love a) how Eugenia sets Stephen back at first, b) how he soon adapts, c) how quickly they then play and improvise off each other - quick and fun lol

I am a mathematician not a calculator.... Wish i could have told that to my teacher

She is now one of my favorite people ever! :D

She actually makes maths fun! What a character. She should be on the show more often.

"I can't do this. I'm a mathematician, not a calculator." THANK YOU. Being a pure math major, I am expected to do the calculations all the time when it comes to splitting checks, etc. Realistically, I stop doing purely calculations by the end of calculus III. Not that I don't enjoy or can't do calculations, but math is definitely beyond that. For the next 2 years after calc, I study theory and proofs. There's so much more beauty behind theory and analysis...(nerding out). Anyhoo, Eugenia is the best! Passion for math and baking like this are what we need hehe. Also, I am so glad Stephen is now hosting the Late Show. He's so funny & he has one of the most diverse group of guests! :) Keep up the good work!

My suspicions were correct, living in Sheffield does slowly turn you insane.

She would be a great regular guest on the show. There was some good chemistry there. Just go ahead and cover all the subjects.

In my math class at school, i learnt that 5318008 on a calculator upside down spelt BOOBIES

Is it me, or are the guests of this show already more diverse than all other shows?

Did she basically just make a butter burrito?

She was one of my lecturers at Sheffield. She was this energetic and amazing and one of the most inspiring lecturers I had.

What a delightfully strange lady. :D I wish I had her as a math teacher when I was in high school.

Oh man, I love this woman. And that Invention 13 remix at the end, very nice touch. Bach and mathematics go very well together.

This is the kind of teacher the mean kids at my school would relentlessly make fun of and back in my days, almost all those kids were mean. She wouldn't have survived there. Thankfully she's teaching somewhere her students are older and more appreciative.

That woman is insane. I'm in love.

if matt damon can beat up half of bosten and still be good at math. I dont see why this woman can't be a little nuts and still be a math genius. Inteligence at this level is basically a gift from god. Having said that this doesn't mean she didn't have to work extremly hard to reach her full potential.

She sounds like a joy to hang out with, arms flailing everything.

You must bring her back!😁

I love when I see someone so excited about their work.

I want to see more of her, because... reasons.

What a peppy lady. She must be an awesome teacher in class.

I had a few teachers like this and they always really knew how to get to me and get me to push myself and learn more and want to participate and everyone was always eager to learn

She's the Tom Cruise of math

Her enthusiasm is contagious. And delightful.

I LOVE HER. I wish she taught me math throughout my education-- maybe I would have enjoyed it more. My teachers told me I was good at math, but I never felt any joy for it. I think this fab lady could have made me seen the joy in math.

she is nuts! I love her!

Her passion and energy is commendable.

I wish my maths lecturer was this interesting.

puff pastry is exactly why everyone loves the french. Although it's usually easier to just soften the butter at room temperature. this looks more fun though.

Her enthusiasm is contagious!

Love this. She's so wonderfully kooky and ridiculously brilliant. Please have her back!

"i'm a mathmetician not a calculator" - ouch stephen

Steven learns an important first lesson about math; mathematicians are crazy (which I mean in the best way possible).

Awww so sweet. Wish all my daughter’s math teachers were like her.

Just discovered her 2 minutes ago, love her already

Damn, Eugenia has come a long way since her Catsters videos.

3:30 54 times 3 = 162 NOT 172

I had her as a teacher last year

She has a channel called the Catsters where she teaches Category Theory.

I met her at lecture! I had her book signed. An amazing woman.

Holy shit, I remember this lady...she performed in Chicago a few years back. Damn, so she is a doctor too? That's crazy...

when stephen gets 18 and she congratulates him he genuinely looks like a happy student, it's adorable

Stephen, it's 162, not 172. But Eugenia is correct; math isn't about multiplying big numbers together. It's about finding patterns. For example, how did I notice that 172 is not the correct answer? There's a pattern in multiples of 3: the sum of the digits of any multiple of 3 is also divisible by 3, and this is not true for 172. Why is this pattern true? That is a great motivation to learn beautiful subjects like modular arithmetic. I wish math classes focused more on this than mindless calculation.

I would watch her cooking show if it's there... Really funny

Former actuarial science major: math professors at this level get off to numbers.

Well I like her now. I wish I had a teacher like that.

i love her energy,, very pretty as well

Her energy is awesome

There are not 4372 layers. When she folded 2 layers without putting butter in between, they stuck together and become one layer.

She's so excited! I love it!!

I hated math in high school, but I decided to be a math major in college when I took a (pure) math class with an amazing professor. In my last year of college Dr. Cheng came to my college and taught that same first class that I took. I wish I could've been there…

Bring her on again!

did anyone else notice that Stephen got 54x3 wrong? 162, not 172 😄

she needs a show! totally awesome!

They worked well together.

This was really cool, I hope he keeps this kind of stuff up. Fallon did a bunch of kid sciencey stuff when he first started, but we've all seen that fall off once less attention was paid to his show. I hope Colbert keeps it up.

Why do you need a thousand Lairs? Once you have one, Hatcheries will do you. You're just wasting minerals and vespene, Dr. Chang. On the other hand, layering math is basically like taking that number, 2, and sticking it inside of a mech inside of a mech inside of a mech inside of a mech inside of a mech (this is a fairly complicated process). So in strictest mathematical terms, her equation of 2x3x3x3x3x3x3x3= Super Tengen Toppa Gurren Lagann.

Pretty sure this isn't on the secret menu at Chipotle.

She'd be everyone's best mathematics teacher.

Eugenie Allen's middling short story/brand name "Cake Math," which she made her family read aloud in DC/FD16, must've been a tribute to this brilliant mind's "π MATH", ya think? I'll ask "Cynthia d'Aprix Sweeney"!?

she's brilliant!

I am a retired art teacher who used to do 'math art' with my students particularly during the years that I taught art in Saudi Arabia. I would be very interested to hear and see more about what you call and do as math art.

as a baker, she is not making a really good puffy pastry!the butter is seeping!

I did like to watch Eugenia at A Trip to Infinity, a netflix documetary, she has a beautiful voice!

I wish she was my math teacher when I was in school.

This was really kind of adorable

she needs her own show

54 x 3 = 172... Stephen The Calculator.

Ah Eugenia Cheng

"I'm a mathematician not a calculator." ... *slow clap*

SHE'S GREAT!

She’s a sweetie pi.

"I'm a mathematician, not a calculator". Perfect.

she's like a female Russel Brand. The first minute at least is just like his personality lol

54 * 3 = 162 not 172

I remember cooking with students and when we had to increase a recipe, I overheard students saying, "Now I get why I need math!"

She has a funny charm to her personality, very high energy but casual

Hmm... if you take a thousand layer cake and divide it into three, you only add two more layers, not multiply it by three, no??? Then if you add two layers of strawberry cream, that's two more layers - a total of four layers added once split and served. Methinks the math is slightly off a smidge.

She is just awesome!!!!

I love this! I wish she was my math teacher!

I love this woman

Ms. Frizzle: Maths Baker

hey Eugenia! shes my math teacher!

I've got to read her book

Dr. Eugenia Cheng is awesome!

Adorbs, love it.

This was so awkward, but I love it.

math people are so cute when they express their love for their profession. im like "yeah, yeah... math stuff.... yeah!" on the inside im like "what PLANET AM i on?"

Well that was adorable.

Anyone else a little disappointed she didn't drop serious & complicated mathematical knowledge? Pure mathematics sounds like some next level shit

I wonder if they had to tell her not to say Maths

Dammit why couldn't I have had a teacher liker her in school?

i think she is more philosopher than a mathematician........

colbert has really tried hard to play up the sex appeal ever since he took over the late show....and i think it's working ..

This, kids, is why you shouldn't smoke crack.

Wonderful.

... Stephen would be a handsome teacher, I would not miss any lesson.

A brilliant, absolutely gorgeous woman who can bake? I'll take one.

Awesome guest!

make this a weekly thing!
