Physics inside living systems: motion, signals and measurement
A scientific lens on pressure, bioelectricity, transport and the limits of measured signals.
Physiology is physical. Pressure gradients drive circulation, diffusion supports exchange, and electrical properties enable physiological signaling. Biophysics provides the mathematical frameworks for asking how these processes operate.
A measured waveform is the output of a sensor, a sampling method and an analytical process. It may reflect underlying biology, but it also contains noise and uncertainty. Separating those influences calls for calibration, controls and a well-defined biological question.
Computational models can describe aspects of mechanical or electrical systems, yet model assumptions must be tested and interpretation must remain proportionate to evidence.
Our interest in physical measurement is educational and research-oriented, with no claim of proven new medical applications.
