1 00:00:04,070 --> 00:00:02,629 in some sense there is no Theory of 2 00:00:07,130 --> 00:00:04,080 Everything 3 00:00:10,850 --> 00:00:07,140 right any formal system that is Rich 4 00:00:15,169 --> 00:00:10,860 enough to model the axiom's arithmetic 5 00:00:16,730 --> 00:00:15,179 is is either inconsistent or incomplete 6 00:00:18,529 --> 00:00:16,740 and we call it girdles in completeness 7 00:00:21,529 --> 00:00:18,539 theorem because we don't take the 8 00:00:23,929 --> 00:00:21,539 inconsistency thing too seriously so 9 00:00:27,650 --> 00:00:23,939 that means no matter what 10 00:00:30,410 --> 00:00:27,660 scientific theory we have 11 00:00:32,210 --> 00:00:30,420 it's not the final word there'll always 12 00:00:34,310 --> 00:00:32,220 be if the if the theory is Rich enough 13 00:00:36,170 --> 00:00:34,320 to do arithmetic and most scientific 14 00:00:37,670 --> 00:00:36,180 theories are they wouldn't be taken 15 00:00:38,990 --> 00:00:37,680 seriously so they're rich enough to do 16 00:00:42,110 --> 00:00:39,000 arithmetic so they're rich enough to 17 00:00:45,110 --> 00:00:42,120 have a girdle statement that that is
