He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge.

A multiplier ( which is a nonlinear device ) will generate ideally only the sum and difference frequencies, whereas an arbitrary nonlinear block would generate also signals at e. g. 2 · f < sub > 1 </ sub >- 3 · f < sub > 2 </ sub >, etc.

The lower limit of the device size is determined by anti-proton handling issues and fission reaction requirements, but the concept appears to be feasible using technology and infrastructure likely to be made available during the second half of the 21st century, unlike either the Project Orion-type propulsion system, which requires large numbers of nuclear explosive charges, or the various anti-matter drives, which require impossibly expensive amounts of antimatter, antimatter catalyzed nuclear pulse propulsion has technically sweet intrinsic advantages.

* The Quincunx ( ISBN 0-345-37113-5 ) is the title of a lengthy and elaborate novel by Charles Palliser set in 19th-century England, published in 1989 ; the pattern appears in the text as a heraldic device, and is also reflected in the structure of the book.

The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device.

From the perspective of each ensemble member's measuring device, the system appears to have irreversibly collapsed onto a state with a precise value for the measured attributes, relative to that element.

However, if the device is unable to operate through this period of decreased voltage, it will be unable to get enough energy out of the battery, and for all practical purposes, the battery appears " dead " earlier than normal.

NOTE: The Silver Age Phantom Zone appears to be prefigured in the 1950 Superman serial Atom Man vs. Superman, in which Lex Luthor uses a kind of matter-transmitter device to trap Superman in a limbo called the " Empty Doom " from which he can see and hear events in the " real " world but cannot touch anything or be seen or heard.
