Before Einstein, it was believed that science was just all about compact summaries and experience during research. When Einstein arrives on the scene, his theory of relativity was able to open new paths towards complicated mathematical equations that other scientists didn't know about. This opened up tons of opportunities that shaped up science and how we calculate various mathematical problems that can be used in various aspects of the world.
<span>In a free market economy the price of different products gives information about the demand and supply of the products. The price of products increases when the demand rises as there are more buyers willing to pay a larger amount for the same product. Price also goes up when the number of producers supply a smaller amount of the product as they are in a position to demand a larger amount for the same product.
