can anyone give me any information on some good books, online books or lecture notes to help me with university introductory cosmology
i have my lecture notes but they are very poor and i find it difficult reading and interpreting what is going on
thanks
Explaining your reasoning, show that the ratio of the specifc heat is
CP/CV = (DP/DV)s / (DP/DV)t
hint :use TDS EQUATIONS
I have used tds equation 3 and tds equation 1 and equated them,but i am stuck because i get to an equation like
(CP/CV-1)(DT/DV)p = T(DP/DT)v and just do not...
can anyone help me interpret what exactly this question is asking as i am quite unawares
By direct substitution into the heat equation and calculation of boundary values,
verify that the solution u(x, t) for a metal rod of length L which satisfies
the initial temperature u(x, 0) = f(x) and...

The spin of an electron is described by a vector psi = column vector with two entries,psi up and psi down
Give the general expressions for the probabilities to find Sz= +or- h/2 in a measurement of S^z
where Sz=h/2(1 0) as a matrix
( 0 -1)
ii)Give the general...
b) Calculate the matrix which represents the Hamiltonian
H= 1{(L)^2}/2I + Alpha*(L^z)
H = part A + part B
where alpha is a constant and so is I and also L^2 = Lx^2 + Ly^2 + Lz^2 (1)
heres what i have done. i have calculated L^2 From adding matrices from 1 and it...
could anyone help me also with this question as i am very confused,i have read my notes but i really have a problem with this stuff making anysense, any help would be appreciated thanks:redface:
question 6))
The Yukawa potential is given by V°(gamma)(r) = (q)^2/{

The spin of an electron is described by a vector
spinor and the spin operator
^S = ^ Sxi + ^ Syj + ^ Szk with components
how would i go about normalizing a state like the one below,i am miles away to what is going on here
c) (i) Normalise the state (1 1) *this is meant to be a column...
i have studied my lecture notes back to front and looked high and low for a clue how to do this question but i tried in a) constructing an expression for u and came up with DU= +TDS -PDV - FDL BAUT I COULD BE MILES OUT. could anyone help.
thanks
here it goes:

can anyone help?? in quantum mechanics commutator prove [L^x,L^y] = ihL^z
given
:L^x =(y^(pz)^-z^(py)^)
:L^y =(z^(px)^-x^(pz)^)
:L^z =(x^(py)^-y^(px)^) where ^ is just showing its operator
prove comutator [L^x,L^y] = ihL^z
I am swamped at every hurdle and cant seem to get my...
