I'd like to believe in fusion, but it doesn't sound good so far. (On the other hand, there are plenty of recent advances in photovoltaic power systems...) Olber's paradox: I'm getting tired of Olber's paradox. I just wrote up a discussion of it, explaining in detail how hierarchical clustering can solve the problem. It's a bit long to post. If anybody's interested, send me a note including your bitnet address, or, if you aren't on bitnet, your arpanet address. --Geoffrey A.
