Die Glocke (German: [diː ˈɡlɔkə], 'The Bell') was a purported top-secret scientific technological device, wonder weapon, or Wunderwaffe developed in the 1940s in Nazi Germany. Rumors of this device have persisted for decades after WW2 and were used as a plot trope in the fiction novel Lightning by Dean Koontz (1988).
The 6 m × 4 m × 2.5 m bell is accessible through a 2 m diameter tube and an airlock. A pantograph system keeps the bell and internal stairs level at all depths. Maximum working depth is 10 m. The vessel is used on those inland waterways which have locks large enough to accommodate its 52 m length overall, 11.8 m beam and 1.6 m draft. [30] [31]
Bell expanded on the theorem to provide what would become the conceptual foundation of the Bell test experiments. [ citation needed ] A typical experiment involves the observation of particles, often photons, in an apparatus designed to produce entangled pairs and allow for the measurement of some characteristic of each, such as their spin .
Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden- ...
The Oxford Electric Bell or Clarendon Dry Pile is an experimental electric bell, in particular a type of bell that uses the electrostatic clock principle that was set up in 1840 and which has run nearly continuously ever since. It was one of the first pieces purchased for a collection of apparatus by clergyman and physicist Robert Walker.
[3] [4] [5] Since this style of dagger was usually made en suite with a cup-hilted rapier, the decoration of the knuckleguard tended to reflect that of the cup of the rapier. The edges of the guard are usually turned over toward the outside, possibly to trap the point of the opponent's blade and prevent it from slipping into the defender's hand.
Cannon made of bell metal at Malik-e-Maidan, Bijapur, India. Bell metal or bell bronze is an alloy used for making bells and related instruments, such as cymbals.It is a form of bronze with a higher tin content than most other bronzes, usually in approximately a 4:1 ratio of copper to tin (typically, 78% copper, 22% tin by mass).
In law, unring the bell is an analogy used to suggest the difficulty of forgetting information once it is known. When discussing jury trials , the phrase is sometimes used to describe the judge's instructions to the jury to ignore inadmissible evidence or statements they have heard.
