  1. Say something silly to a Greek Cypriot and they will say...

    Peeeeeeeeeeeeeeeeeeeeeeeeee...

    :bleh:

    :lol:

    The castration by Cronus of his father (Uranus) out of whose severed testicles sprang Aphrodite.

    And Heaven came, bringing on night and longing for love, and he lay about Earth spreading himself full upon her. Peeeeeeeeeeeeeeeeeeeeeeeeee... :thumbsupsmileyanim: Then the son from his ambush stretched forth his left hand and in his right took the great long sickle with jagged teeth, and swiftly lopped off his own father's members and cast them away to fall behind him. Peeeeeeeeeeeeeeeeeeeeeeeeee... :thumbsupsmileyanim: And not vainly did they fall from his hand; Peeeeeeeeeeeeeeeeeeeeeeeeee... . :thumbsupsmileyanim: And so soon as he had cut off the members with flint and cast them from the land into the surging sea, they were swept away over the main a long time: and a white foam spread around them from the immortal flesh, and in it there grew a maiden. Peeeeeeeeeeeeeeeeeeeeeeeeee... :thumbsupsmileyanim: Her gods and men call Aphrodite, and the foam-born goddess and rich-crowned Cytherea, because she grew amid the foam, and Cytherea because she reached Cythera, and Cyprogenes because she was born in billowy Cyprus. Peeeeeeeeeeeeeeeeeeeeeeeeee... :thumbsupsmileyanim:

    :D;)

  2. :lol:

    This joke actually has an interesting history. I say this, well, in case anyone is interested! :rolleyes:

    The person who originally did this was the inspiration for the character Sherlock Holmes.

    Dr Joseph Bell was a medical professor at the University of Edinburgh

    Sir Arthur Conan Doyle, the creator of Sherlock Holmes, was from Edinburgh and studied medicine under Bell, and later worked with him (I believe) at the Royal Infirmary. He said that Bell was his inspiration.

    Anyway, since at least the 1930's, the original version of this anecdote has been attributed to Bell, as something he would tell his medical students:

    One day, in the lecture theatre, he gave the students a long talk on the necessity for the members of the medical profession cultivating their senses — sight, smell, taste, and hearing. Before him on a table stood a large tumbler filled with a dark, amber-colored liquid.

    "This, gentleman," announced the Professor, "contains a very potent drug. To the taste it is intensely bitter. It is most offensive to the sense of smell. Yet, as far as the sense of sight is concerned — that is, in color — it is no different from dozens of other liquids.

    "Now I want to see how many of you gentlemen have educated your powers of perception. Of course, we might easily analyze this chemically, and find out what it is. But I want you to test it by smell and taste; and, as I don't ask anything of my students which I wouldn't be willing to do myself, I will taste it before passing it round."

    Here he dipped his finger in the liquid, and placed it in his mouth. The tumbler was passed round. With wry and sour faces the students followed the Professor's lead. One after another tasted the vile decoction; varied and amusing were the grimaces made. The tumbler, having gone the round, was returned to the Professor.

    "Gentlemen," said he, with a laugh. "I am deeply grieved to find that not one of you has developed this power of perception, which I so often speak about; for if you had watched me closely, you would have found that, while I placed my forefinger in the medicine, it was the middle finger which found its way into my mouth."

  4. Okay, beginning to scrape the barrel with the X's!

    This is an 'X-Data' watch that, well, you put on your belt and hang your keys off. Fugly! :lol:

    Google for it, you'll see it's a quartz.

  5. Sigh. It would be a lot easier if you just explained it like a four dimensional cube... :rolleyes:

    See the corner bottom left? That represents the Thai postie running as fast as he can!

    Here, dt, dx, dy, and dz are all co-ordinate differences between two events that are "near" each other on the TTK diagram. (So if (t,x,y,z) are the co-ordinates of one event, then (t+dt,x+dx,y+dy,z+dz) are the co-ordinates of the other.) Time and space are measured in units for which c, the speed of light, equals 1 (e.g., seconds and light-seconds). And , finally is the proper time difference--- which we define next.

    Say someone, wearing a watch, coasts uniformly from event (t,x,y,z) to event (t+dt,x+dx,y+dy,z+dz). The time between these two events, as measured by that person's watch, is called the elapsed proper time for that person. And according to TTK, the proper time is given by in the formula above.

    More generally, suppose someone carrying a high-quality time-piece travels some world-line from event E to event F. "High-quality" here means that acceleration doesn't affect the time-keeping mechanism. A pendulum clock would not be a good choice! A balance-wheel watch might do OK, a tuning-fork mechanism would be still better, and an atomic clock ought to be nearly perfect. How much time elapses according to the time-piece? I.e., what is proper time along that world-line between events E and F? Well, simply integrate :

    78090-31040.gif

    where

    78090-31041.gif

    is the velocity vector, and [v(t)]<sum> is the square of its length:

    [v(t)]<sum> = (dx/dt)<sum> + (dy/dt)<sum> + (dz/dt)<sum>

    You shouldn't have much difficulty obtaining these formulas from what we've said already.

    Our integral for the proper time can be difficult to evaluate in general, but certain special cases are a breeze. Let's take Terence's case first. Remember that his event co-ordinates are always (t,0,0,0), so dx, dy, and dz are always 0 for him. So is just dt, and the forbidding integral becomes:
