Much better then the textual post you made at first, I can read this Some interesting discoveries. Do you have the definition of sleep? The 23 chromosomes is also interesting, thats an extremely old reference 5500 bce, 7500 years ago. Perhaps i'm misreading this, do the ancient references refer to the time when it was made first discovered and the modern refers to when it was re-discovered? When were the first written books written in india?
THe first written book dates back to the Ramayana (even before, i dont know) lol Much more on physics Source: http://www.newsfeeds.com/archive/soc-culture-bengali/msg06376.html
