Just a little bit. 😉 I got that. This is what Carl Sagan is good for.

What makes you think that the brain's model is frame dependent? Let's assume for a moment that the brain's model is based on Newtonian mechanics. Then it is frame independent, because Newtonian mechanics is frame independent.

It is a short for "frame of reference", but different frames differ in many ways, not only if they are moving or not. They are different coordinate systems in spacetime. For example, cartesian/ polar/ cylindrical coordinates are different frames in space. Just rotating a cartesian frame makes a new frame. I use the word 'frame' because it is shorter than 'system of coordinates.' If a specific frame is inherent part of a model, this model is frame dependent.

Postulating a Basis for Belief in a Technological Afterlife
I think that your predictions by cherry picked simple extrapolations are, intentionally or not, grossly simplistic for the real world. "It is difficult to make predictions, especially about the future", but I am certain that something very different will actually happen. To @zapatos, you remind an Evangelical preacher. To me, you remind a communist propagandist. Just substitute "classless society" for "human technological advancement" and you get a "hyperhyperdrive" to universal happiness.

Yes, a frame independent value can be measured in a frame. Such a value is 'real'.

I'm sorry, but I don't see a connection. Perhaps we are talking about different things and call them "frames". A frame I'm talking about is for example one that identifies a meeting at 5 pm on the corner of 27th street and 5th avenue. I don't think that frames are real.

"Frames" are coordinate systems. They are arbitrary and there are infinitely many of them. Uncountably infinitely many. They are not models and not interfaces. They are just systems of mapping between some sets of four numbers and events.

Isn't this set frame dependent?
-
Everything is one whole
Me too. So, a "whole" is a collection of events which can be causally related?
-

What is "things"? Do you mean "events"?

In the entanglement, particles do not affect each other.
-
Everything is one whole
I don't see how these examples make everything NOT be one whole. Entangled particles, for example, stay entangled regardless of the distance and without any physical interactions between them. The observable universe stays one whole by the virtue of common history.

Of course, there is. Where in science?

Not so good news for science
Unfortunately, the problem is not limited to a few certain persons. Yes, obviously it is a good thing that these issues are exposed. That's why we need police. Medicine is plagued by untrustworthy clinical trials. How many studies are faked or flawed? (nature.com)

What is especially disturbing to me in this case is the scale. 20 years, president of Stanford, multiple institutions, many people ...

Strange Things
I remember one morning on my way to work in A train shortly before my station a voice of a friend of mine, Alex, suddenly popped in my head. When I got out of the subway, I found myself in the middle of a mess... It was about 9 o'clock on September 11, 2001. The station was WTC. I looked up and saw a huge hole in the upper part of the North Tower. Alex's office was on the 97th floor... I was sure he was dead, and his voice kept playing in my head until I finally got home that day and found Alex's message on my answering machine. He missed his train that day and was late to work. I don't think I would remember about his voice popping in my head if not for these circumstances.

How do you know this? Not necessarily, but it is not a brain function. What do you mean by it? Why does the brain need to recover itself? What do you call "recover" in this context?

Strange Things
I'd hypothesize that "senses" about that person randomly popped into your head thousands of times before and were forgotten because of having no handle to remember them. But this time the memory of the "sense" is accessible because of the dramatic connection to the real-life event.

Neutral simultaneity for two frames.
I am sorry, I don't understand your idea of a relation between these numbers and a triangle or an arc.

Online science forums
For the last two days I've been "studying" recent and ongoing discussions in half a dozen different science forums. They differ to some degree and the choice depends on personal preferences. I'll stick with this one.

How to induce viviparism ? [botany]
Exactly. This is what I do and never have any issues. Grape/ cherry/ snack tomatoes.

Depends on the kind of tomato, perhaps.

Neutral simultaneity for two frames.
I don't know what you mean here, i.e., what should be the same. The body A has velocity v in S, and velocity v'=0 in S'. The body B has velocity u=v/(4-3v2/c2)1/2 in S, and velocity u'=(u-v)/(1-uv/c2) in S'.
