Even so, today the overwhelming majority of builders opt for flat ( or slightly radiused ) tops and backs.

Even before its publication, the Liberal Party of Quebec gave a flat refusal to the constitutional option promoted by René Lévesque in his essay.

Even light itself does not have a " velocity " of c in this sense ; the total velocity of any object can be expressed as the sum where is the recession velocity due to the expansion of the universe ( the velocity given by Hubble's law ) and is the " peculiar velocity " measured by local observers ( with and, the dots indicating a first derivative ), so for light is equal to c (- c if the light is emitted towards our position at the origin and + c if emitted away from us ) but the total velocity is generally different than c .( Davis and Lineweaver 2003, p. 19 ) Even in special relativity the coordinate speed of light is only guaranteed to be c in an inertial frame, in a non-inertial frame the coordinate speed may be different than c ; in general relativity no coordinate system on a large region of curved spacetime is " inertial ", but in the local neighborhood of any point in curved spacetime we can define a " local inertial frame " and the local speed of light will be c in this frame, with massive objects such as stars and galaxies always having a local speed smaller than c. The cosmological definitions used to define the velocities of distant objects are coordinate-dependent-there is no general coordinate-independent definition of velocity between distant objects in general relativity ( Baez and Bunn, 2006 ).

Even though it is impossible to make perfect copies of an unknown quantum state, it is possible to produce imperfect copies.

Even with the defining postulates of both Einstein's theory of general relativity and quantum theory being indisputably supported by rigorous and repeated empirical evidence and while they do not directly contradict each other theoretically ( at least with regard to their primary claims ), they have proven extremely difficult to incorporate into one consistent, cohesive model.

Even so, classical physics can often provide good approximations to results otherwise obtained by quantum physics, typically in circumstances with large numbers of particles or large quantum numbers.

Even before the laws of quantum mechanics were developed to their present level, the radioactivity of such elements has posed a challenge to determinism due to its unpredictability.

Even so, this does not get rid of the probabilities, because we can't do anything without using classical descriptions, but it assigns the probabilities to the classical approximation, rather than to the quantum reality.

Even Albert Einstein did not consider it a satisfactory answer to the quantum non-locality question.

Even less familiar are Carbon nanotubes, the quantum wire and Luttinger liquid with their 1-dimensional topologies.

Even our quantum physics validate ideas the Buddha taught 2, 500 years ago.

In quantum mechanics, the concept of a point particle is complicated by the Heisenberg uncertainty principle: Even an elementary particle, with no internal structure, occupies a nonzero volume.

Even if an elementary particle has a delocalized wavepacket, the wavepacket is in fact a quantum superposition of quantum states wherein the particle is exactly localized.

Even advanced concepts in computation, such as fuzzy logic, knowledge-based systems and quantum computation have absolutely no use whatsoever for the extreme expressiveness of any of the world's languages anyway, " rich and powerful " as they may be characterized ; the notions understood by computers are very basic.

Even if the initial state could be polarized ; for example, by placing it in a magnetic field, the non-spherical decay pattern is still properly described by quantum mechanics.

Even though molecules were known before, their stability could not be explained by classical physics, but is due to the discrete nature of quantum mechanics.

Even to herself Helva sounded a little self-pitying but the truth was she was lonely, sitting on the darkened field.

Even though the author of the book states that Ruth " just happens " to find Boaz's field ( Ruth 2: 3 ), the reader may be led to accede to the notion that in Bible terms there is no mere chance, but that chance and God's providence amount to the same thing.

Even with no external electric field applied, these electrons move about randomly due to thermal energy but, on average, there is zero net current within the metal.

Even numbered years the NL had home field advantage.

Even when an object's net charge is zero, charge can be distributed non-uniformly in the object ( e. g., due to an external electromagnetic field, or bound polar molecules ).

Even in the presence of the field there is only a small induced magnetization because only a small fraction of the spins will be oriented by the field.

Even in the field of science, the practices of which were once viewed as being merely the objective testing and reporting of knowledge, scientists must persuade their audience to accept their findings by sufficiently demonstrating that their study or experiment was conducted reliably and resulted in sufficient evidence to support their conclusions.

Even assuming an electric field has been established, the mechanism by which the lightning discharge begins is not well known.

Even the “ hobbyist ” end of the field can break down into several distinct categories such as: observing deep sky objects, observing the planets, solar observing, lunar observation, and astrophotography of all those class of objects.
