Electromagnetic Waves and Anekāntavāda

 

Electromagnetic Waves and Anekāntavāda

Today we all know much about electromagnetic (EM) waves. We use them in almost every area. Examples are radio waves in communication, Microwave cooking, and X-rays in the Health Sector. However, the characteristic of EM waves was a disputed topic. Isaac Newton believed that EM waves are a collection of particles. As he was the greatest polymath of his time, almost everyone believed that. His contemporary Christian Huygens suggested that EM is a wave. But Isaac Newton was most famous then, and thus the idea of Christian Huygens remained in a drawer for 100 years.

Thomas Young challenged the idea of the particle nature of EM waves with his Double Slit Experiment. Later experiments by Augustin Jean Fresnel supported the wave nature of EM waves. Also, the electromagnetic theory of Maxwell predicted the speed of light correctly. Thus, almost everyone started to believe that EM waves have a wave nature only.

But the wave nature of light failed to explain the Photoelectric Effect, which was later explained by Albert Einstein by considering the particle nature of EM waves.

Later, scientists agreed that the EM wave has both natures – Particle and Wave. And the debate settled.

Should we stop here our search or understanding of Electromagnetic Waves?

Clearly, Big No; we should be open to new ideas and understanding. We should not be extremists and believe in only one idea or concept.

Jainism believed in the idea of Anekāntavāda – Ultimate truth and reality are complex and have multiple aspects. I think this is also true in the Scientific world. The ultimate reality of every atom is complex and has multiple aspects, be it a Photon or an electron. 

Christian Huygens proposed that electromagnetic (EM) waves were mechanical waves, propagating through a medium called the "ether." However, modern physics views EM waves as non-mechanical, propagating through a vacuum without the need for a physical medium. The absence of experimental evidence for the ether has led to its dismissal.

While it's important to maintain an open mind and consider alternative explanations, it's equally crucial to base scientific understanding on empirical evidence. 

At present, there's no compelling evidence to suggest that EM waves are mechanical or that the concept of the ether is valid.

However, as our understanding of the universe continues to evolve, it is possible that future discoveries may challenge our current paradigms. It's essential to remain open to new ideas and be willing to adapt our theories as new evidence emerges.

Temple

Temples hold a pivotal position within Indian society, exhibiting significant variations in scale and architectural design. They can range from a single stone beneath a tree, serving as a farmer's place of worship, to expansive structures like the Sri Ranganathaswamy Temple in Tiruchirappalli, Tamil Nadu .   The fundamental question arises: what constitutes a temple? Is there a universally accepted definition?   Pandit Jawaharlal Nehru famously referred to dams as "temples of modern India" during the inauguration of the Bhakra Nangal Dam on the Sutlej River .   Jhunjhunu , a district nestled in the vibrant state of Rajasthan, stands as a testament to a profound legacy, deeply rooted in the intertwined heritage of valiant warriors and diligent farmers. This unique confluence of courage and cultivation has shaped the very fabric of its communities, imbuing them with a distinct character that resonates through generations.   One of the most striking manifestations of...

Unplanned

In contemporary society, planning permeates nearly every aspect of our lives. A significant portion of the population exhibits a reliance on meticulous planning, often stemming from an apprehension of uncertainty. We meticulously plan our diets , travel itineraries , career paths, academic examinations, public addresses, lectures, weddings, and birthday celebrations, among countless other endeavours.   While planning is an undeniably valuable tool, excessive adherence to it can be detrimental. It is imperative to cultivate adaptability and preparedness for unforeseen circumstances.   Numerous literary works and online resources extol the virtues of planning. However, this discourse aims to explore the concept of the unplanned in an unstructured manner. Consequently, should this note appear disorganized or disjointed, it is a deliberate reflection of its unplanned genesis. The Unplanned Fast Trek Our trekking expedition in Pune was entirely spontaneous. We arrived at the loc...

The Dark Side of Synthetic Fibers: Beyond the Obvious

Let's get directly to the point. I'm writing this because, while the environmental and health impacts of synthetic fibers are becoming more widely known, there's a deeper, systemic issue that often goes unaddressed. If you search for synthetic fiber online, you will find extensive information detailing the well-documented negative impacts these materials have on both the environment and human health—facts that many consumers remain unaware of. This includes the massive microplastic shedding during washing, the non-biodegradable nature of the materials (like polyester , nylon , and acrylic ), and the potential for harmful chemical leaching from the dyes and finishing treatments used in their production. I strongly encourage you to read these reports and find out the full negative scope of these fibers on our planet and our bodies. I do not want to simply repeat all that information here. I want to share some other, less discussed, but equally critical facts about the curr...
