Pluto was considered for a long time the ninth planet of our Solar System. However, that changed on 2006, when the International Astronomical Union (IAU) decided to reclassify Pluto in the new category named “dwarf planets” changing the landscape of or Solar System as we knew it. But, what were the reasons that made astronomers reconsider our Solar System distribution? And why was just Pluto affected?

The World Wide Web beginning and early years

On August 6, 1991 Tim Berners-Lee, a computer scientist, wrote in a newsgroup: 

 The WWW Project merges the techniques of information retrieval and hypertext to make an easy but powerful global information system…The project started with the philosophy that much academic information should be freely available to anyone…

This date is known as the birth of the World Wide Web.

The World Wide Web, WWW, or Web is a model that specifies how to share and access information over the Internet. The first steps to becoming the web a reality had taken place in 1980 when Tim Berners-Lee, a graduated in Physics from Queen’s College at Oxford University, started working as Independent Contractor at CERN(European Organization for Nuclear Research). During that time, projects’ information was stored and updated in different computers, and sharing information was difficult because of the differences in hardware, operating systems and software. To solve that issue and improve the way of organizing and sharing the information Berners-Lee built Enquire, an hypertext based software that allowed users create, edit and extract information. Enquire was the predecessor of Web.
