Mistaken to antigravity ?

  1. -I got it on the eBay for < 20 USD.
    It's cool. I Got the one with the compact wooden keeper box.

    Pyrolytic Graphite *Self-Floats* over four strong Ni cube shaped

    I'm glancing up at the thing now, as it dances slightly in the breeze.
    It's very enegmatic, or yes, Bizarre. I have no explanation yet.

    Wait! Found:
    Carbon-Based Magnetism - T. Makarova, F. Palacio (Elsevier, 2006)

    From Pages 252 to 262:

    ...the anisotropy of the bands near the corner points of the first
    Brillouin zone is a consequence of the hexagonal symmetry of the graphite


    ... Wallace remarked that the anisotropy is of the same order of magnitude
    as that of the conductivity

    -So we guess electrons in the crystal "ram-up" and get trapped into
    corner angles when pushed magneticly ?

    I still find it wierd, -and cool.

    This is EPrey item 180186727424 ???
    Currently at $45.00!! :(
    You can get more lift buying an all day ski pass on a ski mountain!

    Whistler mountain looks as low as $42.00/day. (Here in BC.)
    The ski lift will raise any exotic material to an elevation of 7156ft.

  5. You didn't ask for a link _to ebay_, now did you?
    I never _had_ the ebay link, and since the OP
    says s/he "got" the item, presumably it is
    no longer for sale there.

    Has this functional illiteracy problem been
    bothering you for a long time, or is it new?

    If the latter, an MRI might be a good idea.

    The emergency room caretakers found a brain
    tumor the size of a small orange in my
    fiancee's head, that was giving little more
    sign than that of being around, until the
    crisis hit.

    xanthian, she's no longer got the tumor, and
    she's regathered most of her faculties since
    the tumorectomy. I'm hoping to have her home
    in a month or so.

    Are we talking the softball sized oranges, or those awesome little ez-

    Average brain volume is 1400 cm^3. That sucker has a volume of about
    140 cm^3. That's a lot of brain missing. I know I'd miss 140 cm^3 of
    grey matter, no matter where it came from.
  9. [size of Jeanette's brain tumor]
    Well, plus her head was noticably small even for a
    woman, with about a US 6 7/8" hat size, and women in
    general get the same work done with smaller average
    sized brains than do men, so it was probably
    proportionately a bit more than 10% for her.

    It sure loomed scarily huge in the "before" MRI
    scans I reviewed, but that was a cross-sectional
    plane view, which exaggerates the comparative size,
    not a volume view.

    It sure left a huge fluid filled void for her brain
    to recolonize, in the "after" MRI scan.
    Well, it didn't exactly "go missing", there was
    nowhere for it to go. Brain tissue is soft and mushy
    and soaking wet and pliable on its best days, so it
    just got _displaced_ by the tumor, and got the fluid
    compressed out of it so that it was starving pretty
    badly for lack of room for blood to circulate

    The tumor was a "benign" one, so it didn't
    particularly infiltrate the existing tissue, just
    grew as a compact mass in one place within it. Thus,
    minus some unavoidable very thin "selvage", what was
    cut away wasn't her brain, just the tumor inside it.

    The damages seen may be in that cut away selvage,
    but blaming the starvation and maybe some ill
    effects from stretching the existing nerve tissues
    as they were displaced, seems the surer conviction
    to seek.

    Her frontal lobe ended up moved toward the top of
    her skull and compressed, at least the center of it
    where the tumor was did, so overall it was probably
    sitting as an inverted "U", while the parts of her
    brain directly behind the tumor got quite badly
    compressed and starved, and the non-nerve tissues
    toward the front of her head had lots of "internal
    pressure" symptoms, if only we'd been smart enough
    to recognize them.

    Brain tissue further away from the tumor center
    probably didn't fare as badly, though compression
    goes through fluid and pliable tissues pretty
    thoroughly, so maybe it was all equally stressed.

    Trouble is, lots of the stuff that makes us human is
    up front there, as is the start of the vision
    processing system; she's having to relearn how to
    see the same image out of both eyes, for example.

    She was complaining for two years about pain and
    pressure behind her eyes, but as one of the
    uninsured and destitute in the US, she had no way to
    pay to get that investigated, and as too mentally
    ill to get herself signed up for the insurance, no
    way to overcome that issue on her own, and I had no
    legal standing to do that for her.

    Once the hospital had her in its care and were
    ringing up charges she had no hope ever of paying,
    the hospital administration got her onto the local
    "medical insurance plan for the indigent", so they'd
    get paid by _someone_, fast enough.

    The operation to remove the tumor, I'm told by one
    of the nurses, involved first carefully shoving
    aside everything above it by following a major blood
    vessel down to it, then cutting around the tumor
    repeatedly, about 1 mm deeper each time. From the
    time she left her intensive care unit until she
    returned to it from surgery was 11.5 hours, three
    hours longer than originally planned.

    I'm glad they did such a careful job on an indigent
    patient, but then the hospital is a Catholic
    "charity" hospital (while still one of the top
    ranked neurology hospitals in North America), they
    try to do that for everyone, even where payment is
    impossible, not just hard.

    She's having a recovery that is astonishing even her
    nurses, so one concludes that this could be going
    much, much worse than it is, and, if one is wise,
    one practices patience and tolerance. Patience and
    tolerance aren't exactly my most stand-out virtues,
    though, as hundreds of thousands of Usenetters who
    know me will testify, so a lot of keeping my teeth
    grinding pending until after our visits end is
    happening on my side.

    There are still _lots_ of holes in her thinking,
    behavior, motor skills, and memory [she didn't
    recognize the word "annotating" last night (when I
    used it to talk about adding descriptions to some
    web page links for a page I just started), while I
    was with her, and her with a master of fine arts
    degree in teaching music where music annotation is
    surely a hot topic], e.g., she called me by her
    ex-husband's name off and on for a few days, but
    then two days ago she sat down at a piano for the
    first time in almost three years and played a very
    recognizable one minute snatch of "The Entertainer",
    with few errors, and from memory.

    Compare her case to the other music teacher by
    coincidence also in the recovery ward, now for five
    months, after a car wreck, who is enduring being
    taught how to survive the rest of her life as a
    quadrapelegic, and you'll see just how lucky my
    fiancee is to be coherent, walking, retaining some
    skills, and in control of most of her faculties a
    week less than a month after surgery.

    Well aware that she had a good chance of coming back
    to the ICU after 11.5 hours of people poking knives
    into her head as some new species of vegetable, I
    started and ended my want list for her after surgery
    at "breathing", and only thought about extending it
    when that part seemed to be secured another day
    later and she began to regain awareness of her
    surroundings, so most of the rest of this is pure
    gravy from that starting point.

    It sounds like she is doing pretty well considering. I wish you two
    the best of luck.

    Most of the search engines don't catalog eBay. I think eBay discourages
    that; they'd rather have their nonspecific "Get all your <search term>
    on eBay!" paid links pointing to their own search page.

    (Of course, this can generate some humorous results, as when you search
    for things like "B-2 bomber name".)

    Here, children, you can have mine. It listed four current auctions:

    the most expensive of which was under $20, total.

    Interesting stuff...
