BP543 Image depicting infinitely many objects vs. image depicting finitely many objects.
(edit; present; nest [left/right]; search; history)
COMMENTS

Another solution is "evokes infinity vs. not so." Or "seen as having arbitrarily fine detail." All left examples show objects getting smaller and smaller and closer and closer together approaching some limit within the box.

BP545 Solution for this problem (BP545) in English text vs. not.
(edit; present; nest [left/right]; search; history)
COMMENTS

This Problem admits multiple solutions besides "Solution for this problem in English text vs. not so," some of which are listed as the left examples. Some do not depend on the English language, so this Problem is technically "solvable" without the relevant cultural information.

BP548 Due to pixelation, it is ambiguous whether the middle small shape is a resized version of the left shape or the right shape vs. there is a clear choice.
(edit; present; nest [left/right]; search; history)
COMMENTS

A strange Problem relying on pixelation of digital images.

BP551 Unstable balance vs. not

CROSSREFS

Adjacent-numbered pages:
BP546 BP547 BP548 BP549 BP550  *  BP552 BP553 BP554 BP555 BP556

EXAMPLE

The classic example is a pendulum with a solid rod (instead of a string) which has a stable balance point at the bottom of its swing, where if you move the pendulum slightly it will swing back towards that balanced state. However, theoretically the pendulum can also be balanced pointing directly up. In this case, if you move the pendulum slightly it will swing down away from that upwards balanced state.

BP555 Black and white photograph versus drawing.

COMMENTS

Although the images here are related to culture (BP521left), the solution of this Bongard Problem is about the visual style of the images.

BP557 Equal horizontal length vs. not
(edit; present; nest [left/right]; search; history)
COMMENTS

All examples in this Problem are pairs of straight line segments.


This problem communicates the idea of projected distance, in this case from 2D to 1D (x-axis).

BP558 Point sequence that is increasing or decreasing in height vs. point sequence that alternates in height
(edit; present; nest [left/right]; search; history)
COMMENTS

All examples in this Problem are groups of 3 dots.


Any example where 2 adjacent dots have the same height would be ambiguously sorted.

CROSSREFS

Adjacent-numbered pages:
BP553 BP554 BP555 BP556 BP557  *  BP559 BP560 BP561 BP562 BP563

EXAMPLE

Reading from right to left in the first box on the left hand side: the 2nd dot is higher than the 1st, and the 3rd is higher than the 2nd, so the sequence of dots is strictly increasing in height.
