Comment Ozone is ozone is ozone... (Score 2) 30

...there are not "two forms of it", its the same molecule (O3), just in different layers of the atmosphere. Down in the troposphere we breathe it in - and it is an extremely aggressive gas, so at non-trivial amounts it damages our lungs. Up in the stratosphere we would die a lot quicker from lack of oxygen...

Comment Re: Personal Responsibility Be Damned (Score 1) 282

It's a private bridge on a private road. That makes it harder to blame "the authorities". The road also was partially overgrown on at least one side of the road - check the images in the linked article or at the Washington Post article. A lot of things came together, but a responsible driver would not have had the accident. On the other hand, there should have been warning signs and/or barricades. The family has my sympathy, but that does not affect who is to be held at blame.

At optimum theoretical efficiency and an environmental temperature of 20 degree C, to reach 80% efficiency, it would need a working gas temperature of 1456K, or 1192 degree C. Aluminium melts at 660.3 degree C Steel actually remains solid up to 140 degree C or so, but it loses a lot of its structural strength at around 600 degree C. So I assume they need to use Neutronium or something like that...

Comment Don't use a hammer as a screwdriver... (Score 1) 293

Scrum has strength and weaknesses, and it's good for some situation, not for others. But what I see most often is "Scrum" instead of Scrum - they do all the meetings, but don't give the developers control over the backlog. Instead, some unholy trinity of Scrum Master, Product Owner, and Project Manager try to boss the coders around, often with little understanding of either the project goals or the technical foundations. Of course that fails... If you want to use Scrum, the whole team needs to understand the objectives, and the people who understand the technical foundation need to decide on expected cost. The Scrum Master needs to keep other managers of the developers back, and avoid interference with technical decisions. In that case, and if you have a shallow and broad project (where you can easily decouple requirements), Scrum is quite good.

Comment Re:Oh yes. Great, cheap, fast to build nuclear... (Score 1) 41

I've always said that it is possible to build a really solid and safe nuc reactor power system. Just not by humans.

Even if, it seems that without massive subsidies (because that is what the "tax breaks" are) no-one can build a nuclear reactor that is actually financially viable.

Soviet socialism worked for a while. What killed it was criminal corruption. Most of Europe is socialist today - capitalist socialism - it mostly works. The places where it doesn’t, it is likewise due to criminal corruption.

It's extremely hard to disentangle the various historical influences - and it's similarly hard to even agree on a terminology. In the case of the Soviet Union, it started literally during Russia losing the first World War - about the first thing the new Bolshevik government had to do was to sign the extremely damaging Treaty of Brest-Litovsk, basically breaking apart the Russian Empire (it lost about 1/3rd of its population, and much higher percentages of industrial and agriculturally productive lands). After WW1, it was ravaged by civil and quasi-civil wars, with most of the world's major powers supporting the "Whites", i.e. the (from the Bolshevik side) insurrectionists. Only 18 years after the end of the Russian Civil War, the Nazis attacked the USSR, devastating much of the most productive areas again. And after WW2 was won, the Soviet Union was in immediate conflict with the Western powers (which had suffered much less during the war - especially the US, whose heartland was essentially untouched by the war. We just don't know how a Socialist Russia would have done under different circumstances.

And let's not forget Sputnik, Gagarin, and the fact that until a couple of years ago Western astronauts flew to the ISS in Sojus spacecraft.

As for terminology: Socialism is formally an economic system in which the means of production are controlled by society (i.e. in practice by the state). Capitalism is an economic system in which the means of production are controlled privately. Neither of these definitions directly mention democracy or human rights. Few states practice either socialism or capitalism in any pure form, and both have been combined with very different systems of government.

And no, capitalism is not only about "owning ones own property". A very basic principle that made capitalism in the modern sense possible is the limited liability corporation (in various forms). It enables people to limit their risk when investing - but of course eventual losses if the company fails will have to be picked up by someone, often society. Imagine a privately owned garbage dump going out of business. There will still be a steaming heap of garbage that needs to be managed (or it will pollute water and air, be a fire risk, and litter much of the surroundings). This becomes even more obvious if it's not a normal garbage dump, but a nuclear waste facility...

I don't think we are talking about a rip of your parents 1980s VHS copy of Story of O, or the fuzzy 8mm documentary from that nudist camp. Think fully immersive 3D role playing games - not recored, but rendered live. With virtual full-body overlays for you and your partner(s) - wether you want to play out Beauty and the Beast, Emperor Ming vs. Dale Arden, or Patroklos and Achilles is up to you.

The population freaked out and voted for more Green Party representatives after Fukushima.

Actually, the conservative/liberal coalition under Christian Democratic chancellor Angela Merkel (who, btw, holds a PhD in physical chemistry) voted to (again) phase out nuclear power after Fukushima in 2011. We had a much more organised (and cheaper) phase-out agreement since 2002, negotiated under the red/green coalition, but that had effectively been cancelled by the Merkel government in 2010.

Under the current phase-out agreement, the last power plants should have shut down last year, but then got one last extension due to the Ukraine crisis (as it turned out, they would not have been needed, but the government was cautious). That some politicians are yelping now is simple populistic posturing. The nuclear industry has begun shutting-down over the past years. Retiring staff has not been replaced, new staff has not been trained, mandatory safety inspections and repairs have been skipped under special end-of-life exemptions, the installed fuel elements are spent and no new ones have been ordered (nor are even available on short notice), and so on.

Please educate us: how is the sea level at Shanghai higher than everywhere else?

The ocean is not a static body of homogenous fluid, but rather a dynamic system of intermixing (but not perfectly mixed) different fluids. Both different densities (e.g. less saline or warmer water in some regions) and changing currents can lead to differences in sea level and differences in sea level rise.
