Because of the weight of the ends of the forks, and how they’re distributed behind the penny (closer to the glass), the center of gravity of the whole system is actually shifted quite significantly. If I’m right, it would actually have to be right where the penny meets the glass. This mean, in a sense, all the “weight” of the system of the forks and penny is resting right on that point, rather than out in the air, so if you balance it, it’ll be stable on the glass.
The difference between Science and Engineering.
who wrote this? did the doctor write this?
“and then i killed everyone. the end!”
“appendix a: one dalek survived. oops! it’s all good now though.”
“appendix b: haha actually like millions survived but it turns out the time vortex is really good at stopping daleks, who knew?”
“appendix c: also highly effective at stopping daleks: the void.”
“appendix d: there was a minor thing with new york city and the empire state building and some half-human, half-dalek hybrids. that should be the last of them.”
“appendix e: shit they just tried to end reality CLOSE CALL.”
“appendix f: i may have rebooted the entire dalek race. my bad! on the bright side, daleks now come in 7 new flavours!”
“appendix g: daleks just tried to lock me in a box SEE IF I’M MERCIFUL NEXT TIME SOME INNOCENT GIRL GETS CONVERTED INTO A DALEK AND NEEDS MY HELP.”
“appendix h: i met this really cool girl over a radio transmission. we wanted to meet up so i said okay, i’ll beam down to your home in a dalek asylum, and she said okay, i’ll make souffle. she turned out to be a dalek. should’ve swapped pictures first.”
