    What are the "central/axiomatic equations of physics" from which all others can be derived? For example, it couldn't just be Newton's 3 laws, because they don't say anything about electric charge, besides the fact that there is relativity. Is there a minimum set of maybe 8 equations and/or...

    How does the energy from ATP get to converted to mechanical energy?

    OK, so ATP releases energy. At what point are things moving? How does this "energy" lead to a muscle fiber contracting?

    Get vibration frequency form absorption spectra line

    OK, thanks. Also, I'm unsure about the last part of this question - to approximately what temperature would the gas have to be heated to excite vibrations thermally? Again, I feel like there is just some equation or basic fact that I should know to solve this, but it isn't clear to me what...

    Get vibration frequency form absorption spectra line

    Homework Statement [/B] "Absorption spectra of gaeous HCl show a line at 3.5 μm which results form molecular vibration (oscillation from interatomic distance)" How do I get the frequency of vibration from this? Homework Equations ? If I knew this, then I could probably solve the problem The...

    Equipartition ceasing to apply at what temperature?

    Homework Statement A tuning fork has a frequency of 440 Hz. A) What is the size of one quantum of energy of vibration? B) To approximately what temperature would the fork have to be cooled before equipartition would cease to apply to its thermal motions? Homework EquationsThe Attempt at a...

    I What differential equations need to be solved more quickly?

    This is for my Bachelor's degree in computer science (last semester as an undergraduate). I have to do a senior thesis, and I got thinking about alternative models of computation (like analog, massively parallel, biologically inspired, ...) and was curious about figuring a cool way to solve a...

    I What differential equations need to be solved more quickly?

    I'll rephrase. Let's say one wanted to do original research as a university student on algorithms to solve certain differential equations or systems of differential equations. What (individual or systems of) differential equations would be worth focusing on? By "benefit", I mean that they...

    I What differential equations need to be solved more quickly?

    For what differential equations would having much quicker or financially cheaper methods of solving them significantly benefit scientists or engineers?

    Two Identical Pendulums Connected by a Light Spring

    Homework Statement Two identical pendulums of the same mass m are connected by a light spring. The displacements of the two masses are given, respectively, by xa = Acos( (w2-w1)t/2 )cos( (w2 + w1)t/2 ), xb = Asin( (w2-w1)t/2 )sin( (w2 + w1)t/2 ). Assume that the sprint is sufficiently weak...
