Jagadis Chunder Bose (1858-1937)

Jagdish Chandra Bose (November 30, 1858 – November 23, 1937) was a Bengali physicist, biologist, biophysicist, botanist, archaeologist and science fiction writer.
He was one of the founders of radio and microwave optics research, made significant contributions to plant science, and established experimental science foundations in the Indian subcontinent.

Many of his instruments are still on display and remain largely serviceable, more than 100 years after their creation. They include various antennas, polarizers, waveguides that are used in modern designs today.

After working in the field of radio signal transmission and researching the properties of the microwave range, Bos became interested in plant physiology. In 1927, he created the theory of sap rising in plants, known today as the life theory of sap rising. According to this theory, the rise of sap in plants is initiated by electromechanical pulsations occurring in living cells.

He doubted the correctness of the most popular at that time and now generally accepted tension-cohesion theory of Dixon and Joly, proposed by them in 1894. Despite the fact that the existence of the phenomenon of back pressure in plant tissues has been experimentally proven
