Dr. Stephen Hawking and Dr. Brian Marsden
On Sunday - March 24th, 2002 - our guests were Dr. Stephen Hawking, the world renowned physicist, and Dr. Brian Marsden, the Director of the Minor Planet Center at the Harvard Smithsonian Astrophysical Observatory.
Dr. Brian Marsden has long been a central figure in the study of asteroids and comets. For many years he has been the director of the Minor Planet Center and as such has been responsible for verifying newly discovered asteroids and comets as well as keeping track of the asteroids and comets that have already been discovered. If anyone has a question about an asteroid or comet, the Minor Planet Center was the place they went to for accurate information. Whenever a question arose about the possibility of an asteroid hitting the Earth, the Minor Planet Center was where people called. And when you realize just what a small staff works at the Minor Planet Center, then you know that for many years the name Brian Marsden has been synonymous with the Minor Planet Center.
Dr. Marsden's work has focused on calculating the orbits of asteroids and comets - i.e. where are they now, where were they in the past and where will they be in the future. Not only is this a task that is 'computationally intense' but when you realize that there are now something like 30,000 known asteroids and comets, you can imagine the size of the job.

Because of the nature of his work, Dr. Marsden was one of the 'early adapters' of electronic computers. In fact, his work with asteroid orbits reaches back to a time when a computer was the person doing the computations, not the machine used for the computations.
Although I have long known about Dr. Marsden and his work, it was only fairly recently that I had the chance to sit down and chat with him. He was an absolute delight. He is wonderfully entertaining, has a wealth of wonderful stories and is an absolutely charming individual. He is truly a gentleman and a scholar. It was a great pleasure getting to spend time with him and hear his stories about the early days of computing along with getting to learn more about asteroids and comets from a man who has spent his whole life studying these objects.
It was a special pleasure getting to interview Brian and an even more special pleasure being able to bring that interview to you.

Dr. Stephen Hawking is certainly well known to anyone with an interest in the research that is happening at the frontier of human knowledge. Dr. Hawking is the Lusasian Professor of Mathematics at Cambridge University. {This is the same position once held by Sir Issac Newton.} His research into the nature of space and time have changed our fundamental ideas about how the universe operates and he is widely acclaimed to be one of the most most brilliant scientists of the 20th and 21st centuries. He is well known to the general public as the author of several notable science books including A Brief History of Time and his current book, The Universe in a Nutshell.
Dr. Hawking routinely works with mathematics that most of us can only stare at in awe and confusion. And yet he does this by holding the equations in his head, because he contracted ALS almost thirty years ago.
|
Today Dr. Hawking's body is restricted to a wheel chair and he can only speak by using an artificial voice connected to a computer which he laboriously accesses using the two fingers of one hand which are the only parts of his body that he can still move. And yet his mind roams the most distant realms imaginable. His researches show us subtle truths about how the world works and demonstrate that there are few things people cannot achieve.
It was a special pleasure on March 15th to be able to attend a lecture at CalTech and listen to Dr. Hawking tell us about new research that shows that the universe we live in may be just a sliver of a vaster universe, that there may be other 'realities' than our own and that these theories about other universes may be testable in the laboratory. It was awe inspiring to listen to him as his computer-generated voice took our imaginations to the limits of our universe and beyond.
So it is my special pleasure to bring you a brief excerpt from that lecture through the kind permission of Dr. Hawking and CalTech. {Please note that this audio excerpt from that lecture is copyright by Dr. Stephen Hawking and should not be reproduced or redistributed without getting his written permission.} You can learn more about his recent research by reading his newest book, The Universe in a Nutshell, which is available in hard cover from Bantam Books and also as an unabridged audio book from Random House Audio. This book, along with Dr. Hawking's earlier books, are all highly recommended. Read them and prepare to have the limits of you mind stretched farther than you thought possible.
The Space Frontier Foundation sponsors The Watch, a privately funded project that supports various observational, research, and public outreach activities aimed at dealing with the problem of asteroid impacts. There are many ways that you can get involved with this activity.
Click on the image above to learn more about The Watch.
Note : If you are a subscriber to the Hour 25 Newsletter and have been using "excite@home" you will need to send me an email at [email protected] with your new address. Be sure to include your old email address so I can properly update the newsletter mailing list. And if you're not on the mailing list, now would be a good time to sign up.
Important Note : Be sure to update your anti-virus software. There are some new viruses going around that are particularly nasty and sneaky about how they propagate. {One of these nasty bits propagates by sending itself to people as a reply to existing emails in your in-box.} I got attacked by this virus while working on the current edition of Hour 25, and though my anti-virus software stopped it cold, it did cause me to lose some time. I use Norton's Anti-virus software and I'm quite satisfied with it. {Like I said, it stopped this new virus in its tracks.} But do make sure you're using anti-virus software and that you keep your virus definitions up to date.

Dan Simmons
On Sunday - March 17th, 2002 - our guest was Dan Simmons. We talked with him about his newest book A Winter Haunting and also found out where he got all those great stories that he worked into Darwin's Blade. Along the way we chated with him about the art and craft of writing and learned a bit about how this master craftsman plies his trade.
It was a special pleasure to interview Dan a couple of weeks ago when he was in town on tour for his newest book, "A Winter Haunting". On the one hand I was glad to have another chance to interview Dan because I knew from past interviews that he's always interesting and has great insight into the creative process of writing. On the other hand, I was glad to have this chance to interview him because the last time he was in town we had some scheduling problems and were unable to get together for an interview. And on the gripping hand, Dan's newest book is really great and I was looking forward to hearing him tell us more about it.
Dan is one of those rare authors who can easily move between genres without his books losing that essence that marks them as his very own. His style is easily recognizable for its focused word choices, powerful images and complex yet believable characters who come alive as you read the story.

A Winter Haunting was a special pleasure to read. It takes the characters and situations from Dan's earlier book Summer of Night and moves the story forward forty years. Where before we saw the characters as young boys, in this newest book the focal character, Dale Stewart, is now a man well into the challenges of middle age. These books are tied together, as Dan says, like the sides of a Moebius strip, with each one affecting how you view the other. Taken individually, each book is a delight, but when viewed together they weave a complex web that sparkles in your mind's eye long after you finish the books.
A Winter Haunting is hard to describe - it weaves together elements of supernatural horror, psychological suspense, character study and mystery - but let it just be said that this book is highly recommended.

Howard V. Hendrix
On Sunday - March 10th, 2002 - our guest was Howard V. Hendrix. Last week David Brin referred to Howard as one of the up and coming writers to keep an eye on. With this interview you'll get acquainted with Howard and discover why I enthusiastically agree with David's comment.
Until recently Howard has been a full-time Professor of Literature and a part-time writer. Now he's a full-time writer and a part-time Professor. His students' loss is the gain of readers everywhere.
Although Howard does not have a background in the hard sciences, that does not stop him from doing his homework and writing books that show what happens when a highly inventive imagination is grounded in the realities of science and technology. Howard does not claim to write hard sf or fantasy or whatever label you want to apply to his books. He says that he writes "Howard Hendrix Fiction"®. Well whatever you call it, I enjoy his writing and look forward with great anticipation to his next book.

Please note; in tonight's interview Howard and I talk at length about many subjects, including politics. But some things just never seem to come up, such as the September 11 terrorist attacks on America or the war in Afganistan. The reason for this surprising omission is that we did this interview before the events of 9/11. So consider this interview to be a time capsule from before the day the world changed. I know Howard will be back in town sometime in the future and at that time we'll have another of our free ranging talks on those subjects and more. I can't wait. Till then, go read his books. I think you'll like them. I know I did.

David Brin
On Sunday - March 3rd, 2002 - our guest was David Brin. He was in LA about a week ago to do a signing for his newest book Kiln People. We met at the office of his brother's publishing company to do the interview and whilst surrounded by decades worth of publishing history, we chatted about his books and the future. It was lots of fun.
Science Fiction has been described as the literature for those people who enjoy recreational thinking. I couldn't agree more. Within the framework of science fiction we have the ability to consider questions about why our world is the way it is. We can imagine how differences in physics would lead to different forms of life or we can postulate changes in historical events and speculate about how today's world would be different. By taking this 'anything goes as long as everything is internally consistent' view we get new eyes for looking at our world and gain fresh insights into our civilization and history. And we also get some ripping good yarns to entertain us.
David Brin is one of the best practitioners of this 'anything goes...' type of Science Fiction. And to judge by his ever growing collection of awards, I conclude that I am not the only person who feels this way.
Dave's newest book Kiln People continues his tradition of outrageous ideas and well-told stories. I mean, what can I say about a world where people can create fully-functional copies of themselves made out of clay, send them out to do any sort of work and then at the end of the day download the memories from that duplicate so that they know everything that it learned and remember everything it experienced?
In the hands of a lesser writer this book would have been called Golem World and it would have been pure fantasy. Entertaining perhaps, but not Science Fiction. But in the hands of a master like Dave Brin, this book becomes a great example of Hard-SF speculation that tickles your thinking bone and challenges you to imagine all the implications of its one - admittedly big - 'what if' premise. This book was lots of fun and is highly recommended. {And it didn't hurt that Dave never missed an opportunity to slip in a wicked pun or three.}
