    Physics Physics Major to Finance: Advice Needed

    I tend to think people go into Physics to get a rigorous take of applying analytical methods and quantitative techniques to understating/analyzing general systems and objects (which is something that can be used and applied to about any other field). This book might be of interest to you if...

    List file names from a directory - Vietnames

    Not sure if it would work on Vietnamese characters but I know it works on some symbols... A quick and easy way I use to get a text list of all the file names from a folder (sometimes with symbols) is use the Windows command prompt. Fist click on 'Start' then 'Run' and type in 'cmd' and...

    Quantum mechanics and DNA and RNA

    I once did a report on QM and molecular biology, which I can't find now... Here are a few topics I remember discussing: *Electron delocalization *Quantum Tunneling *Enol-Keto Tautomers *DNA mutation caused by UV Radiation About how QM specifically relates to the structure/stability of DNA...

    Course on Biophysics next semester but there's no textbook

    The description you listed doesn't seem focused on any particular area of biophysics, so I'm going to assume it's an introduction to biophysics class (introducing applications of physics concepts to biology). Here's some general lectures on Biophysics to begin with...

    Acid-Base Reaction: Calculating PH of NaF Solution

    [SIZE="1"]Hmm, I mistyped HF instead of NaF above (and also .2 instead of .02); Now corrected But I thought 0.02 was the equilibrium value of NaF since it said: "after titrating...the reaction had formed an aqueous solution of 0.020 mol/l sodium fluoride." ?

    Fascicle Arrangement & Muscle Structure: Videos & Info

    Fascicles are bundles of skeletal muscle fibers. Try searching for 'skeletal muscle fibers' or just 'skeletal muscles', instead of fascicles. Many videos exists on youtube that show how the fascicles arrange to form the structure of skeletal muscles...

    Acid-Base Reaction: Calculating PH of NaF Solution

    You don't need to know I, the initial, since we are given that the Equilibrium of NaF (C-X) is 0.020 The dissociation equation, as you said is: NaF + H20 <==> NaOH + HF (B + H2O <==> HB + OH-) or: F- + H2O <=> HF + OH- I C ...N/A.... C C -X ... +X ... +X E 0.020 ... +X ... +X Since we...

    Bonding, Nonbonding and Antibonding MOs

    Wikipedia has Carbon Dioxide as one of it's examples in the MO article: http://en.wikipedia.org/wiki/Molecular_orbital_diagram#Carbon_Dioxide_MO_DiagramHere is my summary using the images from the wiki article: The first image in the CO2 section is of the atomic orbitals (AO) of Carbon and...

    What is the hidden image in this optical illusion painting?

    Yep, yep, yep. Same photo from a different angle here reveals the answer: http://thechive.com/2009/12/21/daily-afternoon-randomness-30-photos/great-christmas-randoms-25/ More paintings here from the same artist: http://www.paintedalive.com/gallery.html

    What is the hidden image in this optical illusion painting?

    It looks like a leopard, and it is a painting, but there's more to it... Anyone see it? :biggrin: Hint:

    Physics Where to find entry-level jobs? B.S. in Physics

    Your college career website should have listings of entry-level positions. Physics is a pretty broad field. What area of physics are you interested in? What area was your undergraduate research in? This will help with knowing what types of jobs to search for (since there really isn't an...

    Entropy & Energy: Why Do Things Move Away from High PE?

    Yep! I think so. Energy and entropy are very much related. Things move away from high potential energy because of entropy...or more specifically, in order to maximize entropy. (Note: It also moves away from high kinetic energy states for that reason). And yeah, the reason it does so is because...

    Poisson Distrib: Prob 10 Tubes Show Growth

    I'm working on a similar problem. Can someone tell me where this equation came from? What's c and q (and what do those 2 10's next to the c mean)?
