There is a whole swath of biological research under the banner of "basic science"...

Absolutely. I've worked both with pure biologists and physicians (and biologists in a medical context) and they have dramatically different outlooks and mindsets. Many, many biologists are deeply interested in understanding what is going on, while physicians and medical-focused biologists are much more interested in finding stuff that works to solve this problem.

The divide is very similar to that between pure and applied physicists, although for some reason we don't talk about "applied biologists" (perhaps we should.) Pure physicists are simply trying to find answers to questions; applied physicists are trying to find solutions to problems. The same is true in biology.

In places where people have to worry about starvation I wonder if IQ might even be a liability.

Brain size and IQ are not particularly correlated, and I've seen at least some research suggesting that people with high IQs or more education are actually more efficient at using their brains, to the extent that there is some thinning of the grey matter in such individuals in their late teens or early 20's.

Thinking does take more energy than not, but this isn't a big effect compared to brain size: http://www.scientificamerican....

I suggest you ask evolutionary biologists.

And evolutionary biologists will ask, "What is the evolutionary advantage of intelligence?"

What we think of as "intelligence"--the specifically human abilities to build complex machines and to use anything to represent anything else and to create unbounded chains of logical inference--is almost certainly an epiphenomenon of having a brain big enough to engage in the kind of complex social and cultural behaviour that developed due to sexual selection in our evolutionary history.

The human brain is like the peacock's tail: men with big brains were more likely to get laid, probably because we could be more entertaining and interesting to women with big brains. Once the process started it ran away with itself, until both men and women ended up with these enormous brains that happen to be able to think deep thoughts.

Evolution does this kind of thing, like flight-feathers evolving from modified scales that were selected for thermal rather than aerodynamic properties.

Why is there a whole raft of genetic diseases in the human population now? Shouldn't they have been "selected out" a long time ago?

Many genetic diseases are the result of optimizations for other things (anemia is related to malaria resistance, there is some problematic gene in a Jewish sub-population that is related to plague resistance, etc.)

Evolution is continuously running an extremely complex multi-dimensional optimization problem with a time-varying objective function. Local minima abound, and it's easy for organisms to get trapped in them.

Furthermore, kin selection and possibly group selection play a role in human evolution, which makes the whole thing even more complex and non-linear. So looking at specific genes and saying, "That doesn't make sense!" as if there was some obligation for the universe to "make sense" to our naive pre-scientific intuition is fairly silly.

The human genome is a Rube Goldberg apparatus that manages to make hundreds of thousands of products out of 40,000 strongly interacting templates plus a bunch of ridiculously inefficient secondary control mechanisms like micro-RNAs (which in some typically degrade already-transcribed mRNA). Pointing to one step as if it can be considered in isolation from everything else is not a good move.

Loss of vitamin C manufacture could well have to do with the development of some other pathway that was more important at the time, and may well continue to be more important today. The only way to really find out is to either a) understand the genetic trade-offs in detail or b) ask some volunteer to have their vitamin C production turned back on by a technique like this. Personally, I'd recommend the former.

Given how weird humans are developmentally, some things like this may be important when we're young and not so much when we're older, so in the fullness of time we may find we can turn on vitamin C production only after people mature, for example. The possible range of futures, given how little we know now, is large.

In the meantime, we have plenty of people with genetic diseases that we know the cure will not significantly disrupt their cellular machinery, because we have lots of examples of people without those diseases who are just fine.

Photons in the visible light range are not sufficiently energetic to create an electron-positron pair. I do not know if the photons in question were in the visible light range or not.

The photons were in the visible, but the e+/e- pair exists "off the mass shell", which is an obscure way of saying that the normal conservation laws don't apply. There is an uncertainty relation that goes dE*dt >~ h/2Pi, which is to say: you can violate the law of conservation of energy by any amount so long as you do it for a short enough time. That's what's happening here.

That said, this whole thing is pure speculation, and somewhat problematic speculation at that. If you take the first neutrino detection seriously, the real question becomes not the difference between the first neutrinos and the light, but why the one neutrino detector has such a different arrival time. Conventional wisdom is that it is an instrumental artifact, and that's a pretty good bet.

If it is not--and this slowing-down-light is real--then we need even more new physics to explain why the Mont Blanc neutrino detector saw such different arrival time from three other detectors: Kamiokande II, Baskan and IMB, all of which detected events that are consistent in time of arrival.

Their energy sensitivities are not that different, and there's no very obvious explanation of why some neutrinos would happen to make it out earlier than others, particularly when segregated by detection technology.

"In this landmark book, Scott Page redefines the way we understand ourselves in relation to one another. The Difference is about how we think in groups--and how our collective wisdom exceeds the sum of its parts. Why can teams of people find better solutions than brilliant individuals working alone? And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique? The answers lie in diversity--not what we look like outside, but what we look like within, our distinct tools and abilities.
    The Difference reveals that progress and innovation may depend less on lone thinkers with enormous IQs than on diverse people working together and capitalizing on their individuality. Page shows how groups that display a range of perspectives outperform groups of like-minded experts. Diversity yields superior outcomes, and Page proves it using his own cutting-edge research. Moving beyond the politics that cloud standard debates about diversity, he explains why difference beats out homogeneity, whether you're talking about citizens in a democracy or scientists in the laboratory. He examines practical ways to apply diversity's logic to a host of problems, and along the way offers fascinating and surprising examples, from the redesign of the Chicago "El" to the truth about where we store our ketchup.
    Page changes the way we understand diversity--how to harness its untapped potential, how to understand and avoid its traps, and how we can leverage our differences for the benefit of all."

The memo cites case law to justify the suppression of 4th and 5th amendment rights. For example:

at least where high-level government officials have determined that a capture operation overseas is infeasible and that the targeted person is part of a dangerous enemy force and is engaged in activities that pose a continued and imminent threat to U.S. persons or interests the use of lethal force would not violate the Fourth Amendment. and thus that the intrusion on any Fourth Amendment interests would be outweighed by "the importance of the governmental interests [that] justify the intrusion," Garner, 4 71 U.S. at 8, based on the facts that have been represented to us.

and:

In Hamdi, a plurality of the Supreme Court used the Mathews v. Eldridge balancing test to analyze the Fifth Amendment due process rights of a U.S. citizen captured on the battlefield in Afghanistan and detained in the United States who wished to challenge the government's assertion that he was a part of enemy forces, explaining rbat "the process due in any given instance is determined by weighing 'the private interest that will be affected by the official action' against the Government's asserted interest, 'including the function involved' and the burdens the Government would face in providing greater process." 542 U.S. at 529 (plurality opinion) (quoting Mathews v. Eldridge, 424 U.S. 319, 335 (1976)).

So if I'm reading this correctly, 4th amendment rights don't apply if the government deems that its interests outweigh yours, and 5th amendment rights don't apply if the the government deems that its interests outweigh yours or the government asserts that it would be excessively burdensome to give you due process.

The only reasonable interpretation of this is that the government of the United States has become exactly what the Framers feared: an utterly autocratic organization that asserts its own interests over and above the interests of citizens who may come into conflict with it.

Comment Re:More than one Higgs Boson? (Score 3, Informative) 42

So, how can there be more than one Higgs boson?

Physicists have a funny way of talking about theoretical entities, particularly these days when theory almost always leads experiment. We have years or decades to talk about theoretical entities, and that leads to a strange nomenclature.

"The Higgs" is actually a class of particles. In the "bare" electro-weak theory none of the particles have masses. The only way to give them mass is to break one of the internal symmetries of the theory, and one "natural" way of doing that was invented by Peter Higgs and others in the form of a massive scalar field that takes on a non-zero vacuum expectation value as energy decreases (this is the famous "Mexican hat" potential.)

Suppose we arrived on Earth from Mars and were observing the inhabitants, and we wondered how emergency vehicles would get through busy traffic. One of our number--call it Sggih--theorizes that humans, being visually-oriented, might use a flashing light to warn motorists of an emergency vehicle. Others might elaborate on this and suggest that both a flashing light and a loud noise would be use. All of these types of local warning mechanisms might go under the name of Sggih, with the original one being the "minimal Sggih mechanism" and the other ones going under different names.

In the meantime, there are those who think that humans are telepathic, or use radios, or some other non-local signalling mechanism.

Then one day in the course of observation a Martian--and let's say Martians are deaf, the air being so thin there--sees an emergency vehicle with a flashing light on top zipping through traffic. Horray! The Sggih mechanism is correct! At least probably... it may be that wasn't an emergency vehicle but some kind of advertising stunt. And if it is the Sggih, which one is it? Further research is required to determine if humans use the minimal Sggih mechanism or one of the more complex elaborations...

This work is in the vein of that further research, and the outcome strongly suggests that of the various theoretical possibilities, nature is actually using the minimal Higgs and that is what has been seen, rather than some unexpected but similar exotic particle.

All of this is good news for those of us who are unenthused by supersymmetry and other more-or-less exotic extensions to the Standard Model.

Mathematics is a language. As such, it is created.

The interesting thing about math is that it is a language that reveals underlying isomorophisms, like the one described in TFA. This feature is one of the things that leads to naive people thinking that the math somehow "precedes" the things it describes.

But we see similar isomorphisms in all languages. Consider the "ballad" form of poem. It occurs in incredibly diverse contexts, but the underlying structure is always the same, which means you can sing "Amazing Grace" to the tune of the theme from "Gilligan's Island". So claiming that "pi" shows up in a variety of contexts doesn't prove anything except that it reflects those parts of the universe we find it interesting as humans to describe.

Furthermore, mathematical descriptions include extraneous bits. Wave equations have both advanced and retarded solutions, for example. If the math truly "preceded" the reality you'd expect that this would never happen, or that there would be some mathematical (rather than empirical) principle that let us get rid of the parts that don't describe reality.

The role of mathematics in biology is an, err, evolving one. The possibility of a law-like mathematical description underlying biological and evolutionary processes is at least worth speculating about: http://www.amazon.com/Darwins-...

you think we should ban a classroom discussion of the 2nd Law?

I think it should be MANDATORY to teach the 2nd law of thermodynamics in any physics education. I wish your teachers had been more clear on it. Your notion of the 2nd law is clearly flawed or incomplete, as it would prohibit the natural formation of highly ordered snowflakes from chaotic water vapor, as well as prohibiting countless other common physical processes.

The 2nd law of thermodynamics says that the total entropy of a closed system tends to increase, with overwhelming probability. It does not apply to any system subject to a flow of energy an outside source. It not prohibit one location or object in a system from increasing in order while other objects/locations in that system have an equal or larger increase in disorder.

The earth is receiving energy from the sun. The enormous entropy increase within the sun easily "pays for" the ongoing creation of order and complexity here on earth. So long as the sun shines, that energy flow can and does fuel natural self-organizing physical processes. You can see this in snowflake formation, the self-organization of hurricanes, the development of an individual organism, as well as the genetic evolution of a population. There is no violation of the 2nd law here. The sun's energy input pays for, fuels, these self-organizing natural processes.

What branch of Science did you say you were from?

Computer science, with an active interest in physics and science in general. Computer science deals extensively with Information Theory, the ways that information can measured, processed, transformed, and CREATED. Evolution is not merely a "theory", it is an applied science. Evolutionary Algorithms is a field of computer science where complex, ordered, useful, problem-solving information is CREATED by replication with mutation and natural selection of "digital-DNA". I have personally witnessed the fact that evolution can and does create complex useful new information. It is an applied science put to active use in one way or another by a majority Fortune 500 companies. It is quite common for evolution to create designs better than the best "Intelligent Designs" by human engineers. One particular case comes to mind of one team that applied evolution to jet engine design, which evolved an engine more fuel efficient than any human engineer had ever been able to achieve. And there is at least one company solely dedicated to filing patents on valuable innovations generated via evolution.

Here is a grossly oversimplified illustration. Roll one hundred dice. The chances of them all coming up 6 is effectively zero. Now apply evolution. Take that random result and REPLICATE it, and lets apply one MUTATION re-rolling one random die. Now SELECT (keep) the set with the higher total, and kill (discard) the set with the lower or equal total. After approximately 3000 replication-selection steps you will have a perfect set of all 6's.

This process works even when you do not have a pre-determined target. All it requires to work is that you have some means of measuring which set of DNA is "better" or "worse" than another. Evolution will generate whatever information is required to satisfy the selection criteria.

But as I said, that was a grossly oversimplified example. Evolution's power to generate information is exponentially increased when there is a population with sexual reproduction (genetic recombination). This has been mathematically proven by the Schemata Theorem (J. Holland 1975). I won't attempt to explain it here, but a Google search on schemata theorem turns up 122,000 results. It is a seminal paper, widely cited by subsequent scientific work in mathematics and computer science and biological evolution. It mathematically proves a major principal whereby population evolution is almost infinitely more powerful than the trivial dice example I gave above.

Now the 2nd law of thermodynamics says: "All natural systems (e.g. nature) progresses from a state of order (creations) to a state of chaos (puddle of mud)".

Yep, it's conceivable that Loki exists and created the universe 6 hours ago and all of your memories and all of the apparent age of the earth is a deliberate fraud. It's conceivable that you're a disembodied brain in a jar wired to to some Matrix-style fictional reality. And it's utterly absurd to waste time with such things.

You will believe 2+2=3, if a malevolent god wants you to believe it.

If the earth appears to be 4.5 billion years old, then either the earth actually is 4.5 billion years old or Loki crafted a deliberate deception of a 4.5 billion year age. Either acknowledge that you worship Loki, or drop this nonsense a planet-worth of evidence of age might be some elaborate deception.

You cannon profess to believe in a benevolent god while rejecting truths plainly and exhaustively revealed by the scientific study of the world. If the world appears old, then the world is old. If evolution appears true, then evolution is true. If god exists, and evolution is true, then god simply created a universe which included evolution as part of the design.
