This is a list of the world's largest machines, both static and movable in history. Building structure. Large Hadron Collider – The world's largest single machine;
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts ).
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
This is a list of islands of the U.S. state of Alaska. Approximately 2,670 named islands help to make Alaska the largest state in the United States . [A] [ 1 ]
The English name for the island comes from Pitka Pavalof, a Creole of Russian-Native. In 1893, Pitka Pavalof and Sergei Gologoff Cherosky, Creoles of Russian-Native descent, found gold on Birch Creek in Interior Alaska. Learning of the discovery, prospectors jumped their claims and argued that the claims were invalid because the men were Natives.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
According to Donald Orth's Dictionary of Alaska Place Names (p. 64), the Alexander Archipelago received its name from the U.S. Coast and Geodetic Survey in 1867. The island chain is named for Tsar Alexander II of Russia. [6] On an 1860 map of Russian America (Alaska), the island group is called the King George III Archipelago.
Shishaldin is located on Unimak Island, the easternmost of the Aleutian Islands. The nearest settlement to the volcano is False Pass (population ~100) at 45 km away. The view of Shishaldin from False Pass is obscured by the Round Top and Isanotski volcanoes, [2] preventing direct observations of eruptions in many instances. [7]
