Think of Kerbal Space PROBABILITY. Extended video incl. chapter 5 - www.patreon.com/braintruffle Topics • Interplanetary transport network • Manifold hopping • Weak stability boundary • Lagrange point orbit bifurcations: Lyapunov - Halo - etc. • Low-energy transfers: 4-/3-body model - effective potential - Coriolis force - zero-velocity curves • Phase spaces (n- vs. 1-particle) • Oberth effect ...
Building the simplest fluid simulation that still makes sense
Переглядів 142 тис.2 роки тому
A vivid introduction to fluid simulation. Topics covered: rarefied gas dynamics, continuum gas dynamics, fluid motion descriptions & coordinates (spatially fixed (Eulerian), material-fixed (Lagrangian), arbitrary), reducibility aspects, motivation on modeling unresolved flow structures, ensemble averages of microscopically and macroscopically varying data, usefulness of the modeling hierarchy, ...
Running back in time is *not* recalling the past
Переглядів 64 тис.2 роки тому
This follow-up discusses fluid simulation related information reduction in view of time irreversibility of the governing evolution equations. We gain an overview of a statistical perspective on the microscopic motion and highlight the implied time irreversibility as well as the exclusion of anti-dissipation. Topics covered/used: Kinetic Theory of Gases, Boltzmann Equation, One-Particle Phase Sp...
How do you simulate what isn‘t there - and still make sense of it?
Переглядів 206 тис.3 роки тому
This is the second part in a series about Computational Fluid Dynamics where we build a Fluid Simulator from scratch. We derive the Macroscopic Perspective (Continuum) from the Microscopic Perspective (Molecules) covering: Collective Molecular Behavior, Local (Non-)Equilibria, Classical Statistical Mechanics, Rarefied Gas Dynamics, and Continuum Gas Dynamics. The Macroscopic Perspective provide...
Fluid dynamics feels natural once you start with quantum mechanics
Переглядів 2,4 млн3 роки тому
This is the first part in a series about Computational Fluid Dynamics where we build a Fluid Simulator from scratch. We highlight the Microscopic Perspective on Quantum Mechanics, Molecular Dynamics, and the Kinetic Theory of Gases that underlies and justifies Fluid Simulation Formulations in the first place. The Microscopic Perspective provides the ground for the next part where we focus on th...
I read somewhere that if the sun were to just vanish that its gravity would still have an effect on us because gravity waves travel at the speed of light. If thats true then technically the orbit of jupiter would lag behind jupiter the farther away you got. Interesting to think about
Thank you
I can only imagine how well you know your animation software. It’s quite beautiful and complex.
My takeaway: Space is like an ocean that goes in all directions, so you have to go in elliptical loops to propel yourself to reach a certain point, and math constructs models of all possible locations you can know when to propel and where to drift into the right direction.
That is really interesting.
Wow those manifolds are so beautiful!!! I feel like they are hinting at some deep secret pattern of the universe.
Amazing video as always, you are super inspiring to me!
All glory to God, He designed a very good system
Jupiter & Co couldn't have life of their own, but they helped Earth get some.
If we get taken out by an asteroid that came from the kuiper belt, we probably deserve it.
I've been trying to subscribe to less channels, but you ruined that plan.
30 yrs ago🤔
Loved the incredibly instructive animations and diagrams. Surely whatever the perturbations do, swinging rocks in our way or throwing them out further, the sheer number of rocks that have fallen in has reduced the overall risk. I'd love to know how many of those million random asteroids ended up diving into Jupiter's atmosphere.
Anjayyyy
I would love to see everything represented in 3d
Qué maravilla de videoclip por favor!! Espléndido!!
Great animations, AND approachable explanations. Good stuff.
Youre telling me Jupiter has curves?
Who wins? 1 million comets vs Jupiter
Mind blowing
Awesome visuals man what the hell. So good.
lmao @ the Astrocolloseum
So Neptune, Uranus, Saturn and Jupiter all play a role in keeping comets away. They can't protect us from everything, but its only thanks to them we're here to talk about it.
Roman cities from Space strike the Earth's surface.
I do not think that these models take into account that the mechanism drivers dynamics vary over time.
0:05 sorry but how can they know it had a colosseum similar to that of the one in Rome on it? isnt that highly unlikely?
Lol
Just discovered this channel. Love it!
What they never want to talk about is that the impact craters on the earth, was probably pulled in by Jupiter as well!
wow, what animation software do you use?
So beautiful graphics.!
Golly! Your visuals are amazing! Please keep making these interesting videos! 🌟
The amount of cosmic “accidents”required for us to simply live as we do is crazy.
“Size of the Colosseum up to Rome’s inner city” as an American. It feels wrong to say this, but can I get a measurement like an actual measurement? I could work with meters you were standard measurements are not imperial they’re just metric. Seriously how big was the asteroid?
Wait a second: Doesnt this imply the work of scanning for earth impacting comets gets way easier? Just have very powerful equipment staring at this gateway, you'll see comets coming potentially years of orbital trajectory in advance
Now I won't tell I understood everything of that. But I've been wondering about that for ages! Thank for the video!
Your analysis stated that when an interstellar object comes from outside the solar system plane, these objects sometimes have so much energy that they cannot sustain an orbit within Jupiter’s. Additionally, you stated that for objects coming laterally (that is, head on towards the plane - as depicted in the 2-d model), then these objects must come through the manifolds. My question is if we ran these simulations in a 3-d model, whether changes in an objects’ trajectory of an object coming from above and below the lateral plane of the solar system could result in earth crosser orbits. I really enjoyed this video and i look forward to see a simulation that takes account the 3-d simulation an and any other conclusions we might draw from them!
0:06 Coloseum in space
Speak faster, this is not a preschool.
this is art
Wow!
Nice work!
More videos like this.
This video and explanation of orbital gateways was spectacular. Thank you for making it.
Love your to-scale visuals!
What an incredible video! Thank you for the amazing work!
So chicxulub senario?
Astronomy is one of the few things that feels like real magic, the way we can map and observe and predict things lifetimes away from us, things we will never truly witness or possibly be a part of
This video is amazing
All this talk about astroid gateways, then there's 'Oumuamua " *LEEEROY JENKINS* "
Anyone watching this after knowing the 3 body problem
