Maze: Solve the World's Most Challenging Puzzle (1985, Henry Holt and Company) is a puzzle book written and illustrated by Christopher Manson. The book was originally published as part of a contest to win $10,000. Unlike other puzzle books, each page is involved in solving the book's riddle.
[1] 6th century BC – Greek philosopher Thales of Miletus observes that rubbing fur on various substances, such as amber, would cause an attraction between the two, which is now known to be caused by static electricity. He noted that rubbing the amber buttons could attract light objects such as hair and that if the amber was rubbed ...
A Bitter electromagnet or Bitter solenoid is a type of electromagnet invented in 1933 by American physicist Francis Bitter used in scientific research to create extremely strong magnetic fields. Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas , as of 2011 [update] .
The first usage of the word electricity is ascribed to Sir Thomas Browne in his 1646 work, Pseudodoxia Epidemica. The first appearance of the term electromagnetism was in Magnes, [35] by the Jesuit luminary Athanasius Kircher, in 1641, which carries the provocative chapter-heading: "Elektro-magnetismos i.e.
Labirinto Della Masone (Mason Labyrinth), built by Franco Maria Ricci (1937–2020) after an idea of his friend the Argentine writer Jorge Luis Borges, was at one time the largest maze in the world. Following Ricci's death, the puzzle of about eight hectares has remained a tourist attraction in the town of Fontanellato near Parma , Italy . [ 1 ]
[2] In 1929, Rolf Wideroe made the next major contribution to the development of the theory by deriving the Wideroe Condition for stable orbits. He determined that in order for the orbit radius to remain constant, the field at the radius must be exactly half of the average field over the area of the magnet.
The 28-acre maze is billed as the world's largest. 'A mountain of corn' in Illinois Though mazes and labyrinths date back thousands of years (think King Minos and the Minotaur in Greek mythology ...
1 T to 2.4 T – coil gap of a typical loudspeaker magnet; 1.5 T to 3 T – strength of medical magnetic resonance imaging systems in practice, experimentally up to 17 T [10] 4 T – strength of the superconducting magnet built around the CMS detector at CERN [11] 5.16 T – the strength of a specially designed room temperature Halbach array [12]
