- The limiting condition may be found by putting it equal to zero.
- The box, I, has a hinged bottom with a projecting click finger which, as the box de - scends, plays idly over the staves of a ladder arc. When the weight is removed from the platform, the counterbalance, E, causes the finger, G, to run back to its zero position, carrying with it the finger M, and causing the click finger of the box, I, to trip open the bottom of the box and let the penny fall out.
- The lever, J, regains its zero position, and all is ready for another weighing.
- The steelyard is exactly in balance when there is no weight on the platform and Q is at the zero end of its run, at 0.
- By this means the zero of the scale on the drum can be adjusted to the fixed index on the casing when there are no goods on the platform.
- This lever is so counterbalanced that when there is no weight in the pan the pendulum is vertical, and the index arm should then stand at zero.
- The zero adjust - ment is effected by means of levelling screws in the base of the frame.
- By the second part of the drop the motion of the poise is reversed and the poise is run back to the zero From the Notice issued by the Standards Department of the Board of Trade, by permission of the Controller of H.M.
- When the poise is at the zero end, and there is no load on the platform, the end of the steelyard is down, and has locked the ratchet wheel by means of the pawl; the shaft being thus locked, the sprocket wheels are stopped, the drum-shaft runs free by the friction clutch, and the two pulleys which are connected by the crossed band are running idle.
- Consequently the motion of the mitre wheels is reversed and the poise is run back to zero.
- When the poise arrives at zero it frees the clutch which connects the pulley and the sprocket wheel, and the machine is then ready for the next load.
- The essential features which distinguish this from other systems are (I) the limitation of the number of different symbols, only ten being used, however large the number to be represented may be; (2) the use of the zero to indicate the absence of number; and (3) the principle of local value, by which a symbol in effect represents different numbers, according to its position.
- To prevent confusion the zero or " nought " is introduced, so that the successive figures, beginning from the right, may represent ones, tens, hundreds,.
- The zero, called " nought," is of course a different thing from the letter 0 of the alphabet, but there may be a historical connexion between them (§ 79).
- It is convenient to introduce the zero; thus 0 I 2345 6789 o I 2345 indicates that after getting to 4 we make a fresh start from 4 as our zero.

- Since represented 60, and o was the next letter, the latter appears to have been used to denote absence of one of the fractions; but it is not clear that our present sign for zero was actually derived from this.
- In calculating an average it should be observed that the addition of any numerical quantity (positive or negative) to each of the measurements produces the addition of the same quantity to the average, so that the calculation may often be simplified by taking some particular measurement as a new zero from which to measure.
- In mathematics, the term " infinite " denotes the result of increasing a variable without limit; similarly, the term " infinitesimal," meaning indefinitely small, denotes the result of diminishing the value of a variable without limit, with the reservation that it never becomes actually zero.
- In summer the temperature may rise as high as 106° F., while in winter it often sinks to 13° or even 20° below zero.
- The sheltered bays near Fiume enjoy an equable climate; but in all other districts the temperature in mid-winter falls regularly below zero, and the summer heats are excessive.
- At normal incidence the intensity of the reflected light, measured by the square of the amplitude, is { (µ -1) /(µ+ I) } 2 in both cases; but whereas in the former the intensity increases uniformly with i to the value unity for i =90°, in the latter the intensity at first decreases as i increases, until it attains the value zero when i -Fr = 90°, or tan i =,u - the polarizing angle of Brewster - and then increases until it becomes unity at grazing incidence.
- Thus A is zero at grazing incidence and at the critical angle, and attains its maximum value 7r-4 tan1 (I/p) at an angle of incidence given by sin e i=2/(p.2+I).
- The signs of the Peltier and Thomson effects will be the same as the signs of the coefficients given in Table I., if we suppose the metal s to be lead, and assume that the value of s may be taken as zero at all temperatures.

- The purpose of his paper was to show that if the axis, by which the observer imparts motion to the slide on which the travelling web is mounted, is provided with two disks at its extremities, so that the observer can use the thumb and finger of both hands in rotating it, there is no difficulty, after a little practice, in keeping the web constantly bisecting the star in transit, and that with a little practice the mean of the absolute errors in following the star becomes nearly zero.
