I present to you a #Newtonian #gravity #physics #simulator that can simulate gravity for up to 30 bodies and their rings... a result of my farting around with #Claude, who loves doing the UI rendering/shading code and coordinate transformations that I hate doing. It's not serious #science or #astronomy, nor is it novel. It's just #hacking with #python, but it's been #fun. #opensource https://gitlab.com/opalmirror/stellar-gravity-simulator

Right - so 2 basic ways to look at it:
Each specialty branch comes up with their own perspectives, priorities/hierarchies, and jargon. With few exceptions, they stay in their own lanes and do not mix outside their field/subfield. Their writings are stand-alone, rarely intended to connect back to the greater human knowledge base. They'll tell you exactly what "wet" or "sound" is, based entirely on their tiny-desk world-view.
The other way would be a general model of vibration, perhaps based on quantitative info rather than qualitative. It would incorporate all modes of vibratory phenomena, regardless of mediums, velocities, or other characteristics that were fleshed out by some subfield as critical for their particular context & definitions.
Frequency (Hz) actually would be a good quantitative baseline for this, if it hadn't been exorcised from #quantum mechanics.
The "old QM", as espoused by the founders and historic supporters for the split in Physics, used a semi-classical approach that was later abandoned. Later, Pi was added to E = hf as convenience for some aspects, but frequency generally falls away when you work with quantum states ala Schrödinger. #Time is just an input to QM, and is the #Newtonian, absolute kind. The concepts of frequency & wavelength seem to get in the way of the probabilistic formalism.
IMO, the #probabilistic formalism then gets in the way of a #relativistic completion to quantum theory being developed, though in reality, there is no limit to the imaginative supplemental mathematic epicycles that can be added while still spitting out the same expected answers.

My rather standard 6 inch Newtonian telescope produced terrible spikes on bright objects, especially Mars.I replaced the 3 vane spider (secondary mount) with this curved secondary and it eliminated spikes produced by bright targets.

I modified the secondary holder on my 6 inch #Newtonian to have a 180 degree curve, and now it doesn't have spikes around bright stars. Of course, the bigger the telescope, the more difficult that is to do. And if the main mirror is a segmented mirror, forget it and enjoy the spikes. -
@copsewood That's true, but my story involves humans. I wasn't talking about relativistic effects or infinite acceleration. I assume limits on acceleration, i.e. drive force, and limits on compensating for the effect of acceleration. Just making the point that if the pursuer is going at 4 G and the pursued is accelerating at 3 G, the pursued with a head start is still going to pull away for a while. Acceleration is not the same as speed. That's why I hashtaggd #Newtonian mechanics.
-
#Newtonian mechanics: So even though the pursuing ship has a faster drive, the head start of the pursued ship means it is pulling away from its pursuer. It will take several minutes for the faster ship to start closing the gap. Relative velocity and acceleration are two different things. This can add some tension to a #spaceChase #amWritingSF

FIY Should update within 24h https://youtu.be/RIGkmqzJdfQ
It’s a #foss 6dof racing game with a #Newtonian flight model similar to #EliteDangerous.
It does have a #Linux version but the world gen lib is single threaded on Linux so Proton may be a better choice for now.
It also features access to full ship telemetry and head tracking including OpenTrack via UDP thanks to my nagging 🤪
No idea about VR. Apparently it works but I can’t test that.
-
I only have old (but decent) #telescope gear. I have a decently mounted 6 inch f/5 #Newtonian for example. The mount is a motor driven but manually controlled #EQ.
From what I'm seeing, to get to a point to get digital photos through an #AutoTrackingMount, I'd need a new electronically controlled mount, an #autoguider, and a #DigitalCamera capable of time exposures. Right?
That would easily cost 2k or more from what I see.
Am I seeing this right?

#Kant always had a deep appreciation of the time reversable world of #Newtonian physics. The notion of the sky played backwards or the earth going backwards is a gorgeous mindfall – one can go a long way down, thinking of that. Myself, last night, I merely bumped into the door. I hit my nose. However, I read once – in #HeinzPagels wonderful The Cosmic Code – an explanation of the Newtonian universe that has since haunted me.

I am a bit disappointed when I witness this type of bullying, and it's not just people that have nothing to offer in the way of a #free_market or lacking a brand for themselves that engage in such #dogpiling.
Trying to define what the Fediverse is in terms of social acceptability is an exercise in futility at best, and in the extreme, it is hate stemming from #envy or projection by those afflicted with self-loathing.
The Fediverse is a #censorship_resistant communications network - go forth in #commerce, go forth in hate, go forth in sharing your backyard barbeques with the family and friends, or promoting your creativity - sharing your printings, photography, electronic project gizmos; these are all #brands, things that define what you care about, and what you are about. It's not a bad thing. It's s good thing, usually.
It is a place where so-called #Big_Tech and #mega_corporations can #participate - but they cannot dominate - it is antithetical to their desire and ambitions of #dominion over the #marketplace.
When your #brand is about capability, personality, product or services that you derive an income or admirer stream from, that is #positivity.
When you pile upon others for having a #dream or #vocation, and denegrate those with s vision for themselves and their talents, that too, is part of your brand - if this is you, then your brand is that of a hater.
It can be frustrating for people entering a social space to feel free enough to #share aspects of themselves with strangers, especially when you're just trying to find your bearings and #navigate that space, and coming face to face with negative personalities that enjoy belittling others. But those people really are quite the vocal minority.
There have always been list bullies, #trolls, and general malcontents in every corner of the online world. That's not going to change. Certain types of mediums seem to exacerbate the extent of their influence, like mediums where only short, hit and run messaging is the constraint.
Short messaging platforms can be ideal for pushing out a quick synopsis of your thoughts and ideas, but there's no reason why you should seek to be constrained by the lack of a platform ability to enable more comprehensive coverage of anything you have to share, market, sell, or produce, because in the #Fediverse, there are many platforms to choose from, and almost all of them afford you with the same ability to communicate your messages, creations, and ideas across the entirety of this space.
In the article below, written by a student endowed with a wealth of said positivity, I suggest reading it while replacing nouns like #Faceplant, #Twatter, #YouTube, and #InstaSPAM with nouns such as, #Friendica, #Pleroma (or mastodon), #PeerTube, and #Pixelfed, respectively; since those are some of the close corollaries we currently enjoy here in the Fediverse, remembering that anything you publish on any of those platforms can be shared and propagated natively across the entire Fediverse - and of course, far beyond.
For the creative types of you out here, say, your thing is selling personalized Converse All-stars with custom paint jobs, it's important to realize that your actual reach when you post far exceeds that which any deprecated, legacy silo systems have the potential for, because that post with the photo of your latest set of "Chucks" crosses the boundaries of one type of social networking platform - it's like if you publish a short video at YouTube and it automatically shows up on InstaSPAM and Twatter, without ever having to make a separate post, or posting a product of your latest commissioned painting (part of your brand) on InstaSPAM and suddenly, everyone following you on #Soapbox, mastodon, #Misskey, and Friendica servers sees it too.
Such is the breadth and reach of publishing anything about you, yourself in the Fediverse - worldwide, in the global feeds of everyone else's Fediverse accounts... And we're only growing, as we continue to retire those old deprecated, legacy silo systems.
Ah, but what about all those #meanies, lambasting you for "breaking the rules" and marketing your image and product brands?
News flash! There are no such fucking rules - only imaginary restrictions envisioned by some people with small-minded, defeatest, insecurity issues, and misery loves company. Those haters and self-loathing unfortunates would like nothing more than to instill such negativity in you, perhaps for personal, or even political reasons.
If you let those worthless, insignificant, but very loud and vocal sorts dictate your happiness and success in any endeavor you choose, whether to simply make friends around the world or marketing whatever it is that you do best and are passionate about, then it might be best if you just unplug your computer, trade in your #Android for a flip-phone, and get a job at the local smelting plant (no offense to steel workers), never again dreaming or aspiring to harness the infinite power of your imagination.
So what to do about these curmudgeon-like trolls and list #bullies that have always been a part of the online, let alone everyday life landscape? The same thing you do in every other situation in your life - ignore, mute, and block them - unceremoniously, without acknowledgement or response. These sad excuses for people have no power whatsoever except that which you grant them, and the Fediverse arms you with the #tools to #filter out their voices entirely.
This doesn't mean that you necessarily disappear from their timelines and feeds. You probably won't, but just as it is when you go to your local ☕ coffee house or grocery store, workplace, or enter your classroom, you filter them out of "your" existence, and suddenly... They cease to exist.
I recently published an article in response to one such dogpiling and so-called, "cancelling" event. Those self-hating projectionists actually believed that by propagating a campaign of negative publicity against another creative newcomer's brand - in this case, Raspberry Pi, they could achieve 'cancellation' of that company and its product line here in the Fediverse. Fat chance.
These semi-organized malcontents actually even published a blog article (linked to in my aforementioned article), documenting their success in destroying that brand, along with it's employees and product line.
The reality however, is much different, in fact quite the opposite affect was evidenced, sort of a #Newtonian "equal and opposite reaction" #physics principle.
These children went so far as to demand from Fediverse server administrators what you may occasionally see hashtagged as #Fediblock - a block of other users and instances at the server level by any Fediverse server admin that will listen, or can be brow beaten into submission... But rarely does anyone pay that sort of nonsense any mind at all. Such measures are reserved for people and instances that most average, everyday folks find offensive - like militant leftist sites, personalities, or kiddie pr0n pedophiles and others cut from the same cloth.
At best, when haters like them folk claim to wage battles against those regular people and #communities that they despise, issuing calls for the ominous sounding "defederate them!", the only thing they actually achieve is "self-cancellation", by virtue of painting themselves into a corner when they "defederate" themselves, and that is usually followed by many of their registered users leaving that instance - in this case, everybody loves Raspberry Pi computers, which you can buy for under fifty bucks.
What did the good folks at Rasberry Pi do to deserve such ineffectual wrath from these hateful sad sacks? Only two things:
First, the company rep, responding to one of these agitators stated the obvious, more or less saying, 'If you don't like us then feel free to unfollow us', and when that resulted in a rather ascerbic retort from the professional hater, the Rasberry Pi spokesperson committed the cardinal sin of simply #blocking the troll.
That's it. No biggy, poof! You're gone. Nothing is worse to these maladjusted losers than being unceremoniously ignored with the forever button. It is comical, but it is also sad. One's mission in life should not be to make others as sad as they themselves are.
Don't let anyone belittle or condescend you. The worst (best) they can do is remove themselves and others like them from your timeline feeds, where you don't actually care to see them anyway - so it's win-win 👍
So just know, your going to hear from your fair share of bullies, trolls, and other types that derive a sick and twisted pleasure from harming others - but this is about you, your products, services, brand, and your happy life in the real 🌎 world.
It is a simple matter to ignore, dismiss, disappear them, and move on - millions of good people, other brands, and customers or new friends want to meet and greet to know you!

I hope that helps! And have a wonderful time in the Fediverse!

It is #citogenesis! The book that Wikipedia cites just has one line: "She [Sor Juana] was also a student of scientific thought and experiment, and corresponded with English scientist Isaac Newton."
And in its sources, it lists Wikipedia!
Whatever, in my headcanon #SorJuana was a physicist of #Newtonian calibre.
