Why is the fine-structure constant approximately one over one hundred and thirty-seven? Why is the proton exactly 1836 times heavier than the electron? Why is gravity so absurdly weak compared to the other forces? For more than a century, physicists have measured the fundamental constants of nature with exquisite precision—yet no one can explain why they have the values they do. Three answers have been proposed. The constants are brute accidents with no deeper explanation. They will one day be derived from a final theory.

In an era dominated by digital technology, we have long assumed that our devices—smartphones, computers, and networks—operate on the solid ground of classical physics. Yet the truth is far more profound: modern microelectronics has always rested on quantum foundations. Boris Kriger reveals how quantum mechanics quietly shaped the transistor from its inception, how effects like tunneling, interference, and decoherence were not later intrusions but essential enablers of function.
