The actual basis of mathematics is logic... applied to numbers. When we 'count' something, we are replacing an actual thing with a number, and then logically operating on the number NOT the thing itself. When we measure something like a wall, we use a ruler or some other measuring device which approximately converts the dimensions of the wall into numbers we assign labels of lengths to, we then operate on the numbers, NOT the wall.<br /><br /> In any case you can think of which involves anything with any actual physical extension in our reality, NONE of it can directly be operated on mathematically whatsoever. Everything must first be measured approximately and then represented numerically, and then it is those numbers which can be operated on mathematically. I dare you to try to apply numbers or mathematics directly to anything real. You can't. You must first construct your measured numerical model, then putz around with that, so you are always at least one level of approximated abstract representation away from the reality of what you are measuring.<br /><br /> Reality is actually the opposite of what Tegmark imagines, he gets the horse and cart badly confused. It is strange that one supposedly so brilliant exhibits such a poor understanding of the logic of causation, and can not discern between the difference between the abstract and the actual. Abstractions do not inform reality, reality informs abstraction.<br /> <br />All numbers only exist within peoples heads as ideas connected to symbols we use to represent them with. If you examine the computation of an abacus or an arithmetic logical unit, neither uses actual numbers at all, only physical things easily differentiated (like beads or higher and lower voltages, there are no 1's and 0's in binary computation) that we then abstractly group and label as numbers (once again, we convert the actual to the numerical abstract then logically operate on the abstract).CFTnoreply@blogger.com
