Comment Re:30 day suspension of pilot's license for prev. (Score 1) 271

I don't believe you actually need a pilot's license to fly anything characterized as an "ultralight" aircraft, as these tape-and-balsawood gyrocopters appear to be. Doesn't mean the FAA can't fine your ass, of course, when you do dumb crap like flying a possibly deadly set of large rotors right past crowds of tourists at low altitudes in an urban area like DC.

Affects child development. The pattern looks like autism, but nobody's drawn that conclusion; what they have concluded is that electronic devices are more interesting to children than the real world, and cause them to develop emotionally stunted, withdrawn, and more interested in things than people. It's notable you can identify an autistic infant by watching if it's interested in human faces or in objects.

So, yeah. Interactive electronic devices, TVs with robust entertainment content, and so forth draw the attention of children and disrupt their social development. It's believed a similar, but weaker, effect occurs on adults. This is generally framed as "electronic screens are bad", and I don't feel like typing out term papers about what's actually being said because I like to take science for what it is: a pile of important data that must be analyzed for subtle patterns to derive better conclusions on one side, and a simple and complete conclusion useful to engineers but useless to scientists on the other.

You can debate the science if you want, but it's out there, and people have used it to engineer systems of education and general guidelines for the upbringing of children. Such engineered guidelines haven't been scrutinized as scientific principles, but neither has a Boeng 747.

Yeah, the hypothesis phase is the start of the scientific method, and it involves intuition and making shit up.

It's more like having the scientific understanding of how lithium ion polymers behave with regard to electron potential creation, and how electrolytic solutions work, and then selecting an electrolytic solution and a lithium ion polymer and putting them together to build a battery. At the end of the day, you've done some work, taken some measurements, made some tweaks, gotten consistent results, patented your Li-Polymer cell, and started manufacturing and selling it in products; it works; but you haven't gotten any science down saying it works the way you believe it works. All you can do is spout about the science that you had for precursor, the things you slapped together, and the results you got.

This might surprise you, but a lot of things are held on the thin branch of slapping a bunch of well-understood science together. Many drug treatments, for example, are held together by science that says certain biochemical effects are useful in a certain way, and science that shows the drug has those effects; we often come back with the conclusion that an entire class of drugs with a long history and variants both ancient and modern are actually totally ineffective because of this.

To put this into context: we have hard science showing that exposing kids to electronic screens is bad. Science backs up that exposing children to electronic screens is bad. We don't have science examining, say, Waldorf Education, which avoids exposing children to electronic screens until they're like 7-8 years old, against new-fangled high-tech Apple Elementary School with iPads all over the place. We've looked at scientific evidence showing that exposure to electronic screens is harmful to child development and determined that a school of education should avoid doing exactly that, in the same way that we've looked at science suggesting antimony should not be in a child's diet in significant quantities and concluded that diets without antimony are better for kids than diets with antimony.
