The Subatomic Symphony of Life
By P. Sineesh
Despite its oddness, quantum mechanics has been proven through experiments and now powers modern life, from nuclear energy and MRI machines to computers and smartphones. The year 2025 marks the centennial of quantum mechanics, one of the most transformative advances in modern science. Quantum mechanics is no longer just about tiny particles in physics labs. Scientists are now using it to study life itself. With tools like Raman spectroscopy, they can examine viruses and cells at extremely small scales.
The great Master of Mathematics, Euclid, through his Elements, did more than organize geometry. He built the very architecture of logical reasoning, the scaffold on which modern science would stand. Two millennia later, William Rowan Hamilton revealed a deep unity between light and motion, unsettling classical physics and foreshadowing quantum theory. Then in 1926, Max Born transformed certainty into probability, declaring that the laws of nature speak not in absolutes, but in likelihood.
Euclid gave us certainty. Hamilton gave us structure. Born gave us probability. Together, they shaped the language of the universe.
Galileo famously said, “Mathematics is the language with which God has written the universe”. In the strange world of the very small, reality doesn’t follow common sense, it follows equations. At its deepest level, the universe isn’t just described by math, it runs on it!
Max Planck introduced the idea that energy comes in tiny packets just to fix a stubborn problem in his equations, thinking it was only a mathematical trick. He never imagined those ‘quanta’ were real pieces of nature. Albert Einstein, the most brilliant scientist of the last century took the idea seriously and turned a humble calculation into a revolution in how we understand the universe.
God does not play dice with the universe!
In 1926, Albert Einstein wrote to Max Born, a founder of Quantum Mechanics: “God does not play dice with the universe.” Unlike classical physics, where actions lead to predictable results, quantum mechanics suggested that outcomes are uncertain and probabilistic, something that troubled Einstein. The debate even rippled beyond science, noted by Vladimir Lenin and later described by Christopher Caudwell in The Crisis in Physics. Despite its oddness, quantum mechanics has been proven through experiments and now powers modern life, from nuclear energy and MRI machines to computers and smartphones.
The year 2025 marks the centennial of quantum mechanics, one of the most transformative advances in modern science. The revolution began with Heisenberg’s 1925 paper on matrix mechanics and continued with Schrödinger’s formulation of the wave equation in 1926.
Erwin Schrödinger’s famous cat paradox illustrates quantum superposition, where a system can exist in multiple states at once. In this probabilistic realm, particles follow multiple possible paths, yet these quantum principles underpin much of modern technology.
The Sun shines because of a quantum effect called tunnelling, which lets tiny particles pass through barriers they normally couldn’t. This makes nuclear fusion possible, turning matter into energy and producing sunlight.
From Particles to the Pulse of Life
Quantum mechanics is no longer just about tiny particles in physics labs. Scientists are now using it to study life itself. With tools like Raman spectroscopy, they can examine viruses and cells at extremely small scales.
The roots of quantum biology are often traced to 1944, when Erwin Schrödinger published his groundbreaking book What Is Life? In it, he asked a bold question, “Could the strange laws of quantum physics explain the mystery of life itself?” But Schrödinger wasn’t the first to think this way. A year earlier, the German physicist Pascual Jordan had already stepped into this territory with his book Physics and the Secret of Organic Life. In it, Jordan posed a provocative idea, “Are the laws of atomic and quantum physics essential to life?”
Scientists in quantum biology study phenomena like quantum tunnelling, coherence, and entanglement, weird effects usually seen in tiny particles, that quietly help life.
Quantum physics shows that everything, including our bodies, is made of energy vibrating at different frequencies. Each cell and tissue has its own natural vibration that keeps it healthy. When these vibrations are balanced, the body functions well. When they’re out of balance, the body struggles to build new cells, break down old ones, and transform energy and leading to illness.
Many biological processes like photosynthesis, breathing, and vision rely on quantum effects at the molecular level.
For example: In chickens, retinal molecules in the eye are stimulated by sunlight. This light exposure alters the shape of retinal, triggering protein activation through quantum phenomena. The resulting signals travel to the brain, where the hypothalamic pituitary axis is activated, leading to the release of follicle stimulating hormone (FSH). As a result, egg production begins.
When the Heart Speaks in Quantum Waves
The heart isn’t just a pump; it’s a mini brain. Housing 40,000 neurons, it can sense, process, and store information independently, generating the body’s strongest electromagnetic field, detectable several feet away. Think of it as a command centre, orchestrating harmony in your body.
Millions of heart cells beat in perfect synchrony, guided by principles that echo quantum ideas, coherence (unity) and resonance (adaptive rhythm). This heartbeat harmony is mirrored in heart rate variability, a key indicator of health.
We are not just brains; we are a brain heart team. The gut, our second brain fuels intuition, the brain handles rational thinking, and the heart synchronizes the two, enabling smooth body mind communication. Positive emotions like calm, joy, and gratitude create coherent heart rhythms, aligning the brain, nervous system, and hormones for clarity and wellbeing. Scientists are investigating how the gut communicates with the brain through the vagus nerve, new theories specifically called quantum tunnelling and molecular quantum communication.
Cells Meet Quantum Physics
Quantum tunnelling is the ultimate particle hack. Instead of climbing over barriers, tiny particles like electrons and protons just phase through them. And it’s not just physics labs; this happens inside our bodies too. Electrons in our cells pull off these quantum stunts to supercharge enzymes, accelerate chemical reactions, and power mitochondria with uncanny efficiency. In other words, life itself exploits quantum shortcuts.
Enzymes, the body’s chemical ‘boosters’ use tunnelling to move particles quickly, speeding up reactions needed for life. Our body’s power plant, mitochondria help electrons flow efficiently to produce energy currency – the molecule that powers muscles, the brain, and other high energy tissues.
The conversion of ergocalciferol (Provitamin D) to calciferol (Vitamin D) happens when UV light hits the molecule and causes a chemical change. In some steps, tiny particles like electrons or hydrogen atoms move through barriers in a way that classical chemistry can’t explain. This is called Quantum Tunnelling.
Quantum Tunnelling may also aid DNA repair and occasionally create small changes that drive genetic diversity.
Albert Einstein called it “spooky action at a distance”
Albert Einstein famously called quantum entanglement “spooky action at a distance”. In this phenomenon, measuring one particle instantly affects its entangled partner, regardless of the distance between them. For example, it’s as if a single entity could appear in two different places at the same time. Einstein found this deeply puzzling because it seemed to violate the speed of light limit and suggested that particles do not have definite properties until they are observed.
We can measure the brain’s signals, yet we still don’t know how they become thoughts. Roger Penrose and Stuart Hameroff proposed a bold idea: consciousness may begin deep inside brain cells, where quantum physics quietly shapes awareness.
Every year, millions of birds fly far distances. A special protein in their eyes, called cryptochrome, may help them sense the Earth’s magnetic field. Tiny particles in the protein react to light and the magnetic field, and quantum entanglement may be involved, helping birds know which way to fly.
Invisible Bloom of Quantum Dawn
Human vision begins at the quantum level, where individual photons are absorbed by light sensitive molecules in the retina, triggering biochemical reactions that allow us to see, revealing the probabilistic nature of the quantum world.
Quantum Symphony of Ear, Mind, and Heart
Inspired by ideas like those of Michio Kaku, some researchers explored whether hearing, thinking, and feeling are deeply connected in an ‘ear brain heart’ system. The ear turns sound into signals, the brain interprets them, and the heart reflects our emotional response. While a few scientists, including Roger Penrose and Stuart Hameroff, suggested quantum effects might influence brain function, this idea remains speculative. More research is needed to confirm any quantum role.
The Quantum Pulse of Life inside Our Biochemical Factory
Quantum mechanics powers the liver. Every oxidation, reduction, hydrolysis, and conjugation reaction is choreographed at the quantum level. Electrons dance, bonds break and form, and enzymes accelerate reactions with near perfect efficiency. Without quantum effects, detoxification stalls, drug metabolism grinds to a halt, and the liver’s vital role in energy production and protein synthesis collapses.
Redefining Beta Cells: A New Paradigm
Researchers identified evidence that delicate quantum phenomena, such as molecular vibrations and quantum tunnelling, may influence enzymatic activity, protein interactions, and the regulation of insulin and glucose within the body.
Quantum Approaches in Modern Medicine
Many modern medical treatments and imaging tools rely on principles of quantum physics. Lasers, which are made possible by quantum mechanics, are widely used in eye care and skin treatments. Magnetic resonance imaging (MRI) depends on quantum physics to understand how atoms behave in strong magnetic fields, and its development was made possible by superconductivity, a unique quantum property of matter. In addition, cancer cells can be detected using particle physics through PET (Positron Emission Tomography) scans. Together, these technologies show how quantum physics already plays an important role in everyday medical care.
Quantum Driven Drug Delivery
Quantum nanotechnology is advancing drug delivery by using engineered nanoparticles to target specific cells, improving efficacy while reducing side effects. Through quantum effects, these systems enable controlled, stimulus-responsive drug release, while quantum dots enhance imaging and diagnostics paving the way for more precise and personalized treatments.
Sculpting Reality in Qubits New Era of Computation
In 2019, Google marked a historic leap in technology by announcing ‘quantum supremacy’, revealing the boundless potential of quantum computing.
Quantum computing is poised to transform medicine by solving problems too complex for today’s most powerful machines. Unlike classical computers that use 0s and 1s, quantum systems use qubits that can exist in multiple states at once, allowing them to explore many possibilities simultaneously.
For the pharmaceutical industry, this could mean quicker drug discovery, better prediction of how drugs interact with the body, smarter clinical trials, and lower failure rates, a major breakthrough in an industry where over 90% of drug candidates fail. Pharmaceutical companies are already exploring quantum computing partnerships, although challenges like cost and technical limits remain. Quantum computing could dramatically accelerate drug discovery, enable more personalized treatments, reduce clinical trial failures, and help the world respond faster to emerging diseases in the decades ahead.
As Niels Bohr, a founding figure of quantum mechanics, famously said, “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet”.
