That's what the last guy said- right up until he found out that she had watched him put the keys away. OK it's a hypothetical "last guy", but let's see how you rule it out...

If I could be bothered I would look up the solubility of hydrogen in water- under great pressure. Marginally. Producing hydrogen under pressure requires a slightly higher voltage than at 1 atmosphere. In principle, the increased energy use in the cell is (unsurprisingly) the same as the energy that would be needed to compress the hydrogen if it had been generated at atmospheric pressure...

This is in danger of becoming a "no true Scotsman" argument.

Which makes her much more likely to be a shooter than if she lived in my, gun-free, house. Since there are deaths caused by 4 year olds with guns, the observation is not functionally useless- you can act on it by removing the guns from the house. Will you? Also, it's important to recognise that a "good man with a gun" might be even less use than shouting at Republicans. http://www.bbc.co.uk/news/world-us-canada-43164634

... by Trump...

Is that really a serious suggestion?

Submarines (at least the nuclear ones) are not noted for energy efficiency. I always assumed they vented teh hydrogen. It's not flammable under water, and by the time it gets to the surface, it is someone else's problem.

Ask an American how to spell it. It's a comment on the fact that they just like to get my language wrong.

You missed out the bit that makes it clear that you are talking about an instruction rather than an equation LET I=I+1 Granted, most languages permit that bit of sloppiness, in much the same way that chemical equations have energy changes bolted on with no regard for decorum. Especially if a banana costs 7 cents, and an apple costs 3. Or if a apple weighs three ounces, and a a banana weighs 7

This For those outside the US, acetaminophen = paracetamol. isn't wonderful.

Last time I checked, "race" wasn't a well enough defined term to be much use in science. On the other hand https://en.wikipedia.org/wiki/Heterosis

It should say HCL + 10 H2O = HCL(aq) If you are interested the energy released by this reaction is 16.61 kcal per mole of HCl or a tenth of that per mole of water. They got lazy.

Roughly as wonderful as the inability to spell "colour", and equally irrelevant.

The fact that they even mention the MMR vaccine is a big red flag. It doesn't get better when you read the actual report "fewer children with ASD vs. non-ASD children use acetaminophen as a “first choice” compared to “never use”" Read that through a few times. Yep, they say that fewer autistic kids use acetaminophen and then the conclude that acetaminophen may be a cause of autism. They go on to say "We found significantly more children with ASD vs. non- ASD children change to the use of ibuprofen when acetaminophen is not effective at reducing fever (p = 0.033) and theorize this change in use is due to endocannabinoid system dysfunction. ". I have a different hypothesis. Parents of kids with ASD are frazzled. If their child- who is already hard to deal with- gets a fever and is thus even more challenging, they are more likely to try another drug than the less frazzled parents of kids without ASD. To follow that they say "We also found that children with ASD vs. non-ASD children are significantly more likely to show an increase in sociability when they have a fever (p = 0.037) " Well, just for a start, how objective is a measure of "an increase in sociability"? But even more tellingly- what they are saying is that kids who are - as a baseline- not very sociable are more likely to become more sociable than kids who were sociable to start with. I'm not sure that a journal called "autism open access" is an entirely unbiased source.

Yes. That's more a matter of sloppy use of language than an equation. (Lower case "l" in HCl BTW)

You need to revisit what the law says about consent. It's also not consent if, for example, he says "I will kill you if you don't let me..." It's not consent if she's not old enough to ... whatever... It just wasn't consensual. Meanwhile, back at the topic...

No the horse is a perfectly normal earthly nag. I just employed a rather unusual horsebox.

Given that, for example, socialised healthcare and education plainly work in many parts of the world, why would anyone say that "they don't believe they work"? They must have been misled. Perhaps someone told them that socialist systems don't work.

I can buy a MHz sampling CD quality A to D converter for less than the price of a decent beer https://www.mouser.co.uk/Semiconductors/Integrated-Circuits-ICs/Data-Converter-ICs/Analog-to-Digital-Converters-ADC/_/N-6j74v?P=1yrsx0d&Ns=Pricing|0

My horse was delivered to my home by alien rocket ship and was, therefore, the fastest horse on the planet ever. But it's an old nag and can barely run faster than I can.

What, in principle, stops me getting a sax (and someone who can play it), a microphone, a pre-amp and an A to D converter; then recording the voltage from the microphone as a function of time? If the sound doesn't vary over time* then I can "loop" the sample I have and make it arbitrarily long. And then I can Fourier transform it (the long version means I don't need to worry much about apodisation). I can then recreate that sound by digital synthesis from the Fourier coefficients and, apart from a few minor distortions that I can generally reduce by simply paying more money for the kit I use, I will have a "copy" of the original sax sound. * (if it does, I need a better player- one who can hold a note)

About 30 years ago, at the height of the cold war there was a joke, something like "thieves broke into the Kremlin and stole next years election results". Today they could do the same thing, but the results would be those for the Whitehouse. However, the man in the Whitehouse is only there because of the Russian's influence, and he plainly wants to stay there. How hard is he going to try to stop the Russians?

Forgive my ignorance. Do the same companies produce military guns as well as civilian ones? If so, how much market share does ech sector have? If they get millions from domestic gun sales, but billions from military ones then a boycott won't work.

Who, and why?
