    Have not seen that since I was a teenager, when I saw it several times in a row, so from memory, Omar Sharif eventually arrives from being a dot on the horizon: Although then maybe that happens later in the film.

I have a cousin who thought bugging me everyday about my weight would make try to lose weight. Silly things children think. Plus since she was on my family property I had the right to get rid of her, I was just trying to scare her. At the time my grandfather and the neighbor who owned the piece of property never could settled on where the property line was until the neighbor cut some wood on our land and eventually got surveyed and settled. It was not her family but she was friends with members of his family and was allowed to go thru until about then then there was a couple of fires and some broken glass across one of our paths.

    I find it interesting that movies with overtures also, in general, come from an era before the concept of "show times," so you can't even say, "Oh, people were still getting to their seats."

    We haven't been to the cinema in years, but I'd need an admission about every fifteen minutes because that's how often my prostate thinks I need to pee.

    Are you sure it's not the quality of the movies causing that?

    We've been seeing a lot of TV ads for "The Mirror", an interactive video screen you hang on the wall so someone can yell at you by name as you do your workout. I knew it reminded me of something but I didn't figure out what until last night. It's the telescreen from Nineteen Eighty-Four. Why the heck would I want that?

    Can it yell at me to go to sleep? I need a Mom to keep me disciplined in that regard when I’m away at college.

    When we first saw that ad, Halfway through, I shouted out “It’s a mirror!”
    Then, the announcer said it’s name.

    Maybe I shouldn’t be surprised -in the age of selfies- that people want to look at themselves while exercising.

    After seeing the ice on the north pole of Mars. I'm wondering why the ice doesn't sublimate to nothing over time since there shouldn't be much of a regeneration from the atmosphere. Any help?

    I assume it has to do with the vapor pressure of water ice at that temperature.

    Surface temperature of Mars at the poles is about -150C (wikipedia).

    I found this PDF with vapor pressure as a function of temperature down to -80C. At -80C, the vapor pressure is 0.00041 mm Hg, compared to 4.58 mm Hg at 0C. It has to be a lot less than 0.00041 at -150C. So probably get very little sublimation.

    IIRC, carbon dioxide ice forms over the water ice in the winter time. I suspect that covering also helps decrease sublimation.

    I agree with the values, but we are talking about millions/billions(?) of years at those sublimating pressures/temperatures.

    If the ice sublimates it will become water vapor in the Martian atmosphere. As long as it doesn't exit into space, it could just redeposit on the ice caps. I assume there is just an equilibrium between the ice at the poles and the atmospheric water vapor.

    In addition to the link above on the atmosphere, there are also wikipedia page on the ice caps and on water on Mars. I suspect the details of the relationship are in there.

    Yes I have read both pages and agree with water vapor becomes part of the thin atmosphere. It is estimated that the planet had a lot of water in the past but the low gravity was not able to sustain the water cycle and the liquid water escaped leaving frozen patches today. But the gravity hasn't changed nor the Sun blasting away at the atmosphere.
    Now I not saying there exists a mass conspiracy concerning water/ice/vapor on the planet, I just don't understand how the forces that eliminated lots of water, hasn't eliminated the remainder in all those years. It is a puzzlement to me.
    ETA: Not so much Enceladus as there is constant renewal/depositing of surface ice, just Mars.

    ETA2: The ice is there, just how does it remain?

    There must be a bare minimum. Mars' atmosphere has just enough carrying capacity to keep the last smidgen of H2O cycling intact. Maybe in another few hundred million years it'll finally dry up entirely.

    I guess that there is sufficient gravity to maintain an equilibrium, low as it is

    It's been escaping steadily over geological time. It depends on how much water gets to the exosphere, which is where escape takes place, and then on the temperature of the exosphere, which determines the mean molecular velocity. On Earth, the stratosphere is a sort of barrier to water vapour, because it all precipitates out in the troposphere, and layers above that are very dry. So although the exosphere temperature on Mars is certainly high enough for water to escape (and even more so its dissociation constituents), it all depends on how much water vapour can get into the exosphere without precipitating out.
    Coincidentally, we've just had a report on the relevance of dust storms to water escape on Mars.

    My wife spent about 16 hours yesterday watching live coverage of a current event we don't talk about here. Even the participants were falling asleep. I spent that time hiding out at the opposite end of the house with headphones on so I couldn't even hear it. Different strokes, I guess.

    I’ve been there before, and not even always with the news— my Dad doesn’t believe in wearing headphones and watches movies on the desktop computer in the living room so loud everyone in the house can hear.

    I remember when my older sister watched Iran-Contra all summer. Of course, at the time, that was your choice--it was on all the networks, and this was before most people had cable. I was definitely glad cable was around during the OJ Simpson trial, which may have been more dramatic but was considerably less important!

    There's a cruise line using Jefferson Airplane's White Rabbit as an advertising jingle. If there's a more iconic drug anthem from the 1960's, I can't think of what it is. Are they suggesting you can get LSD on board or something?

    I guess they are trying to equate taking a cruise with feeding your head.

    But...yeah. A strange choice, even if cruise lines are trying to attract boomers.

    That’s weird.

    Ask Alice.

    I would put a Steppin’ Wolf song up there with it, if in the 60s. Cocaine if in the 70s, though there were many drug songs to consider, including some from the Beatles.

    I had the same reaction; that's it is a very weird musical choice for a cruise. The video that goes with it matches the song pretty well (the woman shrinks down to a tiny size and runs around a hallucinogenic landscape) but again, not what I would think about for a cruise.

    Or Sloop John B.

    Many years ago I was taking a flight and the in-flight movie was a "based on a true story" about a sailing ship that was a training boat for some boys' school and was involved in a shipwreck. I thought that was like showing one of the Airport disaster movies (or "Snakes on a Plane") on a cruise.

    For many years airlines would not show in-flight movies that contained airplane crash scenes or had a plot about a crash. I was watching a film way back when (one I had seen before) and noted that the plot made a lot more sense with the crash scene intact. Now, with all of the video available, the airlines don't bother.
