    When a state university has campuses in more than one city, they tend to differentiate between them all by appending the city name to the name of the university.

    That's why there's UCLA, UC-Berkeley, etc. ( http://www.universityofcalifornia.edu/campuses/ ).

    Why, even Minnesota does it ( http://www1.umn.edu/twincities/campuses.php ); imagine that!

    So, just because *you* don't have time for this in your life, anyone else must be criticized/condemned because they do? Buddy, you're the one who either decided to have a wife and kids, or you let the little woman browbeat you into your present situation. Your attitude and that of anyone who agrees with you just sounds like sour grapes.

    I'm 43 too; I get up at 5AM, out the door at 5:30, at work by 7, out the door at 3PM, home by 4:30, pretty much the same sort of evening chores, so you're neither the first person nor the last to have a busy schedule.

    On a kinder note, let me assure you that your current schedule will get easier. I have 4 girls, so I've been there. It gets easier.

    In the meantime, try not to be too jealous of those who have chosen to live their life in a manner that doesn't match yours.

    I recently was part of a discussion about energy here in the US and this was my brother's contribution:

    It's quite simple, actually. The United States has not built a nuclear power plant since the seventies. Almost all of the plants we built then, and all of the plants that are still online, are pressurized light water (PLW) designs. This means that that coolant in the reactor, which also moderates the nuclear reaction, is ordinary water under great pressure (typically at least twice the industrial norm of 600 lb/in^2 steam). A PLW reactor produces as much plutonium 239 as it consumes uranium 235. We erroneously call Pu-239 nuclear waste, and the governments since the Clinton Administration have been looking to find a place to bury it for a quarter of a million years.

    However, until the Clinton administration, your government was busy designing a better reactor. The program was called integral fast reactor, or IFR. IFR was a metal-moderated reactor. The coolant was liquid metal, sodium or lead. These elements don't moderate the neutrons, they fly unhindered through the pile. That means they can fission Pu-239. In fact, they can fission anything higher than uranium on the periodic table. That's not all a fast reactor can do, though. It can also turn anything on the other (left) half of the bottom row of the periodic table into fissionable material. That's what "fast" means in the name. The reactor produces its own fuel from thorium or uranium in its natural state! Just the uranium that has been mined to date, which we use for cannon shells once we've taken the U-235 out of it, is sufficient for 300-400 years of the US energy needs. The known reserves are good for 50,000 years or so. Uranium is more plentiful in the earth's crust than gold or tin, and there is three times as much thorium as uranium. Energy forever.

    What does "integral" mean? It means that the fuel is recycled on-site. The fuel in the IFR is in metallic, rather than ceramic form. It is simply re-smelted periodically (not the whole load, just a few rods' worth), and the slag is the only waste. The balance of the fuel plus a tiny bit of uranium or thorium in its natural state, is recast into pellets and returned to the reactor. The volume of the nuclear waste is reduced by several orders of magnitude. The nature of the waste is only the light elements that are the products of the fission reaction. They have either extremely short half lives, measured in seconds to months, or such long half lives that they are essentially stable. They are also mainly low-energy beta emitters, instead of neutron and gamma emitters. While this waste is hellishly radioactive at first, it will be less radioactive than uranium ore in less than 300 years, and reactors might produce a couple hundredweight in a fifty year lifespan, instead of thousands of tons of spent fuel rods as a PLW reactor would.

    Additional benefits of the IFR design? The fuel is in metallic form, suspended in liquid metal. It gets no hotter than the coolant, and thus cannot have a catastrophic loss of coolant, or "blow down", which is what happens if there is a leak in the primary circuit of a LWR. The fuel in a LWR is in ceramic form, and gets much hotter than the coolant (which is in turn much hotter than liquid sodium). If it were not continuously cooled, it would destroy its container and melt, hence the term "melt down." If that happens to enough fuel elements in a reactor, the fuel gathers at the bottom of the vessel and continues to react, until it melts through the bottom of vessel, or the "china syndrome." None of these is possible with the IFR design. As it gets warmer, the fuel assemblies expand and move away from each other, slowing or stopping the reaction. The IFR, in fact, was tested for this. They turned off the control system. The reactor heated slightly, and stopped working. The cut off the heat exchanger (simulating what happens if the heat exchanger or a turbine goes bad at a LWR plant)--same thing. The reactor heated slightly and shut itself down,

    Sorry dude, the feminine form of the word to "chick" is "dude".

    "famine"? "akward"? As for the awkwardness of gal, speak for yourself. I like it just fine, and none of my gal friends complain about it.

    The feminine form of the word "bitch" is "asshole".

    Bitch is a feminine noun. It means female dog. However, I would offer "prick" as the term for opposite gender if we mean to stick to insulting humans. An asshole can be any gender, as both have them.

    The feminine form of the word "beefcake" is "cheesecake", and the feminine form of the word "stud" is "slut" or "ho".

    Slut or whore ("ho") would most likely be the feminine counterpart to "gigolo". A feminine counterpart to "stud"? "Bitch" for dogs, "mare" for horses. Humans? I don't know... I'd probably go with "babe".

    Thus, because we don't see the night sky in this way, the universe is both finite in size and age.
