00:00:00Hello friends, yeah, welcome to Humanology 2052.
00:00:10Okay, very cool.
00:00:12Let's start with physical therapy for my right shoulder.
00:00:19Oh, yeah, that 90 degree angle is difficult part, but it's slowly getting better.
00:00:37Okay, good, good.
00:00:41Now, let's do the side swing, okay?
00:00:47Yeah, martial arts.
00:01:01Yeah, good enough.
00:01:03Okay, five minutes break please, thank you.
00:01:17Okay.
00:01:47Okay.
00:02:17Okay.
00:02:47Okay.
00:03:17Okay.
00:03:47Okay.
00:04:17Okay.
00:04:47Okay.
00:05:17Okay.
00:05:37Welcome to Humanology.
00:05:43Let me give you some terms.
00:06:03I watched some YouTube documentaries.
00:06:05One of them about Isaac Newton.
00:06:07Yeah, no, no.
00:06:09YouTube biography channel.
00:06:11I learned that they actually have television, cable TV channel too.
00:06:15Okay.
00:06:17And Isaac Newton, interesting biography.
00:06:22Yeah, it's on YouTube.
00:06:24And, I mean, okay.
00:06:29Welcome to Albert Einstein.
00:06:31Dumb, okay?
00:06:33Worshipers of Albert Einstein, dumber.
00:06:35So it's dumb and dumberers.
00:06:37Dumb and dumberers, okay?
00:06:39It's group hallucination, special general relativity, okay?
00:06:44There are four theories, and let me get some drinks.
00:06:49I disprove them, okay?
00:07:00I disprove Albert Einstein twice, okay?
00:07:07Then what's the alternative theory?
00:07:09It's just Newtonian physics.
00:07:11That's it, okay?
00:07:13There's nothing after that, really.
00:07:17Okay?
00:07:20They'll learn later.
00:07:22We'll give them time.
00:07:23There's no rush.
00:07:25It's group hallucination, and they say, oh, there's some physical evidence supporting Albert Einstein.
00:07:32There is none.
00:07:33It's all lies.
00:07:35Conspiracy, group hallucination, data manipulation.
00:07:39It's like what's called the fallacy of confirmation bias, okay?
00:07:50They're feeding their data, manipulate their data in order to confirm Einstein's false equations, okay?
00:07:58So that's all it is about, okay?
00:08:01It's group hallucination.
00:08:03It's like a mass illusion in science for the past 100 years, okay?
00:08:11Yeah.
00:08:12Special general relativity, okay?
00:08:14Yeah.
00:08:15They'll learn in time, okay?
00:08:18Cheers.
00:08:22Well, yeah, but that's group hallucination in science.
00:08:26Yeah, the ideological pandemic in science, okay?
00:08:29Past 100 years.
00:08:31That happens in politics, too.
00:08:33Yeah.
00:08:35America, half of them supporting Biden can barely walk.
00:08:41It's a comedy, okay?
00:08:43And the other half supporting convicted felon Trump.
00:08:46It's mass illusion.
00:08:48It's group hallucination in politics, okay?
00:08:51Yeah.
00:08:52Same thing happened before World War II, too.
00:08:54Yeah.
00:08:55Germany.
00:08:56Germany.
00:08:57They democratically elected Adolf Hitler, okay?
00:09:02Yeah.
00:09:03That happens, okay?
00:09:06Yeah.
00:09:08Yeah.
00:09:09Yeah.
00:09:10I also watched documentary with Salvatore Dali, yeah, the painter, surrealist.
00:09:23Yeah, he's one of my favorites, okay?
00:09:26Okay, interesting biography, yeah?
00:09:28He got support from his wife, okay?
00:09:32For 50 years, yeah.
00:09:36Yeah.
00:09:40Interesting people.
00:09:42Okay, that's pretty much it.
00:09:46Let's get back to mathematics.
00:09:49Yeah, I eat good food, ramen noodle, and I'm full.
00:09:55It's the digestion, digestion fatigue.
00:10:00Yeah.
00:10:02Sure, mathematics, sure, sure.
00:10:06We do the same thing with number five, okay?
00:10:08Yeah.
00:10:10Let me grab a whiteboard.
00:10:31Okay.
00:10:35Yeah.
00:10:38Yeah.
00:10:49Yeah.
00:10:59Just a little whiteboard.
00:11:28All right.
00:11:38Okay.
00:11:48Yeah, let's erase this.
00:11:55Yeah, boom.
00:11:58Nice catch on.
00:12:02Okay.
00:12:06Okay.
00:12:24Let's find greatest common divisor of five and other numbers.
00:12:43Numbers bigger than five, okay?
00:12:44Yeah.
00:12:53Let's go.
00:12:54But let me take off my long pants, okay?
00:12:57It's 71 Fahrenheit outside.
00:13:02I have short pants on this, okay?
00:13:03So, okay.
00:13:09It's warm.
00:13:18Yeah.
00:13:23Whoa.
00:13:25Cheers.
00:13:32Mm-hmm.
00:13:42Oh.
00:13:55Yeah, there's a coefficient.
00:14:1714.
00:14:3816.
00:14:5410.
00:15:12How interesting.
00:15:15It decreased in absolute value, okay?
00:15:17We have not seen that before.
00:15:20But, I mean, there are other basic coefficients, okay?
00:15:23That may follow some pattern, okay?
00:15:25So, but for now, yeah.
00:15:28Let's move on.
00:15:3211, yeah.
00:15:3310.
00:15:5224.
00:16:04Jumps quite a bit.
00:16:09Okay.
00:16:2826.
00:16:57Okay.
00:17:2626.
00:17:36Okay.
00:17:56Okay.
00:18:24Okay.
00:18:44Thanks.
00:19:1554.
00:19:2954.
00:19:4256.
00:19:47Okay.
00:19:48Those are basic coefficients, okay?
00:19:50So, and it's less obvious than before.
00:19:59Okay, so we need to manipulate this a little bit to find different basic coefficients to observe,
00:20:08to see if there are patterns, okay?
00:20:10Because if you know one basic coefficient pair, then calculating the rest is easy.
00:20:15It's just like algebra, you know?
00:20:17That's just adding the other number again and again and again and again.
00:20:22Okay?
00:20:23All right.
00:20:25Yeah, number does fluctuate, absolute value.
00:20:31But it tends to increase overall.
00:20:37Okay?
00:20:38It's like this wave, but it's going up.
00:20:41Okay?
00:20:42Yeah.
00:20:43All right, let's take five minutes break, okay?
00:20:44Thank you.
00:20:47Yeah.
00:20:48If you want to find formula for it, go for it, okay?
00:20:51Yeah.
00:20:53Okay, nice.
00:20:57We are back in the game.
00:21:01Okay.
00:21:08Five minutes, thank you.
00:21:09Yep.
00:21:31Okay.
00:22:01Okay.
00:22:31Okay.
00:23:01Okay.
00:23:31Okay.
00:24:01Okay.
00:24:32Okay.
00:24:38Now, let's take a break from mathematics, as usual.
00:24:45Let's talk about dilution, okay?
00:24:47So, here, basically, found formula for gravitation, okay?
00:24:56Yeah, the three equations of motion, calculus.
00:25:05Those are the major discoveries of Newton, okay?
00:25:08And so, but back in the days, we are talking about, like, 1700s, okay?
00:25:161600s.
00:25:19So, back then, science was developing, okay?
00:25:26He also did some alchemy, too,
00:25:28and he got some nice inspiration from alchemists, okay?
00:25:32Back then, alchemy was quite mainstream, let's give it science.
00:25:37Superstition, regarded as superstition, pseudoscience these days,
00:25:42but back in the days, they were regarded as science, okay?
00:25:47Alchemy.
00:25:49Okay?
00:25:50Yeah.
00:25:51It was like chemistry of the day, okay?
00:25:53So, Newton did some alchemy, okay?
00:25:57He got some good inspiration,
00:25:59legitimate inspiration from alchemists as well.
00:26:02Okay?
00:26:03Yeah.
00:26:04Now, when he started talking about gravitational force,
00:26:12universal law of gravitation,
00:26:15people were skeptical, mainstream scientists were very skeptical about it.
00:26:19But it sounds like magic.
00:26:24You have two masses, like Sun, Earth,
00:26:28that's so far away,
00:26:30but there's this invisible force,
00:26:33now known as gravitational force.
00:26:36It looks like magic.
00:26:37There's no connecting medium, vacuum, long distance,
00:26:42but still they are exerting invisible force.
00:26:47It sounds like superstition, like magic.
00:26:50Okay?
00:26:51So, he was heavily criticized initially,
00:26:55and he hated it.
00:27:02Okay?
00:27:04When I was in high school in South Korea,
00:27:19I paid a visit to my physics teacher,
00:27:24fantastic gentleman, okay?
00:27:26Great teacher.
00:27:27And went to his office hour and asked him a question.
00:27:33My question was somewhat philosophical, okay?
00:27:36These two bodies of mass, why do they attract each other?
00:27:41Do you know what his answer was?
00:27:46Why don't you take a guess?
00:27:47I'll give you a minute, okay?
00:27:51It was surprising answer.
00:27:53Interesting.
00:27:54Cheers.
00:27:56Hint is, look, Einsteinian time warp, space warp, curvature,
00:28:04that's wrong theory.
00:28:06So, my teacher's answer has nothing to do with that, okay?
00:28:11Einstein's special relativity theory, they're wrong.
00:28:14So, you know it, okay?
00:28:16You all know what you learned there.
00:28:18They're wrong theories, period.
00:28:21They're worthless, okay?
00:28:24Okay?
00:28:25Yeah.
00:28:26Except for inspiration for fiction writer, science fiction writer, sci-fi, okay?
00:28:31Yeah, that's quite useful contribution there.
00:28:33Sure.
00:28:34Sure.
00:28:35But not in science though, okay?
00:28:36Because it's not a science.
00:28:38It's a fiction, science fiction, okay?
00:28:40Special relativity, okay?
00:28:46My teacher's answer was this, okay?
00:28:48He said, only God knows.
00:28:51And I agree.
00:28:54It's arbitrary.
00:28:56I think God just made it that way.
00:28:59I agree with my teacher.
00:29:02Yeah.
00:29:03There's no rhyme or reason why two mass should attract each other.
00:29:08It's very weak force.
00:29:11Okay?
00:29:13It takes humongous planet to feel the effect of gravitational force.
00:29:22It's a very weak force in nature, okay?
00:29:25Electric force or magnetic force, electromagnetic force,
00:29:29is by far astronomically stronger force than gravitation, okay?
00:29:35Yeah.
00:29:38Yeah.
00:29:43Yeah.
00:29:48So why, okay, in magnetism, yeah, you have North Pole and South Pole, okay?
00:29:53Why do they attract each other?
00:29:55Same, two magnets, okay?
00:29:59Same poles, they repel each other.
00:30:03Electricity.
00:30:05Yeah.
00:30:06Positive charge, negative charge, they attract each other.
00:30:09Same charge, they repel each other.
00:30:11Why?
00:30:12There is no why, it's just the way it is.
00:30:15That's how God designed this universe.
00:30:18I think that's the best answer, actually.
00:30:20Okay?
00:30:24In my opinion, okay?
00:30:27It's random, arbitrary.
00:30:30Who knows, maybe in the future, maybe future scientists like you,
00:30:36some of you, may discover something there.
00:30:39Maybe there's some reason for it.
00:30:41Sure, go for it, okay?
00:30:43For me, it's not my job, okay?
00:30:47But you want to explore, go for it.
00:30:51You may find some explanation.
00:30:54Okay?
00:30:56Me, I'm not into the adventure.
00:30:58I'm not interested in exploring that, okay?
00:31:01But Alice not now, okay?
00:31:04Because I got to do this.
00:31:07Okay.
00:31:09Cheers.
00:31:10Yeah.
00:31:17Okay, now, pattern.
00:31:201 minus 1, 2.
00:31:22Then minus 1, 1.
00:31:24Minus 2, 2.
00:31:26Minus 1, 1.
00:31:28Minus 2, 2.
00:31:29Minus 1, 1.
00:31:30Minus 2, 2.
00:31:31Minus 1, 1.
00:31:32Minus 2, 2.
00:31:33So there's deviation from pattern, okay?
00:31:38And we will try to fix it
00:31:42by finding different Bezier coefficient pairs,
00:31:47which is easy, okay?
00:31:49Yeah.
00:31:55So that's left coefficient.
00:31:56Right coefficient, minus 1, 3.
00:32:00Minus 3, 2.
00:32:01Minus 2, 5.
00:32:02Minus 5, 3.
00:32:03Minus 3, 7.
00:32:04Minus 7, 4.
00:32:05Minus 4, 9.
00:32:07Minus 9, 5.
00:32:10Minus 5, 11.
00:32:12Minus 11.
00:32:13Okay, okay.
00:32:24Up, down.
00:32:25Up, down.
00:32:26Up, down.
00:32:27Up, down.
00:32:28Up.
00:32:29Okay, that's our pattern there.
00:32:31Okay.
00:32:37Phew.
00:32:43Mm-hmm.
00:32:56I'm kind of being overheated,
00:32:58so let's take five minutes break, okay?
00:33:00And I'll change to how I'm teaching, okay?
00:33:02So it is past summer day in Alaska.
00:33:06Okay, five minutes.
00:33:07Thank you.
00:33:08Yep.
00:33:14There we go.
00:33:16Mm-hmm.

00:36:14Yep.
00:36:15Yep.
00:36:16Yep.
00:36:17Yep.
00:36:18Yep.
00:36:19Yep.
00:36:20Yep.
00:36:21Yep.
00:36:22Yep.
00:36:23Yep.
00:36:24Yep.
00:36:25Yep.
00:36:26Yep.
00:36:27Yep.
00:36:28Yep.
00:36:29Yep.
00:36:30Yep.
00:36:31Yep.
00:36:32Yep.
00:36:33Yep.
00:36:34Yep.
00:36:35Yep.
00:36:36Yep.
00:36:37Yep.
00:36:38Yep.
00:36:39Yep.
00:36:40Yep.
00:36:41Okay, let's talk about Newton some more.
00:36:42He never got married.
00:36:43He never had children.
00:36:44And his colleagues said he had absolutely no interest in women.
00:36:52So, some people may think that, maybe he was LGBT.
00:36:57Some people may think that, but I don't think so.
00:37:02Newton was a very big, deeply religious man.
00:37:08He was a protestant, Christianity.
00:37:12He firmly believed in God, Creator.
00:37:16As he studied astronomy, physics, the cosmos, the orderliness.
00:37:23So he believed in the Creator.
00:37:25He was a deeply religious man.
00:37:34He had some temper issues.
00:37:37He did not take criticism very well.
00:37:40His contemporaries, like Robert Hooke, the Hooke's Law, in like, Ethical KX, the spring.
00:37:46Yeah, the Hooke's Constant K.
00:37:49He did not get along.
00:37:52Also, Leibniz, another co-inventor of calculus, okay, they did not get along either, okay.
00:38:01So he has a temper issue, okay, Newton, okay, so.
00:38:09Yeah.
00:38:12Nobody's perfect, okay, so.
00:38:14But he got, later on, he got famous, Newton, and he got some governmental job, too, and
00:38:19he did very well there, as well.
00:38:22The Secretary of Mint, like coinage, okay, so, he did very well there, okay.
00:38:29But I read some history about it, like, faking coin back then, we're talking about like 1700s
00:38:36England, okay, it was punishable by death, yeah, the counterfeiting, the coin, messing
00:38:43with it, because it was made with gold and silver, precious metal, okay, so, it was counted
00:38:48as treason.
00:38:51People would get public execution, yeah, back in the days, people used to be very cruel,
00:39:01it was horrible.
00:39:06For death penalty for guys, public execution, disembowelment, and dismemberment, like quartering,
00:39:16basically, cutting four limbs, disembowel, in public execution in United Kingdom.
00:39:26We're talking about 1800s.
00:39:29And for females, yeah, burning alive, public execution, and it was both male and female,
00:39:41like, death penalty, public execution, it was huge entertainment venue in Europe, we're
00:39:49talking about like 1600s, 1700s, okay, it was horrible back then, even in Europe, okay,
00:39:58yeah.
00:39:59I mean, even today, some African countries, I'm not sure even today, but even quite recently,
00:40:09stoning, that's public execution by the people, they would sell, like, colored, color-painted
00:40:18stone, that's so uncivil, okay?
00:40:27I saw pictures, maybe not anymore, some African countries, okay, it's an entertainment venue,
00:40:37maybe 10 years ago, but it was color photo, okay, so maybe 30 years ago, 40 years ago,
00:40:45I don't know, but it was color photo, okay, so not too long ago, okay?
00:40:52Even today, then I don't know, okay?
00:40:55But they'll get better, okay?
00:41:04People evolve, okay, yeah, okay.
00:41:17One, three, two, five, three, seven, then four, nine, five, eleven, okay, four and nine,
00:41:27yeah, they are not prime numbers, okay.
00:41:34Mm-hmm.
00:41:49Uh.
00:42:04Okay, one minus one, then two, okay.
00:42:16Wait a minute, I made a mistake here.
00:42:31This is minus two.
00:42:41Good.
00:42:43One minus two, two, minus one, one, minus two, two, minus one, one, minus two, two,
00:42:57minus two, two, minus one, one, minus two, two, minus one, one, minus two, two, good.
00:43:05Yeah, there's definitely a pattern there.
00:43:09The left number, okay, but the right number, mm, that's trickier.
00:43:15Yeah.
00:43:27Because it goes up, down, absolute value, okay, right coefficient, go up, down, up,
00:43:41down, up, down, up, down, up, okay?
00:43:46Well, it's some kind of pattern, okay.
00:44:00Well, probably it's not a good idea to make the variation to the coefficient pairs,
00:44:09because we do not want to disturb the pattern on the right side.
00:44:17Because to make variation, we have to add or subtract in both coefficient sides, okay,
00:44:25so yeah, we don't want that, okay, yeah, we don't want to disturb the good pattern on the left side.
00:44:35Okay, the right-hand side, we have to work it out, okay, yeah.
00:44:55Up, down, up, down, okay, let's think about this sequence, okay?
00:45:05Absolute value, okay, yeah, yeah, minus, plus, minus, plus, minus, plus, yeah, there's a pattern there, so.
00:45:22Okay, now let's find the difference, okay?
00:45:27Like in physics experiment, right, gravitation, yeah,
00:45:34the 9.8 meter per second, it's quadratic equation, right, so yeah, to find the acceleration,
00:45:45yeah, you subtract the velocity, basically, right, yeah, then it becomes regular pattern, okay.
00:45:55We do similar thing, okay, yeah, I remember from my high school physics class, okay.
00:46:01Okay, yeah, it's subject to difference, okay, see, there's some pattern between the differences, okay, yeah.
00:46:09Different between two adjacent numbers here, okay, five minutes, okay, thank you.
00:46:16You want to do it? Go for it.
00:46:24Nice, okay.
00:46:30Thank you.
00:47:00Thank you.
00:47:30Thank you.
00:48:00Thank you.
00:48:30Thank you.
00:49:00Thank you.
00:49:30Okay.
00:49:42Okay.
00:49:44Okay.
00:49:48Let's take a break from mathematics.
00:49:50Yeah, calculator difference, go for it if you want to, okay.
00:49:54Let's take a break from mathematics, okay, so when I was in Korea two weeks ago, I had a wonderful conversation with my parents, okay, and uncles and my parents' friends, siblings, of course, okay, cousins, oh yeah, yeah, it was nice, yeah.
00:50:12And I asked my father, he's retired now, he's in his 70s, okay, but when he was an economics professor in front of undergraduate college students, I asked my father, he's a handsome guy, okay, so charismatic and great sense of humor, okay, very intelligent and athletic, yeah.
00:50:38And I asked him, like, hey, did you ever have this experience where your college, female college students, who are in their, like, late teens, early 20s, having crush on you?
00:50:52He said no.
00:50:54I'm not sure if he's telling the truth, okay, I don't know, because, yeah, my mother was there too, okay, when we were having this conversation, okay, so I don't know.
00:51:04How about me?
00:51:10In social media?
00:51:12What I would say is this, okay, yeah, I'm handsome, I'm 46, intelligent, great sense of humor, great writer, and I look very young, I think young, so yeah, I'm very popular among young people, both males and females, okay.
00:51:40That's all I can say, okay, and I regard them as my children or students, okay, yeah.
00:51:54Good-looking people, yeah, I'm very proud of their parents and their teachers, they educated them so well, okay.
00:52:04Good-looking, yeah, yeah.
00:52:08Both genders, okay, yeah, very proud, very proud.
00:52:12Okay, that's all I can say, okay?
00:52:18Now, let's get back to this.
00:52:20What differences, okay?
00:52:34Now, is there some pattern here?
00:52:52Not yet.
00:52:54Let's do it again, yeah, differences, okay?
00:53:16Do you see any pattern here?
00:53:18Yeah, 3, 4, 5, 6, 7, 8, 9, 10.
00:53:26Well, let's do one more time.
00:53:48Is there a pattern here? Yeah, yeah.
00:53:507, 9, 11, 13, 15, 17, 19, yeah, like, absolutely very wise.
00:53:58Yeah, plus 2, plus 2, here, plus 1, plus 1.
00:54:01Let's do it again.
00:54:06It's like first order, second order, third order polynomial kind of concept, okay?
00:54:13So, yeah, it's like calculus differentiation, okay?
00:54:17Okay?
00:54:36Yeah, absolute value, yeah, plus 4, plus 4, plus 4, plus 4.
00:55:03Let's do one more, or two more.
00:55:25Plus 8, I guess, okay?
00:55:52Okay, one more time.
00:55:59Number gets big.
00:56:0996.
00:56:13Okay, so add 16, okay, okay.
00:56:37So add 16, add 16, add 16.
00:56:43One more time, okay?
00:56:46Yeah, bear with me, please.
00:56:53I guess add 32, okay, yeah.
00:57:20Yeah, add 32, add 32, okay, yeah.
00:57:25Good, good, we found pattern.
00:57:29Fantastic.
00:57:35Very good.
00:57:37Cheers.
00:57:43Yeah, I remember when I took exam to go to like a special purpose high school,
00:57:48like science high school for elites, okay?
00:57:51Yeah, I remember there was some problem like this, okay?
00:57:54Yeah, like calculating the difference of a sequence, okay?
00:57:57Kind of figuring out, you know, the order of polynomial.
00:58:01Yeah, I remember this, okay?
00:58:06Excellent.
00:58:09Yeah, it's beautiful.
00:58:12We found a pattern.
00:58:14Cheers.
00:58:16Yeah.
00:58:29Then the degree of polynomial for this formula for the second Bezier coefficient
00:58:37looks like it may be like a third degree, like cubic polynomial, like x squared plus x,
00:58:47I mean x cubed plus x squared plus x, something like that, that kind of stuff, okay?
00:58:52Sounds like it could be, it would be a cubic polynomial, okay?
00:58:56The formula for this.
00:58:58Okay.
00:59:01But we got it.
00:59:05We got the pattern.
00:59:07Finding formula for this from here, it will not be that difficult.
00:59:13Finding the pattern, that's the difficult part, okay?
00:59:15So we overcame the difficult hurdle here.
00:59:20The rest will be easier.
00:59:24Yeah.
00:59:25Cheers.
00:59:28We are good at it, okay?
00:59:29Yeah, we are very good at mathematics, okay?
00:59:31Cheers.
00:59:36Yeah.
00:59:39Let's take five minutes break.
00:59:40I need some vocal rest.
00:59:41Yeah.
00:59:42Let's relax.
00:59:44Yeah.
00:59:47Time check.
00:59:49It's been one hour.
00:59:50Time flies, huh?
00:59:52Yeah.
00:59:54Okay, five minutes.
00:59:55Thank you.
00:59:57This is nice.
00:59:58I'm glad we are doing this.
01:00:00Oh, yeah.
01:00:02Very cool.
01:00:10There we go.
01:00:11Fantastic.
01:00:13Bye-bye.
01:00:43Bye-bye.
01:00:44Bye-bye.
01:00:45Bye-bye.
01:00:46Bye-bye.
01:01:13Bye-bye.
01:01:14Bye-bye.
01:01:44Bye-bye.
01:01:45Bye-bye.
01:01:46Bye-bye.
01:02:14Now, let's talk about Newton again.
01:02:25Okay?
01:02:28Yeah, let's relax.
01:02:35Let's enjoy.
01:02:38Let's have some fun.
01:02:42Hooke, Robert Hooke, Hooke's law,
01:02:46yeah, the spring Constance,
01:02:47Hooke's Constance,
01:02:51F equal to KX, okay,
01:02:52so Robert Hooke was way more famous than Isaac Newton.
01:03:00Earlier in Newton's career, okay,
01:03:03and so Robert Hooke was head of the Royal Society
01:03:10in United Kingdom, okay,
01:03:11that's like, it's an association of top scientists
01:03:18in United Kingdom, okay, Royal Society.
01:03:21Robert Hooke was head of that organization, okay,
01:03:25it's like Harvard, Cambridge,
01:03:28yeah, the top scientists in United Kingdom, okay, yeah.
01:03:35Robert Hooke, he recognized Isaac Newton, okay,
01:03:42he recognized genius in Isaac Newton,
01:03:45he actually helped him in many ways,
01:03:51but as a competing scientist, okay,
01:03:54he did criticize, and they had a debate, public debate,
01:03:59and Isaac Newton left that debate with Robert Hooke, okay,
01:04:04he just walked out of the room, why?
01:04:07He was so offended by Robert Hooke's criticism,
01:04:12but he couldn't take it anymore, so he just left.
01:04:14He's like, I can't talk about this.
01:04:21It's kind of like me, like,
01:04:23leaving messed-up stage in a con, okay,
01:04:27so many people are mean to me there,
01:04:29I know, there are nice people there, I know,
01:04:33because I've seen some good people there,
01:04:37messed-up stage in a con, okay,
01:04:39but some of those are so mean to me,
01:04:41many of them, too many of them,
01:04:44so I left there, I don't have time for this, okay, so.
01:04:53Well, I'm kind of flattering myself
01:04:55by comparing me to Isaac Newton,
01:04:59and also, as a filmmaker,
01:05:01comparing my movie with David Lynch's,
01:05:04like, therapy for mental illness,
01:05:07I compare that with Hollywood director David Lynch's,
01:05:11like, Mulholland Drive, okay,
01:05:12yeah, I kind of flatter myself, okay, yeah,
01:05:15but I'm a huge fan of Isaac Newton
01:05:18and director David Lynch, okay, yeah, yeah.
01:05:23I'm a huge fan of you, too, okay, yeah, of course, okay,
01:05:28yeah, so be ambitious, okay, yeah,
01:05:31find your passion and go get it,
01:05:34and be famous, okay, yeah.
01:05:37Okay, yeah, you'll get it, I have no doubt, okay, yeah,
01:05:40cheers, yeah.
01:05:47Okay, so, formula for this.
01:05:58Okay.
01:05:59Okay.
01:06:05Well,
01:06:10well, I mean, sine, plus sine minus sine,
01:06:14plus sine minus, it alternates, okay, so that's easy, okay.
01:06:20So we'll do step-by-step on this, okay, yeah.
01:06:24Yeah, it's a sequence of positive integers, okay,
01:06:28so, like, this is a1, a2, sequence, okay,
01:06:39dot, dot, dot, aN is equal to some function of N, okay,
01:06:47yeah, that's the function formula that, yeah,
01:06:53that's what we're looking for, okay.
01:07:01Yeah, it's like algebra, it would be a polynomial,
01:07:05of like a star degree, I guess, okay,
01:07:11cubic equation, okay.
01:07:24So we frame the question, that's good, good step, okay.
01:07:41Tricky part?
01:07:42Yeah, alternating sign, but that's easy,
01:07:45because it's fixed pattern, minus plus minus plus, okay.
01:07:54Yeah.
01:08:05All right, now, let's do bN, okay.
01:08:13You have b1, b2, b3, okay, so you have bN
01:08:18is equal to what, let's say, g of N, okay.
01:08:24Now, cN is equal to hN, okay, function.
01:08:35We know what this is, okay,
01:08:47yeah, okay, yeah, oh yeah, N starting from one, okay,
01:08:52so now N plus two, right, so it start from three, okay,
01:08:57yeah, N starting from one, okay, so now N plus two, right,
01:09:18so it start from three, okay, yeah,
01:09:22one plus two is three, okay, so N,
01:09:24on and on and on, okay, so an alternating sign,
01:09:27yeah, minus one to the N, okay, so, okay.
01:09:32Okay, yeah, this is easy, easy problem to solve.
01:09:38Difficult part?
01:09:39Yeah, finding the pattern, that's the difficult part, okay.
01:09:43Yeah, we're kind of inspired by Isaac Newton, sure.
01:09:48Acceleration, right, yeah,
01:09:52classical mechanics in physics.
01:09:55You have distance, like displacement, okay,
01:09:59and then velocity, higher level, acceleration, yeah.
01:10:07Yeah, you can go to third degree too, sure,
01:10:11and force, okay, to generalize, okay, cheers.
01:10:17Cheers.
01:10:24Let's do the rest tomorrow, okay, why?
01:10:29I'm kind of getting drunk, okay, so,
01:10:32and tomorrow at work, I need to get there
01:10:35one hour earlier than usual, okay,
01:10:40so I need to have a good night's sleep, okay.
01:10:45Let's go to Instagram live, okay,
01:10:47and then we'll do this tomorrow, the rest, should be easy,
01:10:55okay, yeah, because I don't want to overdo this.
01:10:59I want to enjoy doing this.
01:11:01If I overdo this, then I will be bored,
01:11:06and I don't want that, okay, so, yeah.
01:11:15Mm-hmm.
01:11:25Yeah.
01:11:28I sleep on this, okay, yeah,
01:11:30but this is not a difficult problem at all, okay,
01:11:35but I might think about it when I'm in my bed.
01:11:40Not mad, no, I'm not taking any medicine, okay,
01:11:42when I'm in my bed.
01:11:45When I'm in my bedroom, but if I'm not sleepy,
01:11:47you know, I may think about this,
01:11:50because I have pencil and paper in my bedroom,
01:11:52on my bed, okay, yeah.
01:11:55Cheers.
01:11:57How nice.
01:12:04Mm-hmm.
01:12:16Mm-hmm.
01:12:18You know what, I kind of want to do this some more, okay,
01:12:21so let's take five minutes break, okay?
01:12:23We can kind of reverse engineer this, okay,
01:12:26and yeah, forget about the signs.
01:12:29We'll just make it all positive, okay, so,
01:12:32because, yeah, yeah, let's take five minutes break,
01:12:36and let's just do a little bit more, okay?
01:12:39We have room here, okay, so.
01:12:43Yeah.
01:12:45Mm-hmm.
01:12:50Enter again.
01:12:58Okay, here we go, yeah, five minutes, thank you, yep.
01:13:03Oof.
01:13:11All right.
01:13:15Mm-hmm.
01:13:18Mm-hmm.
01:13:21Mm-hmm.
01:13:24Mm-hmm.
01:13:27Mm-hmm.
01:13:30Mm-hmm.
01:13:33Mm-hmm.
01:13:36Mm-hmm.
01:13:40Mm-hmm.
01:13:43Mm-hmm.
01:13:45Mm-hmm.
01:13:48Mm-hmm.
01:13:53Okay.
01:13:57Mm-hmm.
01:14:01Mm-hmm.
01:14:04Mm-hmm.
01:14:07Mm-hmm.
01:14:11Okay.
01:14:12you
01:14:42you
01:15:12you
01:15:27okay so but let's take a break from mathematics okay yeah in Alaska
01:15:33honeybees they are not native to Alaska it's too cold okay but beekeepers
01:15:38honeybee farmers yeah there are many of my friends do that as a hobby okay so
01:15:44yeah they purchase out-of-state honeybee queen, queen bee okay so yeah so about
01:15:53several months ago okay maybe two months ago yeah nice beautiful honeybee flew and
01:16:00sat on as I was going to work in the morning okay sat on the nook the
01:16:07crevice area between my car pooled and windshield okay and what a cute little
01:16:17honeybee and insect okay the honeybee yeah there were female honeybees okay so

01:17:02candidacy okay so oh honkily yeah your candidacy is a joke why do you don't
01:17:09drop out and I'm like look as a Trump convicted felon and Joe Biden can barely
01:17:17walk auto-generate and they're running for US president okay that's more
01:17:22serious joke joke than me running for US president okay so I'm smarter than
01:17:27both of them so yeah and I may look like a joke but I'm more serious than they
01:17:37are I'm more serious candidate because I'm smarter than they are for me it's
01:17:40the right thing to do run for US president okay whether I get elected or
01:17:44not okay yeah that was my answer
01:17:49hmm but yeah the debate will be interesting to watch yeah two days from
01:17:56now sure I look forward to it
01:18:00okay now let's reverse engineer this okay so
01:18:07let's make it easier okay so
01:18:12you yeah it's all floor second floor fourth floor okay
01:18:18we'll reverse it okay so
01:18:25yeah on the ground okay yeah
01:18:29you
01:18:33one plus one two two plus two oh okay we reverse engineering this now we are
01:18:41adding up if in terms of subtracting them okay so
01:18:59you
01:19:03okay
01:19:06we'll double check the calculation
01:19:10calculations
01:19:14okay now third floor second floor fourth floor okay
01:19:29you
01:19:48okay good
01:19:52so
01:19:55you

01:20:17you
01:20:22it's been a while since I did this okay it's been a while
01:20:33it's kind of a geometry series or arithmetic series I don't know
01:20:41you
01:20:43if you have to do some n squared okay here you have linear this will be
01:20:49quadratic and this will be cubic okay
01:21:10you
01:21:20and here
01:21:28okay just add one one one one okay okay
01:21:34you
01:21:39okay so just dn
01:21:45I n
01:21:48yeah it's like our integration of the previous owner

01:22:57years ago
01:23:04you
01:23:12yeah it's like subtraction down downward audition like upward it's like
01:23:18differentiation integration okay so
01:23:22you
01:23:24you
01:23:43yes it comes
01:23:46you
01:23:52it's been a while

01:31:13this sake I need to stop because my neck is hurting okay
01:31:22we'll pick this up tomorrow okay Oh I know when to stop okay so yeah
01:31:32let's do Instagram live and I change the angle of my chair so that I don't
01:31:38my neck anymore yeah
01:31:46and I keep track of time of course
01:31:51you
01:32:04so I think I told you this story maybe yesterday or the day before I don't know
01:32:10like I write novels in social media okay short stories and about year or so ago
01:32:22one of our guests in social media like Instagram live I think it was maybe it
01:32:27was zoom open zoom days two years ago I don't know okay so yeah this gentleman
01:32:34read what I wrote in social media and I felt like I was being stripped naked
01:32:40because it was a little bit PG-13 ish controversial I wrote those novels when
01:32:48I'm in my bedroom like before I fall asleep or after I wake up I'm still in my
01:32:59bed and if it's like before I fall asleep yeah then I'm like totally drunk
01:33:08if it's after I wake up in the morning it's like I'm having a hangover okay
01:33:15yeah yeah so when I write short stories in social media there I collect and
01:33:27publish once a month in Amazon Kindle okay and there are not always but I'll
01:33:35say 90% of time yeah it's when I'm intoxicated
01:33:41kinda okay sometimes I write when I'm sober sometimes
01:33:48you
01:33:54but yeah arts the fictions okay yeah when I was a politician well I still am a
01:34:04politician but when I was actually doing campaigning I used to write to like
01:34:12local newspapers okay there are no fictions they're about problem-solving
01:34:16okay here's problem and here's solution okay but there are so many problems in
01:34:23the world and I solved all of them solutions for every single one of them
01:34:28okay and then I ran out of things to write about okay those are non-fiction
01:34:34okay but in fiction space there's no it's not finite set of things to write
01:34:42about because it's imaginary space I can write about whatever in fiction
01:34:50space in non-fiction space yeah the number of topics are limited
01:34:59how many political problems do we have in the world it's finite set for now
01:35:05okay you know given time
01:35:10I solved it all okay okay now what else do I write about okay let's move up to
01:35:16fiction space as opposed to non-fiction space or politics
01:35:22in fiction space there's no limit because it's imaginary land
01:35:32there are infinite topics to write about in fiction space yeah that's why I migrated
01:35:39to fiction space okay I used to be a non-fiction writer okay yeah solution to
01:35:46political problems in the world okay
01:35:51but they all solved I wrote about it it got all published
01:35:57okay well mostly in social science research network okay so yeah
01:36:06yeah
01:36:11now how much time do we have in telemotion? 10 minutes I guess
01:36:19you
01:36:21okay how about this okay let's stop it right here okay and we let this zoom
01:36:29software to like digitize it okay because when it digitizes I cannot do
01:36:36another show okay so I have to wait otherwise it crashes okay and lose my
01:36:41footage okay it happened once before okay so okay so yeah let's stop here and
01:36:46then after like five minutes after zoom software digitizes it, then we restart with
01:36:54Instagram live okay yeah sounds like a plan okay yeah we'll see tomorrow well
01:36:59I'll see you in 10 minutes or five minutes okay thank you yeah very cool
01:37:03god bless you be ambitious okay yeah love my charge focus on education okay
01:37:10thank you be the leaders thank you yep
