jgamman··on Elsevier journal editors resign, start rival open-access journal
Your impression is probably correct. For instance, The Economist magazine's editor is finally learning some science during his retirement[1]. Heaven knows what he thought of their tech quarterly supplement for 50+ years...

I suspect Elsevier's upper management layer is dominated by the PPE set of the Oxbridge upper class.

jgamman··on A Fairy Tale of F# and Durable Functions
as does Mathematica. v useful for pattern matching as the hook for the function.

What's with the playboy bunnies as the team avatars on your homepage?
jgamman··on Orbits and orbitals (2006)
One useful way to think of each year of chem/science study is to assume _it's the last year this student will take the subject_. From that perspective, the student will spend the rest of their life with _this_ mental model.

When viewed like this a mental model of a nucleus with electrons 'orbiting' around it is entirely valid and literally drops the student in the early 20th century.

One of the problems with experts is that they try building a straight line from zero to expert that never needs a backtrack step.

Personally I like the opportunity for students to learn about the experimental evidence that _forces them_ to need a better theory than the one they've come in with. Cognitive dissonance is one of the most powerful forces students have for learning - a good teacher should be engineering these moments as part of their lesson design.

IIRC this was a policy decision change only 20 odd years ago. (also, not a lawyer or USAan)
jgamman··on A Tiny Austrian Town Has the Coolest Bus Shelters (2014)
maybe the point is not to be overly functional but some sort of art trail that people hop on/hop off normal PT in between cafes and galleries etc. for a small town, even a few hundred tourists per month on weekends can make a huge difference to the economy. maybe someone else who knows the area could comment on the route.

jgamman··on Kathy Sierra – A Computer of One's Own
this deserves a title change. another successful woman forced out of tech by trolls and on-line abuse.
jgamman··on T.M. Landry and the Myth of Meritocracy in Education
Geena Davis (actress) picked up archery at 41 and got to 24th in the US. Resources count since she _started_ with an Olympic coach. Imagine if she had the access and desire at 14...

jgamman··on The Spacing Effect: How to Improve Learning and Maximize Retention
anyone quoting BF Skinner should get an Audrey Watters reply: check out http://teachingmachin.es/timeline.html
jgamman··on How “One-Plus-Five” Is Shaping American Cities
another thing to consider is that approx. half the emissions associated with a building come from heating and cooling during its lifetime. saving 10% in carbon for the construction and then skimping on say, double glazing and passive solar means you lose out over the long term.
jgamman··on A Programmer's Introduction to Mathematics
I try and write a tutorial about a subject-chunk - the kind of tutorial that i think would have made sense to me if I'd read it before writing it. you have to suspend the obvious fact that by writing the tutorial you've learnt more and probably wouldn't have understood it at the beginning anyway but let that go for a while.

part of writing the tutorial is exercises - i like a stripped down flash card system. i try and do random-10 as regularly as possible. at the beginning, there's lots of jargon with scripted answers (ie, what is a blah?) but after a while you can move those to the back and you're left with some multi-step questions - over time (because i'm not trying to memorise the answer pattern) i find that i internalise a kind of narrative that uses the concepts/jargon to grope my way to the answer ie, hmmm looks like an aqueous equilibria question, probably need the equilibrium expression (jot that down) and HCl is a strong acid, so i can ignore those two terms and oh look... there's the answer if I just do this and that. Over time, it's the 'groping for an answer' that sticks as a habit of thought and seems to be quite robust. having said all that, i'm craphouse at maths but i'm hoping to get into one day.

we had similar childhoods - those Rats books were like a horror movie that lasted for days till i finished each book ;-)
jgamman··on Elon Musk considers move to Mars despite 'good chance of death'

jgamman··on The present phase of stagnation in the foundations of physics is not normal
i think its one of the classic logical fallacies - you can't disagree with me unless you have a better idea. it's a false dichotomy in the sense I can think you are wrong without further explanation. unless there's expt evidence but most of this is opinion-based so it's not open to that sort of progress.
jgamman··on NYC subway and bus services have entered 'death spiral', experts say
i think that's literally ones of the objectives of under-funding. then privatise. then monopoly rents for those that can own shares. while still under-investing - who cares about trains? just uber a private jet/helicopter.

jgamman··on Major Study Finds ‘Some Evidence’ of Link Between Cellphone Radiation and Cancer
At this point in time it's not really relevant to say cellphone vs no-cellphone. It's death by cellphone vs saved by cellphone ie, you need to compare how many people have been able to call for help in an emergency, get a taxi rather than drink driving etc because they had access to a phone in their pocket.

It's like comparing new drugs to the best off-patent generic, not a placebo sugar pill.

It's all about the UX right?

I scroll down on my mbp laptop and the @#$@#$ pictures move to the right...

jgamman··on How I Became a Knife Steel Metallurgist
email the PhD guy who wrote the website you've just commented on and ask if he will recommend/supervise your personal learning at the rate of 50$/hr (or whatever).

Aside from the credentialing problem, you will get an amazing return on investment - just view it as buying hours of your own time _not_ wasted on @$@#$# youtube videos.

If you're an over-achiever, you might negotiate a lower price on the understanding that the curriculum he develops (with your feedback/experience) for you stays with him and he markets it on the forums he has credibility in.

jgamman··on Quitting my job has been the best thing I've done for my career
in NZ (and Aus i guess) we call this an OE (Overseas Experience) and it is incredibly common for someone in their 20's to up sticks and bugger off to the UK (and others) for several months or years.

They/we aren't, for the most part, privileged - they land in London with 50 quid, buy an A-Z at the airport and doss with friends under the kitchen table till they land a job doing whatever. Save and party until summer and then a long af van trip around Europe seeing the sights. Rinse and repeat if you've got the stomach for it. Variations exist.

The leaving your country part is the important part. Even if it's English speaking you'd be surprised at the resilience you need to just get s* done arriving somewhere at midnight with no idea where you're going to sleep.

Being punished for 'gaps' in your CV is a cultural thing. There are no gaps in your life, just... life.

tl;dr US shocked (shocked i say!) that other countries doing the same sorts of things they do.
jgamman··on Ask HN: What's a “rare and valuable” skill that is not programming?
Be good-ish at 2 or 3 different things - one of which is programming which has a leveraging effect on anything else you learn (just trust the default libraries). Being good-ish at 2-3 different things (as a strategy) is rare and if you're actively looking you can translate that into valuable.

I hate Excel. I use it extensively every day. It is amazing.
jgamman··on The First Rule of Microsoft Excel: Don’t Tell Anyone You’re Good at It
it's not excel that's the problem - it's you or your replacement 6 months later trying to reverse engineer the iterated solution that you willed into being... ;-)

maybe the opposite is true too - SV/US has more innovation because there's absolutely nothing to lose and you can't expect to eat/medical because US.
jgamman··on In Math Cram Sessions, Solving for Why
the best teacher(s) in a 'bad' school overlap with the worst teachers in a 'good' school. Keep in mind that there is a relationship between student and teacher and that clicking with one teacher isn't guaranteed or that after a year of growing up, you might click with a teacher you didn't get on well with the year previous.
