I am an Indian citizen with valid German student long term resident visa. Can I travel to India and come back through Paris airport? Is there a chance of being denied to board? Prices are cheaper from Paris than from a german airport.  Edit: Sorry that my English is not clear. Yes, I meant I plan to travel to Paris by train and take Paris-Mumbai flight and return to Paris via Mumbai-Paris return flight and come back to Germany via train.
I found many related questions on this site but I am still not sure about the rules. How can I decide if I need a visa to transit?

How do I beat Uprising on Legendary difficulty? The achievement "Distinguished Service" requires that you beat Uprising on the regular gamemode on Legendary difficulty.  This means we can't pick our usual huge DPS heroes like Bastion and Orisa, and are stuck with Torbjorn, Reinhardt, Mercy, and Tracer.  The phases are as follows:   Hack all 3 terminals Defend the Payload until it's ready Escort the Payload until the gate Destroy all 4 Orisas.   So I ask this after having failed Uprising on Legendary dozens of times.   How do I beat Uprising on all 4 phases?   Specifically asking for the latter 3 phases.    Defending the payload is hard when it gets to the Bastions that drop in because Reinhardt's shield gets melted very quickly and Torbjorn has little to no DPS.  Tracer must be relied on but it seems there is no way to stop the perfect aim of Bastion as strafing around does nothing.  If and when we actually do manage to defend it, we're stuck on escorting, which is even harder thanks to the tank mode Bastions.  And finally, even if we do make it to the final fight, which has only happened once, the fight is so tough that even if we slowly inch ourselves closer to the end we run out of time.  The previous question I asked was different because Uprising (All Heroes) allows you to pick any 4 heroes to form your squad, but the original gamemode will not let you pick. Also, the achievement requires you to play the original mode -- Uprising (All Heroes) on Legendary does not reward players with the achievement. Book recommendations for fluid dynamics self-study I have my bachelors degree in engineering science: computer science, option electrotechnic. I have a good understanding of basic mechanics and dynamics, calculus (differential equations).  The books I'm now having a look at are:       What book do you recommend for studying fluid dynamics on my own and why? How to show that every Boolean ring is commutative? Schengen visa refusal on threat to public policy, security, health I applied for German Schengen visa as a medical escort to my relative in a different country from  where I reside, but my visa application was refused and the refusal letter  was written in German as the following:        Ein oder mehrere Mitgliedstaaten sind der Auffassung, dass Sie eine Gefahr für die öffentliche Ordnung, die innere Sicherheit, die   öffentliche Gesundheit gemäß Artikel 2 Absatz 19 der Verordnung (EG)   Nr 562/2006 (Schengener Grenzkodex) oder die internationalen   Beziehungen eines oder mehrerer Mitgliedstaaten darstellen.      I was in Germany for nearly a year with my relative during his treatment; I extended my stay there 3 times; and I returned back home two months ago in order to renew my passport. I applied again using the same documents that I used for my extension in Germany.    First, can anyone tell me what the refusal means? Next, is there any possibility that there is a mistake in the assessment?    Note: In English this reason is...     One or more member state(s) consider you to be a threat to public   policy, internal security, public health as defined in Article 2(19)   of Regulation (EC) No 562/2006 (Schengen Borders Code) or the   international relations of one or more of the member states).

What focal length lens do I need for photographing the moon? I would like to know whether it is possible to photograph moon without any flaws with a canon EOS 550d..

What does this mean exactly?  What causes veiling glare, and how can it be avoided? How does it relate to those floating polygonal lens flares one often sees in movies? A set of elements in a reduced unity ring Let $(A,+,\cdot)$ be a unity ring with the property that if $x \in A$ and $x^2=0$ then $x=0$. Consider the set $M=\{a\in A | a^3=a\}$. Prove that:      a) $2a\in Z(A)$, $\forall a\in M$, where $Z(A)$ denotes the centre of the ring $A$;   b) $ab=ba$, $\forall a,b\in M$.   My attempts revolved around the fact that an idempotent element in a reduced ring is central. So, since for $a\in M$ we have that $(a^2)^2=a^2$, it follows that $a^2\in Z(A)$, $\forall a\in M$. The next thing I wanted to use in order to solve a) was that $Z(A)$ is a subring of $A$, so if I had proved that $(a+1)^2 \in Z(A)$, $\forall a\in M$, then we would have reached the desired conclusion. However, I couldn't prove this and I honestly doubt that it is true. Another idea that I had was to prove that $M$ is a subring of $A$. Of course, this didn't work out because I cannot even prove that $M$ is closed under addition. Again, I don't know if this is true and it most likely isn't. As for b), I think that a) should be of use, but I don't know how. It is a well-known problem that a ring with $x^3=x$ for any $x$ in that ring is commutative, but since $(M,+,\cdot)$ is almost definitely not a ring, this doesn't help. EDIT: Is there any chance that this question is simply wrong? I tended to believe this before asking it here too, but since nobody has made any progress on it until now I am even more inclined to think so. What is the formula for $\frac{1}{1\cdot 2}+\frac{1}{2\cdot 3}+\frac{1}{3\cdot 4}+\cdots +\frac{1}{n(n+1)}$ How can I find the formula for the following equation?  $$\frac{1}{1\cdot 2}+\frac{1}{2\cdot 3}+\frac{1}{3\cdot 4}+\cdots +\frac{1}{n(n+1)}$$  More importantly, how would you approach finding the formula? I have found that every time, the denominator number seems to go up by $n+2$, but that's about as far as I have been able to get:  $\frac12 + \frac16 + \frac1{12} + \frac1{20} + \frac1{30}...$ the denominator increases by $4,6,8,10,12,\ldots$ etc.  So how should I approach finding the formula?

KernelEvents::REQUEST is not fired on cached pages Date(time) ranges using `datetime2` I'm trying to do some scenes which use a mixture of 3D backgrounds with 2D animated characters.The best way I've figured this out so far is to use a plane with an image sequence of pngs which hold the frames.  The problem with this method is Blender seams to only load image sequences based on image numbering. If I wanted to do a sequence which loops say, frames 0-5, then repeats 4-0 for the 'return' of the animation, I would have to load frames doubled up.  Is there a way, maybe with a script, to change the sequence order? I can see it as a useful plugin but my python skills are pretty much non existent.
