Ferenc Krausz: A Journey Guided by Questions

The Nobel Foundation has published Ferenc Krausz’s biographical summary on its official website. The Nobel Prize-winning physicist’s text is not only a chronicle of a scientific career, but also a deeply personal reflection on his family background, the fundamental role of Hungarian education, and his belief that basic research can transform the future of healthcare.

Krausz begins with a key insight: every serious endeavor must start with a good question. His question was whether the motion of electrons, as predicted by the Schrödinger equation, can be observed in real time. This question ultimately led to the emergence of attosecond physics.

He emphasizes that his interest in the natural sciences was not the result of a sudden realization but was shaped by the mindset of his teachers. His first formative experiences came from Károly Kiss in Mór, who introduced him to the universality of physical laws and the power of mathematics, setting him on his path. Later, lectures by figures such as Károly Simonyi and György Marx further shaped his thinking, instilling not only a strong theoretical foundation but also a deep enthusiasm for physics. At the Budapest University of Technology and Economics, Tibor Juhász introduced him to the world of laser technology, where encountering picosecond pulses ultimately defined the direction of his research career.

The most compelling part of the text looks toward the future. Krausz argues that attosecond technology is not merely a theoretical achievement in physics but may become a key tool in practical medicine.

He concludes his biography with a global appeal: the success of modern science lies in human cooperation. He calls on political leaders to strive for connection rather than separation, emphasizing that the greatest challenges of our civilization can only be solved through joint, cross-border efforts.
