Summary
This collection of papers, mainly physical and dating from 1895, documents Jagadis Chandra Bose's investigations into the optical properties of electric waves, brought down to within a few octaves of visible light. The central argument is that non-living matter, such as metals, exhibits an electric response to stimulus that mirrors the response of living matter, showing fatigue under continuous stimulation, enhancement under chemical stimulants, and permanent abolition under poisons. Bose's subsequent work aimed to establish the generalization of the essential unity of physiological mechanism in plant and animal life, suggesting that the response of living tissues is ultimately the expression of physico-chemical reactions. The volume includes papers on coherence, polarization, double refraction, and rotation of the plane of polarization, as well as the beginnings of Bose's application of physical methods to the study of living matter. A reader takes away a concrete demonstration that inorganic substances respond to mechanical and electrical stimulus in ways analogous to living organisms, challenging the boundary between the living and non-living.
Key concepts
- Electric response of non-living matter — The phenomenon where metals exhibit fatigue, enhancement, and abolition under stimulation, similar to living matter.
- Self-recovering coherer — A device for studying the cohering action of different metals in response to electric waves.
- Strain theory of photographic action — A model proposing that photographic effects arise from mechanical strains induced by radiation.
- Crescograph — A high-magnification instrument for recording growth and responses in plants, including the magnetic crescograph.
- Photosynthetic recorder — A device for measuring photosynthesis, as described in Bose's later work on plant physiology.
- Vegetable photo-electric cell — A plant-based cell that produces an electric response to light stimulation.

Popular questions readers ask
- If you were explaining Bose's method of generating shorter wavelength electric waves to a layperson, what specific advantage or breakthrough did this technique offer compared to existing methods, and what new scientific avenues did it consequently open up for study?
- Bose observed "electric response of non-living matter" exhibiting fatigue and enhancement, akin to living tissue. How does this finding challenge the fundamental scientific distinctions between animate and inanimate matter, and what implications might it have for our understanding of the origins of biological processes?
- What is the logical chain of reasoning that connects Bose's observations of "electric response" in both non-living and living matter to his generalization about the "essential unity of physiological mechanism in plant and animal life"?
- Consider Bose's transition from studying pure physical phenomena (electric waves) to applying physical methods to living matter. What unique perspectives or tools might a physicist bring to the study of biology, and how might this interdisciplinary approach have enabled discoveries that traditional biologists might have overlooked at the time?
- J. J. Thomson notes Bose's influence on the "revival in India, of interest in researches in Physical Science." How might Bose's work, beyond its specific scientific content, have served as a catalyst for broader scientific and national development in India during that era?
