It is First Principles based, and supported by coders and physicists (International even...) I don't think anything I have seen here over the years can compete. The processing power requirements alone exceed anything realistic folks here have access to for any kind of a timely output on a run. This...

Wait, by top minds do you mean top physicists or top coders?

big difference...

You will have to wait. Sorry. I can share that the coding effort was collaborative between some of the top minds in the field. There is nothing else like it right now. It is the cutting edge for plasma sims. :) and proprietary. Then I bet it uses my distributed dynamic octree idea for massive scala...

Another thing to consider is that a rocket's velocity at a given altitude is optimized for maximum fuel efficiency, considering the air pressure and thus friction. Basically it goes as fast as it can so long as that's below terminal velocity. The available thrust-to-weight ratio can then be taken in...

if we compare BFR to traditional airline, all things being equal, the primary costs per passenger are fuel and maintenance. if we set maintenance equal, we're down to fuel costs. and now one can see that BFR saves fuel over an airline by going to a higher altitude and thus less air friction. however...

also similar are the fast-multipole method https://en.wikipedia.org/wiki/Fast_multipole_method and a variation i wrote based on oct-trees ( https://en.wikipedia.org/wiki/Octree ) with dynamic depth. https://sourceforge.net/projects/octreemethodforparticles/ they all attempt to reduce the o(n x n) al...

Yes, I would say it is the most advanced 3D particle plasma sim out there. Part of the work has been to create the software. It runs on a multi-cell super computer. The outputs are impressive (and pretty). Explain to me the algorithm, please? Is it an all-pairs method? If so, does it use fast multi...

i give up. you guys are beyond all hope.

this has nothing to do with conservation of energy. try reuminating on the pieces of the phrase: "energy" and "conserve". what does "energy" mean? what does "conserve" mean? what does putting these two words together mean? take your time... now hold that thought, and see if you can answer this ques...

Conservation of energy in this cases is simple: - when gas, treated in bulk or as individual particles, descends a potential well it gains energy. Thus air at ground level is naturally warmer than air at altitude. Introduce gas dynamics and we get a natural adiabatic lapse rate between altitude/pre...

We apparently can't have a rational debate with a religious zealot, especially when he's in denial about his beliefs being a religion, and his authority being high priests. Happyjack, study up on basic thermodynamics, with an emphasis on adiabatic lapse rate and how that relates to convection. When...

The only argument I have yet seen from Happy Jack is that we must believe in Global Warming because his high priests and prophets tell us so. Strange then, that I don't recall making that argument even once! On the contrary, I've found myself constantly repeating the importance of data and evidence...

Happyjack, Diogenes is saying that you're citing religious texts. And I agree with him on that. Exactly right. I figured the more intelligent among us would get it immediately. "Global Warming" is a religious cult that pretends to be scientific. They use science Jargon and they pretend to use scien...

hanelyp & Diogenes:

here's an excerpt from karl popper's "conjectures and refutations", read out loud: https://www.youtube.com/watch?v=ztmvtKLuR7I

Happyjack, Diogenes is saying that you're citing religious texts. And I agree with him on that. i don't recall citing any religious texts. can you show me where i did? i've been citing scientific studies well-backed by research and evidence. All which are reproducible and falsifiable. To better und...
