Magnetism and an electricity. Otto Gerike

you are: Magnetism and an electricity

Existence of atmospheric pressure has been shown in 1654 in one of the most impressing physical experiments spent by then, - in experiment with the Magdebourg hemispheres which has been thought up by the German physicist Otto Gerike (1603-1686), the rich person who is pursuing science for the sake of own pleasure who has invented the air pump and has carried out with it a number of experiences. Rough energy and obstinacy replaced Gerike a profound knowledge and have allowed it to reach considerable results.

It has made the big efforts to receive vacuum (pusgotu), using primitive means. Knowledge and experience came in the course of works. By means of the vacuum pump as a result of very effective experiences of Gerike it was possible to find out the nature of atmospheric pressure. Numerous supervision have led to its thought that occurrence of clouds, winds, fogs and other atmospheric phenomena speaks change ' density ' air which he has decided to define (that eventually was possible to it).

Gerike was engaged as well in an electrostatics: has noticed pushing away of the particles electrified equally, has designed the first electric car.

It liked to surprise people effective experiences. During congress in Regens-burge in 1654 Gerike has shown gathered the well-known experiment with the Magdebourg hemispheres: from the sphere formed by joined hemispheres, have pumped out air, and teams from eight horses, located with each party could break off them only. Experience has caused general surprise and admiration.
