This article compares the macro and micro worlds and explores the possibility that microscopic theories, such as quantum mechanics, can be applied to the macro world, allowing for future predictability and revolutionary change.
The world we live in is a visually distinguishable macroscopic world. In other words, we live in a world where we can distinguish objects by receiving photons from them and perceiving them with our eyes. However, we know nothing about very small microscopic systems, such as atoms, either because of the limitations of our eyes or because the microscopic world is as small as a photon. The rapid development of physics in the 20th century has led to the exploration of the microscopic world and the creation of many microscopic theories that cannot be applied to the macroscopic world. However, these microscopic theories were created by humans in the macroscopic world, so perhaps they can be applied to the macroscopic world from a different perspective.
Scientific inquiry is driven by human curiosity and imagination. Ancient philosophers explored the fundamental principles of the universe and nature by imagining the unseen world. Modern physics continues this tradition, using scientific methodology and advanced technology to explore the microscopic world. Disciplines like quantum mechanics play an essential role in understanding the fundamental nature of matter, which has had a profound impact on the development of modern technology.
Humans have developed universal theories about the microscopic world, which is invisible to our eyes, by simply reasoning about it and testing it with experiments. To date, numerous theories have been developed to explain the microscopic world through such reasoning and experimentation, and they have formed a scientific system called quantum mechanics. In quantum mechanics, all particles are not fixed in one location like in the macroscopic world, but exist probabilistically. This is because if we experimentally measure a particle α at one moment, it will be at a different location at another moment, and the measurement will change from moment to moment. As a result, all calculations in quantum mechanics are calculated as probability wave functions (the probability of a quark being in one state or another), and the results are also probabilities.
Since we can’t see or touch the microscopic world, we assume a system like the macroscopic world and measure energy or momentum by reading the values that occur when we change the system with operators like energy and momentum. For example, the basic principle of Schrödinger’s equation, which describes the entirety of quantum mechanics, is that when we apply an energy operator to a system in the microscopic world, we can measure the energy value that comes out of the system. Similarly, to measure the momentum of a particle in the microscopic world, we measure the momentum by assuming the system of the particle and changing the momentum operator. In the same way, humans in the macroscopic world theorize and explore the microscopic world by assuming a stochastic system to measure the very small microscopic world and measuring the values that result from changing the system with operators.
But this scientific approach is not limited to physical phenomena. Theories of the microscopic world have influenced other fields of study, including philosophy, biology, and chemistry. Quantum biology, for example, is an attempt to explain the phenomena of life by applying the principles of quantum mechanics to biological systems. This interdisciplinary approach is opening up new fields of study and expanding existing bodies of knowledge.
But do these microcosmic theories necessarily apply only to the microcosm? In fact, the macro world we live in is just as unpredictable as the micro world. We can’t predict the future exactly and we don’t know what will happen where. We can only know probabilistically, and humans in the macro world think in terms of possibilities. This is similar to how quantum mechanics assumes that the state of a particle is a probability wave function. So can’t the macro world, like the micro world, assume some stochastic system and measure something by changing that system? For example, if the probability of a crime occurring in a city can be solved by assuming a stochastic wave function and applying a crime-causing operator, similar to the theory of the microcosm, we can predict in advance which locations and times are most likely to have crimes.
The key question is how to determine the “crime-causing operators” used in this approach. This is very difficult and would require years of statistics and city characteristics to be taken into account. If we can develop an operator that can change these macroscopic worlds, we will be able to predict the future probabilistically. It would be very beneficial to humans if the theories of the micro world could be applied to the macro world, but the biggest challenge is to create an operator that can change the system like the micro world.
In modern times, humans in the macro world have explored and explored the micro world, and have come up with many theories to explain phenomena that are difficult to explain in the macro world. However, do these theories necessarily apply only to the microcosm? Maybe the theories that we have spent decades exploring the microcosm will change the macrocosm, not the microcosm. In fact, macro and micro are also relative concepts, meaning that if there are other aliens who don’t see a meter as a unit like we do, but instead see thousands or hundreds of kilometers as a human meter, then what we think of as the macro world may be the micro world to them. If we were to explore the microcosm from an alien perspective, we might end up exploring the planet we live on.
Furthermore, the macroscopic application of microscopic theories to the macroscopic world is not just theoretical speculation, but has the potential to lead to real-world applications. For example, quantum computers are a new way of processing information using the principles of quantum mechanics. If this technology becomes a reality, we will be able to experience the amazing possibilities of quantum mechanics in the macro world.
What do you think? After all, even though we say we are exploring the microcosm, isn’t it really an exploration of the macrocosm we live in? If we apply the microcosmic theories that have been developed for more than 100 years to the macrocosm we live in, could we come up with even more surprising results than we have ever thought possible? By pushing the boundaries of scientific inquiry, we can achieve deeper understanding and innovation.
