  • As best as I can tell, it looks like general relativity, with a smattering of quantum mechanics.

    You mean you didn't hear about the new anti-grav erasers?

    And a hyper dog dick.

  • If I sleep now, my nightmares will be filled with dogs taking over the world and doing science to make their dicks hyper.

    Thank you for putting that idea in my mind 10 minutes before i sleep sir or madam ._.

    Oh you didn't know about them yet ??
    These days gravity does not effect erasers because of [censored by the government] and stuff.. so yeah science

  • The math is nonsense: the use of the Dirac brackets, inner product symbol, and asymptotically greater than symbol make no sense. It's meant to look like Riemannian Geometry. A lot of what is written on the board makes sense in isolation, but put together it's a jumbled mess. He's also using an incorrect notation for the Lie commutator representation of his T^hat transform, using Einstein notation in one term and normal notation in the other.

  • Hello I am science dog.

    The math here represents :

    1) A solution to the Klein-Gordon equation in the metric described

    2) The metric tensor for a Morris-Thorne wormhole and its stress energy tensor

    3) The operator for the stress energy tensor of a scalar field, and its renormalization (by dimensional regularization)

    4) A quantum squeezed state

    5) The quantum inequality for a scalar field (in flat space)

    I did sort of cheat on a few points (the stress energy tensor and the metric aren't in the same coordinate system) some of the notation is pretty loose (I do discard some Einstein indexes and the quantum state subscript for the expectation value, and I make a liberal use of ~), but the math is globally correct and more or less tied together around the thematic of an Ellis-Bronnikov wormhhole held open by a massless scalar field.

    Thank you and have a nice science.

  • They represent the (asymptotically) sine-like scalar field, obviously. The dog is marked as "j(x)" because he is the source!

  • No, that's basically what I expected (although I know so little mathphys I can't differentiate it from regular DG). I'm not saying any one, particular line is meaningless; just that put together they don't mean anything. It just looks like a bunch of formulas yanked out of different and disparate parts of a book. I mean, you have an equation with no \rho, but then an implication to \rho = \frac{6'}{8\piGr^t}; same with \tau obv. But why do you have three terms on the other side of the Klein-Gordon equation?

  • They are indeed rather disjointed, but it is more because they are bullet points rather than a full demonstration (I don't have the giant blackboard of A Serious Man to do it). The implication to the rho and tau are from rather standard results, though, the metric implying the energy density and tension is not particularly weird.

    The three terms of the solution to the Klein Gordon equation are the time dependant part, the angular one and the radial one (the first two are trivial, as they are just the exponential function and the spherical harmonic function).
