Explore the electrical language of life and what makes living matter different from the inert.
This concise volume surveys how plants and animals reveal their vitality through electrical signs, and how scientists test those signals with simple, careful experiments.
This edition presents the core ideas behind physiology’s focus on life, from the signs that indicate living processes to practical demonstrations of skin and tissue responses. You’ll see how researchers compare living surfaces to inert ones, and how experiments with fruit peels, frog skin, and other tissues illuminate the active flow of energy in living systems.
- Clear explanations of life’s four universal signs, with a focus on electrical indicators.
- Step-by-step descriptions of simple, repeatable experiments that illustrate how living tissue responds to stimulation.
- Discussion of how scientists interpret results using accessible notation to compare outcomes across different specimens.
- Historical context showing how early electro-physiologists observed and interpreted currents and polarisation.
Ideal for curious readers of scientific history and physiology, this book suits students and general readers who want a grounded, non-technical introduction to the study of life’s signs.
