    He won't be out, although he will be close enough.
    Comprehending Engineers - Take Two

    In the high school gym, all the girls in the class were lined up against one wall, and all the boys against the opposite wall.
    Then, every ten seconds, they walked toward each other until they were half the previous distance apart.

    A mathematician, a physicist, and an engineer were asked, "When will the girls and boys meet?"

    The mathematician said: "Never."

    The physicist said: "In an infinite amount of time."

    The engineer said: "Well... in about two minutes, they'll be close enough for all practical purposes."

    No, that is wrong. Division means how many times one number is contained within another number.

    Five is contained within 35 seven times, therefore 35/5 = 7.
    You can't answer how many times zero is contained within 35, therefore the answer to division by zero is undefined.

    How about 0/0?

    Are there 0 zeroes contained within 0 or 1? :P

    I did that calculation in Assembler on my Sinclair zx80 years ago and smoke started coming out of the back.

    There are 0 degrees today. Tomorrow it will be twice as cold.
    What's the tomorrow's temperature?

    You can't measure cold. You can only measure heat.

    Its like asking someone how small are they.

    No, there was no smoke, just a harmless infinite loop because you failed to check the parameters. There's no power saving or idle states in the Z80, so an infinite loop will use same power as anything else.

    OK then. There are zero degrees today, it will be twice as hot tomorrow. How many degrees will there be tomorrow?

    Zero degrees centigrade?
    It'll be 273 C tomorrow.

    It can't be twice as hot tomorrow , because it's fecking freezing today.

    The lowest temperature measured was about 50 picokelvin.

    Bleedin' freezin it was.

    1.

    dividing by 0 means the division didn't occur.

    1/2= 0.5, i.e. 2 equal parts that add to 1.
    1/4 = 0.25, i.e. 4 equal parts that add to 1.
    1/0 = 0.7 and 0.30 , i.e. 0 equal parts that add to 1.

    Of which there is an infinite number of answer or there is no answer :confused:

    I think doing it with apples is the most useful.

    Why not take advantage of the maths progression - starting off with 1 or 5 apples and ending up with 2 or 3 thousand apples. That’s a car load of apples.

    If you want progression you have to use pairs of rabbits.

    It's maths.

    Fahrenheit isn't a linear temperature scale, so your logic is broken.

    This is only true when you use a non standard definition of the equals sign (is associated with, rather than equivalent to).

    A maths teacher of mine gave a great explanation of dividing by zero.

    Imagine €12 on a table. And every time you go into the room you take €x. How many times would you need to go into the room before it was all gone?

    If you take €1 each time, you'd need to go in 12 times. If you take €3 each time, you'd go in 4 times. If you take €0 each time - you would never stop going in.

    It was an explanation of dividing by zero that stuck with me.

    Since when was substracting nothing equivalent to dividing by nothing?

    Your maths teacher was a retard.

    Then 1 * 0 = 1?
    Since the multiplication didn't occur?

    Nice.

    Meanwhile, there is a maths teaching concept called division as repeated subtraction, which you might find educational. Example: to find 45 ÷ 15, keep subtracting 15 from 45 until you hit zero. How many times did you do that? That's the answer: 3.
