I'm an Indian student in Ontario, Canada. I want to travel to New York to meet some friends, but I do foresee having to travel to America to attend conferences and maybe do some fieldwork. Am I better off applying for a tourist visa and using it for both purposes?

I suspect that today, this achievement has been granted for the first time to Brazil, with the arresting of Michel Temer, and considering that Lula da Silva is still under arrest. It is normally big news if a former president is incarcerated, so I'd be surprised to know this occurred twice somew...

Suppose I have more than one planeswalker (different planeswalkers) in play. During my turn, am I allowed to use both of their '+' abilities? Or can I only use one planeswalker ability from one planeswalker during my turn?

It is widely attested* that the Su-25 Frogfoot's engines (the Turmansky R-95Sh and later the R-195) were designed to function using a wide variety of fuels, including diesel, gasoline, petrol, kerosene and avgas. For a rough-field front-line attack aircraft, the ability to load it with whatever...

I have somewhere the following sentence: our platform negates the need for a middleman ... but I do not want to offend or upset the middlemen whomever it is ... there are many middlemen in the context I'm reffering to there. The question is how can I replace "negate" that is too abrupt, ra...

For some songs and musical pieces that I am listening to for the first time, why is it that I can occasionally guess what the next note will be? I imagine the next note in my head and sometimes it is exactly correct. I find that this happens more often for slow piano pieces - but occasionally fo...

I would appreciate some help finding $GCD(a^3-3ab^2, b^3-3ba^2)$; $a,b \in \mathbb{Z}$. So far I've got here: if $GCD(a,b)=d$ then $\exists \alpha, \beta$ so that $GCD(\alpha, \beta)=1$ and $\alpha d=a$, $\beta d=b$. Therefore we know that $GCD(a^3-3ab^2, b^3-3ba^2)=d^3 GCD(\alpha^3-3\alpha \be...

I was reading AES algorithm to be used in one of our projects and found that there are exact number of rounds fixed in AES for specific key sizes. 128 bit key size -> 10 rounds 192 bit key size -> 12 rounds 256 bit key size -> 14 rounds Why these specific number of rounds only ?

In a paper I'm writing, there are words using the alphabet ${{\sf D,R}}$. It will be very convenient to add ornated versions as in the picture below, but I have no idea how to create something that is scalable and can be used in text (as opposed to being an included image); hence, no included cod...

I am struggling with how to express the idea that somebody sold out some article of his possession (computer, car, house, etc.) and used the money to buy himself alcohol to drink. For example, -- Where is his computer? -- Well, he squandered it on drink. Dictionaries show that "to squ...

I'm learning Italian (at the beginner level) and the teacher said that it is necessary to use pronouns with the verb "essere" in all cases. For example: Io sono, loro sono, etc. Is it normal to build sentences without it? For example, "Sono italiana" or "Sono a casa".

My first visit to TeX.SX came when I was looking for a symbol for a twisted product: I knew about Detexify and the Comprehensive LaTeX Symbol List, but I could not find the symbol there. I tried the construction that was obvious to me, namely \overset{\scriptstyle \sim}{\times}, but the \sim w...
