This is a blog that takes the name of my magnum opus on scientific philosophy called "The Scientific Worldview." Reviewers have called it “revolutionary,” “exhilarating,” “magnificent,” “fascinating,” and even “a breathtaking synthesis of all understanding.” There is very little math in it, no religion, no politics, no psycho-babble, and no BS. It provides the first outline of the philosophical perspective that will develop during the last half of the Industrial-Social Revolution.

Are there constants in nature?

The Blogger / Google login status, and the ability to post comments, is sensitive to both cookie and script filters. Your readers may need to enable (stop filtering) "third party cookies", in their browser and on their computer. The effects of the newly unavoidable CAPTCHA, and the Google "One account" login, requires third party cookies, even more than before.

Third party cookies filtering, in a browser setting, is the most common solution, overall - but your readers may have to search for other filter(s) that affect their use of Blogger / Google.
Any filters are subject to update, by the creator. If the problem started a few days ago, your readers may have to look on their computers, and find out what product or accessory was updated, a few days ago.

Glenn: "The ends to which Einstein ventured to preserve the hypothesized constancy are well known, starting with aether denial."
ReplyDeletePerhaps I'm uninformed, so can you cite an instance of Einstein "preserving" SOL? In all my reading, Einstein totally agreed that aether had to exist, even if it wasn't "necessary" for transformations.
It wasn't Einstein, but there is a case for variability of the Constant of Aberration. Over decades, the conflicting values were simply consolidated over larger sets of observations and than averaged. It is true that observations ceased when the scientific consensus dictated that SOL was constant, therefore aberration also had to be constant.
Thanks Bill:
ReplyDeleteThe simplest answer to your query about the "ends to which Einstein went" is his claim that time could be dilated. Whenever it became apparent that c, speed of light (your SOL), was not constant, something else had to get the blame.
Being philosophically confused, Einstein changed his mind probably a half dozen times on whether or not aether existed. This statement from his famous speech in 1920 is about the closest he ever got:
"Careful reflection teaches us that special relativity does not compel us to deny ether. We may assume its existence but not ascribe a definite state of motion to it ..." "There is a weighty reason in favour of ether. To deny ether is to ultimately assume that empty space has no physical qualities whatever." (Einstein, 1920)
One reason he became so popular, was his univironmental testing of the waters of social/scientific acceptance. After that 1920 speech, he no doubt got a lot of flack, eventually coming to his aethereal senses with this about-face:
"I believe that I have really found the relationship between gravitation and electricity, assuming that the Miller experiments are based on a fundamental error. Otherwise, the whole relativity theory collapses like a house of cards."
— Albert Einstein, in a letter to Robert Millikan, June 1921 (in Clark, 1971, p. 328)
He had finally figured out that aether denial is essential for relativity. If light was a particle always having a constant velocity, then aether could only get in the way. The indeterministic assumption of finity, with its idealistic perfectly empty space and perfectly solid matter finally had its way.
