Besides, beryllium is EXTREMELY tightly controlled ; mostly due to its very interesting properties when building "uncontrolled" nuclear fission devices (ie, bombs). Beryllium has the very interesting property of being a very good neutron reflector, which means that if you coat a mass of fissible material with a (thin !) beryllium reflector, you reduce by two or three the critical mass.
Also, Beryllium can be used as a source of neutrons (when bombarded with alpha rays), which again, is a desireable property when building certain types of devices...
Both effects have been put to use even since Trinity...
see the HEW archive at http://www.enviroweb.org/issues/nuketesting/hew/in dex.html for more design details (search for Beryllium there).
In short: don't show up at an airport with some Be on you. You'd Be In Trouble (tm):-)
Hey! Another one who writes before reading what he's responding to. Tell me, how did Napoleanic french
people manage to measure light traveling in a vacuum for that short a time? The pole to the equator was the
original measurement.
...
But there are no other units of length in metric. I can do the same with feet. millifeet, kilofeet, megafeet.
Had metric did that, they'd have their base 10 system and be compatible with existing measurments.
Reasonable, yes? But noooo, they had to be an ass and come up with something totally incompatible.
1) it was not "Napoleanic" people. That undertaking was done in the early 1790's, way before Bonaparte was even talked about.
2) the first definition of the metre was indeed a decimal fraction of a meridian, and the measurement of the meridian was indeed made by measuring the Paris-Barcelona one.
HOWEVER, choosing a meridian instead of, say, a parallel (such as the one going through Washington, DC) was not innocent. With even ten times the measuring accuracy of the era, all meridians (including the one going through OK city) lead to the defining the same length of a metre. The goal of the scientists who designed the unit was precisely so that "once everyone has adopted this system, no man needs to remember who adopted it first or invented it".
Quick rebuttal to your "compatibility" proposition (mft,ft,kft,...) :
1) at the time, there was no such thing as a "standard" foot. There was one per MINOR city in Europe. Yes. Every damn city here had its own system for lengths, masses, volumes (only time was more or less already standard, which is why "metric time" has never taken off and was totally abandoned around 1807. Well, the metric calendar had other design flaws, too). Usually, that per-city system was even more messy than the mess you use in the US. (and look, that mess makes NASA loose Mars probes. Damn morons). Being uncompatible, wiping out the unit mess of the older times was a design feature. Just before the French revolution, the little people was asked to write down doleances, so that the King could see what was urgent to improve. Believe it or not, those people were tired of converting everything but money when travelling a few dozen kms.
2) the mft,ft,kft is not a system. To make that a system competitive with metric, you have to build the rest of units, and express the physical constants in the new units. That means you have to choose which of the various ounces you'll drop to keep just one. And besides, why wouldn't other use yard or mile-based length units ? This is precisely why there is no other unit of length in the metric system : duplicates are evil, and both a loss of time and a loss of usefulness.
3) Why would you loose time designing that "decimal us" system ? You'd be an ass and come up with something totally incompatible. AND NOW, there is a definite, internationally agreed upon standard (which wasn't the case in 1793) : the metric one. Live with it.
And just how does one precisely collect this exact amount of pure water to define the mass unit? Scrape the
top of a 1 cm cube filled with water really fast with a knife. And where yo you get "pure" water? Now that's
precision! Sorry, the block of metal in the filtered air vault in Paris *is* by sheer decree exactly
1.00000000000... kg. And it's a kg because 1g is too light to accurately calibrate anything with.
Actually, "pure" water is easy for any chemist to make (at least, "pure enough"). As for the volume, any moron can build a container with a volume of 1 cm^3, even if the actual shape isn't cubic. And it's then easy to measure the weight of the liquid+container, substract the container's weight, and then build equivalent metallic masses.
1g is too difficult to weight ? Well, current weighting accuracy is more in the nanogram range these days... BESIDES, you can always take one thousand of these cubic centimetres, lump them together, and make a kilogram weight. And you won't have a weird fraction of whatnot in your way.
The original gauges stored in Pavillon Baltard are long since obsolete.... and never really useful, since physical definition (that is, definition using physical features available everywhere) is the whole point of the metric system.
You've never dealt with a third? Impossible.
Who cares to ? If.33 is not precise enough,.333 or.3333 will be. And that I can compare with.7351 or.23158
This is insulting at best. We have enough problems right now (end of holidays) with people taking 20-hour long drives across a single country (and no, they don't precisely drive at 70), and being the cause of accidents.
Besides, not only you can drive across the whole West Europe for more than 30 years (more or less, depends on the gov't type 30 years ago), but there's a well overdeveloped road freight consuming both infrastructures and fuel (and providing our lungs with plenty of those healthy microparticles).
As for the taxes... Most are here since the 1973 shock, as a means to drive the poor out of driving. Even in France, where the current prices are ridiculous (up to 8F/L for Unleaded98 --> $4.2/gal ! (please notice than the $ is currently quite expensive. That means Airbus doesn't need military subv^Wprograms to undercut Boeing, but for us simple beings, that means even more expensive fuel)), this has pretty much failed...
The result was an obvious pauperisation of those who couldn't afford living near their jobs or bear with 3-4 hours a day in public transportation (usually, the public network isn't as bad, but access from the ghettos and trash cities is pretty much cross & banner).
Anyway, I'm glad my new car will be delivered soon (mid-september). Trading a 8L/100 U98 car with a 4.7L/100 Diesel one (Diesel is 5.35F only around. Phew !):-)
>> For example, with a normal car, when going downhill the engine is in idle and its still
using juice, but nothing is being produced. In this situation, the gas would be off and the battery would charge.
<<
This is mostly untrue with modern, injection-driven engines (both gasoline and HDi/TDi/JTd diesels). Those engines consume zero when there's enough gravitic potential energy to be consumed in place of petrol -- ie, when you're driving downhill.
Also, another problem with the hybrid gas-n-electric-n-a-bunch-of-batteries is that this precise bunch of batteries is heavy, which tends to lower the overall efficiency of the design.
You'd be amazed by what a modern, 1.4 EDI (Renault/Nissan's GDI) or a 1.6 HDi can do nowadays... Iff the electrical consumption and shocks can be managed, camless engines are also going to bring gasoline back in front (currently, HDi's (and kin) are the most "economical" mass-produced thermic engines available. "economical" and not economical, because they cost a bit more to manufacture (and there are well-deserved patents to pay, too)).
... On the other hand, some good folks developed tunnels which spoof English-text HTML-over-HTTP or English-text SMTP mail, and use this to route an arbitrary bidirectional binary stream, and make that appear like a standard tunnel network device (read : you can then put basically whatever you want on top of that. Which includes TCP/IP+SSH)
Cons ? Horrible bandwith waste.
Pros ? Virtually undetectable, until firewalls actually try to understand what's in these pages or mails, *and* enforce that it actually makes sense, *and* enforce that it's plain standard American English. And that day you can be sure there's going to be quite a huge uproar....
Search on Freshmeat. It's truly amazing.
Sure, this is plain *S*L*O*W*, but with 2005 "censored" bandwith, still getting 1999-ish bandwith levels with 1999-ish freedom would be a nice middle finger up to the Octopoly's faces.
[OK, due to TTL reasons, the SMTP tunnel can be easily defeated with an arbitrary 10 minutes delay for every piece of mail. But the intergalactic TCP extensions will take care of that use case, too]
One NetAdmin at my former univ. did log every IP packet header of connections involving "outside" to a (by then) huge partition. And that wasn't a specially small-traffic site...
Actually, you don't need a PROM (or, exactly, you don't need a specific PROM : the Duron/Tbird surface copper contact rows can be seen as a special-purpose PROM in its own right). All you'd need is a way to read the copper contact values (some mechanism like CPUID) into the processor's registers.
The problem is, the BIOS is waaaay out of control from AMD (or Intel). There could be "black hat" motherboard sellers which could quite easily sell "mute" motherboards (all motherboards sold right now are "mute"), so that the luse^Wconsumer still get screwed.
I owned several Supra modems (from the time Supra was still an independent quality). They simply *rocked*. And with that continuous speed panel... Mmmm... still getting nice chills thinking about it.
Well, on "attacking" a McDo : it was still in construction ; this is nothing like ramming in a restau^Wfood delivery place with a loaded AK-47 and then walking outside with the same AK-47, now unloaded.
On "vandalising" : actually, they dismantled it, just like you can dismantle most parts of a car (McDo's "architecture" is really standard pre-fabricated parts which are really quickly assembled).
Finally, the goal was to bring in the media. And that succeeded. Tremendously. (being on/. doesn't account. Being on CNN, with semi-non-events from a 20K inhabitant-town in a really deep rural region of a now quite small country, while doing no harm to anyone (except those poor McDo bricks) *is* a quite feat).
and no, I doubt vandlising a construction site is protected free speach, but not being up on French custom, I don't know for sure
Of course it isn't:-) See the BBC article or http://www.legifrance.gouv.fr for a preview of what it could cost...
However, one of the claims in this trial, is that the construction site was not destroyed or vandalised, but simply orderly dismantled. The goal was not to cost a lot to McDo, but to bring in as many of the media as possible (last August). With his three weeks of preventive jail, this has been a tremendous success...
On a side note, José Bové is a real media protest "professional" (let's say it's his second profession), and for many many years. There has been some footage of him during the early '70 Larzac protests (basically, HUGE protests against the extension of a nuke military base).
Oh, well, given the evolution of material engineering these last few decades (rougly -- since the JUMO-001D engine, whose operating conditions demanded a breakthrough in metallurgy to get reliable, which fortunately happened only long after WW2), it's not really difficult to do really better than in the past. Think about Cubic Boric Nitride coating on a high-tenacity polymetallic carbide compound, itself on a titanium substrate ; sounds cool to me.
Problem is, once you've slayed a thousand dragons or two, you'll need to re-coat your blade. Perhaps skip the traditional blade, and put removable CBN coated cutting units, instead (trouble is, how do you determine chip breaker geometry with a sword held by a dragonslayer ?)
Well, first, there are a lot of times it *is* desirable to not be uniquely identified (I'm sure those people in the early fourties who got tattoed their "GUID" on the forearm would agree. And that very same period would teach you how quickly a rather democratic (even if crippled) government can turn into one of the worst dictatorships mankind has ever known).
However, you can be almost uniquely identified by better than your SSN: {Name, Surname, Date and Place of Birth} gives you an almost unique combination. Better, there is enough room here for typos, which will hamper a database's ability to reliably collate data, but not a human's : this way, if someone really needs to ID you, it's possible, if it's just some greedy megacorp, they can.
I'm glad I live in a country where the SSN is protected (for how long ? Now the taxes can cross their tables with the (overdeveloped) welfare system:-( )...
Simple: you don't teach, or lecture this opinion. And you don't print it in publically-available media. Otherwise, there's no thought-police, and as long as it's in a private discussion, you can say what you want (and turning in people for a felony or a crime *is* a felony, unless the authorities specifically asked for hints ; so, normally, you can talk).
Yes, this sounds like a restriction on free speech. Here, before "Liberté, Egalité, Fraternité", we have "l'Ordre Public" to protect and keep untroubled. In the spirit of law, public order is a prerequisite to everyone's enjoyment of one's individual freedom. However, incitation to racial hatred, or negationism are deemed (by the law) as having enough potential to overturn public order, thus harming everyone's freedom. That's why the freedom of some right-wing extremist has to be restricted a bit (according to the law).
You might want to babblefish some stuff at http://www.legifrance.gouv.fr for more info...
You have the right to believe what you want (it's not Orwell-land here, you know !). However, there are some very specific beliefs and behaviour (namely, Negationism (negating the Holocaust), and all incitation to Racial Hatred) which are totally forbidden *to* *advocate*.
In Yahoo!'s case (which, overall, I find pretty moronic), what's been alledged is that selling these items is advocating racial hatred. (OTOH, you can buy as many books and stuff from that period, such as Nazi (and marechalist) youth magazines or photographs or whatever, on the Seine's upper right bank old book markets).
Have a look at stereolithography and other rapid prototyping processes ! This kind of technology has been out for ages (still a bit too expensive ; I wanted to have the technical high school I work for, buy one, so that at least *some* CAD exercises could be made matter), and still evolves very very very rapidly. Attend any big CAD trade show in your area, you'll probably see some RP in action..
Though it's quite imperfect, have a look at http://www.machpro.fr (also in English) for some links & contacts on RP hardware providers (and many other processes, by the way).
Nope. The batteries are going to be a leeeetle bit stronger (see, when in startup phase, you have the electric engine *both* accumulating enthalpy (for the termal engine) and carrying the car). Besides, if the battery falls below a certain thresold, the computer just won't let the thermal engine stop.
That's going to sound a bit funny with a rea^Wmechanical gearbox, but I can't wait to get such a car.
Subject says all ; their prototype "camless" engine is already running. Basically, they use electric actuators instead of the usual cams. And since the engine's electronic already handles fuel injection and air intake... it's just one more parameter.
Camless engines are routinely used in economy races such as the Shell marathon (run as long as you can, with a single litre of gasoline)...
What's going to really rock is HDi (or GDi) + Camless + alternatmotor (basically, you replace the smaller alternator + starter combination by a bigger dual-use electric engine/alternator, which allows to give the thermic motor a boost when accelerating, allows stop-and-go when you're stuck on the Périph's monster traffic jams (zero emission, then, and zero noise). Unfortunately, that means switching the car's electric circuit to 48V at least).
And that's going to be much sooner than 2007 !
(Besides, Diesel in HDi + Anti-Particle Filter is much more efficient than classic unleaded ; Diesel is easier to refine, and gives a little more energy per mass unit. And direct injection gives the level of control necessary. See whan Peugeot does with Bosch injectors, it's just really amazing).

Camless engines are routinely used in economy races such as the Shell marathon (run as long as you can, with a single litre of gasoline)...
What's going to really rock is HDi (or GDi) + Camless + alternatmotor (basically, you replace the smaller alternator + starter combination by a bigger dual-use electric engine/alternator, which allows to give the thermic motor a boost when accelerating, allows stop-and-go when you're stuck on the Périph's monster traffic jams (zero emission, then, and zero noise). Unfortunately, that means switching the car's electric circuit to 48V at least).
And that's going to be much sooner than 2007 !
(Besides, Diesel in HDi + Anti-Particle Filter is much more efficient than classic unleaded ; Diesel is easier to refine, and gives a little more energy per mass unit. And direct injection gives the level of control necessary. See whan Peugeot does with Bosch injectors, it's just really amazing).
