Featured Article: Fermion

In particle physics, fermions are a group of elementary (or fundamental) particles that are the building blocks of matter. They are named after Enrico Fermi. In the Standard Model, elementary particles are classified as fermions and bosons. Fermions are usually related with matter, whereas bosons are related with fundamental forces (or radiation). Fermions are subdivided into quarks and leptons. Quarks are fermions that couple with a class of bosons known as gluons to form composite particles such as protons and neutrons. Leptons are those fermions that do not undergo coupling with gluons. Electrons are a well-known example of leptons. Everyday matter is composed of the first generation of fermions: two leptons, the electron and electron-neutrino; and two quarks, called Up and Down.

Wisława Szymborska in Kraków, 2009

Maria Wisława Anna Szymborska (July 2, 1923 – February 1, 2012) was a Polish poet, essayist, translator, and recipient of the 1996 Nobel Prize in Literature. Born in Prowent (now part of Kórnik in west-central Poland), she resided in Kraków until the end of her life. In Poland, Szymborska's books have reached sales rivaling prominent prose authors, though she wrote in a poem, "Some Like Poetry" ("Niektórzy lubią poezję"), that "perhaps" two in a thousand people like poetry. She was already well-known in Poland, but became better known internationally after receiving the Nobel Prize.
