Comment Re:Science is dangerous and math is stressful (Score 4, Interesting) 246

When I'm doing my safety lecture, I'm always demonstrating why some behaviours are not smart. Either by showing videos and photos, or actually doing an experiment which "goes wrong".

Much better if pupils know why some stuff is forbidden.

However, I'm, also showing them that the acids and lyes they'll be working with are not something to be massively afraid of. Respectful, yes. Afraid, no.

110 V is not lethal - hurts like a bitch, but lethal? Nope. The AC makes it even less dangerous. Plus, if 110 V were lethal then how do you think people survive being hit by a taser where the voltage is a multiple of 10,000 Volts?

It's the resulting current, the amount of charge transferred and the length of the current which make electric appliances dangerous. But at 110 V you almost have to work hard to kill yourself.

I actually expect a modicum of general knowledge from teachers and not merely the particulars of their field. And it should be general knowledge that a) a circuit board is not explosive and b) for a bomb to be explosive it needs to have actual explosives.

Not to mention there's this small matter of how serious they actually were about this "bomb" (as pointed out by another poster downthread):

They did not evacuate the school. They did not call the bomb squad.

THAT alone should tell you all you need to know about those guys. And now go away. Try to find excuses for some other abhorrent and idiotic behaviour, you won't have much luck here.

Maybe you should take a look at a movie sometime. What does a "movie" bomb show? Lots of blinkenlights and circuitboard (in addition to the explosives, natch). So, the only way you could mistake an electronic clock for a bomb is if you equate "circuit board and lights equal bomb".

No disassembly required.

They are retained because Germans like such restrictions, not because anybody is forcing them to

Suuuure. In your righteous crusade against the stupidity of Germans, you're overlooking some realpolitic problems with your sentiment.

First of all, such a move would be political suicide. Political opponents of the politician proposing such a move would rejoice because he just gave them a big, fat bullseye. And don't tell me that other countries are better in that regard.

Secondly, there's the international level to be considered as well. Israel, for example, would be thrilled while we would probably get applause from countries like North Korea. Yeah, that will work well.

I'm not quite sure why you're lambasting him for suggestion unions by listing the times where unions were indeed a hindrance... because he made this very point himself:

Can unions abuse their power? Absolutely, so stay involved, vote in your union elections, make sure your union reps are doing their jobs.

Or did you only read what you wanted to read? In fact, I think you stopped thinking the moment you read the word "unions".

Comment Nothing "odd" about the required update (Score 5, Informative) 27

The required update isn't "odd" because it facilitates two things:

First, it checks whether you're a owner of a affected device or not.

Second, if this is indeed the case it then facilitates getting the RMA number in conjunction with the website.

Basically, you go into "System" on your device, check the battery, it tells you that you're affected. You then open the website, enter the serial number of the device. You get an RMA number, and enter that into the device. You then get another number (some kind of receipt, probably) and enter that into the website, along with your contact information.

Sounds more complicated than it is and you're done in about 4 minutes, depending on how fast you type.

The article talks, among other things, about biofuel cells which target glucose - so, actually, yes, using those devices would lead to weight reduction. Because that's one of the more important ways to distribute energy throughout the body: delivering glucose where it's needed which the cells then convert again in the citrate cycle to more readily usable stuff.

Thus, using machines based on this kind of fuel would lead to weight reduction the same way it would when you exercise.
