2. Pattern Blocks - Wikipedia

   en.wikipedia.org/wiki/Pattern_blocks

   Pattern blocks were developed, along with a Teacher's Guide to their use, [1] at the Education Development Center in Newton, Massachusetts as part of the Elementary Science Study (ESS) project. [5] The first Trial Edition of the Teacher's Guide states: "Work on Pattern Blocks was begun by Edward Prenowitz in 1963.

3. Polynomial decomposition - Wikipedia

   en.wikipedia.org/wiki/Polynomial_decomposition

   the roots of this irreducible polynomial can be calculated as [5] 1 ± 2 1 / 6 , 1 ± − 1 ± 3 i 2 1 / 3 . {\displaystyle 1\pm 2^{1/6},1\pm {\frac {\sqrt {-1\pm {\sqrt {3}}i}}{2^{1/3}}}.} Even in the case of quartic polynomials , where there is an explicit formula for the roots, solving using the decomposition often gives a simpler form.

4. Golomb ruler - Wikipedia

   en.wikipedia.org/wiki/Golomb_ruler

   There is no requirement that a Golomb ruler be able to measure all distances up to its length, but if it does, it is called a perfect Golomb ruler. It has been proved that no perfect Golomb ruler exists for five or more marks. [3] A Golomb ruler is optimal if no shorter Golomb ruler of the same order exists. Creating Golomb rulers is easy, but ...

5. Scale ruler - Wikipedia

   en.wikipedia.org/wiki/Scale_ruler

   A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale. In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.

6. Sparse ruler - Wikipedia

   en.wikipedia.org/wiki/Sparse_ruler

   A Golomb ruler is a sparse ruler that requires all of the differences be distinct. In general, a Golomb ruler with m {\displaystyle m} marks will be considerably longer than an optimal sparse ruler with m {\displaystyle m} marks, since m ( m − 1 ) / 2 {\displaystyle m(m-1)/2} is a lower bound for the length of a Golomb ruler.

9. Graduation (scale) - Wikipedia

   en.wikipedia.org/wiki/Graduation_(scale)

   A ruler with two linear scales: the metric and imperial.It includes shorter minor graduations and longer major graduations. A graduation is a marking used to indicate points on a visual scale, which can be present on a container, a measuring device, or the axes of a line plot, usually one of many along a line or curve, each in the form of short line segments perpendicular to the line or curve.
