According to science without gravity we would be thrown off of the earth. So why are we still here scientifically we should not be standing on this planet but yet we are. Something doesn't add up, can someone help ease my mind with there input.
The Earth is spinning at about a thousand miles per hour. Shouldn't we be thrown from its surface?
Yes I know someone would comment "gravity" but physically we should be thrown from Earths surface. Scientists say that gravity is holding us here but that seems to contradict physics. Maybe someon...
It's not as if I don't regularly see things that shouldnt be there, there

@EmilioPisanty The half-circle contour gives a value which is half of the actual value

I think it is necessary to use the keyhole contour here

I don't know why

Perhaps it is because $(z)^{1/2}=e^{\frac1 2{\ln(|z|)+\arg(z)}}$ repeats itself after $4\pi$ (for same magnitude of $z$) while $\ln(z)$ does it for $2\pi$.
Can someone explain this statement to me: "Can you please explain this statement: "The oxosalts of group 2 metals are less stable to heat than the corresponding group 1 salts because the metals and their hydroxides are less basic than those of group 1?"
Unabke to find satisfactory answer since i) only group trends I can find and ii) Group 2 metal cations should be smaller than there anion counterparts, not larger, thus polarisability arguments don't work
First countable is enough. Let $x\neq y$ be two points in your space that cannot be separated by neighborhoods. Let $O_1,O_2,\ldots$ form a neighborhood base of $x$ and let $U_1,U_2,\ldots$ form a neighborhood base for $y$. Choose a sequence $(z_n)$ such that $z_n\in O_n\cap U_n$ for all $n$. Now...
At the end of the day @SirCumference if your date doesn't realise it's a date at that point, if you just roll with it and enjoy the day as it happens then not only will you know better if you're compatible, but you can then bridge the gap into "hey today / tonight was great, how about we do it again" and throw in bits alluding to it being a date
@Phase Again, this is me being me, but I still don't really get the difference between two people going and doing something together and two people going on a 'date'
@Mithrandir24601 well, not any in the actual day spent but there's a bit in terms of "clear feelings". They could be interested but not in any way more than a friend
It WILL but all subsequent rejections and courage-mustering will be a lot easier
No-one likes rejection but my point is that after the first time, you'll realise how much better it is to be rejected than just letting an opportunity pass and regretting it
Would we really notice the difference if there was a preferred reference frame, in the sense of experiencing observers, experience everything simultaneously on that frame's simultaneity axis?
When I was but a wee lad I had a crush on a girl for years, and felt like I could never tell her about it. It was a shitty few years. Opened up for the first time, got rejected, had a pretty hellish time but after everything was way better
A machine would not notice a difference. As clocks would slow down relative to that preferred reference frame, so would everything within the machine. Only a conscious observer MIGHT experience the difference, should such a preferred reference frame exist and only if the experiencing entity is outside the physical realm
The only time the "date" descriptor really matters is if one person thinks it's a date and the other thinks it isn't (and both think it's a meaningful distinction)
It's really hard to define my previous sentence the way I want it to mean.
Basically as long as you're getting to know each other, or explore possibilities, it's not the worst thing in the world to have a 'date' not be seen the same way by both parties. Just know when to move on romantically / emotionally if they don't become interested / respond positively to yours
@Phase Well, it can get kinda awkward :D Had a lengthy conversation about defining friendship once that started with "You know this isn't date, right?"
I recently had a question which I wasn't sure if this would be the correct site for as it seemed too speculative. But by the time I completed it, it seemed, more concrete than I'd imagined. I would like a second opinion of which site it belongs to before I post it (and delete the other as cross p...
@Phase That's not too bad - I'd say two people are friends if they: enjoy spending time with each other, are able to openly express any feelings/emotions with each other and are willing to go out of their way to help each other is (off the top of my head) a pretty solid basis for a good friendship
@ACuriousMind I just realised how much I hate that notation. why is an electron $-1$ proton number? If it's just a measure of charge instead, why is there no distinction between ions and atoms?
Hm, by contradiction, if a sequence has points in every set of the basis but doesn't converge, there's a neighbourhood $U$ of $p$ such that $\forall n, p_n \nin U$, but $U$ is either the union of two basis element, in which case there's a $p_n$ in it, or the intersection of two, but I'm not sure how to prove it for intersections
