Actually not. The vast majority of casulties caused by a thermonuclear explosion are caused from the intense heat and pressure of the bomb, as they would be with a conventional warhead. Large doses of gamma radiation are of course, released during the explosion, but it only effects people very close to ground zero. And "radioacive fallout" is another big myth about nuclear weapons. The amount of radioactive material left is comparatively small, and on top of that, are alpha emitters anyway are only dangerous if ingested/inhaled and only then if in comparatively large doses.
Actually solids are not a single phase for most substances. Solids can have different states depending on how much pressure is applied. Water, for instance, has numerous phase transiitons in the ice phase. Check out this phase diagram for water.
Some people will still pay for quality. Look at Alienware for instance. And thats where the innovation will happen before the Dells of the world produce the cheap knockoffs.
Well, the flip side of the coin is that you have companies like Google that are doing quite well. They seeem to be a one trick pony(search), but perhaps that trick is very, very good. Ford, GM and IBM are very much old, established companies. Perhaps its time for newer, fresher companies in "new economy" industries(biotech, robotics, nanotech?) to start moving.
, he also confirmed the existence of atoms with the brownian motion paper
This is something I never understood - why did some scientists not accept that matter was arranged in atoms that late? What alternate theory was there?
They're called the police. They patrol the steets at night looking for the bad guys. They are equipped with pistols, fast cars, body armor and even sometimes heavier weaponry and stun gas. Doesn't stop them from getting severely hurt and sometimes killed.
The problem with starting a business is, in the vast majority of cases you need to have very good contacts, and the only way to get those contacts is to either work for a business or have a close friend/relative who will refer clients to you.
That, and no one in their right mind is going to give a contract of any significance to an 18-year old, no matter how smart they are.
No, only brute force algorithms must search the vast majority of the keyspace. Can anyone prove that all possible algorithms have to do this? If, not, then factoring may be easier than we think or want.
It is difficult if not impossible to prove that an algorithm has minimum algorithmic complexity. Your 'proof' must invetiably rely on certain assumptions which you might have good reason to believe but which there is no hard mathmatical basis for being correct. For an example, there is a proof that the general case sorting problem is O(n ln n). The 'proof' however lies on certain assumptions which may or may not be true. There are good reasons to believe that the factoring problem is sufficiently general to not have a polynomial time algorithm, because after centuries of mathematical investigation into the behavior of prime numbers no one has been able to derive any shortcuts to factor a number other than successively testing primes.
There are also always heuristical and approximate methods which may be 'good enough' however. The Miller-Rabin primality test for instance, is a heuristic algoirthm which is only right a certain percentage of the time, but you can run several iterations of it to reduce the error rate below that of your hardware.
Returning to the sorting problem example, in the general case sorting is O(n ln n), but there are several algorithms which run in linear time on certain keyspaces.
The base is superflous. Factoring is approximately linear in the key size as a number, but said to be 'exponential' in the number of digits in the key. The algorithms that exist must search the vast majority of the keyspace. Because we use a binary number system, that is why it is said that adding a single digit increases the running time by 2, because the keyspace has increased by a factor of two. The base has nothing to do with it.
The problem with these techniques is there are no algorithms I know of that account for the effect of light/shadows effectively. So the textures on your objects are going to include shadows. You can notice this effect on one of the images that have linked to in the article.
The reason for this is that if you go to the gym and really work hard the best you are going to do is burn about 400 calories per hour
Exericising gives the additional benefit of increasing BASAL METABALIC RATE (BMR) for a long period after the exercise is done as well the calories you burn during the workout. This is why people who exercise regular tend not to get tired, their metabolism is burning up calories and filling them up with alot of energy.
>Oh, and the best bit about this diet was that it wasn't a stupid fad diet like Atkins, it works well and I was still able to eat pizza, burgers, kebabs, curry and all that other great
stuff and I still lost a load of weight.
Atkins is not a "fad" diet. Low carbohydrate diets have been recommended by nutritionists since the middle of the 19th century, and there is lots of scientific evidence of their superiority over low-fat and caloric restriction diets. Some people are simply ADDICTED to high carbohydrate foods and the solution for most addictions is not moderation, it is abstinence. Do you think our ancestors ate heavy amounts of refined sugar in the form of cookies, ice cream, and candy? No, they ate lots of vegatables, meat, nuts, and some fruits, because that was what was available.
You are probably one of those typees that has a low resistance to weight lost, most likely because you are still young and male. For most people however, caloric restriction while maintaing a high level of carbohydrage intake does not work because it makes them hungry and low on energy.
Because if you can implement a B+ tree, you can certaingly figure out how to deploy Enterprise Java Beans in servlet container of the month, or to write SQL queries that map your business objects to your RDBMS tupes, given the proper documentation.
Not trying to knock anyone here, but if someone is trying to enter a field simply because they think there's money in it, they won't be there very long. Maybe that's what's going on here now.
Oh pulleease. Tell me, if you had $10 million in the bank, would you STILL be doing IT? 95% of workers do their job primarily because of their paycheck.
What ACTUALLY happned was, companies stopped hiring fresh grads because there was plenty of people who already had experience who didn't have jobs who were willing to work for less money. I know programming. I've coded B+ trees and graph search algorithms in languages from C to Scheme to Prolog. You're twidilly little business logic apps are fairly trivial, thank you very much.
Easy, you don't have a mortgage, because you don't have a house, because you can't afford one since don't have a job or have a ridiculously low paying one.
As far as I know, there are no known versions of large segments of the New Testament in Aramaic, nor is there any evidence that such versions even existed. For all we know, they might have originally been written in Greek. This would be especially true of Paul's letters, since he was Roman and his audience was primarily gentiles(non-Jews) then he if he indeed did write the letters that are attributed to him, then he would have most likely written them in a the most suitable tongue, which in the Middle East at that time was koine a dialect of Greek.
What I don't understand is, why don't corporations donate money to scientific endeavors in return for tax breaks? They fund the arts quite often, so why not science?
(and no the war wasn't about oil, or even wmd's. sorry excuse for what will historically be a great policy.)
Then what do you think it was about? Spreading democracy? The U.S. isn't interested in democracy, unless it works to their advantage. See U.S. support for Pakistan(bitter enemy of democratic India and known supporter of terrorism) , Saudi Arabia, Guatemala, El Salvador, and Indonesia. Not to mention historical opposition to "democracy" in any meaningful sense in Vietnam, Chile, and Iran.
Besides, even it was about democracy, do you think that invading a country is the way to accomplish this? Why didn't they just arm opposition groups so they could overthrow the government themselves? Any government, especially a democracy, will inevitably have to be
No, but why should public funds be used for private gain? If American taxpayers are paying for the research, why should they have to pay again to get its benefits ?
I say that someone who deliberately sets out to cause havoc, knowing that their actions will cost jobs, induce fear, require cleanup, new security measures, etc.... that person is terrorizing their audience/victims, and is a terrorist.
So when Congress does something like increase the number of H1B's allowed in the US at the expense of the American work force, would you consider that an act of terrorism?
As to fusion it's really only 30-50 billion$ away from production use. We are just not putting that much money into research. In 2000 there was a plan to create a 1500MW fusion power plant by 2020 but it was scraped to cost's.
A 1500 MW fusion plant that required 1800 MW to run ?
We could easily make a fusion power plant the only real problem is lack of funding. It would take about 5 billion a year for 20 years, which is really a tiny fraction of our GDP, but hey 20 years is way to long for most people to think about.
Fusion was 10 years/$20 billion away 20 years ago.

Well here's someone who has a CS degree who doesn't have a job. And I interned for two different companies (DOD racketeers, er, contractors)
I did internships, I did out of class work. Its been 4 years since I've graduated with my BS in CS, and still NO JOB.
Oh pulleease. Tell me, if you had $10 million in the bank, would you STILL be doing IT? 95% of workers do their job primarily because of their paycheck.
