It was found that, if the medium held her fingers at a distance of an inch or so from the knob of the electroscope, some form of energy, apparently _radio-active_ in character, issued from her fingers, and _gradually discharged the electroscope_. ❋ Hereward Carrington (1919)
By the side of gold leaf electroscopes we see a feather electroscope, which is fastened to its support by means of a silken thread. ❋ Various (N/A)
The spectroscope will detect a quantity of matter four million times smaller even than this; and the electroscope is a million times still more sensitive than the spectroscope. ❋ J. Arthur Thomson (1897)
The leaves of the electroscope were wide apart, while the inked line on the automatically revolving drum rose steadily, indicating the continued increase of cosmic rays. ❋ Johnny Pez (2010)
The next instant Pat beheld drum, electroscope, everything within his range of vision, swim before his eyes in a distorting heat haze, while at the same time the air about him became like the stifling breath of a furnace. ❋ Johnny Pez (2010)
Pat looked at his electroscope, and saw that it indicated a noticeable increase in the presence of cosmic rays. ❋ Johnny Pez (2010)
He turned to the electroscope and its revolving drum; one of the most important pieces of apparatus on board, so far as the purpose of the expedition was concerned. ❋ Johnny Pez (2010)
He's playing an electroscope blues like a hurricane, ❋ Unknown (2009)
Despite their wide usage, instruments such as the gold leaf electroscope and the spinthariscope designed by William Crookes were not accurate and precise enough to be employed for the measurement of uranium rays. ❋ Unknown (2007)
When it turned out that one of his colleagues who had worked with radioactive substances for several months was able to discharge an electroscope by exhaling, Rutherford expressed his delight. ❋ Unknown (1996)
An electroscope measured the tension between two aluminum plates in the Vacor Tube. ❋ Unknown (1990)
The so-called "natural leak" of charge from a statically-charged electroscope is significantly slowed down within the accumulator (7). ❋ Unknown (1990)
The natural leak from the electroscope within the accumulator is slowed because the electroscope discharges into a higher orgone concentration than exists in the outside air. ❋ Unknown (1990)
To = temp above accumulator; Ti = temp within; T = control (room temp) El = electroscope; = direction of radiation. ❋ Unknown (1990)
Another means of objectifying the presence of an anomalous energetic force is the behaviour of a static electroscope placed within the enclosure. ❋ Unknown (1990)
By breaking up pitchblende into its chemical components and examining, again with the aid of the electroscope, the radioactivity of the products that were obtained, they at last managed by means of a series of solutions and precipitates to isolate the materials that were distinguished by radioactivity of extraordinary intensity. ❋ Unknown (1967)
M. and Mme. Curie, having thus found with the aid of the electroscope that the radioactive properties of the mineral pitchblende were more marked than those of uranium, came to the conclusion that pitchblende must contain one or more new radioactive substances. ❋ Unknown (1967)
The electroscope has thus to some extent played the same part in respect of radioactive materials as the spectroscope in the search for new elements. ❋ Unknown (1967)
As a result, if rays of this kind fall on an electroscope charged with electricity, it will discharge more or less quickly, according to the greater or lesser activity of these rays which make the air round the electroscope a conductor. ❋ Unknown (1967)
After Schmidt and Madame Curie's discovery in 1898 that compounds of thorium and the minerals containing it possessed properties similar to those of uranium, Owens found that the power of discharging an electroscope could be greatly modified by blowing a current of air over the specimen. ❋ Unknown (1966)
