	Negative proof (Site not responding. Last check: 2007-10-25)
		The fallacy of negative proof is a type of logical fallacy of the following form: : "No one has produced an example of one; therefore it doesn't exist." While the assertion has some strength as an epistemic directive, logically it has none.

	Proving a Negative
		And to test the negative proposition one merely has to look in the box: since crows being in the box (p) entails that we would see crows when we look in the box (q), if we find q false, we know that p is false.
		This is not "proof" in the same sense as a mathematical proof, which establishes that something is inherent in the meaning of something else (and that therefore the conclusion is necessarily true), but it is proof in the scientific sense and in the sense used in law courts and in everyday life.
		Negative statements often make claims that are hard to prove because they make predictions about things we are in practice unable to observe in a finite time.

	Negative proof - Wikipedia, the free encyclopedia
		The fallacy of appealing to lack of proof of the negative is a type of logical fallacy of the following form:
		But it is not logical to argue that something exists simply because there is no proof to the contrary; one cannot say, "No one has proven that aliens do not exist.
		However, the converse is also true, according to the Argument from Ignorance: One also cannot say that, "I have not seen proof that something supernatural exists, therefore a supernatural force cannot exist".

	Combination photographic negative and proof holder - Patent 5195683
		A film negative and matching proof are held for storage in a receptacle formed from a unitary body of flexible material folded to form panels positioned in overlying relation to form a first pocket and a second pocket.
		Generally, the negative is maintained in a glassine receptacle, and the proof clipped to the receptacle so that the negative and the proof are not separated from one another.
		The proof 77 is handled to a greater extent than the negative 75 for examination purposes and therefore, it is convenient to be able to insert and remove the proof 77 from the pocket 76 that is open along two edges.

	A Rigorous Proof of Negative Exponents
		Exact symbolical proof leads one into calculus and indeterminate forms that also depend upon the negative exponent conjecture and so it will not be prosecuted here.
		In general, it is difficult to prove that z^0 = 1 without proving the negative exponent conjecture as it is difficult to prove the negative exponent conjecture without proving that z^0 = 1.
		The negative exponents, therefore, generate fractions as a consequence of the monotonic nature of the powers of a radix and the pattern established in the sequence generated by monotonically decreasing exponents of that radix.

	Process for surface improvement of surprint proof involves exposure thru halftone screen tint - Patent 4321320
		The multilayer surprint proofs having a positive-working photosensitive outer layer upon ageing exhibit cracks or crazes in the surface thereof.
		In practicing the process of the invention the tacky surface of the negative-working surprint proof that is modified and improved is a photosensitive tacky layer of a positive-working photohardenable element.
		After the negative-working multicolor surprint proof with the positive-working photohardenable element present thereon is prepared, the surprint proof is exposed through a screen tint as described more fully below, the protective film of the exposed positive-working element is removed and an admixture of particulate material and carrier particles is applied to the exposed tacky surface.

	APUG - POP info-"Bullet proof negative" comment
		I take bullet proof negative to mean a negative so dense that exposure times under an enlarger head would be in the tens of minutes - in other words, they will not respond at all to enlarging.
		A "bullet proof" negative is one that has been overexposed by one or more stops and that has also been developed to a high density range.
		Such negatives will usually print well with alt processes and AZO but exposure times can be two to four times as long as would be required had the negative received normal exposure.

	The reality of negative refraction (May 2003) - Physics World - PhysicsWeb
		In contrast, the beam that emerged from a metamaterial wedge that was made from a grid of rings and wires exited at a negative angle for certain frequencies.
		To make sure that the observed beam was due to the inherent negative index of the wedge - as opposed to an artefact associated with the sample being lossy or diffractive - the team used two different wedge samples so that waves would be incident on the metamaterial at two different angles.
		Both cases exhibited negative refraction at angles that were consistent with the sample having a well defined negative index - confirmation of Snell's law for a negative refractive index.

	Method for producing a positive or negative color-proof using the same materials - Patent 6057077
		When making a colour proof, it is usual to generate single-colour images corresponding to the primary colours of multicolour printing in succession on an image-receiving material or to transfer these images to an image-receiving material.
		The material described therein consists of a film support having a release surface, a photosensitive layer on said release surface, which photosensitive layer is simultaneously coloured in one of the primary colours of multicolour printing, and a thermoplastic adhesive layer.
		The basis for image differentiation in the positive and negative procedures is an increase in the adhesive strength between the photosensitive layer (2) and the coloured layer (4) during exposure.

	rinku: positive and negative statements
		one of the most useful epistemologic principles is the burden of proof principle -- the idea is that those who make a positive statement (statements of fact) have the burden of proof, whereas negative statements (statements of doubt or negation) do not.
		i believed (and still believe) the second of those is the negative statement, and the first the positive statement, because the first is a statement of something that exists ('negligability of minute changes' is true), and the second is a statement of something that doesn't exist ('negligablity of minute changes' is false).
		I think that the burden of proof is on the one who asserts that a small change in velocity would not effect electron behavior.

	Peter Suber, "Infinite Sets"
		In a negative proof we assume the negation of the desired conclusion and show that that assumption leads to a contradiction; then we conclude that assumptions is false, which is the same thing as to conclude that the desired conclusion is true.

		Anyway, all high-density negative ion generators can generate a tiny amount of ozone near the ionizer.
		And we will only sell ozone-only units to people who actually need them (they must be ordered by phone), so the ozone will be destroyed by the odors they need to get rid of, and so will not build up.
