Seife suggests the FDA is trapped in a co-dependent relationship with the pharmaceutical industry, and needs strong legislative support to end its bad behavior.

He wants the completely-non-influenced-by-big-money legislature to do something about the FDA being co-dependent with big-pharma...

Yeah, that sounds like it's gonna work...

You know they changed it right because Pizza Hut paid them a pile of cash? Anyone who goes along with the change to Pizza Hut from Taco Bell is an asshole. It doesn't even make sense because some scenes still show the Taco Bell logo.

Your theory doesn't take in to consideration Pizza Hut and Taco Bell are part of the same company (was PepsiCo at the time of filming now Yum! Brands) and Pizza Hut and Taco Bell even have co-located in some stores (although there are other combinations like KFC/PizzaHut and KFC/TacoBell).

The commonly accepted rationale is that Taco Bell is mainly just a US brand and since PepsiCCo paid for the product placement originally, they wanted to substitute one of their well known international brands for the international release of the movie to get more advertising mileage out of the placement...

But PepsiCo probably had to pay for the change, and of course they did a crappy job of executing the change...

nah - even modern dimmers are digital too.

I'm not so sure you can classify a chopper circuit driven by a potentiometer a digital circuit (although they do have digital dimmers now days, most so-called "modern" dimmers are not)...

It's these chopper circuits make your light bulbs hum...

Similarly, the switched mode power supply in your computer is much more analog than a digital circuit...

Let me be the first to predict Hexagonal Graphene.

Actually typical graphene is already a hexagonal lattice...

However, you might put your money on a square lattice (aka quadrille) or perhaps triangular lattice or the others listed here...

But instead of a boring quadrile or pentagonal tiling, let me be the first to predict a Penrose tiling... Now that would be cool ;^)

Comment Re:I'm not autistic (Score 1) 289

It's especially obnoxious since it's being diagnosed lately with sociology, rather than actual science.

AFAIK Autism is technically a syndrome (a set of symptoms or in this case behaviors), which is effectively defined in sociologic terms (psychs likes to call certain behaviors that are not "normal" a disorder). When science finally figure out what causes these symptoms/behaviors, then it will be either a disease (or maybe not). Just like GRID/AIDS was a syndrome and then they figured out HIV infection was a diagnosable factor that seemed to explain AIDS. They haven't gotten that far with Autism yet, but that doesn't mean it's not real or that they won't eventually figure something out. But maybe not.

you can't put nuclear close to a fault line, in a place where there's tornadoes or hurricanes, and you generally need to put it next to a river for cooling though you can also use giant cooling towers. And of course, you can't put it anywhere near a metro area.

Apparently you can...

They built San Onefre right near a fault line...
They built Wolf Creek right in tornado alley (ironically this was NOT one of the multiple plants that have been actually hit by tornados)...
12 east coast nuclear reactors were in the path of Hurricane Sandy...
They built Indian Point near New York City...
They built Palo Verde not near any natural body of water (they use treated sewage water from nearby Phoenix suburbs for cooling)
etc, etc, etc...

I'm not saying any of this was/is a good idea, but just that the mere existence of real nuclear power plant in these locations has trumped your statement.

Nuclear reactors don't need water. You can build liquid metal cooled reactors. Metallic sodium is one such metal used.

Although some reactors have been built with liquid metal cooling, nearly all have been experimental reactors only. However, even in liquid metal cooled reactors, generally the turbine that actually generates the electricity is driven using a steam cycle (which uses water). So technically a nuclear reactor doesn't need water, but generally you want electricity out such a reactor (unless you are using it simply to generate transuranic elements)...

Correct me if I'm wrong, but does this mean that the neutrons literally flow across a fourth dimensional axis, and then somehow bounce back after they've moved some distance on one of the other axes, landing in the trap while within our plane of the fourth dimension?

Not exactly, the quirk they are testing is effectively the neutron travelling through both "branes" in a superposition state (well, it's actually a bit more subtle than that, but that's the easiest way to explain it).

If so, how are they supposed to spot the neutrons the moment they cross into our brane but before they move into another one?

They aren't tracking specific neutrons, they are making a statistical assumption about a collection of neutrons.

More specifically, by running the experiment multiple times with the neutron source a different distance away from their shielded measurement chamber and at different times of year (to account for different magnetic vector contribution from the sun), they can potentially statistically isolate neutrons detection events that are expected to spontaneously appear (e.g., as a result of cosmic rays originating outside of experimental parameters) from those neutrons that supposedly move in and out of our "brane" as a result of superposition which are sourced locally (whose flux depends on the distance from the source).

We'll see how it goes. They haven't done the experiment yet...

If your going to shoot the railgun the same way you shoot conventional guns what's the point?

The main point of a railgun is that you don't have to launch the payload with gunpowder, but with electricity. There are more safe and battle-field redundant means for electrical generation than the existing storage and transit requirements for gun-powder.

Even if they had the same mussel velocity.

There are a lot of people who behave like they are still in high-school...

Since evidence suggests that "cliques" and "bullying" continues through university and into business** being exposed to it and learning to deal with it is likely an important life skill to be learned (similar to EQ, and perhaps arguably more important than academics). I'm not saying home schoolers (of which I know a few) can't learn these skills, but depending on your career aspirations, growing up in "tougher" environments can often be a formative learning experience for young folks.

They are more professional, less crass and boorish.

You say that like it's good to be professional all the time and bad to ever be crass and boorish. I guess to each his own, but personally, I would find a such a permanent professional veneer existence rather sterile and boring (even in the office)...

They don't attract notice except in passing to note someone seems strangely confident in themselves.

FWIW, confidence is a two edged sword. The risk with confidence, is over-confidence, and not knowing yourself. This in itself can benign in the form a comparative-optimism which can contribute to delusion that they are more likely (than average) to have good things happen to them and less likely (than average) to have bad things happen to them which often leads to a happier life. Or in the other extreme a Dunning-Kruger handicap throughout life. More confidence is not always better, but more self awareness generally doesn't hurt (too much, although can be depressing at times).

Sometimes it's hard to find out who you are and develop self-awareness when constantly in an environment created by your parents. I've seen that happen many times in my university (with both home schooled and highly sheltered children), since they weren't exposed to a more free-wheeling environment before, they we just discovering who they were when the consequences were much higher (if you want an analogy, not unlike getting the chicken pox early in life vs when you are an adult, or learning to drive for the first time on your playstation vs with a 1/2 ton steel box with seatbelts and airbags).

There is also some evidence that artificial confidence can be crippling for some children (e.g., forced to show artificial confidence, but knowing they are untested, some children are extra fragile when confronted with failure and develop coping strategies than can be self-defeating or even anti-social).

**They range from the more benign "lunch-invite-crowd", cafeteria table, smoke-break crew, to the more malignant country club good-old-boy variety and everything in between. Some folks just call this office politics to make it somehow sound more mature, but it's really just the same thing...

Math education at most colleges don't have a single class in common with math majors.

Ouch, that's depressing.

One of my good friends is a junior high math teacher, and although this is somewhat true, it is a bit misleading.

One thing that I have found is that for a subject say like algebra or elementary set theory, there is a level of understanding you need to pass a class and another level of understanding to teach it to someone else that has a lower level of understanding than you do. Taking linear algebra and group theory classes letting algebra rust isn't then same as learning basic algebra and geometry more in depth augmented with a survey of linear algebra, statistics and leaving the group theory on the table.

As a personal anecdote, when I was in high school, I was pretty advanced in math so my math teach made me "help" teach math to some of the other students in the class. At the time, I somewhat resented this imposition, but when I got to university (and did some tutoring and TA work), I found that these exercises helped me learn this basic material much better than I would have just to get an 'A+' in the class (and forced me to develop more than one strategy to get people to understand these topics).

Of course on the orange hand, Kyocera has low volume phones and their ceramics group makes their own sapphire, where Apple currently needs to contract to get access to sapphire manufacturing.

I suspect that won't change in the near future, but perhaps, eventually, Apple will attempt to get their sapphire coated glass idea manufactured at some point. I'm guessing that although they would undoubtedly like exclusivity, I don't think that will be in the cards following that whole GTAT fiasco, so they might have to suck it up and invest in their own production if they insist on that...

Astronomers Find Vast Ring System Eclipsing a Distant Star 85

Zothecula writes: Astronomers from the Leiden Observatory, Netherlands, and the University of Rochester, New York, have discovered a massive ring system obscuring the light of the young star J1407b. It is believed that the rings belong to a massive planet or possibly a brown dwarf, with an orbital period of roughly 10 years. The giant planet boasts a ring system around 200 times larger than that of Saturn, the only planet in our solar system hosting a ring system of its own."
