Stoichiometry is the process of balancing chemical equations, and subscripts in chemical formulas play in important role. Chemistry students use subscripts to calculate the number of moles (a measurement of the amount of a substance) of each element on each side of the equation.
As The World Wide Web Turns 20, Take A Look At The World's First Website. The World Wide Web turned 20 years old on Tuesday. On April 30, 1993, the Web went public for everyone to use (for free) and two decades late CERN, the organization that brought us the Web, has brought the first website back to life at its original address. It's hard to believe that it was only 20 years ago that a website looked like this: Because nobody understood the Web yet, the site had a page called What's out there? that explained how to use the Web. (Much hard without the search engines or social networks of 2013.) How did people find what they were looking for?
The World Wide Web is the collection of linked pages that are accessed using the Internet and a web browser. English physicist Sir Tim Berners-Lee is regarded as having invented the World Wide Web in 1989. Since then he has continued the development of web standards and other web related projects.
