From what I've read, that number is right, but it's because of additional restrictions. For example, there are restrictions on visible tattoos:

IIRC, all people who need to take medication every day are also out. (I know that I'm out for medical reasons, even though I could handle those physical requirements.)

All the restrictions put together really limits the eligible pool.

it simply reserved such matters to the States, per the 10th Amendment.

I'm not sure how 'not forbidding' is different than 'allowing'. Regardless, slavery wasn't handled just through the 10th amendment. Article 1, Section 2, Paragraph 3 specifies that slaves (i.e. people who are neither free nor indianans) count as 0.6 people for determining the number of congressional representatives from a state. Because of that, I'd say that the constitution condoned slavery.

I'm surprised the "dominating group" is that large. There aren't a ton of _senior_ scientist out there (i.e. professors or researchers with the funding for graduate students and postdocs), and those are the people whose names appear most frequently. A senior scientist will probably have been doing research for years, have lots of projects going on at once, have many students and postdocs, have a number of collaborators, and the senior scientist's name will go on every paper produced by that group (even if it's as a middle author -- which means next to nothing). New guys will often want to collaborate with the big names, which means the big names get on even more papers. If you're working on your own (i.e. you don't have the funding to hire others), then you won't publish as frequently.

What did you expect? Why is this an issue?

Sincerely,

A graduate student who has been working on a project for two years (and who should be working on a paper)

In all these years, nobody has rear-ended me in the dark. Even if the back lights of my car doesn't blink.

That's not a fair comparison; a car has large taillights, but most bike tail lights are low-power LEDs.

Are you mad when car turn signals blink? Even brake lights turn on and off in an attempted to get people's attention.

Maybe blinking bike lights don't help. Maybe they don't. You raise an interesting question, but your thoughts and anecdotal evidence don't contribute much. There are some actual studies out there, and they seem to indicate that blinking lights are more effective. (This has a number of references.)

Just a thought (unsubstantiated): a blinking light may help differentiate a bike from other vehicles, and that may be useful. if there's just one bike and one car on a street, then that isn't an issue. If a cyclists is on a road with many cars -- all with steady red lights -- then it may be hard to recognize that there's a cyclist in the mix. A blinking light could make it easier to tell that there's a non-car on the road.

Do you really think these idiot cyclists don't know what a red light means? They know; they just don't care. A license would not fix that. (Altho it may make the idiots easier to fine.)

It's not like drivers really know the laws relating to cyclists either, and there are some unexpected laws (example). That said, I'm fine with cyclists having to get a license -- as long as drivers have to pass a rigorous test of laws related to bikes...

and oh by the way photons can momentarily turn into other shit on their journeys yet somehow neutrinos can't.

I don't study particle physics, but from what I understand, for photons or neutrinos to "turn into other shit", they need to interact with something -- such as the particles they create, atomic nuclei, etc. Photons interact through electromagnetic forces -- which is the strongest force out there. In contrast, neutrinos interact via the weak force. As you might guess, that force is very weak. That's why neutrinos are so hard to detect.

Since photons interact with "other shit" via a much stronger force than neutrinos, photons are much, much, much more likely to "turn into other shit" than neutrinos are.

So, sorry internet troll, this isn't "cherry picking"; it's science. Deal with it.

WRT the Black Hawks, I'd say that up to the Sauk, since Black Hawk was their leader at one point.

They wouldn't necessarily object. For example, the Seminoles officially sanction Florida State University's use of their name. Having a sport's team named after you needn't be insulting; since sports teams emphasize hard work and skill, some take the naming as an honor.

However most Native Americans object to "Redskin" -- which I can certainly see as being interpreted as an insult.

The TV example is a mix of proving his point and a meaningless comparison.

Digital generally has two states: working and not working, and GP is saying that it's often easy for an all digital system to be in the former camp. (Think of an LCD computer display that gets digital inputs; there's almost no noise there.). However, "Digital" TV is really a digital/analog hybrid: you have analog antennas, amplifiers, and filters. Those analog parts are flexible; the digital part is much less so. The analog part can take some noise (snow on an analog TV), but when that noise is passed on to the digital part, things can fall apart. I.e. digital signals are much more sensitive to GIGO (garbage in, garbage out), but that's much less of a problem on an all digital system.

In short, the complicated part is the analog part; if that can give the digital part a good signal, then there are no problems. In other words, it's exactly what the GP said.

Interestingly, I had metal shop in middle school, but not high school. (The middle school building used to be the high school, and the new high school didn't get a metal shop, although it did have other shops.) Whoever decided to let middle schoolers weld was crazy, but in a good way. It should definitely be available in high school.

I'm a physics grad student now, and I've used the student shop here to make custom parts -- in part because the real machinists in the instrument shop have a several month backlog. I guess that's inline with the article's claim. I've got a ton of respect for the machinists here: it requires lots of skill and problem solving abilities; it's not easy to make the crazy stuff we want. In short, their jobs aren't in danger of automation, and apparently there's demand for them. The same cannot be said for communications and journalism majors...

Hold the phone. You're assuming all of this is public work. There are 12k somethings that haven't been released. What are they? Papers? Emails? Datasets? TFA doesn't say, and you don't know what they are either.

If they're his emails, then they are not public work and should not be released. Full Stop.

If they're papers, then a case can be made that they should be released. That said, all researches have work that isn't for public consumption. I'm a researcher at a public university. Do I have to publish my notebooks? How about every little piece of test code I write? What about works in progress? Some of the "papers" mentioned probably fall into these categories.

Without more information on what hasn't been released, we can't yet draw conclusions .
