From Artemis to Your Smartphone: How Physics is Reshaping Our World
The year is 2026, and humanity stands on the cusp of returning to the Moon with NASA’s Artemis II mission. But the implications of this leap for humankind extend far beyond lunar exploration. As physicist Head Jae-hyun explains in his new book, Physics That Invited the Universe, the principles governing the cosmos are inextricably linked to our everyday lives, driving technological advancements and shaping our understanding of the world.
The Expanding Reach of Physics in Modern Technology
Go Jae-hyun, a professor at Hanyang University’s Semiconductor & Display School, doesn’t simply list the achievements of modern physics. Instead, he focuses on the process of questioning and exploration that broadens our perspective. His book delves into 46 questions tackled by scientists worldwide, drawing on recent research over the last decade.
This isn’t abstract theory; it’s the foundation of technologies we rely on daily. Consider the smartphone in your pocket. The display utilizes principles of light and quantum physics. Wi-Fi and LiDAR, crucial for autonomous vehicles and advanced sensors, are rooted in electromagnetic theory. Even seemingly unrelated fields like meteorology – understanding phenomena like typhoons, hurricanes, and even the formation of dust particles – rely on a deep understanding of physics.
Beyond the Screen: Physics and the Future of Materials Science
The book explores the world of materials science, highlighting innovations like reinforced glass, quantum dots, and nanoparticles. These aren’t just incremental improvements; they represent fundamental shifts in how we design and build things. Structural color, a phenomenon where color is produced by the microscopic structure of a material rather than pigments, is another area poised for significant advancement. Imagine buildings that change color with the weather or clothing that adapts to your body temperature – all powered by physics.
Did you realize? The development of stronger, lighter materials, driven by physics research, is crucial for space travel, allowing for more efficient rockets and spacecraft.
The Interplay of Climate, Space, and Everyday Life
Go Jae-hyun’s work emphasizes the interconnectedness of seemingly disparate fields. The same physics that governs the behavior of light and matter in a laboratory also dictates the dynamics of Earth’s climate. Understanding these connections is vital for addressing global challenges like climate change and developing sustainable technologies.
The book touches upon the role of physics in understanding atmospheric phenomena, from the formation of typhoons to the behavior of microscopic dust particles. This knowledge is essential for improving weather forecasting, mitigating the effects of natural disasters, and developing cleaner energy sources.
A Scientist Bridging the Gap Between Research and the Public
Go Jae-hyun has a long history of making complex scientific concepts accessible to a wider audience, having authored previous books like A Little Knowledge of Light, A Little Knowledge of Electromagnetism, and A Little Knowledge of Quantum Mechanics. He has also contributed science columns to several Korean newspapers, including the Hankook Ilbo, JoongAng Ilbo, and Naeil Shinmun.
Pro Tip: To deepen your understanding of these concepts, explore online resources from organizations like NASA and the American Physical Society.
