- Bassist Roger Waters wrote “Part 2” as a protest against rigid schooling, particularly boarding schools. “Another Brick in the Wall” appears in the film based on the album. In the “Part 2” sequence, children enter a school and march in unison through a meat grinder, becoming “putty-faced” clones, before rioting and burning down the school.
- “Another Brick in the Wall” is a three-part composition on Pink Floyd’s 1979 rock opera The Wall, written by bassist Roger Waters. “Part 2”, a protest song against corporal punishment, and rigid and abusive schooling, features a children’s choir. At the suggestion of producer Bob Ezrin, Pink Floyd added elements of disco.
- Red giant (Wikipedia)
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. The appearance of the red giant is from yellow-white to reddish-orange, including the spectral types K and M, sometimes G, but also class S stars and most carbon stars.
