If you have an older web browser, please update it to Microsoft Internet Explorer
version 7.0 or greater (recommended). Without this browser our site cannot
be viewed the way it was meant to be viewed. You may also experience trouble viewing
the streaming videos.
Windows Media Player version 10 or greater is also highly recomended to view the
streaming videos. If you have a player that is not Microsoft Media Player or an
older version, you may not be able to view the streaming videos.
Finally, the PHD web site also includes some Flash animations. You will need to
install Flash to view these animations.
