I don't think your argument that the American system is more convenient to live in holds. If you talk to people who grew up outside of the US (like me, for example) you will find that they can think as easily in Centigrades and cm as an USAian can think in inches and Fahrenheit. For example, you wouldn't talk about a 2/3m door, but a 70cm door, and people tend to think of room temperature as 20C or 22C. I travel back and forth between Europe and the US quite often and I do not find any practical difference between both systems. I think you're spot on with your argument why metric hasn't taken over yet. It's one of the idiosyncracies of the US system that are very difficult to understand for people from the outside (others are, e.g., the electoral system, discussions on gun control, etc.)...

I have yet to see an air based heating system in Europe. In Germany, virtually all heating systems are water based. The renewable energy used to make power in Germany is not only solar but also wind based. Plus there are backup sources (e.g., water based power plants). And, adding to that an infrastructure that actually works. I live in Germany, my significant other in the US. In the past seven years I had a few seconds of power outage TOTAL. My significant other had more than one week this year alone.

But the point is, the occurrence of an earthquake was very improbable. This fact is not changed even by the occurrence of an earthquake shortly after.

What the scientists were asked to do is effectively the same as predicting who would win the lottery. This is just not possible - even if somebody still wins it every few weeks...

I work with people from INAF (the national astronomy institute), ASI (the space agency), INFN (the nuclear physics institute), and several universities (Milan, Catania, Roma, Palermo, and others). For none of them your statements are correct, most of them (in their 40s) have around 100-150 refereed publications.

I am not going to name names on slashdot, but I really think that discussions should be based on facts and not on unfunded allegations as the ones you are bringing up here. It is not the people that are the problem, it is the system in Italy - as also evidenced by this very, very unfortunate court decision today.

Well, I know that this is flamebait, but still...

I work quite a lot with scientists from Italy in my area (astrophysics). They are among the most dedicated scientists I know and are doing world leading science. They are also among the least well paid - which shows their dedication to science.

The former Italian government (under Berlusconi) tried for years to marginalize science and research in Italy and this is yet another blow to the scientific system in Italy. The result will be disastrous and lead to an even larger brain drain of highly qualified people from Italy than what Italy has already experienced in the past 10-20 years. Everybody can imagine what this means for the long-term future of Italy as a place of innovation and science, which has already been damaged badly.

Comment Re:let's not waste significant digits! (Score 5, Informative) 182

This is correct. originally the AU was defined as the average distance between the Earth and the Sun. The problem then was to convert this distance to meters. The way to do this conversion in the end involves the product of the mass of the Sun and the Gravitational constant G. Both quantities are not well known (e.g., G is known to 4 or 5 digits only). But their product can be determined from modeling the motions in the Solar system to much higher precision. So by that time the AU was then redefined by defining the product GM (often called k^2, where k is called the "Gaussian gravitational constant"). It is my understanding that this has now been simplified. The difference between both is only a few meters.

No, this has nothing to do with JWST being over budget. The review concerns the astronomy funding through the National Science Foundation, whose budget is independent of NASA's funding. NASA funds all of space based astronomy (including data analysis), while NSF funds ground based astronomy. NSF mainly funds the national optical astronomy observatory on Kitt Peak in Arizona and the National Radio Astronomy Observatory in Charlottesville, VA, with facilities in West Virginia and in New Mexico (plus some other states). In addition, NSF funds data analysis/theory grants. Overall, NSF's budget is much smaller than NASA's, but then, ground based hardware is much cheaper than space based. To put things in perspective: for about 50% of all university astronomers, NSF facilities are the only way to get optical observing time (the remainder of astronomers have access via privately funded telescopes, such as the Keck). The closures of the instruments proposed in the report to NSF essentially mean the US giving up its current leadership in large areas of radio astronomy, and significantly reducing access to medium sized facilities for optical astronomers, if the (realistic) flat budget for the astronomy program is realized.

Comment Re:What the hell are they playing at? (Score 4, Informative) 176

I would assume that it is something similar to what NASA did with the ESA L-class missions last year, where they also pulled out and then held scientific workshops. NASA's problem is that it has no money to participate in ExoMars or the L-class missions, and that's why they pulled out of ExoMars. However, legally speaking NASA is required to follow the decadal reports, and the planetary one recommend Mars research. This then led to the schizophrenic situation that they have held workshops for ideas on how to do gravitational wave research (LISA), X-ray astronomy (IXO), and now apparently Mars, where they previously pulled out of all joint ventures with ESA and JAXA. However, the good thing is that with the recommendation from the decadal reports and the results from such workshops the scientists at NASA headquarters have an argument that spending some money for R&D in these areas is necessary, because they can prove need. As a result this important research does not die. There is money for general R&D in the budget, so while some larger programs have been explicitly canceled by either OMB or congress, the Mars/X-ray/gravitational wave research can at least be partially funded this way.

I'd not blame NASA for this but rather congress, which tends to try to exert strong control over NASA, which in many areas really amounts to micro-managing projects, without Congress really understanding what it is doing...

This comment is probably a good explanation why journalism in the US, and therefore also the newspapers in the US, are in such big trouble - that most people think it is the opinion page of a newspaper that matters, rather than the information provided by a newspaper.
What I want in journalists is to select the information that is relevant for me. The NYT does this rather well, as do other newspapers such as the Economist and the Guardian in the UK, Spiegel, FAZ and the Sueddeutsche in Germany, or Le Monde in France. In my opinion, this unbiased selection of information is the main job of journalists - people still can do such a selection much better than automated searches. For that reason, I couldn't care less about the opinion or comments pages, although it is usually these pages that people mainly talk about. I mean, shouldn't educated users be able to form their own opinions based on the available information? If that's the case, and I believe it is, shouldn't one read the newspaper that provides the best selection of such information available, regardless of the (unimportant) opinion section?

Sorry, while I agree with your programming statement, please be aware that with antilock brakes in most situations the stopping distance is decreased, not increased as you claim (see, e.g., http://www.abs-education.org/faqs/faqindex.htm). The reason is that usually you have better traction when your wheels are rolling, not when they're blocked. It is only in very rare situations that you'd be better off without ABS. So you want ABS even for good drivers since as a human you just aren't fast enough to modify the braking force on the wheels to keep them from blocking.
