What reading level is The Edison Effect book?
To quickly assess the difficulty of the text, read a short excerpt:
He appreciated the necessity for vastly improving the vacuum of DeForest's tube, and this he was able to do after having obtained a superior vacuum pump from Europe.
The DeForest audion with which Arnold started was valuable as a detector and amplifier of feeble radio currents. It was, however, incapable of satisfactorily amplifying the feeble but much larger currents of wire telephony.
Arnold, who was one of the earliest scientific workers in ther- mionics, realized that to improve DeForest's ...tube he must produce a pure thermionic effect, free of gas complications. In this connec- tion, he recognized the existence and importance of the space charge effect of electrons in the vacuum tube and the necessity for the cal- culation of the magnitude of this effect and of the methods for its adaptation to commercial purposes.
As a result of Arnold's work on his vacuum tube, together with the results of research which had to be conducted in more than 100 other particulars, long-distance telephone service was extended from New York to Denver late in 1914, and soon after that long-distance telephony was extended from New York to San Francisco.
