From Particles to Perceptions: Theoretical Physics, Consciousness, and the Quest for Unity

By: Aidan McCartin       

                                                    

    Sabine Hossenfelder's blog post titled "Do We Need a Theory of Everything?" delves into the intriguing and longstanding question at the heart of theoretical physics: Is a Theory of Everything necessary, and if so, what form should it take? Hossenfelder, a theoretical physicist recognized for her critical viewpoint, criticizes the widely held belief that the ultimate goal of physics is to discover a single, elegant, and all-encompassing theory that unifies all of the universe's fundamental forces and particles. She claims that the search for a Theory of Everything, which has captured physicists' imaginations for decades, has reached a threshold of diminishing returns. Instead, she proposes focusing on more practical and scientific routes, solving current outstanding topics in physics, and developing theories that may be less aesthetically beautiful but better reflect the complicated facts of the universe.

    The tension between the desire for theoretical beauty and the need to address the messiness and complexities of real-world physics is highlighted in Hossenfelder's thought-provoking blog post. She questions if simpler and more elegant theories are inevitably more correct or meaningful. Instead, she advocates for a more nuanced approach that acknowledges the importance of experimental evidence and empirical observations in directing scientific investigation. Hossenfelder's article challenges readers to reconsider the nature and purpose of scientific theorizing and provides a fresh perspective on the future of theoretical physics in an era when the pursuit of a Theory of Everything has become practically mythical.

    Similarly, this next article, "A New Theory in Physics Claims to Solve the Mystery of Consciousness" also delves into the realm of theoretical physics and its profound implications. The connection between these two pieces lies in their exploration of the fundamental nature of reality and the pursuit of answers to complex questions. This article examines the long-standing riddle of consciousness and proposes a unique idea offered by Dr. Nir Lahav and Dr. Zakaria Neemeh of Israel's Bar-Ilan University. The major question addressed is how the brain creates the rich tapestry of human subjective experience, including thoughts, feelings, and mental imagery. This continuing mystery is known as the "hard problem of consciousness." According to Dr. Lahav, ''consciousness should be investigated with the same mathematical tools that physicists use for other known relativistic phenomena." Both authors also argue that traditional approaches to tackling this specific challenge, which either assume consciousness as a non-physical phenomenon or dismiss it as an illusion, are problematic because they fail to account for the observer's point of view.

    Dr. Lahav and Dr. Neemeh offer an innovative theory of consciousness based on physics' relativity principles. They argue that consciousness is a relativistic feature that depends on the observer's point of view. According to this theory, different perspectives might result in the observation of awareness or its absence. This means that consciousness is something that happens depending on how someone looks at it, rather than being a set, unchanging thing. The authors employ the idea that looking at something from multiple angles can cause it to appear different. Their new theory improves our understanding of consciousness by integrating how it works practically with how it feels, providing us with an innovative way to think about it from both our personal experience and from an outside perspective.

    This groundbreaking theory about consciousness has significant implications for various fields like neuroscience, philosophy, and artificial intelligence. It questions traditional beliefs that divide the mind and body or that awareness is merely an illusion. Instead, it suggests that we can only completely comprehend consciousness if we study it from the perspective of the individual experiencing it. The authors advocate for philosophers and neuroscientists to collaborate in order to better understand how the brain generates conscious experiences and how the physical and mental parts of consciousness interact. This theory also opens up new avenues for research into issues such as how consciousness develops, when babies become conscious, and if artificial systems can have consciousness.

Molecules, Models, and Magic: The Exciting World of Computational Chemistry

Vrinda Modi I often spend time in a little cubicle in McLean in the freezing corporate cold wrapped in a blanket in the Hoboken summers sipping on free coffee from the office above. It almost always tastes like chalk, but the routine is so embedded in me. Hence, this is the perfect opportunity to talk a little more about my research in computational chemistry here at Stevens and the advances I expect in the next few years. This field excites me because it bridges my interest in chemistry with modern computing techniques, a powerful tool for advancing our understanding of chemical reactions and molecular interactions. This means we are a dry lab – running simulations on computers. No chemicals, no PPE, just models and algorithms. But why does computational chemistry exist in the first place, especially when chemistry is so rooted in physical matter? The answer is efficiency. Modeling molecules on a computer saves us from ordering chemicals, waiting for deliveries (a delay in chemistry t...

  Matthew P Kearney Scaling the Potential of Vertical Farming Going into 2025 and Beyond      Vertical farming may seem like something out of a futuristic movie, but they are very real in today’s agricultural industry. Vertical farming may promote a stronger relationship between urbanization and sustainable crop production. Based on recent innovations across agriculture and technology, vertical farming has the potential to revolutionize our current farming system. Through the development of vertical farming-based production lines, cities and otherwise unfarmable areas can be provided with fresh, local, and pesticide-free produce. Vertical farming and other adaptations of agriculture are not new ideas, but instead a historic and human process.      These technologies are ready to meaningfully address global food security through the technological and computational advancements in agriculture. Vertical farming has a promising future, which becomes a case...

Knot Your Average Problem: How do Tongue Ties Impact Oral Myofunctional Health?

  Hadia Hussain      Knot Your Average Problem: How do Tongue Ties Impact Oral Myofunctional Health? Sitting in the nursery of the dental office where I worked, I reviewed Baby V’s medical history and reports from the Emergency Department at Jersey City Medical Center. I found it odd that, despite multiple visits and clear signs of malnutrition, no physician had been able to diagnose the cause. Baby V, at a low weight of 12 pounds was struggling with difficulty nursing and bottle feeding, excessive gassiness, colic, clicking sounds when feeding, milk dribbling out of the mouth, and mouth breathing—but doctors had dismissed these signs, labeling him as "healthy."  It didn’t make sense as his low weight raised serious concerns.  According to Pediatric specialists Jenny Olson, DNP, and Sarha DeVrieze, ARNP, at the UnityPoint Clinic, a 9-month-old baby boy should weigh anywhere in between the range of 17 to 25 pounds. Baby V's situation was clearly a ...
