I don't know if Jordi Oriol, one of the most original creators of Catalan theatre, knows the work of the linguist and semiologist Ferdinand de Saussure, but his theatre in general and in particular L'últim àtom make me think so, because he uses linguistic games that alter the meaning of signs and words, illustrating the principle of linearity of the signifier and achieving surprising and humorous results. This is evident, for example, in the pronunciation (the speech) of the title of the show if we connect the two words or, more naively, if we consider the presumed and unknown actress Lara Segur, with phonetics that recall the name and surname of another well-known actress, who will not appear on stage and will be replaced by a supposed director: the actor Rubèn Ametllé. There is much more on the old green blackboard of the language teacher Mia Esteve, who plays with signifiers and signifieds and who replicates the mathematical formulas of professor Joan Carreras on another blackboard, where, talking about quantum physics and Schrödinger's cat, she posits the principle of observation as an international virus that threatens humanity. The professor and teacher are separated parents of a daughter who disappeared ten years ago, whose anniversary is approaching. She is joined by a Spanish-speaking army general, a priest, a mother in a wheelchair, a police inspector, the mother's lover, a theatre student, and a president who doesn't arrive... characters who inhabit a well-posed story but not so well resolved in the construction of a dramaturgy that is a victim of the same flexible and intuitive structure with which it is presented to us.

What do science and language have in common today? Playwright and director Jordi Oriol has no doubt: the uncertainty principle. "Scientists have reached a point where they need to know more, but they can't. Science has begun to speak in metaphors, mathematics is about statistics and probabilities. We have gone from Shakespearean to be or not to be to to be and not to be at the same time," says Oriol. Faced with this reality, the creator has built a show that unites the two worlds to make their connections evident. Titled The Last Atom (which can also be read as "L'ultimàtum", in one of the creator's fun linguistic winks), the production stars Joan Carreras and Mia Esteve and will be performed from May 29 to June 21 at the Teatre Goya.

March is dance time. The Fifteenth Metropolitan Dance Festival is a festival promoted by Barcelona City Council, in which up to twelve municipalities in the metropolitan area collaborate to spread dance far and wide. The eighth edition has arrived with more than 100 performances in theaters, squares, and streets, in addition to other parallel activities scheduled from March 14 to 30. The National Theater (TNC) is collaborating with two interesting and very diverse proposals.
