Imagine a planet that's identical in pretty much every aspect (including Homo Sapiens) to our own current Earth, with only a single exception - the continental crust has, for whatever reason, much less iron in it. What's in the core/mantle is not all that important, as long as it provides the con...

My Yardman MTD riding mower has a deck with a belt that's engaged only when I want to start cutting grass. The deck belt loops around a number of pulleys, and sometimes slips when I go too quickly in long grass, or at a regular speed through thick grass. When the belt slips, the blades slow down ...

I have seen the following in several papers: $1_{\lvert r\rvert>1}$. What does this mean? Does this evaluate to 1 if $\lvert r\rvert>1$ and 0 otherwise? What would this evaluate to if instead of 1 we had a variable like $x$? Thanks.

I'm practicing algorithms, and I just can not come up with a faster solution to this problem, but I'm not hitting the benchmark. The problem is: in a large list of large integers, I must find the one element, that is present in odd numbers. E.g. [1,1,1,1, 2,2, 3,3,3, 4,4,4,4]. I wrote several sol...

Noob here! I captured video of myself writing on my ipad- pure white background with pure black text.

When translating named entities (for example, a person name), phonetical translation (known as transliteration) is used to make Katakana characters sound like its roman characters equivalent.

Im 19F & I'm starting my Computer Science course this year. Before starting it, I wanted to make sure I had good GCSE & A level Maths knowledge.

I'll give an example for my first question: $x^2 + x + 1 = 0$ Clearly $x = 0$ and $x = 1$ aren't solutions, so first we can safely divide by $x$: $x + 1 + 1/x = 0$ By subtracting $1/x$ from both sides we get: $x + 1 = -1/x$ By plugging the value $x + 1$ back we get: $x^2 - 1/x = 0$ Multiplying by...

It is conventional to number the three persons of Latin and Greek and many other languages so that the first person is the speaker, the second one is the listener, and the third one is anyone else. Did the ancient grammarians already have this numbering? If yes, was it an explicit numbering (firs...

I have been answering questions on Math S.E as well as Physics S.E. Today I was pointed out for using \mathrm instead of using \sin by a fellow user. So my question stands that, which of them is more visually appropriate for a reader and more acceptable: 1. $\sin t$ 2. $\mathrm{sin}\ t$ as repre...

This question comes from Spivak Calculus Chapter 1. How can we algebraically solve $|x − 1|+|x − 2| > 1?$ I know that if we 2 absolute values and no constants, we can square both sides, but I'm pretty sure this is not the case here. My attempt was to split this into different sections: $|x − 1|+|...

I've started cycling recently and am clocking decent mileage now. The only problem is, the bike is very old and weighs just shy of 20 KG, it's a heavy one! It also has Kenda Kinetics tyres, I think they are made mainly for off road so not the fastest. My main goal with cycling is to cycle 40 mi...

I vaguely remember a book I read probably more than 5 years ago. For some reason I think the author is a famous female fantasy/sf author (but I am not 100% sure) The story follows the main protagonist and we often see things from his perspective : it is about a bum who is a very "paranoid" magici...

If not, are there any restrictions that would need to be imposed to ensure that the values of the two samples would be identical? I apologize in advance if this is such a basic question.

I'm toying with the idea for a world where instead of minting coins out of valuable metals all countries us mana, the 'fuel' of magic, as a currency itself. Since mana always has value, in it's ability to be used to cast valuable spells, and is highly portable and exchangeable it turns out to be...

Let $p(x)=x^4+x+1$ be a polynomial in $\mathbb{R}[x]$. How can I prove that $p$ doesn't have real roots? My attempt: From calculus, I know that $$\lim_{x \to \pm\infty} p(x) = \infty$$ Then, if it has real roots we have two or four real roots. I know that if $$\gcd \left( p(x), p'(x) \right) = 1...

I read recently that a red dwarf star might actually look white. I realize there's a wide range in red dwarf surface temperature, 2,500 to 3,500 degrees K, compared to 5,778 for our Sun. Metal at 2,500 degrees K is nearly white hot with just traces of yellow. Is that true for 93% hydrogen 7...
