Sigh - for sixty years, that "doodledoodledoo" has been wasting space in my all-too-limited brain. So I'm happy it brings a smile after half a century...
I wanted to point this out as well... the equation---assuming the second was on its own---is: 10 "beans" × 4 "beans" + 3 "beans" = 43 "rich coffee beans", or: _10B × 4B + 3B = 43R_ It's too early in the morning for me to work out the ratio of B(eans) to R(ich coffee beans), however.
Oh no, please don't go there :) It sounds like the imperial system of beans, which has different beans for measuring different things. Like the mile or ounce :)
The first result of B=1 or 0 makes perfect sense regardless of the equation! Nestlé is treating B^2 as equivalent to B, which can only be true when B=1 or 0
As a math teacher, I wish my students to get half excited... tenth get excited to see me as to seeing Cliff here in Numberphile. He brings up the student who I was in highschool, inventing my own math, loving every each way.
The equation of B^3 - B = 0 has solutions at B = 0, 1, and -1. This means that Nescafe could use negative beans in their coffee, and it'll still be fine!
Nope, that doesn't work. For the song to work lyrically, word for word, it needs to work for 40 cubed beans but also for 40 squared beans. Otherwise 4 beans times 10 beans plus three more beans cannot equal 43 beans, even if 4 beans is equal to 4 square beans.
This is so ridiculous, I love it! It reminds me of one of my university calculus professors who routinely stressed the importance of dimensions and accurate communication during his lectures. Rest in peace, Frank Goodman (f o g) -- your lessons are not forgotten!
I think it makes perfect sense if you look at coffee beans in measure theory. Put beans on a line at equal intervals - the number of beans is proportional to the total length. Put them on a 2d square lattice, the number of beans is proportional to the area (and so on). Now if you look at a 2d lattice set on a rectangle with 4 beans on one side, and 10 beans on the perpendicular side, it has an area of 40 beans (add 3 more beans and you indeed get 43 beans).
This is my first time seeing Cliff Stoll.. and I like him very much. And I’ll now always make sure to square my units, whether they’re coffee beans or not

Perhaps we should consider the possibility that bean is a contraction of boolean (so it really should be b’ean). In Boolean algebra anything squared is just itself (including variables… and perhaps units, too). So b^2 = b (and also b^3 = b). So in the end it’s just all beans.

That's funny because in "La Smorfia" which is the book used to traslate dreams into numbers you can play in lottery in Neaples folklore, the number of Coffee is 42
Why don't we consider "rich coffee beans" to be another variable? We'd have a system of two equations, one of which is linear and the other is quadratic, as follows: 2B×2B=4B 10B×4B+3B=43R, And then solve for B and R

THANK YOU FOR POINTING OUT THE PROBLEM IN THE UNITS!!!!!!!!!!!!!! It drives me absolutely wonkers whenever anyone doesn't pay attention to dimensionality.
If anyone is going to remember a coffee commercial from 60 years ago, it's Cliff. Matt Parker did a video about the math in a mnemonic meme to easily-ish remember something about the sine function. I think those two would get along well
There's one mathematical trick (you know, the ones where you eventually get 4=5 or 0=1 or whatever) where division by zero is hidden in division by X. So yeah, that stuff is important. :D
@@vsm1456 yeah, a better way would be to factor out 40 and B, 40B^2 - 40B = 0 40 * B * (B-1) = 0 Which leads directly to the factored form and thus the solutions
Hmm wouldn't the B = 1 solutions imply that the bean must be a dimensionless quantity? Seriousness aside, a hearty thank you as always for more delightful Cliff content.
All of these equations just imply that beans squared = beans, and therefore that beans = 1. So taking that information back to the original lyrics, that makes all the claims dimensionless: 2(1) * 2(1) = 4(1), yup that checks out; 10(1) * 4(1) + 3(1) = 43(1), that checks out too.

"4 beans times 10 beans and add 3 more beans equals 43 RICH BEANS"
Ans :
beans = 0 ,1 , (( (( -1 )) ))
43 RICH BEANS 😂🤣
One fell out... So there are 42 beans. If that is the answer then what is the question?
Beans is a name,
2, John, times 2, John, is 4, John.
Or rich coffee is a function taking the argument "beans" yielding a quadratic
So the roots of beans are 0, 1 and -1
So 2 beans times 2 is four beans. I don't think I would have picked up on that.

I love the way Cliff poses such interesting questions. His videos are truly multidimensional. Pun intended.
Cliff videos are an absolute treat.
@@topherthe11th23 I think Bryan might have meant to say negative length? You couldn't have a square with a side length of -2.
Apply the Dirac equation and derive the existence of anti-beans.
@@bongo50_ You're right, I meant length. Oops.
Negative distance is a thing when you consider 1-dimensional vectors
I'm just glad we weren't dealing with complex roots or we may have ended up with imaginary beans.
Cliff is back!!!
The release of these vids should become national holidays.
@@justsomeguy5628 someone make a petition for it
I've watched all of the Cliff Stoll Numberphile videos multiple times, but I've never laughed as hard at any as I have with this one!
Perhaps a “rich coffee bean” is a different unit from an ordinary “bean”
Rich coffee bean := (40/43 beans^2+ 3/43 beans)
@@zlatanibrahimovic8329 LOL YES
This may B my favorite Numberphile video to date
I could not stop laughing! You have really outdone yourselves. This might be the best Numberphile of all time!
Holy moly cliff at 11 years already has the shine in his eyes like everything in life is a wonder
I am really happy that Doc Brown solved the great mystery of the universe and moved on to studying coffee.
This is what makes time travel possible...43 rich coffee beans 🙃
THANK YOU FOR POINTING OUT THE PROBLEM IN THE UNITS!!!!!!!!!!!!!! It drives me absolutely wonkers whenever anyone doesn't pay attention to dimensionality.
If anyone is going to remember a coffee commercial from 60 years ago, it's Cliff.
Matt Parker did a video about the math in a mnemonic meme to easily-ish remember something about the sine function.
I think those two would get along well
I love that it's "easily-ish remember something about the sine function" because if it were easy you'd have been able to write it out completely.
The soundscape for this video was an absolute chef kiss 👌😂
This guy originally looks like Doc Brown from Back to the Future. And he not only looks like him... he also has the same energy!
This video and what the editor did just made my day
5:33 dividing by B means that B=0 must be excluded. But B=0 is also a valid solution of 40 B^2 = 40 B.
There's one mathematical trick (you know, the ones where you eventually get 4=5 or 0=1 or whatever) where division by zero is hidden in division by X. So yeah, that stuff is important. :D
@@vsm1456 yeah, a better way would be to factor out 40 and B,
40B^2 - 40B = 0
40 * B * (B-1) = 0
Which leads directly to the factored form and thus the solutions
I always make sure to never miss a Cliff video
This one jumped the shark. Just stupidly.
For some reason "I put 43 beans into a klein bottle" has the same energy as "I sawed this boat in half" and I'm all for it
Finally, the long-awaited sequel to 43 McNuggets!
This is the most pedantic complaint about a radio jingle I've ever heard, and I'm here for it.
"I put 43 beans into a Klein bottle"... of course you did, Cliff; it'd have been weird if you didn't.
More Cliff videos. Please and thank you.
This video delightfully fails to hide all the creative chaos around Cliff's house and mind
My goal ... no, my DREAM in life is to be as happy doing literally anything as this man is singing a 60 year old jingle.
60 years to solve the equation, meanwhile Nescafe invented Nespresso and kept making money as if nothing happened. Great episode guys, I loved it!
The positivity that he radiates shows how much of a person he is! So passionate
Hmm wouldn't the B = 1 solutions imply that the bean must be a dimensionless quantity?
Seriousness aside, a hearty thank you as always for more delightful Cliff content.
Well yeah. It is the way to keep the lyrics consistent. You have 43 dimentionless stuff in each portion of nescafe.
Bean = 100%, or simply "1".
A bean of zero dimension won't bring me what I need in the morning...
That’s just the best video I’ve seen all day
Btw, I love Cliff because he has this mad scientist vibe :)
The editing is delightfult
This was the most ridiculous numberphile video in a while. We love Cliff stoll
This is probably my favourite Numberphile video.
Of course he put 43 beans in a Klein bottle.
Love Cliff's workshop
I find it hard to believe that a man who finds such joy in solving equations has to use torn up cardboard boxes to write on.
Many a professors office have this organization style. 😄
My favorite professor's office looked a lot like Cliff's.
i love cliff, hadn't been into numberphile for a while and i had worried he might have passed away. glad to see he's still up to his antics 💙💙
All of these equations just imply that beans squared = beans, and therefore that beans = 1. So taking that information back to the original lyrics, that makes all the claims dimensionless: 2(1) * 2(1) = 4(1), yup that checks out; 10(1) * 4(1) + 3(1) = 43(1), that checks out too.
I took it to mean that a bean is a bean and nothing more. As you say, it is not a dimensional unit.
