  1. out of touch with reality on Lit Motors, Danny Kim, and Changing How Americans Drive · · Score: 1

    People may "commute" alone, but the primary reason for a car purchase is not the commute. We'd all be in smart cars and fiats if all that mattered was getting to work efficiently and staying out of the rain. I think they need to think a bit more about why people (ok, specifically americans) buy cars.

    Maybe it's only 20% of the time I need cargo space, passenger space or the ability to mount a child's car seat. The reality is, it's that 20% of the time (moving kids around, weekend trips, runs to the hardware store) that determines what kind of car I drive.

    Maybe there is an economic argument to be made for maintaining a second, extremely cheap to operate vehicle. That cost based argument fails here when you consider competing low cost options like a bicycle, electric scooter, bus or a carpool.

    Sure, they can release the details of that contract. Government contracts are supposed to be public. Go take a look at usaspending.gov and fpds.gov There are plenty of security contracts posted there, just not any between RSA and NSA. It's not the easiest system in the world to navigate, you have to know a lot about government contracting to make sense of it.

    But, you'll see military hardware contracts, homeland security database contracts, all of them are published on federal websites as a matter of course (you have to get special approval to not post a contract publically). The government mandates this so that competing companies and the public can see that they're getting a "fair deal". Never mind that a lot of these show they weren't competed, no one actually takes advantage of government transparency when it's available.

    Like everyone else looking at this, they assume we'll have to use a carbon nanotube tether. They propose a spun tether of nanotubes, but use the strength of individual nanotubes in their model. Nanotube yarn is about 1/10 the strength of the raw material (which is insufficient). Growing the raw material directly would only take a few thousands of years more than the four they plan on using.

  5. Re:Practicalities on Major Scientific Journal Publisher Requires Public Access To Data · · Score: 1

    We are paying for that access.

    I've been a government employee overseeing research grants. Nearly every single one of them has a clause built in that the data is to be organized and shared with the government and the government has unlimited rights to that data, including all publications. Almost all of them have to have a data management plan and have to describe how the grantee will ensure access to the data.

    Almost every single PI simply says "We will follow a standard data management plan." or some other nonsense. The government guys sign off on this, and that's that, there's no enforcement.

    When you buy or build equipment on a government grant, you sometimes have a choice to hang on to it or return it to the government at the end of the grant. By agreeing to be the custodian of that equipment, you agree to maintain it, free of charge, for the government. By law, no one gets ownership of free equipment from the government. The government is absolutely terrible at enforcing this.

    These legal documents researchers sign with the government have meaning. Read your contracts. That was the first thing I told my PIs. I don't think any of them did.

  6. Re: DOE is there for teachers, not students on Oklahoma Schools Required To Teach Students Personal Finance · · Score: 1

    It's a bit silly to equate communities setting their own standards to community members having no rights. Should standards be set by those outside of the community? Should Arizona education standards should be set by... Delaware? Even then, you and I would agree that we're all part of the same national (and global) community. The only way to have a standard is for some representative(s) of the community to set it.

    Some children will be poorly served by a communal standard, but that's part of living in a community. It's not about having rights or not. It's simply that not every group decision will be optimal for every individual in the group.

    I don't think JET ever reached Q of 1, but it can handle the most energy dense fuel of any current tokamak (The JET Q of 0.6 is still ~100x larger than NIF). However, a Japanese tokamak did reach Q of 1.25 in the mid 90s, and it wasn't something guys in the field I knew talked about as a problem by the late 90s.

    There's a big challenge in getting the energy out of a fusion reactor. There are parts of a reactor which need to collect energetic particles so they could even theoretically produce power. This screws with a lot of other things in the reactor; it's not easy. Magnetic guys have been at the stage of designing those parts for a while. Given their progress, they may never finish. But those problems are a lot closer to talking about "fusion energy" than what NIF does.

    A guy working on diverter physics for ITER *has* to wonder why NIF gets all this press, while no one cares about the work he does on designing the part which could actually demonstrate extracting energy from fusion.

    You're pointing to articles on high end mammalian brain structures when TFA is referring to the most basic structures in an insect brain. Also, this blanket assumption that no one could possibly understand the complexity of a small group of neurons is way out of date.

    Olfactory circuits are pretty well understood. This isn't the first simulation of neurons mimicking an olfactory bulb at the single neuron level. We've been watching videos and seeing presentations of these models for years now. What is neat, here, is that they're modeling a somewhat realistic hardware instantiation of a model (as in, this is something which maybe could be built).

    I come at this from the other end. I make the chemical sensing hardware that mimics the response of a biological chemical sensor (an artificial insect 'nose'). There are long running collaborations between my field and neuromorphic computing folks to develop a combined sensor-processor that can electronically understand smell in the same way a living thing does. I have to sit through their talks on modeling neurons, and they have to sit through my talks on nanosensor arrays.

    Does anything you brought up matter to the overall point that government is in the habit of breaking it's own laws?

    Fast and Furious lost "strength" as a scandal because gun walking was revealed to be a "standard" technique implemented at a local level. There's questionable legal and moral basis for this, regardless of whose fault it is politically. There's a big difference between something seen as a "fake scandal" and something which "didn't happen." Gun walking does happen and it shouldn't.

    It was still wrong for the IRS to delay applications the way they did; the IRS still insisted on information they weren't entitled to. The IRS did share information with people outside government that they shouldn't have. It's not ok that these things happened just because it hurt people evenly across the political spectrum.

    It's not ok for any president to ignore implementing a law. Does the fact that Bush's administration ignored environmental law make it ok that Obama's administration ignores the health care law? This doesn't make any sense. Can the next administration pick a new set of laws to ignore? It's silly. We don't want a system where that kind of behavior is ok.

    Your arguments are part of the problem here. (PART, not the whole problem, calm down...) We have to stop looking at things in terms of who is winning and losing politically. The root problem in our country is a pattern of poor governance. Regardless of who is in power, we need to expect and receive competent and ethical government. We are not getting that. (And the point of this discussion is that Christie is part of the problem, not the solution.)

    There were many moderate Republicans and Independent voters who recognized after Bush that the Republican party had "lost" the ability to effectively govern (I was one of them). There will be many moderate Democrats and Independents who now come to the same conclusion about the Democratic party.

    I've worked in the past as part of the DoD Acquisitions Workforce.

    CMMI is really just part of a broader obsession in DoD with project and program management. Abstractly, these are good things. When implemented correctly, they make debacles like healthcare.gov nearly impossible. Good planning, budgeting and in-progress evaluation are generally applicable to basic research projects, software development and building ships. We all want to work on projects which are well run.

    The problem is, blindly stepping through the predefined process of project management has nothing to do with actually managing a project. You still need good managers who can recognize problems in the technical fields they're working with, understand what to do when problems crop up and are empowered to act. DoD in general fools itself into thinking it has people like this because the paperwork is done right. I suspect that's a fairly common problem.

    We all know there's a problem with treating the "talent" (i.e. programmers) as interchangeable blocks using these systems. I think treating management the same way is worse. The ideas that management is mastery of a process and operates solely for organizational interest over individual interest are flawed, but central to things like CMMI.

    Our scientific research system is built around the process of joining a lab, mastering the work there, and then leaving. There are very few long term research partnerships. The people who stay in place are the professors, who generally do not do the research work.

    So you join a lab, produce a few terabytes of data a year, pull a few publishable nuggets out of that and then leave. I have a few backup hard drives that move around with me with what I consider my most important data, probably total 1/10 of the data I have taken. After a few years, this data is really unimportant to me as the labs I have left have done a good job of continuing the research and I have to spend my time and money on something else.

    (Why was a poorly written press release linked instead of the actual paper?)

    This paper shows how you can start with an extremely simple theory of electron interaction and build up to some very complicated, realistic superconducting behaviors. When varying the material properties of high temperature superconductors, you always see an antiferromagnetic material type near the superconducting material composition. For many years condensed matter physicists have suspected that this was more than a coincidence and that high temperature superconductors work because of finely tuned antiferromagnetic interactions between electrons. Although this paper simplifies electron interactions considerably (come on, we're physicists, simplification is what we do), it does fill in some of the larger holes in that theory and is an important step toward understanding the physics behind the phenomenological high temperature superconductivity models.

    I feel like the academic freedom comments are put out there mainly to try to get non-scientists at universities interested in this issue. To me, this is simply about spending tax dollars effectively. It does outrage me when I see a professor getting a big government R&D contract to research something I've already done, or could do at a much lower cost, when I didn't even have a chance to make my case.

    I'm currently an industrial scientist, and have been a government scientist. In both of those positions, I am prevented from fully competing with academic, tenure track researchers for government R&D funding. Why?

Two, I still train and advise students as a non-tenured scientist, I'm just not the guy who puts the hood on them at graduation.

    I compete with academics for patents and private investment. There is nothing stopping an academic from applying for the small business set aside funds, signing a research contract with a government lab, or competing with me for an investor's funds.

  25. not a superconductor, a topological insulator on Single-Atom Layer of Tin May Be a New Wonder Conductor · · Score: 5, Informative

    These guys are talking about a 2D topological insulator. This is the current hot area of research in condensed matter physics, and is absolutely not a superconductor.

    A topological insulator is best described as an insulator, which for very particular types of conduction (direction, location and energy limited) acts like a very good metal. It's really interesting, and scientists are trying to show it will have practical use, and these materials might end up in a computer chip in a few years, but...

    There is a big difference between a lab effect and the real world. Carbon nanotubes have most of the same "non scattering" effects you'd hope to find in a topological insulator. Yet, in most actual devices, they do not conduct in bulk the way theory would suggest. For nanoscale systems (these are nanoscale systems) the environment around the material is nearly as important as the material itself, and scattering from the environment (oxides, metals, air) drastically reduces the performance of the material. There are ways around that, but the additional costs and engineering difficulty are generally enough to prevent any practical commercialization.
