It.: Dente del Gigante, "giant's tooth") (4,013 m) is a mountain in the Mont Blanc massif in France and Italy. The Dent du Géant remained unclimbed during the golden age of alpinism, and was a much-coveted peak in the 1870s, repelling many parties who attempted it mostly from the Rochefort ridge. In 1880 the strong team of Albert F. Mummery and Alexander Burgener tried to force a passage via the south-west face but were repelled by a band of slabs, causing Mummery to exclaim, 'Absolutely inaccessible by fair means!' The mountain has two summits, apart and separated by a small col (an 'extremely awkward notch' according to W. W. Graham): :*''Pointe Sella'' (4,009 m), first ascent via the south-west face by Jean Joseph Maquignaz with son Baptiste Maquignaz and nephew, Daniel Maquignaz on 28 July 1882.

Tyndall 1896 Figure 7-37-MJ2
Tyndall (the original spelling, also Tyndale, "Tindol", Tyndal, Tindoll, Tindall, Tindal, Tindale, Tindle, Tindell, Tindill, and Tindel) is the name of an English family taken from the land they held as tenants in chief of the Kings of England and Scotland in the 11th, 12th and 13th centuries: Tynedale, or the valley of the Tyne, in Northumberland. With origins in the ancient Anglo Saxon nobility of Northumbria, the Royal Scottish House of Dunkeld and the Anglo-Norman nobility, they have contributed courtiers, judges, writers, historians, sailors, airmen, scientists and philosophers to the history of England, Ireland and the new world. Two members of the family were offered, and declined, the throne of Bohemia in the 15th century and one of their number, William Tyndale, was the first modern translator of the Bible into English and one of the most important figures in the evolution of the modern language. The family is spread today throughout the British Isles and the Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Institution Of London
The Royal Institution of Great Britain (often the Royal Institution, Ri or RI) is an organisation for scientific education and research, based in the City of Westminster. It was founded in 1799 by the leading British scientists of the age, including Henry Cavendish and its first president, George Finch. Its foundational principles were diffusing the knowledge of, and facilitating the general introduction of useful mechanical inventions and improvements, as well as enhancing the application of science to the common purposes of life (including through teaching, courses of philosophical lectures, and experiments). Much of the Institution's initial funding and the initial proposal for its founding were given by the Society for Bettering the Conditions and Improving the Comforts of the Poor, under the guidance of philanthropist Sir Thomas Bernard and American-born British scientist Sir Benjamin Thompson, Count Rumford. Since its founding it has been based at 21 Albemarle Street i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Tyndall
John Tyndall Fellow of the Royal Society, FRS (; 2 August 1820 – 4 December 1893) was a prominent 19th-century Irish physicist. His scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric Carbon dioxide, CO and what is now known as the greenhouse effect in 1859. Tyndall also published more than a dozen science books which brought state-of-the-art 19th century experimental physics to a wide audience. From 1853 to 1887 he was professor of physics at the Royal Institution of Great Britain in London. He was elected as a member to the American Philosophical Society in 1868. Early years and education Tyndall was born in Leighlinbridge, County Carlow, Ireland. His father was a local police constable, descended from Gloucestershire emigrants who settled in southeast Ireland around 1670. Tyndall attended the local schools (Ballinabra ...

Pointe Helbronner
Pointe Helbronner () is a mountain in the Mont Blanc massif in the Graian Alps on the watershed between France and Italy. The peak, which used to be a mere geodetic reference point, was named after Paul Helbronner, a French '' polytechnicien'', alpinist and geodesist who pioneered cartography of the French Alps. Pointe Helbronner is served on the Italian side by the Skyway Monte Bianco, a cable car from La Palud, a village north of the town of Courmayeur in the Aosta Valley. Pointe Helbronner is also served by the Vallee Blanche Aerial Tramway, which crosses from the peak to the nearby peak of Aiguille du Midi in France—a peak-to-peak distance of . This, in turn, gives access to the French Téléphérique de l'Aiguille du Midi, the cable car connecting Aiguille du Midi to the French village of Chamonix, Courmayeur's sister "city". The Skyway Monte Bianco station platform on Pointe Helbronner offers a remarkable view over the Aosta Valley and the Piedmont region. ...

Aiguille Du Midi
The Aiguille du Midi () is a mountain in the Mont Blanc massif within the French Alps. It is a popular tourist destination and can be directly accessed by cable car from Chamonix that takes visitors close to Mont Blanc. Cable car The idea for a cable car to the summit, the ''Téléphérique de l'Aiguille du Midi'', was originally proposed around 1909, but did not come into operation until 1955 when it held the title of the world's highest cable car for about two decades. It still holds the record as the highest vertical ascent cable car in the world, from . There are two sections: from Chamonix to ''Plan de l'Aiguille'' at and then directly, without any support pillar, to the upper station at 3,777 m (the building contains an elevator to the summit). The span of the second section is measured directly, but only measured horizontally. Thus it remains the second longest span width, measured directly. The cable car travels from Chamonix to the top of the Aiguille du Midi – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallée Blanche Cable Car
The Vallée Blanche Cable Car ( it, Funivia dei Ghiacciai) (french: Télécabine Panoramic Mont-Blanc), (previously ), is a passenger cable car linking a mountain peak above Courmayeur (Italy) to a peak above Chamonix (France) by passing over the Mont Blanc massif, in the Alps. The engineering was developed by Vittorio Zignoli of Polytechnic University of Turin. No helicopters were used, and all the workers were chosen among locals and alpine guides. After a construction period of four years, it began service in 1958. The cable car connects the peaks of ''Aiguille du Midi'' ( elevation) and ''Pointe Helbronner'' ( elevation), over a distance of some . This tourist attraction spans the valleys between the two peaks, high above the Mont Blanc Tunnel, which carries automotive passenger and freight traffic under the two peaks. System The Vallée Blanche Cable Car has fixed track cables (one each direction) carrying 12 groups of 3 small cabins each which are pulled by a haulage rope ...

Tour Ronde
The Tour Ronde () is a mountain in the Mont Blanc massif of the Alps, situated on the border between France and Italy. It is a prominent mountain, some 3.5 km north-east of Mont Blanc, but is effectively part of a continuation of the south eastern spur of Mont Maudit (l'Arete de la Brenva) which forms a frontier ridge between the two countries. It is easily accessible to mountaineers and provides not only a very good viewpoint from its summit of the Brenva face and the major peaks on the southern side of Mont Blanc, but it also offers a popular introduction to alpine climbing of all grades, including a north face ascent. First Ascents * First ascent by J.Backhouse, T. Carson, Douglas Freshfield and C. Tucker with Daniel Balleys and Michel Payot, 22 July 1867. * First ascent of the North face was by F. Gonella and A. Berthod on 23 August 1886. * First winter ascent: U. Mautino with J. Petigax and C. Croux, c.1895 Viewpoint The relatively isolated but easily accessible s ...

Mer De Glace
The Mer de Glace ("Sea of Ice") is a valley glacier located on the northern slopes of the Mont Blanc massif, in the French Alps. It is 7.5 km long and deep but, when all its tributary glaciers are taken into account, it can be regarded as the longest and largest glacier in France, and the second longest in the Alps after the Aletsch Glacier. Geography The glacier lies above the Chamonix valley. The pressure within the ice is known to reach at least 30 atmospheres. The Mer de Glace can be considered as originating at an elevation of , just north of the Aiguille du Tacul, where it is formed by the confluence of the Glacier de Leschaux and the Glacier du Tacul. The former is fed by the Glacier du Talefre, whilst the latter is, in turn, fed by the Glacier des Periardes, the vast Glacier du Géant and the broad icefields of the Vallee Blanche. The Glacier du Tacul supplies much more ice than the Glacier de Leschaux. However, if the Mer de Glace is considered in its broadest ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
