Switzerland, officially the Swiss Confederation, is a landlocked country located at the intersection of Central, Western, and Southern Europe. It is bordered by Germany to the north, France to the west, Austria and Liechtenstein to the east, and Italy to the south. Switzerland is geographically divided among the Swiss Alps, the Swiss Plateau, and the Jura Mountains; the Alps cover most of the country's territory, whereas the majority of its 9 million people are concentrated on the plateau, which hosts many of the largest cities and economic centres, including Zurich, Geneva, Basel, Bern, Lausanne, Winterthur, and Lucerne.
Switzerland is a federal republic composed of 26 cantons, with Bern serving as the federal city and the seat of the national government. The country encompasses four principal linguistic and cultural regions—German, French, Italian, and Romansh—reflecting a long-standing tradition of multilingualism and cultural pluralism. Swiss national identity nonetheless remains fairly cohesive, rooted in a shared historical background, common values such as federalism and direct democracy, and Alpine symbolism. Swiss nationhood transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a conventional nation state.
The country originates from the Old Swiss Confederacy established in the Late Middle Ages as a defensive and commercial alliance; the Federal Charter of 1291 is considered the country's founding document. The confederation steadily expanded and consolidated despite external threats and internal political and religious strife. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The confederation was among the first and few republics of the early modern period, and the only one besides San Marino to survive the Napoleonic Wars. Switzerland remained a network of self-governing states until 1798, when revolutionary France invaded and imposed the centralist Helvetic Republic. Napoleon abolished the republic in 1803 and reinstated a confederation. Following the Napoleonic Wars, Switzerland restored its pre-revolutionary system, but by 1830 faced growing division and conflict between liberal and conservative movements; this culminated in a new constitution in 1848 that established the current federal system and enshrined principles such as individual rights, separation of powers, and parliamentary bicameralism.
Switzerland has maintained a policy of armed neutrality since the 16th century and has not fought an international war since 1815. It joined the Council of Europe in 1964 and the United Nations (UN) in 2002, pursuing an active foreign policy that includes frequent involvement in peace building and global governance. Switzerland is the birthplace of the Red Cross and hosts the headquarters or offices of most major international institutions, including the WTO, the WHO, the ILO, FIFA, the WEF, and the UN. It is a founding member of the European Free Trade Association (EFTA) and participates in the European single market and the Schengen Area. Switzerland is among the world's most developed countries, with the highest nominal wealth per adult and the eighth-highest gross domestic product (GDP) per capita. It performs highly on several international metrics, including economic competitiveness, democratic governance, and press freedom. Zurich, Geneva and Basel rank among the highest in quality of life, albeit with some of the highest costs of living. Switzerland has a longstanding banking and financial sector, advanced pharmaceutical and biotechnology industries, and a strong tradition of watchmaking, precision engineering, and technology. It is known for its chocolate and cheese production, well-developed tourism industry, and growing startup sector. (Full article...)
The Swabian War of 1499 (Alemannic German: Schwoobechrieg; spelling depending on dialect), called Schwabenkrieg or Schweizerkrieg ("Swiss War") in Germany and Engadiner Krieg ("War of the Engadin") in Austria, was the last major armed conflict between the Old Swiss Confederacy and the House of Habsburg. What had begun as a local conflict over the control of the Val Müstair and the Umbrail Pass in the Grisons soon got out of hand when both parties called upon their allies for help; the Habsburgs demanding the support of the Swabian League, while the Federation of the Three Leagues of the Grisons turned to the Swiss Eidgenossenschaft. Hostilities quickly spread from the Grisons through the Rhine valley to Lake Constance and even to the Sundgau in southern Alsace, the westernmost part of the Habsburg region of Further Austria.
Many battles were fought from January to July 1499, and in all but a few minor skirmishes, the experienced Swiss soldiers defeated the Swabian and Habsburg armies. After their victories in the Burgundian Wars, the Swiss had battle-tested troops and commanders. On the Swabian side, distrust between the knights and their foot soldiers, disagreements amongst the military leadership, and a general reluctance to fight a war that even the Swabian counts considered to be more in the interests of the powerful Habsburgs than in the interest of the Holy Roman Empire proved fatal handicaps. When his military high commander fell in the Battle of Dornach, where the Swiss won a final decisive victory, Emperor Maximilian I had no choice but to agree to a peace treaty signed on September 22, 1499, in Basel. The treaty granted the Confederacy far-reaching independence from the empire. Although the Eidgenossenschaft officially remained a part of the empire until the Treaty of Westphalia in 1648, the peace of Basel exempted it from the imperial jurisdiction and imperial taxes and thus de facto acknowledged it as a separate political entity.

Bobsleigh or bobsled is a winter sport in which individual athletes or teams of two to four athletes make timed speed runs down narrow, twisting, banked, iced tracks in a gravity-powered sleigh. International bobsleigh competitions are governed by the International Bobsleigh and Skeleton Federation (formerly the FIBT).
The first bobsleds were built in the late 19th century in St. Moritz, Switzerland, by wealthy tourists from Victorian Britain who were staying at the Palace Hotel owned by Caspar Badrutt. The early sleds were adapted from boys' delivery sleds and toboggans. These eventually evolved into bobsleighs, luges and skeletons. Initially the tourists would race their hand-built contraptions down the narrow streets of St. Moritz; however, as collisions increased, growing opposition from St. Moritz residents led to bobsledding being eventually banned from public highways. The Cresta Run remains the oldest in the world and is the home of the St. Moritz Tobogganing Club. It has hosted two Olympic Winter Games and is still in use. (Full article...)
Leonhard Euler (/ˈɔɪlər/ OY-lər; 15 April 1707 – 18 September 1783) was a Swiss polymath who was active as a mathematician, physicist, astronomer, logician, geographer, music theorist and engineer. He founded the studies of graph theory and topology and made influential discoveries in many other branches of mathematics, such as analytic number theory, complex analysis, and infinitesimal calculus. He also introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. He is known for his work in mechanics, fluid dynamics, optics, astronomy, and music theory. Euler has been called a "universal genius" who "was fully equipped with almost unlimited powers of imagination, intellectual gifts and extraordinary memory". He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia.
Euler is credited for popularizing the Greek letter (lowercase pi) to denote the ratio of a circle's circumference to its diameter, as well as first using the notation for the value of a function, the letter to express the imaginary unit , the Greek letter (capital sigma) to express summations, the Greek letter (capital delta) for finite differences, and lowercase letters to represent the sides of a triangle while representing the angles as capital letters. He gave the current definition of the constant , the base of the natural logarithm, now known as Euler's number. Euler made contributions to applied mathematics and engineering, such as his study of ships helping navigation, his three volumes on optics, which contributed to the design of microscopes and telescopes, and his studies of beam bending and column critical loads.
