1. ### Guess I'm going to have to give in and learn a language

Since you're starting off with no programming knowledge, I would probably suggest a book like Mark Lutz's Learning Python. I learned Python using Alex Martelli's Python in a Nutshell and David Beazley's Python Essential Reference, but I already had programming experience in C, Java, and MATLAB.
2. ### Help which language best suits my situation?

Based on your rather vague description of your requirements, MATLAB probably is the best fit: http://en.wikipedia.org/wiki/MATLAB
3. ### LaTeX Latex table help

4. ### Optics, image

This part of the problem statement means that the object is located 1.2 m in front of the first refracting surface of the crystal ball (1.3 m from the center of the crystal ball, and 1.4 m from the second refracting surface of the crystal ball). The displacements z0 and z1 in the equation are...
5. ### Optics, image

To get you started, the equation for the first surface is \frac{1.5}{z_1} - \frac{1}{-1.2} = \frac{1.5 - 1}{0.1} which you should solve for z1. This gives a location for the image formed by the first surface relative to the vertex of the first surface. Then you treat that image as the object...
6. ### Optics, image

Born & Wolf is way too advanced a book to be using to solve a problem like this, but the equation you want is in section 4.4.1 (in the sixth edition--it may be different in other editions), "Refracting surface of revolution," and it's the one that looks like this \frac{n_1}{z_1}-\frac{n_0}{z_0}...
7. ### LaTeX LaTeX sometime the arrow is over the right

$g(\vec{t})$ Note the curly braces.
8. ### MikTex 2.8 for beginners

MikTeX now comes with a basic LaTeX document editor called TeXworks, which you should find under "Start Menu"->"All Programs"->"MikTeX 2.8". Run it, and enter the following document: \documentclass{article} \begin{document} \title{Example Document} \author{John Doe} \maketitle This is...
9. ### A four bit adder logic circuit block diagram

Alternatively, a truth table for the sum s and the carry bit co for the addition of two 1-bit numbers a and b could be illuminating... :wink:

12. ### MATLAB Create a Hologram with Matlab?

It is not the superposition of the fields (the addition process O+R) that results in interference, but the determination of the intensity of the superimposed fields (finding the modulus squared of the total field \lvert O+R \rvert^2). Let O(x,y) = o(x,y) \exp [i \phi(x,y)] where o(x,y) and...
