 SAINT CASIMIR   (Site not responding. Last check: 2007-11-06)
When Casimir was fifteen, his father placed him in nominal command of an army and sent him to Hungary, where dissension among the Hungarian noblemen led the elder Casimir to believe he could force a Polish ruler on that country.
Casimir had no further part in his country's affairs until he was twenty-one, when he began a four-year rule of Poland while his father was absent on affairs of state in Lithuania.
In 1484, when Casimir himself went to Lithuania on a state visit, a "lung condition" (possibly tuberculosis) that had been troubling him grew worse and was finally the cause of his death on March 4 of that year.

 Casimir effect
The Casimir effect is one of several phenomena that provide convincing evidence for the reality of the quantum vacuum – the equivalent in quantum mechanics of what, in classical physics, would be described as empty space.
Casimir realized that between two plates, only those unseen electromagnetic waves whose wavelengths fit a whole number of times into the gap should be counted when calculating the vacuum energy.
This may be relevant to space travel because the region inside a Casimir cavity has negative energy density.

 The Casimir Force – Neutral or Electrostatic? - ESD Journal
The Casimir force is therefore one of electrostatic attraction, the electrical charge produced by the steady conversion of heat from the thermal surroundings mediated by the electrical grounding of the surfaces.
Upon the evacuation of the gap, the Casimir force loaded the beam, and after a period of time the beam collapsed against the electrode, the contact causing the permanent adhesion of the beam to the electrode.
However, the measurements of Casimir force are made with real materials that are not perfectly reflective, and further have reflectivity that depends on the frequency of the EM radiation in the gap, the latter suggesting the Casimir force may vanish at VUV frequencies as the surfaces contact.

 The Casimir Force
The simplest form of the Casimir effect was predicted in 1948 by H.B.G. Casimir and consists in the attraction between a pair of neutral, parallel conducting plates placed in the vacuum.
Though the Casimir effect is expected to exist for any type of quantum field, in most cases this phenomena is considered for the electromagnetic field in view of the fact that this is the strongest fundamental interaction and it is the most likely to generate measurable effects.
The main feature of the Casimir force is its strong dependence on shape, switching from attractive to repulsive as a function of the geometry and of the coupling with the constraining objects.

One of Casimir's colleagues, Theo Overbeek, realized that the theory that was used at the time to explain van der Waals forces, which had been developed by Fritz London in 1932, did not properly explain the experimental measurements on colloids.
The Casimir force reduced the rate of oscillation and led to nonlinear phenomena, such as hysteresis and bistability in the frequency response of the oscillator.
To prevent the Casimir force from being swamped by the electrostatic force, the mirrors had to be kept neutral by first touching them together before each measurement was made.

 Casimir Effect and Casimir Equation
And so it appears that the Casimir effect is the result of the electron strong charge of the atoms in the metal plates affecting each other through a form of Coulomb's law.
To calculate the force between two Casimir plates, measure the strong charge of each plate (they may not be equal), divide by the distance between them squared, and multiply by the rmfd constant.
According to Gibbs, "The energy density decreases as the plates are moved closer which implies there is a small force drawing them together." That small force is the force of the Aether manifested as the rmfd constant and acting on the strong charge of the electron..

Even in vacuum, the Casimir force between a microscopic sphere and metal paddle alters the frequency of the paddle's oscillation.
A minuscule quantum mechanical attraction between the sphere and plate lowered the frequency of the plate's vibration, and the team varied the frequency by moving the bead.
The Casimir force could cause micromechanical components to stick together, he explains, and so it is important to understand how it interacts with moving parts like the oscillator.

Casimir Pulaski belongs to that select group of heroes, including the Marquis de Lafayefte, Thomas Paine, Giuseppe Garibaldi, and Pulaski's fellow countryman, Thaddeus Kosciuszko, who opposed tyranny not only in their homelands, but wherever they found it.
Under the motto, "For Faith and Freedom," the elder Pulaski assumed the military leadership of the confederation, and Casimir on his 21st birthday took command of a detachment of partisans.
The plot misfired, but it led to the young Casimir being unjustly accused of attempted regicide and later, after he left the country, to a death sentence.
