มุมมอง 66K3 ปีที่แล้ว
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...

the quality of this video and the information deserves some sort of applause.

I'm just a casual space enjoyer and have no idea about the math behind this, but the visuals and animation are fucking stellar. I enjoyed not understanding.
FINALLY A NEW EPISODE 🎉🎉
One million comets 🗣️🗣️🗣️
The talking is so slow it sounds completely normal at 1.5x speed. With captions 1.75x is completely understandable. With that, you're likely to get quite lower average watchtime compared to video length, as people set it to atleast 1.25x speed.
bro That animation looks INSANE like man i liked everything good explaination good animation and thats great (i have an little bad english sorry if something is wrong)
Excellent work! Well referenced (so rare today). Registering right away... click!
Use an EQ to cut the bass out of your voice, i could understand you much better with -3dB on the 300-7hz range.
I had to watch it again to understand lol
great content! what software do you use for simulation and visualization? Something like Manim?
Jupiter Oni-sama!! Don't worry Earth-chan Ore wa mamoru!!!
Great job. Awesome video. Instant subscription to the channel. Thx for the video!
this was amazing
Very informative and such perfect animations❤...loved it
The analysis and animations are some of the bests
I’m gonna be so honest and say I didn’t understand even half of what you said. This was just so over my head. But I loved it so much! It’s really an incredible video and you’re an excellent narrator! I still learned a lot, even if I don’t understand everything yet.
I collected various things over the years, but I had to get rid of most them because of moving so much. After I moved to Japan in 2009, I found a local secondhand shop where I picked up a bunch of 1995 re-issues 9f some of the original Star Wars toys on their original packages. I opened them up so that my son could play with them, but he wasn't interested so much. My six year old daughter found them in her brother's room. They are currently living in her play world of Barbie, Pokemon, unicorns, and dragons😅
This video could have been a whole documentary
Do all fluids react to the Coriolis effect the same?.😮🤔😽🦜🤓🖖
The whole energy gateway explanation was difficult to follow. I think you could make it clearer with more context. At 5:08 you say "the camera starts rotating". But why do you start rotating the camera? Then, at 5:21, you say that with the camera orbiting, elliptical orbits look like flowers. But why do we care about that? What's the point of looking at the orbits as flowers instead of ellipses? Then finally at 5:27 you say "this is what we're looking for, right at Jupiter are the major orbit changes." But I have no idea how these facts relate. Do the first two things imply the third? Is the third thing just another observation? Then you start talking about an energy barrier and while I agree that the video you're showing me does seem to have an empty area, I have no idea why that empty area is there, why it is an energy barrier, or why comets can only enter and exit in the spots you've drawn. If you could spend more time talking about how the statements you're making relate to each other, I think that would add a lot of clarity.
hi, i like ur videos and ive been trying to get more into them for a while now, but i just wished taht youd explain the relevant tecnical knowledge as you go. i have a backgorund in physics but i lack the relevant mathematics that i feel are behind most of your videos. concepts such as a manyfold and their relation to energy distributions or the computational methods u use are not immeadiate to me and id love u to put some of the most relevant equations in the video to make following easier. and keep up the great divulgation content!
Amazing visuals and great audio, but I am completely unable to follow. I feel like there are 100 assumptions that aren't said, and I don't know the point. I have no idea if Jupiter does or doesn't have any impact now. The writing I think needs work to match the amazing visuals quality.
Some of the best simulations and visualizations I've ever seen!
I deadass dont understand anything

Cool story
Revisiting Einstein: E = mc²(1 + k), where 𝑘 reflects the deviation from equilibrium. Energy transitions are now linked to system stability. 𝑘>0: energy-rich, 𝑘=0: equilibrium. Could this unify potential & kinetic energy across physics? I have a more detailed explanation on my reddit under the same name. I've been posting this on channels/creators that I think may get it, and this video talks about things related.
Your animations are beautiful and your delivery is excellent. Thank you for making this!
Can't remember last time I watched such a well-produced, interesting and mind-blowing video as this one! Bravo!
As a history major, self-taught coder, and Christian, I can't help but be amazed that the simple laws of our universe give rise to such a beautiful system of protection. It's amazing to me to see the beauty and complexity of creation, so perfectly suited to us. (Or us suited to it as the case may be)
😲
Would we be arguing Jupiter merits if it had reached stellar critical mass? 🤯
A little bit summary, had to watch twice and think well to get it, but very interesting video!
I'm too high to understand anymore
As far as Jupiter's comet shield goes, is the TLDR version that Jupiter has equal capacity to send comments towards us or away from us, but that since it's more likely to meet comets on near Earth orbits than not, in practice it tends to preferentially kick comets out?
you simulate a dimension you cant see all the time, the 4th dimension is time, when you simulate 2D you are still in 3D if you are representing gravity in your model. Gravity is the curving of the 4th dimension, x,y,z=0 in a 3D world is the bottom of potential, but in 4D spacetime its the core of a massive object. There any velocity is orbital velocity and things would fall up, not down. We are bound by orbital mechanics, thats why you weigh more at the poles than on the equator, even with the extra bulge of the earth, your orbit is higher in temporal location when you have more angular momentum. So you weigh less on the equator even with less mass below you. Einstein showed how to make a 3D universe, make it all into time cones, you see potential mapped from the most massive object, all perfectly circular orbits are horizons, cut the cone across the horizon at any point, and scale it to fit your 100x100 box the same and it looks like the same cone, it will always look 13 billion years to the big bang, and 46 billion years to the CMB, they are the same illusion, that comes from a singularity expanding as it cools/evaporates. We are right at the centre, where space and time straighten back out, inside a second event horizon, its hot and compressed that side of the fence, but cool and expansive this side, as the universe with mass fills the void, it inflates, going nowhere, changing nothing. Everything with mass inflates at the same rate, you dont see or feel any expansion, but its always happening, thats why you fall down, at the centre of mass you translate at the same rate as the massive object, you are null of its gravity and distortions in time, it can inflate infinitely inside finite space, nothing ever getting any bigger, relative to eachother, massless light doesnt change, its just a propagating energy wave. it doesnt need to conform the same way the rest of us do, but a line flat and straight in time, is straight and flat in space, if you have mass. As curved as it seems, the straightest flattest route is the horizon. If you core thru the planet, it seems straight, and shorter, but spacetime is compressed, the density of spacetime isnt the same. As you walked your path your ticks change along the route, its not flat or straight in time or space, if you map for density it will show its not even the shortest route. The problem really comes down to cubes. You use them so much, but nothing in this universe works in straight lines, cubes only exist in our mind Parallel lines dont work, its all probabilities. Euclid showed us that one persons straight line is anothers curved perspective. thats the whole foundation of time dilation, 13 billion years ago the universe was already 13 billion years old in dilated space, another 13 billion years longer and its still 13 billion years to the big bang or CMB, the constant is an orbit, otherwise the planets and stars would all have been consumed as things inflated. The big bang is an illusion, the universe is semi static, there was a start point, but in a dilated spacetime you can never know when the start or stop will be. If it was a big bang then it takes more and more energy to sustain the inflation, "dark energy" you dont need it in my model..
We need it in the KKKKK-SSSS-PPPP

at 5:30 i literally gasped over these animations. i was not anticipating that! its been a while since my mind was blown like that.
god, i hope there is wifi on aliens spaceship in case i get abducted and have to pilot it back home. Or maybe i should just download it for offline use to be safe! ;) Amazing work
