Gustaf Ullman — Perspectives on Physics and Philosophy

Lek, Genialitet och AI Att leka sig fram till genialitet Lek är något vi ofta förknippar med barndomen, men det kan vara minst lika betydelsefullt för oss vuxna. Detta har blivit tydligt för mig när jag studerat musikaliska underbarn som Wolfgang Amadeus Mozart och Emily Bear. Båda började i tidig ålder, inte för att de tvingades, utan för att musiken för dem blev en naturlig "leksak". Mozart kunde som barn sitta vid pianot i timmar, ungefär som barn ibland försjunker i att bygga med Lego, utan tvång eller krav. Emily Bear komponerade redan som mycket ung och fick som 10-åring en högskoleutbildning i filmmusik – hon sökte sig till musiken på eget initiativ. Dessa ovanliga och inspirerande exempel visar hur lekfullhet kan bestå ända in i vuxen ålder. Mozart, Emily Bear och även Felix Mendelssohn lekte fram sina kompositioner med kontrapunkt, harmoniska överraskningar och rytmiska finesser. Denna lekfullhet kan ibland tolk...

Norwood Russell Hanson and the Art of Hearing: Seeing Music as Inner Vision One of Norwood Russell Hanson’s central ideas is that observation is theory-laden—what we perceive depends on what we know. This insight extends beyond science and philosophy into the realm of music, where perception often requires training and understanding. Consider a fugue. To the untrained ear, it might sound like a complex but indistinct flow of notes. However, for someone with a trained ear, it is an intricate interplay of counterpoint, modulation, and thematic development. The same is true for recognizing syncope or modulation; these are not just elements of sound but concepts that must be "seen" with the mind. Music as a Visual Experience Interestingly, I choose the word "see" rather than "hear" when describing this experience, because I believe it mirrors the same inner vision we use in mathematics or other abstract disciplines. Just as a mathematician "sees...

Are Stars a Form of Life? A Metabolic Perspective One of the defining characteristics of life, as commonly understood in biological terms, is metabolism. Metabolism refers to the set of chemical processes that allow an entity to sustain itself, grow, and interact with its environment. In this context, the question arises: could stars, with their remarkable nuclear processes, be considered a form of life? The Metabolism of Stars Stars are born from vast clouds of gas and dust, primarily hydrogen. As they form, the immense pressure and temperature in their cores initiate nuclear fusion—a process where hydrogen atoms combine to form helium. This phase, known as the main sequence, dominates a star’s life and is analogous, in some sense, to an organism consuming a primary energy source to maintain itself. As stars exhaust their hydrogen, they begin to "metabolize" helium, producing heavier elements such as carbon, nitrogen, and oxygen. These elements are essential for the ...

Reflections on The Mission : A Review Some time ago, I wrote about the soundtrack to The Mission , expressing my admiration for its haunting beauty. When I watched the film, I found it to be deeply moving, a work that touched me on a profound emotional and spiritual level. At its core, the film carries strong influences from Christian anarchism, particularly its unwavering commitment to pacifism. However, like many works with a strong ideological bent, it is not without its flaws. The film is, fundamentally, a portrayal of Christian missionary work. In this respect, it mirrors the historical errors of many Christian missionaries by underestimating the wisdom and spirituality already present in indigenous cultures. The narrative frames the Christian mission in South America as a largely positive force, which, in the eyes of modern viewers, may feel deeply problematic. This critique is not directed at the spiritual core of Christianity, which emphasizes love and humility, but at hist...

The Music of the Spheres: A Journey Through Harmony and Elegance The Music of the Spheres is perhaps the best piece I have created that combines physics, art and music. This work, available on YouTube, visualizes the pattern formed by drawing a line between Earth and Venus over the course of five Earth years. This period corresponds to eight Venusian years. These numbers—8 and 5—are Fibonacci numbers, and together they create a beautiful five-petaled flower pattern. Having studied physics at an advanced level, my intention with this piece was to reveal the profound elegance inherent in physics, an elegance that is often inaccessible to most. The work draws inspiration from Johannes Kepler and Pythagoras, two towering figures in the history of science and art. Pythagoras not only discovered the mathematical relationships underlying our musical scale but also influenced the concept of harmony that links mathematics, music, and the cosmos. Kepler, centuries later, sought the harmony ...

In the philosophy of science, names like Popper and Kuhn are well-known. We occasionally hear of figures like Feyerabend and Lakatos as well, yet Norwood Russell Hanson is rarely mentioned. Kuhn was inspired by his philosophy, but actually I like the original better. Hanson was influenced by Wittgenstein’s later philosophy, particularly the idea that meaning and perception are shaped by our conceptual frameworks and language. From this, Hanson developed his notion of “theory-ladenness,” arguing that scientific observation is never purely objective but always influenced by prior knowledge and theoretical commitments. This view, foundational to Hanson’s work, highlights that in science, what we see depends on how we understand—a perspective that also influenced thinkers like Kuhn. Norwood Russell Hanson argued that observation in science is never purely objective; it’s always influenced by prior theories, beliefs, and expectations—a concept he called “theory-ladenness.” He believed that ...
