| Permutation Question | 31 Aug 2007 22:47 GMT | 4 |
I have recently been playing with some problems in Hamming's, The Art of Probability. I'm having difficulty understanding two of the solved problems and would appreciate any walkthrough to the solution. Question 1: on page 47 question 2.2-14 reads: "Using all the letters

| MathPuzzle 192: Pizzas | 31 Aug 2007 15:52 GMT | 1 |
GOOD EVENING! Puzzle 192 is about odd sized pizzas. Once again a geometry problem, but a lot simpler than last weeks puzzle. Nevertheless I hope it is to your liking. Don't hesitate to send me your solution.

| JSH: Mathematical intuition, surrogate factoring equations | 31 Aug 2007 02:56 GMT | 17 |
Having come off a tremendous research effort that has given key answers to important questions with surrogate factoring, I find myself still curious about the math world's ability to ignore a factoring idea that has many indications that it should be possible to get it to

I would like to implement logarithmic fading instead of linear in my sound code but I do not know how to go about it. Here is the linear solution, can anyone please suggest a logarithmic replacement? thanks m_currentGain = m_beginGain + ( ( elapsedFadeTime / m_fadeDuration ) * (

I finally am getting a handle on a crucial metric for determining how likely you are to factor using what I call surrogate factoring where if your target composite to factor is T, the following equations x^2 = y^2 mod T

| JSH: Surrogate factoring analysis, done? | 25 Aug 2007 16:13 GMT | 15 |
After my failure with what I deluded myself into thinking (for a while) was the perfect factoring algorithm, I just bit the bullet and began the detailed and tedious analysis that my latest insight indicated which took me into the calculus which was kind of fun, and a

| JSH: Musing on failure | 22 Aug 2007 23:09 GMT | 28 |
Yesterday I started with a long and detailed post talking about the latest insight with my factoring research, but after that post I had several more claiming that I had now solved the factoring problem which all were flawed.

| JSH: Looking back, wondering | 20 Aug 2007 23:25 GMT | 13 |
Wow, I didn't know the solution to the factoring problem would turn out to be that simple. It seems strange to think back over the years since I first started looking at factoring one number by using another and consider all the

| JSH: Perfect factoring algorithm | 20 Aug 2007 19:01 GMT | 22 |
Algorithm for guaranteeing the factorization of a target composite T of any size. Use (x+k)^2 = y^2 + 2k^2 + n*T. 1. Pick k=2 and an n that gives you an absolute value of 2k^2 + n*T

| the mysterious number 153 | 20 Aug 2007 06:51 GMT | 26 |
While changing channels today I heard a preacher talk about the significance of the number 153 in the Bible chapter John 21 (I changed channels before he got around to explaining it). A Google search on "153 "John 21"" produces, among other sites:

I am trying to calculate Pg, the odds that Player A will win a game in tennis against Player B, given Pp = probability that A will win any single point (on average). I am treating all points as equal for the moment.

| JSH: Factoring integers, more analysis | 19 Aug 2007 17:23 GMT | 28 |
ON August 9th I stepped through integer factorization equations in my post "JSH: On integer factorization" and earlier today I thought some more about when that approach might work to give a non-trivial factorization.

After the explanation of my current factoring research that I just posted I realized that wrapped up in this latest analysis is solution to the factoring problem. It's fairly easy but as usual I'll post what I think it is to see if I

| Vectors | 19 Aug 2007 15:24 GMT | 4 |
Can someone please solve this for me I need whole procedure not just the final solution: a, b and c are vectors. c is linear dependent on a+b. In other words c = x (a+b) where x is real number.

Here's a post to go over the latest with my factoring research and explain a key breakthrough, as well as address the issue of demonstration. First some background, since August of last year I have focused on
