- Both of you are wrong in assuming there was some inductive, experiment-based
- process for obtaining the special theory of relativity. It is still a matter
- of dispute as to whether Einstein knew of the Michelson+Morley experiment
- (his auto-bio suggests not, but some letters suggest maybe), but it is clear
- he did not base his theory on this observation. He based his theory on the
- question "what would light look like if I was traveling along side a light
- beam at the speed of light?" and the different answers he looked at.
-
- Einstein, like many theorists, did not trust experiments because they
- contain uncertainties and errors and their results change from time to
- time. We do not have to look any further than the "Oops-Leon" particle
- that anticipated (to be polite) the discovery of the Upsilon, or the
- history of Polywater to find cases where data proved to be the results
- of experiments, and nothing more.

- Umm, the experiments must show that they _do_ occur in metal lattices in such
- a way that no protons or gamma rays are released either. I do not think any
- experiment has been done with sufficient controls to establish such a fact.
- There are claims of helium accompanying heat, but the amount of helium is not
- equal to that required to explain the heat, and the same experimenter sees
- heat without helium under other conditions. Not very convincing.
-
- Numbers matter. If I need a nuclear reaction releasing 20 TeV to the lattice
- for every helium, the solution is in the laboratory, not some theory. If I
- need to find a source for 20 eV per helium, it could be atomic in origin
- and helium is being undercounted.
