A tuning fork, a glass bowl with rings of water, and a glass prism as symbolic objects; a portrait badge of Anna and Herbert in the lower right corner.

How do vibrations and light affect different materials? This article explains resonance, standing waves, acoustic levitation, and spectroscopy using specific mechanisms. You’ll learn what role materials and experimental setups play, and why a single frequency neither fully describes an experiment nor proves a health effect.Continue reading

A stone, a glass sphere, a tuning fork, and ripples in water in a symbolic still-life composition; Anna and Herbert’s portrait badge in the lower right corner.

Matter, waves, and perception describe different aspects of our world. This article explains in an accessible way what quantum physics tells us, how seeing, hearing, and smelling work, and why these insights do not lead to arbitrary claims of healing. Through thought experiments relevant to everyday life, you’ll learn to distinguish scientific concepts from metaphors and personal interpretations.Continue reading
