So, my last blog entry was about how the idea of 'the weight of the Internet' was a bit mind numbing. If you haven't read that and watched the video, do it now.

Today, I looked at something I heard about a few months ago but admittedly never really explored. It is a collection of more than 2,600 online videos by a guy names Sal Khan; his web site is called KhanAcademy.org. He started doing this for a few family members, and evenutally started sharing them with anyone wanting to see them online, all for free. Many of the videos are done directly by Sal Khan, while others are from third-party sources.

Some advanced local school teachers here in the Bahamas are already using these videos to help their students get introduced to new concepts and subjects, or help lagging students pick up the pace.

But, no matter where you are in life -- student, adult, retired -- I encourage you to start exploring this collection. Even the listing itself is overwhelming, but take the time to scroll through and hit a few that seem interesting to you.

If you want a starting point, check out this video about the scale of the universe.
