International Year of Crystallography 2014
2014 will go down in history as the international year of crystallography. What do we mean by crystallography? Crystallography is the science of crystals, their structure and symmetries, forma- tion or creation and their properties and potential applications. It is the only disci- pline which answers the question: what is the atomic structure of materials? Crystallography looks at the inner sym- metries of materials, which are also out- wardly visible on the cleavage surface. It is a subject that even fascinated the an- cients. The very first crystallographer was the philosopher and naturalist Theo- phrastos of Eresus (371–287 B.C.) – who, incidentally, was a pupil of Aristotle. Crystals suggest that, in the natural world, the arrangement of atoms is gov- erned by certain structural principles which can be described in mathematical terms.

100 Years Swiss National Park
More than 100 years ago, a group of dedicated conservation- ists from the Natural Science Society set themselves the goal of conserving an area of Switzerland’s mountain landscape in the Lower Engadine for posterity. In 1909, they founded the nature conservation organization Bund für Naturschutz (now Pro Natura) and leased the Val Cluozza area near Zernez. In 1914, the Swiss National Park (SNP) was officially estab- lished in the easternmost corner of Switzerland, the first of its kind in Central Europe. Since then, the SNP has evolved into a centre of education about the natural world which brings the public closer to nature and the wild. Each year, around 150,000 visitors make use of the SNP’s diverse facilities. The 21 tours with different profiles provide a fascinating insight into to the 170-kilometre-square park.

125 Years Of Swiss Army Post
For 125 years, the Army postal service has been making soldiers’ lives sweeter with sumptuous food parcels and passion- ate love letters. There’s no doubt that, even for the “iPhone generation”, the Army post exerts an emotional pull. Somebody who knows this only too well is adjutant corporal Thomas Ramseier, a military postman in the Swiss Army.Each year, the Army postal service deliv- ers two million letters, a quarter of a mil- lion parcels and 1.3 million newspapers supplied free of charge by the publishers to their recipients – and postage is free up to five kilos.

100 Years Swiss Air Force
Although balloons sporting the Swiss na- tional colours took to the skies in the early part of the 20th century, the first Swiss air squadron was not assembled until the start of World War One. However, its commander, cavalry instructor Theodore Real, had scarcely any resources at his disposal, and had to mobilize private air- craft owners, most of them from western Switzerland, who brought their own me- chanics with them. Three foreign aircraft were also requisitioned. From August 1914, the squadron was stationed in the balloon hangar on the “Beundenfeld” in Berne. However, the site was ill-suited to training the pilots, so, at the end of 1914, the squadron had to relocate to Düben- dorf near Zurich. The pilots were seldom deployed during the war. It wasn’t until the interwar period that the air force gained in importance, and, in addition to Dübendorf, other military airbases were established in Thun, Laus- anne and Payerne. The first fleet of air- craft ordered by official quarters were Häfeli DH-3s. Issue Date: 06.03.2014 Designer: Fredy Trümpi, Binz (ZH) Process: Offset Colours: 4 Colours Size: 33×28 mm

So-called mychor- rizal fungi have a close symbiotic relationship with tree roots and improve the absorption of nutrients and water by woodland trees, while pathogenic fungi regulate biodiversity in the forest.Fungi propagate by means of microscopically small spores which are formed on the underside of the cap in the shape of gills, tubes, ridges or spikes and are spread by the wind. If, for instance, you tread on a puffball, you’ll see a dark cloud of spores escape.
The chanterelle is one of the most popu- lar edible mushrooms and has a delicate, apricot-like flavour. This my chorrizal mushroom is widespread in deciduous and coniferous forests and grows best in acidic soils. The sooty milkcap is commonly found in alpine co- niferous forests, as a mychorrizal partner to the spruce. It is prized as an edible mushroom and has an attractive, velvety surface. When damaged, it re- leases a white milky substance which turns salmon pink when it hits the air.
