[AK View] "Easier, Even Easier"... The Golden Age of 'Quantum'

Even Amazon's Founder Was Humbled by "Quantum Mechanics"
Introductory Books Explaining Complex Theories Become Bestsellers
Worth Reading for Investment Insights and Intellectual Curiosity

Quantum mechanics is often regarded as the "final boss" of physics. This is a story I heard from someone who majored in physics. According to him, during his undergraduate years, it was common for students to fail to graduate because of this required course alone. Retaking the class was the norm, and some students barely managed to graduate by pleading for just a passing grade of 'D.' Even students known for their academic prowess repeatedly found themselves defeated in the face of quantum mechanics.

An anecdote from Amazon founder Jeff Bezos's college days perfectly illustrates the difficulty of this field. Having entered the physics department at Princeton University, Bezos was an elite student who received top marks in nearly every course during his undergraduate studies. However, his dream of becoming a physicist was shattered when he encountered quantum mechanics. After struggling for 12 hours to solve a partial differential equation in quantum mechanics, Bezos watched as a friend-considered the smartest at Princeton-solved the same problem in an instant, leading to a moment of harsh self-realization. Ultimately, Bezos gave up on physics, switched to computer science, and embarked on the path of entrepreneurship. In a past interview, Bezos said, "One of the biggest lessons I learned at Princeton was realizing that I wasn't smart enough to be a physicist."

Despite its notorious difficulty, quantum mechanics has recently become a "hot" keyword in Korean bookstores. "The First Encounter with the Quantum World," a book by Korea University professor Chae Eunmi, has become a bestseller in the science section of major bookstores. Introductory books that explain quantum mechanics in accessible terms, such as "The Minimum Quantum Mechanics Everyone Needs to Know but No One Does" and "The Age of Quantum," are being published in succession.

Quantum mechanics is a field that delves into the invisible microscopic world, exploring unfamiliar entities like electrons, photons, spins, and wave functions-concepts that are impossible to grasp with ordinary senses. Successful physicists go out of their way to explain their research to the public, likely because they genuinely want to share their world with more people. However, the general public is more interested in the "money" that can be made from quantum technology.

Technologies such as quantum computers, quantum communication, and quantum sensors are hailed as key principles that will change the future. Investment, policy, and industrial strategies are all converging on this keyword. The stock prices of quantum computing companies have fluctuated by tens of percent within a year, even though their revenues are still negligible. Investment communities are abuzz with the expectation that "the world will change when quantum arrives." This year, the government increased its quantum-related budget by more than 50% compared to the previous year, and there are forecasts that the global quantum technology market will reach tens of trillions of won by 2030. Meanwhile, there are also concerns that quantum computers could undermine existing encryption systems, threatening the security of virtual assets like Bitcoin.

As both expectations and anxieties grow, so do sales of introductory books on quantum mechanics. For investors, understanding exactly what technology their money is going into brings peace of mind. Policymakers and business leaders also find it difficult to devise strategies without at least a basic understanding of the concept. As a result, physicists who can explain complex theories in simple terms now appear in the media far more frequently than before.

Nobel laureate Richard Feynman once said, "If you think you understand quantum mechanics, you don't understand quantum mechanics." But there's no need to be bound by this. Quantum mechanics is no longer just an esoteric formula in a textbook; it is quietly transforming into another mechanism that shapes markets, power, and everyday choices. You don't have to be an investor. Sometimes, satisfying your intellectual curiosity with a single introductory book and getting a sense of how technology and the times are changing is more than enough.
