Details: When John, decided to renovate his garage, he also wanted to attach it to his house. The only one wall that was available to achieve this was the kitchen wall. The contractor informed him that the area of his new garage will be limited by the cost of the materials he should buy. After some calculations, they decided
Social networks, email and cyberchat have added to the lexicon of English through "coining," blends, clips and replacement. Does this show the development of a pidgin or simply fashionable slang? Is written communication doomed to ever shorter shortcuts, at the expense of expression, or is the technology "additive" in nature, bu

. Well, here we are again with that English Channel, which appears to have repeated significance in flying firsts. Louis Bleriot, French aviator and inventor, was the first individual to successfully cross the English Channel in a motorized aircraft. On July 25, 1909, he flew his aircraft, called the Bleriot XI, a three cyli

All boulders and rocks (large enough not to be buffeted by air current) appear to take the same time to hit bottom. My conjecture, observes Galileo, leader of the team, is that there is a universal gravitational constant which affects all objects, large or small. Knowing, as he does, that if such a constant exists, call it g for

Why is it important to understand linear equations in business? In particular can you provide examples where the relationship between items that can be affected by management and 'items' that management wished to achieve or attain may be 'linear'. Can you think of items for which the relationship in NOT linear?
