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. So what are the world's best universities? Well, according to an index by the Times Higher Education, Stanford ranks 3rd in the world. Most people associate Stanford with tech-capital Silicon Valley, which is where the school is located. And in fact, it's largely because of Stanford that the region is now the global capital of entrepreneurship and technology.

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. Soft water, on the other hand, has a low mineral content, either because it has not yet flowed through rocks or wells - like rain water - or because the rocks it has come in contact with have little to no...
