Binary Numbers
(Computers)
 The
concept of binary numbers used by
computers for all calculations existed in
Hindu scriptures thousands of years
ago. A number in binary format is either
1 (it exists) or 0 (it does not exist). All
numbers are combinations of 1 and 0.
Our Upanishads say, "all creation is
combination of existence (1) or
nonexistence (0)".

Ayurveda

Our present knowledge of the nervous
system fits in so accurately with the
internal description of the human body
given in the Vedas (5000 years ago).
Then the question arises whether the
Vedas are really religious books or
books on anatomy of the nervous
system and medicine.
