I swear, they talk in this series so much, and explanations for everything seem so long-winded... I wonder if it's a translation thing or the original also felt that way (maybe it shouldn't surprise me, it's an adaptation of a novel :P)
...
In short, editing good.
A hallmark of immature authors is excessive verbosity. The value of a good editor in helping them reign in their word burn rate and spend words more wisely cannot be overstated. (Unless, apparently, your name rhymes with "Wavid Deber".)
as a physicist, I am incredibly bothered, that shes trial and erroring her way to creating things like a flying broom. I mean safety concernc aside, if you arent especially lucky, no way you could fine tune something to fly. (and to be fair, she still seems to have problems.) Yes, yes, I know, experimental physics are and will always be important, no doubt, but I guess what Im trying to say is: for having knowledge and thought process of the 21st century, shes suprisngly unsystematic.
I get where you're coming from. I honestly sympathise with you a lot because I've been in the same boat. Here's the problem: she's not a scientist.
From the outset she is, at best, an enthusiastic dilettante engineer. Stuff like rigour and developing a body of theory through scientific methods are not what she does. She's a mostly-empirical heuristic integration machine running at full tilt with naught but a shaky internalisation of kid-friendly simplifications of natural laws drilled into her head by an education system that doesn't work.
The bitch of it is, that's normal. It's painfully normal. Maybe you and I first internalised the idea of developing a falsifiable hypothesis through the standard compulsory education curriculum of wherever we grew up. But you'd probably be shocked and dismayed that most people really don't learn the things they're taught in school.
They memorise by rote.
And then they forget.
(This is part of why Kamachi Kazuma's work is such a clusterfuck.)
Anyway, considering the mean, I think she's honestly doing pretty well. She probably won't be the Richard Arkwright of this world's magindustrial revolution, but she might just be the Leonardo da Vinci of its magical Rennaissance.
(Admittedly, If I were writing this, I'd probably get off in the weeds about how she has to invent precision. :P)
