    A Facebook post sent two women to jail for a few hours, but a Georgia court said that the arrest wasn’t constitutional, CNN reported Friday.

    Corey King, a sheriff’s deputy working in Washington County, Georgia, was upset about a 2015 Facebook post by his ex-wife, Anne King. The post read, "That moment when everyone in your house has the flu and you ask your kid's dad to get them (not me) more Motrin and Tylenol and he refuses." She added an emoticon to show she was "feeling overwhelmed."


    Control freaks are drawn to politics and law enforcement. How can this kind of crap be stopped.

  2. Magnets cannot "simulate" gravity. An MRI contains an extremely strong magnet, and I haven't felt any change in gravity when in one. The Large Haydron Colider has nearly 20 miles of strong magnets and no one has mentioned additional gravity, AFAIK.

    Much worse than that, since ALL the chickens would object to a fox. Almost half of the cluckers over here let him in and think he's doing swell.

    That's true. It's like many chickens are deaf and blind.

    He and his kids are still running so many business deals, this stock shakeup could be used as payback for favors, like the deal he got for Ivanka's trademarks in China while on state business, or the fast-tracking his resort permits got in foreign countries as soon as he was elected. He's got a license to steal now, and it's clear he's been planning lots of ways to capitalize on it. I'm not sure how payback like that could be traced back to him.

    He is a fox in the hen house.

    We seriously need to stop playing pool with these people who can afford all the lessons and equipment in the world, but still insist on cheating by blocking our shots, changing the rules, and leaning on the table while we're trying to make a living and enjoy the game while we do it.

    Unfortunately, it seems we must play and win or let them have their own way. I'm old and may at any time stumble and break my queue, but will, as long as possible, protest injustice and try to sneak a win sometimes. Support from the audience is welcome and essential to victory.

    It is illegal: Title 18 Section 208 of the U.S. code https://www.law.cornell.edu/uscode/text/18/208

    With his party and his nominees in control of all branches of govt the law simply isn't being enforced. Highways have speed limits and State Police to patrol them but those State Police aren't required to catch everyone who speeds. There is some discretion allowed in enforcement of all laws. Trump flexes that discretion to what was previously believed impossible. The words constitutional crisis were tossed around a bit prior to Trump's inauguration and since that time things have only gotten worse. 

    It seems to me there is only one party, taking PAC money and dancing to the tune "Money is our Savior."

  7. The sign-in screen gave me some fits just now. I'd been using facebook, but that didn't work. I got a new password via email, and sign-in gave me an error, but then logged me in. Maybe it picked up that I was logged in to another window. I'll log out now, and try to sign-in again. If you don't hear from me again, I'll be somewhere in the aether :)

    I exited my browser and started it again. ScienceForums came back OK.

  8. A survival skill that should be taught early in life is accepting constructive criticism. That means teaching an infant to know the difference between trash talk and good advice,. When someone responds like Phillip did to beecee's post, they feel unreasonably threatened, which was not beecee's intent. People like Phillip, who do not understand the difference, may forever be confused, because they do not know who to trust.

  9. It seems unlikely that roadster will be in orbit for than a hundred years. I think it will end up in the Smithsonian or a private collection.

    Forget Tony Stark.

    Think Batman.

    Self-made billionaire, who has his hands in many companies simultaneously. He's in the computer business, the A.I. business, the automobile business, the internet business, the space business, and even in the biotech industry.

    Jumping to subroutine is slower than jumping to code using goto (or assembler equivalent of it), because variable in registers and return address have to be pushed to/popped from CPU stack. More memory accesses required.


    Yes, at least on older machines. On modern chips there is so much caching and other run-time optimization it's possible there is no difference. It's best to run a test to be sure. 

  11. I think the fastest code will use an indirect function call, and a vector (array) of function address per array element. Then call the function via the array.

    Here is an example program that does an indirect call, but without the array. If you need help, let me know. It's been a few years and I'm rusty, but should be able to do it again.

    Sorry for the delay.

  12. I think we learned to appreciate pretty things because we appreciate the human form for reproductive reasons. For example, we lie symmetrical faces better than others. There are many features of the human body, so symmetry must be only one of many features we appreciate. The sum effect on a person of all the little things we appreciate about a person determines whether we think they are good or bad looking. Those beauty judgments work looking at a mate, a dog or art.

    From the same section you cited on your Wikipedia/entropy link: "Entropy is a measure of thermal energy per unit temperature that is not available for useful work."

    Okay, I actually just now noticed you claimed that I misunderstood the research, although I had long ago, responded to a message including your claim on my supposed misunderstanding. 

    Here's a bit more on why your quote above is reasonably false, and why the OP is likely valid, at least contrary to your criticism. (Ironically, reasonably due to your misunderstanding!)

    1. When the brain is unconscious, data shows that less "work" is being done. 
    2. When the brain is conscious, data shows more "work" is being done.
    3. As the very section on the very page you cited reveals:
      1. Entropy may be observed as a measure of disorder, or measure of inherent loss of usable heat.
      2. The more "work" the brain does, the less heat or energy is available for work. 
      3. This is why the farther away from sleep, and the closer to a conscious state the brain approaches, the higher the value of entropy, or the more the loss of usable heat or energy for "work" or consciousness.
      4. Think of entropy like a currency; up until a point, the more work you are permitted to put in, the more entropy you have to "pay up" to your surroundings, in the form of unusable heat or energy. This reasonably means in the unconscious state, you have less unusable energy at your disposal (or more usable energy, or lower entropy), compared to conscious states where you have used up your energy, thus more unusable heat or energy exists. (i.e. higher values of entropy)


    A statement from the paper: "We find a surprisingly simple result: normal wakeful states are characterised by the greatest number of possible configurations of interactions between brain networks, representing highest entropy values".

    Another statement from the paper: "Note how during wakefulness the entropy is closer to the maximum of the curve, whereas the deeper the sleep stage, the more distant from the maximum the values are".

    So, the paper I originally cited along with what I underlined in the OP is reasonable, at least contrary to your criticism, and it is simply likely that you misunderstand the general idea behind entropy. In other words, your quote above regarding entropy and the unconscious brain is "not even wrong"!


    Sleep is confusing, because sometimes the brain is very active during sleep; while not conscious, unconscious does not necessarily mean sleep. Let's consider unconscious to be brain dead or in a coma.

    The higher the temperature, the more usable heat energy is available for work. The lower the temperature the less energy available for work. Is it untrue that a high temperature mass produces more [math]\Delta[/math]S, but the mass at high temperature has less entropy than the same mass at low temperature.

    I think I figured it out. The more molecules vibrate the higher the entropy. Also, the more disperse molecules are the higher the entropy. However, I think of the Sun as having lower entropy than deep space; is that false.

  14. I am liberal, but changed from a conservative. Here is my reason. 

    I live in the US which purports to believe everyone is born with equal rights to life, liberty and the pursuit of happiness. Moreover, we are all children of Earth, along with all the animals. If we act like animals, then we ignore our fellow man and take food off their plate if we are hungry, chase them from a hunting territory, and let them starve if they cannot fight hard enough for to live. Conservatives seem to follow this reasoning; it was my reasoning when I thought I was conservative.

    However, we produce enough food on Earth to feed everyone. There is no reason anyone should be starving. We make fences and destroy habitats of animals and thereby have been destroying the natural world around us. Our release of CO2 and methane threaten to cause a mass extinction from which no man can survive. Conservatives in my country, seem hell bent to commit suicide, by denying climate change, spoiling natural habitats, and poisoning the water. Conservatives have been opposed to raising the minimum wage, which in my opinion destroys the economy. My reasoning is to consider the lowest possible wage $0. If the masses have no money to spend, the economy is toast. Factories will close. People will suffer. Thus, I am liberal.

    • Thread title: "Consciousness causes higher entropy compared to unconscious states in the human brain".
    • The title for this thread aligns with the researchers' words: "We find a surprisingly simple result: normal wakeful states are characterised by the greatest number of possible configurations of interactions between brain networks, representing highest entropy values".
    • And for several years now, I'd been aware of that nao robot "self-awareness" test, that uses deontic calculus as far as I recall.

    Consciousness results in greater brain activity than unconsciousness. in fact, unconsciousness can be caused by low blood flow to the brain. My understanding is that there is greater blood flow in the brain than during unconsciousness, which means the grain is using more energy during consciousness than when it is unconscious. According to Wikipedia's Entropy article, Entropy is inversely proportional to temperature. Thus, higher entropy would indicate an unconscious brain.

    Shannon entropy is supposed to be analogous to thermodynamic entropy. Thus, your title seems incorrect; thus, it confuses me.

    I find it odd that you simply took "Strange's" words as valid, without thinking about the problem yourself.

    Strange is shown to be wrong above.

    I didn't just take Strange's word. I may be mistaken. Your title for this thread seams misleading to me, even if the researchers didn't make any mistakes. Moreover, I don't believe that consciousness is a side effect of entropy. Here is a report of a conscious robot.

  17. A recent report on TYT (re: youtube How AI Is Being Used To Create Fake Porn) says AI systems are available on the internet with instructions telling novice users, ones with no programming experience, how to use the AI. Furthermore, someone has created a video editing system that allows the person to trade faces in the video for one in a picture. Thus, anyone may show up in a porn movie. Not good.

    Adolescents will grow up developing AI and some of them will do good things. Of course there are serious developers using AI, too. It is good to know how easy it is to use AI.

    I think everyone needs to now about this technology, Forewarning perhaps can lessen the shock of seeing oneself in a compromising situation.
