Dr. Sinha Reignites Debate on the Physical Nature of Light at IIT Kanpur
India PR DistributionNew Delhi [India], August 21: During a scientific seminar organised by the Department of Physics, Indian Institute of Technology Kanpur (IIT Kanpur) on the 18th August, Dr. Dhiraj Sinha, a faculty member at Plaksha University, delivered a lecture titled 'Emergence of Einstein's Photons from Maxwell's Fields". His talk was based on a recent article he published in Annals of Physics (Vol. 473, 169893, 2025). Dr. Sinha spoke at length on how the particle nature of light, defined by photons, is deeply rooted in classical electromagnetic fields expressed through Maxwell's equations. A subtle message from his discourse was that light's particle nature is an emergent behaviour as a consequence of its interaction with Sinha began with a brief overview of historical context. Light was considered a wave until 1905, when Einstein published his work on the photoelectric effect. Einstein argued that light could be considered as packets of energy or light quanta, which later came to be called photons. According to Einstein, 'When a light ray starting from a point is propagated, the energy is not continuously distributed over an ever-increasing volume, but it consists of a finite number of energy quanta, localized in space which move without being divided and which can be absorbed or emitted only as a whole." Einstein's concept is completely disconnected from the prior work by Maxwell who argued that light is an electromagnetic wave. The current belief is that light has a dual nature: it behaves like a wave in space but exhibits particle-like behaviour during its interaction with the latter part of his lecture, Dr. Sinha focused his attention on his discovery that in light-matter interaction, the magnetic flux of light j, energises an electron of charge e, transferring energy given by e(dj/dt). Its frequency or phasor domain representation is ejw, where w is angular frequency. This term equals h'w, the energy of a photon, where h' is the reduced Planck's constant. He noted that magnetic flux quantisation has been observed in superconducting loops at two-dimensional electron gas systems, which supports his work. He argued that the uniqueness of his work lies in the fact that one starts from classical electromagnetism and derives a key result of quantum mechanics. The theoretical framework offers a bridge between the ideas of two great physicists- Maxwell and Einstein and has deep ploughing consequences regarding our understanding of the nature of discourse quickly evolved into a highly lively and heated debate with the professors from the Department of Physics, IIT Kanpur. The professors with a background in quantum field theory argued that Dr. Sinha's theoretical framework was incomplete as it only focused on magnetic field of light while neglecting its electric field. They also raised the issue of the nature of gauge fixing used in the mathematical analysis. Dr. Sinha countered the argument by showing that the electric and magnetic field of light can be expressed in terms of magnetic vector potential, a physical variable discovered by Franz Neumann in 1845. He further explained the underpinnings of Lorenz gauge in his arguments, which seemed to satisfy the professors. During the next phase of the lecture, deeper disagreements and counter arguments started when Dr. Sinha highlighted the role of magnetic flux quantisation and its central role in understanding the nature of light. The IITK professors felt that using a concept from superconducting loops to make a general argument about the nature of light weakened his theoretical case. One of them argued that magnetic flux quantisation leads to the concept of magnetic monopoles, which have never been found. Dr. Sinha explained that magnetic field always forms closed loops and experimental results on magnetic flux quantisation in superconducting loops have a broader significance, which require more investigation. In the final part, the discussion moved towards the nature of Maxwell's equations in the context of discrete entities. Dr. Sinha suggested that Maxwell's equations are silent about quantisation but are not opposed to it. They hold true for continuous as well as discrete physical quantities. He also pointed out that quantum physicists consider the discrete nature of electrons as classical but view other discrete quantities, like energy and magnetic flux, as quantum, and the framework lacks a coherent and homogenous basis. He concluded by stating that his theoretical framework on the origin of the quantum nature of light in Maxwell's electromagnetic fields offers a radically new perspective on the nature of light. Towards the end, the IIT professors largely agreed that the mathematical framework suggested by Dr. Sinha was coherent. However, they expressed the need for more experimental evidence, which specifically measure the magnetic flux of light in its quantised form. The seminar was attended by the faculty members, students and researchers from a number of different departments viz. physics, chemical engineering and material science. The intense and profound exchange of ideas between the speaker and the faculty members was highly spirited and remarkable. It reignited a lively and intense debate on the physical nature of light, which remains a quintessential mystery of nature.(ADVERTORIAL DISCLAIMER: The above press release has been provided by India PR Distribution.

Civic Eye: The AI Revolution Our Chaotic Cities Desperately Needed
India PR DistributionNew Delhi [India], August 19: No one noticed the man lying on the pavement. Not the cars that zipped past him. Not the shopkeepers nearby. Not even the city's surveillance cameras– until it was too millions living in India's bustling cities, this is a recurring tragedy. Road accidents go undetected. Crimes happen in plain sight with no response. Potholes multiply. Fires spread. All while CCTV cameras dutifully record footage that no one has time–or eyes–to Solutions, a deep tech company born out of India's innovation heartland, is changing this reality. Their latest AI-powered platform, Civic Eye, is turning dumb cameras into city-wide sentinels–capable of detecting, alerting, and even predicting incidents in Surveillance to Smart ActionThe problem isn't that cities lack cameras. India has thousands. The issue is intelligence. Traditional surveillance systems merely observe. Civic Eye acts. Built on cutting-edge AI, computer vision, and real-time data analytics, Civic Eye analyzes live video feeds from existing CCTV networks to detect traffic violations, criminal activities, civic violations, and public safety risks–all without any additional it's a chain-snatching suspect fleeing across streets, a manhole left uncovered, or a vehicle speeding through a red light–Civic Eye spots it, flags it, and notifies the control room and field staff in seconds.'We're not adding more screens. We're making every existing feed smarter," said the Valiance team behind the platform. 'This is the difference between watching and truly seeing what's happening in our cities."A Day in the Life of an OfficerImagine a civic officer on duty. Tasked with managing traffic, responding to emergencies, and ensuring public order, he starts his day with outdated systems, multiple screens, delayed alerts, and no unified visibility. By the time information reaches him, it's often too late. He's left firefighting chaos, not preventing Eye changes this officer receives real-time alerts directly on his dashboard and mobile phone. Incidents like illegal hawking, pothole detection, overcrowding, road accidents, or criminal activities are flagged as they happen. He can query videos by description or license plate, track suspects across multiple zones, and dispatch field teams immediately and even identify crime hotspots over time–all from a single platform. With Civic Eye, the officer is no longer reactive. He's empowered, equipped, and in Intelligence in ActionCivic Eye is more than a monitoring tool–it's a command center of intelligence. During monsoon, for instance, cities struggle with flooding, building collapses, tree falls, and sudden crowd gatherings. Currently, most municipal control rooms still rely heavily on distress calls, ward office reports, or eyewitness Eye eliminates this can automatically flag waterlogging, landslides, traffic congestion, or even potential protests using real-time visual AI. This proactive detection enables timely response, reduces risk, and saves makes the system truly revolutionary is its AI-powered query search–a feature that allows law enforcement to find exactly what they're looking for in minutes. Want to spot all vehicles that jumped a red light between 2-4 PM? Or trace a suspect across cameras using just a partial license plate or clothing pattern? Civic Eye delivers with precision, saving hours of manual footage intelligent video query tool is a breakthrough for overloaded departments–turning days of investigation into moments of Impact. Real Eye has already been deployed in pilot zones across Indian cities, with remarkable results. Perhaps its biggest advantage is adaptability.
