ellipsis - Why is the subject omitted in sentences like "Thought you'd never ask"? - English Language & Usage Stack Exchange
This is due to a phenomenon that occurs in intimate conversational spoken English called "Conversational Deletion". It was discussed and exemplified quite thoroughly in a 1974 PhD dissertation in linguistics at the University of Michigan that I had the honor of directing.

Thrasher, Randolph H. Jr. 1974. Shouldn't Ignore These Strings: A Study of Conversational Deletion, Ph.D. Dissertation, Linguistics, University of Michigan, Ann Arbor

...

"The phenomenon can be viewed as erosion of the beginning of sentences, deleting (some, but not all) articles, dummies, auxiliaries, possessives, conditional if, and [most relevantly for this discussion -jl] subject pronouns. But it only erodes up to a point, and only in some cases.

"Whatever is exposed (in sentence initial position) can be swept away. If erosion of the first element exposes another vulnerable element, this too may be eroded. The process continues until a hard (non-vulnerable) element is encountered." [ibidem p.9]

Applications of computational learning theory in the cognitive sciences - Psychology & Neuroscience Stack Exchange
1. Gold's theorem on the unlearnability in the limit of certain sets of languages, among them context-free ones.

2. Ronald de Wolf's master's thesis on the impossibility to PAC-learn context-free languages.

The first made quiet a stir in the poverty-of-the-stimulus debate, and the second has been unnoticed by cognitive science.

soft question - What are good non-English languages for mathematicians to know? - MathOverflow
I'm with Deane here: I think learning foreign languages is not a very mathematically productive thing to do; of course, there are lots of good reasons to learn foreign languages, but doing mathematics is not one of them. Not only are there few modern mathematics papers written in languages other than English, but the primary other language they are written (French) in is pretty easy to read without actually knowing it.

Even though I've been to France several times, my spoken French mostly consists of "merci," "si vous plait," "d'accord" and some food words; I've still skimmed 100 page long papers in French without a lot of trouble.

If nothing else, think of reading a paper in French as a good opportunity to teach Google Translate some mathematical French.

Vladimir Novakovski's answer to What financial advice would you give to a 21-year-old? - Quora
Learn economics and see that investment and consumption levels (as percentages) depend only marginally on age and existing net worth and mostly on your risk preferences and utility function.

Does left-handedness occur more in certain ethnic groups than others?
Yes. There are some aboriginal tribes in Australia who have about 70% of their population being left-handed. It’s also more than 50% for some South American tribes.

The reason is the same in both cases: a recent past of extreme aggression with other tribes. Left-handedness is caused by recessive genes, but being left-handed is a boost when in hand-to-hand combat with a right-handed guy (who usually has trained extensively with other right-handed guys, as this disposition is genetically dominant so right-handed are majority in most human populations, so lacks experience with a left-handed). Should a particular tribe enter too much war time periods, it’s proportion of left-handeds will naturally rise. As their enemy tribe’s proportion of left-handed people is rising as well, there’s a point at which the natural advantage they get in fighting disipates and can only climb higher should they continuously find new groups to fight with, who are also majority right-handed.

...

So the natural question is: given their advantages in 1-on-1 combat, why doesn’t the percentage grow all the way up to 50% or slightly higher? Because there are COSTS associated with being left-handed, as apparently our neural network is pre-wired towards right-handedness - showing as a reduced life expectancy for lefties. So a mathematical model was proposed to explain their distribution among different societies

THE FIGHTING HYPOTHESIS: STABILITY OF POLYMORPHISM IN HUMAN HANDEDNESS

http://gepv.univ-lille1.fr/downl...

Further, it appears the average left-handedness for humans (~10%) hasn’t changed in thousands of years (judging by the paintings of hands on caves)

Frequency-dependent maintenance of left handedness in humans.

[ed.: Compare with Julius Evola's "left-hand path".]

etymology - What does "no love lost" mean and where does it come from? - English Language & Usage Stack Exchange
Searching Google books, I find that what the phrase originally meant in the 17th and 18th centuries was that "A loves B just as much as B loves A"; the amount of love is balanced, so there is no love lost. In other words, unrequited love was considered to be "lost". This could be used to say they both love each other equally, or they both hate each other equally. The idiom has now come to mean only the second possibility.

--

If two people love each other, then fall out (because of an argument or other reason), then there was love lost between them. But if two people don't care much for each other, then have a falling out, then there really was no love lost between them.

Interestingly, when it was originated in the 1500s, until about 1800, it could indicate either extreme love or extreme hate.
