Some Wikipedia articles include sound or video files, which can be played on almost all personal computers. However, your computer must have the right software. If your computer does not automatically play these files when you click on them, downloading and installing free software from the internet can enable it to do so.

Sound files on Wikipedia generally use the Vorbis audio format, and video files use the Theora format, both contained in an Ogg file. These are analogous to other formats used to play digital audio and video such as MP3 and MPEG. However, Microsoft Windows and Mac OS X do not support these formats by default, and require additional software to play them (see below).

Music files may occasionally use the MIDI format (.MID or .MIDI extension). MIDI is generally playable without additional software, as most computers have a MIDI-enabled player and sound card.

For help making and converting video and audio into the format usable on Wikipedia, see Wikipedia:Creation and usage of media files.

Randal Howard "Rand" Paul (born January 7, 1963) is the junior United States Senator for Kentucky. He is a member of the Republican Party. A member of the Tea Party movement, he describes himself as a "constitutional conservative" and a libertarian. He is the son of Republican Congressman and 2012 Republican presidential candidate Ron Paul of Texas and had never previously held political office. Paul first received national attention in 2008 when making political speeches on behalf of his father. Rand Paul is the first United States Senator in history to serve alongside a parent in the United States House of Representatives.

A graduate of the Duke University School of Medicine, Paul has been a practicing ophthalmologist in Bowling Green, Kentucky, since 1993, and established his own clinic in December 2007. In 1994, he founded Kentucky Taxpayers United, of which he is still the chairman.

In 2010, Paul ran as the Republican candidate for the United States Senate seat being vacated by retiring Senator Jim Bunning of Kentucky and defeated Kentucky Attorney General Jack Conway. As a supporter of the Tea Party movement, Paul has been vocal in advocating for term limits, a balanced budget amendment, and the Read the Bills Act, in addition to the widespread reduction of federal spending and taxation. He has gained prominence for his independent positions on many political issues, often clashing with both Republicans and Democrats.
