i also wanted to add, if you spin the ship fast enough, you stick to the walls
-
no, but that's because gravity counter acts the effect. yeah i understand, i was wrong, force doesn't necessarily require energy, but we should clearly indicate when force is being applied
-
no its velocity, you can experience this with your car, when you turn your thrown to the side some. clearly force is being applied.

so, i used to have a beef with newton. i thought that an orbiting body should require the expenditure of anergy. with the strong nonclear force i can understand not requiring energy, there's no motion and therefore no change in velocity and therefore no acceleration and therefore no force. but with an orbiting body there's change in velocity, a change in direction, therefore force, and force should require the expenditure of energy. but then i envisioned a pole with one end of rope tied to a pole and the other end tied to a rock, if you put the rock "into orbit" around the pole, yes the rope is applying force, but i see no reason discounting friction it can't obit indefinitely. clearly not all force requires energy expenditure.

Cool Instant Factorising Trick On Two Multiplied Prime Numbers.
phillip1882 replied to olvin dsouza's topic in Mathematics
hmmm. lets say n is 7, 72 × 1 + 36, = 108 72 × 2 + 36 = 180 72 × 3 +36 =252 72 x 4 +36 = 324 72 x 5 +36 = 396 72 x 6 +36 =468 72 x 7 +36 =540 adding all of them together, i get 2268. I'm not sure where the +35 is coming from, but lets add that as well, 2303 from here, how would you determine p and q? -
according to euler, the infinite series 1+2+3+4+5.... = -1/12. the "proof" is a bit complex, but basically revovles around letting the series 1-1+1-1+1-1 = 1/2 here's my problem with this. let S = 1 +1/2 +1/3 +1/4 +1/5 +1/6 ... multiply S by 2. 2*S = 2 +1 +2/3 +1/2 ++2/5 +1/3 ... subtract S 2*S -S = 2 + 2/3 +2/5 +2/7 +2/9 ... subtract S again 2*S -S -S = 1 +2/3 -1/2 +2/5 -1/3 +2/7 -1/4 +2/9 -1/5 0 = 1 +1/6 +1/15 +1//28 +1/45... which aproaches a finite value greater than 0.

there are already 5 dan cpus but making a 9 dan one would be quite hard

this is a cool idea i found over at xkcd forums. for a number n, if n is composite, break it into its prime factors. if n is prime, place '<' '>' around the number and determine the n'th prime its is. then the first 20 numbers are... 1 <> 2 <<>> 3 <><> 4 <<<>>> 5 <><<>> 6 <<><>> 7 <><><> 8 <<>><<>> 9 <><<<>>> 10 <<<<>>>> 11 <><><<>> 12 <<><<>>> 13 <><<><>> 14 <<>><<<>>> 15 <><><><> 16 <<<><>>> 17 <><<>><<>> 18 <<><><>> 19 <><><<<>>> 20 a symmetric number is a number that can be written symmetric about the middle. the first few are 1 <> 2 <<>> 3 <><> 4 <<<>>> 5 <<><>> 7 <><><> 8 <<>><<>> 9 <<<<>>>> 11 <><<>><> 12 <><><><> 16 <<<><>>> 17 <<>><><<>> 18 <<><><>> 19 <><<<>>><> 20 <<<>><<>>> 23 <<<>>><<<>>> 25 <<>><<>><<>> 27 <><<><>><> 28 <<<<<>>>>> 31 <><><><><> 32 <><<>><<>><> 36 <<><<>><>> 37 hypothesis: 1) numbers that differ by true value of 1 won't differ by number of backets by more than 2. 2) symmetric numbers follow a logrithmic growth rate similar to the primes. 3) there is no general algorithm for adding recursive numbers.

I ask this in the most serious way possible: what drugs are you taking? nothing that hasnt been perscribed to me. i've taken abilify to combat some earller bipolarism. i'm currently on some medication to fight any voices which i seem to now sometimes hear since atempting suicide. the medications im on are ripisadol a divaporeox. the reson i bielve in the supernatural is it seems to be not just me but things outside myself acting oddly as well. such as people know things about me that i didnt tell anyone, or people acting in a bizzare manner.

so here is a small list of some of the experainces i had. when i went into the hospital, there were two weman there who i had never met who seemed to know exactly why i was there. one seemed to want to help me the other to condem me. after i got out, in the morning i woke up, my whole body seemed full of light. i dont know how else to describe it other than that. lightr radiated through out my skin. i read the bible and it said my word was truth. i condemned the world by saying one lie, one cheat, one steal is worth a pushment of hell. i went online and people were begging to be realased on a chat sever i regularly visit. i freed everyone, by freeing the worst person, krossos, who i later remembered from a book i read a long time ago is the god of death and destruction. he struck deals with people for their release. he had aparently had aleady been freed 7 times. the bible continued to communicate with me. jesus said he was the true god of isreal and that i should know that becuase he sent me two helpers. after a couple months i experanced a sort of 4th dimential reality. seasons shifted rapidlty, flowers grew and wilted in rapid succession, people scrabled for basic food. shortly after, i had a sensation of my head dissolving in acid, after it was over, i read the bible and the apostle paul said i was sentanced to satan to atone. a tv repairman came to my house to install direct tv. after he was done, i said, i leave you to your work, then he said in a near panic, "no your good your good." then he ran up stair, ran back down stairs, and stepped on my toe. he said i didnt step on oyur toe did i, and i said no as a way of forgiving him. then he said your running the show now. then the television seemed to be commucating with me in a simalar fashion as the bible. i read the bible and it said that i was satan, but that satan cant spit in his own eye. so i spit in my own eye to end it. there's more to it, but just to give you a general idea.

so, let's start from the beginning. the harmonic series: 1/1 +1/2 +1/3 +1/4 ... grows indefinitely. however the series 1/1 +1/2^2 +1/3^2 +1/4^2 etc. aproaches a value, specifically pi/6 (or was it pi^2/6? well the point is its finite) in general 1/2^s +1/3^s +1/4^s ... aproaches an interesting value (something in terms of pi.) whenever s is even. now if we modify the equation in a few ways: first well do 1- each term. 1- 1/2^s +1-1/3^s +1-1/4^s... then we'll take the reciprical of each term. 1/(1-1/2^s) +1/(1-1/3^s) +1/(1-1/4^s)... then we'll multiply rather than add. 1/(1-1/2^s)*1/(1-1/3^s)*1/(1-1/4^s)... and finnally we'l exclude any non prime power terms. 1/(1-1/2^s)*1/(1-1/3^s)*1/(1-1/5^s)*1/(1-1/7^s)... it turns out this is exaclty equvalent to our original equation 1/1 +1/2^s +1/3^s... (its possible to prove this but admittedly i don't know how, im not expert. although this looks ugly, this multiplication means that if we can get the right side to be non-trivally zero we have information we can use to estimate the gap between primes. all trival zero occur whenever s is even. all non-trivail zeros occur when s = a +1/2*sqrt(-1) where a is some unkown value. or at least this is the hypothesis, its never been proven.

so, on my 31'st birthday i tried to commit suicide. i survived, but after which over the course of the next 3 months i had a bizzare set of experances, that let me to believe that there is a supernatural element to the universe. i can't prove this of couse, all i have is alot of allegation about my experiances, but it is enough to make me believe. i chose christainty admitedy becuase it's what i grew up with. had i beem born in the middle east i'd probalby would consider myself muslim. but regardless, i truly believe that there is an element beyond what science can explain.

Permutation combinations that will be possible
phillip1882 replied to mathy_math's topic in Mathematics
if the number of paths at each split is fixed, then the general equation is... r^(n+1) -r ------------- +1 r -1 if not then I'm afraid you'll just have to add. lets say number of paths at each split is 5 and you have 4 levels. 5^(4+1)-5 -------------- + 1 = 781 5-1 -
it doesn't matter, so long as all cases are covered.
