Switzerland, officially the Swiss Confederation, is a landlocked country located in west-central Europe. It is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is geographically divided among the Swiss Plateau, the Alps and the Jura; the Alps occupy the greater part of the territory, whereas most of the country's nearly 9 million people are concentrated on the plateau, which hosts its largest cities and economic centres, including Zurich, Geneva, and Lausanne.
Switzerland is a federal republic composed of 26 cantons, with federal authorities based in Bern. It has four main linguistic and cultural regions: German, French, Italian and Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared values such as federalism and direct democracy, and Alpine symbolism. Swiss identity transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a nation state.
Switzerland 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 recognised 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.

Nico Hischier (born 4 January 1999) is a Swiss professional ice hockey centre and captain of the New Jersey Devils of the National Hockey League (NHL). Hischier made his professional debut in his native Switzerland in 2015, spending time both in the top-tier National League A (NLA) and the second-tier National League B. He moved to North America for the 2016–17 season to play major junior hockey for the Halifax Mooseheads of the Quebec Major Junior Hockey League (QMJHL) in hopes of furthering his hockey career; in his first season in the QMJHL, he was named rookie of the year, along with the award for best rookie in the Canadian Hockey League (CHL), the governing body for major junior hockey in Canada. Internationally Hischier has represented Switzerland at several junior tournaments, including two World Junior Championships. Regarded as a strong two-way forward and a top prospect for the 2017 NHL entry draft, Hischier was selected first overall by the Devils, the first time a Swiss player was selected first overall, and made his NHL debut in 2017. He was named captain of the Devils in 2021. (Full article...)
The Gotthard Base Tunnel (GBT; German: Gotthard-Basistunnel, Italian: Galleria di base del San Gottardo, Romansh: Tunnel da basa dal Sogn Gottard) is a railway tunnel through the Alps in Switzerland. It opened in June 2016 and full service began the following December. With a route length of 57.09 km (35.47 mi), it is the world's longest railway and deepest traffic tunnel and the first flat, low-level route through the Alps. Located at the heart of the Gotthard axis, it is the third tunnel to connect the cantons of Uri and Ticino, after the Gotthard Tunnel and the Gotthard Road Tunnel.
The GBT consists of a large complex with, at its core, two single-track tunnels connecting Erstfeld (Uri) with Bodio (Ticino) and passing below Sedrun (Grisons). It is part of the New Railway Link through the Alps (NRLA) project, which also includes the Ceneri Base Tunnel further south (opened on 3 September 2020) and the Lötschberg Base Tunnel on the other main north–south axis. It is referred to as a "base tunnel" since it bypasses most of the existing vertex line, the Gotthard railway line, a winding mountain route opened in 1882 across the Saint-Gotthard Massif, which was operating at its capacity before the opening of the GBT. The new base tunnel establishes a direct route usable by high-speed rail and heavy freight trains. (Full article...)
Leonhard Euler (/ˈɔɪlər/ OY-lər; German: [ˈleːɔnhaʁt ˈɔʏlɐ] ⓘ, Swiss Standard German: [ˈɔʏlər]; 15 April 1707 – 18 September 1783) was a Swiss polymath who was active as a mathematician, physicist, astronomer, logician, geographer, 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 which helped navigation, his three volumes on optics contributed to the design of microscopes and telescopes, and he studied the bending of beams and the critical load of columns.
