Jagadish Chandra Bose

Jagadish Chandra Bose was a great Indian scientist. He has made an early flight in his life and invented several electrical devices. He contributed significantly to electronics, plant science, and radio physics.

Bose had an interest in science from an early age. He conducted experiments on Mimosa pudica and demonstrated that it closes its leaves when touched or shaken. His experiments were published in 1887. He also explained that this action occurs even if the leaf is not physically connected with its roots (called ‘rootless’). This proved that plants had a nervous system like animals, though rudimentary. In this article, you will learn about Sir Jagadish Chandra Bose, his journey as an early writer of science fiction, and his work in radio and microwave optics and plants.

Sir Jagadish Chandra Bose: Early Life

Sir Jagadish Chandra Bose(1858-1937) was born on November 30th, 1858, at Munshiganj (now in Bangladesh). His father, Bhagavanta Chandra Bose, was a deputy magistrate, and his mother, Prasanna Kumari Devi, came from a zamindar family. Jagadish’s father died when he was only two years old, so he stayed with his uncle, who taught him Bengali literature and law. At 9, he went to Calcutta (now Kolkata), where he studied at Hare School before joining Hindu College.

Jagadish Chandra Bose is a scientist and physician, who made valuable contributions to plant physiology, and his work on electromagnetic radiation led to the development of the Crescograph. He was also a writer and philosopher. He studied at Presidency College, Calcutta (then known as Calcutta Medical College), and graduated with honours in natural science (1879), winning the Governor General’s Medal for standing first in physics. After graduation, he was an assistant professor at Presidency College until 1887, when he left for England to complete his studies there. In 1890 he became a professor at Presidency College. 

While in England, he studied electronics under William Bragg and was awarded a scholarship that allowed him to continue his studies at Cambridge University. He worked with Sir William Crookes on various scientific experiments, including colour photography.

Jagadish Chandra Bose’s Contribution to Science

Jagadish Chandra Bose was a Bengali scientist, botanist and physicist. He is considered the father of radio science and was the first person to use semiconductor junctions to detect radio signals in 1894. Sir Jagadish Chandra Bose was a scientist, biologist and botanist who made several significant scientific contributions. He built several devices for different purposes, including the Crescograph, an instrument measuring plant response to various stimuli.

In 1895, he sent a paper on his findings to the Asiatic Society of Bengal. Jagadish Chandra Bose’s contribution as an early writer of science fiction is immense. He worked on wireless telegraphy from 1893. He believed that electromagnetic waves could travel through space at the speed of light. His paper “On the Electrical Response of Plants” was published in the Journal of Scientific Instruments in 1895, and it discussed some of his experiments on plants using electrical stimuli.

Crescograph

Jagadish Chandra Bose was one of the most famous scientists in India. He was the first Indian scientist to study plants scientifically. He also invented Crescograph, which is used to measure growth in plants. He is known for inventing the Crescograph; an instrument used to estimate plant change. He also developed a technique for staining living tissues with fluorescent dyes to make them visible under the microscope. His work on plants led him to conclude that plants were capable of responding to external stimuli. He also conducted experiments on animals like frogs and showed that they too had similar responses as plants. He was thus able to prove that all living things have some life force or nirvana that enables them to respond to external stimuli like light, heat etc. This experiment paved the way for further studies on plant senses by other researchers like Charles Darwin, Robert Hooke, etc.

Crystal Detector

Bose invented the Crystal Detector, an early version of a radio receiver that could receive signals from around 60 metres away from the transmitter without wires or antennae! It was beneficial for communication between ships during World War I because it could transmit messages through water without cables or antennas. Soldiers also used it during World War II, but it lost its popularity after the war ended due to its bulky size.

Conclusion

Jagadish Chandra Bose has expertise in several fields of science, including botany and telecommunications. He is considered one of the fathers of radio science and studied microwaves. He first used semiconductor junctions to detect radio signals, thus demonstrating wireless communication for the first time in 1895. Bose’s earliest research was on plant countenance, but this did not attract him as much as animal physiology which he studied at Calcutta Medical College under Professor John Perry. His studies there were sponsored by an Indian Civil Service Scholarship from the British Government.
