If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called " black ".

If there are other stars orbiting a black hole, their orbit can be used to determine its mass and location.

If the vanes are made of metal, then the black or white paint can be the insulation.

If van der Heul was indeed of African ancestry, this fact would make him the highest ranking black pirate so far identified.

If someone decides to donate to help orphan children, but decides to donate less, say, to black children out of a racist attitude, he or she will be acting in a discriminatory way even the people he discriminates against are actually benefitted by having some money donated to them.

If this is the case, from here on, we see an insidious assault of his faculties, manifesting as paranoid features in his paintings, culminating in his black paintings and especially Saturn Devouring His Sons.

If the stool was very black, the patient died.

If one throws a hot gas with entropy into a black hole, once it crosses the horizon, the entropy would disappear.

If neighboring geodesics start moving toward each other they eventually collide, at which point their extension is inside the black hole.

Louis Farrakhan has stated " If you look at the human family — now, I'm talking about black, brown, red, yellow and white — we all seem to be frozen on a subhuman level of existence.

If all the components are at zero the result is black ; if all are at maximum, the result is the brightest representable white.

If a B-tree cluster contains only 1 value, it is the minimum, black, and has two child pointers.

If a cluster contains 3 values, then the central value will be black and each value stored on its sides will be red.

If the cluster contains two values, however, either one can become the black node in the red – black tree ( and the other one will be red ).

If white people were already sitting in the front, black people had to board at the front to pay the fare, then disembark and reenter through the rear door.

If the mass of the core exceeds the Chandrasekhar limit, electron degeneracy pressure will be unable to support its weight against the force of gravity, and the core will undergo sudden, catastrophic collapse to form a neutron star or ( in the case of cores that exceed the Tolman-Oppenheimer-Volkoff limit ), a black hole.

If he / she is extremely black, he / she is adlam ( dalam ).

") or a hypothetical one (" If one were to build an unobtainium shell around a black hole's event horizon, what would happen to the material piling up on it?

: If we are justified in assuming that the scope of the generalization ' All ravens are black ' can be restricted to ravens, then this means that we have some outside information which we can rely on concerning the factual situation.

Some approaches to the paradox have sought to find other ways of interpreting " If then " and " All are " which would eliminate the perceived equivalence between " All ravens are black " and " All non-black things are non-ravens.

" If is a raven then is black " is equivalent to " If were not black then would not be a raven ".

If notched for the battens, they would require more work, be weakened and limber holes would have to be bored so that bilge water could flow through.

If I could put your body in an imaginary atomic press and squeeze you down, squeeze these holes out of you in the way we squeeze the holes out of a sponge, you would get smaller and smaller until finally when the last hole was gone, you would be smaller than the smallest speck of dust that you could see on this piece of paper.

If the holes are closed, the gas will only mix with ambient air at the point of combustion, that is, only after it has exited the tube at the top.

If the carriers are holes, replace electron density by the negative of the hole density.

If the holes are too big the steamer can be lined with damp cheesecloth.

If there were no holes then a loop of rope kept the oars in place.

If the alarm indicates a hawk diving toward the colony, all the prairie dogs in its flight path dive into their holes, while those outside the flight path stand and watch.

If the crystal were of any reasonable size, the number of electrons ( or holes ) required to be injected would have to be very large, making it less than useful as an amplifier because it would require a large injection current to start with.

If these holes are left in the emulsion, the ink will continue through and leave unwanted marks.

If the holes bored into the thwarts are indeed meant to accommodate a dummy crew, the crew seating would have been arranged with two men per bench amidships, and one man per bench fore and aft where the ship narrows so that there is only room for one man.

If a pilot looked across the cockpit towards the other pilot's display monitors, he saw distortions or even " black holes " because his viewing angle was outside the viewing volume established for the display units concerned.

If an insufficient twist rate is used, the bullet will begin to yaw and then tumble ; this is usually seen as " keyholing ", where bullets leave elongated holes in the target as they strike at an angle.

If we take the modules to be over a field, then the dimension of the n-th homology of X turns out to be the number of " holes " in X at dimension n.

If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole.

If you consider the beam when it is sweeping across the middle area of the screen, the three beams from the individual guns are each traveling the same distance and meet the holes in the mask at equal angles.

If the carriers are holes, replace electron density n by the negative of the hole density p.

If the speeds are not matched, the dog teeth on the collar will " crash " or grate as they attempt to fit into the holes on the desired gear.

If you blow up an icosahedron by moving the faces away from the origin the right amount, without changing the orientation or size of the faces, and do the same to its dual dodecahedron, and patch the square holes in the result, you get a rhombicosidodecahedron.

If there is a node for each possible ID, the successor of node 2 is node 3, and the predecessor of node 1 is node 0 ; however, normally there are holes in the sequence.

If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole.

If one only considers black holes classically, then they have zero temperature and, by the no hair theorem, zero entropy, and the laws of black hole mechanics remain an analogy.

If it is, then many things that we would normally consider to be demonstrably impossible can be logically possible: for example, that travel might be possible at speeds faster-than-light or that escape from black holes is not impossible.

If some versions of string theory are correct, then high-energy cosmic rays could create black holes when they collide with molecules in the Earth's atmosphere.
