Last night I saw Dr. Mike Brown at the Kent State Stark speakers series. You may have heard of Brown when he unplaneted Pluto some years ago. I'm the proud owner of a Discovery Store "I Heart Pluto" button, but I have to say, I'm convinced. Pluto ain't no planet.
Don't worry, though, it's still a cartoon dog.
Dr. Brown was also a great speaker. Informative and funny as can be. If you get a chance to see him, I recommend that you take advantage of the opportunity. It's well worth it.
He's also on the interwebs himself.
