Ellipse reminds you of its focal points
Ғылым және технология
A couple of hundreds of balls are arranged along a vertical line at the center of an ellipse boundary whereafter they all move towards a point on the reflective boundary.

I'd say that would lose some information about the "density" of the formation. Or at least the ease of noticing the changes, since you could still use the colours for that, albeit with less ease.

I love this one green ball which doesnt care about what hes supposed to do and does his own thing
Interesting. At any moment, all of the balls can be grouped into arcs, of circles of different radii, but all centered at one of the two foci. When a ball bounces, it changes which focus it's centering on.
1:36 this also shows the butterfly effect as the two green dots become asymmetrical due to tiny imperfections

Butterfly effect. Minor deviation at one point that lead to completely different trajectory pattern than the other dots in its initial proximity
@BarderBetterFasterStronger

@@artursruseckis4242 I'm not sure this is a very good example of that. All the balls started at different coordinates with different initial angles of movement. The previous commentors question was more, why is the single green ball so out of sync when all other balls continue to follow fairly clear patterns. I think the variance of the paths of the balls seems to increase exponentially the closer it passes to the focal points of the ellipses. After a few viewings, you can see that the "new" circles in the pattern always appear first from the sample of green dots. Indeed, I suspect if we had a denser or continuous serious of dots (hey, that's a line) the single green dot's strange trajectory would just be part of the newest formed circle, one that the other dots in the video were not close enough in starting position to also be a part of. In a way, the first dot to appear out of sync with the others just implies that dot's closeness to being in line with the two focal points. You can also see that by the 5th/6th bounce, none of the dots' are even on the equator of the ellipse. And if you follow the paths of the closest green dots, by the 7th bounce, there would have been new circles forming that we can't even see because none of the dots were in line with the focal points enough to show them.

@@artursruseckis4242 Clearly not. If you watched the other vidoes of this channel you would get a better idea of what butterfly effect really looks like. It's fundamentally different from what's happening here. Here, the green dots diverge in a very regulated circular pattern. The new, very large green circle cannot be correctly represented simply due to the limited number of the dots, but it's still a very large circle as apposed to being chaotic.

@@mingyue_chen it is still a good representation of butterfly effect. All the green dots start at nearly the same point, but their small deviation ends up separating them further. This is a great video to see how the horizontal axis has more deviation to the rest of the ellipse
I'm cheerin for the lil green guys
sheesh. I have seen ur ellipse vid. That was amazing!
Beautiful.
I just knew the elipse would be the most fascinating conic section to do this sort of simulation with ... VERY captivating!
Fascinating.
This is awesome geometry!
I could watch this for like an hour
As someone explained a while ago under Nils Berglund's video, the reason is because points will always go through the horizontal axis on the same side of the foci they started in : • If the point first goes between the foci, then every bounce after that will make it pass between the foci again. • If it first goes between a focus point and the "wall" of the ellipse, then every bounce after that will make it pass between a focus point and the wall. In this case, every point starts out in the middle, moving towards the rightmost point of the ellipse. That means every point goes between a focus point and the wall. Try to imagine the line between the two foci, and watch that line. You'll notice that, except for a single point that's sitting almost exactly on that line at the beginning, there's never a single point going through it ! And so, they will spread out, but never actually go between the two foci, eventually "circling" around the foci. To show this, I'd love to see another simulation, but this time clearly showing the foci and the line segment between the two, and with the points starting in the top right corner, moving down to the right of the focus point. We should see them "circle" that line, but never actually cross it.
If you were to place in the ellipse points of a random angle, but visualized them as near transparent circles, it would highlight areas where the points become concentrated
Ive never felt this calm before in my entire life
This was mathematically truly beautiful.
let this thing go on for an hour pleaaase!
I have no idea what I'm watching... but for some reason, I can't stop
Love it to watch this
The fact the the green balls that were sort of outliers ended up coming back to the main constant area thing is just incredible!!!! Math, wowww?!,!
I wonder if we would see the same divergent behavior with the green balls, if those were idealized points, instead of finite sized balls. Would they stay in line with the rest of the balls if they were? And if the balls were larger, would we see more spreading like the green balls?

Жыл бұрын
the erratic green balls formed their own "circle", and it was also the leading one. but there were only 5 balls to fill it, so it looks like they were singular divergent ones, but if you pay close attention you notice that they also constantly meet at the focal points

@@unitrader403 I've been wondering if the appearance of single green point seemingly floating around by themselves with no matching mirror symmetric counterpart on the other other side of the ellipse might be an illusion caused by there only being a finite amount of discrete points? Maybe the chain has just spread out so much by that point in time that the simulation is down to only a single point it can display, even though there's actually still a a constant continuum of a single wave, and it's forced to put that one dot somewhere that is either moving into the upper or the lower half of the ellipse. Or it could be a tiny rounding error at the start of the simulation that keeps getting bigger with each bounce.
this is kind of like how light focuses to a point on curved mirrors
@JW-oe6nw

This is exactly how light focuses to a point on curved mirrors! Parabolas and ellipsoids have foci which by nature of ellipsoids and parabolas are always in the resultant set of reflections of points passing through a focus. The beginning of the video has the points converge to the focus of the ellipse (or so it would seem)

Those are circles. But their center shifts inwards over time. So these are not the focal points. The centers probably drift to the focal points, but that is just a hypothesis right now.
