You can bar it from your universe if you like but it's in mine and you cannot take it away!

One got large enough for a kid to climb inside the box. ?????

So I'm about to take off the damaged bits and saw up new panels to replaced them. Hopefully one afternoon's work. Then someone else is going to paint them black.

]]>What do you need those for?

Hi bobbym

You should really look things up from time to time...

]]>Bob

]]>True, true.

What kind of tools?

Hi bobbym

Look the phrase up.

But what are the privileges of defining 0.999... to "exist" as a mathematical concept and be equal to 1?

That's my whole point. Anyone can have their own mathematics just by defining it. If it is consistent and useful, others may adopt it too.

If it isn't useful, others will probably just ignore it.

If it's inconsistent, then lots of folk will tell you so.

Whatever, nobody has to use it if they think it is odd, poorly defined or just they don't understand it.

We've had a few of those on the forum recently.
