zero
has definitions from the fields of mathematics,arms


1 
[ noun ] a quantity of no importance
Examples "it looked like nothing I had ever seen before" "reduced to nil all the work we had done" "we racked up a pathetic goose egg" "it was all for naught" "I didn't hear zilch about it" Used in print (Kenneth Hoffman and Ray Kunze, Linear Al...)The projection * * f will be the identity on * * f and zero on the other * * f . We shall find a polynomial * * f such_that * * f is the identity on * * f and is zero on the other * * f , and so that * * f , etc. . Such an operator is obviously the zero operator ; for since it is nilpotent , the minimal polynomial for this operator is of the form * * f for some * * f ; but then since the operator is diagonalizable , the minimal polynomial cannot have a repeated root ; hence * * f and the minimal polynomial is simply x , which says the operator is 0 . Since * * f are linearly independent functions and the exponential_function has no zeros , these r functions * * f , form a basis for the space of solutions . (R. P. Jerrard, "Inscribed squares in plane curves"...)As s approaches T the square will be outside C and therefore both **f and **f must cross C an odd number of times as s varies from zero to T .

[ adjective ] indicating the absence of any or all units under consideration
Synonyms Examples "a zero score" Used in print (Organic Gardening and Farming,...)The plants took zero nights in their stride , with nothing but a mat of straw over the glass to protect them . (Harry H. Hull, "The Normal Forces and Their Ther...)The minimum total potential_energy is found by taking the derivative with_respect_to H and equating to zero . (James A. Ibers et al., "Proton magnetic resonance...)Field shifts were derived from the mean value of the resonance line , defined as the field about which the first_moment is zero . (Brand Blanshard, "The Emotive Theory," Robert...)And if we can see that what we meant to say remains the same , while the feeling varies from intensity to near zero , it is not the feeling that we primarily meant to express .

[ noun ] (mathematics) a mathematical element that when added to another number yields the same number
Used in print (J. F. Vedder, "Micrometeorites", in Francis S. J...)From an estimated mass of 25 g for a zero magnitude meteorite , the other masses are derived with the assumption of a mass decrease by a factor of 2.512 for each unit increase in magnitude . Note that the mass scale is one to two orders_of_magnitude greater than some previously used ; for_example , Jacchia ( 1948 ) derived a scale of 0.15 g for a * * f , zero magnitude meteorite . (R. P. Jerrard, "Inscribed squares in plane curves"...)On C , from the point P at **f to the point Q at **f , we construct the chord , and upon the chord as a side erect a square in such a way that as s approaches zero the square is inside C .
