These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Cthulhu Tech
Artistic License - Physics: Usually explained away by magic or it being an anime genre convention, but sometimes just odd. Perhaps the most glaring example (both due to its short length and because of the way it defies not just science, but basic logic) is the description of electrokinetic weapons:
"With a minimum of moving parts, electrokinetic rail weapons silently fire metallic projectiles at an extremely high and accurate rate with a muzzle velocity that exceeds the speed of sound."
The next paragraph does mention "Beyond the audible crack of breaking the sound barrier, electrokinetic weapons are virtually silent", so it is probable they just didn't want to mention it twice.
