… “You must have shown me real loyalty down in the Chamber. Nothing but that could’ve called Fawkes to you.” That’s the very first thing Dumbledore thanks and praises Harry for. Not for rescuing Ginny, or saving the school from the basilisk, or for keeping Voldemort from coming back, but for loyalty.
Dumbledore judges the people he works with based first and foremost on how loyal they are to him. Not because he thinks he’s all that, but because, as I said, he views people as game pieces, and you can’t have your game pieces acting up, can you? He values his pieces. He wants to advance and protect them. But he doesn’t want them running off beyond his sphere of influence and doing their own thing. I think there’s something very ambiguous about Dumbledore’s habit of seeking out desperate, socially outcast people and doing them one or two huge favors that leave them bound to him for life. Remus, Hagrid and Snape all fit that pattern, and Trelawney and Firenze appear to join the ranks in OOP. It kind of makes me wonder what Dumbledore has done for Fletcher, Moody and Shacklebolt.
…The problem with Sirius is, he’s not loyal to Dumbledore at all; he’s loyal to Harry. From Dumbledore’s point of view, it’s as if he’s playing wizard chess, and one of the knights suddenly decides that he doesn’t care what happens to the king, he’s just going to take care of that little pawn on the left. So Dumbledore does the only thing he thinks he can do — he sticks his recalcitrant knight into a safe, isolated corner of the board and keeps him from making any moves. Perfectly sensible and strategically sound, as long as you don’t expect your game pieces to have any pesky emotions or psychological issue that need to be taken into account.
…Dumbledore’s actions at Hogwarts are another symptom of his general approach. He doesn’t treat it just as a school, but also as an instrument in his strategy. People like Snape, Hagrid and Trelawny — all lousy teachers, in very different ways — are given their jobs as perks, because of their past of future usefulness to the Order, and because it strengthens their bonds of loyalty to Dumbledore.
OTOH, look at Lupin, who is a talented teacher. Why wasn’t he hired before Harry’s third year, especially given the difficulty of finding qualified DADA professors? My theory is that Dumbledore didn’t consider it necessary. As far as he knew, Lupin was already totally loyal simply because Dumbledore had allowed him to attend Hogwarts. There was no need to bribe him with a job. He was hired only when his familiarity with Sirius became an important factor. Once Sirius proved not to be a threat, Lupin was allowed to resign…
Designer Eleanor Lutz used high-speed video of five different flying species to create this graphic illustrating the curves swept out in their wingbeats. The curves are constructed from 15 points per wingbeat and are intended more as art than science, but they’re a fantastic visualization of several important concepts in flapping flight. For example, note the directionality of the curves as a whole. If you imagine a vector perpendicular to the wing curves, you’ll notice that the bat, goose, and dragonfly would all have vectors pointing forward and slightly upward. In contrast, the moth and hummingbird would have vectors pointing almost entirely upward. This is because the moth and hummingbird are hovering, so their wing strokes are oriented so that the force produced balances their weight. The bat, goose, and dragonfly are all engaged in forward flight, so the aerodynamic force they generate is directed to counter their weight and to provide thrust. (Image credit: E. Lutz; via io9)
I just want y’all to remember that a few days ago a visibly armed white man was pointing a gun at children in a park in broad daylight. He was calmly talked down and brought in to custody. TJ Lane shot up his school, was taken to trial peacefully, sentenced, escaped, and peacefully…
