Flow Coefficient

(free) This sheet walks kids through how to factor trinomials with no GCF (without guessing and checking!) and also a flowchart that classifies types of polynomial factoring and how to tackle each type.

Liquid Sculptures Highlight the Beauty in Fluid Dynamics

Fluid dynamics is beautiful and complex, with no single, simple equation to govern its dynamic behaviour. The mathematics is monstrous, with scaling factors, coefficients, and exponents customized to each fluid to reflect the quirks of its behaviours. Yet in practice, a single splash is simple beauty.

Boxed Up to Go by Adam Summers, naturalhistorymag.com: Scientists visualized the flow of water around a boxfish by placing neutrally buoyant beads in the water and filming the beads as they swept past plastic models of the fish. The drag coefficient of the boxfish is just 0.2, which is comparable to some streamlined airfoils, and falls well below 1.5, the drag coefficient of a flat-faced box. The edges of the bony box act as keels and passive stabilizers assisting the fish in diving and…

Glittering Metallic Pavilion Morphs Itself As Temperature Changes (Video)

made out of 14,000 pieces of bimetallic material called "thermobimetal" -- usually found in the coils of a house thermostat. This composite metal is made up of two or more layers which have different expansion coefficients. In other words, when the temperature changes, the metals expand at different rates, curling up or down, giving the appearance of a reactive skin
