PRIME NUMBERS

If you get lost as to the article in question for audio, look here. In Our Time


For one's listening pleasure. It's really very good. Do you have a Pure love for Math?


Have you figured Riemann's Hypothesis out yet?It's worth a Million.

a team of researchers in Missouri successfully calculated the highest prime number - it has 9.1 million digits.
emphasis added.

I wince everytime I see that - it's the highest known prime, not the highest prime.

I have a truly marvellous proof of the Riemann Hypothesis which this thread is too small to contain.

I know its great, but why does anybody care?
Whats the big deal about prime numbers?
When I worked in the feed mill, my boss could combine 5 or 6 raw materials to make an animal feed with, say, 15% protein and 4% fat and all the different minerals in good proportion and an optimum price in about 10 minutes.
He didnt even use a calculator. He used matrix math and did it out on paper.
You try it on a calculator, and it takes hours!
Then there was the physicist who dropped some leaves from his hand to figure out quickly the
power of one of the first testing nuclear explosions. The shock wave from it ment they didnt go straight down. And he was really close to the result from the instruments.
I think that practical real life stuff like that is more interesting than new prime numbers.

Makes you wonder how mathematics would have been changed if they'd had bigger margins a few centuries ago ...

Brian - often trying to prove math theories do lead to all kinds of practical applications. I don't know if that is necessarily true in the case of the prime number which may be more of a "parlour game"

The pursuit of pure knowledge is valid even if the practical applications seem elusive. Saying abstract math has no practical purpose is equivalent to saying that art has no practical purpose. They both fulfill the same purpose: exercise humanity's most creative minds, leaving legacies for the rest of us to admire, to motivate and to persist.

It's actually a good question in regards to the value it would have to someone who works their lives in a mill, or, is a news paper reporter.

If one did not have a love for computer information processing that goes on around us, I think it would have little value.

Let's say You encounter a complex emotive situation that has been most troubling to your mates and you.

You look for a underlying ways to resolve this, mathematically given certain parameters you are all encountering, to have defined a most approriate response to this, that happens, becuase of this?

But if you took these lessons to heart, and moved them within the society in which we live as simple people, how could certain actions effect let's say a "negotiating process" or a economist's view on the dynamics taking place in trade deficits and such?

While our views are govern by the socialbility of our encounters and such, then it would not be so strange to consider that the engineering chemically, mechanically, or electrically would define aspects of such manufacturing processes, while we deal with mental and social issues because of that problem above.

Without the math, science might not have progressed along side of the physics? Or the physics the math?

You might have heard of the fairy tales of Alice and Mirror World. Sometimes such simple stories have a more profound effect, when held to the lessons that we will learn about the strange math?

In regards to art, sometimes mathematicians even though they seem to be very logical as their math dictates, some of them might have problems seeing what they are doing or might employ an artist to help create the visualization of the math being developed.

A case in point might be Penrose with Escher and the tessellations.

For somemore listening enjoyment.

Hey! What about my contribution to pure math?
60% supermajoritys requirements for referenda violates one person one vote.
(It makes 40 votes for one choice equal to 60 votes for another therefore it gives anyone in the 40 grouping 1.5 votes). Which is unfair and undemocratic.
I think it is more important than some computer finding an unimaginable number.
Would any of the learned gentlemen like to investigate that little violation of democratic relativity?
Think about how mathematically lazy we have become.
That little trick got by 4 million people (including me) in BC and the people of pei last year without anybody destroying the whole 60% supermajority nonsence in that straight mathematical way.
Could it be we were too busy looking for prime numbers to notice the blatant denial of our democratic rights?

That was Enrico Fermi, with some bits of paper. He's famous in physics for that kind of order-of-magnitude math. For this reason, such problems where the question does not include all the information needed to arrive at the answer, and for which valid, if necessarily imprecise, assumptions need to be made, are called "Fermi Questions."

A classic example is the one where you guess how many piano tuners there are in a fairly large city. Almost any valid assumption set (so many households, so many pianos in a certain percentage of households, and so on) leads to approximately 50-100 tuners, and the phone book nearly always hits the right order of magnitude.

For the math geeks, this describes the Riemann Zeta Function and this describes the Riemann Hypothesis and various attempts to prove it.

oops I think I was busy tryng to stave off american companies from taking over Canadians resources. Wonder why the federal government didn't intercede, on behalf of Canadians, while they now turn our heads to the wheat board, an dinstigate fears. PC's and Liberals are captialists in disguise.


oh no! for you Geek types, Dr. Conway, this is it

Unfortunately this thread has failed to differentiate between prime numbers and irreducible numbers. The two are not the same!(I got that one pounded through my head in an undergraduate number theory course.) It doesn't matter if you're talking about the Natural Numbers since the two definitions are equivalent there but does matter elsewhere.

Unfortunately abnormal, your link did not seem to load at 62 pages.

If you are not tired of hearing music, then listen to this.

And if you like "art in math" check this out.

Who needed a mathematician to figure out that a 60% supermajority requirement is undemocratic?

observer,

I tried my link from the office as well as my home machine - works fine although it does take a couple of minutes after it says it's done to finish (and that's over the pipes we have in the office, no wimpy DSL lines).

More to the point, there is a math prof at that has published what he claims is a proof of the Riemann Hypothesis. To date no-one has proven him wrong but his track record has been spotty so no-one takes him seriously. [As an aside, when I was a graduate student one of the guys I shared an office with had a solution to the Reimann Hypothesis. The entire department, students, faculty, etc., spent weeks trying to figure out where he went wrong. The answer turned out to be simple. A classic theorem in one of the standard references was wrong.]

I'll try again later.

I think what is significant that if you go back in history and look a what Gauss and Riemann were doing, how they changed the way we see, I would think you would try and hold this in context of that information.

Of course speculation on my part, and just one more view to the parlour trick? Non!

Now when you think of Pascal and the Fibonacci numbers emerge, you have to wonder, how this framework, would ever allowed us to see in nature, the representation these numbers have for us.

Do you understand this? That's the interesting thing about how mathematics emerges. Pascal framework and probability statistics? Why these particluar numbers?

So you need a framework in which to hold this Hypothesis, and if held in context would you have found valuation in how you see Gaussian coordinates? UV interpretation would have varied and the primes, "this length" and valuation of that line, can indeed vary too. That is part of the perception shared, that Gauss and Riemann were instrumental in.

Would you agree?

Sorry for going on so long. It really is interesting to me, and I look at these underlying factors what ever the circumstance in society or science. Problems within our everyday lives.

That's the pure thought I am after, yet I would fail miserably in all the countless math structures used. So I study.

Louis de Branges is a rather interesting character. He's published what he claims is a proof of the Riemann Hypothesis. Unfortunately he's known to be a bit of a "character" that has published incorrect proofs in the past. Add to that the fact that he apparently rubs people the wrong way and end result is no-one really listens.

However, you can find links on the site above (click on papers) to both the proof (which I'll be the first to admit is beyond me, at least this far out of grad school/post doc work). However, there is an extremely elegant apology for the proof of the Riemann hypothesis on the site as well. That's well worth reading.

Is he right? Who knows. But it is at least possible that the solution to one of the most important mathematical problems out there won't be read because nobocy likes the author.

Interesting.

APOLOGY FOR THE PROOF OF THE RIEMANN HYPOTHESIS by Louis de Branges

The resulting confusion hinders an understanding of the meaning of the Riemann hypothesis. Although the Riemann hypothesis gives information about prime numbers, the significance of the conjecture lies in the application of properties of numbers to the symmetries of objects in space.
