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?
20 years ago today, the World Wide Web opened to the public. Today is a significant day in the history of the Internet. On 6 August 1991, exactly twenty years ago, the World Wide Web became publicly available. Its creator, the now internationally known Tim Berners-Lee, posted a short summary of the project on the alt.hypertext newsgroup and gave birth to a new technology which would fundamentally change the world as we knew it.
