If 1967 has been the first year of a relative decline with however many highlights, 1973 ( and more accurately his " after-Dallas 1972 ") has been the real start of Rosewall's true decline: admittedly he was still one of the best players but not one fighting for the first place.

Thus the view from Whitehall early in 1916: If defeat was not imminent, neither was victory ; and the outcome of the war of attrition on the Western Front could not be predicted.

If we attribute its apparent rate of rotation entirely to rotation in an inertial frame, a different " flatness " is predicted than if we suppose part of this rotation actually is due to rotation of the Universe and should not be included in the rotation of the galaxy itself.

If the two nations went to war, Adams predicted the president of the United States would use his war powers to abolish slavery.

If an individual coin toss or the roll of dice is considered to be a random event, then if repeated many times the sequence of random events will exhibit certain patterns, which can be studied and predicted.

If the vapor pressure is less than predicted ( a negative deviation ), fewer molecules of each component than expected have left the solution in the presence of the other component, indicating that the forces between unlike molecules are stronger.

If successful, the fast ignition approach could dramatically lower the total amount of energy needed to be delivered to the target ; whereas NIF uses UV beams of 2 MJ, HiPER's driver is 200 kJ and heater 70 kJ, yet the predicted fusion gains are nevertheless even higher than on NIF.

If the upper air is warmer than predicted by the adiabatic lapse rate (), then when a parcel of air rises and expands, it will arrive at the new height at a lower temperature than its surroundings.

If, on the contrary, the upper air is cooler than predicted by the adiabatic lapse rate, then when the air parcel rises to its new height it will have a higher temperature and a lower density than its surroundings, and will continue to accelerate upward.

If the predicted half-life falls into an experimentally accessible range, such isotopes have a chance to move from the list of stable nuclides to the radioactive category, once their activity is observed.

If the three arguments of a typical ditransitive verb are labeled D ( for Donor ; the subject of a verb like " to give " in English ), T ( for Theme ; normally the direct object of ditransitive verb in English ) and R ( for Recipient, normally the indirect object in English ), these can be aligned with the Agent and Patient of monotransitive verbs and the Subject of intransitive verbs in several ways, which are not predicted by whether the language is accusative, ergative, or active.

If there is little plasticity, the phenotype of an organism can be reliably predicted from knowledge of the genotype, regardless of environmental peculiarities during development.

If the model were true, the evidence would be exactly as likely as predicted by the current state of belief.

If the legend were true, and if the priests were able to move disks at a rate of one per second, using the smallest number of moves, it would take them 2 < sup > 64 </ sup >− 1 seconds or roughly 585 billion years or 18, 446, 744, 073, 709, 551, 615 turns to finish, much longer than the predicted lifespan of the sun.
