However

This is just nonsense and quite distracting, even irritating. Quantum computing and quantum mechanics is hard and involves sophisticated concepts. The spaced repetition questions are utterly superficial and represent unhelpful dumbing down.
Apologies for the rant and slightly silly comparison between quantum physics and a programming language but the same goes for the Rust book. Rust is a hard language with sophisticated ideas. Despite the best intentions of the nice people at Mozilla, no amount of dumbing down changes that. And patronizing readers does not make the resource more approachable to women and under-represented minorities, unless you believe that those groups need to be patronized.

I can see why you would think that. However, consider the following points:
1. One of the authors is/was[1] one of the most well known experts on quantum computing, and he literally wrote the book on quantum computing.
2. He has written elsewhere on how spaced repetition really helped him understand new disciplines and read journal papers.
So while you may not like spaced repetition, think twice before saying "unhelpful dumbing down", given that it really helped him, and he's very clearly not a dumb person.
There's no harm in simply saying it doesn't work for you. I suggest you examine the need to justify that by making broad statements.
Perhaps there's more to the Rust/Mozilla story that I don't know of, but going from the example you gave and connecting it to making things approachable to minorities is a giant leap I'm having trouble fathoming.
And while the statement is annoying, I did not find it in the least patronizing. I don't doubt that it helps some people, and I think you need to realize that not all books are written for you, and that there likely won't be any book that is good for everyone. If you don't like it, find another book - don't expect the world to cater to you.
When it comes to technical books, particularly math/physics text books, everyone has his/her own opinion and that's OK. There's no shortage of people who hate math books that give too many examples ("Just give me the theorems, proofs, and maybe one example!"), and there's no shortage of people who want examples and hate books that are "theorems/proofs". The same goes for pretty plots, color coding important theorems, etc. Yet not once in my time in academia and beyond did I hear someone say "These distracting elements and examples are dumbing things down and are patronizing, and it's because they're trying to appeal to women and minorities!"
I really think you need to introspect about your world view that led you to these conclusions. You're being triggered, and you need to own your reactions.
> Quantum computing and quantum mechanics is hard and involves sophisticated concepts.
Although I didn't study quantum computing, I have done plenty of non-relativistic quantum mechanics at the grad level. It's hard for only two reasons:
1. Lots of introductory books start off with calculus-heavy problems (infinite square wells, harmonic oscillators, hydrogen atom, etc).
2. It differs from real world experience.
Plenty of people have advocated that item 1 above is the problem, and it is not a good way to teach QM. You get lost in the calculus and don't focus on the QM. There are plenty of advocates (e.g. David Mermin) who think QM should first be taught using spin, because it involves no calculus, and the linear algebra is necessary (and not sophisticated). Almost all, if not all, the fundamentals of QM can be taught that way, and it's not that hard. Certainly a lot easier than much of your introductory physics material (mechanics, EM, etc).
[1] I say "was" because he has left the quantum computing research world.
Is it the notion of embedding SRS questions into the medium per se. that you find superficial and unhelpful, or just the specific questions that Andy and Michael chose? If the latter, would you suggest any alternative questions that might be less patronizing / more effective?
It's comments like these that in high school made me avoid calculus. Just wanted to let you know that you are discouraging. The youngsters reading this that are still developing their critical thinking skills are being scared away because of your projections. Frame it different, take responsibility for your inadequacies.
It didn't strike me as discouraging at all. Discouraging would be something like "QM is so hard that 80% of people reading this are too stupid to learn it" (which I don't think is true, FWIW, so don't be discouraged by that)
Just because youngsters don't have critical thinking skills does not mean they will read words that aren't even there. If anyone does that, it's on them, the reader, and no psycho-analytical word smithing will fix that.
OK. If you are a student reading this then, well, firstly I'm not at all sure you're feeling discouraged from learning about the nature of reality and potentially world-changing computing frontiers because someone on the internet said it was a hard subject! But if you were, please don't be. Here's why.
Firstly, a lot of incredibly valuable and interesting things do require a bit of concentration and effort. I'm sure you know this.
But there are reasons to be optimistic! Here are some things to do:
1. Stay calm! Don't give up.
2. It's not at all obvious how to read technical stuff to start off with. Basically, the secret is to read the same paragraph a LOT of times! Everyone does that. No-one can understand it by reading it through once like a novel. If you find yourself reading the same paragraph 100 times you're on the right path because it means that you KNOW you haven't quite grasped all the ideas yet, and so you are becoming your own teacher in a way; setting your own standards for yourself.
3. You've got to be, or become, the sort of person who can concentrate on reading something challenging, in a quiet room. Talking to others is going to help a lot also, but there's a private side to this. You can compare it to training to be on a sports team at a more competitive level. There are going to be times when you're doing fitness training or whatever, and you're on your own, and it hurts because you're exhausted. You know this was always part of the deal.
4. Don't listen to the people who tell you that it's "easy" and "anyone can do it". Yes, anyone can do it in in the sense that everyone has the biological potential to do it (they're human, they have a perfectly good brain). But you know perfectly well, just by looking around at your classmates that some people don't have, or at least don't currently have, the attitude that's going to let them do it. You don't have to be weird; you just need to let one side of your personality be a studious side, occupying some fraction of your time.
That came out of the blue. Am I missing something? Did mozilla make such an attempt to patronize minorities?
Some fun history here: Ruby uses #{} for string interpolation. I used to teach Ruby to folks as a job, and I believe that my boss, Jeff Casimir, said that they looked like lobster pincers in one of our classes. (If Jeff reads this and that's incorrect, my apologies!)
Years later, when I was writing this part of the book, I remembered this analogy, and we had the whole crab thing going on with Rust, and I thought it was a fun thing. So I put it in the book.
Some people find whimsy inherently patronizing or something. I dunno. It's an offhanded fun comment, not some sort of desire to "dumb things down" for anyone. We don't write anything with the intention of dumbing things down.
I realise for this audience most people wouldn't get much from it, but I find these rules useful for explaining quantum theory without annoying and fluffy analogies to high school students. You can find the rules in my book _Q is for Quantum_ - Part I which covers quantum computing is a free download on the book website (and the rest will be if I ever get around to producing a corrected pdf, bleh, but if you read part I and don't want to pay for the rest let me know and I'll get it to you...)
What were the powerful ideas?
I say that not as a physicist/mathematician looking down at the oiks trying to underastand this stuff, but as one of the oiks.
I really believe that we are just now starting to scratch the surface of the learning opportunities that computers present to us and Quantum Country was an interesting step forward in that direction. It is worth looking at some of his previous work with Khan Academy as well, cool stuff.
>I must confess, I don’t understand what people mean by this.
I think they're just trying to tie it to Schrödinger's cat somehow since that's the only other topic that seems to be covered in pop science.
It does make sense that if we're going to have learning interfaces they have spaced repetition built in rather than requiring users to do that themselves.
Looking forward to reading through.
