Comment Re:In Finland, teacher spots are hyper-competitive (Score 1) 213

In my experience when I was in school, the best teachers I have encountered were always passionate about the subject they teach. You rarely get people passionate about a subject they are bad at.

Yes, they may not be very well equipped to deal with kids who don't want to learn, but on the balance, it would be better to let down kids who don't want to learn by a teacher good at the subject but at handling rough kids, than to let down kids who DO want to learn by a teacher good at handling rough kids but bad at the subject.

Good points. I agree that being passionate and creative about the subject goes a long way, at least in subjects like experimental sciences with hands-on lab work and fancy demonstrations.

However, there's the whole side of education/upbringing about working with kids/teenagers in general that is hard to gauge when you're applying for a degree in teaching. You have these 19-year olds fresh out of high school who say they love to work with kids, with no idea about the real challenges of the career, and it's hard to pick out those with the right kind of potential. Frankly, it's the same with a lot of professions, and naturally people will end up changing their jobs/studies later.

Personally, I first got a research-oriented Master's and ended up working as a teacher for a couple of years, and finally completed the teacher training. Some of the material was a joke for anyone with real experience - for example, a prominent professor of education says he's worked one full day as a school teacher.

I also remember reading that about 90% of Finnish teachers graduated in the top quintile of their class. In the US, that figure is more like 4%. American students of education typically get the worst SAT and GRE scores of all the majors. We cannot ignore these facts when we're comparing educational systems. In the US it's easier to get into med school than it is for a smart Finn to get into teacher school. The quality of the people who make it through means that pretty much every innovation they try is bound to produce satisfactory results, because highly their best and brightest are in charge.

Consequently, we have a lot of geeky straight-A's teachers (mostly female) who are unable to handle the rougher kids.

Disclaimer: I'm a Finnish teacher, having taken a longer, more hands-on route into the career, but I still find myself a bit too geeky for the worst cases.

Why would she need anything specific ? Any entry level laptop will have more CPU and GPU capability to do whatever she's gonna be asked. I doubt she will end up doing fine-grained world-wide weather simulation

For heavier computations, scientists generally have access to supercomputers, clusters and the like, so the CPU/GPU capability should not be an issue. Also, it's obvious that the laptop should be able to run Linux, there's really no question about it. For example, you'll want to develop your code locally before booking supercomputer time, and once you get there, it's nice to X11 there directly.

It might be a good idea to get a proper AMD/Nvidia GPU, both for 3D visualizations and GPU computing -- of course, it won't be hugely powerful, but it's the same point about local development before farming out.

Comment Re:Wireless charging hit mainstream ~ 1-2 years ag (Score 1) 184

Also, I love how you think inductively charging your wireless toothbrush is "sensible" but making it easier to keep a life-saving device like a cell phone fully charged is, apparently, not.

Screwing around with micro-usb is a lot more practical when you don't have to worry about a wet environment. Of course, there are also waterproof and otherwise more rugged phones, so inductive charging makes more sense for them.

Also, in such a comparison, you need to consider how many lives are actually saved by _easier_ charging -- somehow most people manage to keep their phones charged with old-fashioned connectors, and only a tiny fraction of all phone usage is related to saving lives. Of course you'll get a non-zero number; now compare that to infections, heart disease etc. caused by not keeping your teeth healthy.

On a more general note, I think charging should be as simple as possible, not just for the user, but on a technical level to keep things more reliable (hence saving more lives). A lot of phones manage to screw up this idea even with wired connections: for example, you cannot run a phone off a charger alone, without a battery.

I imagine wireless charging hardware is not just a dumb induction loop, and some device identification/negotiation needs to take place first. For example, leaving metallic objects on the charging pad might be hilarious without such considerations. This IMHO is needlessly complicated for something that should be simple and reliable. At least, the extra comms takes up some power, making the efficiency even worse.

Real Nerds know that you need AC for wireless charging, DC just won't cut it.

Seriously though, my opinion as a physicist/engineer is that wireless charging is a little dumb. It wastes a lot of power in an age where energy conservation is paramount, for what exactly? It's not like you can charge your phone from a distance. Inductive charging is a sensible tradeoff in things like dil^Welectric toothbrushes -- just because it can be done, doesn't mean it's great for everything.
