    Zero 0 is an EVEN number which lies between -1 and 1

    This was stated on QI but sorry unable to give a more exact reference

    But Google gives up the following Wiki

    Why zero is even

    The standard definition of "even number" can be used to directly prove that zero is even. A number is called "even" if it is an integer multiple of 2. As an example, the reason that 10 is even is that it equals 5 × 2. In the same way, zero is an integer multiple of 2, namely 0 × 2, so zero is even

    Unless my eyes deceive me (or my glasses - I'm due a new pair in 2 months) I detect a 0 between -1 and 1 in the line image from the referenced article

    Hope this helps all

    I corrected your "correction". If you still don't understand, it seems that everybody else does.

    That's funny. I was giving you the benefit of doubt among other benefits.

    I definitely understand.

    SiaSL: you have now posted 6 responses in a row that are entirely evasive (did you think we wouldn't notice?)
    You made at least one assertion among others - that nothing exists between 1 and -1.
    Several people have questioned what you mean by this, since it is demonstrably false. But we gave you plenty benefit of the doubt - and plenty of opportunity to correct/clarify.

    Yet you have offered no clarification in any subsequent posts, except to assert (falsely) that you've tried to explain.

    At this point, we are justified in interpreting your evasiveness as 'I said a dumb thing, and now I don't know how to retract it.' Let's just leave it at that and move on.

    I have only countered ridiculous assumptions that I am confused & do not understand. That is not evasive. Neither is telling you there is nothing more to say. I had my say & others have had their say including repeating several things. It is obvious neither will convince the other.
    A person should be able to stop discussing something without undue assumptions being made. I have often been tempted to stop a discussion with you.
    "I tried my best to explain it to you." was to sideshowbob about what we were discussing & it was not false. It is quite foolish for someone else to claim they know I did not try my best to explain.
    No. That is not justified but you believe whatever helps you.
    I am obviously trying to move on. I do not care much for bantering with the devil or his advocate. I have no idea whether you are serious & at this point, I do not care.

    I find it incredible that this Thread now has 166 Posts (not including mine).

    I have only read a few. I can find more interesting issues on which to waste time.

    And yet you have time to waste telling us that you have no time to waste.

    In my 73 years of observation, I have found that when a clock reaches 12:00, the time is said to be 12:00 a.m. This, therefore, is the first second of the new day, not the last second of the previous day.

    Computers have institutionalized this, since today, most clocks are electronic and cannot be re-set easily, if at all.

    12:00 is midnight, which is not really 12:00 in engineer's terms, so it really doesn't exist since the longer the decimal, the farther away from it's actual meaning it gets an the further away, the smaller it gets. Plus, it never really is midnight anyways since time is congruant and doesn't really split up into sectors.

    12:00 is a zero-duration event.

    You're referring to the first second after 12:00.

    Here's a logical argument that shows your idea can't be right:

    Why did you pick a second for the duration of the time you call 12:00?
    Why not a minute, and hour or a microsecond?

    12:00 can just as easily refer to the first minute after midnight, 12:00 can also be the first hour. Or the first nanosecond. How could such a broad and arbitrary array of durations all be referred to by the same label?

    No. 12:00 must be a zero duration event - before the first second - before the first nanosecond of the new day.

    Or 11:00 ... 00:00
    Or 11:59 ... 00:00
    Or 11:59:59.999 ... 00:00
    Or 11:59:59.999999999 ... 00:00.

    Exactly!!!! so the question really is, "do we ever really get to midnight?" and if we do, do we let it all hang out? or jump scream and shout?

    We do, instantaneously. Then it's past.

    The other thing is that midnight happens at different times because of time zones. But really all there is is one long block of time from the beginning of reality only seperated by light times and dark times.

    IMO, Midnight, the arbitrary moment when today turns into tomorrow, may be compared to a quantum event, the change from one named state in time into another named state in time.

    Lets go deeper than quantum

    What does that have to do with quantum events? Classical states change all the time.

    I specifically qualified it as an arbitrary moment, and only compared its duration of change to a quantum moment, which as far as I know, is an even smaller time interval than the caesium time standard, which for human purposes is the most accurate time standard.
    https://en.wikipedia.org/wiki/Caesium_standard

    It seemed theoretically appropriate to use a quantum moment. Just trying to keep it simple.
    IMO, time itself is an emergent property and continuous only in respect to Bohm's Pilot wave.
