Weird, two Tesla posts in the same week. I just found out that Tesla and Mark Twain were close friends in the late 1800's! How cool is that? I can't believe I didn't know this earlier... Check out the Wikipedia section on his personal life. Also, I found a cool article by Katherine Krumme from 2000 which shows Twains interest in Tesla's invention and their shared theory that weapons of immeasurable power would be a natural deterrent to war (yikes!). Click here to read the pdf.
I love this picture from Tesla's lab, notice how the mad scientist is lurking in the background.
