The Great Gatsby: Twenty Years Later

The Great Gatsby: Twenty Years Later I had only a mild, foggy memory of reading The Great Gatsby by F. Scott Fitzgerald more than twenty years ago, and of not being particularly impressed by it at the time. Last week, I watched Baz Luhrmann’s film adaptation, and it came as a complete surprise—I realized I didn’t remember a single thing about the story. The film rekindled my interest, and I decided to give the novel another try, as it’s very likely that I—or rather, my younger self—was not able to fully appreciate it back then. As for the movie, I can only recommend it. In an era dominated by reruns, sequels, and the like, it serves as a reminder of how rewarding a truly good story, well told through cinema, can be—and how well spent that time is (something I had almost forgotten).

In Memory of Professor John Hull

In Memory of Professor John Hull It was with a surprisingly sad and melancholic feeling that I read the news of Professor John Hull’s passing. Not because he was ever my professor, nor because I had the privilege of knowing him personally, but because he has been part of my life for a long time—mainly through his published textbooks, especially Options, Futures, and Other Derivatives (7th Edition). That book enabled me to understand, both conceptually and from a mathematical point of view, what options are and how they can be valued. In doing so, it allowed me to develop my MSc thesis, “Capital Structure Active Management – A Contingent Claim Approach.” For all of this, I offer my heartfelt thanks to Professor Hull, along with my deepest and most sincere condolences to his family.

IA y matemáticas: cuando la máquina acelera la ciencia

IA y matemáticas: cuando la máquina acelera la ciencia https://elpais.com/ciencia/cafe-y-teoremas/2026-01-05/repensando-las-matematicas-en-la-era-de-la-inteligencia-artificial.html “Por ello, la inteligencia artificial multiplica el alcance del experto, pero, en manos del principiante, puede limitarse a amplificar su ruido.” Artículo muy interesante de El País sobre cómo la inteligencia artificial puede ayudar en el desarrollo del conocimiento y de la ciencia, en particular en el ámbito de las matemáticas. En mi opinión, la IA —hasta prueba en contrario— servirá como un asistente (o cien) que realice todas las comprobaciones necesarias y exhaustivas de las demostraciones y teoremas generados por los científicos, acelerando así el proceso científico por un factor de diez. Además, podrá identificar, a partir de grandes volúmenes de datos ruidosos, patrones y conjeturas (extraer señal de datos muy ruidosos) que serían muy difíciles de detectar para un humano o que requerirían muchísimo tiempo. “Del diálogo entre matemáticas e IA podrían nacer tecnologías más transparentes y fiables y una mejor comprensión de cómo razona la máquina. Impulsar el encuentro entre estas dos disciplinas, tanto en el ámbito empresarial como en la investigación básica, es, por tanto, una tarea urgente. Y esta sinergia solo puede prosperar con un apoyo fuerte y sostenido a ambas áreas por separado.”

Why NOAA Matters More Than You Think

The first time I read about NOAA (the National Oceanic and Atmospheric Administration) was in The Fifth Risk by Michael Lewis (see my note with a short review below), which details what was done to the agency during Trump’s first administration. This news doesn’t surprise me at all. There is clearly much more here than meets the eye, and the consequences are significant. Somewhat surprisingly, the impact will be felt across all of American society—but it will hit Trump’s own voter base particularly hard, which never ceases to amaze me. I recommend taking a few minutes to read this NASA article; it provides an excellent perspective on what this all entails, especially in the context of the climate-change reality we are currently living in.
