There's also the problem with imperfections in the connection which can lead to rotation as well.
>>
Saying there is actually a force in a rotational frame is kind of like suggesting the Earth is a fixed point that all of the other objects in the universe move around, and there are inexplicable forces that cause them to move. Knowing the Earth is orbiting the Sun and follows its inertial path through curved space-time allows you to model the motion of the planets much more simply, and offers profound insight into the nature of the universe, but it's not strictly necessary. You can create fictional forces to explain the apparent motion of planets as seen by the Earth, and that's exactly what people did.

When you try and make science seem unintuitive, and get views by telling an audience that they are smarter than their high school teachers, you can end up asserting that fictional forces that are necessary to describe the apartment motion of objects in a rotational frame are "real" when that motion and its cause would arise naturally from understanding the object is following an inertial path through curved space-time. In fact, the over-zealous schoolteacher is just trying to make sure you understand that when you look at the stars spin in a circle through the sky, it is the rotation of the Earth you are seeing and not the rotation of the universe around the Earth. One of these views grants insight into the true nature of the universe, and the other does not.

Have you cheated before?

Would you agree that natural scientists are more interested in things that are unexplainable? Wouldn't the main purpose of science be turning unexplainable concepts into explainable ones? The time it takes figuring out something unexplainable is greater in science.
>>
>>15177224
They're usually interested in things that are falsifiable, as in, things capable of being proven false but may be true. That's why you don't get many scientists looking for ghosts and things like that, because while ghosts might exist they also might not so the search could be endless. I think that applies to most things but some things might bend the rules a bit, like finding a theory of everything etc, I'm not sure if that's falsifiable

>while ghosts might exist they also might not so the search could be endless
sorry i should have said: while ghosts might exist it can't be proven they don't so the search could be endless
>>
>>15177224
Yeah for sure, because if we can explain the unexplainable, then we can find cures for diseases and the like.
For example, Koch finding the causative agent for TB eventually led to drugs designed for an acid-fast bacterium

Renormalization seems ok to me. You basically say that charge is actually zero but some interaction is infinitely strong so the net effect is infinite x 0, and this produces some finite number.
In any case its a theory that only describes what is already been measured in an experiment. You can extrapolate and say the trend must be valid out of the range you measured first, but for how long?
One can't just say QED holds at literally any energy.
Also, Feynman didn't invent QED. Just these useless diagrams that allegedly simplify the calculation except you still have to draw dozens ir hundreds of them and who can tell you did it right? I prefer the old way and 10 pages of easy but tedious math are done in a click with a Mathematica program.

STEM-TARDS are literal subhumans. If they got their way the entire universe would literally be nonstop imploding because of their retarded tech-first dogmatism

How good you are at mathematics is directly related to how smart you are. Saying that you don’t like mathematics or have a bad mathematics background is just a cope for being dumb. Mathematics has the most demand on IQ of any STEM subject. Simple as.

>What are the scientific of this?
This is what the Eternal Jew is really worried about, The third largest economic Powerhouse and only with half the population of entire size of USA thank's to bigger brain power.

All Ancient Germanic Tribe bloodlines will be united under one flag, But the language's remain as the are best language's you ear can hear, The best of the best white breeding stock in this world. If we achieve this will be true European Union with Capital In Berlin. With the brain-power we will have be exploring star's and soon leave the rest with their common ancestor from africa. We will dominate the world only with technology that others do not have a true White Man's way of new Atlantis.

That's what you should be working on to give you hope, can you feel it? just like in 1933 again.

exactly 8/11/2023 will be a solid 100 year anniversary since our greatest uncle heroically took to the streets to send the Weimar Globo-Homo a strong signal, We should go to the streets on that date and remove these "rent-free" politicians and make their Over-lord stain their pant's solidly with liquid matter, This indeed will be a strongest bond on earth, if that doesn't happen we'll die out like Brown Apes shit slinging lower denomynators on each other.

Sometimes programming languages have good definitions of math concepts. They tend to be a lot clearer possibly because there's one proper set of documentation written by a handful of experts with community feedback instead of people making up their own definitions strewn throughout thousands of research papers and textbooks over hundreds of years

In JavaScript you can have arrays, maps, sets etc and these are the mathematical equivalent of arrays, maps and sets. They hold numbers (or other things) in various ways and are iterable. All of these come under the generic term of collection. So a map is a type of collection and a set is also a type of collection. In JavaScript they're either keyed or indexed

Get a small cheaper Celestron or something. Or just look at the moon with binoculars. Point a telescope at the area under Orion's belt. And the pleiades are cool. Jupiter is also a good easy target usually it is very bright and you can see the moon's and sometimes even atmospheric bands with a small scope. Saturn is cool too but smaller and depends on its orientation.

>>
>>15176988
Your reference frame is the portals. From that point of view, the cube is moving. Not only that, but it follows a continuous path through the portals. The exit portal being stationary and the cube continuing its path, there is nothing else for it to do but shoot out. Still looks like a hula hoop from the right perspective (the portals) in that sense that anything that goes into a hula hoop necessarily immediately comes out the other end.

in what world?
the portal merely gives the cube more space to move and changes the direction of gravity after it flies through it.
The only possible force that could come from the portal are gravity or electromagnetism emanating from the other side, which now that I think about, could br signifcant for the portal games.
