[psikologi_transformatif] Re: please ajari matematika


> Apakah setiap operasi matematis yang melibatkan infinite hasilnya
jadi tak tentu, tergantung bagaimana pola di area finite-nya?
-------------------
Alexander:
Tidak semua jawaban tak tentu, ada yang jawabannya pasti juga.
Contohnya:
1. (infinite) + finite = infinite
2. (infinite) + (infinite) = inifinite

konsistensi operasi matematis?

Alexander:
Benar, banyak paradox muncul karena konsep infinite ini contohnya :
http://en.wikipedia.org/wiki/List_of_paradoxes

1. Burali-Forti paradox: If the ordinal numbers formed a set, it
would be an ordinal number which is smaller than itself.

2. Galileo's paradox: Though most numbers are not squares, there are
no more numbers than squares. (See also Cantor, Diagonal Argument)

3.Hilbert's paradox of the Grand Hotel: If a hotel with infinitely
many rooms is full, it can still take in more guests.

4.Skolem's paradox: Countably infinite models of set theory contain
uncountably infinite sets.

5. Supertasks can result in paradoxes such as the Ross-Littlewood
paradox and Benardete's paradox.

Alexander Agung
