"Final" state of the N-Body-Problem demo of my FOSS Entity-Component System, https://fennecs.tech 🦊💫

#GameDev #3BodyProblem #ScreenshotSunday #GodotEngine #Csharp

glowy simulations of 2, 3, 4, and 5 star systems, stylized in a demo for a game Engine. The title reads "N-BODY PROBLEM", and there's a logo of a fox stylized as a lightning bolt in the center. An FPS counter reads values at around 500 fps for 100 parallel simulations. A larger block of text reads: This demo showcases the power of fennecs Entity-Entity relations in solving a common ECS challenge: managing N:N relationships efficiently. The renowned 3-Body-Problem demonstrates that even slight variations in initial conditions can lead to dramatically different and chaotic outcomes in systems with three or more interacting bodies. With fennecs, multiple Entities can interact with each other seamlessly, enabling complex behaviors such as flocking, leader-following, and grouping by spheres of influence. The framework achieves this while maintaining good cache coherence, memory locality, and optimal iteration order. Each colored cluster represents a small, self-contained clique where 2, 3, 4, or 5 stars (Entities) have relationships with all other Entities within the same group, forming a distinct Archetype. All simulations coexist harmoniously and interactions are driven by the same runner passed to a single Query, ensuring each Entity is processed exactly once for each other Entity it interacts with. The two other Queries then simply integrate the calculated forces into movement and position.

I’m watching #3bodyproblem and reading EE Doc Smith’s Skylark at the same time. And the similarities are striking, even if the timescales are a less realistic in the century old books. #scifi #bookstodon @bookstodon

Wie viel Wissenschaft steckt in der Netflix-SciFi-Serie "3 Body Problem"? Darüber habe ich gestern Abend drei Stunden lange mit Dr. Lisa Ringena von IsoQuant Heidelberg & @nawik und Cedric Engels aka Doktor Whatson bei ARTE gesprochen.

Nachzusehen gibt es die ganze live Show hier: ▶️ https://www.twitch.tv/videos/2136292075

Wem das zu lang ist - in ein paar Wochen gibt es eine halbe Stunde Best Of auf dem Youtube Kanal!

Alright, sound on!

I haven't been sucessfull in integrating JMusic into my Project so far (never used external libraries before)
Meanwhile @kandid brought my attention to soundification and I did succeed at multithreading! One thread does the gravity sim while the other soundifies it: Pitch increases the closer the planet gets to the star. The pace changes with the planets speed

I've been staying up too late reading the second book in the 3 Body series.

Although the concepts in the first book are epic, the second book feels more action-packed and exciting. It's not all talking characters, but stuff is happening. It makes me want to keep reading to find out more.

Chinese science fiction history shapes Netflix's '3 Body Problem' influence - FRIDAY ANALYSIS

I don’t often get to indulge my appreciation of Sinology, i.e., the study of Chinese history and culture, but Netflix’s new science fiction series “3 Body Problem” has piqued the curiosity of many people unaware of the country’s expansive Sci-Fi connections.

“Was that E.T. or was it not E.T.? Nobody knows,” Seth Shostak, senior astronomer at the SETI Institute, tells Astronomy. “Nobody has ever found another explanation for what that might have been. It’s like you hear chains rattling in your attic and you think ‘My god, ghosts are real.’ But then you never hear them again, so what do you think?”

I went to the book swap shelf at my train station and took the first book I saw cos I needed something to read on a long flight.

And it's a perfect book. I love it. It's called City of Thieves, and it's by a man named David Benioff.

The name sounded familiar even tho I was sure I hadn't read him before. Turns out he's the showrunner for 3 Body Problem and Game of Thrones.

Love your work, Mr Benioff. Love your work.

What's your favorite reviews of "Three body problem"? Especially ones that focus on discussing the physics - both in terms of depiction of physics and physicists and in terms of how correct the books are?

Preferably of the Netflix series, but I'll also accept those for the books if especially good on discussing the physics.

Please link to them! Boosts welcome :)

Some Chinese viewers are taking issue with the departure of the Netflix series "3-Body Problem" from the original source material. https://www.japantimes.co.jp/commentary/2024/04/10/world/3-body-problem-adapting-content/ #commentary #worldnews #3bodyproblem #movies #literature #china #us

I finished #3BodyProblem last night. It's dogshit. 0/10 I hate it. If you're a fan of the books watch #ThreeBody on Prime instead. It's a very good representation of the books. If you just like random Game of Thrones actors doing their best with a god awful script that is tangentially related to the books, I guess sure check out 3BP, I'm not your dad.

「 Chaos, in the mathematical sense, does not refer to its common usage of "disarray and disorganisation". Instead, it is often characterised by what mathematicians refer to as sensitive dependence on initial conditions. This means that the behaviour of two otherwise identical chaotic systems, initiated with extremely similar (but not exactly identical) initial conditions, will eventually become vastly different from each other 」

The (Free and Open Source Software) ecosystem is a with 3 stars called Share, Learn and Adapt surrounding each other in unpredictable patterns. Depending on your point of view, the positions of the three stars change in seemingly erratic ways, but it is a very stable system, that continues to evolve and move us all forward.

Sehr kluger Text in der LA Review of Books über

„China’s sophon, TikTok, which is now on the verge of being banned in the US over fears that it’s collecting data on Americans, especially the children whose cognitive development it supposedly freezes in place. We might then turn our attention to a little red N that is doing much the same thing to its own subscribers.“

Because the latest adaptation of 刘慈欣 / Liú Cíxīn 's 三体 / "Three Body" has now been released:

A reminder that the "dark forest" concept derived from the Fermi paradox does not work.

If the assumed hostile aliens existed; they would already know we were here.

The three-body system in the story is based on a real neighboring star system called Alpha Centauri.

"We're talking about something super close to us," Franck Marchis, a senior planetary astronomer with the SETI Institute, said. "It's like looking at the backyard of neighbors, basically."
