Re: Machines replacing bank tellers?
As to Ayn Rand, I appreciate her philosophy and writing, it is great, but I never needed it to reach my own conclusions decades ago. I only read her books a few years back after hearing so much about them. She was a great philosopher AFAIC, a pretty good writer as well, but the ideas were always here, with or without her books. As to violence - that is the argument of the collectivists, not of the individualists.
Rand was an armchair philosopher and a terrible writer. Her characters are unrealistic cardboard-thin mouthpieces for her screed. She showed very little insight into human nature and the complexity of political and economic systems; she just painted everything with a broad Aristotelian brush.
That said, her books are entertaining and appeal to people on an emotional level. They may be a good starting point for a passionate student of philosophy to consider deeper issues.
I just don't think she needed to take 1000 pages to retell the story of The Little Red Hen.

Re: Rose tinted glasses
Have you actually read Smith's Wealth of Nations? Good book, but it's definitely NOT a proto-Libertarian screed in favor of capitalism or free markets.
No, that would be Atlas Shrugged.
Ayn Rand took 1000+ pages to retell the story of The Little Red Hen - a Russian folk tale, interestingly enough.

Wrong story. Little Red Hen is about pulling your own weight.

Re:RTFA this time
Your muscles may need a few weeks to build back up if you haven't been exercising them, but chopping wood with an axe isn't a hotbed of technological innovation.
Your hands will blister long before your muscles get sore. Get a nice pair of leather work gloves, and get them NOW. When civilization goes to shit, it will happen much faster than you think, and you won't be able to rush to Walmart and buy what you need. The shelves will already be empty. Try to be like The Little Red Hen, and plan ahead.

Re:Slang is never moronic
It makes it look like the sentence was cut off because there was a trailing verb.
It didn't to me or anyone else who knew that meaning of the word compute. It's not like there are no other verbs that are also nouns.
There are perfectly good nouns that would fit that spot and actually be descriptive.
Cough them up. You can't just say that is so without an example you perceive as better. I see nothing wrong with using "compute" in that way.

Re:how about more people?
Australia isn't like the US, which is criss-crossed with rivers even in the desert areas.
The rivers on the east coast, where the population is? Mostly too short/small to even appear on that map.
The north & north-west? Not desert.
Pretty much everything west of the Murray-Darling? Desert. The ones marked 51-57 on the map are seasonal, and flow only every few years.
Much of central-southern NSW, between the coast & the Murray-Darling? Already irrigated through "water [piped] in from all over the region... going over mountains and through valleys". Or, more correctly, "piped through mountains".
The Murray-Darling itself? It already mostly is "just a trickle by the time it reaches the ocean". Without the 2 dredging machines that run 24/7, the mouth of the river would close up and cut it off from the sea.
Despite having an area very similar to the 48 contiguous US states, Australia has ~50% more desert area (1,350,000km^2 vs 900,000km^2) and much much much less water.
So, no, there's not much water in Australia. It's not considered "the driest continent on earth" for no reason...

Re:Nein.
Hmm, "I have a dream" speech, 1963. 70 years after that would be 2033. So it would still be under Copyright.
Correction, the expired time does not count from the time he made the speech, but it is the time he died which was in 1968. That means the 70-year term would start from 1968 (and ends in 2038).
Copyright in a work created on or after January 1, 1978, subsists from its creation and, except as provided by the following subsections, endures for a term consisting of the life of the author and 70 years after the author’s death. (page 3)

Re:Missing the point.
... Edison didn't just think, "Hey, I could put a filament in a jar and run electricity through it to make it glow" and patent that. He actually did the work to make a light bulb, and it took a lot of trial and error. It was not just a mental process, but a physical process.
Edison did not come up with that idea. He stole most of his "inventions" from other people and claimed them for himself. http://www.enchantedlearning.com/inventors/edison/lightbulb.shtml

Re:One word....
Contamination. 'Nuff said.
Obviously. I'm sure they never accounted and corrected for that possibility. After all, it's not like these people are the type who would know anything about basic experimental science or anything.
Sometimes even the researchers think it's contamination, but the story's too good for journalists to pass up. A memorable example:
"Scientists at University of Alabama sequenced a 130-nucleotide long mitochondrial DNA sequence from dinosaur vertebrae, and found that it was 100% homologous to mitochondrial DNA from turkeys. However, the scientists themselves 'remain quite sceptical of our own work' and noted that they had been consuming turkey sandwiches in the laboratory."
Even though the triceratops-turkey 'finding' was never published and eventually dismissed by the researchers, the false result was leaked onto the internet, where it can still be found today.
This RNA synthesis paper, however, has no such caveats.

Re:Refrence for Mecury day
Mercuries rotation is synchronized with its' orbit in such a fashion that the same portion always faces towards/away from the sun.
http://www.enchantedlearning.com/subjects/astronomy/planets/mercury/
"Until 1962 it was thought that Mercury's "day" was the same length as its "year" so as to keep that same face to the Sun much as the Moon does to the Earth. But this was shown to be false in 1965 by doppler radar observations. It is now known that Mercury rotates three times in two of its years. Mercury is the only body in the solar system known to have an orbital/rotational resonance with a ratio other than 1:1 (though many have no resonances at all)." -
34k square kilometers...
That is roughly equal to 13,125 sq. miles - Larger than the state of Maryland, among others. (according to http://www.enchantedlearning.com/usa/states/area.

I am all for new energy ideas. A thesis of mine involved a solar tower placed on Staten Island, NY's Fresh Kills Landfill. This, however, sounds even *less* practical. -

Re:Fe fertilizer -8B tons C, Fossil fuels +4B tons
Oh yeah, that's right... too many global warming chicken littles out there are going to have egg on their face if atmospheric C is reduced to pre-industrial levels and global temps are still rising thanks to the simple fact that the sun is getting hotter.
And the sun's temperature has absolutely NOTHING to do with heating the earth. Throw water outside of the space station, and it will freeze pretty darn quickly.
Also, our sun isn't heating up, its cooling down. It happens to all stars as they are. If it were heating up, it'd be looking more blue than red. -
Re:Alice?
After the female names run out, they use letters from the Greek alphabet. (alpha, beta, gamma, delta, epsilon, zeta,

Actually, they don't use all the letters a-z, Q U X Y Z are not used. That throws your math off a bit, methinks...

Heres the answer
http://www.enchantedlearning.com/inventors/edison
/ lightbulb.shtml
he first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.
In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.
Lewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.
In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world. -

Re:PlanetI say just blow up the moon, that little bastard is just slowing us down.
Actually, to speed things up, you'd need to reel it in a bit. As the moon pulls further away from Earth, the Earth's rotation slows. A billion years ago, days were only about 18 hours long.

Re:Conservation of energy?
Sun heats the land, air and water unevenly which makes wind (read more). Wind blows the water which makes waves (read more). Waves bend the joints between the floats, which causes fluid to be pumped, which turns generators, which makes electricity (read more).
So your thinking is correct -- there's no such thing as a free lunch. If the energy ever stops coming into this system (i.e., the sun stops shining), we've got big problems...

Challenges facing researchers
Having participtated in small scale ecology studies, I would guess that these senors will raise many more questions (which would be a good definition of the "new windows") than answers. Population ecology and the evolutionary biology that ties into it is a field with many more 'big' questions than most people realize.
In most of the primary literature I cover, for every possible cause of a behavior (such as migratory routes) that is eliminated, another 2 consistently appear (seriously). I think we will see some very interesting questions, rather than any definite answers (at least in the short term). I would definitely like to see this used with the arctic tern.

Re:Percentages
18% isn't bad considering the logistics. The US is nearly 100x larger in area than South Korea...
South Korea - http://www.eia.doe.gov/emeu/cabs/skorea.html

US - http://www.enchantedlearning.com/usa/states/area.s html
Population 293m
Area 3.5m sq. miles (2.9m continental)
I wonder what the percentage would be if we only accounted for metro areas like Seattle, New York, LA... while I'm sure it's nowhere near 73%, I bet it's well above 18%. -

A look at solar.
How viable is solar power? I was asking myself this question and here's the numbers I came up with.
In 2001 the USA used 96275 trillion BTUs of energy that year. This comes to 3.22 trillion watts.
Now there are about 295 million people in the US, so this comes to about 11Kw per person at any given time.
This means each person uses is responsible for 262 Kwh of power per day.
Now lets say that square meter of sunlight provides 1 kw of energy on average and the average area gets 5 good hours of sunlight per day. Looking at this chart, you can see that this assumption isn't too far off.
The typical solar panel is about 30% efficient. This means that for every square meter of solar panel would render 1.5 KwH every day.
This means that each man woman and child would need 174 square meters of panel to be responsible for all the energy made and used in their name!
If every person in the united states of America put up solar panels. We would have over 51 billion square meters of panel, that's close to 20,000 square miles of panel or the equivalent of covering most of over in panels.
Now these numbers account for all energy used both domestic, industrial, and exported. Also these numbers do not account for the added or lost efficiency of converting systems over to pure electrical power as opposed to other energy processes like those used in the internal combustion engine.
I left the links to my math in just incase I botched anything. -
Re:Institutional racism
I think you're wrong about that. Africa is big, bigger than either North America, South America or Europe, but not bigger than all of them combined. Here's the first page that came up on my google search.
Africa - 30 million sq. km.
N. America - 24 million sq. km
S. America - 18 million sq. km
Europe - 10 million sq. km
Since you actually said Africa is bigger than the Americas and Europe combined, you're saying 30 > 24 + 18 + 10, which is not true. The kindest interpretation of your statement is that you meant to say Africa is bigger than South America and Europe combined. That's true by a 7% margin. -
Re: 51st U.S. state
And given the common feelings expressed about Bush over here that's a few more electoral college votes for the Democrats. According to the US Census in 2000 the UK has the about the population of California, Texas and Nevada added together (UK Population is somewhere around 55million). Even England alone has over 50million so that's about the same as California and either Texas or New York. Should be worth a few Electoral college votes.

Thomas Edison is analgous to the head of the sony division that used Russel's patent at Sony; he did not invent the lightbulb.

Your reference proves my pointIt's up to you to provide the references to make your case; demanding that others disprove your unsupported claims is just a way of being a jerk. I could spend a large part of the day fisking your post, but as I've got better things to do I'll restrict myself to two points.
- The National Biodiesel Board explicitly says that its production capacity is only 150 million gallons per year, with another 200 million potential. At the limit this is less than 1% of road-diesel consumption and about 0.6% of total distillate fuel consumption.
- US production of soybeans in 2004 was 3.15 billion bushels. At a yield of 11.5 pounds per bushel and a guesstimated 7 pounds/gallon, the entire US soybean crop would produce 5.18 billion gallons of soybean oil. You would need roughly 7 times as much production to replace all over-the-road diesel and 12 times as much to replace all distillate fuel oil consumption; I'm not going to waste the time to calculate what it would take to replace motor gasoline (that's your homework, and you're flunking).
Total US acreage of soybeans harvested in 2004 was roughly 74 million acres, or 116,000 square miles. 12 times this is about 1.4 million square miles. Total area of the USA is 3.5 million square miles, so you are talking about planting another 40% of the land area of the USA in soybeans (over and above the area already used for other crops) just to replace distillate fuel oil use.

Interesting radial velocityLet's see.
1 million RPM at the diameter of a dime.
An American dime has a diameter of 17.91 mm.
At 1 million revolutions per minute, a point on the edge of the turbine blade will travel:
10**6 * 2 * pi * (0.01791 / 2) meters per minute
or
56,265.9 meters per minute, or 937.8 meters per second.
The speed of sound at sea level is 340.29 meters per second.
So this thing's blades will have a tangential velocity of mach 2.76.

This one's a whole lot closer..According to Earth Speeds, the Earth goes around the Sun at approximately 18.5 miles/sec, or 30 km/sec. In six hours the Earth will move 400,000 miles or 650,000 km around the sun. The radius of the Earth is roughly 4,000 miles or 6,500 km. So in six hours the Earth moves about 100 times its radius.

Re:For a LIMITED TIME only
No, but you seem quite willing to unequivocally state that economies of scale make it impossible for them to do so.
No, I'm just saying that Apple's decisions are understandable. Making a profit off of a large number of individuals is a VERY difficult thing to do. It's not a risk that Apple needs to take, so they don't.
Why do you keep assuming that Apple would provide the same quality of service to individual artists with no track record as they do to labels?
In this case I'm not. Every time you involve a human into the process, the costs go up substantially. After credit card fees and the amount that Apple sends to the artist, Apple may not make more than 5-10 cents per sale. At 10 cents a sale, you're going to have to sell at least 20-40 copies to cover the 15 minutes it takes for an $8/hr support person to answer their question.
What do you suppose happens when an unknown developer with a free ADC account has a support request?
I suppose that Apple has already made significant margins off of his purchase of a Mac, and will make more money off of his OS X upgrade purchases, then will make even more money from all the users who flock to their platform because of the software that the developer wrote.
This is the house that Jack built... ;-)
which sits in the input queue until the intern assigned to handling unknown artists gets around to pulling it up and checking it before passing it on to the iTMS.
Which again involves a human. We'll again assume that he's paid $8/hr, but we'll lower the time to respond to 10 minutes. This tacks another 2-4 sales per song onto the break even costs.
I do have to acknowledge that you have helped me come to this realization, and I have to thank you for that.
