the letter that got to mean angle, and death, and brainwaves, and still votes no on everything
means the eighth letter of the Greek alphabet (Θ, θ), borrowed by mathematicians and scientists as a go-to symbol for angles, unknown variables, and brain-wave frequencies.
from From Greek θῆτα (thēta), itself descended from a Phoenician letter, teth, meaning roughly 'wheel' — the round shape is right there in the letter's body. The 'votes no' reputation comes from a real ancient habit: Greek jurors cast a theta, short for thanatos (death), to condemn someone, while an alpha or other mark meant acquittal — so the letter picked up a grim shorthand for 'no' and 'death' long before it ever showed up in a physics equation.
