Good point – but in fact a dictionary does show about half a dozen meanings for "theory", one of which is a synonym for hypothesis.

It's a real problem that many people seem to think that "theory" has only that one meaning, and don't understand that in science it more often means an established body of knowledge generally derived from a number of well-verified hypotheses.

Another analysis might be that gun control laws are introduced in places that have problems with guns. There's room for any amount of discussion about why problems arise in some places but not others, but clearly the situation is very different in different parts of the country. It has also been noted that places with relaxed gun control laws are a significant source of the guns used to commit murders elsewhere. Why would you enact strict laws if you didn't have problems and your economy benefited from the sale of guns?

It's very similar to the problem of the single currency in the Euro zone preventing local economies from using monetary policy to deal with local problems.

It's nice to have a couple of large files open side by side sometimes. When I have a lot of windows open at the same time I prefer to have them side by side rather than stacked vertically. As long as I have enough vertical pixels, lots of horizontal pixels are nice too. At the moment I kind of like 16:10 because 1920:1200 is the widest screen I can get for a reasonable price with 1200 vertical pixels.

Depends. You don't have to hit 1000 people on the thumb with a hammer to conclude that some people sustain damage when hit on the thumb with a hammer.

If you're trying to find correlations between events in a complex situation where you can't directly observe the relationship, large samples are necessary. If you give someone a radioactive tracer and track it with suitable instrumentation, you can figure out where that pill went without trying it out on 999 more people.

A bit simple minded.
Capitalism is a system with several distinct components. Investment is a process whereby wealth is accumulated and used to develop mines, factories and the like which in turn create more wealth. Finance is the operation of banks and other institutions to move money from place to place. Markets are places, real or virtual, where goods are traded or exchanged for money. Markets, mines, factories and banks all existed long before Adam Smith developed his theories about them.
Over the last couple of centuries we have (at least in theory) had a system called Free Market Capitalism. A market system may be considered free when it is not unduly controlled by governments or monopolies. We have also been rather keen on Free Enterprise, which means mines, factories and so on are privately owned and operated in a manner reasonably free of government interference. We do, however expect a system of laws governing contracts to enforce repayment of loans and delivery of goods that have been sold. There may even be laws holding mine and factory owners liable when they kill or poison their workers, although there are certainly those who regard this as undesirable interference.
Too Big to Fail generally means we're in a situation where owners no longer suffer the consequences of failure as they are assumed to do in Free Market Capitalism. We the people didn't get a voice in how they were run, but we're supposed to bail them out.
The stock market is the interface between Finance and Investment. It is indeed part of the capitalist system as we know it. If you buy shares in a limited liability company, you're putting your money at risk, hoping the operations of the company will be profitable. However, if you're just looking for a quick return in the short term, you probably don't care if the company is successful in the long term. You may pressure the directors to go for short-term profits to drive the share price up so you can sell your shares at a profit, leaving someone else holding shares that will lose their value when the short-sighted decisions lead to problems.
The stock market is not necessarily good for the long term health of the economy.
If companies are owned by people who have their own money invested, they will probably be managed for a balance of short and long term returns. If companies are run by managers who are trying to attract the interest of day-traders, then main street may very well suffer.
Capitalism requires companies to be able to raise money through investment in shares, but there's no guarantee that stock markets will operate in a way that leads to a healthy capitalist economy.

Do you think it would be a good idea to remove some regulation from government, as well as from private industry? Of course we're all supposed to be afraid that would lead to massive waste, but that's what we achieve with over regulation anyway.

Hugh Pickens writes writes "Talk about visualizations. Ever wondered what the wind would look like if you could see it in action from above? A new project posted online by a pair of Google computer scientists, called simply Wind Map, has to be seen to be believed. "It can be quite hypnotizing to watch the gusty trails blast across the American continent, skitter over the Sierras, get roughed up by the Rockies, and whoosh over the great plains on its way to Canada," writes Chris Taylor. Wind Map is the brainchild of Fernanda Viégas and Martin Wattenberg, the co-leaders of Google’s “Big Picture” visualization research group in Cambridge, Mass. Wind patterns are constantly changing, of course, which is why the Wind Map designers have also given us a moving-image gallery of previous blustery days."

Sort of. But all data is not created equal. VoIP requires many small packets which consume more packet switching capacity than a smaller number of larger packets typical of other data. VoIP also typically requires higher QoS than other data. Of course that can all be swamped by streaming video.

What's to stop you using UTC in any situation where you think it's convenient? Why do the rest of us have to change? The relic of the past is separate time zones in every town. Standardizing that to a couple of dozen time zones plus Newfoundland stil leaves anomalies near the boundaries but it works well enough for people in most localities. Having the day change in the middle of the morning or afternoon would strike many people as a bit of an anomaly. It might be useful to give the UTC in parentheses after the local time for a few things like airline schedules. There are benefits to setting your watch to local times once you land, though. You have some idea how soon it's likely to get dark, when hotels are likely to let you check in or out, when restaurants are likely to be serving breakfast or lunch and so on. And you can leave the time on your phone set to UTC so you'll know when that conference call is -- or if you've given up wearing a watch, get a phone that's not too dumb to display local and UTC at the same time...

Anecdotal evidence can motivate scientific research.

Absolutely. And compilation and analysis of anecdotal evidence can lead to reasonable suggestions for modifying behavior even before there is a full understanding of the underlying mechanisms, trading off putative benefit of behavior change against cost of not doing so.

Besides, in this case, TFA quotes Boeing engineers demonstrating mechanisms by which the anecdotally described problems can be reproduced. In almost all serious accidents there are a number of factors, no single one of which would have caused the accident all by itself, although removing any single one of them might have been enough to prevent the accident.

were called computers. They were educated people who performed long, repetitive calculations such as artillery tables. Electronic computers were developed to do that work faster and more reliably.

There doesn't seem to be any fundamental reason that the power of machines to do both mechanical and information processing shouldn't be directed to providing leisure instead of increased production. In fact, the work week for some has come down from six or seven twelve hour days, which was quite common until about 100 years ago to five eight hour days now. Children from the age of five or six used to work those hours, often in dangerous jobs.

There have always been a few people who make a good deal of money from the output of both machines and other people. That money gives them a lot of influence, and they don't give up their profits willingly. Change requires society as a whole to focus on some paricular segment, to the point where it is impossible for even hired legislators to ignore it. That will be difficult, at least in the US, because FOX News does a brilliant job of persuading a sizable chunk of the population to blame and despise the victims.

Perhaps it would be easier to start by rallying sympathy for burger flippers and Walmart drudges, and maybe even teachers, than for lawyers, though.

Maybe the few genes that regulate the primitive behavior are simple and incapable of evolving, although it’s not clear why those genes would not mutate. TFA doesn’t give any reason to believe there is only one mechanism for suppressing them, or that it only has one mode of failure.

But really not the point.

As a lot of people have pointed out, flying is harder than driving. A roadable airplane would appeal to an existing market of licensed pilots. The concept of a flying car is that you trade in the clapped out Taurus and take off in your new whirlygig from the dealer's parking lot and somehow make your way home without making an appearance on the nightly news -- assuming that such mayhem had not become too commonplace to make the news any more.

This project actually expands the potential market a bit, since they've managed to get it certified as a Light Sport Aircraft (LSA). You only need a Sport Pilot license to fly it, and you can get one more easily (and cheaply) than a Private Pilot license. There are restrictions (only one passenger, no night flying, and don't go near the major airports, for example -- and even with a Private Pilot license, the restrictions apply because it's an LSA) but it would be great for recreational use.

You'd still have to keep the old Taurus on the road, because you certainly wouldn't want someone rendering your $100K LSA un-airworthy while you left it in the supermarket parking lot.

"Roadable" means you don't have to leave it at the airport, and if you run into bad weather you can land and drive home, and if you fly down to the airport near the beach, you can drive the rest of the way -- if you think it's safe to park it off the airport.

Taking an airplane and making it roadable may not seem like much of an idea if you were thinking of the Jetsons, but if you're already a pilot, or are thinking about becoming one, it's a pretty neat idea.
