Actually fusion really isn't the miracle power source they have made it out to be. Sure, it doesn't pollute, and the fuel cost is almost peanuts. But the reactors themselves will always cost huge amounts of money and still take quite a bit of manpower to run.
However, fusion will still eventually end up somewhat cheaper than other forms of power generation. It just isn't a miracle "too cheap to meter" type of thing.
Those particle paths in cloud chambers are hard evidence. All scientists seem to think so. I don't think the flat tire comparison is valid at all. When we see the particle paths, we see the particles exact effects! It's just like we saw the particle.
BTW, Scenario 1 is _hard evidence_ that there's someone who's letting down tyres in the neighbourhood, scenario 2 is _not_. Are you really sure your 20 year old Lada doesn't have fucked valves?
Well, you are only seeing the effects of Scenario 1 also. Light interacting with the person and your car gets focused strikes your eye in a way to form an image of someone fucking with your car. How do you know it isn't just a big phased array optic screen right there put up by aliens for some reason?
My point is that those paths can only be subatomic particles. Do you have a different theory?
ok can we fix the economy instead? or our education system? i just think all of this is leading to absolutely nowhere in the near future and the money could be better spent doing something useful.
What about the gobs of useless money we spend on our oversized military? What about how we pay farmers to not farm their crops?
If we were only concerned about immediate serious problems, we would not have: Communications sattlites, AMERICA (hey, Columbus's voyage was gratuitus), computers, etc, etc, etc.
If all we are concerned about is education and the starving children of Namibia, we will go nowhere. Humanity will stagnate.
What nonsense, really. Why would a bacteria care about magnetic North? Do they have little maps or something? We could make a fortune selling them nanotechology GPS receivers. Unless they use their little compasses to find magnetic South, which something we as humans rarely hear about. A blatant case of boreacentrism.
Bacteria really aren't affected by gravity. So some use magnetism for orientation. Maybe you should read the article.
Gravitons are a nice way of satisfying a few equations, but they don't really fit in the standard model and have never been even indirectly observed.
Gravitons probably exist. We may never observe them because they interact so weakly. I really fail to see how we could block them. It seems to violate conservation of energy.
"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."
- Albert Einstein, explaining radio
See! See!? Einstein was secretly working on the buttered toast/tabby antigravity research back in the 30's!!!
At those speeds, wings are a hindrance. One finds that the leading surfaces must be made of unobtanium.
One of the ways around this is to use plasma. If you generate plasma ahead of an aircraft with a welding-torch type of thing, you can reduce the drag by as much as 30%. The Russians are using plasma in their next generation of MiGs. (BTW, plasma also absorbs radar)
Another thing is to use carbon-carbon composites. C-C's are very expensive but can withstand many thousands of degrees. They are used in rocket nozzles.
I hope one chunk destroys the Space Needle. Not because I have anything against it, I just think that would be totally cool and a perfect target.
That would be cool. If it kills a shitload of people, you'd get the added bonus of building some huger mermorial in it's place, possibly bigger than the original space needle.
Every once in a while I would send it emails, or send emails from it to myself just to keep it alive.
I have an email account that I use daily, spikehay at yahoo dot com. I never post it on the web, I never give it out to any website, except for trustworthy ones like/. and kuro5hin. I have been using this account daily for 6 months and have never recieved a spam.
Genetically modified caffeine free coffee is the same as regular coffee. It just has the gene that produces the protein caffeine deleted. GM foods cannot change your body's DNA. That is a completely unfounded myth.
GM foods are completely safe unless a poison is introduced (NEW!! Nightshade enhanced brocolli!!!) or an allergen is introduced. DNA codes for proteins. That's all it does. Now, scientists usualy know what protein the gene they are splicing in codes for. So GM foods are very safe.
From what I have heard, a LOT of the current alzheimers cases have been tracked back to the aluminum in our cooking pots and pans as opposed to the old days when they were made of iron.
The reason why there are more alzheimers cases now than there were 50 years ago is not because of aluminum, but because people live longer. According to my sister, a nurse at an alzheimers care facility, most patients are over 85. When you get that old, your brain just goes to shit.
However, these elements may not occur in nature (eg. Technetium) or may have infinitesimally short half-lives (eg. most atomic numbers > about 100).
Actually, technetium has been discovered in nature. Just in infestimally small quantities. Also, plutonium was discovered around a natural "nuclear reactor" in Africa.
Will he really experience a sonic boom? If so wouldn't that destroy his ear drums.
Actually, no. The sonic boom is never heard by the body traveling at supersonic speeds, wether it be plane, rocket, or person. Concorde passengers are unaffected by the boom.
The conical shock waves never touch. At least they aren't supposed to. Now, since a person is thin like a rocket, I am sure he won't have to worry about shock waves.
Right after the USSR went down the tube and the nuke threat was gone we should have bombed the living hell out of them, but noooo,
The nuke threat from Russia was never gone. Just because the Soviets were replaced by a democratic gov't doesn't mean the weapons dissapeared. They still have over 1000 warheads.
We lag behind china in consumer tech, such as laptops and cell phones. Although we are wayy ahead of them as far as cutting edge, non-consumer technology.
One reason for this is that the U.S. culture encourages creative thinking more than Japanese culture. Japanese culture is very rigid as far as work goes. So anyway, we develop technology such as PC's and cell phones because we think more creatively. Then the Japanese take our inventions, improve on them, and make great consumer electronics.
Well, the tests the Wright brothers did took place on a flat spot at Kitty Hawk, so since they were going about 30 mph about five feet off the ground, I'd say the safety level is a bit higher.
The Wright brothers would have been toast if they crashed, most likely. They would have slammed into the ground at 30 MPH with no seatbelt, possibly injuring themselves on such things as the propeller.
With sky diving, the chance of dieing is only 1 in 80 K. Rock climbing is even less dangerous. You are on a cliff with a rope capable of holding a full size van holding you in case you fall. There are 30 million climbers in the U.S., me being one of them. There are usualy only about 10 or less fatalities a year. Rock climbing, statistically, is safer than riding in a car.

I know you are making a joke, but seriously folks....
A reactor operating 220 seconds is not a huge tech leap away from one able to operate forever.

I just downloaded Moz 1.1 Beta just about an hour ago. It's even better.
Really kick ass animals like flesh eating kangaroos and marsupial lions go extinct, while others such as the wallaby thrive.
Yes, and what do you do when you get to the end of the moving sidewalk; get thrown off the platform at 20 MPH?
I dunno, lay down some foam or somthing.

Sure, it does. Think of all those cereal boxes that are "sold by weight, not by volume."
;-)
In the future, they'll be "sold by mass, not by volume."

At 1.68, air friction is not that bad at all. He's wearing a protective suit as well, to boot.
How does a chute become frozen? Last time I checked nylon was already "frozen" at room temperature. ;-P

Did you mean Phoenician? That's the alphabet used in the english language
No. Roman alphabet is correct. Look at Roman inscriptions and look at Phoenecian ones. Roman letters are exactly the same as ours.
Now archaeologists think the alphabet originated in Egypt, then spread to the Phoenecians, Greeks, Etruscans, and finally the Romans.
