00:00:00Hello friends, yeah welcome to Friday Night Live Punky Lily episode 171.4.
00:00:09Okay, uh, martial arts?
00:00:13Sure.
00:00:14Let's do jump side kick, okay?
00:00:17Hyah!
00:00:18Hyah!
00:00:19Hyah!
00:00:20Hyah!
00:00:21Okay?
00:00:22Jump side kick.
00:00:23Good, good.
00:00:245 minutes break please, thank you.
00:00:28Ooh, good exercise there.
00:00:31Mm-hmm.
00:00:36Okay.
00:00:41Hut!
00:00:57Mm-hmm.
00:01:28Good.
00:01:43Mm-hmm.
00:02:27you
00:02:57you
00:03:27you
00:03:57you
00:04:27you
00:04:57you
00:05:28you
00:05:50you
00:05:57you
00:06:04you
00:06:16you
00:06:27you
00:06:57you
00:07:07you
00:07:27you
00:07:58you
00:08:08you
00:08:16you
00:08:21you
00:08:27you
00:08:37you
00:08:45you
00:08:58you
00:09:08you
00:09:18you
00:09:28you
00:09:38you
00:09:57you
00:10:03you
00:10:08you
00:10:14you
00:10:27you
00:10:58you
00:11:08you
00:11:16you
00:11:27you
00:11:33you
00:11:38you
00:11:46you
00:11:52you
00:11:58you
00:12:03you
00:12:08you
00:12:16you
00:12:21you
00:12:28you
00:12:33you
00:12:57you
00:13:27you
00:13:57you
00:14:14okay so some safety scenario here uh if this shooter is not too far away not too close
00:14:24what kind of intermediate distance uh i can throw things at him okay uh there's one possibility or
00:14:33take cover yeah like hide some behind the wall whatever okay yeah some barricades
00:14:44behind the furniture like uh and then and then move away right sometimes silently sometimes
00:14:53where so hiding and then but don't be a sitting duck though yeah move away slowly maybe silently
00:15:00okay yeah well but the thing is this okay i'm not an expert in this okay i was in the u.s army but
00:15:09i was not in infantry okay so uh maybe in youtube yeah probably they can teach you way better than i can
00:15:16okay yeah
00:15:23like safety training oh yeah like police officers right yeah they're the experts so
00:15:32oh they can teach way better right okay yeah
00:15:36um
00:15:42but martial arts okay so
00:15:48anything here can be used as much of a weapon like cups chairs what objects
00:15:59even this jacket too okay yeah can be used as much as well so
00:16:10yeah so more safety lesson yeah i refer to youtube okay yeah because i'm not expert in that
00:16:23now yeah you can get back to mathematics i think i took enough break
00:16:27okay let's go to wikipedia and uh there's this theorem that's already proven by other people
00:16:35uh quite challenging one okay so uh and i did not see other people's proof i don't want to see it
00:16:47but we prove it ourselves because even interesting although it's already proven okay
00:16:58so
00:17:02i look for knuth professor knuth
00:17:27um possibly this one
00:17:39it's about fraction
00:17:48this right caution yeah
00:17:58yeah we kind of independently discover something like this okay something like that right and um
00:18:16okay
00:18:28let's grab whiteboard and let's prove this thing
00:18:40sure
00:18:47it's quite a formidable problem there
00:18:57you
00:19:27uh
00:19:42yes we use this one okay
00:19:50okay let's erase this okay
00:20:07oh
00:20:20so
00:20:30so
00:20:49okay
00:20:54so the equation says
00:21:24okay
00:21:32okay
00:21:40all right now let's just look at the easiest case when n is one
00:21:49okay
00:21:49n is one
00:22:20okay
00:22:32you approve this go for it okay yeah
00:22:37hint uh you scroll out theorem okay yeah
00:22:44all right yeah five minutes thank you
00:22:49uh i think we proved krull theorem before
00:23:05yeah i'm pretty sure let me look for it uh cross here i'm going to prove that thing
00:23:19you
00:23:25yeah we did prove it
00:23:29okay five minutes okay thank you
00:23:35okay if you want to prove it go for it okay all right
00:23:49you
00:24:19you
00:24:49you
00:25:19you
00:25:49you
00:25:55okay
00:26:04cheers
00:26:10yeah
00:26:11okay
00:26:16let's go for it okay this one's easy okay so left hand side using cross
00:26:31and integer close out
00:26:36okay
00:26:41okay right hand side
00:26:53m closed out okay and then context and theorem okay
00:27:03which is left hand side okay good
00:27:08qd
00:27:11okay so that's when n is one that's easy enough
00:27:19now let's prove this when n is two okay
00:27:41you
00:27:51okay uh in order to prove this we may need to prove some other stuff first as we go along okay
00:28:01now uh this is tricky okay uh we kind of like independently rediscovered this
00:28:11in the context of like uh bezoo coefficient okay yeah cheers yeah
00:28:21okay
00:28:28now let's make some concrete examples
00:28:36let's take the case when m is zero
00:28:41okay
00:28:42you
00:29:08okay yeah
00:29:12prove easier cases first
00:29:20step by step little bit of time okay yeah cheers
00:29:42you
00:29:52all right do you want to prove this go for it okay yeah well i have an idea
00:30:00yeah hint x is equal to baramax plus collie x that kind of methodology
00:30:13works so many work for us so many other proofs so i think it will work in this case too okay
00:30:23how nice huh cheers this is fun
00:30:31yeah five minutes okay thank you you'll prove this go for it okay
00:30:43having fun with mathematics nice
00:30:48five minutes thank you
00:31:00you
00:31:30you
00:32:00you
00:32:30you
00:33:00you
00:33:31okay so fortunately i have never been in a math student situation but uh one incident like
00:33:43yeah it was not a real bullet there's this guy driving his car like just outside his house
00:33:52okay on the road and he was like i think it's a blank maybe it's really going to the blanks
00:33:58but not the real bullet yeah he was driving and like making noise with that maybe fake gun or
00:34:05real gun with the blanks not real blood okay something like that he was making noise okay
00:34:12driving his car right and i did not run i did not hide i stood still why because i don't i did not
00:34:20think he would shoot me okay and uh me honky lee yeah i regard myself as god's prophet so charisma
00:34:30and yeah uh i made eye contact with him okay i thought i can calm him down okay yeah i didn't
00:34:40think he would shoot me it was like right outside this house i was taking a cigarette actually okay
00:34:48yeah
00:34:52i don't think it was real blood maybe blank or fake gun he was just making popping noise okay
00:34:58driving his car but i don't think he shoot me
00:35:05and did he point his gun at me i don't think so yeah it was like driving his car making noise
00:35:12and later on uh i heard some police of police cars with sirens
00:35:20so i guess somebody called 9-1-1 and arrested him
00:35:27i think so
00:35:32but i don't think it was real blood okay i think it's blanks maybe
00:35:42was i afraid no
00:35:46i wasn't
00:35:54good i practiced martial arts i know real danger i can tell between real danger and fake danger
00:36:04because i'm martial artist
00:36:06huh yeah i could tell uh this guy is not a dangerous person
00:36:15okay
00:36:20yeah i will tell
00:36:26yeah
00:36:28you
00:36:32now
00:36:35let me start drinking okay
00:36:38okay
00:36:44okay
00:36:57you
00:37:07some stories you approve this go for it okay uh when i was in the u.s army okay um i just my army
00:37:18colleague
00:37:20for good texas uh he told me this story
00:37:29that actually happened in texas outside the base highway who's driving the highway
00:37:39and he changed the lane
00:37:43and the driver behind him got very angry
00:37:51so basically like
00:37:56the driver behind my friend maybe made some gesture yeah stop your car i want to talk to you
00:38:03basically quick okay so my friend stopped his car i was not there he told me the story after
00:38:08he told me the story after that happened okay so he stopped his car and my friend and the driver
00:38:16behind his car stopped his car and then he came with a handgun and pointed at my friend
00:38:26my friend was very calm he was like hey what's going on he said and the other guy said you caught me
00:38:35like you see the land right in front of me and my friend said oh i'm sorry but
00:38:47okay so he calmed him down so and the guy with the gun went back to his car and drove away
00:38:59true story yeah yeah
00:39:05yeah my friend being very mature calm person was he afraid no
00:39:16okay sometimes it worked that way
00:39:22sometimes not always okay so yeah love majors okay yeah it's important
00:39:28important
00:39:32and believe in god
00:39:39oh yeah i don't go to church but i do believe in god okay
00:39:47okay
00:39:51now
00:39:59let's have five minutes okay five is very good thank you
00:40:14okay five minutes thank you
00:40:19um
00:40:25there we go okay
00:40:49you
00:41:19you
00:41:49you
00:42:20you
00:42:20you
00:42:42okay uh let's do some hypothetical scenario
00:42:48okay uh purely hypothetical i'm not recommending this just hypothetical okay
00:42:57uh
00:43:01actually actually happened actually uh
00:43:06so like 9 11 uh over somewhere in pennsylvania uh the passengers when um
00:43:17the terrorist with uh box cutter that's like small knife okay uh they work together and then
00:43:25put down those terrorists okay it actually happened now in a shooter mass shooter situation
00:43:35let's say there's one gunman with also rifle or handgun okay but if 10 or 20 people
00:43:44people jump at him or at the same time then it's possible to neutralize that gunman
00:43:55because 10 20 people jumping at him or at the same time
00:44:01then yeah it's possible to neutralize it okay again pure hypothetical here okay
00:44:10okay
00:44:14okay
00:44:17now
00:44:21let's do this okay
00:44:26you ready let's go
00:44:33yeah
00:44:45you
00:44:47x is part of x plus coli x
00:45:15okay
00:45:26yeah uh
00:45:45you
00:45:56let's make some examples here
00:46:04uh
00:46:08let's say x is 1.5 okay
00:46:14okay if x is 1.5
00:46:23this is 1 and this is 0.5
00:46:31okay
00:46:31okay
00:46:43okay
00:46:55you
00:47:01now
00:47:05yeah we need to prove something intermediary lemma okay so let's say
00:47:18um
00:47:25you
00:47:37well
00:47:55you
00:48:15let's say x is like 1.7 okay
00:48:181.7 0.7
00:48:352.4 so 2 that's not the same as 1.7
00:48:42um bottom which is 1 okay okay so this that's not true okay okay
00:48:53yeah
00:49:12you
00:49:34now if x is 1.7
00:49:43you
00:49:56it is yeah double zero
00:50:00uh this is tricky ah yeah
00:50:03yeah
00:50:10i don't know how to prove this
00:50:14not yet
00:50:33you
00:50:39handshake oh boy
00:50:51it's been less than one hour okay all right so
00:51:03you
00:51:33you
00:52:03you
00:52:03you
00:52:04you
00:52:04you
00:52:32no
00:52:34you
00:53:04you
00:53:34you
00:53:55let's have violence bro okay
00:54:00it's confusing
00:54:04you
00:54:18what
00:54:19you
00:54:32when m is zero and n is one
00:54:39you are saying
00:54:49you
00:54:55well that's quotation theorem but
00:55:00x is equal to bottom x plus coli x okay
00:55:07you
00:55:17through our theorem
00:55:30uh this is zero
00:55:31you
00:55:35okay well good to know okay
00:55:41let's say five minutes okay thank you interesting
00:55:51yeah five minutes thank you
00:55:57okay
00:56:01you
00:56:31you
00:57:01you
00:57:31you
00:58:01you
00:58:21okay
00:58:31you
00:58:56well so let's take a break from mathematics get some story time when i was in high school
00:59:0211th grade okay yeah so that's korea uh there was like what year was that
00:59:111995 yeah i was vice class president not class president vice class president all boys school
00:59:22we were about 50 students per class okay and but i was very selfish i just studied
00:59:31i didn't take care of other students well i can't do that actually but still selfish just studying
00:59:40so uh this guy later on we became very good friends because he was upset with me and uh
00:59:50so
00:59:50in front of everybody he roundhouse kicked me i was sitting on my chair okay
01:00:05he told me yeah take off your glasses i was like why
01:00:09and then he took off my glasses with his own hands and i was sitting on a chair desk right
01:00:17classroom then he kicked me roundhouse yeah
01:00:27did i fight him back no i didn't because he just stopped there
01:00:33i didn't say anything he just walked away
01:00:40so but looking back
01:00:41back now i say good kick man good kick yeah
01:00:49i guess i can't deserve that okay so i didn't fight him back
01:00:52i was too selfish yeah i i deserve that it's good kick yeah good no no broken tissue no injury
01:01:01anything no just i'm used to it you know look i i i'm trying to tackle though yeah we kick each
01:01:08other all the time so no problem cheers yeah later on we became very good friends okay no problem
01:01:19good kick okay well don't get as wild okay yeah now uh
01:01:27simple one
01:01:49you
01:01:49you
01:01:50you
01:01:50you
01:02:16who you saying
01:02:21you
01:02:40how interesting
01:02:51you
01:02:57uh
01:03:00how about this
01:03:09you
01:03:15we know that because x is equal to bottom x plus coli x by definition yeah we know that
01:03:39you
01:03:52oh
01:04:09you
01:04:30it's been so far
01:04:40cheers
01:04:53let's say final spirit okay
01:04:57i don't know how to do this
01:05:03yeah
01:05:03uh
01:05:08so yeah learn martial arts also if it's legal for you in your locality yeah learn how to shoot a gun
01:05:18too safely legally like your shooting range okay yeah also uh learn how to use weapons like dagger
01:05:28but safely like butter knife blunt or you can use chopsticks pretend it's table okay knife okay
01:05:37yeah martial weaponry very important yeah belt right it's like whip yeah you don't have to use
01:05:45those two okay yeah rod staff yeah martial arts okay yeah you don't have to use those
01:05:55yeah but don't get it to fight right yeah okay
01:06:03yeah sparring is fine safely okay yeah okay five minutes okay thank you
01:06:10this is top cookie ah wow but good challenge yeah
01:06:17okay five minutes thank you i'm interested
01:06:47you
01:07:17you
01:07:47you
01:08:08okay well some story time sure
01:08:12sure let's take a break from mathematics okay so when i was in the u.s army for who text us okay
01:08:19uh yeah mandatory form okay it's mostly guys like not u.s army back then i don't know about now
01:08:27it's like 95 guys males okay yeah so mandatory form yeah like sometimes
01:08:37company level battalion level and uh with our sergeants commissioned officers and uh
01:08:46and our army colleagues and uh we get together and uh uh mandatory form is it's like boxing match
01:08:56no gloves no just bare fist
01:08:59so our superiors asked for two volunteers boxing match okay uh so two african-american gentlemen
01:09:08okay my colleagues okay yeah junior enlisted okay volunteered boxing match bare fist
01:09:21bare fist
01:09:26yeah they're like this right pugilism right and then um
01:09:34two african-american gentlemen okay my colleagues and one of them
01:09:38landed a punch to the other guy and the other guy was like really
01:09:46but he stopped there because it became too emotional so basically he was like no i'm not gonna
01:09:54fight you man
01:09:57let's stop so that was that but if you get too emotional you know uh no i'm not gonna fight you
01:10:03man what a gentleman right so yeah he walked away what a gentleman okay
01:10:10what a gentleman okay
01:10:13true story yeah
01:10:21yeah now let's get back to this
01:10:27uh
01:10:39let me do the song okay
01:10:57uh i guess i don't mix fruits okay so let me separate this
01:11:07rose hips and high bush cranberries
01:11:12just that okay now two fruits separated let me wash my hands
01:11:27so
01:11:44yeah u.s army mandatory form right yeah sometimes dancing okay yeah
01:11:51um
01:11:53oh yeah
01:12:04sometimes martial arts okay
01:12:09yep
01:12:21um
01:12:36yeah
01:12:47yeah i want to drink some okay so because
01:12:52this this is nice problem to solve it's challenging and we may need to prove some
01:12:58lemmas intermediaries and uh yeah as they come along and yeah
01:13:17wrong bottle again
01:13:22um you did similar in color y'all you know rosy
01:13:30let me wash my hands again
01:13:43um
01:13:47yeah
01:13:52so in shooting situation they do lockdown right they shouldn't do that
01:13:58mass shooting situation they do lockdown no what they should do evacuation that's what they should
01:14:04be doing okay you know mass shooting situation evacuation okay yeah no lockdown no police
01:14:11officer they need to get into the building right so no lockdown evacuation they should unlock all
01:14:17the doors so that because shooters are already inside the building right yeah evacuation that's
01:14:25what's necessary okay lockdown no police officer need to get into the building you know okay
01:14:33okay
01:14:37now oh this let's say five minutes okay i used to work for this
01:14:46tough cookie this one is but it's good yeah we like challenges sure five minutes thank you
01:14:54yep
01:15:03okay
01:15:24you
01:15:54you
01:16:24you

01:17:23okay
01:17:26let me drink some okay then look at this together now time check
01:17:41it's been more than one hour okay
01:17:49yeah
01:17:50now the right bottle i will scrub very okay
01:18:02nice
01:18:07cheers happy labrador again happy sunday afternoon yeah
01:18:20you
01:18:50you
01:19:20you
01:19:50you
01:20:20you
01:20:50you
01:21:02wow i'm confused
01:21:06cheers
01:21:20you
01:21:29how about this um
01:21:40on intermediary okay
01:21:51x divided by two
01:21:56what will be the relationship between x over two bottom and just x bottom
01:22:12what will be the relationship between the two okay is it like
01:22:20you
01:22:25can the denominator can you just scroll out
01:22:41when x is one this is zero x is one is 0.5 maybe it's this
01:22:50you
01:22:52okay
01:22:56now let's go to wikipedia if and see if they have something like this
01:23:03okay it's a hypothesis okay sure
01:23:19ah
01:23:42okay there's some stuff
01:23:48you
01:24:08but not exactly what we want to
01:24:19okay
01:24:37oh that's interesting
01:24:40okay
01:24:45so
01:24:48you
01:25:18you
01:25:22when x is three this is one
01:25:29this is one two okay okay
01:25:44you
01:25:46okay let's define this graph okay and then uh
01:25:55this seems to be true okay
01:26:00yeah you want to prove or disprove this hypothesis
01:26:03conjecture go for it okay let's define this graph
01:26:06yeah
01:26:11okay yeah all right good we're making progress here slowly yeah
01:26:19okay five minutes thank you
01:26:27okay very cool

01:29:38you
01:30:09you
01:30:17uh we have the same problem as this okay okay good good good so most likely this should be
01:30:26true okay because some other people already proved this okay good now if we prove this
01:30:35then we can prove this we'll get equivalent problem okay nice good
01:30:45very cool
01:30:52oh this is when m is zero okay
01:30:59it's better case of this okay
01:31:01yeah cheers yeah
01:31:25now let's take a graph of mathematics okay so uh i read the wikipedia article about the
01:31:30columbine incident okay so uh the criminals there uh they were kind of nerdy geeky guys
01:31:40who love computers not very athletic so they hated high school athletes yeah two criminals
01:31:49in columbine incident they were high school students seniors like two weeks before graduation
01:31:55okay uh they hate they were bullied by athletes high school maybe football star
01:32:02uh so they became very angry after they were bullied by athletes high school athletes okay so
01:32:10uh they are not athletic themselves okay yeah they play with guns okay
01:32:21i am very sorry
01:32:25uh
01:32:29i'm a geeky nerdy guy myself i major in computer science okay yeah me look at me
01:32:35mathematics right but i'm athletic though yeah i do dancing martial arts running weightlifting
01:32:42okay yeah
01:32:49yeah
01:32:55yeah
01:32:59so in humanology it's about balancing act yeah we do geeky nerdy stuff like mathematics
01:33:05computers but at the same time we do exercise martial arts dancing running well lifting okay
01:33:15cheers
01:33:21yeah so it's about education okay now i need some vocal rest let's take five minutes
01:33:27okay so we found something you know which is very cool it's special test of that but
01:33:33this more uh fundamental level okay yeah
01:33:38after that then we get back to this okay but this we need to prove this one first
01:33:44and i do not know how to prove this yet okay
01:33:51so
01:34:07let's have five minutes okay
01:34:17okay

01:37:32yeah fractional zebra
01:37:37yeah there's some wikipedia article about this uh but uh relatively
01:37:47underdeveloped area of mathematics okay yeah relatively speaking okay so uh yeah so we are
01:37:55kind of like a rebuilding it okay yeah
01:38:01now
01:38:06uh
01:38:11i want some dragon drink
