The point to my post was not to nitpick at technicalities. The original poster asked a question about relative energies, and I didn't think that the reply really answered it. Therefore, I elaborated. I only spent 3 words out of 125 (2.4%) in my post on the create/release issue.
It may not have been a groundbreaking essay, but at least I didn't resort to personal attacks.
Would the system be able to generate enough energy to control itself, and have excess power to give away?
The easy answer is "Yes". Fusion reactions create an amazing amount of energy
The real answer is "No, not so far"
The origional poster was correct, a huge amount of energy is used to initiate/control this reaction. Fusion reactions do release (not create) an amazing amount of energy, but so far we have had to use an even more amazing amount of energy to control it. We are getting closer and closer to breaking through the efficiency barrier, and I don't doubt that we will someday. It's just going to damn slow.
Well, we have been able to get a massive payback in terms of energy release. It's called a hydrogen bomb. A conventional fission bomb is detonated right up against a bunch of hydrogen isotopes, quickly achiving the tempuature and pressure necessary in order to fuse.
Seriously, I do enjoy reading/flipping through a real book much more than a text file. The feel of paper and flipping through, being able to stick your finger on a page and go on so that you can jump back, it all makes it much better. Not to mention that there is way less eye-strain. I've had friends send me files of books (Hobbit, LotR, Sillmarilion among others), after trying to read them for ~3 min, I went out to a bookstore and bought the damn books. $52 well spent.
The only advantage I can see to e-books is searchability. I do waste time trying to find info in paper books that I could easily find in seconds with an electronic copy. If I had one, I'd probably find the page on the e-book, and then open up the paper book to that page.
I just (like 10 min ago) did a study over about 4 blocks of sidewalk. It was along a large road going through a very large campus (UIUC). I counted ~1100 black spots ~2-3cm in diameter, just like the ones in the report. There were virtualy none under overhangs, but the highest concentrations were just outside overhangs, and near trash cans. Trees seemed to have no effect, whether the spots were under, near, or far away from them seemed to have no effect on concentration. Far away from buildings, there were fewer spots, but high concentrations still existed ~10m away. The few parts of brick sidewalk (around covered bus stops) had almost no spots. There was not nearly as much in streets, but there was in crosswalks
The fact that they are concentrated around trash cans and near buildings, not under overhangs but under trees, and were in crosswalks but not streets all lead me to guess that they are placed there by induviduals, so probably chewing gum built up with crud. As for why they were not under overhangs, maybe there is a sub-concious predispositon not to spid out gum indoors, and the overhang might trick their sub-concious into thinking that they are still inside.
Roofing tar would all be concentrated right up against the buildings.
I suspect that this is the same phenomena as in NJ
I find it supicious that these people claim that the blobs start out 6" accross, and then shrink way down to dry 1" spots, yet there are only pictures of the spots.
Ok, so there is some background spotting on many sidewalks, which MAY explain the smaller ones. The yet unphotographed larger ones could be from public exaguration/hysteria. here are several examples of such events. In particular look at the seattle winshield pitting in 1954, and the school gas leaks in 88. I'd bet that those spots are usualy there, just that nobody paid attention until now.
Wait, so was the cause ever found? Or was it just normal pitting that many people have in their windshields from gravel, etc. My last car had one...
That would be funny if some guy in that other town suddenly had a pit in his windshield that he couldn't explain, and ran around in circles blaming it on fallout, and then the rest of the people of the town noticed pits that they haddn't seen before and fed the hysteria, and then as it passed by word of mouth more people in seattle started noticing, and by that time it seems as if there is an epidemic of winshield pitting, when actualy it is just normal.
No, but I have heard of some VERY interesting studies on the crater patterns on Venus. On all planets, some of the land is newer then other land, so there are more craters on the old land than the new. However, on Venus craters are perfectly evenly distributed all around the planet. This could point to there not being any new land formation, but there aren't enough craters to account for that (even after factoring in the thick atmosphere burning up meteors).
The answer: Many geologists belive that there was a cataclysmic event on Venus the completely regenerated all of the land at roughly the same time, a couple of hundred million years ago. Maybe a huge asteroid impact, or maybe a natural vulcanic phenomenon.
I'm to lazy to do a google search for you, but it's neat, huh?
Back to #2, I was looking through many of your comments for the past several months, and I noticed this one:
Hey, does anyone know why I have a score of 0 and my karmas at -3? I post some pretty darn good comments!!! Any suggestions?
When you Karma is negative, you automatically get modded down to 0. And I'm sorry, but no, you don't post good comments. I'm not trying to insult you here, but they often seem naive and whimsical. When you try to be funny, you're not. Case in point: this You seemed to be talking out of your ass. Gravity is probably NOT quite like EM. Also, the Weak force is many many many times more powerful than gravity. Look at this chart. It some cases, it is almost as strong as EM.
A tip for good karma: People like it when you have links to support your point. Learn HTML and put links in your comments whenever possible. Google is great for finding relevant information.
You're right, but I think you misinterpreted what he was trying to say. He meant that if Silverpit came out to be at 65 million years, then maybe it hit within a few hours of Chicxulub. Of course, with all of this geologic dating, you're right, there is a large margin of error and we'll probably never know.
After all, a lot of meteorites hit the earth every million years.
Not this big they don't! A 12 mile crater! But I guess that it could be a statistical anomaly.
Theorists who are not involved in the research, but whose computational results must be used to interpret it, have recently uncovered errors and uncertainties in their own work. For that reason, the Brookhaven experimenters say they are not ready to claim they have proved a new form of matter exists.
They aren't claiming anything yet. They have something that MIGHT point to this new matter. And they're not just pulling this out of their asses either. Supersymetry theory claims that each matter particle has a corresponding "supersymetric" particle, a kind of a shadow particle. squarks, sleptons and the like are expected by this theory. Of course, this is just one of a few theories trying to supplement or overthrow the standard model, and has not nearly been proven.
Don't make snide comments at people who are releasing experimental data without a conclusion. Right now, all they're saying is that they are measuring a.6 wobbles/sec difference from what they expected, that's it. They aren't claiming anything else yet. Eventually they will either make such a claim when they have enough solid data, or they will drop it due to lack of information or because they believe it is false.
I like them for digital cameras. Sure you could use any of the other media to store a lot more pics, but floppies are cheap and don't require any hardware that most people don't already have (card readers).
I am determined to never let floppies die. I even put an old 5 1/4" drive in my computer. Live on!
I saw this figure mentioned in the boeing article as well. I don't understand where it comes from.
If an object sitting on the ground were to no longer feel the earth's gravitational pull, I don't think that it will fly up into the air. At first, it would just hover up against the ground. It would continue moving at ~1050mph (the tangential velocity of an object on the earth's surface) in the direction it was moving when the gravity stoped. It's like if you were to stand on the edge of a fast moving merry-go-round, and slip off. In the first few instants, you would have almost no speed relative to the ride, but you would continue going the same speed that you were before, in the same direction. If you were to continue flying away for some time, the greatest speed relative to the center of the ride would be the origional tangential speed. In the case of the earth, that's ~1050 mph.
Even more random, but a lot harder: Isolate a single quantum dot, and measure the spin. +1/2, -1/2 for 1,0. The quantum world is purely random, unlike Lava Lamps that just look like it.
I don't know about you, but I don't want bugs eating nuclear waste. I want it locked up in a deep cave, not being spread around by insects!! Unlike with some chemicals, you can't make nuclear waste go away through any biological mechanism, it's a nuclear property, not a chemical one. It would just make the bugs way more radioactive. It would probably kill them, but not until they have a chance to spread it around. An exception would be if it was a bacteria/fungus that ate it and turned it into a form more easily buried.
Once a hypersonic vehicle has accelerated to more than twice the speed of sound, the turbine or rockets are turned off, and the engine relies solely on oxygen in the atmosphere to burn fuel. When the vehicle has accelerated to more than 10 to 15 times the speed of sound, the engine converts to a conventional rocket-powered system to propel the craft into orbit or sustain its top suborbital flight speed.
Also notice this:
NASA's Space Launch Initiative, managed by the Marshall Center, is working to develop the technology for a second-generation vehicle that could lead to a replacement for the first-generation Space Shuttle by 2012 --
I don't think that the shuttles are going to last 10 more years... they're already cracking, who knows what else might happen by then. This project should have started a long time ago. The budget is $700,000,000, which is cheap compared to the repeated launch cost of the overly expensive shuttle fleet. I'd say that it's a worthy investment.
4MB might be accurate for a 128 kbps MP3, but if I had that much stoarage I'd sure as hell have a lot better quality than that. Hell, I'd probably use CD format (or better).
And 1MB of video/min??? I'd use HD res, and that is sure as hell a lot more than that. The LotR divx rips I see are ~ 1.4 GB. They look good enough, but if you really let it loose I would perfer a 50 GB version. That's only 20 3 hour movies. See, not that much. Hell, we may even start storing movies as holograms, and then you have to store phase and polarization date along with frequency! Or if you want true 3d, you would need depth info for each pixel. Whoa...
And they would be good for transfering around scientific data. As we speak, I am working with 330 GB of data from FermiLab. And that's only one type of particle, and only since this Janurary. It took 4 days to transfer from there to here (~150 miles away). If they could burn it on one of these disks, then drive it down, that would be a hell of a lot better.
Yes, that's the way it always goes. Whenever there is an ICBM or SLBM test/launch/whatever, other countries are always notified to avoid any 'mishaps'.
I heard a story about an incident around 10 years ago in which a satellite was launched off of the coast of Scandinavia, and it was headed roughly towards Moscow. The rocket had very similar flight characteristics to a Polaris missile, and since it was launched from the coast, it looked to the Russians as if it had been launched from the water. Yeltsin crapped his pants and nearly pushed the big red button (he was a bit drunk I think). All ended well though.

spots
No spots (but close in)
2 small spots
no spots, but quite funny
