The Crescograph is a highly sensitive scientific instrument invented in the early 20th century to measure the growth of plants.
Instrument: Crescograph.
Inventor: Sir Jagadish Chandra Bose (Indian scientist).
Purpose: To measure and magnify the growth of plants (up to 10,000x).
Discovery: Proved that plants respond to external stimuli (heat, cold, poison).
It was invented by the brilliant Indian physicist and botanist, Sir Jagadish Chandra Bose (J.C. Bose), in the early 1900s.
Plant growth is incredibly slow — invisible to the naked eye. The crescograph used a series of clockwork gears and a smoked glass plate to magnify the microscopic movements of plant growth by up to 10,000 times.
With this magnification, Bose could literally watch a plant grow in real-time.
Using the crescograph, J.C. Bose proved to the world that plants have life, feelings, and react to stimuli. He showed that plants grow faster in warm, pleasant conditions and their growth slows down or stops when exposed to toxins, cold, or physical shock. This was a revolutionary breakthrough in plant biology.
A crescograph is a scientific instrument used to measure and highly magnify the minute growth of plants.
The crescograph was invented by the pioneering Indian scientist Sir Jagadish Chandra Bose.
