Town of Bamberg,Germany.

Bamberg is located in southern Germany in the north of Bavaria. It is a good example of a central European town with a basically early medieval plan and many surviving ecclesiastical and secular buildings of the medieval period.In the late 18th century it was the centre of the Enlightenment in     southern Germany, with eminent philosophers and writers such as Hegel and Hoffmann living there.

2015 International Year of Light-Issue Date: 02.03.2015

Sunlight is an essential life requirement for humans, animals and plants. Light in general is also a key issue in science and culture. The United Nations has declared 2015 the International Year of Light: 1000 years ago, it was first proved that light sources emit radiation, exactly 200 years ago, the natural wave of light was discovered and the quantum theory of light 110 years ago. Experimenting with light has awoken curiosity for science. The special stamp "play of light"  allows the viewer to perform three experiments with respect to the mentioned anniversaries. Thanks to the fluorescent colour of the background the stamp glows in the dark. It is a light source, if it has been irradiated by the sun. The wave theory can be observed by holding the stamp in front of a light source. The micro-perforations in the paper are clearly visible in the light waves that are diffracted by the small openings. For the experiment, the quantum theory of pink curve was printed in the background of the globe with a special colour. Upon irradiation with UV light, the colour changes from pink to violet.
