- Sgt. Grice: I'm going to make ruddy BBC announcers out of you lot if I have to soften up your gullets with my bare hands!
- [Dillon and Grice are about to leave their radar site to investigate a meteorite impact they tracked]
- Sgt. Grice: [to the Private watching the radar screen] You carry on. Just report that plane when it shows up. Nothing else. Got it?
- Private: Yes, Sergeant.
- [Dillon and Grice leave]
- Private: It's the one I learnt yesterday, Sergeant.
- Dr. Leo Pugh: I joined your father as a mathematical genius. That's not boasting. I was, once. A calculating boy. But these machines, they beat me. I press buttons.
- Paula Quatermass: Why did you join him?
- Dr. Leo Pugh: Looking for some kind of beauty, I suppose. The mathematical kind. The idea of making roads in space for rockets to travel. Four-dimensional roads curved with relativity, metalled with best quality continuum. Hmm.

- Dr. Leo Pugh: These roads are two-way...
- [Pugh tries to go back to work. Paula stops him]
- Paula Quatermass: The break's still on Leo. Tell me about the calculating boy.
- Dr. Leo Pugh: Ohh. At the village school, in Marianglas, the teacher, old Miss Williams, used to set me enormous sums to do. She loved to astonish herself, 'cause I always got them right. "You'll go far, Leo bach," she said. "You have the power to benefit mankind." Hm, and now I press buttons.
