Said it before and I'll say it again: just because you understand the magic doesn't make it any less magical. A wizard may know the ins and outs of their spells, but they're still spells. Our entire universal is fucking magical, we just happen to have a decent understanding of why (some) of it functions the way it does. Jiggle a quark here and another may jiggle the same way somewhere in the vicinity of Betelgeuse, that's fucking wild and magical and incredible, and just because we have some level of understanding behind the mechanics doesn't make it not magic. It just makes it a hard magic system.
