It's hard to understand what exactly he fixed as most of the words are in Nepali. Most of us here understand conversational Nepali, but literary Nepali is a little tough.

Anyway, it sounds like he found an "error" or "incompleteness" in displacement theorem. If this is the same theorem as rajeshHamal above quoted (s = ut +(1/2) at^2), then nobody claimed there is an error or incompleteness in this equation. If Mr. Kunwar thinks this is wrong, how does he explain the fact that we sent spaceships and landed precisely in the moon, positioned our satellites in the exact location, with the help of this very equation?

Wish somebody posted his paper in english.
