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.

The National Natural Landmarks in Alaska include 16 of the almost 600 National Natural Landmarks (NNLs) in the United States. They cover areas of geological and biological importance, and include craters, volcanoes, glaciers, lakes, islands and habitats for several rare species.
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.
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 ...
Kiska Island is now protected as part of the Alaska Maritime National Wildlife Refuge, and authorization is required to visit the island. The central portion of the island, where the Japanese facilities were concentrated, and where the Allied landing took place, was designated a National Historic Landmark and listed on the National Register of ...
