I had recently watched Air and I couldn't understand what did the little girl and boy mean to show? I searched about it but couldn't find any answer. What are winged beings and why did people kept them in prison? What do the little boy and girl mean?
About the anime version of Air:  Some sources on the net state that Kanna's curses were broken, and her next reincarnation would be a happy one.  Some say that the pair of children playing on the beach were the reincarnations of Misuzu-Kanna / Yukito-Ryūya.  What is the canonical explanation of this ending? Did the curses really get lifted? Please include sources in your answer.
Database Design Best Practices Finding plane equation given two lines Determine an equation of the plane containing the lines $\frac{x-1}{2}=\frac{y+1}{-1}=\frac{z-5}{6}$; $r=\lt1,-1,5\gt+t\lt1,1,-3\gt$.   I calculated the cross product between the directional vector of both lines to find the normal vector $n$, but when I looked for an intersection point $r_0$ to apply the formula: $\lt r-r_0\gt \bullet \ \ n$, I did not find any.  Can I use the point $\lt1,-1,5\gt$ given in the line $r$? Or is it not possible to find an equation of the plane containing two lines that do not intersect? So our 6-month-old boy still doesn't sleep through the night. He still wakes up at least once and wants to eat.  He takes 3 naps during the day, ranging from 30 minutes to 1.5 (sometimes 2) hours.  We usually put him down for the night at least 2 hours after his latest nap, but we haven't been able to get him down to 2 naps per day because he gets pretty cranky during the evenings. Depending on the duration and times of his naps, his bedtime ranges between 10 and midnight.  We have started feeding him a small amount (2 tablespoons dry) of rice cereal after his morning and evening naps in the hopes that he'll have a fuller stomach through the night, but he still wakes up hungry after sleeping between 3 and 6 hours. I can handle the 6 hours, since that means I get 6 hours of pretty much uninterrupted sleep, but it's usually more like 3-4.  Any suggestions? evaluate $\int_{0}^{\infty}\cos(t) t^{z-1}dt=\Gamma(z)\cos(\frac{\pi z}{2})$ How to prove useful property of logarithm of generating functional in QFT? How to prove that $\ln(Z(J))$ generates only? I can't find the proof of this statement, and have only met its demonstrations for case of 2- and 4-point. Is liquid cooling necessary for high CPU performance over extended periods? I'm planning on building a system for high CPU and memory performance.  Graphics performance is not a major concern, as I do not plan to use it for gaming.  I noticed that liquid cooling seems to have become common since my last build, and I am wondering if it is needed in my case.  I do not plan to overclock any of the components.  The intended use for the system is primarily development and occasional compute-intensive tasks that will run on all cores continuously for several days to a week.  The system will not normally be in continuous usage like this, but it needs to be capable of occasional extended periods of continuous use at full capacity.  I have included the main components below.  CPU: i7-5960X  Memory: 64GB DDR4  Graphics card: Nvidia GeForce GT 730 2GB  Drive 1: 1TB SSD  Drive 2: 4TB 7200RPM HDD  Power supply: 700W  Is liquid cooling needed for the above build?  If not, is there any advantage in using it?  I have read reviews that mentioned liquid cooling unit failures that resulted in leaks, so I would rather not use it if it is not necessary.  Thanks! Is it possible to create a URL link to a website on the home screen? In non-relativistic QM, the $\Delta E$ in the time-energy uncertainty principle is the limiting standard deviation of the set of energy measurements of $n$ identically prepared systems as $n$ goes to infinity. What does the $\Delta t$ mean, since $t$ is not even an observable? What happens when a photon hits a beamsplitter? Yesterday I read that we can affect the path and the 'form' (particle or wave) of a photon after the fact ().  Part of what is puzzling me is the beam-splitter. Are the individual photons actually being split into two new photons of lesser energy?  This  implies that you cannot split a photon but it seems that beam splitters do exactly that.

I remember hearing that trees and other plants actually obtain a large amount of their mass from the carbon floating in the air, not the ground beneath them. Does the makeup of air actually contain enough carbon to support this theory, and is a tree's surface area actually large enough to obtain the amount of carbon it needs directly from the air? What would happen if every person in the world gathered at a minimum possible area and jumped all at once? Would that have any effect on Earth? Let $x,y,z>0$ and $x+y+z=1$, then find the least value of ${{x}\over {2-x}}+{{y}\over {2-y}}+{{z}\over {2-z}}$ Let $x,y,z&gt;0$ and $x+y+z=1$, then find the least value of  $${{x}\over {2-x}}+{{y}\over {2-y}}+{{z}\over {2-z}}$$  I tried various ways of rearranging and using AM > GM inequality.

How do I recover my password in Pokemon Go? How to design partitions for SSHD? I'm going to install Linux on Lenovo B5400, which contains:   500GB Hybrid SSHD with a 8 GB SSD and 500 GB HDD   Designing partitions for my 2 Linux distros was quite easy before, when I had only HDD. I always had:   10GB for Linux distro (mounted as "/") 10GB for another distro (again "/"; for another distro; for testing purposes or to assure continuity when switching distros) 2GB for swap (used for both distros; no need to separate) 300GB+ for "/home" (used for both distros; different usernames eliminates possible conflicts)   It's simple, isn't it? I would like to keep this approach, but I know that SSD has its own specificity - it prefers to be read, continuous writing may affect its life span. I don't want to kill SSD in a year, so I would like to move some system partitions to HDD in order to protect SSD. As far as I know /tmp is one of often read&amp;written locations. How much space it needs? What else should be placed on HDD?  Or: how to design partitions to achieve exactly the same effect and to keep SSD as safe as possible?  I'd be grateful for your help. Time Capsule cryptography? Does there exist any cryptographic algorithm which encrypts data in such a way that it can only be decrypted after a certain period of time?  The only idea that I can think of, is something like this: Seed a PRNG with a public value. Run the PRNG for a week and use the final value it produces to encrypt the message. Now anyone who runs that PRNG for a week starting from the seed value you made public can decrypt the message. Obviously this breaks down since they could use more computational power than you; if the time span was years then Moore's Law would apply, etc.  Is there anything like this other than physically burying a private key on a USB stick in a literal time capsule? Why does the order of parameters matter for sp_trace_create?
