The way we think and talk about science can actually hold us back from understanding the world. Our usual way of thinking - using cause-and-effect language - isn't always the best way to understand complex things.

Introduction
The pursuit of scientific knowledge is a continuous endeavor to refine our understanding of the world. As we push the boundaries of human understanding, we are confronted with the limitations of our existing frameworks and the need for new perspectives. This paper addresses a fundamental aspect of scientific inquiry: the language and categories we use to describe the world.
Our current scientific language is rooted in a causal paradigm, where events are described as cause-and-effect relationships. However, this language is often inadequate for describing complex phenomena, where relationships are multifaceted and context-dependent. Furthermore, our categories of thought are often based on historical and cultural contexts, which can limit our ability to develop new insights.
Recent advances in physics, philosophy, and cognitive science have highlighted the need for a new approach. The study of complex systems, nonlinear dynamics, and emergent phenomena has shown that traditional causal language is insufficient for describing the intricate web of relationships that govern the behavior of complex systems.
In response to these challenges, we propose a new framework for scientific inquiry, one that emphasizes descriptive language, pattern description, and conceptual shifts. By focusing on the relationships and patterns that govern the behavior of complex systems, we can develop a deeper understanding of the world and uncover new insights.
This paper explores the implications of this new framework through a case study of the solid-liquid distinction and physical laws. By examining the fundamental concepts of symmetry, restoring forces, and pattern description, we demonstrate the limitations of traditional causal language and the need for a descriptive approach.
Our work draws on insights from physics, philosophy, and cognitive science to develop a more complete understanding of the world. We argue that by recognizing the limitations of existing categories and embracing new ones, scientists can develop a deeper understanding of complex phenomena and make new discoveries.
In the following sections, we will explore the solid-liquid distinction, physical laws, and the implications of our new framework for scientific inquiry. We will demonstrate how this framework can be applied to develop new insights and understandings, and highlight the importance of interdisciplinary approaches in advancing our knowledge of the world.
The Solid-Liquid Distinction: A Case Study
The distinction between solid and liquid states is a fundamental concept in physics, characterized by the presence or absence of restoring forces. In liquids, there is no restoring force when a paddle is twisted, whereas in solids, a restoring force arises due to shear deformations (1). This difference has significant consequences, including the existence of two distinct modes of sound in solids (P and S waves) (2).
To illustrate this concept, consider a thought experiment involving a paddle submerged in a liquid. When the paddle is twisted, the liquid molecules surrounding it adjust their positions to accommodate the new orientation. There is no resistance to this motion, and the paddle can be twisted indefinitely without encountering any restoring force. In contrast, if the paddle is submerged in a solid, twisting it will cause the surrounding molecules to resist the motion, resulting in a restoring force that attempts to return the paddle to its original orientation.
This difference in behavior is a direct result of the arrangement of molecules in solids and liquids. In liquids, molecules are free to move past one another, resulting in a lack of resistance to shear deformations. In solids, molecules are arranged in a crystalline structure, which provides resistance to shear deformations and gives rise to restoring forces.
Symmetry and Restoring Forces
Symmetry plays a crucial role in understanding the solid-liquid distinction. In liquids, symmetry under rotations in space characterizes the state, whereas in solids, this symmetry is broken, leading to restoring forces (3). To understand this concept, consider a sphere submerged in a liquid. The sphere's symmetry under rotations in space is preserved, as it can be rotated without encountering any resistance.
In contrast, a sphere submerged in a solid will experience resistance to rotation, resulting in a breaking of symmetry. This breaking of symmetry is a direct result of the crystalline structure of the solid, which provides resistance to shear deformations.
The breaking of symmetry in solids has significant consequences, including the existence of restoring forces and the emergence of new physical properties. For example, the breaking of symmetry in solids gives rise to piezoelectricity, the ability of certain materials to generate an electric charge in response to mechanical stress (4).
In conclusion, the solid-liquid distinction is a fundamental concept in physics, characterized by the presence or absence of restoring forces. Symmetry plays a crucial role in understanding this distinction, with liquids exhibiting symmetry under rotations in space and solids exhibiting broken symmetry. This broken symmetry gives rise to restoring forces and new physical properties, making it a critical concept in understanding the behavior of solids.
Physical Laws: An Alternative Language
Physical laws are often described as statements of the form "If A then B," where A and B are limited characterizations of the universe (4). However, this language can be misleading, as it implies a directionality and intentionality that is not present in the underlying physical processes. We propose an alternative language that avoids these pitfalls and emphasizes the importance of precise language in scientific inquiry.
In our alternative language, physical laws are described as patterns of relationships between different aspects of the universe. These patterns are not causal in nature but rather descriptive, highlighting the intricate web of relationships that govern the behavior of physical systems.
For example, consider the law of universal gravitation. In traditional language, this law is stated as "Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them." Our alternative language would describe this law as a pattern of relationships between masses and distances, highlighting the intricate web of gravitational interactions that govern the behavior of celestial bodies.
Pattern Description and Causation
Physical laws can be categorized into two types: those that describe patterns across different times and those that articulate the nature of a pattern itself. The former type of law is often associated with causation, where a cause leads to a specific effect. However, the latter type of law does not necessarily imply causation, as it describes the inherent properties of a system (5).
To illustrate this concept, consider the laws of thermodynamics. The second law of thermodynamics describes the pattern of increasing entropy over time, which is often interpreted as a causal relationship between the past and the future. However, this law does not imply causation but rather describes the inherent properties of thermodynamic systems.
In contrast, the laws of motion describe the pattern of relationships between positions, velocities, and accelerations, without implying causation. These laws articulate the nature of the pattern itself, highlighting the intricate web of relationships that govern the behavior of physical systems.
Our alternative language emphasizes the importance of distinguishing between these two types of laws, avoiding the pitfalls of implied causation and directionality. By recognizing the descriptive nature of physical laws, we can develop a deeper understanding of the intricate web of relationships that govern the behavior of the universe.
Agentive Terms and Their Limitations
Agentive terms, such as "cause" and "effect," can be useful in describing certain patterns, but they can also be misleading. In some cases, these terms may imply a directionality or intentionality that is not present in the underlying physical processes (6). This can lead to a misunderstanding of the nature of physical laws and the relationships they describe.
For example, consider the concept of causality. In everyday language, causality implies a directionality, where a cause leads to a specific effect. However, in physical laws, causality is often not present. Instead, physical laws describe patterns of relationships between different aspects of the universe.
To illustrate this concept, consider the law of conservation of momentum. In traditional language, this law is stated as "The total momentum of a closed system remains constant over time." However, this language implies a directionality, where the momentum at one time causes the momentum at a later time. Our alternative language would describe this law as a pattern of relationships between momenta at different times, avoiding the implication of causality.
Conceptual Shifts and Category Formation
Scientific progress often involves conceptual shifts, where new categories of thought are formed. This process requires recognizing the limitations of existing categories and embracing new ones. The distinction between solid and liquid states is a prime example of such a conceptual shift, as it involves recognizing the importance of symmetry and restoring forces (7). Conceptual shifts can be challenging, as they require a re-evaluation of existing knowledge and a willingness to embrace new ideas. However, they are essential for scientific progress, as they allow us to develop new insights and understandings of the world around us.
Category formation is a critical aspect of conceptual shifts. New categories of thought are formed by recognizing patterns and relationships that were previously unknown or misunderstood. For example, the category of "phase transitions" was formed by recognizing the patterns of behavior that occur when a system changes from one state to another.
Our alternative language emphasizes the importance of category formation in scientific inquiry. By recognizing the limitations of existing categories and embracing new ones, we can develop a deeper understanding of the world around us and make new discoveries that were previously unknown.
Implications for Scientific Inquiry
Our framework has significant implications for scientific inquiry, emphasizing the importance of precise language, category formation, and conceptual shifts. By recognizing the limitations of existing categories and embracing new ones, scientists can develop a deeper understanding of complex phenomena and make new discoveries.
One major implication is the need for scientists to be aware of the language they use and the categories they employ. By using precise language and avoiding agentive terms, scientists can avoid implying causality or directionality where none exists. This can lead to a more accurate understanding of physical laws and the relationships they describe.
Category formation is important in scientific inquiry. By recognizing patterns and relationships that were previously unknown or misunderstood, scientists can form new categories of thought and develop new insights. This can lead to new discoveries and a deeper understanding of the world around us.
Furthermore, our framework emphasizes the importance of interdisciplinary approaches to scientific inquiry. By combining insights from physics, philosophy, and cognitive science, scientists can develop a more complete understanding of complex phenomena. This can lead to new discoveries and a deeper understanding of the world around us.
Conclusion
In this paper, we've explored how the way we think and talk about science can actually hold us back from understanding the world. We looked at how we describe the difference between solids and liquids, and how we think about physical laws. What we found is that our usual way of thinking - using cause-and-effect language - isn't always the best way to understand complex things.
Instead, we suggest using a more descriptive approach, focusing on patterns and relationships. This can help us discover new things and understand the world in a deeper way. It's like looking at a puzzle and seeing how all the pieces fit together, rather than just focusing on one piece at a time.
This new way of thinking can have big implications for science and technology. By understanding how complex systems work, we can develop new solutions to real-world problems. And by working together across different fields - like physics, philosophy, and cognitive science - we can gain a more complete understanding of the world.
Ultimately, our goal is to encourage scientists and scholars to think differently about their work. By questioning our assumptions and exploring new ideas, we can gain a deeper understanding of the world and make new discoveries. We hope this paper will inspire others to join us on this journey of exploration and discovery.
