Jagdish Chandra Bose
Jagdish Chandra Bose, Indian-Bengali physicist and biophysicist (Bikrampur, Munshiganj District, Bangladesh 30 November 1858 – Giridih, Jharkhand, India 23 November 1937) ACHIEVEMENTS Measured refractive index from a number of substances Invented galen detector the first semiconductor and was the first to employ it as a detector of electric rays and radio waves (1904) Demonstrated that electromagnetic waves weren’t obstructed by solid walls and it could be transmitted wireless (1895) Demonstrated radiotransmission independently of Marconi (1895) First to use semiconductor junction for detecting radio waves Suggested the existence of Sun electromagnetical radiation (confirmed in 1944) Discovered metal fatigue and retrieval Showed that materials fatigue was due to molecular cyclic changes Since 1915 concentrated in plant physiological studies Invented crescograph in order to study plants physical motion and growth rate Invented transpirograph and photossinthetic recorder Demonstrated plants minute movements under external stimulation Demonstrated electric nature conduction occurring due many stimuli in plants Showed that plant tissues produce electrical response similar that animal under distinct kinds of stimulation Claimed have observed neural microscopic threads in vascular bundles that demonstrated activity when adjacent parts were stimulated Proposed the theory that electromechanical pulsations of living cells were responsible for sap ascension in plants (1927). These cells would be like cardiac pulsating cells lying on cortical tissue in crescent layers. This theory is alternative to Dixon-Joly hypothesis. First to study the action of microwaves in plant tissues and correspondent changes in cellular membrane potencial ENUNCIATED LAWS IN PLANT PHYSIOLOGY General Law of responsive motion “the mechanical response occurs on concavity of most excited side of plant” Laws of polar excitation in plants Growth Laws Laws about curvature of responsive growth Electric response laws Law of polar effects under high electromotive forces Torsional response laws INVENTIONS Mercury coherer with a phone (1899) Many microwaves components (1890s) Ressonance Recorder Conductivity Balance Magnetic Radiometer A new electric polariscope (1895) Bubbler A producing apparatus of very short waves electric radiations Waveguides Horn antennas Polarizers Dielectric lenses Prisms Electromagnetic radiation detectors Oscillating recorder Diametric contraction apparatus Kunchangraph, a device analogous to miograph Recording microscope for record the growth of roots Morograph Recording optical lever Electro thermal recorder Shosungraph HONORS Bosea Das et al. 1996 (Bacteria)
