Wave interference is the phenomenon which occurs when two waves meet while traveling along the same medium. If two crests meet up with one another the resultant net effect is of enhanced crest. This interference is known as constructive interference. If a crest and a trough meet up with one another the two pulses will try to cancel each other's effect and the resultant net effect will tend toward zero or the equilibrium position. This interference is known as destructive interference. Ever wondered why carpenters saw the wood in the directions of the grains rather than up against the grains? - The bundles are sliced clearly leaving a smooth surface with minimum defects.

Economics of health diets
Submitted by bizthinker on April 26, 2006 - 11:58am. commodities | diet | dieting | economics | fitness | Health | investors | money | slim | tradeDeveloped nations are fighting a worldwide epidemic against obesity. As the Economist(April,2006 edition) notes, about 50% of kids in England could be obese by 2020. The percentage of Americans with BMI over 25 grew to 62 around 2003 and has reached a plateau since.
When such numbers hit a 'tipping point' they drive a mass consumer shift towards health diets. People become inundated with reports that highlight the dangers of being overweight and as a result health diets, fitness centers, and weight loss scams start having a field day. Advertisers that specialize in demonizing the McDonalds of the world sprout out of nowhere with strident rhetoric against unhealthy eating.
