I expect that the floor of the bin is elastic in the technical sense - it returns to its resting form when no force is applied. When the BANG goes off the base of the bin is compressed into the floor, hard. This lowers its center of gravity. Then it returns to its previous shape, the CoG rising as it does so. Once it has returned to its original position it discovers, rather to its surprise, that it's now travelling upwards, and so it continues to do so.
As well as the shockwave mentioned elsewhere, you also have pressure effects.
The initial explosion drops the pressure in the bin below atmospheric pressure. Assuming there's enough kick to separate the bin from the floor, you've got a higher pressure pressing up on the bottom from below than down from inside the container, so the bin accelerates up.
I'm not sure if it'd be a significant effect, however.
It seems I'm the only one who agrees with you. The project is really cool in itself. Saying I'm 14 makes it difficult to judge whether people are truly impressed or just impressed this was done at 14.
It certainly is impressive at 14, but I suppose I dont feel like we should be making 14 year olds feel like they're less capable.
Then again, in the end its a matter of questioning the purpose of Show HN. If its to boost your ego, and there's certainly nothing wrong with needing that from time to time, adding the circumstances helps. On the other hand if you're looking for improvement, it seems better that people look at what you made without the bias or lowered expectations.
He's 14. That is a very relevant part of the story here. Seriously, he should be very proud that he accomplished this at 14 and should be comfortable sharing that with everyone. I don't think he needs to be criticized as if he's as far along with his career as most others on HN. I think the feedback will be much more encouraging, plentiful and helpful for a 14 year old.
From a strictly technical point of view, it is at least some form of Artificial Intelligence:
1) From the perspective of the Turing Test, it biomimics human behavior and intelligence.
2) The field of artificial intelligence deals with a computerized comprehension of data. ACUMAN is heavily dependent on machine learning, natural language processing, and text classification algorithms, which facilitate understanding. It also gathers psychometric data, which allows the machine to take its communication with a participant in context of their personality.
3) A computer able to interact with a human in a similar way that a human would with another human. ACUMAN matches this definition because it accepts and can converse in both speech input and text input, all in the english language and manifesting its "intelligence" in the form daily communication.
The project qualifies to all three of these pieces of criteria.
Edit: just realised you're the author, so I want to reiterate: this is a lovely designed app and making your own chatbot is rad. Original reply below.
Re 1. Yes, it does attempt to pass the Turing test.
Re 3. Yes, that includes interacting with a human in a similar way that a human would with another human, that's part of the Turing test.
My own experience was: it asked me how I was, I told it I had a hangover, it thought that was great and that I was 100% happy. Which wasn't a long test. Obviously your own experience might have varied.
Re: 3. Isn't machine learning just machine learning and NLP just NLP?
I personally don't feel like my app suddenly becomes 'AI' if I import nltk and start tokenising some corpus to train it with, or load opencv and tell my drone to avoid the big red thing. If the app would work out how to /train itself/ I would consider it an AI.
Eg, the drone having the objective to follow me at a safe distance for as long as possible, then working out that the big red thing is dangerous and avoid it.
Or the chat both to, say, have an objective of beating the human at the turing test for a certain amount of time, then working out how it gives itself away, then avoiding doing that.
I acknowledge that's just a feeling though, and many definitions online would qualify 'thing that loads library and needs human training' as AI.
However I can't help but think that's going to promote the Reading University 'captain cyborg' school of cranks.
