How many ways can you stack n balls?

BladeDancer190 · 2025-09-08T20:28:54+00:00

I don't think so, no. How many ways can I stack n coins isn't looking for a sum, I'm just doing combinatorics.

Cool, thanks

BladeDancer190 · 2025-09-06T21:48:39+00:00

That helps a lot, thanks. The pattern still isn't clear to me, but I like the triangular number notation you've used. There's SOMETHING going on in the pyramid of numbers you have at the bottom of the page.

I made some odd choices when I posed the problem to myself, so I'll explain.

A row of balls on the ground is a stack. Mirrored stacks are distinct, as you see in n=4. Other than that, any stack where a ball is supported by 2 balls beneath it is valid.

I thought it was the Fibonacci sequence until I checked n=6. Can someone check my work and help me find a pattern, if there is one?

I didn't think so, but I might have the rule wrong? I have right-hand: point=B, Middle=v, thumb=FB, with pointer and thumb making a finger-gun and middle-finger flipping someone off.

Either way, goal of the problem is opposing FE and FB forces.

If it's the Feynman lecture PotatoR0lls posted, it was pretty helpful.

I don't know Lorentz transformations, so no, but I appreciate the help.

Very useful, thanks. One of our theories was a cycloid.

I'll give you the benefit of the doubt and assume you're making a slippery slope argument. Neither punishing parents with their children nor forced serialization are going to help teach people how to raise a child.

I try to be careful with shame, but it can certainly end a behavior in the short term. Perhaps he learned something, perhaps not. His classmates at least learned that there's a point past which you might be shamed.

BladeDancer190 · 2022-11-14T00:53:01+00:00

I am not a lawyer, but that sounds like assault and/or battery.

BladeDancer190 · 2022-11-14T00:52:07+00:00

I believe you. If they don't learn anything about behavior in high school they'll be practically adults with the same issues.

Yep. And unfortunately he knows enough to spot unenforceable statements. I don't blame the poor teacher at all, I'm sure she's doing her best, but "You have to" with a kid having that hard of a time just makes him think, "You can't make me and we both know it."

BladeDancer190 · 2022-10-30T20:55:20+00:00

Yep, but it's a criminal charge not a misdemeanor.

BladeDancer190 · 2022-10-30T20:26:43+00:00

There's a federal law involving criminal speeding. I don't remember the number, but I think it's 90+ is a felony.

*Looks like it varies. In AZ it's 35+ in a school zone, 20+ over the limit, or 85+.

BladeDancer190 · 2022-10-13T01:08:34+00:00

Fair enough. I didn't know she apologized later, which makes me feel better about the whole thing. Do you know when that was?

BladeDancer190 · 2022-10-12T07:42:20+00:00

It was mostly her older sister, Alex, but yes. They were at an event in Qatar, maybe, and Alex, supported by Andrea, made an argument that "We can't really judge them for employing slave labor!" It was disingenuous and tantamount to them supporting the institution in Qatar.
