It was a matter of principle with Churchill, since Britain had declared war in behalf of Poland.

`` You see, first of all and in a sense as the source of all other ills, the unshakeable American commitment to the principle of unconditional surrender: The tendency to view any war in which we might be involved not as a means of achieving limited objectives in the way of changes in a given status quo, but as a struggle to the death between total virtue and total evil, with the result that the war had absolutely to be fought to the complete destruction of the enemy's power, no matter what disadvantages or complications this might involve for the more distant future ''.

He contends this idea doesn't conflict with experiments on which the principle of conservation of matter and energy is based because some slight error must be assumed in such experiments.

In principle, it removes any doubt as to the exact nature of the defendant's guilt in the matter.

Specifically, it can be used to test the equivalence principle, to probe dark matter, and test neutrino physics.

An experiment can show the particle-like properties of matter, or the wave-like properties ; in some experiments both of these complementary viewpoints must be invoked to explain the results, according to the complementarity principle of Niels Bohr.

In Taoism, qi functions similarly to pneuma in terms of a prime matter ( a basic principle of energetic transformation ) that accounts for both biological and inanimate phenomena.

The Valentinian Heracleon interpreted the devil as the principle of evil, that of hyle ( matter ).

Materialism is a realist philosophy of science, which holds that the world is material ; that all phenomena in the universe consist of " matter in motion ," wherein all things are interdependent and interconnected and develop according to natural law ; that the world exists outside us and independently of our perception of it ; that thought is a reflection of the material world in the brain, and that the world is in principle knowable.

Hard euroscepticism is the opposition to membership of, or the existence of, the European Union as a matter of principle.

A seminal work by Dyson came in 1966 when, together with Andrew Lenard and independently of Elliott H. Lieb and Walter Thirring, he proved rigorously that the exclusion principle plays the main role in the stability of bulk matter.

The principle of inertia is one of the fundamental principles of classical physics which are used to describe the motion of matter and how it is affected by applied forces.

This is known as the Pauli exclusion principle, and it is the fundamental reason behind the chemical properties of atoms and the stability of matter.

Moreover, the majority of cosmologists take the cosmological principle as a given, which assumes that matter at the scale of billions of light years is distributed isotropically.

In Conservative and Reform Judaism, and some movements within Protestant Christianity, including process theology and open theism, deities are said to act in the world through persuasion, and not by coercion ( for open theism, this is a matter of choice — a deity could act miraculously, and perhaps on occasion does so — while for process theism it is a matter of necessity — creatures have inherent powers that a deity cannot, even in principle, override ).

File: Pauli. jpg | Wolfgang Pauli ( 1900-1958 ): pioneers of quantum physics, received the Nobel Prize in Physics in 1945 ( nominated by Albert Einstein ), formulated the Pauli exclusion principle involving spin theory ( underpinning the structure of matter and the whole of chemistry ), published the Pauli – Villars regularization, formulated the Pauli equation, coined the phrase ' not even wrong '

Perjury operates in American law as an inherited principle of the common law of England, which defined the act as the " willful and corrupt giving, upon a lawful oath, or in any form allowed by law to be substituted for an oath, in a judicial proceeding or course of justice, of a false testimony material to the issue or matter of inquiry.

As such, the Pauli exclusion principle underpins many properties of everyday matter, from its large-scale stability, to the chemical behavior of atoms.

However, stability of large systems with many electrons and many nuclei is a different matter, and requires the Pauli exclusion principle.

It has been shown that the Pauli exclusion principle is responsible for the fact that ordinary bulk matter is stable and occupies volume.

A more rigorous proof was provided in 1967 by Freeman Dyson and Andrew Lenard, who considered the balance of attractive ( electron – nuclear ) and repulsive ( electron – electron and nuclear – nuclear ) forces and showed that ordinary matter would collapse and occupy a much smaller volume without the Pauli principle.

In 1995 Elliott Lieb and coworkers showed that the Pauli principle still leads to stability in intense magnetic fields such as in neutron stars, although at a much higher density than in ordinary matter.

Although observance of, or disregard for, the Law was primarily a matter of political expediency rather than legal principle, it was broadly understood to prevail in domains that were originally Frankish or at some time accepted Salian Frankish juridical principles.

In the context of quantum mechanics, the wave – particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects.

In quantum field theory, this process is allowed only as an intermediate quantum state for times short enough that the violation of energy conservation can be accommodated by the uncertainty principle.

Although this concept remains a guiding principle of the profession, it is a concept that has been widely critiqued within the conservation profession and is now considered by many to be " a fuzzy concept ".

Another important principle of conservation is that all alterations should be well documented and should be clearly distinguishable from the original object.

This principle, the conservation of energy, was first postulated in the early 19th century, and applies to any isolated system.

If one takes the experimentally observed flow around an airfoil as a starting point, then lift can be explained in terms of pressures using Bernoulli's principle and conservation of mass.

It is a statement of the principle of the conservation of energy applied to flowing fluids.

Naturalist Paul R. Ehrlich wrote that the Passenger Pigeon's extinction " illustrates a very important principle of conservation biology: it is not always necessary to kill the last pair of a species to force it to extinction.

The first law observes that the internal energy of an isolated system obeys the principle of conservation of energy, which states that energy can be transformed ( changed from one form to another ), but cannot be created or destroyed.

Where divergence is occurring in the upper atmosphere, there will be air coming in to try to balance the net loss of mass ( this is called the principle of mass conservation ), and there is a resulting upward motion ( positive vertical velocity ).

The positivity of energy release in these processes means that they are allowed kinematically ( they do not violate the conservation of energy ) and, thus, in principle, can occur.

His chief work is his Hydrodynamique ( Hydrodynamica ), published in 1738 ; it resembles Joseph Louis Lagrange's Mécanique Analytique in being arranged so that all the results are consequences of a single principle, namely, conservation of energy.

How the Self Controls Its Brain is a book by Sir John Eccles, proposing a theory of philosophical dualism, and offering a justification of how there can be mind-brain action without violating the principle of the conservation of energy.

An Aristotelian could take a position on the spectrum between the view that the non-existence of the void was just a brute fact ( like the non-existence of unicorns ) or it was a high principle of physics ( like conservation of energy ).

In principle their role is to maintain documented collections of living plants for the purposes of scientific research, conservation, display and education, although this will depend on the resources available and the special interests pursued at each particular garden.

Casimir combined the projected rate of change in zero-point energy with the principle of conservation of energy to predict a force on the plates.

This has become a core principle of conservation biology and has remained so in recent resolutions-including the World Charter for Nature in 1982, the Rio Declaration at the Earth Summit in 1992, and the Johannesburg Declaration 2002.

At all times, the institution ( in all its forms ) has heavily emphasized as a key operating principle the strong need to cater to and address the needs of local nations, communities and peoples, so that those nations, communities and peoples can take ownership of future, long term conservation goals and objectives in their local areas:

His theory was at once mathematical and mechanical ; it contained the principle of the conservation of heat ( later understood as an instance of conservation of energy ) and even contained the concept ( although not the label ) of the mechanical equivalent of heat.

A further principle of conservation was stated by Epicurus ( 341 – 270 BCE ) who, describing the nature of the universe, wrote that " the totality of things was always such as it is now, and always will be ".

A principle of the conservation of matter was also stated by Nasīr al-Dīn al-Tūsī ( 1201 – 1274 ) during the 13th century.

The principle of conservation of mass was first outlined clearly by Antoine Lavoisier ( 1743 – 1794 ).

Wollaston used his Bakerian lecture in 1805, On the Force of Percussion, to defend Gottfried Leibniz's principle of vis viva, an early formulation of the conservation of energy.
