  1. I like these projects but... on New Musopen Campaign Wants To "Set Chopin Free" · · Score: 1

    My problem is that I tend to not be so interested in the heavyweights, I much prefer lesser known composers, such as Chopins contemporary, Karol Szymanowski.

    In any case, Chopin composed numerous highly patriotic songs (as in music which is sung) as well as folk songs which aren't explored much, and devilishly hard to get good recordings of. Musically good versions of those should be worth it.

  3. Re:Not necessarily inconsistent on The STEM Crisis Is a Myth · · Score: 1

    In my engineering course, one core subject was about "engineering enterprise" which was more or less a general business subject tailored for engineers. The lecturer gave one example of data showing different sectors of the economy, and this data gets collected and used by governments to compare themselves against other countries. The point he made was that they look at an economy which is going well and basically try to copy them.

    I'm in Australia, so one of the metrics was STEM which Australia has quite a lot less than countries like Germany or the USA. My experience is though that there aren't the jobs in Australia to support larger numbers of STEM jobs. Just with engineers, only 8% work in manufacturing here, 24% in sales and the rest in consulting (broad sectors of engineering, I know). So Most of the engineers aren't really doing particularly productive work.

    The reality is 'training' more people in STEM won't necessarily create jobs, and I think that's where the Article has missed a point. The politicians think that there's a shortage because some other countries economy is better and they have more people working in STEM. I think that the real problem is that the politics is incredibly undercooked.

    Bit off topic, but;

    Sometimes i've wondered. There's so much espionage around, and so much information that can potentially be gathered, surely these spy agencies have people who are the beneficiaries of industrial espionage? or even information come across by chance. I get the feeling that there just has to be a bit of you scratch my back, I'll scratch your back when corporations, or even individuals get into bed with the spooks.

    What does google get in return? If they're prepared to hand over data to the likes of the NSA, what do they do with the data themselves? Are their privacy policies worth anything at all?

I certainly don't like living in a state of Australia where the constitution states that the parliament can make a law for whatever reason it wishes (with a couple of minor exclusions).

    One thing for sure is, playing a game will most probably make you better at playing that game. Cognitive flexibility, on the other hand, I think their definition and testing methodology for that is a little bit wanting. Nothing is mentioned about whether the participants were just learning how 'play' the testing. Like you are dealing with an area of study which says that you can't study for an IQ test, but people can and do, and improve their results.

    Newspaper sales aren't as important, it was the classifieds. According to Pamela Williams (Fin review editor or something), who wrote the book 'Killing Fairfax' she stated that classifieds were 60% of the revenue, and they were cheap to produce. All those classifieds are now a tiny fraction of what they once were.

    Basically for newspapers like the fairfax ones to keep their churnalism going, they need some sort of low cost way of bringing in money. The journalism part isn't really selling papers (although it has moved online as well, but there's a lot more competition online as well), and as a result isn't valuable enough to keep journalists employed.

    The thing is the NBN isn't cheap. You will be paying at least $70 per month for 100mbit connection with only 30gb of download data. For a more generous download allowance, you are looking at $100 per month. I currently have 24mbit adsl (get about 1.8 megabytes per second top download speed) with 50gbyte download quota, that costs $30 per month, to get a comparable NBN plan in speed and quota, I'd have to pay $50 per month.

    There's corruption in Australia when it comes to getting government contracts. The Government appears to be able to pretty much select any offer irrespective of price. The current prime ministers wife is an excellent example, she has businesses which turn over hundreds of millions, all of them with only one client; the government.

    Maybe you could just point out where in Aristotle's work he says that.

    Since you can't, I think I might just say that In the times of Aristotle, a teacher was a mentor, they had few students, and didn't have a classroom; they were sought out by the wealthy or privileged because they had achieved great stature and notoriety. That is at odds with the learning institutions for the bulk of people today. Pupils are supplied a teacher, who isn't likely to have made any significant achievements in their area of study, they receive a fresh cohort each year and quite often they have to deal with kids who don't want to be there, more than themselves.

    Yes, to be able to teach properly, it certainly helps to understand, I for one have found that until I could explain it to someone else with ease, I didn't understand it, but, how many school teachers are like that with the content they attempt to teach?

    How many will tell their class to ditch the ipad due to the gimmick that it is, and revert to the tried and true methods of learning and study i.e. pen/pencil in hand?

    Just an anecdote, I remember when I finished the last of my exams for my compulsory education, there was a period after where school attendance was still required, when teachers were asked why we couldn't go to holidays sooner considering we had practically finished our formal education, he explained quite clearly, if they let us go, the crime rate goes up.

  24. Re:Why? on FAA Wants All Aircraft Flying On Unleaded Fuel By 2018 · · Score: 1

    the lead in petrol had a few benefits, it raised the octane number, allowing the engines to have higher compression ratios, providing better thermal efficiency of the engine.

    now we have variable valve timing and low pressure turbocharging, which does the same job, albeit with more parts. as a side benefit, though, you also get to reduce weight.

    No, cam timing and turbocharging do something completely different. Compression ratio relates to the thermal efficiency of internal combustion engines, which relates to how well the engine is thermodynamically extracting work from combustion. For spark ignition engines, this thermal efficiency is purely related to the compression ratio, the higher the compression ratio, the more efficient the engine, thermodynamically, and provided that optimal timing can be achieved without detonation.

    Turbocharging increases volumetric efficiency which only explains how well an engine is using its displacement; variable cam timing does the same thing, it optimises volumetric efficiency against RPM. The fluid mechanics of the air, having mass, can be exploited to ram more air into the cylinder with higher velocities, so longer duration will give better results at higher RPM, but provides woeful performance, and very bad emissions at low RPM, as it pushes unburnt fuel out the exhaust.

    As for the hardened valve seats, yes that's the case with alloy heads, I suppose I assumed people would know aluminium isn't as strong as cast iron. However the aircraft engines may further require the leaded fuels for lubrication for added reliability. I don't know much about aircraft engines, but i daresay, that if other comments about them having significantly more tetraethyl lead than car engines ever did, then it could be that they use more mechanical systems for added reliability, such as fuel pumps, maybe still carburettors or mechanical fuel injection.

    the lead in petrol had a few benefits, it raised the octane number, allowing the engines to have higher compression ratios, providing better thermal efficiency of the engine. Also in the era when engines where made from detroit wonder metal (cast iron) certain parts were lubricated by the lead, so they could remain as cast iron, such as valve seats, whereas unleaded fuel has required hardened valve seats to be inserted.
