Graduate Student Proves a Quantum Uncertainty Principle for Fractals The math, which combines chaos, quantum theory, and infinitely complex fractal structures, has been called a “foundational result.” Ada Zejun Shen/Quanta Magazine Introduction At the quantum scale, tiny particles behave in bizarre ways. One reason for this is the uncertainty principle, which says that the more you know about where a quantum particle is, the less you can know about how fast it’s moving, and vice versa. Recently,...
