Mechanical vibrations are used to measure molecular relaxations in polymers (rheology and dynamic mechanical analysis). The devices I am most familiar with have an upper limit of about 100 hz, however, by controlling the temperature high frequencies can be effectively measured.
The advice I was given, and I believe the poster as we, was not to read the claims. The claims (should) be the only difficult part to read, as its in lawyer speak.
"The reason Li-Ion batteries are dangerous is the sheer energy density."
A lump of coal has a pretty high energy density too, its not something I would think of as dangerous. The problem with these Li-ion cells have occured b/c of the low onset temperatures of many of the components. The SEI layer decomposes at about 70C. From the models and differnial scanning calriometry data I have seen, this reaction does not release enough energy to cause other runaway reactions to occur. Overheating or a short circuit is need to initiate the other decompostion reactions that occur when the solvent, cathode and anode materials decompose. As I recall the onset temperature of these reactions are about 170C.
"Conservative != Fascist so stop claiming to be conservatives, you aren't."
Not to break into another semantics argument, but I think that the term "conservative" transcends any particular politcal movement. Rather a "conservative" opposes change and prefers tradition.
A conservative would be a fascist if the current regime was fascist, a communists if it were communist. Considering the amount of government spending during the cold war it is completely apt for republicans to call themselves conservatives and want to keep spending.
You are right about the speed of chemical reactions being influenced by temperature. Thats why you can predict the temperature from the rate a cricket is chirping. However, alot of reactions that take place in the human body won't occur readily at body temperature. To get around this problem the body uses enzyemes to provide alternative reaction path ways where the reactions are more favorable.
Interestingly enough I think most of these mega-fauna are in trouble in the areas of africa where they aren't hunted. At least in africa, "tamper free" zones don't work. I can't recall any of the articles I have read, but Death in the Long Grass, by Peter Capstick has a bit on hunting and game management. If you are considering importing these creatures, you might want to read it first.
In africa everything bites.
Don't write coal off just yet. I am sure you have been told since kindergarten that it is "dirty". However, scrubbers, carbon sequestration, and the water-gas shift reaction make it an attractive solution. Plus there is about a 500 yr supply as I recall.
Of course they are dependent on us. Ever see any Amish steel mills? Just b/c they don't use electricity does not mean that they don't need nails, plows, and other commercial goods. Amish carpenters use electric and pneumatic tools. The local Amish tack shop I know is stocked with all sorts of modern items the use medicine for horses, tools, leather treatments, nylon tack, etc. I think from my experience I would have to question the assumptions that they can't deal with we 'English.' They are pretty sharp businessmen.
As I recall from high school (2001 grad) the comma is optional, except for some goverement papers where it is required. This sounds crazy, but the teacher was quite the grammer nazi.
By the way, the text we used stated that: "apples and oranges and peaches and grapes", was also correct.
I don't think he was complaining about christians being "only human" and failing to live up to such standards. I think the point was that many don't even make the effort to try.
How terribly dangerous would thermite be? Aluminum and rust aren't going to do anything by themselves. You just have to worry about whatever you are using to set the thermite off going off prematurely. Even then you are not risking an explosion. Just a fire.
Of course depending on what was compromised a fire might be usful afterall.
As I understand what happened was not that the results were not reproducible, but that the amount of radiation given off had not been correctly calculated. There were also some mistakes relating to electrochemical effects in the system.
In the end there was no good evidense of nuclear fusion, but there was some type of physical-chemistry type reaction occuring. Something related to the desorbption of tritium from the palladium.
What about coal?
From what I have read without breeder reactors we have about 50 yrs worth of uranium left. Coal on the other hand gives us 500.
I know we have all been indoctrinated since grade school that coal is dirty, but scrubbers can be used to get out most of the stuff other than CO2.
Nuclear power is also not the only option for generating hydrogen. Using the water-gas shift reaction you can get H2 from coal.
500 yrs gives use alot more time to come up with something better.
From my experiance the true evangeical is convinced that translaters who translated the king james bible were inspired by god. No need to learn a new language, because the king james bible is more accurate than the original text it was translated from.
Like Heinlein said if you can worship a trinity and convince yourself you are a monotheist any stretch of logic is not too difficult.

No civilians can by grenade launchers in the US, its just a $200 tax stamp.

That's funny I thought they were looking for gold and spices not exploring as an end in itself?

I think you are interested in exergy, not entropy. Back to thermo for you!

If it turns out that global warming is not caused by human activity, but is still happening do we want to stop it them?
