    Graduate Are there 'complex' numbers in classical mechanics?

    Wondering if it is only the formulae of quantum mechanics that routinely include complex numbers (a real component plus an imaginary one, e.g. i (the square root of -1)). If so, doesn't this immediately suggest (or even demand) that the (un)reality of the quantum realm is fundamentally unlike...

    Graduate Is the Delayed Choice Experiment Justified?

    Ouch! And thanks for correcting me. I should have said photons which, unlike electrons, are mass-less. In this case, there would be no delay at all, and the original argument survives ... no?

    Graduate Is the Delayed Choice Experiment Justified?

    Hello, I'm uncomfortable with the usual description of this experiment and wonder if this is justified. In a nutshell, when (in the usual double-slit setup) detectors are placed between the barrier and the final screen -- such that an electron, say, has already passed the two-slits -- an...

    Examples of quantum mechanical involvement in biological systems

    Hello, Can anyone can point me to any well established examples of quantum mechanical involvement in biological systems besides photosynthesis, e.g. http://www.lbl.gov/Science-Articles/Archive/PBD-quantum-secrets.html" ? I've only seen some other (speculative) involving quantum "spin" and...
