BP933

Ball will reach edge of bounding box under gravity vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Strictly this Problem's solution is not actually about gravity, it is about a constant downwards force (the ball's time-independent path does not depend on the magnitude of the force, only direction). The phrasing for the solution is a shorthand that takes advantage of human physical intuition.`

Reversible transformations vs. non-reversible transformations.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`All examples depict a process that transforms one object into another (two example input-output pairs are provided in every panel). In left-sorted examples, each input corresponds to a unique output, whereas in right-sorted examples, different inputs could potentially lead to the same output. There is a sense in which all the processes described on the right "lose" some amount of the input's information.`

(edit; present; nest [left/right]; search; history)
