I know what imposter syndrome is. But, believe me that's not the case with me. I have worked hard for the 4.5 years of my PhD, but I feel that my research is absolutely mediocre and as a result my self-confidence has taken a toll. Now, my advisor is a brilliant person. She is well known in her f...

What is the highest possible score a player can make in a turn by placing a single tile? Assume language is English, using standard Norh-American rules.

When I'm reading something, I immediately pick up on typos, grammatical errors, misuse of punctuation, and the like, as well as better ways to phrase things. I have no formal education in any sort of writing or English other than GE; my education is in engineering. Is there some way to monetize...

I remembered Ready Player One's dystopian setting, and then wondered what would sports be like in a dystopia? This theoretical dystopia is a world that has been drained of most of its resources, like Ready Player One, except no super-good Virtual Reality like Ready Player One, and all sorts of c...

I have played 630 blitz game at chess.com and only 10.3% of my games are draw; see the diagram. When I play black, my drawing rate is slightly higher than my drawing rate playing white. This is likely because that psychologically I am more content with a draw when I am playing black. I unders...

My opinion is yes, it does, because all useful exposure to the outside world (non-priviledged processor mode) would first require a process running in the outside world. That would require a file system, even a temporary, in-RAM, file system. Another engineer disagrees with me, but I can't seem...

I'm reading through my professor's lecture notes on the multiple linear regression model and at one point he writes the following: $$E[(b-\beta)e']=E[(X'X)^{-1}\epsilon\epsilon'M_{[X]}]. $$ In the above equation, $b$, $\beta$, $e$, and $\epsilon$ are all vectors, $X$ is a regressor matrix and $...

In the Megillah, we read (6:1): בַּלַּיְלָה הַהוּא נָדְדָה שְׁנַת הַמֶּלֶךְ וַיֹּאמֶר לְהָבִיא אֶת־סֵפֶר הַזִּכְרֹנוֹת דִּבְרֵי הַיָּמִים וַיִּהְיוּ נִקְרָאִים לִפְנֵי הַמֶּלֶךְ On that night, the king's sleep was disturbed. He said to bring the book of chronicles, and they read it befor...

I read this around 2015, I think, as a Kindle book. Sadly, I have quite a history of books to work through. The protagonist was a nun, not quite at final vows.

I'm searching for a short story I read a long ago in a different language. It was listed as a story by Ray Bradbury, but I can't find it in his bibliography.

The Sun's rotation period varies from about 25 days at the equator to about 38 days at the poles. As I understand it, this is because the Sun is not solid, and because of the way centripetal force works, the equator must move faster than the poles. Question: if this works, why do Jupiter/Saturn/...

Attended a Purim Seudah tonight at a Sephardic shul where most of the attendees are Israeli. They only made noise during three (maybe four?) times Haman's name was mentioned. I am aware of the teshuva saying "no noise", but can't find anything explaining "sometimes." Is there a soource for this...

Show that the sum$$\sum_{k=0}^{n} {n \choose k}\frac{{(-1)}^k}{n+k+1}$$ is a positive rational number. It is easy to show that it is a rational number. But I am having trouble showing that this expression is positive. It might be some binomial expansion that I could not get.
