Robert Novak - Encyclopedia Glossary Meaning Explanation Robert Novak.
Robert David Novak (born February 26, 1931) is a U.S. conservative columnist ("Inside Report", since 1963; until 1993 co-written with Rowland Evans) who is also well known as a television personality.
Many observers complained that Novak was inconsistent as he refused to reveal the source of the Plame leak, although he later called on CBS to reveal the source of the memos alleging President Bush had evaded National Guard service (see Rathergate).

 Independent, The (London): Obituary: Professor David Shoenberg   (Site not responding. Last check: 2007-10-09)
Although superconductivity had been discovered in 1911, until 1933 it was seen only as a sudden and mysterious disappearance of electrical resistance when certain metals were cooled to within a few degrees of absolute zero.
But in 1933 Walther Meissner and Robert Ochsenfeld found the even stranger property that no magnetic field could remain inside a superconductor; so Shoenberg in 1935 was entering a virtually new area of physics.
His most important work here used minute spherules of mercury made by the old pharmacist's trick of grinding the liquid metal with chalk; he could then measure the thickness of the layer, only a few hundred atoms, which was as far as a magnetic field could penetrate.

The Meissner effect is the total exclusion of any magnetic flux from the interior of a superconductor.
It was discovered by Walter Meissner and Robert Ochsenfeld in 1933 and it is often referred to as perfect diamagnetism or the Meissner-Ochsenfeld effect.
The Meissner effect is one of the defining features of superconductivity, and its discovery served to establish that the onset of superconductivity is a phase transition.

 Case Study 3 presntation | The history of superconductors
In 1933, Walther Meissner and Robert Ochsenfeld discovered that superconducting materials expel magnetic fields from within themselves.
In 1950, Fritz London predicted that magnetic flux is quantised (this is an important principle of SQUIDS), and the Ginzburg-Landau theory successfully predicted the electrical behaviour of superconductors, using quantum mechanics.
In 1957 John Bardeen, Leon Cooper and Robert Schrieffer took everything that was currently known about superconductors, and put it into one theory.

1933 Walter Meissner and Robert Ochsenfeld discovered that a superconducting material will repel a magnetic field.
He and R. Ochsenfeld discovered the Meissner effect in 1933.
The definition of the Meissner effect is as follows: The falling off of a magnetic flux within a superconducting metal when it is cooled to a temperature below the critical temperature in a magnetic field.

Settling temporarily in Oxford, they collaborated in formulating a theory of superconductivity designed to explain the surprising result, reported in 1933 by Walther Meissner and Robert Ochsenfeld, that superconductors expel magnetic fields.
The vanishing of the resistance observed by Meissner and Ochsenfeld followed from the second equation.
What the Londons realized, and expressed in their second equation, is that what is proportional to the electric field in a superconductor is not the current, as in the normal case, but the change in the current with time.

 The Meissner-Ochsenfeld effect   (Site not responding. Last check: 2007-10-09)
If this permanent magnet had a magnetic field strong enough to support its own weight, it could be levitated above the perfect conductor.
In Berlin in 1933, an experiment was done by Walther Meißner and Robert Ochsenfeld to test whether superconductors behaved the way Maxwell's laws predicted a perfect conductor to behave.
They found that a superconductor will expel any magnetic flux whether it becomes superconducting before or after the magnetic field is brought near it.

No magnetic field opposite the magnetic field of the permanent magnet would be present, and it would not be possible to levitate the magnet.
This phenomenon is now known as the Meißner- Ochsenfeld effect, more commonly referred to as the Meissner effect.
The BCS Theory, however, developed in 1957 by John Bardeen, Leon Cooper, and Robert Schrieffer, does establish a model for the mechanism behind superconductivity.

In 1933, Walter Meissner and Robert Ochsenfeld found that a superconducting material was able to repel a magnetic field.
What Meissner and Ochsenfeld discovered is that a superconducting material will repulse the magnetic field that would normally penetrate the conductor.
This is known as dimagnetism and is commonly called the Meissner effect.

The German physicists Walther Meissner and Robert Ochsenfeld discovered another exciting property of superconductors in 1933.
They found that when a superconducting material is cooled below its critical temperature in the presence of an applied magnetic field, it expels all magnetic flux from its interior.

The slow and sometimes very intermittent progress of research during the last century, nevertheless, brought a number of advances in the fundamental knowledge of the superconductor phenomenon and its unique properties.
It was in 1933 that the Germans Walter Meissner and Robert Ochsenfeld demonstrated the surprising diamagnetic effect (now known as the Meissner effect) by which a current passing through a superconductor exercises a strong repelling force on an external magnetic field.
This property causes a magnet brought close to a material in a superconductive state to levitate spectacularly.

Another fundamental property of the superconducting state was discovered in 1933 when Walther Meissner and Robert Ochsenfeld demonstrated that superconductors expel any residual magnetic field.
So the recent discovery of compounds that are both ferromagnetic and superconducting at the same time came as a surprise to many physicists.
The microscopic theory of superconductivity was created by John Bardeen, Leon Cooper and Robert Schrieffer in 1957.

He also discovered that this dissipation-free state of matter, named superconductivity, was destroyed by high currents and external magnetic fields.
The next milestone in understanding superconductivity occurred in 1933, when Walter Meissner and Robert Ochsenfeld discovered that a superconductor will repel an external magnetic field.
The currents induced in in a surface layer of a superconductor by a magnet placed close to it exactly mirror the field that otherwise would have penetrated the superconducting material, creating a zero field inside the material.

It is often referred to as perfect diamagnetism.
It was discovered by Walter Meissner and Robert Ochsenfeld in 1933.
In the effect, there is an exclusion of magnetic flux brought about by electrical "screening currents" that flow at the surface of the superconducting metal and which generate a magnetic field that exactly cancels the externally applied field inside the superconductor.

Super conductors were not really recognised until 1933 and the Meissner Effect and the phenomenon known as diamagnetism, up until which many people where very sceptical about the difference between conductors and super conductors.
Walter Meissner and Robert Ochsenfeld discovered the Meissner Effect which showed that superconducting materials repelled magnetic fields.

They determined that when a material was penetrated with a magnetic field, in its' superconductive state, it would create a current inside the superconductor.
