Hi, just wondering if anyone would happen to know of some good books on semiconductors/intro semiconductor physics. Any names would help a lot tnx. Manu

Hello. I was studying for intro physics on topic of electromagnetism and stumbled upon one problem. Q. A thin wire of lengh L is made of an insulating material. The wire is bent to form a circular loop, and a positive charge q is distributed uniformly around the circumference of the loop...

Should science be value-free? SHould science isolate itself from value and morality?

I was wondering, if it wouldn't be too boring for any of you, if someone could post an intro to multivariable calculus, from partial differentiation up through the grad, curl, divergence of vector fields, preferably with applications to physics. Maybe you can post a sticky or something. I'm...

Hey guys, I'm not sure if introduction posts are the norm here or not.. if not then I'm risking looking like a klutz eh? Hehe... Anyway I just posted my first message in a book thread and thought I'd make an official "Hello" post here. It's 2 AM and I have nothing to do so I decided to take...

I am struggling with intro physics in my freshman year of college. Are there any decent review books where the solutions are worked out you could suggest to me to help me further my studies. Thank You

My intro to digital system teacher is hard. He gives question that ask u design circuit such as make a counter that count 3 5 9 0 3 using mod-6 counter + encoder + decoder. Do question like this have a systematic way of solving or is only solvable if u have mad experience? He seems to give...

hello all, i'm a college freshman and have a physics problem that i am haing a tough time figuring. Here is the problem "Neutrons traveling at 0.400m/s are directed through a double slit apparatus having 1.00-mm separation. An array of detectors is placed 10.0 m from the slits...

Hello, I am having trouble understanding the definition of components and connectivity. Here is the definition I have been given in my text: Alright, I know that a subgraph is a subset of vertices and edges which itself forms a graph. I also know that a path is a subgraph in which no edge...

My intent is to create a thread for people interested in Differential Equations. However, I will explicitly state that I am only a student of this class myself and that many things could end up being incorrect or an improper way to present the material. I will merely be going along with the...

Hi again, This is the question: An explorer is caught in a whiteout while returning to base camp. He was supposed to travel due north 5.6 km, but when the snow clears, he discovers that he is actually 7.8km at 50 degrees north of due east. a)How far and b) in what direction must he now...

I like the Geometric Algebra approach to incorporating differential forms into physics that is taken by Dr. David Hestenes and contained in his numerous works over the last few decades but see no mention of Geometric Calculus here. Are you familiar with it...

don't want my words on PF
