Is there a formula for finding prime numbers that doesnt require brute force?

This thread causes me to digress and ask the question...

Consider if all the matter/mass (anyone know what that is) in the universe where utilized to create a networked supercomputer whose architecture was on an atomic scale, what would that maximum number that computer could handle? and what would the maximum number of calculations a second that computer could do? And what would be necessary to make that computer conscious of itself, and to know the position of every electron or atom in the universe at any given period in time?

Thanks

the answer to your question re:formula for prime nos. is in the post above yours.

their is no formula for finding primes:they have only the approximation of how many primes there are upto any given no. (in the formula given)

as i stated the consequence of solving the

Riemann hypothesis
will make it much easier to find prime nos. (but remember it is the

Holy Grail of maths & may not be solved for a century according to experts in the field)

however i was slightly incorrect in stating that the hypothesis will allow you to find these huge primes

exactly.

what it will actually do is allow you to narrow the search field - i.e. it will tell you how many primes exist in a certain no. range

exactly - if for instance you are looking in the no. range 1^100 to 1^101,the solved riemann hypothesis will tell you how many primes there are in that range,thus aiding your search.

however it is possible that the solved hypothesis may actually allow

predictions of primes,but you will have to ask a qualified mathematician about this(this is a hobby)

as for your question about the computer size required to know about every atom in the universe,logic will tell us that unfortunately, the size of the computer memory required has to be equal to the size of the universe that you wish to record (at the very least),so the maximum size of the universe recordable is 1/2 the universe,which will require a computer memory comprising of the other 1/2 of the universe.

the explanation for this is that for every atom you wish to record,the lowest level of feasible recording for it on a hard-drive would have to be another atom - & a 1:1 ratio is the ultimate correlation you can achieve (more likely you may need something in 1:2 or 1:3 ratios - i.e. 1/3 of the universe to record would require a hard-drive of 2/3 of the universe)

i hope this helps

& to think i only chanced upon this site trying to find out if someone could tell me what kind of money i could make from a sports "calculator" site (as you can see i try to keep my maths thorough) - no one seems to be able to help me with that

ballpark figure?
