1983: Europa - Inventions (Design - Jünger) |
An alphabet for the alphabet round of Sunday Stamps. Here is a celebration of moveable type, or as the stamp says, the 'Invention of the Art of Printing'
It features a modern letter A against the background of the historic letters of the printing revolution by Johannes Gutenberg.
The other genius chosen for this stamp set of inventions was Heinrich Hertz and the discovery of electromagnetic waves. The card shows his experimental Oscillator. At the end are two hollow zinc spheres. The spheres are connected to copper wires which run into the middle where there is a gap for the sparks to jump between.
Hertz's experiment proved that radio waves and light waves were part of the same family , which today we call the electromagnetic spectrum. Hertz said "I do not think the wireless waves I have detected will have any practical application". He wouldn't live to see that statement disproved. The stamp shows a representation and image of the electric field lines.
