I feel impelled to comment on Mike Alder's "While the Newtonian insistence on ensuring that any statement is testable by observation (or has logical consequences which are so testable) undoubtedly cuts out the crap, it also seems to cut out almost everything else as well. Newton's Laser Sword should therefore be used very cautiously.”
First, please don't panic! This article is about pseudoscience and those who practice it, and does not require knowledge of mathematics.
I just wanted to make a comment on the clipping from the Christchurch Star concerning "nuclear extinction" which appeared on p.9 of the NZ Skeptic periodical. In the clipping, a refutation of this possibility was based on some writings of one Bruce Cathie who is claimed therein to be a mathematician among other things.
