Pseudofluid dynamics

SmartMotorist.com The Physics Behind Traffic Jams c2008 “Boredom lead me to fantasize about the traffic being like a flowing liquid, with cars acting as giant water molecules.”

While traffic bears superficial resemblance to fluid currents, attempts to model traffic using fluid dynamics will be mathematically unfruitful as traffic has characteristics opposite to that of fluids. For example, consider that a given current of fluid across a pipe of varying radius will have the highest flow speed across the narrowest segments. For traffic, the reverse applies.

Plonk patsy

The Age It's only plonk if you look at the price tag 2 July 2013 Our grasp of wine’s class and worth is shaky. Several scathing studies suggest we are suckers for mystique, marketing and the price-tag driven power of suggestion.

Lay people aside, numerous studies have demonstrated that even wine experts are unable to distinguish between average and expensive wines in blinded tests.
