Other figures have been considered to be part of the renaissance. Swami Vivekananda is considered a key figure in the introduction of Vedanta and Yoga in Europe and America and is credited with raising interfaith awareness, and bringing Hinduism to the status of a world religion during the 1800s. Jagadish Chandra Bose was a Bengali polymath: a physicist, biologist, botanist, archaeologist, and writer of science fiction who 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. He is considered one of the fathers of radio science, and is also considered the father of Bengali science fiction. Satyendra Nath Bose was a Bengali physicist, specialising in mathematical physics. He is best known for his work on quantum mechanics in the early 1920s, providing the foundation for Bose–Einstein statistics and the theory of the Bose–Einstein condensate. He is honoured as the namesake of the boson.
