                                                Sir Jagadish Chandra Bose


Welcome to my blog and thank you for this much support. So let's start. Today's blog is based on "Sir Jagadish Chandra Bose". Sir Jagadish Chandra Bose was an Indian polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction. He pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. 


A crater on the moon has been named in his honor. Born in Mymensingh, Bengal Presidency, during British governance of India, Bose graduated from St. Xavier's College, Calcutta. He went to the University of London, US to study medicine, but could not pursue studies in medicine because of health problems. Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at Cambridge and returned to India. He joined the Presidency College of the University of Calcutta as a professor of physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made remarkable progress in his research of remote wireless signaling and was the first to use semiconductor junctions to detect radio signals. However, instead of trying to gain commercial benefit from this invention, Bose made his inventions public to allow others to further develop his research.


Bose subsequently made several pioneering discoveries in plant physiology. He used his invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions because of peer pressure, his objections to any form of patenting were well known. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as quivering of injured plants, which Bose interpreted as a power of feeling in plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).


In 2004, Bose was ranked number 7 in BBC's poll of the Greatest Bengali of all time.
His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli (e.g., wounds, chemical agents) in plants, which were earlier thought to be of a chemical nature. These claims were later proven experimentally. He was also the first to study the action of microwaves in plant tissues and corresponding changes in the cell membrane potential. He researched the mechanism of the seasonal effect on plants, the effect of chemical inhibitors on plant stimuli and the effect of temperature.

                                        The curriculum of our current education system Today's blog is based on " The curriculum of our current education system ". I wholeheartedly agree that the tight curriculum of our current education system leaves no room for imagination and creativity. The academic pressure is so much on them, they have forgotten their innate creativity and imagination. They are always under the pressure of studies. This pressure is put on them from the beginning of the session. Formative assessment activities of all the subjects, studies and their assignments of all the subjects, unit tests, co-curricular activities, homework, classwork, projects, practical exams, summative examination, date sheet, result, again the new term, etc. So much of pressure on the young growing children! Are we educating them or training them in the art of being stressful throughou...
