2. Dimensional analysis - Wikipedia

   en.wikipedia.org/wiki/Dimensional_analysis

   A simple application of dimensional analysis to mathematics is in computing the form of the volume of an n-ball (the solid ball in n dimensions), or the area of its surface, the n-sphere: being an n-dimensional figure, the volume scales as x n, while the surface area, being (n − 1)-dimensional, scales as x n−1.

3. Fermi problem - Wikipedia

   en.wikipedia.org/wiki/Fermi_problem

   A Fermi problem (or Fermi quiz, Fermi question, Fermi estimate), also known as an order-of-magnitude problem (or order-of-magnitude estimate, order estimation), is an estimation problem in physics or engineering education, designed to teach dimensional analysis or approximation of extreme scientific calculations.

4. Elementary mathematics - Wikipedia

   en.wikipedia.org/wiki/Elementary_mathematics

   Elementary mathematics, also known as primary or secondary school mathematics, is the study of mathematics topics that are commonly taught at the primary or secondary school levels around the world. It includes a wide range of mathematical concepts and skills, including number sense , algebra , geometry , measurement , and data analysis .

5. Six-dimensional space - Wikipedia

   en.wikipedia.org/wiki/Six-dimensional_space

   One example is the surface of the 6-sphere, S 6. This is the set of all points in seven-dimensional space (Euclidean) R 7 {\displaystyle \mathbb {R} ^{7}} that are a fixed distance from the origin. This constraint reduces the number of coordinates needed to describe a point on the 6-sphere by one, so it has six dimensions.

7. Buckingham π theorem - Wikipedia

   en.wikipedia.org/wiki/Buckingham_π_theorem

   An example of dimensional analysis can be found for the case of the mechanics of a thin, solid and parallel-sided rotating disc. There are five variables involved which reduce to two non-dimensional groups. The relationship between these can be determined by numerical experiment using, for example, the finite element method.
