As I heard a speech about science in Hindusim yesterday, I wish other people get a brief introduction about this great ancient Indian culture and know how much it is related to science. If you are interested to know about new things, you will realize that science. This is not a religion, a scientific way of living without disturbing the nature. With my very basic knowledge I understand that there is that much amazing scientific facts behind each of the traditions in Hinduism. I am also not aware of hundreds of scientific facts behind these traditions. I hope discussing or listing some of them will be quiet useful for the users who commit to Hinduism.
