#142A non-US perspective: it's quite weird hearing someone younger than about 50-60yo use inches as a measurement. Especially for something scientific.
Do you mean the reference to four-by-two timber. It’s not really measurement when it’s a standard size like that. More like a well known discrete unit like a pint of beer or a 54” pizza.

#143Does it bug anyone else not to have the analytic solution?
I don’t blame anyone for opting for the numerical solution, but yes: a solution by analysis would be impressive.
Perhaps it could be done with the parabolic antenna solution with a frame of reference change, to account for the acceleration due to gravity?

#144Absolutely brilliant. The plot twist requiring the additional metal bracket at the end was fantastic.
To err is human. To own it on YouTube, divine.

#145This was really well explained and interesting. Funnily enough I'm pretty sure this is a really similar method to urinal design, so if this whole basketball thing doesn't work out for ya, you could always work for American Standard...
The design idea is also similar to the the original stealth fighter design, the "hopeless diamond"[0], in that it's optimized to bounce all possible radar waves away from returning to their receiver.

No. When he measures the ball to move the hoop

Oh right. With a precision caliper no less. Another video posted here the other day used the word thou (as in thousandth of an inch) which is a word I haven’t heard in a long time!

One of my favorite software solutions that I came up with was “human learning” powered. A few years ago I was working as the engineering manager at a small company. I had 8 other people who I was in charge of and we had moved to a new office in the middle of this. Our team took up two rooms in the office and I had to figure out who would be sitting where. I had some preconceived notions of who would be productive tog…
Is this how sports schedules, NFL, NBA, etc are made?
They are heavily based on divisions and recent seasons.
(For example, in the NFL, the teams in each division play each other twice, and then get the rest of their games by rotating through teams from the rest of the league)

You could definitely improve / take advantage of rim interactions, for instance, and more easily not have the problem he has with the lower corners.
There are obvious ways that the physics engine might be able to capture more effects than a simple analytic solution of parabolic trajectories. But if it only lets you run the simulation forward to get a trajectory from initial conditions, then you now have a numeric optimization problem as the body of the inner loop of another optimization problem. If the physics engine can't efficiently solve the inverse problem he…

Isn't solving the physics problem a straightforward ODE integration?

My intuition suggests that you can't do better than simply angling towards the hoop for an average shot. The author simulated shots from tons of different angles and speeds, but I'd bet the shape is actually the same if you just assumed it was always coming from the center, at an average speed, at an average arc, aimed at different points of the board. So just shape it to make the average shot aimed at each points go in and you're probably at the same level of efficacy.
Similar to how the MLE of a gaussian curve is just... the mean. Could be wrong! Though fwiw I don't think the video actually shows him shooting from a variety of angles, and I don't think the board would actually work that well if he wasn't centered. Could be wrong again!
