[FAROOQ95123]

3 dislikers didnt understand

[rohitsetia]

same old typical indian way of teaching prevalent in all over india and exactly the same boring, unintuitive, student unfriendly, dull. But exceptionally innovative work done by posting this on youtube.

[aliwalayweb]

only 3 dot ... are general rule .

[khalifamak123]

To Prof. Kamala, I studied computing at university of London, your conduction is a rare , great and very clear lecture , . Pls keep producing such work for desperate students from around the globe, Thanks again and always

[rogeramolato10]

[theboombody]

Good old paradoxes. They keep things interesting.

[chintanbiz]

A great lecture again by Kamalamem... Thanks a lot...

[rafaelcapucho]

bad english...

[chintanbiz]

@rafaelcapucho Are you for math classes or for English?? Plz decide... :D

[sexy19081995]

kya yaar...tym waste

[Kurtlane]

Here is where I am confused:

The explicit definition of a set is unlimited as to what can go in there. For example, I can have a set S1, defined as {mommy, daddy, grandpa, window and 11:30} (as one little girl said).

However, induction definition doesn't allow such liberties, so that while I can have a set S2 of well-formed strings of parentheses, I cannot have a set S3 of well-formed strings of parentheses and a window.

(cont.)

[Kurtlane]

This is odd. Why can't I have it? And what if I create a set S4, which includes set S2 and a window? Is that allowed?

[albertbeccu]

Great! Thanks for a great lecture!

[mosgba]

it's a good place she started to me. weldon

[mrperfectprashant]

people she is from iit the best engineering college of world.

[MsMystery92]

i cnt understand a word she is sayin!..how is she supose to help me!!!!! WTF!!

[23davidbeckham07]

it sounds like she said ''2day we'll talk about sex!'' hahahahahahahahhahahahaa..

[drunite]

and you picture yourself having sex with her didn't you, you dirty cunt.

[EezzyAK]

The starting is funny crack!! Reminds me of those ancient times in civilization game.. Anyways it helps.. Cool vid!!

[LuuzerHarris]

lololololol

[tariqraza110]

[LuuzerHarris]

This confirm help me... LAUGH. LOLOLO

[23davidbeckham07]

WTF!!! (for the song at the begening)

[imydaking]

its a religious thing for them man

[23davidbeckham07]

ya but last time i checked that was a maths video! lol

[ElgnubRm]

20:00 <- Just a note to myself. Thanks for the video btw. NPTEL rocks.

[chordsequencer001]

by definition of "sets" and "members of sets" what the he** kind of set would contain itself in the first place???

I think Russell was drinking or something because it seems like the meaning of "set" and "elements" are CLEARLY two DISTINCT things (concepts)...someone fill me in on this.

[ElgnubRm]

The set of all sets would contain itself. But still I think that using levels as the teacher said would solve the paradox. A set would contain a different version of itself but never itself. I can't even imagine such thing it doesen't surprise me that it leads to a paradox.

[ananihdv]

she has not talked about power sets

[3rdEarlRussell]

@chordsequencer001 Responder a este vídeo... There's no incompatibility. Sets can me members of sets too. In fact, in ZFC set theory, there are no non-sets, every member of a set is also a set. Only set theories with urelements have objects that aren't sets at the base level, but in them also sets can be members of sets.

[theboombody]

@3rdEarlRussell Does that mean something can be twice as big as itself?

[mk60068]

I am a teacher, but my logic education as an undergrad. only involved Aristotle and some very basic symbolic proofs of validity and proofs involving quantifiers. I need to pick sets, etc., up on my own, and with Dr. Kamala's help

I may just be able to grasp the various books on the subject. Why doesn't a US school put out material like this?

[miguelcotto4ever]

Thats because American schools pay their teachers to show up to class and teach governement propoganda. Not teach you to succeed!

[aflrunner]

Perfect Explanation !

[himanshupatel79]

This is very USEFUL , Now i feel that i can pass this subject

[calculus100]

very good
