A long time later, quantum mechanics and semiconductor band concept would supply the framework for explaining why supplies reminiscent of galena behave in another way from metals and insulators.
“What makes Bose’s work notably putting is that he was working with these phenomena earlier than the event of quantum mechanics and fashionable semiconductor band concept,” Dr Ramkarthik mentioned.
Bose’s work additionally prolonged into high-frequency electromagnetic waves. His investigations into millimetre waves reached tens of gigahertz, with historic information documenting waveguides, horn antennas and semiconductor detectors working at frequencies as excessive as 60 GHz. His 1895 demonstration of wi-fi transmission utilizing millimetre waves got here when wi-fi communication was nonetheless in its infancy. The rules he explored now underpin radar, satellite tv for pc communication and high-speed wi-fi methods.
Bose’s legacy additionally crossed disciplines, spanning electromagnetism, supplies science and plant physiology. His later experiments on vegetation could also be higher identified to the general public, however his work on electromagnetic waves and semiconductor detectors represents one other chapter in his scientific profession.
“If Bose have been alive right this moment, I don’t suppose he would limit himself to 1 discipline,” Dr Ramkarthik mentioned, stating that Bose’s pure method was to attach completely different areas and use experiments to uncover new phenomena.
Maybe the most important lesson is that discovery can precede rationalization. Bose noticed uncommon electrical behaviour with out the quantum concept wanted to clarify it. For right this moment’s researchers in superior supplies and quantum applied sciences, his work is a reminder that seemingly small observations can turn out to be the seeds of latest applied sciences, consultants mentioned.
In addition they level out that recognising such contributions issues past the analysis neighborhood, and that the lesser-known achievements of Indian scientists might be included in school-level science training to assist college students respect the nation’s scientific legacy.
