    Electronic Steam Tables Programs

    Looks like the excel add-in only includes a limited amount of the function library. Or am I missing something? Do I need anything except for the excel add-in files?

    Electronic Steam Tables Programs

    Hi all, Been a while since I posted in these forums. Looking for advice on steam table software package. I am looking for a relatively simple software package to look up steam properties. Preferably compatible with Excel. It at least has to be able to compute SH steam enthalpy as a function of...

    Problems in the modern semiconductor/electronics technology?

    Since I am asking about research in QM/Solid State Physics, I thought it would be appropriate to put this question here. I will not be offended if it will be moved to the EE forum From what I have read, the problem with modern semiconductors/electronics seems to be quantum tunnelling and...

    Geometry problem. Circle and parallel lines to a circle.

    A circle with diameter 90 is located at (70,100). A given point O is at (0,0). There is a line from O to the circle at point A, line OA. Line BT is parallel to OA at a distance 50 from OA and is a tangent to the circle. How do I find the coordinates A and B? I'm having problems drawing...

    Conserved quantities in the Feynman diagrams.

    Seems to me from the book that every property of the particle is conserved on the node. Or am I drawing the wrong conclusion? momentum, charge, Spin, Isospin, Hypercharge, strangeness, baryon number, lepton number, color ...

    Conserved quantities in the Feynman diagrams.

    I'm currently reading Griffiths book (I'm at chapter 4) on Particle physics, and I had a question about Feynman diagrams. In every "node" of a Feynman diagram, what quantities are conserved? Further, what quantities are conserved over the entire diagram?

    Schools Find Scholarships, Financial Aids for US Universities' Tech & Physics Depts

    Thank you for the reply. Did not know that SF was one of the most expensive ones. Concernig other schools, I'm open for suggestions. There are a lot of people on this board who have studied physics in the states.

    Schools Find Scholarships, Financial Aids for US Universities' Tech & Physics Depts

    I'm looking for a university in America that has a good technology and physics departments. I have BS in physics and EE and I'm looking for a school for further studies(preferably in physics). I was eyeing Berkeley, and I called and asked. They said it was around 45.000$ per year for an...

    Concerning Quantum computers and information

    So will a computer-scientist today have to relearn a lot when we'll start using these computers?

    Concerning Quantum computers and information

    I only recently 'discovered' this quantum computer business and quantum information. As I see it, this seems like a drastic departure from regular 'classical' computers. So if we ever get to the point of using these computers, won´t they have to rediscover the entire field of...
