So I want to create gamma matrices like this one:

and the four Pauli matrices. So how can I create this one if I have defined the identity matrix (2X2) and the zero matrix(2X2).

 I have tried this:

with(LinearAlgebra);
ga_zero := matrix(4, 4, [ZeroMatrix(2), IdentityMatrix(2), -IdentityMatrix(2), ZeroMatrix(2)]);

Which, of course, did not work. I knew it from the start. But I am wondering how to do it.

Thank you in advance for your help

I want to load some specific constants at the beginning of my document. I load the ScientificConstants package first. Then I use a list of names of the constants I need. But the assignation in the loop does not work. Only the value and the units appear in the list, but they are not assigned to the letter. See the document included for more details.   Using_the_constants_.mw

Thank you in advance for your help

Look at the equation (11) in the Maple's document. I would like to force Maple to let the variable "r" inside the squared root so to get the equation (12). Any idea of doing that?  Thank you in advance for your help.

restart;

with(Physics);
with(Vectors);

Given

Ket(i) = alpha*Ket(u) + beta*Ket(d);
Ket(o) = gamma*Ket(u) + delta*Ket(d);
and using

<o|u><u|o> =1/(2)
<o|d><d|o> =1/(2)

 <i|d><d|i> =1/(2);
 <i|u><i|o> =1/(2);

Prove that
                     "alpha^*alpha = 1/2"

and the same for the rest of the unknowns

If you could help me start using them because later I will have a lot to check.

Thank you in advance for your help.

Then go to the plot section. I would like to see the commands that were used (complexplot3d I guess) to plot the first Zeta Riemann function in 3-d. Usually, you go to the cell where you se the output that you are interested in. Then you right-click and choose properties of the Array. Then you check the "Show input". Then you click OK and you are suppose to see the input that generate the 3-d plot of the Riemann Zeta Function.

But it doesn't happen. So maybe I am doing something wrong. Any idea?

Thank you in advance for your help.
