    Elements and operations of the algebra can generally be associated with geometric meaning. The members of the algebra may be decomposed by grade (as in the formalism of differential forms) and the (geometric) product of a vector with a k-vector decomposes into a (k − 1)-vector and a (k + 1)-vector.

    Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

  6. Three utilities problem - Wikipedia

    en.wikipedia.org/wiki/Three_utilities_problem

    The classical mathematical puzzle known as the three utilities problem or sometimes water, gas and electricity asks for non-crossing connections to be drawn between three houses and three utility companies in the plane. When posing it in the early 20th century, Henry Dudeney wrote that it was already an old problem.

  7. Poisson's electrical and magnetical investigations were generalized and extended in 1828 by George Green. Green's treatment is based on the properties of the function already used by Lagrange, Laplace, and Poisson, which represents the sum of all the electric or magnetic charges in the field, divided by their respective distances from some given point: to this function Green gave the name ...

    Schools could design their own profiles, e.g. science, socio-economics, humanities, and technology, or keep a general orientation curriculum. In preparation for the upper-secondary specialization, a ′pre-profiling′ programme in grade 9 has been introduced to help students make their choices in grade 10. [17]

    Math Messages—These are problems, displayed in a manner chosen by the teacher, that students complete before the lesson and then discuss as an opener to the main lesson. Mental Math and Reflexes —These are brief (no longer than 5 min) sessions “…designed to strengthen children's number sense and to review and advance essential basic ...
