This article marks the conclusion of the 'Café y teoremas' section in El País, which dedicated the last ten years to bringing rigorous and contextual mathematics to a broader audience. Initiated as a collaboration with the Institute of Mathematical Sciences (ICMAT), the section aimed to fill a gap in mainstream media's treatment of mathematics, often sidelined in favor of more popular scientific topics. The enthusiasm from El País, particularly from Patricia Fernández de Lis, helped launch the series with an inaugural article highlighting the work of mathematician Ramanujan.

The title of the section, 'Café y teoremas,' derives from a well-known quote by Alfred Rényi, a prominent mathematician of the 20th century, suggesting that mathematicians transform coffee into theorems. This reflects the dynamic and human aspect of mathematics, emphasizing that the discipline is not just about abstract concepts but involves creativity and deep thinking fueled by daily habits such as enjoying coffee. The article notes that this humanistic approach was a core philosophy throughout the series, allowing complex mathematical ideas to be showcased in an engaging and accessible manner.

As the section bids farewell, it does so with gratitude for the past decade, celebrating its role in bringing mathematical discourse into the public realm and encouraging readers of all backgrounds to appreciate the beauty and relevance of mathematics in everyday life. The legacy of 'Café y teoremas' will likely inspire future efforts to continue bridging the gap between mathematics and the general public, ensuring that these critical insights remain part of broader societal conversations.
