OK, so 235 kg of U_235 has the same number of fissile units (N atoms = 1000 x N_a) as 5 kg of D-T has of fusible units (2N atoms of combined weight 5 amu, or 1000 x N_a pairs) so (ignoring the N_a for now) one kg of U_235 gives 200 MeV &#x2

Except for the fact that the sort of person who cannot come up with USD 400 in cash is also the sort of person who has a poor credit rating and no credit cards, and most likely their peer group of friends and family are in exactly the s

But even that is pretty vague, since a single Uranium atom fission event releases about 200 MeV of energy, whereas most of the Hydrogen/Deuterium/Tritium/Helium/etc. fusion pathways release around 10% of this per fusio

I'd believe Lockheed Martin's CFR claims more if they didn't say things like this: > Energy created through fusion is 3-4 times more powerful than the energy released by fission.[0] Which is just confus(ed/ing) on a f

Yeah, a Petawatt is huge, there is nothing on earth (well, see next sentence) that can provide that sort of average power continuously. For comparison, 4PJ is basically the output of a kiloton nuclear weapon, so one second of a PW laser nee

Someone who wants to buy 100 of those airplanes, but knows that the safety option reduces the risk of incurring a $100 million total hull loss by less than one percent, thus saving less than the $100 million extra cost for the option? O

Also, in our CS lab anyway, theft of the shiny mouse pads had evidently been an issue in the past, and they were often glued or otherwise attached permanently to the desks. But why? And who? No student back then (early 90s) could even drea

Indeed, what they (members of said sub -culture) all are is collectively different to, or in some way deviating too far from, whatever the current social norms, mores, or accepted majority cultural standards are. In this way, the group

Yes, and did you know most data centres add evil back doors to the machines you rent? The secret hardware is codenamed 'LOM' apparently...

I'd suggest that if you genuinely don't understand this sort of social thing instinctively, then you're probably on the autism/aspergers spectrum then. I really wasn't trying to be offensive towards you or anything,

It's pretty simple, and really not caused by people attempting to appear unique. There are two main factors: 1. All humans has a need to be accepted and approved of by their peers, 2. Humans also have an essentially identical neural ar

You would never say 'nominally', rather just 'nominal' to avoid confusion on noisy radio nets.

Interestingly, that's higher than the ppO2 at sea level, which is about 3 psi, or at ~5K feet (standard airliner cabin pressure) where it's 2.5psi, so they were still running at almost double the amount of oxygen available normall

FYI, I think your terminology is slightly non-standard though - (UK) english normally would describe any device worn on the head which allows you to listen to audio as either 'headphones' or 'earphones' interchangeably

it turns out that even mp3 encoding audio doesn't actually stop it being audible to other people nearby when played through speakers, the headphones on the other hand, mean only the wearer can hear it...

And also, annoying for Echo device users, since the use of the word 'Alexa' will trigger the device, and thus mute/drop the volume so that you can't hear what is said next... I guess it could be worse, since the volume r

The problem seems to be there is no barrier to entry. Say what you like about Apple's app store, at least they have standards that are enforced, and to a certain extent Google as well. Windows, and the Microsoft app store, on the other

OR... the Internet and eBay have made watch collecting accessible and broken down a lot of the barriers to entry that used to exist, and were jealously guarded by gatekeepers. Yes, the likelihood is that most collectible watches now cost

This is a strange thing to believe - fines exist for deterrence, not income - the purpose of a fine has failed if it ends up being paid, since it didn't deter the offender! In the UK, for example, about GBP 80 million in speeding fin

No, that is NOT what the 'tamper' is or does. See my (or various other) nearby comments where I describe the actual process, or just read the Wiki article linked in another comment...
