Is that a Newtonian moral imperative, a quantum moral imperative, or a relativistic moral imperative? Science can help optimise toward a pre-existing ought (the moral imperative not to kill, for example) but it has nothing to say about wha

Perhaps these problems can't be solved by society? The amount of misalignment of (putative) intent and effect in education I've seen, especially at the policy level, at least suggests this. If that's true, the question you

Ironically, I've mostly abandoned big-name news sites to listen more to people like tptacek. What I see in the papers is mostly people pushing a story, usually with seemingly little technical expertise, and without the important conte

In general I'd agree. But in this case we see the sort of destruction of language George Orwell warned about. By legitimising a use of the word "literally" which is counter both to its etymology, and to the intention of tal

I can confirm from first hand experience that, regardless of the quality of the Bitcoin transaction experience, the quality of the beer here is absolutely top notch. Also the food is very good and they have a pretty decent selection of boa

Not entirely fair. While there is a lot of choice about how to define stuff around the edges of mathematics, after the axiomatic choices have been made, there's quite a lot to discover in their structure. Particularly if the relevant axio

Sorry for the delay everyone, I'm currently working on a consulting project, which was going to finish mid-August, but is now potentially slipping... I'll have to confirm my exact availability before I can accept anyone. I should know by t

Yeah, I'd like to know about fractal geometry too :) Sadly not in my field, but good luck! To help with book learning, try adding interactivity back in, e.g. by writing a short blog post on each small topic you want to learn. This will swi

Thanks for the suggestion, and I share the sentiment, but I'm not going to do that. I'm happy for the student to record them and later upload them if (s)he wants to, but I don't want to commit to broadcasting because: 1) I'd rather not hav

1) Much more practice at teaching maths and physics, and it's much fresher in my mind, so I reckon you'll get higher quality out of me that way. 2) I expect more demand for maths than physics 3) A lot of physics and machine learning is ma

Well, I upvoted you. Thanks for posting clickables, I'm actually not sure how (do you just put HTML tags in the text?) So, hope that cancels out.

Couldn't get to the Beers section, assume you're in the middle of updating it? It would be really great to have a way of tagging or arbitrarily grouping beers together, e.g. "fruity" or "goes with Salmon" etc, as well as by obvious characte

Thanks for the replies. For those who like the betterexplained explanation: 1) Did you understand the bit with the limits, or did you find the thing made enough sense without that? I would have thought that would be harder than introducto
