Experimenta Nova

"This remarkable work on experimental philosophy ranks next to Gilbert's in the number and importance of the electrical discoveries described. Electric conduction and repulsion, the discharging power of points, the dissipation of charge by flames, the light due to electrification, the crepitating noises of small sparks are all recognized." Wheeler Gift Cat. 170

"A book of prime importance in electrical discovery, air-pressure and the vacuum pump. Described are electric conduction and repulsion and the discharging power of points. Guericke constructed a spherical rotor of sulphur mounted on a crank; its rotation and contact upon it generated the first visible and audible electric sparks." -Dibner 55

FIRST EDITION OF ONE OF THE GREAT SCIENTIFIC CLASSICS: "Describes the invention of the air pump and the famous experiment with the Magdeburg hemispheres, in which two teams of eight horses were employed in an attempt to pull apart two copper hemispheres from which the air had been withdrawn. Guericke also describes the invention of the first electrical machine, which generated the first visible and audible electric charges” (Honeyman).

"In 1650 Guericke constructed the first air pump, which he used to create a vacuum in various containers. He showed that sound would not travel in a vacuum, and furthermore that a vacuum would not support combustion or animal life. In 1654 Guericke gave an impressive demonstration in front of the emperor Ferdinand III, of the force of atmospheric pressure. Two identical copper hemispheres 12 feet (3.66 m) in diameter were joined together. When the air was pumped out, 16 horses could not pull them apart although when the air reentered the hemispheres they fell apart by themselves. He also showed that 20 men could not hold a piston in a cylinder once the air had been evacuated from one end of it... In 1663 he built the first electrical friction machine by rotating a sulfur globe against a cloth... The results of these and other experiments were published in his Experimental nova Magdeburgica de vacuo spatio (1672; New Magdeburg Experiments Concerning Empty Space)" (Biographical Encyclopedia of Scientists).

The magnificent large folding plate of the great public experiment with the horses and hemispheres is one of the most celebrated and reproduced images in all of science.
