Happy birthday. There's a fun birthday game you should all play. It's called "Kill someone for every year old you are" Yeah, so if you're 21, you kill 21 people. It's fun...

Thank You

And Very 21

Jesus, were those caps?

Happy Birthday and good luck with your head in the morn.

And Happy Birthday to sKratch too... even though twenty is just basically a countdown year.

pssst... question.

How do I calculate <x> if <x>=int(Ψ^*Ψdx) if Ψ = A*exp(-(x-x0)^2/(2*a^2))exp(i*p0*x)/h-bar) and Ψ^* is the complex conjugate of Ψ?

omg you do that sKratch? That's some heavy shit.

10-24-2005, 09:34 AM

Mmmm... well Ψ^*Ψ = w(x) = A^*A(exp(-(x-x0)^2/a^2), which through unit normalization is 1/(a(sqrt(pi))*exp(-(x-x0)^2/a^2)

so the integral becomes int(1/(a(sqrt(pi))*exp(-(x-x0)^2/a^2)dx)

We then let x-x0 = y, dy=dx, r=1/a so we have:

r/sqrt(pi)*exp(-y^2*r^2)dy, which is a gaussian integral. We must change the bounds from -inf..inf to 0..inf and multiply by 2 to use the integration table, and we get r/sqrt(pi)*(sqrt(pi)/2r)*2 = 1. I should get <x> = x though =/**

** I was missing an "x" multiplication term; <x>=int(Ψ^*Ψ*xdx)

So:

By letting x-x0 = y, x=y+x0

So we have the integral:

r/sqrt(pi)*(y+x0)exp(-y^2r^2)dy which can be rewritten as a sum of two integrals by distributing y+x0:

r/sqrt(pi)*x0*exp(-y^2r^2)dy + r/sqrt(pi)*y*exp(-y^2r^2)dy which gives:

x0 + r/sqrt(pi)*1/(2r^2) = x0 + 1/2r. However, I need the answer "x0". Where did I go wrong?

It is a fancy way of getting your hair permed but it is healthier and better for your hair and alot more expensive. It also sometimes lasts longer. It is called a yuko if you want the non plural noun of it.
