This webpage looks like a tutorial of sorts on fans, blowers, compressors, etc. Offhand, I'd think there'd be a way to calculate pressure differential from power, "disk area" (which is 0.5 m² for your fan), flow rate, etc.

IMO... The news media enjoys a position (and profits) of its own making and at the people's expense. Over the decades, news programs have gone from humdrum, money-losing public service broadcasts to flashy, glitzy extremely high-profit productions. They rely on gut-level sensationalism, and they sensitize and prey on people's fears. Consumer feedback has become very sophisticated, and if, for example, the public strongly reacts to a story of a kitten put in a microwave, the media can immediately search the world for stories of animals put into microwaves and/or other sad stories of kittens, and the people will get a false impression of the world worry that it has suddenly gone crazy over kittens and/or microwaves. We also have 24-hour news channels and more technology to bring the news more graphically to people. And the media will simply claim that they do it because the people want it. I believe that the news media has gone from a fairly balanced view of life to an animalistic knee-jerk reaction nature of reporting. IMO, as in the original Star Trek series episode "Wolf in the Fold", the news media has become a malicious incorporeal entity that feeds on fear.

One of my bosses told me not too long ago that as long as we used "good science" to reach our decisions at work, he would stand 100% behind our work. I can see the same philosophy applied in academia. I think you would need to state the other causes that result in global warming and the mechanisms for how it comes about. You'd probably need to show as much detail/explanation as the teacher/textbooks show. Here's the crux of why the teacher should accept this philosophy. By refuting or attempting to refute man-made global warming, you will prove your knowledge of it. Whether you accept or believe that knowledge seems inconsequential. It's like learning something like the Russian language. You could learn it, speak it, conjugate its verbs, etc perfectly, but you could say that it's a horrible language, that you don't believe in using it and that you'll never use it outside the classroom -- and the teacher has no technical grounds to give you anything but an A+.

I scored 76%. I think I'll stick with the 76.

Heat, or thermal energy, refers to the kinetic energy (½mv²) of molecules, which constantly vibrate. "Hotter" means more velocity, which means more pressure (imagine people in a crowd pushing and shoving each other more), which tends to create expansion, and thus, lower density. Buoyancy causes the heated molecules to rise. This occurs singularly as mushroom clouds caused by detonating nuclear weapons, lighting a match, etc. A constant stream of hotter, lighter gases occurs with candles, home radiators, chimneys, the earth's tropical regions, etc. The less dense air at the top does not fall down exactly because it is less dense (just as a box of cereal has the more dense cereal at the bottom and the less dense air space on top). ...

Uh... well... Treasonous in the sense of betraying one's country.

Regardless of whether anyone thinks Social Security is good or bad, I think we can all agree that what the federal government did/does to Social Security was/is wrong, dishonest and perhaps criminal or even treasonous (seeing as how the people hold the ultimate power in America).

A recent New York Times/CBS poll shows that 18 percent of America supports the Tea Party movement. http://www.nytimes.com/2010/04/18/us/politics/18tea.html Some scientist determined (and I think Richard Feynman mentioned it in one of his books) that a subgroup exceeding a 1/2[math]\pi[/math] proportion (~16%) of a population has a significant influence/sway on that population.

Thank you alien, yes, there is a tiny gray "Run scan in background" button in the lower right corner of the popup that appears after the scan starts. This should do it. PS -- You have no virus scanner?

I have McAfee whose scans (mcods.exe) dominate my CPU (98+%) and essentially lock me out for minutes at a time, so what can I do to tame this beast (Norton won’t load on my machine)? Thanks.

A while back, I discovered recursive patterns in density values using a hexagonal grid, but I didn't think people paid much attention to such things. How do I go about learning if I've found something new? (I had also discovered that the least squared method can be computed {much more naturally} without squaring or minimizing anything, and I chased that around for a few years before finding a university professor who told me I hadn't found anything new.)

Something interesting occurs with this check method when used on square roots of whole numbers. The “product” amounts to the whole number itself, and the product remains constant because any extra decimal places are filled with zeroes. The multipliers are the square root and, thus, are identical. Thus, there are nine possible check numbers (1², 2², 3², … 7², 8², and 9²) resulting in 1, 4, 9, … 49, 64, and 81. These, in turn, simplify into 1, 4, 9, 7, 7, 9, 4, 1, and 9. All together, the check numbers can only equal 1, 4, 7 or 9. Thus, the square root of 2, regardless of the number of decimal places, will never check as “valid” because the check number can never equal 2. The same holds true for 3, 5, 6, 8, 11, 12, 14, 15, 17, 20, 21, 23, 24, 26, 29, etc, but not for 1, 4, 7, 9, 10, 13, 16, 18, 19, 22, 25, 27, 28, etc. Notice that the set of numbers that can never check as valid don’t contain squares of whole numbers, so I’ll call them N numbers (for Never a square). The squares are all contained in the second set, so I’ll call them S numbers (for Sometimes a square). Now it gets interesting! Analyzing the set of whole positive numbers, we find their check values. Some of these values equal 1, 4, 7 or 9, and others do not. Let’s look at the prime numbers. Twin primes (P and P+2 are primes), except for 3 and 5, seem to follow the pattern of an N number followed by an S number. That is, the P prime is an N number, and the P+2 prime is an S number. This holds true for the 35 pairs of twin primes below 1,000 and for the somewhat large twins 3,557 and 3,559. Cousin primes (P and P+4 are primes), except for 3 and 7, seem to follow the opposite pattern of S then N, which holds true for the 41 sets of cousin primes below 1,000. Sexy prime pairs (P and P+6 are primes) seem to follow the pattern of both N or both S, which holds true for the 46 pairs of sexy primes below 500. Sexy prime triplets (P and P+6 and P+12 are primes) seem to follow the pattern of all N or all S, which holds true for the 21 sets of triplets below 1,000. Sexy prime quadruplets (P, P+6, P+12 and P+18 are primes) also seem to follow the same pattern of all N or all S, which holds true for the 7 sets of quadruplets below 1,000. Cuban primes of either form seem to be all S numbers. Eisenstein primes seem to be all N numbers. I could go on, but it's getting late...

Perhaps a certain combination of warm water vapor and carbon dioxide (dry ice) would produce "fogs" that would not sink to the ground or rise into the air. It would be "breathable" in that it wouldn't cause any bodily damage or gag you, and it wouldn't cause damage to most objects except for its warmth and condensation. You would need to ensure enough oxygen is mixed into the fog to stay alive.

I used to be more open and outgoing … and naïve. I wish I could go back. I sympathize with you. For reasons that are still unknown, someone caused me a career setback by spending months deviously obtaining personal information on me, and then sharing it with my other coworkers. At least you were 4 years old when you cried, and it didn't cost you your job. So now I practice anonymity on the web as a necessary evil. ... or I become a hermit. To answer the questions… In real life, do I wear a mask — Yes If I see someone hiding, I think — They have a reason My name and avatar — Are meant to deceive/deflect My avatar represents — Science, also symbolic for me This forum is not a game — Forums are real; but real life is more real

1. Manipulate an equation by treating both sides of it identically. Thus, add 2 to both sides, or divide both sides by v², or take the square root of both sides, etc. 2. When you manipulated it as desired, for example, d = ... , plug values into the right side of the equation to determine the value of the left side. 3. Then substitute the value of the left side for where the left side appears in the original equation along with the other values being used. Verify that the original equation holds true with these values. For example, begin with a² + 2x = n and solve for x. Subtract a² from both sides, giving 2x = n – a². Divide both sides by 2, giving x = (n – a²)/2. Then plug in values into the right side of the equation. So, for n = 19 and a = 3, then x = (19 – 3²)/2 = (19 – 9)/2 = 10/2 = 5. Finally, go back to the original equation, a² + 2x = n, and plug in all the values. 3² +2×5 = 19, giving 9 + 10 = 19 which is 19 = 19. If all the values are not known, these steps may produce something looking like 19p + w³ = 19p + w³, which still proves that both sides of the equation were correctly manipulated (that is, manipulated identically) in Step 1. If plugging values back into the original equation produces two sides of the equation that are not identical, then the an error occurred somewhere in Steps 1, 2 and/or 3.

Because this is looking like a plurality (~40%), which means that more than half of the people didn't vote for it, will this poll be considered the "primary election" with the top two picks facing off against each other? (Too American? )

Doe science tell us that quakes are happening more frequently, or are they just being reported more dramatically? If they're happening more frequently, I'd think that the media would report that too, but I haven't heard anything about it.

I think the easiest way to change the carbon footprint caused by my computer is to dim my screen (ie, lower the Brightness and Contrast) and/or to invert the colors (Press Ctrl+A to see a bluish example of this). Instead of "bright white" pages, our computers could show gray pages with white or black lettering, or black pages with white letters or gray lettering. Black letters on white pages could be optional. Screensavers could simply be black; the power lights will tell me that the computer is on.

The funny thing about self-esteem, shyness and loneliness is that so many people suffer from them, but because of the nature of these feelings, they prevent most people from talking about them, and so, everyone who has them feels like they’re the only ones who are suffering. A man dating someone at his workplace can be very awkward for both people when these relationships end, which most of them will do — except for “the one”. I agree with Phi for All except that it’s better/safer for everyone if the women around a man only network for him. He impresses them, and they introduce him to other women or invite him to join a mixed group or a new crowd. A man can confide in the women around him more naturally, because he’s not trying to date them. Women are often impressed by what other women say, especially friends. A guy shouldn’t ignore married women either, who are generally older and more experienced. They can offer good advice and introduce him to women he normally wouldn’t meet. PS — Porn can get a guy into the habit of looking at women’s bodies and that no one can see him doing it. Revealing fashions combined with careless women can cause problems for men. I recommend that a man not let his gaze drop below a woman’s eyes whether she sees him or not, especially if she’s wearing something revealing. Too many objects, like computer screens and cubicle windows, are reflective. A guy who looks a lot might end up with a bad reputation, a verbal warning about sexual harassment, or a warning letter in his personnel folder. It can be the kiss of death.

I also thought of depression, and I found this: Adolescent Depression - Depression can sometimes occur because life doesn't progress as we plan. - Depression can occur when circumstances unconsciously trigger a very bad memory. However, more specifically focused on your situation, memory loss seems like a key symptom. - May we rule out drug or excessive alcohol use? - Does it occur immediately (such as reading something and then not remembering it when the next paragraph references back to it)? - Does it happen overnight (not remembering during a class what you studied the night before)? - Does it happen a week or more later? - Does it affect your memory of non-academic facts (such as remembering people's names, remembering to meet people for get-togethers,etc)? - Does it affect your memory of non-verbal facts: people's faces, voices, where you put your keys, directions to someone's house, etc? - Does it affect only attempts at current memorizations or does it also affect very old memories from early childhood? At this point, the most important symptom here is that you recognize it's wrong, you don't like it, and you want to fix it. So, although your symptoms make you uncomfortable/unhappy, feel confident that you have this higher level functioning and that you're on the right track.

I might like the Janus logo most of all, and T-shirts etc could show the electrons in mid-orbit. But, yes, it would definitely turn us into zombies. However, I voted for the Supernova because modern logos tend to be über-simple, and there's some sort of glow coming off the letters which somehow looks "galactic" (please enhance this somewhat, see example below), thus the two parts of the logo show the infinitesimal to the astronomical. Oh ... what does the red dot mean? I think the Integral is cute, but if "FORUM" is blue, then the "f" should be too, instead of the "n" (consistency please! ), and the whole thing seems a bit too "busy". Merged post follows: Consecutive posts mergedI don't know what happened, but here's what I was thinking ...

Yes. I think that our exchange is a prime example of this difficulty. It was very easy for you to copy my words (ie, my behavior), but you needed to ask me to explain my thoughts to you. ;)“I know you believe you understand what you think I said, but I am not sure you realize that what you heard is not what I meant.” ;)

The article's language seems very ambiguous to me ... it seems that the software copied actions. It's very hard to copy someone's thought process, but it's very easy to copy someone's behavior.

Like most of life, it's all relative. I think most organisms can compare their distress/comfort with that of others nearby. For example, say someone is a member of a prehistoric tribe. There's a hierarchy, but he end up following a maverick who runs him up and down hills, etc (without any benefit) while the rest of the tribe simply follows along an easy path. While this goes on, he look around and realize he's worn out while the others are in much better condition. When the tribe rests, he arrive sweaty and tired, while everyone else is basically okay, and it astounds him that they start going again as soon as they do. (Sound familiar?) I think all sorts of organisms can figure out that they're going about it the hard way. If an individual copies the rest of the tribe and still cannot keep up, then it becomes a straggler and/or joins a pokier crowd.
