| Description | This volume contains, first, a fairly substantial report of investigations and tests relative to the protection of kite-balloons from destruction in thunderstorms (1917-18). This involved measurement of the current from a point-discharger, investigations of the properties of various types of fabric and incidentally, much thinking on fundamental simple physics.
Interspersed are various general notes on thunderstorms and lightning, interesting as showing how his ideas were developing. |
