    Beginner/Novice Circuits - Seeking Suggestions

    Are there any good books on EE in general that are not like textbooks?

    What websites/magazines/news sources do you check daily?

    Just looking for some good science/engineering related reading

    Is there going to be more or less demand for analog designers in the future?

    On the one hand, there the argument that things are going digital, and most IC design firms now try to have as few analog components as they can. On the other hand, as long as you're interfacing with the real world, you can never really design a completely digital system. Also, I hear that...

    Which areas of EE do you think will grow the fastest over the next 5-10 years

    Just wanted to get people's thoughts on which fields of EE will have the most innovations/breakthroughs in the next few years.

    Engineering Why don't more engineers/scientists go into finance

    Anyone attending or graduated from an Ivy League or similar caliber school has probably seen tons of undergrads going to work at firms like Morgan Stanley, Blackstone, JP Morgan, Goldman Sachs, etc. These places pay first year analysts about $100K after bonus, second years about $150K, and third...

    Undergrad Solve a = b^(logx), for x: Steps & Explanation

    I can't seem to remember how you solve a = b^(logx), for x. What are the steps for simplifying this again?

    Converting a Matrix into an Orthonormal Basis: Solving the Gram-Schmidt Problem

    Homework Statement So I need to use Gram Schmidt to convert a 3x3 matrix A into an orthonormal basis. This is straightforward enough. But then I need to 'keep track of your steps to produce an upper triangular matrix B so that AB is an orthogonal matrix.' I'm not sure what this second part...

    Undergrad Can't remember how to do this simple definite integral

    ^but what does that give me for the definite integral? ln [v(k+1)T / v(kT)] ?

    Undergrad Can't remember how to do this simple definite integral

    If my Force = (-gamma)(dx/dt) velocity v = dx/dt Mass m (m)(dv/dt) = F = (-gamma)(dx/dt) Now I want to integrate it over kT<= t <= (k+1)T Rearranging gives me (dv/v) = (-gamma/m)dt The right side integrates to (-gamma/m)(T), but how do I integrate the left side over kT<= t <=...

    Engineering Solve RC Op-Amp Circuit Connected in a Non-Inverting configuration

    How would you solve an RC op-amp circuit connected in a non-inverting fashion, such that the second resistor is replaced by a capacitor. This is not the usual differentiator or integrator circuit as far as I can tell? No specific problem, just generally speaking, how would you approach this

    High School General question about floating/sinking objects

    Ok so I understand that whether an object floats or sinks depends on its density vs the density of the solution, and an object that neither floats nor sinks (sorta hovers in the middle) probably has the same density as the solution. My question is: is there any difference between an object...

    Uncovering the Pattern: Factoring and Vanishing Points in Determinants

    Homework Statement Alright so apparently there is some pattern in finding these determinants: for the 2x2, the determinant of |1 1| |x y| is y - x for 3x3, the determinant of |1 1 1 | |x y z | |x^2, y^2, z^2| is xy^2 - yx^2 - xz^2 +zx^2 + yz^2 - zy^2 Apparently that can be...
