With disruptive discharge coils there are sudden rises of potential and the vacua are more quickly impaired, for the electrodes are deteriorated in a very short time.

In reality, however, the sum of our actions and cognitions is no series of facts and intervening vacua, but a continuous stream.

Hittorf examined the phenomena exhibited in so-called high vacua, that is, in exceedingly rarefied gases.

Trent settled deeper in his chair, his eyes lifted to the roaring funnels where volumes of smoke were sucked up as by invisible vacua.

In nearly all pumps for producing the high vacua necessary, e.g. for the electric glow-lamp and the X-ray tube, mercury is employed.
