Huxley is describing the sound of a helicopter decelerating. Huxley demonstrates his profound talent through this use of metaphor.
Although Bernard Marx is an Alpha, his short height makes him feel as if he does not belong amongst the high caste. As a result, he is incredibly rude to his inferiors, as well as to other members of his own caste.
This is a controversial argument in today's society: does height really matter? Studies suggest that it does: in the end, height affects perceptions of leadership ability. Taller men are perceived as more commanding than shorter men. Studies have regularly shown that random people will pick the tallest person from a group as being the most commanding, even though in reality he might be inferior in rank. The honour guards in most militaries around the world regularly induct only the tallest men.
Because of the perceptions that have been built up by our society, shorter men can feel inadequate and insecure, even if they have superior abilities. Despite what every feel-good guide and common sense may tell us, height unfortunately does matter in our society.
Every person in the new world is conditioned to be useful to society, with each given a specific role. These are split into groups named after Greek letters: Epsilons, Gammas and Deltas do lower, less complex work, whereas Alphas and Betas are allocated higher, more complex jobs.
This reflects a functionalist theory of education called Role Allocation, put forward by Parsons and built on by Davis and Moore. Through testing intelligence, aptitude and ability, this system ensures that the most talented students will be allocated the more complex jobs (e.g. in medicine or law).
In Brave New World, Role Allocation takes place before the child is even decanted, and each child can be grown and conditioned from birth to meet the specific requirements of their job. Not only is each person suited perfectly to their role, they are also conditioned to be fully satisfied with their caste and position in life.
Westminster Abbey is a large gothic church in London, opposite the Houses of Parliament.
It is the traditional place of coronation and burial for English and British monarchs. As such, it is a significant building in British history. By transforming it into a venue for cabaret, Huxley demonstrates the lack of respect that the new world has for both religion and history.
A Solidarity Service has many parallels to a Christian mass. It is intended to bring members of the same caste closer together and closer to Ford (G0d). As in a Christian service, hymns are sung: Make Us One, Come Greater Being, and Rejoice In The Greater Being.
In a religious service, sacred food may be consumed or sacred objects worshipped. Ritual words or prayers might be recited. Here, a cup of soma is passed around, and each person recites specific declarations before they drink (e.g. "I drink to my annihilation").
The service may resemble a mass, but its values are a mockery of traditional religious values. The Solidarity Service ends with an orgy ("orgy-porgy"), encouraging participants to give in to their desires.
The 'T' symbol replaces the Christian sign of the cross. This is a reference to Henry Ford's Model T automobile, the vehicle that "put America on wheels".
The Model T stands for mass production and affordable prices. These are the ideas on which society in Brave New World is built. In the new world, the people are themselves mass produced and every good is affordable and readily available to everyone.
