1. ## Physics and Intuition

First you will have to explain what YOU mean by "intuition". I consider it a collection of assumptions and preconceptions.
2. ## How long does it take to get good at scrabble games and word recall games?

I'm 77. I'll let you know when it happens.
3. ## String Theory solved

What does it even mean to "solve" a theory?
4. ## Can we remake plastic waste into rocket fuel?

The problem is energy! In order to be useful as fuel, a chemical has to have energy contained in through the way the atoms are put together. Plastic, while made of complicated molecules, doesn't have much energy stored in it.
5. ## An ancient energy source gets a second life to perpetuity.

Have you never heard of "conservation of energy"? The heat energy given off when the atoms recombine cannot be more than the energy required to separate them.
6. ## Earthlings Speak Moon Language

Why would "full moon" and "new moon" be the two "visual states" of the moon? What happened to "waning moon" and "dark of the moon"?
7. ## Why Everything You Do Is Meaningless.

So you are aguing that only things for which you become famous are "meaningful"? Saving a persons life, which no one remembers a hundred years later, is not "meaningful"? What if the persons great great grand child creates a vaccine that cures a disease that was killing people around the world. IF no one remembers that 200 years later, it was not meaningful? That would seem to me to be a very limited definition of "meaningful".
8. ## Ideonomy vs Epistemology

Technically, "ideology" is the study of ideas while "epistemology" is the study of knowledge.
9. ## A relativistic formula

1.678 is NOT the golden ratio. The golden ratio is $\frac{1+ \sqrt{5}}{2}$, an irrational number. Even approximated to three decimal places the golden ratio is 1.618, not 1.678.

11. ## fast prime test?

The only reliable "prime test" of a number, n, is to divide n by every prime number less than or equal to $$\sqrt{x}$$.
12. ## A thought experiment about light

"Going into physics discussions while admitting you have no respect for relativity is like a turkey voting for Christmas." Now that's a good line!
13. ## Why Do Only Cranks Choose To Join This Forums?

In your first post in this thread you said "Why do only cranks decide to join these forums?". My point was that you yourself have joined this forum so you are saying of yourself that you are a crank! Of course, that would mean that I am also a crank but I don't agree with the statement.
14. ## Why Do Only Cranks Choose To Join This Forums?

Thank you so much for the wonderful gift!
15. ## Creating A NFT Of The Work A Alternative To Patenting?

First, work that can be "published" would be "copyrighted", not "patented". But what legal authority would this blockchain have? If you published on a blockchain and someone copied it, would a judge recognize a "blockchain" like he or she would a copyright?
16. ## Why Do Only Cranks Choose To Join This Forums?

Are you admitting that you are a crank?
17. ## On consciousness and choice. A set of axioms

Shakespeare, Much Ado about Nothing, Beatrice to Benedick, "I wonder you keep talking, no one marks you!"
18. ## Chtistoffel notation

What does any of this have to do with the Christoffel Symbols?
19. ## German's relationship with English usage.

It is not a matter of whether anyone here speaks German. The original post was in English and not responding in English is rude.
20. ## A thought experiment about light

Okay, that is true but has nothing to do with inertia.
21. ## A thought experiment about light

First, in your "pinball" experiment, you would also need the pinball not affected by gravity or be air resistance. I am not sure what is meant by "not affected by inertia" Light does not, strictly speaking, have mass but it does have energy which, by "E= mc^2", is equivalent to energy so light HAS inertia.

23. ## Is The Universe Mathematical? Revisiting My Small Number Hypothesis

It isn't the "universe" that is mathematical, it is people who are mathematical and impose numbers on their vision of the universe.
24. ## Time Travel: Jesus Being Sent to Die On A Cross, Unethical

From what do you "understand" that??
25. ## Jesus Dying On The Cross Allowed Sin

There is a difference between "believing in Christ" and "saying you believe in Christ"! Christians (I am not a Christian myself) assert that if you really believe in Christ you can not avoid venal sins but would not commit mortal sins.
