"Reducing the number of revolutions per minute," Mr. Foster explained. "The surrogate goes round slower; therefore passes through the lung at longer intervals; therefore gives the embryo less oxygen. Nothing like oxygen-shortage for keeping an embryo below par." Again he rubbed his hands.

"The lower the caste," said Mr. Foster, "the shorter the oxygen." The first organ affected was the brain. After that the skeleton. At seventy per cent of normal oxygen you got dwarfs. At less than seventy eyeless monsters. (1.70-4)
Science is being abused here for purposes of harm; notice that this new world hasn't made smarter men to fill the role of Alphas; it has simply degraded everyone else.
Quote 2
Henry Foster had had his machine wheeled out of its lock-up and, when Lenina arrived, was already seated in the cockpit, waiting.
"Four minutes late," was all his comment, as she climbed in beside him.
[…]
"There's the Red Rocket," said Henry, "just come in from New York." Looking at his watch. "Seven minutes behind time," he added, and shook his head. (4.1.29-32)
Henry's character reflects an obsession with exactitude in the new world.
Quote 3
"Phosphorus recovery," explained Henry telegraphically. "On their way up the chimney the gases go through four separate treatments. P2O5 used to go right out of circulation every time they cremated someone. Now they recover over ninety-eight per cent of it. More than a kilo and a half per adult corpse. Which makes the best part of four hundred tons of phosphorus every year from England alone." Henry spoke with a happy pride, rejoicing whole-heartedly in the achievement, as though it had been his own. "Fine to think we can go on being socially useful even after we're dead. Making plants grow." (5.1.5)
Science has dehumanized even death. Henry's admiration of this process reflects how deeply ingrained is the lesson that individuals exist only to serve the community.
