Talk:The Sand Reckoner
From Wikipedia, the free encyclopedia
In Names of large numbers it is said that a myriad is 108 however in this article it is said a myriad is 10,000. Which is correct? Answer: The Names of large numbers page actually says that a myriad myriads is 108, consistent with the statement here that a myriad is 104 (i.e. 10000). Niels Ø 00:41, Nov 29, 2004 (UTC)
I missed that, thanks.
[edit] Accuracy?
- The resulting estimate is that the radius of the universe is about one light year which is consistent with current estimates for the radius of the solar system. Archimedes' final estimate gives an upper bound of 1064 for the number of grains of sand in a filled universe.
It would be interesting to have an estimate of the actual number of grains that would fit in a one-light-year universe. — Johan the Ghost seance 04:55, 26 August 2006 (UTC)
