Accepting the claim of the preface to the Experimenta Nova that the entire work had been essentially completed before March 1663, von Guericke can be fairly credited with inventing a primitive form of frictional electrical machine before 1663.

All of von Guericke's work on the vacuum and air pressure is described in Book III of the Experimenta Nova (1672).

Although the Experimenta Nova does contain correspondence from 1665, there is no reason to doubt von Guericke's assertion that the work was essentially finished by March 1663.

In the Experimenta Nova, Book III, Ch. 34, he relates how he first became aware of Torricelli 's mercury tube experiment from Valerianus Magnus at Regensburg in 1654.

Other research In the Experimenta Nova, Book III, Chapter 20, von Guericke reports on a barometer he had constructed and its application to weather forecasting.

Von Guericke describes his work on electrostatics in Chapter 15 of Book IV of the Experimenta Nova.
