Radiant (meteor shower) Radiant (meteor shower) The radiant or apparent radiant of a meteor shower is the celestial point in the sky from which (from the point of view of a terrestrial observer) the paths of meteors appear to originate. The Perseids, for example, are meteors which appear to come from a point within the constellation of Perseus. Meteor paths appear at random locations in the sky, but the apparent paths of two or more meteors from the same shower will converge at the radiant. The radiant is the vanishing point of the meteor paths, which are parallel lines in three-dimensional space, as
Morris–Putnam point Morris–Putnam point The Morris–Putnam point (MPP or “Profit Horizon” ) is the point within a break even analysis where an algorithmic trend line indicates break even will be exceeded by n percent. Economists and Financial analysts use the Morris–Putnam point to predict the impact of commodities costs on juice and heavy metals profits. Meteorologists use "The Point" to forecast dew points and localized wind gusts. Sales people use the point to rationalize the addition of ‘fees’ to previously agreed upon prices because when modeled skillfully, the Morris–Putnam point almost always predicts future success. For example, if a citrus farm produces
