  1. 4. is from B5 when Ivonova is having "sexual intercourse" with an alien ambassador (without actually having intercourse).

    3. is from red dwarf, but Space help if I remember from where (something to do with the devil maybe)

    2. the costumes look like they are from Dr. Who the original series, though I don't know exactly where or what.

  2. I find this to be quite funny in an absurd way.

    I mean the bot introduced itself, criticized the forum for not having an introduction thread and at the same minute started publicizing dental work.

    This is ingenious smile

  3. The thing is I worked with a Phd. student on a project for growing crystals (I was a B.Sc. student) and he was very insistent about diffusion being a separate mode.

    The difference between conduction and convection is (and was) clear to me, my only problem is with diffusion,

    from this:

    α = k / cpρ is the thermal diffusivity, a material-specific quantity depending on the thermal conductivity k, the mass density ρ, and the specific heat capacity cp.

    and is interconnected with convection through the heat capacity of an object (in my case, the crystal or the flux).

    (And don't forget that all of these, so called, constants are dynamic through their dependancy on temp.).

     

  4. This is about thermal physics.

    Back in Uni I've been told there were three main modes of heat transfer: Convection, Conduction and diffusion. (and a few secondary modes such as radiance/radiation)

     

    I understood that Convection is the transference of heat by way of hot particles moving from one point to the other.

    Conduction is the transference of heat by way of particle collisions.

    But to me Diffusion (traditional diffusion is the movement of particles in such a way that equilibrium is met at its end (e.g. if one side is hot and the other is cold then equilibrium will be met when both sides reach the same temperature) ) seems like a kind of an average of both other modes, so why is it considered an independent mode? (other than because of the mathematics (diffusion is a a natural solution while convection is a forced solution (if I'm not wrong ) ) )

    Short answer : yes.
    Long answer: but only if you had that singing voice and a portable hole (so you could enter people's fridges unannounced and unperturbed (except for the obvious frost bites, of course (of course (I'm a horse(and my brother Swen is a moose))))). laugh

    Please excuse the announcer of the previous paragraph he is so very tired by the time he get's to write these answers, and so am I. (Swen the moose)

    *a throat is cleared*

    Please excuse both of the previous announcers for their silliness they have been both dealt with forthwith and will impose on this broadcast no more.
    Thank you and we hope you will have a pleasant reading and a good evening. And now we will return to our previous discussion of extraterrestrial life and the likelihood of their existence. Lama!!! (40 specially trained Ecuadorian mountain llamas)

    We've barely found it on Earth, for instance.
