Q: I've been asked to give lectures on electromagnetism in English, but I encounter many problems trying to express mathematical formulas since they are written and I do not know how to read them. Are there any references which elaborate the formulas and express what should we call any mathematical sign?.

A: The following references are useful: Pronunciation Guides for Mathematical Notation, Expressions, and Greek Letters (Reference list) Reading Mathematical Expressions (PDF) How can we speak math? (PDF)

Q: What is the etymology of shithole? Did it originate from A) the orifice through which excrement is passed, or B) the hole in the ground intended for the disposal of such excrement? (This is a serious question for professional research. You don't want to know the details.).

A: The OED's earliest citation for shithole is from the seventeenth century, and it's given as 'coarse slang' for 'the rectum or anus'. The earliest citation for shithole meaning 'a toilet; a latrine' is only from 1947.

Q: There is a saying in Hindi in India 'teri lal' which translates 'yours is red' which means 'Whatever the case may be you are right' as in 'you are always right'. It is a sarcastic way of telling (usually) a know-it-all person (but not meant truly) 'you are right'. Is there an equivalent version of this phrase in English? Example Rohan (the know-it-all): The moon is a sphere John: hmmm Rohan: The moon has its own light. John: OK 'teri lal' (you are right sarcastically).

A:
Though I agree with the others that the sarcasm is usually implied in the tone of the speaker, there is an idiomatic expression which implies a non-committal agreement without sounding overly offensive: whatever you say TFD(idioms): whatever you say I accept what you say, and I'm not going to argue with you. Usually implies that one doesn't really agree with the other person, but is going to do it to avoid a conflict. A: 'Don't worry about the auditors, just run the numbers like I told you.' B: 'OK, whatever you say, boss.' A: 'I told you, my parents let me borrow the car whenever I want.' B: 'Whatever you say.' Farlex Dictionary of Idioms. © 2015 Farlex, Inc, all rights reserved.
