Quotes 

• Penny Hofstadter : [knock knock knock]  Sheldon?

  Penny Hofstadter : [knock knock knock]  Sheldon?

  Penny Hofstadter : [knock knock knock]  Sheldon?

  Sheldon Cooper : [opens door]  It's annoying when you do it.

• Leonard Hofstadter : Thought you were getting us dinner.

  Penny Hofstadter : Sorry. I had to stop at Sheldon's and help him solve string theory.

  Amy Farrah Fowler : [dumbfounded]  What?

  Penny Hofstadter : Yeah, turns out the answer's knots.

  Leonard Hofstadter : That's cute, but you can't have knots in more than four dimensions.

  Penny Hofstadter : [heading towards the bedroom]  Mm... you can if you consider them sheets. Good night.

• Penny Hofstadter : Oh, Amy, you're here. Again.

  Amy Farrah Fowler : Yeah, Sheldon said he needed another night to work, so I said I've give him some space.

  Penny Hofstadter : So what's all this?

  Leonard Hofstadter : Well, Amy and I were talking about old science fair projects and how fun it would be to re-create them.

  Amy Farrah Fowler : We're making hot ice.

  Leonard Hofstadter : It's pretty... cool.

  Amy Farrah Fowler : [high-fiving]  Oh, nice one.

  Leonard Hofstadter : Turns out we both did this as our science fair projects in ninth grade.

  Amy Farrah Fowler : Do you remember any of your high school projects?

  Penny Hofstadter : Uh... well, I remember telling Jenny Runyon that I would teach her how to flirt with boys if she put my name on her project. I got an "A", she got pregnant.

  Amy Farrah Fowler : Girls like you are why I had to come straight home after school.

• Raj Koothrappali : Hey! Look what I got everybody.

  Leonard Hofstadter : Newspapers? Did you find a portal back to the 1990s?

  Penny Hofstadter : No. If he had that, he'd be trying to prevent *NSYNC from breaking up.

  Raj Koothrappali : Oh, please, I'm glad they broke up. Otherwise, Justin would never have brought sexy back.

  Sheldon Cooper : One thing you can't get on an iPad, the smell of ink and paper. One more reason iPads are better.

• Leonard Hofstadter : What are you doing?

  Penny Hofstadter : Making a boat. When I was a kid, my dad showed me how.

  Leonard Hofstadter : Boy, you'll do anything to avoid reading.

• Penny Hofstadter : I brought pizza.

  Sheldon Cooper : Oh, thank you. I have been working pretty hard. I... I could use a break.

  Penny Hofstadter : What's that?

  Sheldon Cooper : Oh, yeah, that is an experiment to see how many parallelograms I could draw while holding my breath.

  Penny Hofstadter : [seeing a parallelogram with a squiggly edge]  Is that where you blacked out?

  Sheldon Cooper : [pointing to a spot behind the couch]  No, actually, that's where I blacked out.

  Penny Hofstadter : And this?

  Sheldon Cooper : That is a list of all the different types of natural disasters.

  Penny Hofstadter : Firequake?

  Sheldon Cooper : I made that one up. Which I shouldn't have, because now I'm scared of it.

• Sheldon Cooper : I have a confession. When I berated Leonard, it was a clever ruse to conceal the fact that I'm not working on anything.

  Amy Farrah Fowler : Well, I think I speak for everyone when I say

  [sarcastic] 

  Amy Farrah Fowler : No!

  Sheldon Cooper : The truth is I have nothing of interest to pursue.

  Amy Farrah Fowler : Well, maybe this is the perfect opportunity to take some time for yourself and re-focus. I'm sure you'll find something you're excited about.

  Sheldon Cooper : Thank you, Amy. I don't know what I'd do without you.

  Amy Farrah Fowler : [cut to her entering the other apartment]  Hey, can I stay here? Sheldon kicked me out.

  Penny Hofstadter : Well, is everything okay?

  Amy Farrah Fowler : Yeah. He just wants some alone time to work.

• Penny Hofstadter : Hey, I thought you were working on actual science.

  Sheldon Cooper : I am. I'm trying to come up with a new approach to dark matter, but people keep distracting me. First, my mother kept answering the phone when I called, even though she knew I was busy. And now you show up with my favorite shape of food: a circle made of triangles served in a square box.

• Sheldon Cooper : And then I was thinking about inventing a new dark matter particle to evade the omega baryon contraints, but that just seems like something anyone could come up with.

  Penny Hofstadter : [not listening]  Mm. Agreed. You know what's blowing my mind? Somebody thought about putting cheese in this crust.

  Sheldon Cooper : I just wish I could find something that excites me.

  Penny Hofstadter : You... you do understand that crust doesn't normally come with cheese in it?

• Penny Hofstadter : What got you excited about dark matter in the first place?

  Sheldon Cooper : Well, I left string theory, which I'd been working on for a long time, and everyone was talking about how cool dark matter was, and I thought "Well, sure, I'll give that a whirl."

  Penny Hofstadter : So it's your rebound science?

  Sheldon Cooper : What's that?

  Penny Hofstadter : Well, not the science you spend the rest of your life with, but the one you use to make yourself feel pretty again.

• Sheldon Cooper : If I'm being honest, I never forgot about string theory. I mean, it's remarkable. It's the closest we've come to a theory of everything, something even Einstein couldn't figure out.

  Penny Hofstadter : Well, if he couldn't figure it out, maybe it's just wrong.

  Sheldon Cooper : But it's so elegant. I mean, look.

  [getting up and drawing on his white board] 

  Sheldon Cooper : String theory posits that the fundamental particles we see in three dimensions are actually strings embedded in multidimensional space-time.

  Penny Hofstadter : Interesting. So that would mean... that...

  [pause] 

  Penny Hofstadter : Can't do this by myself, buddy.

• Penny Hofstadter : So it's sort of like a guitar string, but instead of making an actual sound, each vibration is a different particle.

  Sheldon Cooper : Precisely. And when you express it in eleven dimensions, Einstein's relativity equations pop out. Does that sound like a coincidence?

  Penny Hofstadter : It does not.

  Sheldon Cooper : Yup. That's what I think.

  Penny Hofstadter : So... so, did we do it? Did we just solve string theory?

  Sheldon Cooper : [with a chortle]  Oh. I appreciate your enthusiasm, but this is not the sort of thing we can figure out in a night. People have been stuck on this for decades.

  Penny Hofstadter : What, decades? Really? It's... it's a string. How hard can it be? It-it... it's straight, it's in a loop, it gets knotted up with other strings. Uh...

  Sheldon Cooper : Well, actually, there are no knots in anything greater than four dimensions. Ooh, unless we get around that by considering them as sheets. You know, topologically speaking, that has a lot of interesting possibilities.

  Penny Hofstadter : See? How long did that take me, like a minute?
