It would only mean that our prior measurements of the value of c were slightly off, and we now have a better measurement.
Nope. The value of c is defined precisely as 299,792,458 m/s. The precision of light time-of-flight calculations as done by OPERA are limited by the precision of the clocks; the best atomic clocks are precise to better than 1 part in 10^15. The 60 ns difference reported by OPERA is an O(10^-6) effect and can be measured even by cheap clocks.
The difficulty in this measurement is that the clocks at CERN and the detector at Gran Sasso, a distance of over 732km, have to be synchronized at the ~10ns level. This cannot be done reliably with GPS clocks and generally is extremely difficult; it is the most likely source of error.
The damned requirement for it to be in the gasoline. IT ruins gas mileage and the gas stations are NOT selling it for 5%-10% cheaper because that is what your gas mileage loss is from running E10. They sell that crap at full price because consumers are too stupid to know better. (Most people think that "premium" is a better gas! The lack of education in fuel that is used daily by the population is incredible)
I have a flex fuel car, it get's 25% less gas mileage when running on E85 but it's designed to run on the stuff. And all the stations around here selling it are price gouging it so hard that it's only 20% below the price of the E10.
This makes E85 a net loss for me to even use it. I can be with the enviro-freaks and waste 5% gas mileage by running E85 or I can run the E10 and get optimum gas mileage at the quality of fuel available and get the most Dollars per mile out of my expense. When E85 first came out it was 40% to 50% cheaper than gasoline so I was running it all the time in the flex fuel van. But in Michigan it's $3.29 a gallon while Indiana it's $2.59 a gallon (as seen this past weekend on a trip to Chicago) There is no $1.00 a gallon tax on it, IT's that Michigan only retailer of E85 is Meijer and they are price gouging it.
I'm done with Ethanol. Until they start using real sources like switchgrass that produce more of it per acre and actually try to make it a viable fuel that is not based on corn subsudies... it needs to go away...
EXCEPT: IT's a fantastic racing fuel. I have 10 friends that are in racing and all of them have modified their cars to use ethanol instead of racing gas. IT's cheaper and they are getting MORE power from it One friend has went from 12.2 on the quarter mile to 11.9 just by changing fuel. Plus they can afford to race at $3.29 a gallon instead of $6.89 a gallon.
Ethanol has a lower energy density than gasoline, but a much higher octane rating. The high octane rating allows much higher engine compression ratios resulting in better thermodynamic efficiency. This is why your racing friends see a benefit; their engines are designed for high octane fuel. Flex fuel engines are designed
to tolerate the 87 octane rating fuel at the pump and have normal compression ratios. This is the problem with flex fuel; E85 results in worse performance because
the engines can't take advantage of the high octane rating.
This possibility was strongly considered in the 1990s. Such sub-luminal objects were termed MACHOS, as opposed to the other leading theory, where dark matter is composed of WIMP particles which rarely interact with ordinary matter (except gravitationally). The MACHO theories
are now strongly disfavored by observations of the cosmic microwave background. The universe didn't produce enough baryons (the particles which give stars, planets, and all ordinary matter most of its mass) to account for all of the dark matter.
This is incorrect.
Blue photons are not more useful for photosynthesis than red. The extra energy is just thermally dissipated in the plant. Plants have no real need to use extra energy anyway, since the rate limiting step of photosynthesis is carbon fixation. This is the fundamental reason why plants do not use green wavelengths.
This is not to say that blue photons are not useful to the plant; they control the phototropic response (e.g. bending toward light).
As an engineer, this is the part I'm most interested in in this subject area: getting from some theorized effect in physics to being able to create and control this effect at will, and then coming up with useful applications for it. Maybe I'm missing something, but it seems like schools gloss over all this stuff; they talk about Einstein coming up with E=mc^2, briefly mention some guys working on the Manhattan Project, and boom, next thing you know there's atomic bombs exploding.
You should start by reading about this guy named Fermi.
Somehow, I'm not so impressed, considering Moore's Law predicts a roughly 1 million-fold (= 2^(30/2)) increase in transistor count over the span of 30 years...
Once I've converted folks, I've often put a sheet of paper next to the computer, listing equivalent options between Ubuntu and Windows. If you want to do something and can't figure out how immediately, look at the list. Eventually, that list will disappear from use. I always leave my cell phone number and a card listing the hours where I'm not otherwise occupied.
Can you post that list here? Sounds useful. Thanks.
My prescription is 7.5mg hydrocodone, 500mg acetaminophen (standard - though there are a few variations on the amount of hydrocodone). The FDA has enforced that amount of acetaminophen, for two reasons. Hydrocodone is relatively addictive, and acetaminophen often induces a huge amount of nausea.
Generally, it is the narcotic causing the nausea, not the acetaminophen.
The FDA made the drug companies put acetaminophen into the narcotic painkillers to keep people from recreationally overdosing on them (same as they "denature" ethyl alcohol that you can buy at the hardware store by poisoning it with methyl alcohol)...
This is not true at all. Acetaminophen and narcotics are mixed because the combination is a much more effective pain reliever than either alone.
The human genome contains ~3 billion base pairs. E. coli, for instance, has only 4.6 million, a factor of ~1000 less. I will safely say that E. coli is a "simple" life form relative to humans.
Parent is 100% on the mark. Nearly everything involving chemistry is governed by quantum mechanics, including the molecular bonds and photon absorption which are core to photosynthesis.
But these are predictions based on the standard model, which describes particle physics quite well. What the grandparent should have said is "since these predictions are based on the standard model, there is a high Bayesian degree of belief that they will hold."
The alcohol/CO2 ratio produced by yeast also depends on anaerobic vs. aerobic respiration, with the latter producing no alcohol and much more CO2. There is a fair amount of dissolved oxygen in bread dough, and the yeast is killed quickly by baking, so there is significant aerobic respiration.
In making beer/wine, there is significant aerobic respiration at the beginning of fermentation, but eventually the oxygen is gone and anaerobic alcohol production begins.
I am an excellent programmer, but working 9-5 in a cubicle writing code scares me and does not seem like a good way to spend the next 30+ years of my life.
Have you considered science, as others here have mentioned? Atmospheric science, in particular, is computationally intensive and can often be started in grad school without any undergrad exposure. With a CS degree and programming experience, you could very quickly get involved in atmospheric science research.
No. It isn't true. Instinct is indeed to chase pretty much anything that moves, that isn't a 'friend'. ...

I've never seen a theoretical description of any transistor device that required any form of quantum mechanics for its explanation.
So you learned about transistors without discussing bands?
