My apologies: The last two paragraphs of my previous post were garbled do to a spurious code. The last two paragraphs of my previous post should read as follows:
More amusing, though, is combining this apparent "trend" in Planck's constant with any trend in the speed of light over the same period. Setterfield claims that although h and c vary with time, their product is strictly constant over time.
Now if we take these data for Planck's constant we find a relative decrease of about 2 parts in 100,000. If the product hc has been constant over this time interval, then we would have expected to observe (since the precision of c-measurements is much greater than this) a relative increase in c of approximately similar magnitude. That is, we should have seen a change in c of about 6 km/sec. We havent. [/code]
