    Very interesting and useful lecture.
    Just a comment, the initial steps in a MCMC were called "Burn in" to put something into a place, not "burning" as to put something in fire,
    This also confounded when setting up computers with their firmware and software.
    ... Thank you for the lecture it has helped me a lot

    -What does coordinate parametrization invariant means?
    -can someone explain in 12:21 why does mass get's shifted?
    -What does the mass describe mathematically? d\theta pi(\theta) or the cdf inside the radius r?

    Is there any place where I can get the slides?

    what does the "r" mean? what is the radial component? any reference?

    14:45 - there's an error in the denominator. You should integrate all the other variables, except theta_1.

      yes, that one threw me off.

    If more highly curved space sucks up more energy, could this be an explanation for dark matter?
    1:17:39
    This looks like an illustration of inflation theory. The mode being negative seems to indicate the presence of dark energy. Whereas if the mode was positive, the universe would contract.
