Hi! There's a paper airplane I've made which I learned out of a book a while back - the book called it either a "condor" or "albatross", I forget which, but searching for either of those names turns up different designs. It's an excellent glider, and one of the few designs I know that start with the paper in landscape orientation. If you're interested, here's how to fold it: - With the paper in landscape orientation,…

Ha! I remember these being my go-to as a kid. Classmates always ended up taking them home so I must have been doing something right.

If you give me a realistic physics environment to train an agent in I'll do it for you.

I wonder if anyone has attempted to use machine learning to try and build a realistic physics environment. I feel like that would be super interesting.

Maybe we're already living in it? ;)

I mean, I know this is probably not in your control and all (and I know I'm off-topic). But wouldn't an adblocker be appropriate for your school environment? I most definitely wouldn't want my kids to see any ads, but obviously and especially those with "significant skin exposure". I applaud you for not recommending this site in the first take. But it seems like you should have more support, adblockers being the firs…

Ad-blockers from the point of view of UK copyright would seem to be tortuous copyright infringement (unauthorised modification and/or unauthorised creation ofa derivative). I can't see schools here using them because of the legal risk.

So you're saying, adblockers in the UK are illegal due to copyright concerns? I don't think that holds. If I buy a magazine and rip the ads from it, that's perfectly fine. This logic even holds in a school setting.

Flight physics don't scale down (or up) well. It's the predominant reason small airplane and quad models have enormously unscalable performance characteristics and abilities. Making it bigger doesn't "just work"... same for the inverse.

I think the physics mostly DO scale down, it's air density and gravity that don't.

Imagine my surprise when I'm reading down the HN list like I do every day and I stumble upon my own website. Thats a pretty cool feeling! Im happy to answer any questions people may have. This was my Angular learning project back when Angular just came out. I think Angular ended up being the wrong choice for this project, but it works and I learned Angular, so its all good.

Which one flies furthest? (I can narrow down by category, but not sort).

Very interesting, I wonder how regional these are. For example I grew up with this one as the "basic" / default: https://www.origamiway.com/plane-nakamura-lock.shtml Notice how it has a high air time and distance. I used to launch them them from my 8th story apartment in the city. On a right day, some would take off and would be carried by the wind to where I lose sight of them.

This is the design I always made as well (except I usually brought the top wings all the way down to the nose)

Actually, it doesn't - you can't take the ads out (eg a clipping service) in any commercial setting. Using a tool that you put your newspaper in that removed all ads would be creating a tortuous derivative too. There's no general personal exemptions in UKCDA either.

Chances of being prosecuted for use are roughly zero.

Lawful educational use is highly restricted in the UK, but there are few prosecutions. For example if you show TV broadcasts you have to have both music licenses (as well as the TV license) to cover you for when they play music on the show (or in the adverts!).

"Time of flight" only the definition of flight was something like unpowered and untethered off the ground. So floating slowly to the ground becomes "flight" by the definition of the rules.

Wouldn't the burning of the paper technically make it powered?

No, the burning of the paper removed a great of mass from the paper turning to to a brittle paper ash. After the fire was out is when the timer started, since the paper ash was so much lighter but the same volume its buoyancy in air was drastically increased causing it to "float."

The up draft from the flame wasn't utilized to power the flight, the fire was only used transform the original rolling paper into a "plane" by mass reduction through combustion.

Similar story from a university aero course that ended with a paper airplane competition. There were some remarkable paper airplanes, making amazing flights, all sorts of research and time went into developing the ideal model. One guy comes up representing his team and he gets out a piece of rolling paper and a lighter. Tears the tiniest portion off the rolling paper, sets it alight, and then follows it with his fing…

You can use a light paper and a board that you walk with to provide lift; I'd have thought that would create a "thrower stays behind line" rule.

There was a team that did this, as long as they didn't create an up draft it was legal by the rules, their air time was still less than a minute.

The burnt ash wafted for well over 60 seconds.

When I used to teach AP Computer Science, I'd have my students make paper airplanes on the first day.

I'd have them write down the instructions to make their airplanes. Then I'd follow their instructions in the strictest, most literal sense possible, resulting in some lopsided airplanes.

It was a great beginning lesson in algorithms.
