What if George Bush asked various prominent scientists and intellectuals "What are the pressing scientific issues for the nation and the world, and what is your advice on how I can begin to deal with them?"

Edge posed the question, and published the answers.

Marvin Minsky:

Mr. President:

My idea is that the whole "Homeland Defense" thing is too cost-ineffective to be plausible. The lifetime cost of, for example, preventing each airplane-crash fatality will be the order of $100,000,000—and we could save a thousand times as many lives at the same cost by various simple public-health measures.

Conclusion: what we really need is a "Homeland Arithmetic" reorganization.

Yours truly,

Marvin Minsky
Mathematician and computer scientist

Dear Mr. President,

I think there may have been a terrible mistake. I'm not a scientist.

Worse than that, I'm an actor. So, I don't know how I got recommended to you as a candidate for science advisor. Possibly, someone felt that if we could let an actor be president without major damage beyond a trillion or two, why not science advisor? But, I'm also a writer who has a lifelong interest in science, and I host the PBS program Scientific American Frontiers, and I have played Richard Feynman on the stage, so I can see where the confusion might have arisen.

The commencement speaker at Caltech this past year said,

"We live in a time when massive means of destruction are right here in our hands. We're probably the first species capable of doing this much damage to our planet. We can make the birds stop singing; we can still the fish and make the insects fall from the trees like black rain. And ironically we've been brought here by reason, by rationality. We cannot afford to live in a culture that doesn't use the power in its hands with the kind of rationality that produced it in the first place."

Actually, I was the commencement speaker who said that, but I thought you'd pay more attention if I put the Caltech part first.

The problem is that, although we're all entitled to our beliefs, our culture increasingly holds that science is just another belief. Maybe this is because it's easier to believe something—anything—than not to know.

We don't like uncertainty—so we gravitate back to the last comfortable solution we had, and in this way we elevate belief to the status of fact.
