Postgrad Chronicles #7: Diving into Philosophy as a Physics Researcher

Lately, I’ve found myself caught between two seemingly opposite worlds: the rigorous precision of physics research and the abstract, often unsettling inquiries of philosophy. As my work in physics has grown more specialized, I’ve felt an increasing pull towards the existentialist and nihilistic musings of Nietzsche, Camus, Schopenhauer, and Sartre. Perhaps it’s the long hours spent deciphering equations that makes me crave the broader, messier questions of existence. Or maybe it’s the realization that, at the heart of it all, physics and philosophy are not so different after all.

The Search for Meaning in a Universe of Equations

In physics, we seek fundamental truths—universal laws that govern reality, mathematical frameworks that predict behavior with precision. But reading philosophy, especially existentialism and pessimism, challenges the idea that there is an inherent “truth” to uncover at all. Schopenhauer’s world of suffering, Camus’ absurdism, and Nietzsche’s will to power make me wonder: Is science just another human attempt to impose structure on an indifferent universe?

Physics research often feels like Sisyphus rolling his boulder uphill—an endless cycle of hypothesis, experimentation, and revision. Camus, of course, tells us to imagine Sisyphus happy. But is the physicist happy in this relentless search, knowing that every answer leads to a dozen more questions? If there is no ultimate meaning, why do we persist? The best answer I’ve found is one of commitment—to the process itself, to curiosity, and to the simple joy of uncovering patterns in nature.

At times, I find myself oscillating between awe and frustration. The sheer elegance of mathematical descriptions of the universe is enough to make one believe in some deeper underlying order. And yet, as Nietzsche would argue, perhaps this order is simply an illusion, a construct of the human mind attempting to make sense of an inherently chaotic existence. The beauty of physics, then, is not in the discovery of some preordained truth but in our creative capacity to model, understand, and ultimately interpret the world on our own terms.

Determinism, Free Will, and the Limits of Knowledge

Reading Nietzsche and Sartre has made me question the deterministic foundations of physics. Classical mechanics suggests a world of predictable outcomes, but quantum mechanics throws in unpredictability at a fundamental level. And yet, does randomness equate to free will? Or is it just another layer of chaos?

Sartre would argue that we are condemned to be free, that meaning is ours to create. But as a physicist, it’s difficult to escape the sense that we are bound by initial conditions, that everything—even our thoughts—might just be the consequence of particles following their predetermined paths. Wrestling with these questions doesn’t change the math I do on a daily basis, but it certainly changes how I view my place in the cosmos.

Perhaps the real challenge lies not in reconciling these contradictions but in learning to live with them. After all, just as the uncertainty principle limits how much we can know about a particle’s state, perhaps there are similar epistemic limits to our understanding of reality itself. If Sartre is right that meaning must be created, then maybe the physicist’s work is precisely that—an act of creation, of carving out a sense of order within the vast, uncaring void.

Embracing the Absurd

Camus' idea of the absurd—the tension between our desire for meaning and the universe’s silence—hits particularly hard in research. There is something absurd about dedicating years to solving a problem that, in the grand cosmic scale, might not matter at all. But Camus would say that’s precisely the point: The absurd is not something to be defeated but embraced. And in a way, that’s what physics is all about—embracing the absurd, diving into the unknown despite knowing that we might never find absolute answers.

Yet, perhaps this is where the true joy of research lies. The process itself, with its breakthroughs and failures, its dead ends and eureka moments, is where the meaning is found. The absurdist physicist does not seek ultimate truth but revels in the act of questioning itself. And in doing so, we give ourselves the freedom to explore without the burden of needing a final answer.

Finding Balance Between Physics and Philosophy

While philosophy has made me question many things, it has also provided perspective. Physics gives me tools to understand the material world; philosophy reminds me that understanding is never complete. One is the pursuit of precision, the other of wisdom. Both are necessary.

This duality is not an easy one to navigate. There are days when I am utterly consumed by the rigor of research, lost in equations and simulations. Then there are days when I put the books down and simply ponder—what does it all mean? I used to see these moments of doubt as a hindrance, a distraction from the work that needed to be done. But now, I see them as essential. They are reminders that science is not just about results; it is about the pursuit itself.

So, I keep reading. I keep questioning. And I keep doing physics, even if the deeper I go, the more I realize how little I truly know. Maybe that’s the best place to be—caught between the rigor of equations and the openness of existential doubt. It’s not a contradiction; it’s a balance. And for now, I’m okay with that.

If there’s one thing I’ve learned from both physics and philosophy, it’s that the most meaningful pursuits are often the ones that have no clear end. In that sense, maybe we are all like Sisyphus—pushing forward, knowing that the summit will always be just out of reach, but finding purpose in the climb itself.
