A team of scientists has employed a theorem dating back 350 years, commonly used for describing physical systems, to explore novel aspects of light. By considering light intensity as a surrogate for physical mass, the researchers succeeded in representing light within a framework where existing mechanical equations hold. This methodology revealed an immediate relationship between the level of non-quantum entanglement and the degree of polarization in a light wave. Such discoveries could make the complex properties of optical and quantum systems easier to grasp through basic light intensity metrics.
Scholars at the Stevens Institute of Technology leveraged a theorem initially intended to elucidate the mechanics of pendulums and celestial bodies, to unearth new attributes of light waves.
Since the 17th-century discussions between luminaries Isaac Newton and Christiaan Huygens regarding the fundamental nature of light, the scientific community has been wrestling with the dualistic nature of light as both a wave and a particle. Current research from the Stevens Institute of Technology presents a fresh linkage between these two views, utilizing a 350-year-old mechanical theorem, generally used for explaining the motion of sizable physical entities like pendulums and planets, to shed light on the intricate behaviors of light waves.

Discovering Links Among Various Light Attributes
The study, spearheaded by Xiaofeng Qian, an assistant professor of physics at Stevens, and published in the Physical Review Research journal on August 17, establishes for the first time a direct and complementary link between a light wave’s degree of non-quantum entanglement and its degree of polarization. As one aspect increases, the other diminishes, allowing the extent of entanglement to be directly deduced from the polarization level and vice versa. This implies that more elusive optical characteristics, including amplitudes, phases, and correlations—potentially even those within quantum wave systems—can be inferred from a more readily measurable quantity: light intensity.
Mechanical Theorem’s Novel Application to Light
Qian’s research group applied Huygens’ mechanical theorem, articulated initially in a 1673 publication about pendulums, which outlines how the energy required for an object’s rotation varies with its mass and the axis of rotation. “The theorem has been established for understanding physical systems ranging from timekeeping devices to prosthetic limbs,” Qian stated. “We demonstrated that it can also provide fresh perspectives on the operations of light.”
The question arises: How can a theorem concerning mass and rotational momentum be utilized for light, which lacks mass? The team reasoned that the intensity of light could function as an analog for the mass of a physical object. They then projected these calculations onto a coordinate system interpretable via Huygens’ mechanical theorem. “We essentially devised a method to transpose an optical system into a mechanical one, which we could then describe through well-founded physical equations,” Qian elaborated.
Upon conceptualizing a light wave within a mechanical system, new correlations between the wave’s characteristics became instantly visible—most notably, the direct relationship between entanglement and polarization.
“These were connections that had never been demonstrated before but become lucid once you adapt light’s attributes onto a mechanical framework,” Qian asserted. “One can now measure distances between the ‘center of mass’ and other mechanical points, elucidating how various light properties are interrelated.”
The demystification of these relationships holds significant practical potential, facilitating the derivation of nuanced and challenging-to-measure attributes of optical and possibly even quantum systems from simpler, more direct light intensity measurements, Qian further expounded. More tentatively, the findings raise the prospect of employing mechanical systems to simulate and thereby enhance our understanding of the perplexing and intricate behaviors of quantum wave systems.
“In summary, this inaugural study signifies that the application of mechanical principles can offer a novel lens through which to view optical systems,” Qian concluded. “At its core, this research aims to streamline our comprehension of the universe by highlighting the inherent interconnectedness between ostensibly disparate physical laws.”

Impressive how they can draw a parallel between mechanical systems and light properties. It’s like connecting the dots in a completely new way.
Mind-blowing how they connected classical and quantum concepts. Def gonna keep an eye on Stevens Institute’s future research.
So basically, this means we can use old math to explain new physics? Thats kinda cool if you ask me.
This Qian guy and his team are onto something big. Kudos to them. What’s next tho? Quantum mechanics?
um, can someone break this down for me? Its a lot to take in but sounds important.
Feels like this could be a real breakthrough. Wonder what practical applications could come out of it.
Wow, never thought a 350-yr-old theorem could help us understand something as complex as light. This is game-changing!
