What Are The Best Universities In The World?

Harvard and Yale are often referred to as “the best of the best”. But when it comes to the highest ranked universities, these and other Ivy League schools don't even make it into the top five.

Water becomes ‘hard' when it has a higher than normal concentration of minerals, primarily calcium and magnesium. Water picks up these minerals from rocks and soil as it flows through rivers, wells or other waterways.
