cholesterol: 胆固醇 chole 'choler' + stereos 'solid' + -ol [chemical compound]
choler: great anger. 胆汁质的人常有精力旺盛、不易疲倦，但易冲动、自制力差、性情急躁、办事粗心等行为表现。多血质、胆汁质、粘液质、抑郁质。
steroid: 类固醇 sterol type of alcohol (from cholesterol) + -oid 酒精=乙醇. 根据羟基所连接碳原子的类型，分为伯醇、仲醇、叔醇。根据分子中所含羟基数目的不同，分为一元醇、二元醇、三元醇，多元醇。简单醇常采用习惯命名法，即在与羟基相连的烃基名称后加个醇字，例如：甲醇、乙醇、丙醇等。又是个需要借助机器之力的领域。问题是做能学习的机器也很难甚至更难？可能通用量子计算才是未来。比如20个变量的逻辑表达式，好像总共有2的2的20次方个函数。左上角计算器可算1024*log(2)/log(10)，算完后别忘了clear.
android: a robot that looks completely human
anthropoid: 类人猿; asteroid: 小行星; tabloid: 小报
thyroid: 甲状腺; from 'shield shaped like a door'

paranoid: 多疑的; para-: beyond
Paranoia is an instinct or thought process which is believed to be heavily influenced by anxiety or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself (i.e. the American colloquial phrase, "Everyone is out to get me"). Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame. 像想的太多
