You can read it for yourself.

This is the correct scientific view of how nature works.

I don't know why you are arguing about Feynman. You reject Einstein and Hawkins and Degrasse Tyson. Why does the fact you reject Feynman too make any difference?

Did you look at Feynman lecture on SR? There is no doubt on his view.

He gave a lecture on Special Relativity that contradicts pretty much everything you have said on this thread. Much of his work was on Special Relativity... the very thing that you have claimed several times on this thread to be "idiocy".

In the beginning of this thread, I understood that you didn't think mathematics or experiment were the way to get the correct scientific view of nature.

Tell me yes or no... is mathematics and experiment the way to get the correct scientific view of nature.

For anyone who cares, here are Feynman's remarks on Cargo Cult science. I think Layman is full of crap when he claims that Special Relativity is an example of Cargo Cult Science...

The correct statement of the laws of physics involves some very unfamiliar ideas which require advanced mathematics for their description. Therefore, one needs a considerable amount of preparatory training even to learn what the words mean..

The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.” But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations—to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess. This imagining process is so difficult that there is a division of labor in physics: there are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess.

This is the key point that I have been trying to make on this thread. If you agree with this, then we are 90% of the way there.

Is necessary to learn the words [but] it is not science...It is not science to know how to change Centigrade to Fahrenheit.

It is not easy to understand energy well enough to use [the word] right. [It displays no understanding to say] "energy makes it move." It would be equally well to say that "God makes it move," or "spirit makes it move," or "movability makes it move."

But also needed is imagination to create from these hints the great generalizations—to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.

The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.”

Part of the advantage of getting a Physics education is that you not only gain tools and a language for scientific investigation (i.e. mathematics), you also get an understanding and experience with the experimental basis for our current knowledge of how Nature works.

Do you understand that LR and SR use the same math (the Lorentz transforms) and are equally confirmed by all relevant experiments?

Do you understand that is not math, nor experiments, nor terminology which distinguishes the two?

I think the educational and psychological studies I mentioned are examples of what I would like to call Cargo Cult Science. In the South Seas there is a Cargo Cult of people. During the war they saw airplanes land with lots of good materials, and they want the same thing to happen now. So they’ve arranged to make things like runways, to put fires along the sides of the runways, to make a wooden hut for a man to sit in, with two wooden pieces on his head like headphones and bars of bamboo sticking out like antennas—he’s the controller—and they wait for the airplanes to land. They’re doing everything right. The form is perfect. It looks exactly the way it looked before. But it doesn’t work. No airplanes land.

So I call these things Cargo Cult Science, because they follow all the apparent precepts and forms of scientific investigation, but they’re missing something essential

Now it behooves me, of course, to tell you what they’re missing. But it would he just about as difficult to explain to the South Sea Islanders how they have to arrange things so that they get some wealth in their system. It is not something simple like telling them how to improve the shapes of the earphones.
