@GabrielDuquette@sarahdoingthing Let me rewrite that "The invariance of a shape under a certain set of motions" quote a few times, OK? -
@GabrielDuquette@sarahdoingthing First, "invariance of X under a certain set of motions" is a long-winded way of saying "symmetry of X". -
@GabrielDuquette “The symmetry of a shape allows us to deduce that two or more measurements must be the same.” -
@GabrielDuquette "The bilateral symmetry of your body tells us that your right arm is as long as your left arm." -
@GabrielDuquette "The rotational symmetry Earth means the distance to the center of the Earth is the same from every point on the surface." -
@St_Rev@GabrielDuquette uh, oblate spheroid? -
@mr_archenemy@GabrielDuquette The previous statement is inaccurate to EXACTLY the same degree Earth fails to be a sphere. - 1 more reply
