http://www.maplesoft.com/applications/view.aspx?SID=154129&ref=Feed
Venturi flowmeters use the height of a liquid column to measure the pressure drop (and hence the flowrate) of fluid in a pipe. However, small errors in reading the height of the column will affect the calculated value of the flowrate.
<BR><BR>
Methane (at 1 bar and 40°C) enters a venturi meter with a water manometer (with a measurement error of ±1 mm). The upstream pipe area is 0.05 m2 and the venturi throat diameter is 0.025 m2.
<BR><BR>
The water displacement across the manometer is 3 cm. Given the measurement error, this application calculates the potential range of flowrates.

This application is an educational activity modeling the current system of U. S. Presidential Elections. It is set up in the form of a game in which each player manages a candidate from one of the United States' two major parties. Eight turns simulate an eight week long campaign, with players' decisions affecting the standings of their candidates in state-by-state polls. After the campaign is complete, these polls are used to simulated elections within each state and the District of Columbia and a winner is determined according to the Electoral College results.

http://www.maplesoft.com/applications/view.aspx?SID=154100&ref=Feed
In 1935, Einstein, Podolsky and Rosen published a paper revealing a counter-intuitive situation in quantum mechanics which was later known as the EPR paradox. The phenomenon involved an entangled state., which Schrodinger called "not one but the characteristic trait of quantum mechanics." In textbooks, entanglement is often presented in abstract notations. In popular accounts of quantum mechanics, entanglement is sometimes portrayed as a mystery or even distorted in a nearly pseudoscientific fashion. In this worksheet, we use Maple's LinearAlgebra package to represent quantum states and measurements in matrix form. The famous Bell's inequality and teleportation can be understood using elementary matrix operations.<img src="/view.aspx?si=154100/8df7b465a1583cedab7e3e6452644591.gif" alt="Matrix Representation of Quantum Entangled States: Understanding Bell's Inequality and Teleportation" align="left"/>In 1935, Einstein, Podolsky and Rosen published a paper revealing a counter-intuitive situation in quantum mechanics which was later known as the EPR paradox.

If an object is subjected to several forces having different magnitudes and act in different directions, how can determine the magnitude and direction of the resultant total force on the object? Forces are vectors and should be added according to the definition of the vector sum. Engineering dealing with many quantities that have both magnitude and direction and can be expressed and analyzed as vectors.
