The Navier-Stokes equation for an incompressible viscous fluid. The Navier-Stokes equations have wide applications such as weather modelling. One of the millennium prize problems stated by the Clay Mathematics Institute is the Navier-Stokes existence and smoothness problem concerning the mathematical properties of the Navier-Stokes equations which currently remain unsolved.

Long Division Error Analysis

Engage your students with 9 Error Analysis worksheets for long division. My students LOVE error analysis, and I have even seen kids take error analyses out to recess because they are determined the figure out what error took place, or the perfect wording to describe what happened.


Leonhard Euler (15 April 1707 – 18 September 1783) was a pioneering Swiss mathematician and physicist. He made important discoveries in fields as diverse as infinitesimal calculus and graph theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also renowned for his work in mechanics, fluid dynamics, optics, and astronomy.


Chaos Theory: A mathematical concept that explains that it is possible to get random results from normal equations. The main precept behind this theory is the underlying notion of small occurrences significantly affecting the outcomes of seemingly unrelated events.


Sir William Thomson, lord Kelvin (1824-1907) was a Scottish engineer and physicist who was instrumental in the success of the electric telegraph which ensured his fame and fortune. He also did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics. He proposed the scale named after him in 1848 and now it is mainly used in physics in conjunction with Celsius.
