I got really excited recently when I learned about John Grisham's new book. And no I'm not a Grisham fan. But his new book means a lot to me because it's about something called "focused ultrasound," an extension of an idea I had many many years ago. I was never able to convince anyone it was viable. And I didn't have the resources to pursue it, but I always hoped someone would eventually figure it out -- and someone actually did. Finally. Grisham decided it was important enough to write a book about, and his book is free -- because he wants the news to be as widely disseminated as possible. It's a huge medical breakthrough, and I'm really proud of myself, because I had that basic concept in mind so long ago.
