A year or so back I was forming baby       >>>>>>>>>>>> problems in a       >>>>>>>>>>>> blog       >>>>>>>>>>>> for a Linux newsgroup frequenters to solve, and in one of       >>>>>>>>>>>> them one       >>>>>>>>>>>> would       >>>>>>>>>>>> begin with a correct equation, would make correct changes in       >>>>>>>>>>>> it,       >>>>>>>>>>>> but       >>>>>>>>>>>> would end up in an obviously wrong equation :) Nobody solved       >>>>>>>>>>>> it of       >>>>>>>>>>>> course (audience were mostly morons). But I now wonder if that       >>>>>>>>>>>> problem       >>>>>>>>>>>> had something about Kosmanson's concerns about handling       >>>>>>>>>>>> infinities.       >>>>>>>>>>>>       >>>>>>>>>>>> Here I quote the part of the blog that contained that problem:       >>>>>>>>>>>>       >>>>>>>>>>>> (beginning of the quote)       >>>>>>>>>>>>       >>>>>>>>>>>>       >>>>>>>>>>>> "Then, swoooooooshhshsh!.... and Jesus and all that intense       >>>>>>>>>>>> light       >>>>>>>>>>>> went       >>>>>>>>>>>> back up and out of there.

Last time he had eaten anything was the night before       >>>>>>>>>>>> he had       >>>>>>>>>>>> waken up on the summit of the magic mountain in an urban Dallas       >>>>>>>>>>>> area.       >>>>>>>>>>>>       >>>>>>>>>>>> He thought to himself, "I'm going to assume that more than 48       >>>>>>>>>>>> hours has       >>>>>>>>>>>> passed since.

There was nothing there but the cat food he had       >>>>>>>>>>>> cooked on       >>>>>>>>>>>> the day he first saw the magic mountain.

After choosing the closest       >>>>>>>>>>>> to a       >>>>>>>>>>>> healthy       >>>>>>>>>>>> nice pre-agricultural food kit, he clicked, "Go to checkout"       >>>>>>>>>>>> button,       >>>>>>>>>>>> after which the computer waited for a few seconds but       >>>>>>>>>>>> instead of       >>>>>>>>>>>> getting       >>>>>>>>>>>> to the check out screen, a screen came up to make sure       >>>>>>>>>>>> Physfit was       >>>>>>>>>>>> not a       >>>>>>>>>>>> robot. It had a simple question that he had to give it the       >>>>>>>>>>>> correct       >>>>>>>>>>>> answer, otherwise food nommo.       >>>>>>>>>>>>       >>>>>>>>>>>> The question went like this:       >>>>>>>>>>>>       >>>>>>>>>>>> "In math, is there a difference between the two numbers       >>>>>>>>>>>> 0.999999...       >>>>>>>>>>>> and 1 ?"       >>>>>>>>>>>>       >>>>>>>>>>>> The digits of "9" continued forever to the right of the radix       >>>>>>>>>>>> point. So       >>>>>>>>>>>> of course, Physfit clicked on the "yes" button.

(first of the fix number of curses       >>>>>>>>>>>> Jesus had       >>>>>>>>>>>> allowed him for that day). So he took a pen and paper and       >>>>>>>>>>>> started       >>>>>>>>>>>> jotting down:       >>>>>>>>>>>>       >>>>>>>>>>>> x = 0.99999....       >>>>>>>>>>>>       >>>>>>>>>>>> Therefore:       >>>>>>>>>>>>       >>>>>>>>>>>> 10x = 9.99999....       >>>>>>>>>>>>       >>>>>>>>>>>> Now he subtracted the former from the latter:       >>>>>>>>>>>>       >>>>>>>>>>>> 10x - x = 9.99999... - 0.99999...       >>>>>>>>>>>>       >>>>>>>>>>>> Which simplifies to:       >>>>>>>>>>>>       >>>>>>>>>>>> 9x = 9       >>>>>>>>>>>>       >>>>>>>>>>>> And therefore:       >>>>>>>>>>>>       >>>>>>>>>>>> x = 1       >>>>>>>>>>>>       >>>>>>>>>>>> "What the fuck??", said Physfit (his 2nd curse of the day).       >>>>>>>>>>>>       >>>>>>>>>>>> Why x which was 0.99999... and not 1, turned out to be 1? ...
