Not if the cup is clean enough. Normally cups have microscopic dirt or whatever. But if the cup is spotless and the water is too, then the water can get 'superheated' and go a few degrees above boiling.
Then *any* dirt will cause it to boil- suddenly.
I've done this myself. I cooked it up, without it bubbling, and then tipped some sugar into it with a long-handled wooden spoon- whoosh and the level in the cup suddenly goes down.
Apparently, one guy blinded himself- he picked the cup of superheated water from the microwave and peered at it closely. Maybe a hair fell in, but whatever it was, he won't do that again- not with that eye anyway.
Yes, but only if it is for "detection or prevention of the unauthorized use or fradulent or other illegal activities in connection with a network". Collecting statistics for advertising purposes doesn't count. They might try for dual use, but the law actually makes the second use illegal.
but I'm saying that if you want to get the most thrust from a given amount of matter(fuel) then this is the only way to go
That's quite true (actually, the correct term is 'impulse' rather than thrust); but not the point I was making.
The problem is that if the exhaust is going much faster than the rocket ever does, then the exhaust ends up carrying away very nearly all the energy of the rocket- the rocket gets very little of the energy.
So, although a super-fast exhaust reduces the fuel consumption, the energy use goes up. Pretty soon, the power generator is heavier than the fuel tank, or you make do with a smaller generator and take ages getting to the destination.
That's actually why ion drives are so slow- they don't have a lightweight/powerful source of energy.

It means that the Russians built it with 1/2 to 1/3 of the manhours that it would have taken in America, for 1/20 to 1/30 the price that it would have taken in America, and probably is a lot simpler and overall more reliable than it would have been if had been if it had been designed and built in America.
This is the exact reduced model representing the 10-km wide meteorite that hit the Yucatan Peninsula 65 million years ago at a speed of about 54000 km/h, creating the 170-km wide Chicxulub crater, and caused the extinction of the dinosaurs.
Problem is; the current evidence points to the Chicxulub impact not doing in the dinosaurs; although it didn't help.
Still, you do seem to be calling the Japanese uneducated, since presumably having sex inside wedlock is better than outside; unless you are anti-marriage for some reason.

The only way to practically get around in space is to shoot nuclei out the back of a rocket engine at the speed of light.
The problem is that energy efficiency of space drives (i.e. how much kinetic energy ends up in the vehicle, rather than the exhaust) is inversely proportional to the speed of the exhaust.
So, nuclei at 0.999c are very much *less* energetically efficient than chemical drives or normal ion drives; atleast unless you intend to travel at *very* high speeds- as in interstellar travel rather than interplanetary travels; in that case carrying enough fuel is difficult and the very high velocity drive is a better way to go.
It's not that it can't be done- it's that it is expensive to do. Forget launch costs for the moment- how much would a photovoltaic panel cost on earth that can deliver a megawatt? It's going to cost more than that on the moon.
remember we only need enough to make fuel for one rocket... over a longish period..
Yes, but oxygen gets used up by a rocket; and as I said, electrolysis is phenomenally inefficient- nearly all of the energy ends up as heat, rather than with O2 formation.
Whereas:
O2 to breath can be endlessly recycled. So I don't have any problem with this technique for that. You only really need more O2 for breathing as you reproduce, and to make up for leakage.
The partial pressure of O2 is all that matters. Apollo used pure O2 at 5psi, which approximates closely the partial pressure of O2 at sea level.
For short term survival yes, say a week or so. For long term, as in weeks/months/years, the extra nitrogen seems to protect the lungs in some way.
But you can certainly reduce the absolute air pressure down to 1/2 atmosphere or less.
Adding the nitrogen back in also reduces flammability issues- the inert nitrogen conducts heat away and makes things harder to burn. Pure oxygen is not an ideal mixture no matter what pressure you use.
That's not entirely true. Adults can live on 100% oxygen at 1 bar for a while, but it does damage the lungs, after say, a couple of days on it.
It's a bit safer at lower pressures like Apollo used, but even then, it's not ideal.
I get the impression that the issue with infants is more that their lungs aren't fully formed, and so the doctors have to administer it at above 1 bar to get enough oxygen into them. So, there's both mechanical damage as well as the oxygen toxicity. And it doesn't only cause blindness, it also causes brain hemorrhages.
The main problem is Doppler shift- as the phone moves, from the masts point of view it effectively changes the frequencies that the phone receives and transmits on, so the mast can no longer talk to the phone.
But Doppler depends on the rate of change of distance to the mast. So whilst the mast is directly to the left or right of your plane there's no problem, since the distance is relatively constant. Flying straight towards or away from a mast, the phone and mast may have big problems and you may well lose the link.
Actually, I have had crashes that I was able to relate to Winamp before.
One of the things Winamp does/did is bind to the CD autoplay feature.
In practice that means if I insert some software-only CD Roms into the drive, and installed some pieces of software from it, several minutes through the install -boom! The hard-locked/dead OS wasn't really very communicative about exactly what had gone on. It didn't effect every install, but some software became completely uninstallable.
Either way, on two different machines, uninstall Winamp, and the problem went away. Reinstall- the problem came back. Gack!
Schumacher makes more mistakes in a Grand Prix weekend than anyone of my generation in their entire careers.
Of course they were driving their cars a lot 'slower', partly because the cars went more slowly, but mostly because if it left the track, you were highly likely to die- they weren't even wearing seatbelts. F1 driver life expectancy was about 3 or 4 years in those days.
Personally, I think Jackie was exagerating for effect, but he had a point.

Actually, given the negligable shielding on power lines- their scheme would radiate like crazy and pretty much *would* be gigabit wifi :-)
Sorry, I wasn't listening.
Where will it stop?
When will you?
Yes, but only if it is for "detection or prevention of the unauthorized use or fradulent or other illegal activities in connection with a network". Collecting statistics for advertising purposes doesn't count. They might try for dual use, but the law actually makes the second use illegal.

or the apocryphal doing google searches when asked a question would be very useful.
I used to do that in audio conference meetings, I would sit at my desk and be online at the same time. Really cool.
They would be after you get a court order forbidding them from making any further sales in Britain until they pay the fine.
a) You're wrong, you can do this; it's just that your penis is attached to your boyfriend :-)
or pleasing a woman with my staying power
b) Actually, you can do this too, and you kill two birds with one stone if you invite your boyfriend to watch. See 'enlarging' :-)
Hope this helps :-)
Why don't you elucidate, and I'll get a cloth and mop it up.
Telling the truth and not being misleading are not the same thing at all, as your posting shows to some extent.

i.e. the backhanders that senators and wotnot get from 'advertising' businesses mean that the laws have little or no teeth.
I mean, in the US, it's pretty much legal to say just about anything in an advertisements. In the UK, you have to be actually not misleading.

Age of consent for girls is 13 in Japan. They can't get married till 16 though.
Yes, I never have, and now my penis is 32 foot long!

He's going to need megawatts.
Solar? Expensive to ship to the moon, and only gives a fraction of a kilowatt per square meter.
Nuclear? How does he plan to get rid of the waste heat in the vacuum of the moon's surface?
There's a reason that aluminum extraction is done next to hydroelectric schemes... no hydroelectric on the moon, that's for sure :-)
