Willem F Esterhuyse Posted February 18, 2023 Share Posted February 18, 2023 Especially talk of infinities are mental constructs with no physical proof that they exist. Cantor proves the Reals are uncountable by constructing an infinite list of reals paired to a natural number. Such a list can be constructed conceptually in mind, but it cannot be physically produced to check that it exits. This is why I say mathematics is a Fairy Tale. -6 Link to comment Share on other sites More sharing options...

This appears to be a thread designed to "get under peoples skin". In other words you seem to be trolling, what is the point of doing that? 3 Link to comment Share on other sites More sharing options...

Moby Dick could've ended up with Ahab having Moby for dinner, or the other way. Cantor's diagonal theorem has only one possible ending: Its logical conclusion. Spoiler alert: Spoiler 'Call me Ishmael' doesn't tell you Moby-Dick kills Ahab and destroys the Pequod.

swansont Posted February 18, 2023 Share Posted February 18, 2023 ! Moderator Note Rule 2.12 We expect arguments to be made in good faith. Honest discussions, backed up by evidence when necessary. Example of tactics that are not in good faith include misrepresentation, arguments based on distraction, attempts to omit or ignore information, advancing an ideology or agenda at the expense of the science being discussed, general appeals to science being flawed or dogmatic, conspiracies, and trolling. Nebulous claims such as this do not make for a good-faith discussion Link to comment Share on other sites More sharing options...
