Atiśa Dipankara Shrijnana


Atiśa Dipankara Shrijnana (Bengali: অতীশ দীপঙ্কর শ্রীজ্ঞান Ôtish Dipôngkor Srigên) (980-1054 CE) was a Buddhist teacher from the Pala Empire who, along with Konchog Gyalpo and Marpa, was one of the major figures in the establishment of the Sarma lineages in Tibet after the repression of Buddhism by King Langdarma (Glang Darma).

[edit] Early life

Atisha is most commonly said to have been born in the year 980 in Vajrayogini village[2] in Bikrampur, the northeastern region of Bengal (located in modern day Bangladesh). His homestead in the village is still known to the local people as the "Ponditer bhita" (the homestead of the Pundit - a learned man). The exact year of his birth and death is widely disputed. Some sources indicate that Atisha was born in 982 and died in 1054, while more recent studies contend that his life began in 980 and ended in 1052.[citation needed] In any case, it is unanimously recognized that Atisha lived to the age of seventy-two. It is noteworthy that, while no direct connections can be made to the birth of Atisha, the year 980 also saw a major power shift in Bengali politics as the resurgent Pala dynasty seized control of the region, disposing of the incumbent Kamboja rulers. Atisha was allegedly born into royalty, and it would be intriguing to know if his royal status stemmed from one of these two contemporaneous contending powers.
The city of Vikramapura, the most probable candidate for Atisha's birthplace, was the capital of the ancient kingdoms of Southeast Bengal. Though the city's exact location is not certain, it presently lies in the Munshiganj District of Bangladesh, and continues to be celebrated as an early center of Buddhist cultural, academic, and political life. Similar to Shakyamuni Buddha, Atisha was born into royalty; the palace in which he was raised, aptly named the Golden Banner Palace, "had a golden victory banner encircled by countless houses and there were great numbers of bathing-pools encircled by 720 magnificent gardens, forests of Tala trees, seven concentric walls, 363 connecting bridges, innumerable golden victory banners, thirteen roofs to the central palace and thousands of noblemen". His father was the king of Bengal known as Kalyana Shri, and his mother was Shri Prabhavati. One of three royal brothers, Atisha went by the name of Chandragarbha during the first part of his life. In fact, it was not until he traveled to Tibet and encountered the king Jangchub Ö (Byang Chub Od) that he was given the name of Atisha, a Tibetan reference to peace.
The prince's birth is often described in traditional accounts as an auspicious or promising episode. For example, it is said that as Atisha was born "flowers rained down upon the city [of Vikramapura], a rainbow canopy appeared, and the gods sang hymns which brought gladness and joy to all the people". This particular description is loaded with several themes distinctly typical of Buddhist literature. The image of flowers falling from the sky appears in the episode of Shakyamuni Buddha's attainment of perfect enlightenment, and the emergence of a rainbow canopy symbolizes the reincarnation of a Bodhisattva. Most importantly, however, is that the arrival of Atisha brought certain happiness to sentient beings. This effect of Atisha's birth corresponds directly with the Buddhist concept of dedicating one's life to the uplifting and enlightenment of all conscious beings.
For the first eighteen months of his life, Atisha was sheltered and attended to by eight nurses in the royal palace of the capital city, Vikramapura. At eighteen months old, it is said that his parents then brought him into public for the first time, on a visit to a local temple in Kamalapuri. It was here that Atisha's potential as an extraordinary religious and spiritual leader initially emerged. People from all over the region gathered to witness his appearance. When Atisha learned from his parents of the crowd's status as his own subjects, he prayed that they may "be possessed of merit like that of [his] parents, rule kingdoms that reach the summit of prosperity, be reborn as sons of kings [and] be sustained by holy and virtuous deeds." Atisha then proceeded independently to worship the holy objects both inside and surrounding the temple, renouncing his ties to the world and his family and committing himself to religious pursuit.
Such an interpretation of Atisha's first public appearance, found in Buddhist texts and historical accounts, strongly reinforces a couple of critical components of Buddhist philosophy. The story clearly gives an impression of Atisha as a spiritually advanced and relatively enlightened individual at only eighteen months old. As such, the prince is seen to have acquired enough merit through virtuous actions in previous lives such that it carried over to dictate both his favorable experience as a venerated prince and enlightened personality as a compassionate individual. Moreover, Atisha's spiritual proficiency at this point is demonstrated through both kindness towards his subjects and non-attachment towards his familial, social, and overall life situation.
Mirroring the life of Shakyamuni Buddha, the young prince is depicted as having a natural capacity for swift learning in multiple fields and the practice of Dharma at a young age. He had become "well-versed in astrology, writing and Sanskrit" by the age of three, "able to distinguish between the Buddhist and non-Buddhist doctrines" by the age of ten, and would eventually become a master of the teachings of Mahayana, Hinayana, and Vajrayana Buddhism under the guidance of over 100 different instructors. As time elapsed Atisha's wish to enter the religious life strengthened, but his parents identified him as the brightest of their sons and natural successor to power. Therefore, as he turned the customary age of eleven years old, surrounding him with the luxuries and extravagance of royalty, Atisha's parents commenced the decorative courtship and matrimonial preparations so that the prince might find a bride among the kingdom's beautiful young women of nobility.
Atisha's response to his parents’ proposal as documented in Buddhist biographical texts evidences the level of commitment the young prince had for religious pursuit and enlightenment. On the eve of his wedding, Atisha experienced a momentous encounter with the Vajrayana goddess Tara, who would continue with him as a guiding spirit until the end of his life. Tara explained to the prince that in his past lives he had been a devout monk. Accordingly, he should not be overwhelmed by the lure of ephemeral pleasures in the world. If he should acquiesce, Tara continued, then "as an elephant sinks deeply into the swamp, [he], a hero, [would] sink in the mire of lust." Essentially, Tara's manifestation is symbolic for the prince's meaningful realization of his own karmic potential. The deity's metaphor is illuminating: as an elephant's enormous weight prevents it from escaping the mud, so the prince's wealth and extravagance would prevent him from spiritual awakening. With this revelation at the forefront of his consciousness, Atisha renounced his kingdom, family, and social status in order to find a spiritual teacher—or as he told his parents—to go on a hunting trip.
Buddhist sources assert that, while feigning a hunting trip, an adolescent Atisha made the acquaintance of the brahmin Jetari, a Buddhist recluse and renowned teacher. Jetari taught the young man three things: 1) taking refuge in the Three Jewels of Buddha, 2) Dharma and Sangha and 3) bodhichitta, described as the mind-oriented aspiration towards enlightenment with the intent of benefiting all sentient beings. Upon educating the young Atisha in the basic principles of Mahayana Buddhism, Jetari advised that he go to Nalanda, a Buddhist center for learning in northeastern India. In Nalanda, Atashi received once again brief instruction regarding the Bodhisattva vows under the spiritual guide Bodhibhadra, who in turn advised him to seek out a teacher renowned for his perfect meditation of perceiving emptiness, Vidyakokila.
Atisha's acquisition of the wisdom to perceive emptiness is particularly significant. It is during this stage of study that Atisha became aware of pure human nature and the fundamental freedom inherent to every sentient being's existence; a freedom exclusive of physical attachments and mental bondage. Buddhist narratives recount one story in which Atisha comes across a women alternately crying and laughing. Confused with her behavior, he inquires about her condition, and she responds: "[O]ne's own mind has been a Buddha from beginningless time. By not knowing this, great complications follow from such a small base of error for hundreds of thousands of sentient beings…. Not being able to bear the suffering for so many beings, I cry. And then, I laugh because when this small basis of error is known—when one knows one's own mind—one is freed." Coming from a background of nobility and material wealth, Atisha's realization of value as a freely determined product of perception represents a relative challenge and an alteration of life principles with substantial ontological ramifications.
Upon completing his training for meditations on nothingness and emptiness, Atisha was advised to go study with Avadhutipa, a Vajrayana master. Though Avadhutipa consented to instruct the still young Atisha, he required that the prince first consult the Black Mountain Yogi. The Black Mountain Yogi tested Atisha in numerous ways. First, he cast a lightening bolt in Atisha's direction as he first approached. He then granted the prince thirteen days of instruction, teaching him the Hevajra lineage and bestowing him with the code name Indestructible Wisdom. Finally, the Black Mountain Yogi insisted that before Atisha continue in his studies that he gain permission from his parents to be formally acquitted of royal responsibility, summoning eight naked yogis and yoginis to escort the prince back to Vikramapura.
Returning to the royal palace, Atisha's parents and subjects believed he had gone mad during his jungle refuge. He explained to his parents, however, that his pursuit of Dharma was for the greater benefit of all sentient beings and that "if [he] had become a king [he] would be with [them] only for this life. In future lives [they] would never meet, and this life, for all its luxury and wealth would have been for nothing" . Essentially, Atisha's motivation in renouncing the wealth and luxury in his life was to repay his parents and fellow beings. In understanding his reasons and remembering the religious signs that accompanied the prince's birth, Atisha's mother willingly gave her consent and approved her son's decision to pursue the Dharma. Atisha's father, on the other hand, was much harder to convince and, like the Shakyamuni Buddha's own father, only conceded after multiple requests.
Driven forth by his parent's approval, Atisha went back to Avadhutipa to continue his studies, learning the Madhyamaka middle way and various tantra practices. At one point, he assumed a slight amount of pride in his accomplishments. Such an assumption was immediately met with a reminder that he knew relatively little through the visit from a dakini in a vision. Consequently, Atisha's unnecessary pride was reduced to humbleness overnight and he continued towards the path of enlightenment.
One day, as Atisha considered practicing his tantra with all the energy he could summon until he achieved his full potential he was confronted by a contending voice. The Black Mountain Yogi appeared to him in a dream, and advised him to take his time through steady practice in order to achieve the enlightenment he was seeking. Rather than extend all his powers at once, the Black Mountain Yogi warned, he should endeavor to become a "spiritual seeker who has renounced family life", a monk. Therefore, in his twenty-ninth year, Atisha was formally declared a monk under an ordination of the great Shilarakshita, and given the new name of Dipamkara Srijnana, meaning "He Whose Deep Awareness Acts as a Lamp."
Even as a monk, Dipamkara Srijnana yearned for the fastest and most direct means of attaining perfect enlightenment. He made a pilgrimage to Bodhgaya and, as he was circumambulating the great stupa there, had a vision consisting of two materializations of Tara. One asked the other what the most important practice for attaining enlightenment was, and the other duly replied that "the practice of bodhichitta, supported by loving kindness and great compassion is most important." Atisha thenceforth dedicated himself to refining his understanding and practice of bodhichitta. Thus, at the age of thirty-one, the monk arranged for a perilous journey, traveling for thirteen months to Sumatra in order to study under the reputable Suvarnadvipi Dharmakirti, soemtimes called Dharmarakshita and known in Tibetan as Serlingpa (Wylie:Gser-gling-pa), a supposed master of bodhichitta. Under the guidance of Dharmarakshita, Atisha remained on the island of Sumatra for twelve years studying bodhichitta and exclusive mind training techniques of oral origination. Finally, after over a decade of intensive training, Dharmarakshita advised Atisha to "go to the north. In the north is the Land of Snows." Dharmarakshita was referring to Tibet, a region with a Buddhist tradition forever changed after the arrival of Atisha Dipamkara Srijnana.

[edit] Studies
According to Tibetan sources, Atisha was ordained into the Mahasamghika lineage at the age of twenty-eight by the Abbot Shilarakshita and studied almost all Buddhist and non-Buddhist schools of his time, including teachings from Vishnu, Shiva, Tantric Hinduism and other beliefs. He also studied the sixty-four kinds of art, the art of music and the art of logic and accomplished these studies until the age of twenty-two. Among the many Buddhist lineages he studied, practiced and transmitted the three main lineages were the Lineage of the Profound Action transmitted by Maitreya/Asanga, Vasubandhu, the Lineage of Profound View transmitted by Manjushri/Nagarjuna, Chandrakirti, and the Lineage of Profound Experience transmitted by Vajradhara/Tilopa, Naropa.[3] It is said that Atisha had more than 150 teachers.

[edit] Preaching in Sumatra and Tibet
Before journeying to Tibet, however, Atisha first returned to India. Once back, the increasingly knowledgeable monk received much attention for his teachings and skills in debate and philosophy. On three separate occasions, the monk Atisha was acclaimed for defeating non-Buddhist extremists in debate. When he came into contact with what he perceived to be a misled or deteriorating form of Buddhism he would quickly and effectively implement reforms. Soon enough he was appointed to the position of steward, or abbot, at the venerable Buddhist college Vikramasila, established by the King Dharmapala of Bengal.
Atisha's return from Sumatra and rise to prominence in India coincided with a flourishing of Buddhist culture and the practice of Dharma in the region, and in many ways Atisha's influence contributed to these developments. As Dharmarakshita had predicted, however, Buddhism in Tibet was in desperate need of resuscitation. Some Tibetans, for example, believed that "ethical self-discipline and tantra were mutually exclusive and that enlightenment could be achieved through intoxication and various forms of sexual misconduct." The politically unstable rule of King Langdarma had suppressed Tibetan Buddhism's teachings and persecuted its followers for over seventy years. According to the Blue Annals, new king of the Western Tibetan kingdom of Guge by the name of Lha Lama Yeshe Yod, however, was a strict believer in Dharma and so sent his academic followers to learn and translate some of the Sanskrit Buddhist texts. [4] Among these academics was Nagtso, who was eventually sent to Vikramasila college to study Sanskrit and plead with Atisha to come teach the Dharma in his homeland.
At first, Atisha declined the offer to come reintroduce the Buddha's teachings in Tibet. He believed that he was getting too old for travel and had much unfinished work at the monastic college. On the evening following his declination, however, he received a vision in which his tutelary guide Tara informed him that his trip to Tibet would be very successful: not only would he greatly honor and assist the Tibetans, but he would also find a dedicated disciple and further contribute to the spread of Dharma. In exchange for these benefits, however, he would only live to seventy-two years.
In truth, Atisha's undertaking in Tibet was never in doubt. Prophecies of the impending departure begin with Dharmarakshita in Sumatra and follow Atisha's story up until his vision of Tara. During his travels across the perilous Himalayas, the Tibetan scholar Nagtso "vaguely realized that […] miraculous manifestations assisted me in an uninterrupted flow." Nagtso was referring, whether he knew it or not, to the numerous assistances provided by Avalokitesvara throughout his trip to Vikramasila. As such, it seems as though Atisha's two-year journey to Tibet is interpreted within the Buddhist tradition as a fulfillment of destiny.
Once he arrived, Atisha grasped very quickly the Tibetan peoples’ enthusiasm for the Dharma, but relative lack of comprehension. At Ngari, he was very impressed with the king's request for "a teaching of the people […] had [Atisha] been asked for advanced empowerments into tantric deity systems […] he would have been far less pleased" . It was during the three years Atisha spent in this town that he compiled his teachings into his most influential scholarly work, A Lamp for the Path to Enlightenment, and encountered the disciple forecast by Tara, Dromtonpa.
According to Jamgon Kongtrul, when Atisha discovered the store of Sanskrit texts at Pekar Kordzoling, the library of Samye, "he said that the degree to which the Vajrayana had spread in Tibet was unparalleled, even in India. After saying this, he reverently folded his hands and praised the great dharma kings, translators, and panditas of the previous centuries."[5]

[edit] Death

This section may require cleanup to meet Wikipedia's quality standards.
As he grew old, Atisha moved on from Ngari and accepted an invitation from Dromtonpa to explore Central Tibet. In Nyetang, a town near Lhasa, Atisha spent nine years during which he discovered Tibetan libraries with impressive collections written in both Sanskrit and Tibetan. The venerable monk moved around the region for another five years before passing away in 1052 at the prophesied age of seventy-two. He was enshrined near his last permanent home in the town of Nyetang.
After staying for thirteen years in Tibet, Atisha died in 1052 CE in a village called Lethan, near Lhasa.[6] The site of his last rites at Lethan has turned into a shrine. His ashes were brought to Dhaka, Bangladesh on 28 June 1978 and placed in Dharmarajika Bauddha Vihara.

[edit] Legacy
Atisha remains an important figure in the Tibetan Buddhist tradition for several reasons. First, he refined, systematized, and compiled an innovative and thorough approach to bodhichitta known as "mind training" (Tib. lojong), in such texts as A Lamp for the Path to Enlightenment, and established the primacy of bodhichitta to the Mahayana tradition in Tibet. In this sense, Atisha not only dictated a scholarly model for bodhichitta but acted as a living human example.
Second, after King Langdarma's intolerant reign, the monastic Buddhist tradition of Tibet had been nearly wiped out. Atisha's closest disciple, Dromtönpa, is considered the founder of the Kadam school, which later evolved into the Gelug, one of the four main school of Tibetan Buddhism. Although monasticism and the lojong teachings were of greatest centrality to the Kadam/Gelug, they were incorporated into the other three schools--the Nyingma, Kagyu, Sakya--as well.
Finally, Atisha mobilized his influence in India towards the goal of reforming the impurities and redirecting the development of Buddhism there, in the native country of the Shakayumi Buddha. For these reasons and more, Atisha remains a central figure in the history and religious study of Buddhism.

[edit] Writings
Atisha wrote, translated and edited more than two hundred books, which helped spread Buddhism in Tibet. He discovered several Sanskrit manuscripts in Tibet and copied them himself. He translated many books from Sanskrit to Tibetan. He also wrote several books on Buddhist scriptures, medical science and technical science in Tibetan. Dipamkara wrote several books in Sanskrit, but only their Tibetan translations are extant now. Seventy-nine of his compositions have been preserved in Tibetan translation in the Tengyur (bstan-sgyur). Following are his most notable books:
Bodhi-patha-pradipa or Bodhipathapradīpa (Tib. Byang-chub lam-gyi sgron-ma)
Charya-sanggraha-pradipa
Satya-dvayavatara
Bodhi-sattva-manyavali
Madhyamaka-ratna-pradipa
Mahayana-patha-sadhana-sanggraha
Shiksa-samuchchaya Abhisamya
Prajna-paramita-pindartha-pradipa
Ekavira-sadhana
Vimala-ratna-lekha
Vimalaratnalekha is a Sanskrit letter to Nayapala, king of Magadha. Charyasamgrahapradipa contains some kirtan verses composed by Atisha.

Jagadish Chandra Bose in Royal Institution, London


Description
Sir Jagadish Chandra Bose, CSI, CIE, FRS (Bengali: জগদীশ চন্দ্র বসু Jôgodish Chôndro Boshu) (November 30, 1858–November 23, 1937) was a Bengali polymath: a physicist, biologist, botanist, archaeologist, and writer of science fiction.[1] He pioneered the investigation of radio and microwave optics, made very significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent.[2] He is considered one of the fathers of radio science,[3] and is also considered the father of Bengali science fiction. He was the first from the Indian subcontinent to get a US patent, in 1904.
Born in Bengal during the British Raj, Bose graduated from St. Xavier's College, Calcutta. He then went to the University of London to study medicine, but couldn't complete his studies due to health problems. He returned to India and joined the Presidency College 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 in order to allow others to develop on his research. Subsequently, he made some pioneering discoveries in plant physiology. He used his own invention crescograph to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for patent for one of his inventions due to peer pressure, his reluctance to any form of patenting was well known. Now, some 70 years after his death, he is being recognised for many of his contributions to modern science.
Early life and education
Bose was born in Munshigonj District in Bengal (now in Bangladesh) on November 30, 1858. His father, Bhagawan Chandra Bose, was a Brahmo and leader of the Brahmo Samaj and worked as a deputy magistrate/ assistant commissioner in Faridpur,[4] Bardhaman and other places.[5] His family hailed from the village Rarikhal, Bikrampur, in the current day Munshiganj District of Bangladesh.[6]
Bose’s education started in a vernacular school, because his father believed that one must know one's own mother tongue before beginning English, and that one should know also one's own people.[citation needed] Speaking at the Bikrampur Conference in 1915, Bose said:
“At that time, sending children to English schools was an aristocratic status symbol. In the vernacular school, to which I was sent, the son of the Muslim attendant of my father sat on my right side, and the son of a fisherman sat on my left. They were my playmates. I listened spellbound to their stories of birds, animals and aquatic creatures. Perhaps these stories created in my mind a keen interest in investigating the workings of Nature. When I returned home from school accompanied by my school fellows, my mother welcomed and fed all of us without discrimination. Although she was an orthodox old fashioned lady, she never considered herself guilty of impiety by treating these ‘untouchables’ as her own children. It was because of my childhood friendship with them that I could never feel that there were ‘creatures’ who might be labelled ‘low-caste’. I never realised that there existed a ‘problem’ common to the two communities, Hindus and Muslims.”[5]
Bose joined the Hare School in 1869 and then St. Xavier’s School at Kolkata. In 1875, he passed the Entrance Examination (equivalent to school graduation) of Calcutta University and was admitted to St. Xavier's College, Calcutta. At St. Xavier's, Bose came in contact with Jesuit Father Eugene Lafont, who played a significant role in developing his interest to natural science.[6][5] He received a B.A. in Science from Calcutta University in 1879.[4]
Bose wanted to go to England to compete for the Indian Civil Service. However, his father, a civil servant himself, canceled the plan. He wished his son to be a scholar, who would “rule nobody but himself.”[citation needed] Bose went to England to study Medicine at the University of London. However, he had to quit because of ill health.[7] The odour in the dissection rooms is also said to have exacerbated his illness.[4]
Through the recommendation of Anand Mohan, his brother-in-law (sister's husband) and the first Indian wrangler, he secured admission in Christ's College, Cambridge to study Natural Science. He received the Natural Science Tripos from the University of Cambridge and a BSc from the University of London in 1884. Among Bose’s teachers at Cambridge were Lord Rayleigh, Michael Foster, James Dewar, Francis Darwin, Francis Balfour, and Sidney Vines. At the time when Bose was a student at Cambridge, Prafulla Chandra Roy was a student at Edinburgh. They met in London and became intimate friends.[4][5]

[edit] Joining Presidency College
Bose returned to India in 1885, carrying a letter from Fawcett, the economist to Lord Ripon, Viceroy of India. On Lord Ripon’s request Sir Alfred Croft, the Director of Public Instruction, appointed Bose officiating professor of physics in Presidency College. The principal, C. H. Tawney, protested against the appointment but had to accept it.[8]
Bose was not provided with facilities for research. On the contrary, he was a ‘victim of racialism’ with regard to his salary.[8] In those days, an Indian professor was paid Rs. 200 per month, while his European counterpart received Rs. 300 per month. Since Bose was officiating, he was offered a salary of only Rs. 100 per month.[9] With remarkable sense of self respect and national pride he decided on a new form of protest.[8] Bose refused to accept the salary cheque. In fact, he continued his teaching assignment for three years without accepting any salary.[10] Finally both the Director of Public Instruction and the Principal of the Presidency College fully realised the value of Bose’s skill in teaching and also his lofty character. As a result his appointment was made permanent with retrospective effect. He was given the full salary for the previous three years in lumpsum.[4]
Presidency College lacked a proper laboratory. Bose had to conduct his research in a small 24 square foot room.[4] He devised equipment for the research with the help of one untrained tinsmith.[8] Sister Nivedita wrote, “I was horrified to find the way in which a great worker could be subjected to continuous annoyance and petty difficulties ... The college routine was made as arduous as possible for him, so that he could not have the time he needed for investigation.” After his daily grind, which he of course performed with great conscientiousness, he carried out his research far into the night, in a small room in his college.[8]
Moreover, the policy of the British government for its colonies was not conducive to attempts at original research. Bose spent his hard-earned money for making experimental equipment. Within a decade of his joining Presidency College, he emerged a pioneer in the incipient research field of wireless waves.[8]

[edit] Marriage
In 1887, Bose married Abala, daughter of the renowned Brahmo reformer Durga Mohan Das. Abala was awarded Bengal government scholarship in 1882 to study medicine in Madras (now Chennai), but had to quit because of ill health.[11] At the time of their marriage Bose was in a financial crisis because of his refusal to accept his unequal salary and also because of some debts incurred by his father. The newly married couple faced privations, but managed to survive and eventually repaid the debts of Bose's father. Bose's parents lived for some years after their debts were cleared.[5]

[edit] Radio research
See also: Invention of radio
The British theoretical physicist James Clerk Maxwell mathematically predicted the existence of electromagnetic waves of diverse wavelengths, but he died in 1879 before his prediction was experimentally verified. British physicist Oliver Lodge demonstrated the existence of Maxwell’s waves transmitted along wires in 1887-88. The German physicist Heinrich Hertz showed experimentally, in 1888, the existence of electromagnetic waves in free space. Subsequently, Lodge pursued Hertz’s work and delivered a commemorative lecture in June 1894 (after Hertz’s death) and published it in book form. Lodge’s work caught the attention of scientists in different countries including Bose in India.[12]
The first remarkable aspect of Bose’s follow up microwave research was that he reduced the waves to the millimetre level (about 5 mm wavelength). He realised the disadvantages of long waves for studying their light-like properties.[12]
In 1893, Nikola Tesla demonstrated the first public radio communication.[13] One year later, during a November 1894 (or 1895[12]) public demonstration in Kolkata, Bose ignited gunpowder and rang a bell at a distance using millimetre range wavelength microwaves.[10] Lieutenant Governor Sir William Mackenzie witnessed Bose's demonstration in the Calcutta Town Hall. Bose wrote in a Bengali essay, Adrisya Alok (Invisible Light), “The invisible light can easily pass through brick walls, buildings etc. Therefore, messages can be transmitted by means of it without the mediation of wires.”[12] In Russia, Popov performed similar experiments. In December 1895, Popov's records indicate that he hoped for distant signalling with radio waves.[14]
Bose’s first scientific paper, “On polarisation of electric rays by double-refracting crystals” was communicated to the Asiatic Society of Bengal in May 1895, within a year of Lodge’s paper. His second paper was communicated to the Royal Society of London by Lord Rayleigh in October 1895. In December 1895, the London journal the Electrician (Vol 36) published Bose’s paper, “On a new electro-polariscope”. At that time, the word ‘coherer’, coined by Lodge, was used in the English-speaking world for Hertzian wave receivers or detectors. The Electrician readily commented on Bose’s coherer. (December 1895). The Englishman (18 January 1896) quoted from the Electrician and commented as follows:
”Should Professor Bose succeed in perfecting and patenting his ‘Coherer’, we may in time see the whole system of coast lighting throughout the navigable world revolutionised by a Bengali scientist working single handed in our Presidency College Laboratory.”
Bose planned to “perfect his coherer” but never thought of patenting it.[12]
In May 1897, two years after Bose's public demonstration in Kolkata, Marconi conducted his wireless signalling experiment on Salisbury Plain.[14] Bose went to London on a lecture tour in 1896 and met Marconi, who was conducting wireless experiments for the British post office. In an interview, Bose expressed disinterest in commercial telegraphy and suggested others use his research work. In 1899, Bose announced the development of a "iron-mercury-iron coherer with telephone detector" in a paper presented at the Royal Society, London.[15]
It appears that Bose's demonstration of remote wireless signalling has priority over Marconi.[16] He was the first to use a semiconductor junction to detect radio waves, and he invented various now commonplace microwave components. In 1954, Pearson and Brattain gave priority to Bose for the use of a semi-conducting crystal as a detector of radio waves. Further work at millimetre wavelengths was almost nonexistent for nearly 50 years. In 1897, Bose described to the Royal Institution in London his research carried out in Kolkata at millimetre wavelengths. He used waveguides, horn antennas, dielectric lenses, various polarisers and even semiconductors at frequencies as high as 60 GHz; much of his original equipment is still in existence, now at the Bose Institute in Kolkata. A 1.3 mm multi-beam receiver now in use on the NRAO 12 Metre Telescope, Arizona, U.S.A. incorporates concepts from his original 1897 papers.[14]
Neville Francis Mott, Nobel Laureate in 1977 for his own contributions to solid-state electronics, remarked that "J.C. Bose was at least 60 years ahead of his time" and "In fact, he had anticipated the existence of P-type and N-type semiconductors."

[edit] Plant research
His next contribution to science was in plant physiology. He forwarded a theory for the ascent of sap in plants in 1927, his theory contributed to the vital theory of ascent of sap. According to his theory, electromechanical pulsations of living cells were responsible for the ascent of sap in plants.
He was skeptical about the then, and still now, most popular theory for the ascent of sap, the tension-cohesion theory of Dixon and Joly, first proposed in 1894. The 'CP theory', proposed by Canny in 1995,[17] validates this skepticism. Canny experimentally demonstrated pumping in the living cells in the junction of the endodermis.
In his research in plant stimuli, he showed with the help of his newly invented crescograph that plants responded to various stimuli as if they had nervous systems like that of animals. He therefore found a parallelism between animal and plant tissues. His experiments showed that plants grow faster in pleasant music and its growth retards in noise or harsh sound. This was experimentally verified later on[citation needed].
His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli (wounds, chemical agents) in plants, which were earlier thought to be of chemical in nature. These claims were experimentally proved by Wildon et al. (Nature, 1992, 360, 62–65). He also studied for the first time action of microwaves in plant tissues and corresponding changes in the cell membrane potential, mechanism of effect of seasons in plants, effect of chemical inhibitor on plant stimuli, effect of temperature etc. He claimed that plants can "feel pain, understand affection etc.," from the analysis of the nature of variation of the cell membrane potential of plants, under different circumstances.

[edit] Science fiction
In 1896, Bose wrote Niruddesher Kahini, the first major work in Bangla science fiction. Later, he added the story in the Obbakto book as Polatok Tufan. He was the first science fiction writer in the Bengali language.[18]

[edit] Bose and patents
Bose was not interested in patenting his invention. In his Friday Evening Discourse at the Royal Institution, London, he made public his construction of the coherer. Thus The Electric Engineer expressed "surprise that no secret was at anytime made as to its construction, so that it has been open to all the world to adopt it for practical and possibly moneymaking purposes."[4] Bose declined an offer from a wireless apparatus manufacturer for signing a remunerative agreement. One of Bose's American friends, Sara Chapman Bull, succeeded in persuading him to file a patent application for "detector for electrical disturbances". The application was filed on September 30, 1901 and it was granted on 29 March 1904 as US patent 755840 .
Speaking in New Delhi in August 2006, at a seminar titled Owning the Future: Ideas and Their Role in the Digital Age, Dr. V S Ramamurthy, the Chairman of the Board of Governors of IIT Delhi, stressed the attitude of Bose towards patents:
"His reluctance to any form of patenting is well known. It was contained in his letter to (Indian Nobel laureate) Rabindranath Tagore dated May 17, 1901 from London. It was not that Sir Jagadish was unaware of patents and its advantages. He was the first Indian to get a US Patent (No: 755840) in 1904. And Sir Jagadish was not alone in his avowed reluctance to patenting. Roentgen, Pierre Curie and others also chose the path of no patenting on moral grounds."
Bose also recorded his attitude towards patents in his inaugural lecture at the foundation of the Bose Institute, on November 30, 1917.

[edit] Legacy
Bose’s place in history has now been re-evaluated, and he is credited with the invention of the first wireless detection device and the discovery of millimetre length electromagnetic waves and considered a pioneer in the field of biophysics.
Many of his instruments are still on display and remain largely usable now, over 100 years later. They include various antennas, polarisers, and waveguides, which remain in use in modern forms today.
Commemorating his birth centenary in 1958, the JBNSTS scholarship programme was started in West Bengal.

দীর্ঘদিনের একটি স্বপ্ন, একটি উদ্দীপনা, একটি সুপ্ত ভালোবাসা যাকে আমি ভালোবাসি তার কথা অন্যকে বলতে শুনাতে তাকে নিয়ে কবিতা লিখতে কিন্তু কি করব, তাকে নিয়ে কিছু বলতে গেলে, কিছু লিখতে গেলে তার কাছে যেতে হবে, তার সমন্ধে জানতে হবে তবেই না হয়ে উঠবে কিছু বলা কিছু লিখা। কার কথাই বা বলব মানুষ তো শুধু তিনজনই কেই ভালোবাসতে পারে এক জম্মদাতা, আর যার আশ্রয়ে জম্ম নেওয়া আর যাদের সাথে বড় হয়ে উঠা। আমি আমার আশ্রয় এর কথা বলছি আমার জম্ম ভুমি সোনার বাংলার বিক্রমপুরের কথা।

ভালো বাসি তোমাকে আমি বিক্রমপুর, তোমার দেওয়া ভালোবাসা-পচাপাটের গন্ধ, কৃষকের জমি ভড়া আলু, জমিদারদের জমিদারী উদ্দিপনা, গ্রাম্যবালক বালিকার শুভ্রপেম, শিশুকিশোরদরে মক্তবে ভোর বেলা ছুটে যাওয়া, ভোরের শিশির জড়ে পরার আগে খেজুরের রস আহরন করা, ছানা দধিওযার হাকানি, হাটবাজার সরগম, বুড়ো দাদীর হুক্কা হাকানীর শব্দ আর মিষ্টি পানের ঠোট লাল করে রসিকতা করা, বর কনের বিয়ের সরবরে দলবেধে পাড়া বধুদের গীত গাওয়া, পরন্ত বিকেলে কাচা মাটির পথ হয়ে নব বধুকে নিয়ে পালকীওলার গীত আর দুরন্ত ছেলের সাজের বেলা পড়ন্ত বিকেলের ঘুড়ি উড়ানোর দৃশ্য, বষার অথৈই পানিতে এক ঝাক হার্সের সাতারঁ কাটা, মাথায় গামছা বেধে জেলের মাছ ধরা কোন স্মৃতিইযেন ভুলিতে পারিনা। তাই সুন্দর বিক্রমপুরকে জানার আশায় আমি হন্য ঘুরতে শুরু করলাম বিভিন্ন জ্ঞানীগুনিজনদের কাছে কিন্তু বিধিরাম কেহ আমায় তেমন করে কিছু বলতে বা দিতে পারলনা। সেই থেকে মনকে বুঝালাম বিক্রমপুরকে নিয়ে জানতে হলে এত কষ্ট করে বিভিন্ন বই সংগ্রহ করে সবার পক্ষে এটা করা সম্ভব নয়, সেই চিন্তা থেকে মনে আসল বিক্রমপুরের বই সংগ্রহ করে একটি লাইব্রেরী করব। যদিও বিক্রমপুরের উপরের অনেক জায়গাতেই লাইবেরী ছিল কিন্তু ইচ্ছা করলেও পড়ারমত সুযোগ সুবিধা ছিল না।






সেই চিন্তা থেকেই আমি বিক্রমপুরের উপর বিভিন্ন তথ্য সংগ্রহ করতে শুরু করলাম সবাই যাতে বিক্রমপুর সমন্ধে জানতে পারে সেই লক্ষে, -কিন্তু সেটা কিকরে সম্ভব আমার পক্ষে তখন এতবড় একটা বিষয় নিয়ে বই ছাপানো বা বিক্রমপুরের ইতিহাস এতই বিস্তৃত যে, একটা বইতে তা ছাপিয়ে বিক্রমপুরের পূর্ণতা আনা যায় না। তাই এই চিন্তায় আমি অস্থির হয়ে উঠলাম- আমি তখন পড়াশোনা করছি মাত্র হাই স্কুলে কিন্তু তখন আমি কম্পিউটার নিয়ে টুকটাক চিন্তা করি এবং ১৯৯০ সালে আমি কম্পিউটারের উপড়ে কিছু এপ্লিকেশন কোর্স সম্পন্ন করে পড়াশোনার পাশাপাশি কাজ করি। যখন আমি মাল্টিমিডিযার উপর পড়াশোনা করি তখনই আমি ধারণা লাভ করি যেকোন তথ্য সংরক্ষণ করার জন্য এখন শুধু কাগজই এক মাত্র মাধ্যম নয় আরও মাধ্যম আছে সেটা হচ্ছে ডিজিটাল মিডিয়া সেই থেকে আমার স্বপ্ন বাস্তবায়নের দাড়েঁতে শুরু করল ততক্ষনে আমি মাল্টিমিডিয়ার উপরে পড়াশোনা শেষ করে কম্পিউটার সফ্টওয়্যার ইঞ্জিনিয়ার হিসাবে পড়াশোনা শুরু করেছি। এখানে বলে রাখা ভালো আমার ছাত্রজীবন বয়স থেকেই আমি কম্পিউটারের উপর প্রশিক্ষক হিসাবে প্রশিক্ষণ দিতাম।


যখনই আমি বিক্রমপুর নিয়ে ওয়েব সাইট করার চিন্তা করলাম সেইলাম ঠিক সেই মূহুতেই আমি পাশাপাশি কম্পিউটার ট্রেনিং ইন্সিটিটিউট প্রতিষ্ঠা করি। বিভিন্ন জায়গায় ঘুরে ঘুরে বই সংগ্রহ করি আর নিজেই বিক্রমপুরের উপরে ফটোগ্রাফি করি আর কম্পিউটারে সেগুলি সংরক্ষণ করি । সেই দীর্ঘ আট দশ বছরের সাধনার পর আমি প্রায় ১৫/২০টি বই সরাসরা কম্পিটারের সংরক্ষন করে আপনাদের জন্য একটি বিক্রমপুরের উপর ওয়েব সাইট প্রকাশ করি আপনাদের বিক্রমপুর সমন্ধে জানার সুবিধার্থে, এজন্য অবশ্য আমি যারা আমাকে বিভিন্ন বই এর সন্ধান দিয়েছে এবং বিভিন্ন ধরনের তথ্য দিয়েছে আর আমি এই ৫০০/১০০০ পৃষ্ঠার বই কম্পিউটারের টাইপ করে সংরক্ষন করেছি।




এই ওয়েভ সাইটটি নিয়ে আমি এখনো কাজ করছি কিভাবে এটিকে একটি ডাইনামিক ওয়েব পোর্টাল তৈরি করা যায়। অবশ্য পুর্ণাংগভাবে তৈরির শেষ পযায়।
