That he even mentions Fortran suggests that he is into heavy numerical computing. For that Fortran still is the language of choice for many, followed by C and C++.
There is quite some variation. We are still waiting for the fusion reactors. In regards to the computers, it all depends on what you mean by initial lab stages and general practice. If you consider Babbage's difference engine (proposed 1822) as an initial lab stage and the availability of affordable computers for the masses (1970 sometime), the computers took 150 years.
The vast majority of the guns in Finland are hunting rifles, which are awkward to use when mugging someone and far from ideal in a gang war. A gun that is designed and bought to be used against people, will much more likely be used that way, than a gun that is made to shoot elks (mooses).
But I agree that a big part of the problem is, as you say, income inequality and poverty.
For neutral atoms you don't use a Penning trap. A penning trap is for charged particles. For neutral atoms, two coils in anti-helmholtz configuration and six laser beams is what you need. Don't understand what you mean by "any visible object". It certainly is possible to view the cloud of atoms trapped and cold in such a trap, called a MOT (Magneto Optical Trap). The atoms scatters a lot of light.
Maybe, and maybe hopefully, slashdot will be like that again when more of the common people move over to sites like digg. I absolutly do not mind them being here, there is a lot of subjects discuss here about things that I am far from an expert in. I would not mind if the discussions were on a slightly higher level. If the submissions are a little bit above my head, I learn more from the following discussions and gain from the huge amount of collected knowledge in the slash-community. The knowledgeable people are still here, they are just drowned by the noise.
Not what I know of. Rb87, the most popular isotope used in these experiments is slightly radioactive, but the halflife is too long to make any difference.
Identical means the same isotope and same charge. Also only neutral atoms since any charge would make it very hard to achieve the density needed to achieve BEC (ions repel each other, you know). I don't think there is any BEC with ions.
Mostly alkali atoms have been used (the ones leftmost in the periodic table). These are the ones most straightforward to cool with lasers. They have also made BEC with spin polarized He. And yes, BECs with moleculs have been made. But I think the detection of these BECs are indirect. Usually, a BEC with atoms are made and then through manipulating the scattering length (the interaction between the atoms) with a magnetic field (Feschbach resonances) a molecular BEC is made.
If this answer is incomprehensible, it might be because it is Saturday night here and we are having a great party. I am a little (just a little) drunk right know;-). (WTF am I doing on slashdot.)
Being in a BEC does not halt radioactive decay. I don't see why it should.
Radioactive decay does affect a BEC. Firstly, it frees energy that will heat the BEC. A BEC of atoms is so cold that even recoils from (ordinary light) photons destroys it, then imaging what the recoils from the decay would do. Secondly, a BEC can only consist of identical particles. Emitting a alpha or beta particle leaves you with an other species and this can no longer be part of the BEC.
I am a Ph.D. student actually working with BECs so I should know what I am talking about. I am not as confident expressing my thoughts in english, so sorry for any confusion I might cause.
I think this hurts the party that was hacked more than the hackers. Of course I don't anyone as stupid as using "sigge" as a password to rule my country. Nowadays it is no excuse to be that computer illiterate.
Calling any of the four major right wing parties in Sweden racists is just bullshit. I can't believe this post is moderated informative. Even though they are proposing that immigrants should be required to take part in swedish education to benefit from the full social service, they are not against immigration. And certainly not racists! It was the left wing in sweden that warned about "social tourism" a few years back.
I'll actually vote for a left wing party september 17, but I can not stand see such nonsense as in grimmJesters post.
I learned Simula in my first OO-programming course at Stockholm University (Sweden) in 94. I was told that it had been used by several big companies (the one I remember is SAAB) at least in Sweden. It is a quite nice language, something like an OO-Pascal (have never tried delphi).
This year they will share 10,000,000 SEK, that is approx 1,300,000 USD or 1,100,000 EUR. Except from that they will get a medal presented by the Swedish king.
When you say that something is intended you imply that it is intended by someone. Who is that?
You cannot mean god. I am sure that every child that is born is according to his will and he equips them as he likes.
Genes don't intend anything at all, even if you can get that impression from some popular scientific litterature. If it never arised anything new there would be no evolution.
Like the four arms. If it really was beneficial it would be an evolutionary advantage and from the genes point of view it would be something good. (I know that I in some way make the same mistake mentioned above when I talk about the genes point of view, it's just so practical to express it that way).
Maybe in 30 years it will be very popular to be homosexual. They might hate you for fixing them.
Is it the disease that made them great? Otherwise the argument is faulty. The same proportion of healthy people are significant as among them with deseases. Think of all the great healthy geniuses that will not be born because we choose to give birth to an unscreaned child with the possibility of predisposition towards certain diseases.
(I hope that makes sence. I can garantee the thought was good. I am a bit crippled by my bad english)
Why does it make a difference if homosexuality is genetic or not? That is something I just can't understand. For example, there are theories that it can be genetically beneficial to not get any offspring under some circumstances and rather help rise your nephews.
I don't believe in that one. But what makes a gene that is against the norm a defect? Extreme intelligens is against the norm. Is that too a defect?

The security guards in the Westwood Mall (Durban, South Africa), uses them. I guess they are excellent for patrolling the mall and the parking lots.
sigh...
I'm capped at 1GB, then $7 per GB after that.
I should mention that I live in Durban, South Africa.
A pleasure to put together the media.

When they finally have something to sell, all the relevant papers have been written a long time ago.
Everything tastes like chicken in a first order approximation.
hmm, I would have written p:s in that case. Like in CPU:s or AOM:s.
Semiconductors, nuclear power and antibiotics. Just to mention some that I think have had some impact.

Thought it was three in the evening, not four.
Oh, yeah? Well, I have "The Computer Survival Handbook (how to talk back to your computer)" by Susan Wooldridge & Keith London, © 1973, hardcover. So neener neener neer! I beat that with James Martins's "Programming Real-Time Computer Systems" from 1965.
You are correct. The scattered light is blue shifted due to the energy it takes away.
