Part 7/9:
Grunier introduced insights from historical references in experimental physics, suggesting that the careful design of electrodes in such experiments, reminiscent of Hutchison's and Tesla's work, indicates a need for minimal surface curvature to optimize electric processes. They discussed the paradox of electrode degradation in typical experimentation, underscoring the necessity for materials that could heal or regenerate in response to conditions similar to self-healing properties observed in mercury or novel alloys.
