Latest / Stuff You Should Know / SYSK Selects: How Zero Works
Transcript
- 0:00Speaker 1: Hi there, how there, It's me Josh, your friend with
- 0:04Speaker 1: this week's edition of s Y s K Selects. And
- 0:08Speaker 1: for this week I've selected How Zero Works, a surprisingly
- 0:12Speaker 1: riveting episode about Zero. You know, Zero, made famous by
- 0:16Speaker 1: the phrase you better lose that zero and get yourself
- 0:20Speaker 1: a hero. Well, it turns out Zero is pretty great
- 0:23Speaker 1: in its own right. Just listen to this episode. Okay, enjoy.
- 0:30Speaker 1: Welcome to Stuff you Should Know, a production of My
- 0:33Speaker 1: Heart Radios How Stuff Works. Hey, and welcome to the podcast.
- 0:41Speaker 1: I'm Josh Clark. There's Charles W. Chub Bryant, and this
- 0:45Speaker 1: is a rare, unusual mathematical uh episode of the Stuff
- 0:50Speaker 1: you Should Know. Yes, And I'm just gonna step out
- 0:52Speaker 1: of the room and I'll be back in what minutes.
- 0:55Speaker 1: You to do this? This is not going to be
- 0:57Speaker 1: another Yo yo episode. Oh I just hate math. This
- 1:01Speaker 1: was this was This is not math heavy at all.
- 1:04Speaker 1: It's about the history of Zero. It's about the weirdness
- 1:07Speaker 1: of Zero, my hero Zero. Exactly until you came a
- 1:12Speaker 1: people counted on their fingers and toes. I posted that
- 1:15Speaker 1: to down Facebook. I don't know what that is. The
- 1:17Speaker 1: Schoolhouse rock, I don't know he ro Zero. I don't
- 1:21Speaker 1: remember that one until you came along. Keep going it
- 1:23Speaker 1: on her fingers and toes. It's basically you would appreciate
- 1:26Speaker 1: it because it sings what you wrote. Oh, that's great
- 1:31Speaker 1: in a much more basic way. But basically trying to
- 1:34Speaker 1: teach kids how amazing zero is, and don't discount it
- 1:37Speaker 1: as just it's a number. It's not the absence of something. Well,
- 1:42Speaker 1: there's a lot, there's a bunch to it. It's many,
- 1:44Speaker 1: many things. It's a multifaceted uh number, not the multifaceted entity. Well,
- 1:53Speaker 1: nol is German for zero. Did you know that bub
- 1:57Speaker 1: kiss is I believe Spanish for zero zilch silch is cajun.
- 2:03Speaker 1: I did actually get a little etymology research. Originally sanscrit
- 2:09Speaker 1: was sonya, which meant empty. Then later Arabriic was sepia
- 2:14Speaker 1: or nothing, then Italian was sapio, and then finally French
- 2:18Speaker 1: gave us zero, right, and it wasn't you know we
- 2:22Speaker 1: represent zero as something that looks confusingly like an oh
- 2:25Speaker 1: yeah right. That was the Europeans who did that. Prior
- 2:29Speaker 1: to that, the Arabs and I believe the Indians too,
- 2:33Speaker 1: um represented zero with a heavy dot. You know where
- 2:38Speaker 1: that might have come from Robert Kaplan's book The Nothing
- 2:43Speaker 1: That Is a Natural History of Zero. He speculates that
- 2:46Speaker 1: the shape comes from the round depression left in the
- 2:49Speaker 1: sand a sand counting board once you remove a stone
- 2:53Speaker 1: from it, sence would be a round thing, That's what
- 2:58Speaker 1: he he thinks, he speculates. But that wouldn't have haven't
- 3:01Speaker 1: have been the Europeans. It was the Europeans that came
- 3:04Speaker 1: up with that. Well no, but you said, uh like
- 3:07Speaker 1: a heavy dot. Yeah, heavy do could be the depression
- 3:10Speaker 1: where a stone was insane. That's a good one. Who
- 3:14Speaker 1: was that, Robert Kaplan? Thanks? Mr Kaplan. Um, well, I
- 3:20Speaker 1: guess I feel like we've kind of done a pretty
- 3:22Speaker 1: good set up here, Chuck. We've talked about how zero
- 3:26Speaker 1: is multifaceted, um, and you we talked about the Arabs
- 3:30Speaker 1: and the Indians, right yeah, um, And we have to
- 3:34Speaker 1: go back even further. Two first find when Zero made
- 3:40Speaker 1: itself known? Should we get the way back machine? Let's
- 3:44Speaker 1: I think, let's blow the dust off of this thing. Sorry, wow,
- 3:49Speaker 1: that was right at you. I think this thing still works.
- 3:52Speaker 1: Let's find out you're ready? Yeah, hey, look at their
- 3:56Speaker 1: wow lit up like a flex capacitor. Is nice. Um,
- 4:02Speaker 1: we're back in ancient Sumer and these baked clay tablets
- 4:06Speaker 1: haven't even been baked yet. They're still wet. Look, wow
- 4:11Speaker 1: was here? Um so Chuck. If you'll look at this
- 4:16Speaker 1: clay tablet, do you see these two U diagonal lines,
- 4:21Speaker 1: there's little wedges. Yeah, those, my friend, represent nothing really,
- 4:27Speaker 1: And the reason they're there is because round about this
- 4:30Speaker 1: time somebody figured out they ran into a problem and
- 4:34Speaker 1: when they were making some sort of tax record or
- 4:37Speaker 1: grain inventory that um, you know, showing that basically writing
- 4:42Speaker 1: out three thousand lines for the three thousand heads of
- 4:46Speaker 1: cattle doesn't make any sense. But let's say you have, um,
- 4:50Speaker 1: three hundred, you have three thousand heads of cattle, and
- 4:53Speaker 1: all you have are the ways to represent three hundred
- 4:56Speaker 1: heads of cattle. There's a big difference, right, there's an
- 5:00Speaker 1: extra digit in there, and that those two diagonal lines
- 5:04Speaker 1: were used to represent one of those digits when there
- 5:07Speaker 1: was not any digits there. But there's something to the
- 5:09Speaker 1: left of it and something to the right of it,
- 5:11Speaker 1: that's right. And Caplan also said that before that even
- 5:15Speaker 1: they just would leave a blank space sometimes before they
- 5:18Speaker 1: even came up with the little wedges, right, So what
- 5:22Speaker 1: what this is all based on is basically our numerical system,
- 5:27Speaker 1: where if you look at a string of numbers right,
- 5:30Speaker 1: starting from the right, you have the ones column, the
- 5:34Speaker 1: tens column, the hundreds, the thousands, the ten thousands, the
- 5:39Speaker 1: hundred thousands, and so on. You want me to keep
- 5:41Speaker 1: going ad infinitum um. And in each of these columns
- 5:45Speaker 1: there may or may not be numbers present. So when
- 5:48Speaker 1: there are numbers present, we have our friends zero to
- 5:51Speaker 1: serve as what's considered a place holder. Yeah. Makes I
- 5:54Speaker 1: mean it's very easy to just say, well, the now,
- 6:00Speaker 1: but way back then before there was a zero that
- 6:04Speaker 1: you know, we take it very much for granted. Yeah,
- 6:06Speaker 1: this is huge. That's changed everything, changed everything, um, all
- 6:09Speaker 1: of a sudden now because I mean we said there's
- 6:11Speaker 1: a big difference between three thousand head of cattle and
- 6:13Speaker 1: three head of cattle, and by putting a zero there
- 6:17Speaker 1: right saying this this column is represented, there's just not
- 6:21Speaker 1: any in here. You're not going to find the two
- 6:23Speaker 1: cattle that should be in this right, that changed everything.
- 6:27Speaker 1: It changed everything. I mean there was frustrating before that, Yeah,
- 6:30Speaker 1: like if only there was something to put there. Yeah,
- 6:34Speaker 1: And I guess when they like, just trust me, I
- 6:36Speaker 1: have two thousand cattle. And I guess when they left
- 6:38Speaker 1: the blank space that got confusing because they could have
- 6:41Speaker 1: thought it was an error. So they figured we have
- 6:43Speaker 1: to put something there so they know it's not just
- 6:46Speaker 1: an oversight, right exactly. And that's the diagonal lines. Well
- 6:51Speaker 1: in this, uh, I think before it even became that standardized,
- 6:55Speaker 1: it was they used different things. Because they found a
- 6:58Speaker 1: tablet from seven BC and a dude to use three
- 7:01Speaker 1: little hooks to represent zero. Well that would have been
- 7:04Speaker 1: after that, because the Sumerians were doing this like five
- 7:07Speaker 1: thousand years ago. Well, it's probably hard to get the
- 7:09Speaker 1: word around, right, you know, three hooks? What is this crowd? Exactly? Um.
- 7:15Speaker 1: So the Sumerians are the first documented to to come
- 7:19Speaker 1: up or stumble upon zero as a placeholder, and then
- 7:23Speaker 1: it was um codified with the invention of the abbacus,
- 7:26Speaker 1: which uses you know, our numerical column system, right we
- 7:30Speaker 1: used today, um, which was invented by the Babylonians about
- 7:33Speaker 1: three hundred BC. Wow, right, smart folks back then, So
- 7:38Speaker 1: we have zero as a placeholder. We have this understanding
- 7:41Speaker 1: now that there's there's something out there, like we can
- 7:44Speaker 1: represent nothingness, but It wasn't until um, the fifth century
- 7:49Speaker 1: a d in India where zero first comes about as
- 7:53Speaker 1: a concept as a number, which is equally groundbreaking. Yeah. Well,
- 7:57Speaker 1: this nothingness, we should point out, was not something that
- 8:00Speaker 1: people were comfortable with back then. True, oddly now it
- 8:04Speaker 1: seems odd, but to have something representing nothing made people
- 8:08Speaker 1: very uncomfortable. It was associated with chaos and the great
- 8:12Speaker 1: void and even the sign of the devil. Yes, it was. Well.
- 8:16Speaker 1: I mean that if you look at the Christian theology, um,
- 8:21Speaker 1: the void, which is represented by zero or nothingness, was
- 8:25Speaker 1: the state of the universe before the creation of man. Humans.
- 8:30Speaker 1: Uh seeks feel the same way too, although I don't
- 8:32Speaker 1: know how they felt about zero, but that was there there.
- 8:35Speaker 1: That's their conception as well. There was nothing, there's void, um.
- 8:39Speaker 1: And then also void fits well with chaos, which is
- 8:43Speaker 1: the Christian conception of hell, right, like no one's in charge, right.
- 8:48Speaker 1: So yeah, it was avoided. I don't know. I went
- 8:50Speaker 1: back and look, Chuck after I wrote this article, Um,
- 8:53Speaker 1: when we were studying today, I went back and looked,
- 8:55Speaker 1: and I didn't find a lot of support for that,
- 8:58Speaker 1: didn't I did see that like the during the Dark Ages,
- 9:02Speaker 1: monks kind of were Probably they feared zero. Well Kaplan
- 9:06Speaker 1: mentioned it in his book, so, but I mean it
- 9:08Speaker 1: was out there, but there's no well these people did this.
- 9:11Speaker 1: They killed this guy for saying the word zero. There
- 9:13Speaker 1: was nothing like that out there. I think. More more
- 9:17Speaker 1: to the point, it was the Romans who just didn't
- 9:20Speaker 1: use zero, and the West was built by Rome and
- 9:25Speaker 1: um that's I think where the shunning of zero came from,
- 9:30Speaker 1: not necessarily from fear, but just because the Roman numeral
- 9:33Speaker 1: system doesn't have zero. Yeah. I found where. They flirted
- 9:37Speaker 1: with it at first, with nulla in U l l A,
- 9:41Speaker 1: which they would represent with a little inn, but it
- 9:44Speaker 1: clearly didn't take. No, they said it, We're not gonna
- 9:47Speaker 1: use it as zero. No, why would we ever need zero?
- 9:51Speaker 1: We don't need it as zero? Right did they talk
- 9:54Speaker 1: like that back then too? Yeah, like Vinny from Brooklyn, Sure,
- 9:59Speaker 1: I think so. Uh So where are we in India? Yeah,
- 10:25Speaker 1: we're in the fifth century a d in India and
- 10:28Speaker 1: a guy named um Ariba is possibly the person who
- 10:36Speaker 1: invented zero really possible or discovered as you like to say,
- 10:40Speaker 1: thank you, yes, thank you for correcting me with my
- 10:43Speaker 1: own words. That's when they are your articles. So UM,
- 10:49Speaker 1: it is pretty pretty much universally accepted that zero was
- 10:53Speaker 1: created or discovered in India, and then it spread pretty
- 10:59Speaker 1: quickly over for UM two UH Islamic nations, Arab nations, UM,
- 11:06Speaker 1: and the It was the Arabs who taught a guy
- 11:10Speaker 1: named Fibonacci Leonardo Pizza, who was a great mathematician of
- 11:15Speaker 1: the West in the I think the twelfth century or
- 11:19Speaker 1: the thirteenth century. You know, people are gonna say, do
- 11:21Speaker 1: the Fibonacci number. Go ahead, Well, no, no, no, people
- 11:25Speaker 1: are gonna ask for that podcast. In fact, they've already
- 11:28Speaker 1: been asking for that podcast. Do you want to do
- 11:30Speaker 1: that one? Do you want to maybe? Probably not? Well,
- 11:35Speaker 1: Fibonacci was um, the son of a customs officer in Algeria, Chuck,
- 11:40Speaker 1: and he had Arabic tutors, and they said, hey, kid,
- 11:44Speaker 1: we're gonna teach you how to really do math. Because
- 11:46Speaker 1: by this time, by the I think the twelve hundreds
- 11:50Speaker 1: UM or the eleven hundreds of the Salt century, UH,
- 11:54Speaker 1: the Arabs were very well versed in mathematics and the
- 11:57Speaker 1: West was still just complete idiots. Fortunately, Fibonacci was over
- 12:02Speaker 1: there getting tutored and he figured out, wow, this is
- 12:05Speaker 1: really really important, and introduced our Arabic numeral system which
- 12:10Speaker 1: we used today, uh, to the West through a book.
- 12:13Speaker 1: So you said he wrote a book. Did he write
- 12:15Speaker 1: the book? No, he wasn't the only one. Okay, No,
- 12:19Speaker 1: that's not true for the West. Yes, he wrote the book,
- 12:22Speaker 1: and then other people wrote treatises on his book. So
- 12:24Speaker 1: he pretty much said the basis. Yes, okay, he was
- 12:27Speaker 1: the fulcrum, the hinge between West and Middle East. A
- 12:32Speaker 1: zero is a fulcrum, Yes, it is interesting. Um. So
- 12:37Speaker 1: he was the one who introduced it to the West.
- 12:39Speaker 1: But again, I mean we say that because we're Western writers, chuck.
- 12:42Speaker 1: But it was very well established for hundreds of years
- 12:45Speaker 1: by the time Fibonaci heard about zero. Yeah. And you
- 12:48Speaker 1: also point out interestingly that simultaneously and completely independently of India, uh,
- 12:54Speaker 1: in Central America, the Maya were also uh beginning or
- 12:58Speaker 1: already using zero yeah to uh, mainly for their calendar. Right. Yeah,
- 13:02Speaker 1: it was there. It was the base of counting um,
- 13:06Speaker 1: which makes sense. It totally makes sense, and it makes
- 13:08Speaker 1: for a more accurate calendar. Right. So like for mine calendars,
- 13:12Speaker 1: like the day of the month would be zero day,
- 13:15Speaker 1: then one day than two day, than three day and
- 13:17Speaker 1: so on. How would you say that though, because you
- 13:19Speaker 1: say first, second third, how would you say they had um?
- 13:22Speaker 1: They had different names for today, like Zula would be
- 13:27Speaker 1: zul or you know, mon or something like that. It
- 13:31Speaker 1: was like the rather than first second third. They didn't
- 13:34Speaker 1: have numerals like that, like first second third that's Arabic.
- 13:38Speaker 1: So to the Maya, it was like zul day. Didn't
- 13:40Speaker 1: that Ghostbusters? I think so? But that was what Sumerian.
- 13:45Speaker 1: Oh yeah, zul was Sumerians all coming together. Um. So
- 13:48Speaker 1: that does make for a lot more accurate counting UM.
- 13:51Speaker 1: And that's one of the big flaws in our calendar,
- 13:54Speaker 1: the Gregorian calendar, is that there is no zero year.
- 13:58Speaker 1: Well and we all got that pointed out to us
- 14:01Speaker 1: quite uh through the through the media, especially when the
- 14:05Speaker 1: millennium turned. Because there's no year zero, our decades and
- 14:09Speaker 1: our centuries and our millennia um actually occur at the
- 14:12Speaker 1: end of that year and at the beginning, Like when
- 14:14Speaker 1: the clock struck midnight at two thousand and we all went, yeah,
- 14:18Speaker 1: new millennium, not so we still had a year left,
- 14:21Speaker 1: that's right. Have we started counting from zero then? Yeah?
- 14:24Speaker 1: In January first two thousand that would have been the
- 14:26Speaker 1: start of the new millennium. But the the we started
- 14:30Speaker 1: counting from one so one to two thousand years rather
- 14:34Speaker 1: than two thousand years. And there was one guy in
- 14:36Speaker 1: every bar trying to point out to as many people
- 14:39Speaker 1: as he could do you realize it's not even true,
- 14:42Speaker 1: and he's like, why isn't anyone buying me drinks? So
- 14:46Speaker 1: why did? Why are they going to beat me up? Um?
- 14:50Speaker 1: And I put a little a little notation in there
- 14:54Speaker 1: because I have trouble wrapping my head around that sometimes.
- 14:58Speaker 1: But the point is is there's ten single digit numbers
- 15:02Speaker 1: in the Arabic numerical system that we use, and at
- 15:06Speaker 1: zero through nine, anything beyond that isn't in the tens
- 15:09Speaker 1: columner above, and thanks to zero, we have a ten
- 15:12Speaker 1: column exactly. Take a chuck. Uh. Well, Western astronomers they
- 15:20Speaker 1: came up with a system late seventeenth and early eighteenth
- 15:23Speaker 1: century that designated calendar year one b C is zero
- 15:28Speaker 1: and then basically anything above or below that would either
- 15:30Speaker 1: be plus or minus so a B C or a
- 15:34Speaker 1: D right, so uh two a D would be minus
- 15:38Speaker 1: one or no two BC would be minus one bc. Yes,
- 15:43Speaker 1: since we're not living in a d They just kind
- 15:45Speaker 1: of screwed with the BC a little bit. So right
- 15:47Speaker 1: now we're in plus two thousand twelve. Yes, which also
- 15:52Speaker 1: makes I mean, it's not just calendars. I mean zero
- 15:55Speaker 1: lies between negative one and one and serves as a
- 15:58Speaker 1: full corum point for basically all numbering. Yeah, positive and negative.
- 16:03Speaker 1: And that was Jacques Cassini who came up with that,
- 16:05Speaker 1: um astronomical calendar. What the Italians are all up on
- 16:08Speaker 1: this stuff, weren't they. Yeah, it'soking to be French, but
- 16:11Speaker 1: yeah it is an Italian. Yeah, who knows, maybe he's
- 16:14Speaker 1: Northern Italian. Yeah, exactly. Um, but yeah, so they he
- 16:19Speaker 1: basically said, well, wait, why don't we just choose one
- 16:22Speaker 1: year to be zero, and then we'll just basically make it.
- 16:24Speaker 1: We'll make the calendar based on zero's rightful place in numbering,
- 16:27Speaker 1: which is precisely between one in negative one. There's a
- 16:32Speaker 1: zero there. It doesn't just go from negative one to one.
- 16:34Speaker 1: Zero is, like you said, the full crumb of all numbers.
- 16:37Speaker 1: It spreads out infinitely on either side. So it's not
- 16:40Speaker 1: positive and it's not negative, and um, so it's the
- 16:44Speaker 1: only number that is non positive and non negative. But
- 16:47Speaker 1: it's neither a positive number nor a negative number. Wrap
- 16:50Speaker 1: your head around that one. Yeah, you college students sitting
- 16:53Speaker 1: around here at midnight, just gaze up at the stars
- 16:55Speaker 1: and try and figure that out. Start counting, Start counting.
- 16:58Speaker 1: It's also an integer whole number, right, Yes, and h
- 17:03Speaker 1: is very handy when it comes up to ratios and fractions,
- 17:07Speaker 1: because a fraction can be written in a couple of ways,
- 17:11Speaker 1: either with the one on top of the other or
- 17:14Speaker 1: with a little decimal point. Yes, and without those zeros,
- 17:17Speaker 1: you wouldn't be able to do that. No, So this
- 17:20Speaker 1: decimal system, um, basically you can look at it as
- 17:25Speaker 1: anything to the right of the decimal So that tends
- 17:29Speaker 1: the hundreds, the thousands, right, the th ten, hundreds about
- 17:34Speaker 1: thank you. Yeah, you're getting as bad as um. They
- 17:38Speaker 1: those are all encapsulated in that zero that's up to
- 17:42Speaker 1: positive one, right, yeah, because it's less than a whole one.
- 17:46Speaker 1: But it's not so much that it's negative one, right,
- 17:49Speaker 1: it's encapsulated by that zero. So all of these ratios,
- 17:52Speaker 1: all of the decimal system, gives us these incredibly precise numbers.
- 17:57Speaker 1: Whereas we can count in whole numbers to the right
- 17:59Speaker 1: of zero in positive whole numbers that just goes on
- 18:03Speaker 1: and on and on and measures the vastness of the universe.
- 18:05Speaker 1: To go the other way, to go in this infinite
- 18:08Speaker 1: decimal system that's encapsulated within zero, lets you measure the
- 18:12Speaker 1: infantismal right, Yeah, so it's not like, oh it's between
- 18:16Speaker 1: two and three, right, I mean, try making like high
- 18:20Speaker 1: quality machine parts using whole numbers. You can't know, it
- 18:24Speaker 1: can't be done. So there's all sorts of things that
- 18:26Speaker 1: would have never taken place. Head zero not given rise
- 18:29Speaker 1: to the decimal system, or everything would be really big. Yeah,
- 18:32Speaker 1: you know, everything would be like twice as large, Like
- 18:34Speaker 1: the ten thousand year clock wouldn't even work. Remember they
- 18:36Speaker 1: were using like fractions of an inch that still wouldn't work. Um,
- 18:41Speaker 1: what else, Chuck, Well, you point out very astute lee
- 18:45Speaker 1: some odd properties of zero, and they are actually called
- 18:49Speaker 1: the properties of zero because it's such a weird number
- 18:52Speaker 1: that you have to have properties to explain it exactly.
- 18:56Speaker 1: So the which is the first one called, is the
- 18:58Speaker 1: additive property of zero row addition property. Yeah, add zero
- 19:03Speaker 1: to anything and you're gonna get that same thing. That
- 19:05Speaker 1: sounds very basic. Same with subtracting. Sure, five plus zeros five.
- 19:10Speaker 1: Zero is five, right, and it is very basic. But
- 19:13Speaker 1: zero is the only number that doesn't affect another number
- 19:16Speaker 1: when it's added or subtracted to it, which is important.
- 19:20Speaker 1: It is anytime a number is the only thing of
- 19:23Speaker 1: its kind, it's worth mentioning. Like pie. There's um, which
- 19:27Speaker 1: by the way, wouldn't exist without zero in the decimal system,
- 19:31Speaker 1: or any of those wouldn't exist. To us. Um, there's
- 19:34Speaker 1: the additive inverse property of zero, where any numbers that
- 19:39Speaker 1: add up to zero are additive inverses of one another.
- 19:43Speaker 1: So negative five plus positive five, or just five as
- 19:48Speaker 1: they call it in positive land, equal zero. So negative
- 19:51Speaker 1: five and five are additive inverses of one another. Multiplying
- 19:56Speaker 1: from the time you're I think I learned in the
- 19:58Speaker 1: second grade my multiplication tables, if I remember correctly, Ms.
- 20:02Speaker 1: Anderson and Ms. Temple, thank you very much. Uh. They
- 20:06Speaker 1: taught me that if you multiply any number by zero,
- 20:09Speaker 1: you're going to get zero. And as you point out,
- 20:12Speaker 1: that multiplication is really just a quicker way of adding things.
- 20:17Speaker 1: It's a shortcut. Yeah, it's a shortcut. So uh. The
- 20:21Speaker 1: idea that a number can be added zero times uh,
- 20:25Speaker 1: or that zero can be added to itself. That's when
- 20:28Speaker 1: I get the most. Yeah, it's just doesn't make any sense.
- 20:31Speaker 1: Like you like five times zero doesn't mean zero place
- 20:34Speaker 1: zero place ero place zero place ero, that doesn't mean
- 20:36Speaker 1: anything zero. Yeah, right, what about dividing by zero? Let
- 21:09Speaker 1: me ask you? No, let me This is the part
- 21:11Speaker 1: where I was like, nobody understands this. I don't feel
- 21:15Speaker 1: very bad about this because no one really understands it. Um,
- 21:19Speaker 1: there's no So there's these other properties of zero that
- 21:21Speaker 1: cover like additive, inverse, addition, subtracting, multiplication. There is no
- 21:26Speaker 1: property that says why you can't divide by zero because
- 21:30Speaker 1: it's so nonsensical. It doesn't even exist. The concept of
- 21:33Speaker 1: dividing by zero doesn't really actually exist except in you know,
- 21:38Speaker 1: the imagination of people. I bet mathematicians have tried, though,
- 21:42Speaker 1: like frustratingly tried. You can't. There's nothing you can do,
- 21:47Speaker 1: and they don't even fully understand why. But the um.
- 21:51Speaker 1: The best explanation that I saw was that it has
- 21:54Speaker 1: to do kind of with the multiplication property right to
- 21:57Speaker 1: where if you divide something, so like six divided by
- 22:00Speaker 1: two equals three, So if you can divide a number, Um,
- 22:04Speaker 1: the result of that number by the divisor so in
- 22:09Speaker 1: this case, three and two multiplied by one another should
- 22:13Speaker 1: equal the dividend, which is six. Now if you divide
- 22:16Speaker 1: six by zero, right, it doesn't equal anything. It should
- 22:21Speaker 1: equal zero. If you multiply it, it's not gonna equal
- 22:24Speaker 1: to Uh. That's the best example I could come up with. Yeah,
- 22:29Speaker 1: that makes sense, so it shouldn't. Well, I mean, you're
- 22:32Speaker 1: completely insane. It makes sense that it doesn't make sense. Okay,
- 22:35Speaker 1: that's what I'm saying. And Stephen right head a joke.
- 22:37Speaker 1: He said that black holes are where God tried to
- 22:40Speaker 1: divide by zero. Wo. Like, that's good, Steven right his Uh,
- 22:50Speaker 1: I still did that his one bit Sometimes when um,
- 22:53Speaker 1: people get in a car with me, I say, hey,
- 22:55Speaker 1: put your seat belt on. I want to try something.
- 22:57Speaker 1: That was one of his jokes. He's like, just try
- 22:59Speaker 1: that when the someone gets in a car, he's good. Um.
- 23:02Speaker 1: And then also there's the property of zero exponent, which
- 23:05Speaker 1: also doesn't make any sense. Chuck, there's um you know,
- 23:07Speaker 1: there's negative exponents, like numbers to the negative power tend
- 23:10Speaker 1: to the negative five. Yes, because of this, mathematically it
- 23:14Speaker 1: works out, but I don't understand it. UM numbers to
- 23:17Speaker 1: the zero power equal one. That doesn't make any sense
- 23:20Speaker 1: because zero multiplied by something should equal zero, not one.
- 23:26Speaker 1: That's how it works out, though, magical mysterious number at
- 23:30Speaker 1: my hero zero and I ran across one other thing
- 23:33Speaker 1: that I thought was pretty cool. Um. The the the
- 23:36Speaker 1: evidence of UM Islamic countries comfort with zero concept and
- 23:43Speaker 1: Western countries discomfort with it can be found still today
- 23:46Speaker 1: on elevators in countries where the Ottoman Turks or UM
- 23:51Speaker 1: any other Islamic nation UM conquered and ruled for a while,
- 23:56Speaker 1: you're still going to find evidence of a comfort with zero,
- 23:58Speaker 1: like in Hungary. If you look in Spain. I here too,
- 24:02Speaker 1: if you look on an elevator, the ground floor is zero,
- 24:05Speaker 1: and any floor beneath that is a negative number, really
- 24:09Speaker 1: like the basement parking, like negative one, negative two. Huh
- 24:13Speaker 1: isn't that cool? And apparently that's because of the presence
- 24:17Speaker 1: of the Turks who were there for a while. Wow, yeah,
- 24:20Speaker 1: I mean they didn't have elevators then, but apparently, like
- 24:22Speaker 1: the that's like, you don't see a floor zero in
- 24:25Speaker 1: the West, No, you don't. We just don't like zero
- 24:28Speaker 1: that much or a fourth thirteen, all right, although it
- 24:31Speaker 1: is thirteen. We've had that talk before. I think, yeah,
- 24:35Speaker 1: what do we have here? P? One, P two in
- 24:37Speaker 1: our building? Definitely not negative. Let's say that from now on,
- 24:41Speaker 1: like what love you parked on? I'm on negative four,
- 24:44Speaker 1: I will say that. I will say that right now,
- 24:46Speaker 1: I'm on negative three. I'm on negative two. Go and
- 24:51Speaker 1: chuck um. And also, let's see you can type zero.
- 24:56Speaker 1: You got anything else? You're just happy to be done
- 24:58Speaker 1: with this one? No, this was actually really good. Um,
- 25:01Speaker 1: I don't know about that. Zero is my hero a
- 25:04Speaker 1: magic number. If you type in zero and this is
- 25:08Speaker 1: the search bar how stuff works dot Com, it will
- 25:10Speaker 1: bring up this article, including a cool little story that
- 25:13Speaker 1: we didn't get to about a great parent. True. Uh.
- 25:17Speaker 1: And also I highly encourage if if this even piqued
- 25:20Speaker 1: your interest at all, I highly encourage you to read
- 25:23Speaker 1: zero in four Dimensions, which is an article you can
- 25:26Speaker 1: find online from two Thou Too by a guy named
- 25:28Speaker 1: Hassain Arsham, and he explains in much greater depth in
- 25:32Speaker 1: detail like zero and what's so cool about it? Or
- 25:36Speaker 1: if you want to really get into it, Robert Kaplan
- 25:39Speaker 1: wrote a whole book on it, we should do one
- 25:40Speaker 1: on three al right. I pitched that article a long
- 25:44Speaker 1: time ago. A long time ago, remember on on three,
- 25:47Speaker 1: I remember, so those would be our two. I'd have
- 25:50Speaker 1: to write it down, so I don't know if it'll
- 25:52Speaker 1: ever happened, get to it. I wrote this so we
- 25:54Speaker 1: could do this. You're more of a man than me, um,
- 25:58Speaker 1: I think at some point in the not too distant past,
- 26:01Speaker 1: Chuck I said search bar, So that means it's time
- 26:04Speaker 1: for listener mail. Indeed, I'm gonna call this, uh coffee
- 26:10Speaker 1: including coffee song from a listener. Okay, this is from Ashley.
- 26:15Speaker 1: Great work on the Coffee podcast, gents. I could have
- 26:18Speaker 1: saved my last four years of work at a cafe
- 26:21Speaker 1: just by listening to y'all. Really though, it was a
- 26:25Speaker 1: splendid way to spend my days getting to know the
- 26:27Speaker 1: locals in downtown Edmonton, Alberta, Canada, North America. Have we
- 26:33Speaker 1: entered the song yet? Because she rhymed a second in case, no,
- 26:37Speaker 1: that is not the song. Okay, that's coming. Uh, She's
- 26:40Speaker 1: just a rhymer by nature. I think. While I can't
- 26:42Speaker 1: say I'm a total coffee snobber expert, I do have
- 26:44Speaker 1: a thought on the old wise Starbucks, so better debate.
- 26:47Speaker 1: I think that part of the taste comes from the
- 26:49Speaker 1: number of beans used in the blend. For instance, at
- 26:52Speaker 1: the cafe I used to run, we served both Milano
- 26:55Speaker 1: Coffee and then Umbria. I believe that each of these companies,
- 26:59Speaker 1: plus a coffee I now drink called Intelligentsia, contains a
- 27:04Speaker 1: blend of beans as many as fifteen different kinds to
- 27:07Speaker 1: create that smooth balance I really love. In my americanos,
- 27:11Speaker 1: it's her last name Starbuck. No no no, no, she's saying
- 27:15Speaker 1: Starbucks doesn't use the blend, so it's more better. Her
- 27:18Speaker 1: name is mom and pop her last name. As far
- 27:22Speaker 1: as I understand, Starbucks may use this view as one
- 27:24Speaker 1: to three types of beans and their espresso blend. Like
- 27:28Speaker 1: I said, I think this may be a part of
- 27:29Speaker 1: the story, but not likely the whole story. On another note,
- 27:33Speaker 1: since leaving the cafe, I now work with a group
- 27:36Speaker 1: of software nerds who used to visit my cafe on
- 27:39Speaker 1: a regular basis. So now I too, get to go
- 27:42Speaker 1: for coffee every day. It's one of the parks of
- 27:44Speaker 1: the job, pun intended. We have, uh, we even have
- 27:47Speaker 1: a little coffee song. And she recorded this and sent
- 27:51Speaker 1: it to us, so we're going to play that right now. Coffee, coffee, coffee,
- 27:56Speaker 1: coffee all day long. When I eat some coffee, I
- 27:59Speaker 1: sing the coffee song. Well that's the g rated version
- 28:02Speaker 1: I learned. So how about that, Josh, that was something else.
- 28:07Speaker 1: Thank you Ashley for that. Yeah, thanks a lot, she says,
- 28:10Speaker 1: As you can tell, we're a bit mad about our
- 28:12Speaker 1: coffee drinking. It's the new smoke break for us. What, um,
- 28:18Speaker 1: where where where is that person? She didn't say, Oh no,
- 28:22Speaker 1: she did say, I'm sorry, Edmonton, Alberta's earth. That's right. Well,
- 28:25Speaker 1: thank you very much for that. We appreciate you and um,
- 28:29Speaker 1: your co workers for making that song, for listening, for
- 28:33Speaker 1: drinking coffee, indeed for caring. That's great. Yeah. Um, if
- 28:37Speaker 1: you have a song, Chuck. We get them from time
- 28:40Speaker 1: to time and I feel like we should we should
- 28:41Speaker 1: be better about playing them. Yes, Uh, we want to
- 28:44Speaker 1: hear it. You can, I guess make it as like
- 28:48Speaker 1: an MP three, MP four. MP three is good, right, Jerry?
- 28:52Speaker 1: MP three? Uh, and uh you can send it to us.
- 28:57Speaker 1: You can tweet to us and tell us it's on
- 28:58Speaker 1: the way a s y SK podcast. You can go
- 29:02Speaker 1: onto Facebook can tell us it's on the way. At
