- In a continuing effort to teach Jed about the proper workings of science
- I will respond to his question as to whether I consider Yamaguchi's
- results "invalid".
-
- Stripped down to the basics, Yamaguchi's experiment involves two observations
- that are correlated: a rise in sample temperature and a change in the
- peak shape and amplitude for an RGA scan for nominally mass 4 ions. I
- have no basis for doubting that these observations have been made just
- as reported. Let us agree to call these observations "valid". These
- observations do not, however, constitute a scientific result.
- Yamaguchi must make an interpretation of these observations which he
- then puts forward as a scientific result. I disagree with his
- interpretation, for reasons I have stated at length in my earlier
- message, and therefore suggest that his experimental results are
- not valid as evidence for a cold fusion process.
-
- Interestingly Yamaguchi's observations themselves contain a potential
- for being selfcontradictory if one were to attempt to extend the
- interpretation of the observations into a proposed model for the
- fusion process. Because samples containing hydrogen show the same
- temperature rise as those containing deuterium, simple logic says
- that either the temperature rise is not related to a nuclear reaction
- process, or the change in the mass 4 peak is not a significant indication
- of the process, or there are two different processes producing the heat
- and only one produces results in a distortion of the mass 4 ion peak.
-
- and only one of the processes results in a mass 4 ion peak.
