I have a theory that matter and energy are at two opposite ends of a continuum and that accelerating matter changes it into energy while matter, when slowed down sufficiently, assuming it is possible, will become matter.

I recently saw an article that talks about David Norman's book "Introduction to Geogaphy" and it's unbelievable. This textbook says awful things!! It says that a suppose foundation named FINRAF is taking the Amazon as a United States property, which is so wrong. Also it missrespect badly Latin American countries, talking about Bolivia, Venezuela, Suriname, Guyana, Brasil, French Guyana, Colombia and Peru as the poorest and most miserable countries in the world. It also says that they are primitive and unknown and I can continue and continue writing about terrble facts in this schoolar book. Im so mad at this!!! Is all of this true??

I've heard every opinion from people of various qualifications including it doesn't matter, only when it's ~99% dead, if you let it die completely it'll never hold the same maximum charge. Perhaps the answer is different for different types of batteries.

1) I have been working with these kind of polynomials

x^2n + x^n + 1

and I realised that they are a multiple of x^2 + x + 1 but for the cases when n is a multiple of 3.

Adding and substracting x^n, I get:

x^2n + 2 x^n + 1 - x^n = (x^n +1)^2 - x^n

And, if n is an even number, n/2 is a natural number, so, I can factore the expression this way:

[x^n + 1 - x^(n/2)][x^n + 1 + x^(n/2)]

But I cant do this if n is an odd number, since I wouldnt get polynomials factors. But, dividing the original polynomial by x^2 + x + 1, I have noticed that the residual is 0 if n is not a multiple of 3. Any suggestions?

2) In these cases:

x^2n - x^n + 1, adding and substracting 3x^n, I get:

x^2n + 2 x^n + 1 - 3x^n = (x^n +1)^2 - 3x^n

And, if n is an even number, n/2 is a natural number, so, I can factore the expression this way:

[x^n + 1 - V3 x^(n/2)][x^n + 1 + V3 x^(n/2)]

Id like suggestions too for n an odd number

Thanks.

My charger plug and radio plug remain warm even if my mobile is already fully charged or my radio not in use. So why are they leaking energy?

This reminds me of the directive I once heard that you should switch off at the wall and unplug things before going abroad (and I know of people who do this overnight even). Do you really need to unplug, or is switching off at the wall enough?

WHAT WOULD YOU DO IF YOU LEARNED THAT ALMOST
EVERYTHING YOU HAVE BEEN TOLD ABOUT MUSLIM
TERRORISM OVER THE LAST 6 YEARS, WERE ALL LIES?

Why don't you do your own independent research to find out
the REAL truth?

You have been told to fight in a war on terror - this is a LIFE &
DEATH MATTER! Don't you owe it to yourself, to check that
what you are being told is really 100% correct, 100% true,
100% accurate and consistent with the real FACTS? (and not
just some neo-con war monger's opinion?)

FACTS:

Melting point of steel = 1532 C
(molten steel was filmed dripping out of the South Tower)

Jet fuel fire temperature in still air = 233-250 C
(use a pyrometer for proof)

Are there even kites in the NE of america, and are they even water birds in the first place?

Ive gone through all sorts of sea egals, gulls, really all the raptors i can think of. I just happened upon photo's of kites and the shape looked just like that.

White belly, slender sea-bird like wings, about three or four foot span, i think a brownish-greyish feathers, NO flight feathers at the tips of the wings, its very clean and pointy.

ANY IDEAS?

This is the fourth time ive seen this thing.

Iam in upstate NY.
