  1. Re:The King and the Chalice (only for Experts!) on Your Favorite Math/Logic Riddles? · · Score: 1

    This problem is unsolvable

    If I am the King. I will just call each prisoner a required number of time in a row. Then return the position of the chalice before calling another prisoner
    for example:
    I call the first prisoner, then call that prisoner a million times and never call that prisoner again. After that return the chalice to the original position and call the next prisoner.I can do this k times (k number of prisoner) then that number of prisoner cannot leave any kind of information.
    Also you mention that the cell is soundproof but you never mention that its opaque
    is the chalice their only way of getting information?
    because even if they cannot hear anything if they can see what is going on inside the central room then the solution is easy

    Radioactive sources? like carbon 14 that is inside your body or the radioactive potassium inside a banana. Not all radioactive sources are dangerous.

  8. Re:Obvious solution on Batteries Becoming Limiting Step For Portable Toys · · Score: 1

    Then you should have read the article because the title is misleading. It's not about miniaturizing nuclear reactor. The battery is powered by betavoltaics which utilizes natural decay of beta emitters like tritium, Carbon 14 and the likes. It's safe because beta emission cannot even penetrate the skin. and it's very stable because emission is dependent on the elements half-life. And even living thing's have beta emitter's in them. Even you have carbon 14 inside your body.

  9. Re:um on Cell phones as Credit Cards · · Score: 1

    It's easy every transaction you need to input a PIN. Then when you lost your phone you report it to the service provider to freeze the account hopefully before someone can crack the PIN. It's even much safer than carrying real money with you.
