My curved basketball hoop always goes in

Check out the subreddit:
I've wondered if it is possible to make a basketball hoop where the ball always goes in. Imagine throwing a ball and if it hits the backboard it somehow gets directed into the hoop. Thanks to physics it isn't quite possible to make ALL possible shots go in though you can make a hoop where the ball goes in a lot more often. In this video I show how I wrote a program to calculate the optical backboard then machined and fabricated it. It worked out better than I was expected so I'm really happy with it!
These videos usually take 100+ hours of work and a lot of money in tools and materials. I've made a patreon if you're interested in supporting the creation of these projects:

    Awesome video! You have done an awesome work, I wish you dedicated more time to the code, it would have been fun to see the reasoning behind it =) Given that you've done the code to compute the shape of the paraboloid, do you have the exact equation of its surface? How does the speed of the ball influence the calculations?Would it be possible, given the exact equations of the paraboloid, the sphere, the circonference of the rim and distance of it from the paraboloid, to create a program where just by adjusting parameters of each geometric shape you can be sure to replicate your experiment? Like for example if I change radius of rim and sphere, I instantly get as output the new equation of the paraboloid and the exact right distance of the rim.

    Others have mentioned it in part, but I looked it up since I've used it/been around it so much - the Monte Carlo method is just a reference to using inputs with randomness to determine statistical outcomes by just running simulations or the actual experiment until results converge to a reasonable significance. Name comes from... "In 1946, nuclear weapons physicists at Los Alamos were investigating neutron diffusion in fissionable material. Despite having most of the necessary data, such as the average distance a neutron would travel in a substance before it collided with an atomic nucleus and how much energy the neutron was likely to give off following a collision, the Los Alamos physicists were unable to solve the problem using conventional, deterministic mathematical methods. Ulam proposed using random experiments. [...] Being secret, the work of von Neumann and Ulam required a code name. A colleague of von Neumann and Ulam, Nicholas Metropolis, suggested using the name Monte Carlo, which refers to the Monte Carlo Casino in Monaco where Ulam's uncle would borrow money from relatives to gamble." - Wikipedia, "Monte Carlo Method",

    I'm wondering if it's possible to make an optical illusion with this that makes it look like a regulation backboard up to 45 degrees from it's 'face', or rather the wall it's mounted on as the face isn't a flat surface, but you get the idea.

    This is really cool. I would be interested to see a different application of this gradient descent shape. If you applied this concept to the keys of a computer keyboard, perhaps it will feel more ergonomic than traditional keyboards. I've noticed that good mechanical keyboards generally have shapes that shift upward if that makes sense, so I think you would have to adjust accordingly. Cheers, I love your work!

      ​@Terrance Thorpe Basically The rims are oval shaped so they look right from the front but if you get a side on look it's clearly wrong. There also the wrong height and distance away as compared to a regulation free throw show according to Mark Rober's carnival science. Depending on how much the rim is distorted it can be anywhere from difficult to impossible.

    If you imagine the center of the board has moved back from the stationary rim, rather than the corners projecting forward, then the rim is in the right place.

    I know it's a Hometown to work but I would really like to have seen the rim up against the backboard not set 2" further away. I think it might have changed the shape of the backboard to be closer to traditionally flat and thus make it look more like a normal backboard.

    Most goals actually have backboard below the longitude of the rim so that could change things. And there is a protrusion from the backboard to the rim. Also maybe make the next one full size? This would change the angle but I think it would be advantageous to you at a flatter angle.

  • Jake Ryan
