I do not think you can name many great inventions that have been made by married men
Imagination is more important than knowledge.
Thank you for posting the full vid from /r/gifsthatendtoosoon
What kind of effect would the speed of the sand leaving the glass have on the way it moves? Like would the decrease in mass change anything?
I dare say that /r/oddlysatisfying would show this some love too.
I don’t understand why the ellipse changes to a circle and then to another ellipse.
It’s called a lissajous curve. It’s best defined as a parametric function. An example is x=cos(5t) , y=sin(7t)
EDIT: link to example. Try editting the coefficients (the 5 and the 7) to see different examples. Generally, the larger they are, the closer to a square it gets.
So this was extremely peaceful
Damn. I wanted to see it end.
Couldn’t you use this to calculate the rotation of the earth? I thought I read that in the “stick in the mud physics” chapter of death by black hole.
did this with paint the other day
OK, someone please explain why the pendulum moves the way it did. Someone has to be controlling it right?
How does it gain and lose momentum in different directions?
Reddit gold to whoever finds the parametric equations for this.
Excuse me, gif. I wasn’t done watching
Would love to see more sand pendulum gifs in this sub very cool
It looks like a double-sided coma astigmatism.
Edit: Oops, I meant coma aberration.
That was awesome
This is fucking amazing
Is it drawing a fractal?
I knew it. The eye of fucking sauron again.
