But the research done so far has generally found that seatbelts would do minimal good, that the harm they would do might be greater and that the cost of installing them would be high. The National Transportation Safety Board has not put train railroad seatbelts on its “Most Wanted List” of safety improvements.
“It’s been asked frequently, and honestly I remain uncertain, but the conclusion has always been that you can’t justify it,” said Steven R. Ditmeyer, a former director of research and research development at the Federal Railroad Administration.
Experts say they do not know of any country that has rail passengers strapped in.

Vested interests and political agents have long opposed political or regulatory action in response to climate change by appealing to scientific uncertainty. Here we examine the effect of such contrarian talking points on the scientific community itself. We show that although scientists are trained in dealing with uncertainty, there are several psychological reasons why scientists may nevertheless be susceptible to uncertainty-based argumentation, even when scientists recognize those arguments as false and are actively rebutting them. Specifically, we show that prolonged stereotype threat, pluralistic ignorance, and a form of projection (the third-person effect) may cause scientists to take positions that they would be less likely to take in the absence of outspoken public opposition. We illustrate the consequences of seepage from public debate into the scientific process with a case study involving the interpretation of temperature trends from the last 15 years. We offer ways in which the scientific community can detect and avoid such inadvertent seepage.
And you might have thought the American for-profit schools that encourage debt and underproduce evil...
At first glance, Axact’s universities and high schools are linked only by superficial similarities: slick websites, toll-free American contact numbers and calculatedly familiar-sounding names, like Barkley, Columbiana and Mount Lincoln.
But other clues signal common ownership. Many sites link to the same fictitious accreditation bodies and have identical graphics, such as a floating green window with an image of a headset-wearing woman who invites customers to chat.
There are technical commonalities, too: identical blocks of customized coding, and the fact that a vast majority route their traffic through two computer servers run by companies registered in Cyprus and Latvia.
Five former employees confirmed many of these sites as in-house creations of Axact, where executives treat the online schools as lucrative brands to be meticulously created and forcefully marketed, frequently through deception.
But these explicit attributes only scratch the surface. The online ad giant knows much more about you than it can put into a form easily understandable by humans. Just how much it knows came to light last year, when a Federal judge ordered the publication of some remarkable internal Google emails discussing how Gmail data mining works. Google’s lawyers fought the disclosure tooth and nail, but they were ultimately overruled. The emails reveal that Gmail can sort users not just into a few thousand demographic and interest categories, but into literally millions of distinct “buckets”. A “bucket” is just a cluster of users, however small, who share some feature in common that might interest advertisers.
There are a lot of reasons for using a good stand-alone camera over the one in your smartphone, but for most people the one they're always carrying that makes images and video easy to post online is adequate. Plus they happen to be getting better. Big improvements coming in the next generation or two. Apple filed patents suggesting a three sensor camera using dichroic mirrors a periscope like optical path in the camera body. They should be able to use a larger lens for low light capability, have better focus control and much better color quality and control with three physically separate sensors. They also bought a company that is going multiple sensor/lens image synthesis which could have separate uses, but would make manufacturing the three sensor camera less expensive. Their competition must be working on similar projects - all of this is sort of obvious next step work.
Results in the hands of professionals are impressive. There have been some wonderful smartphone based still images - much better than I could ever hope to take. The cameras are good enough that they aren’t professionally embarrassing and their lack of flexibility is seen as a plus by some. Recently John Lasseter said that serious film story telling was going to happen on GoPro and iPhones. I would agree, but note the GoPro is really a specialist camera. I doubt it will see much further growth.
Here’s an example of a video Bentley commissioned. They “cheat” and use a steadicam , an accessory lens, and a real microphone but the software is $5 to $10 and you can rent the kit. All you need is the skill:-) There are teens that could pull this off. The really good ones may even graduate to professional tools for greater control and creativity, but the gap to what is good enough continues to shrink.
and how they made the video (it also mentions an earlier one made with a last generation camera)

We’ve arranged a society on science and technology in which nobody understands anything about science and technology, and this combustible mixture of ignorance and power sooner or later is going to blow up in our faces. I mean, who is running the science and technology in a democracy if the people don’t know anything about it.
