Jagadish Chandra Bose (1858–1937): The Father of Radio Science & Biophysics
Jagadish Chandra Bose was a pioneering Indian scientist who made groundbreaking contributions in wireless communication, radio waves, and plant physiology. His research was far ahead of its time, laying the foundation for multiple scientific fields, including biophysics, radio science, and microwave technology.
Jagadish Chandra Bose was born on November 30, 1858, in Mymensingh, Bengal Presidency (now in Bangladesh). His father, Bhagawan Chandra Bose, was a government official who believed in modern education but also emphasized learning from one’s own culture.
Bose initially attended Hare School in Kolkata and later joined St. Xavier’s College, where he was influenced by Father Eugene Lafont, a Belgian Jesuit known for his contributions to science education in India. He pursued higher studies in London, where he attended University of London and Christ’s College, Cambridge, specializing in physics and natural sciences.
Contributions to Science
Wireless Communication & Radio Waves 📡
Bose was one of the first scientists to experiment with radio waves, even before Guglielmo Marconi.
- In 1895, he demonstrated wireless transmission of electromagnetic waves over a distance of 75 feet in front of the British Governor in Kolkata.
- His invention, a mercury-coherer-based radio receiver, was an early predecessor of modern radio communication technology.
- Unlike Marconi, who later patented his radio inventions, Bose chose not to patent his work, believing that science should be shared for the greater good.
- His research was later acknowledged as one of the pioneering efforts in wireless telegraphy.
The Bose Crescograph: Plants Have Life 🌿
Jagadish Chandra Bose’s second major field of research was plant physiology, where he made one of the first scientific demonstrations that plants respond to stimuli like animals do.
- He invented the crescograph, a highly sensitive device that could measure plant growth and their responses to external stimuli, such as touch, temperature, and light.
- His experiments proved that plants could feel pain, get stressed, and even exhibit fatigue, much like human and animal nervous systems.
- His findings played a crucial role in the development of biophysics.
Microwave & Millimeter Waves Research 🔬
Bose was one of the first scientists in the world to work on millimeter waves (wavelengths shorter than radio waves).
- He conducted microwave experiments at 60 GHz, proving that these waves could be transmitted, reflected, and refracted just like light.
- His work laid the foundation for modern radar technology, satellite communication, and Wi-Fi.
- First Indian scientist to be recognized by the Royal Institution of London.
- Knighted in 1917 for his contributions to science.
- Established the Bose Institute in Kolkata in 1917, one of India's first research institutes dedicated to scientific advancements.
- The IEEE (Institute of Electrical and Electronics Engineers) recognized him as one of the fathers of radio science.
- He was posthumously acknowledged for his pioneering work in wireless communication and plant physiology.
Interesting Facts About J.C. Bose
✅ He never believed in patenting his discoveries, stating that "science is for humanity, not for personal profit."
✅ Albert Einstein and Nikola Tesla appreciated his work in electromagnetism.
✅ He was also a writer and published science-fiction stories in Bengali, making him one of the first science-fiction writers in India.
Jagadish Chandra Bose was a true scientific visionary whose work in radio waves, plant physiology, and microwaves laid the foundation for many modern technologies. His selfless approach to science, combined with his groundbreaking experiments, makes him one of India’s greatest scientists.
His legacy continues to inspire generations of researchers, and his contributions remain crucial in wireless communication, biophysics, and beyond.
