I'm currently in the process of producing version 2.0 of the Modern Science Map.
The new version will allow you to hover the mouse over each scientist and reveal a summary panel of information on each scientist as well as being able to click to access the full details from Wikipedia.
I have now uploaded a prototype of version 2.0 here. The hover feature is currently only enabled for a limited number of scientists, mainly on the Physics line between Albert Einstein and James Clerk Maxwell.
Check it out, I was quite pleased with it so far.
Keep checking back, I should have them all down in a few weeks. There's not much on TV at the moment anyway.
