The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.

The line edge roughness in block copolymer patterns is strongly dependent on the interface tension between the two phases, which in turn, depends on the Flory "chi" (χ) parameter. [74] A higher value of χ is preferred for reduced roughness; the interfacial width between domains is equal to 2a(6χ) −1/2 , where a is the statistical polymer ...

Tricky Towers is a physics-based tower building game puzzle video game that uses a form of the block-stacking problem as the central game mechanic. [2] It was released on digital distribution service Steam for Windows, OS X, and Linux, and for the PlayStation Plus service in August 2016, before being released on PlayStation 4 a month later.
Design patterns in computer science represent abstract solutions to common software design problems. While they are not abstractions in the same sense as data structures or mathematical concepts, design patterns provide a high-level language for software developers to communicate and implement solutions in a consistent and recognizable way.
The block design test is also a relatively accurate measure of spatial ability and spatial visualization ability used in daily life. [6] The block design test is considered one of the best measures of spatial ability, although it is subject to certain problems of administration, such as anxiety or over-cautious responding.
A partially balanced incomplete block design with n associate classes (PBIBD(n)) is a block design based on a v-set X with b blocks each of size k and with each element appearing in r blocks, such that there is an association scheme with n classes defined on X where, if elements x and y are ith associates, 1 ≤ i ≤ n, then they are together ...
