How does your brain feel about calculating the surface tension of the domain walls?
那你的大脑对于计算畴壁的表面张力怎么看？
生活大爆炸 第9季
Well, now that you can focus again, what do you say we get back to surface tension of domain walls?
现在你的注意力又能集中了，咱们可以回到畴壁表面张力的研究了吧？

Domain wall
A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model. Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is the metastable vacuum.
