Comment A word about Neanderthals (Score 1) 112

Did you know that Neanderthals had bigger brains than we do?
Do you know why? Because they had a working memory!

"Researchers at the Massachusetts Institute of Technology are trying to push 3-D printing technology even further. Their goals: create whole working machines and perhaps even buildings. Thus far, 3D printing has been used to make shapes of plastic or metal that can be assembled later. "

Right. How about this:

Comment Re:Don't let One Distributor Control eBooks! (Score 5, Interesting) 450

This is clearly a form of censorship, but it's not an illegal one. Amazon has a right to choose what they carry in their stores, just as any other store does.

There is a worse form of censorship happening in our schools that very few people seem to be aware of. I discovered this when my daughters collaborated to write a book. They are in first and third grade, and when the box of newly printed books arrived, they proudly tried to donate several copies to the school library. The school rejected them.

It was not because of content. The librarian and some teachers all read the book and thought it was fine, and a great example of accomplishment for the other kids. It was not because of price -- we were donating the books. The problem is, the school district only allows books from a specific set of publishers, and since this book was self-published, it could not be allowed in the school. I inquired about the publishers, and there were only three on the list (Scholastic being one, and I'm sorry don't recall the other two.)

Essentially, the schools don't have to censor anymore, they have outsourced that function to a few trusted publishers. In our case, this is a district-wide policy, other districts might be different.

I have a busy life and didn't have the time to become an activist for open libraries in the schools (but I truly wish I could). Instead, I managed to get the kids' book on Amazon and B&N (although not in an e-book format -- It's a picture book that doesn't migrate well to those devices.)

Regarding Kindles, distributors and censorship - the device is not totally dependent on the e-store. I have versions of my daughters' book on my own kindle and in Ibooks too. The formats for publishing on those devices is pretty well known (epub. mobi, pdf, etc.) Distribution is the problem, but only for the technically challenged who can't be bothered to manually transfer the title onto their device - even when it's as simple as sending an email (a service Amazon provides for their Kindles -- it's a slightly bigger challenge for iBooks, but only slightly. I don't have a Nook...)

But I can't hack into my kids' library so easily -- other than to provide books at home for them too. Is there a better solution to this problem? Ultimately, I don't think so. Does anyone have a different opinion?

Comment Re:Why do we need more efficiency (Score 1) 570

"The solution is to get our population growth under control"

Thomas Malthus said the same thing over 170 years ago. He was right at the time, but ultimately he was wrong. (Research Malthusian Catastrophe) He failed to take into consideration the effects of technological innovation. Specifically, the Industrial revolution and the "Green" revolution which both saved the world from massive famines.

GM crops may be our next stepping stone, but we may not need it either. Review all the wonderful research of Hans Rosling (Watch the videos an Ted.com) the answer is clear. The best birth control is an educated girl. The best way to control family size is to control infant mortality, and that is best accomplished by an educated mother. The best way to bring about education reform and population control is through economic development, which is best accomplished via education... I'm sure you can see where this is going.

It's not speculation. It's been done. We even did it here in the US with the Tennessee Valley in the 1940's.

Not only that, but educated kids grow up to be problem solvers too. Let's make them part of the solution, instead of part of the problem.

What programs do we need? Only one, Education.

About midway through this hour-long podcast, Kelly describes an experiment where they took a 100 year old Montgomery Ward Catalog, and managed to find everything in it still being manufactured somewhere.

I myself still manufacture ancient Catapults and Trebuchets, -- http://www.rlt.com/ -- both small model and full-sized machines. (Fortunately, I was NOT the maker of the drug launching catapult found at the Mexican border that was in the news recently.)

Comment Re:Patents (Score 1) 325

Nope, it didn't work 50 years ago either.

I'm a toymaker, and I had what I thought was a novel idea for a toy windmill. I had no intentions of patenting anything, but searched the patent database to make sure I wasn't infringing on anyone else. Sure enough, there was an application dated 2007, and an actual patent from another person dated 2005. I put my project away for a year, but on hearing that the patent office doesn't really check for prior art, I decided to do it myself.

I found more patents for virtually identical mechanisms, right down to specific gear ratios, dated 1986, 1933, 1915 and 1890. It gets better. Cornell university has a working model of the thing, made in 1827. I don't see how using a chain drive vs. mesh gears vs. push rods, or using six vanes instead of four vanes makes it a different invention. All these machines do exactly the same thing, and all are patented as windmills or machines used to convert a moving fluid to energy.

The system has always been broken. It's just more visible and more abused now.

I'd offer references, but my records are in the other office. (sorry).

Comment Who watches TV anyway? (Score 1, Interesting) 180

Hey folks, we can't afford to watch TV anymore. Seriously, think about what would have happened if Thomas Jefferson, Isaac Newton, Albert Einstein, et al, spent their evenings vegging out to a boob tube. We've got some serious problems to solve! Global Warming, The end of fossil fuels, the looming threat of water shortages, population pressures.... Who's going to solve these problems if we're all catching up on The Amazing Race to Wast the most Time? Come on! If you can't do the chemical engineering, or nano-technology, you can at least help the kids get interested. How about improving education? Getting politically active? Raising public awareness? Not sure if the problems are real? Then put a bullet in your TV and go do some real research. Give yourself an education before you put on the apathy hat.

The house is on fire, are we just gonna sit around and watch it burn?

Google TV is an evil thing. Truly.

Comment Re:Shut Up, Former Astronaut! (Score 1) 508

Yeah, I didn't expect my position to be popular, and I'm not saying Neil was a bum either. But he had a higher calling, and he rejected it to wallow around in his own humility.

Sure, as a teacher he was an inspiration to one classroom. But as how many more engineers and scientists and manned missions to the moon would we have had if Neil had allowed himself to become the celebrity we all wanted him to be?

How many kids went around wearing one silver glove and "moonwalking" instead of flying model rockets and learning about the planets?

How many kids would be wearing one silver glove and moonwalking if Michael Jackson had quit the Jackson Five to teach a choreography class somewhere?

Neil was the first person ever to step foot on a non-Earth ground. That's what it's all about. Second place is always a shadow of the first, and third barely counts at all. Neil had the ball, and he put it in his locker and went home.

Bad boo-boo waddy.

Neil Armstrong. What a disappointment he was. The first man on the moon, came back and disappeared into virtual anonymity.

How much farther would the space program be now if "don't bother me" Neil had instead stepped up to become the real celebrity he could easily have been? What if he had gone on to build and support his already dedicated fan-base, inspire and fascinate the kids and the public at large, making it easier for the politicians to actually fund space exploration and research?

But no, Neil dropped the ball. He SCREWED THE POOCH on the space program and left a vacuum in the celebrity-sphere that the public needs and wants to look up to and idolize. Who filled that space instead? Michael Jackson?

Neil. It's too late. You let us down. This policy is just as much your fault as Obama's. Neigh, more so. Go back to your little cottage and wallow in your privacy. You had a job to do and you didn't do it. You're fired from being my hero.

Comment Re: Faster Than The Other Side (Score 5, Insightful) 254

I have first hand experience with this. I used to employ two skilled carpenters to cut wood all day long. For the cost of one year's salary for those guys, I bought an automated CNC machine that does everything they did, and more, and has been running virtually non-stop for a solid three years.

Sounds awful when I stop there. So then what happened...

My product's quality, consistency and reliability shot up dramatically, Tolerances went from 1/4" to 0.005". My customers noticed, and then my sales shot up too. So my employee count went up to handle the new order volume. I have employees doing jobs that didn't exist when I started this business ten years ago. And now my employees get to work in an air conditioned office and don't have to worry about cutting their fingers off with a table saw either.

So, because technology killed two jobs, I'm better off, my customers are better off, and I was able to hire more employees who are also better off.

When a textile worker was complaining about his job going to China (in the news last year), an astute interviewer asked him "Do you want your kids to grow up to work in this same sweaty factory, breathing this lint filled air?" Of course, the answer was "No.", so then, why not let the job go to China, and teach your kids to embrace the innovation and change that will be so inevitable in his lifetime? That's the value of Science Fiction in my opinion. Once a kid gets his head around it, he understands intrinsically that that "different" is natural, and change is normal. He has to change his world-view to get into the story, for most of the stories he reads. That's good practice for living in any future, especially your own.

I grew up on a steady diet of science fiction. I'm 50 years old now, and I've changed careers in every one of my adult decades. It has always been a good thing for me too. Follow-up studies consistently show that 95% of workers who are laid off get better jobs at higher pay within two years of being laid off.

By the way, here's how the economy really works -- It's not "supply and demand" as the old school used to teach, it's really all about production and consumption, which is subtly different, but in a very important way. A healthy economy is driven by production. Production is driven by consumption. Consumption is driven by innovation (think iPhone, Blu-Ray, etc.), and innovation is driven by education and imagination. If you want a healthy economy, invest in education and support the arts. Give a kid a Kindle stuffed with a thousand books (there are literally thousands of free and nearly-free books for the kindle on Amazon, including the HG Wells collection for $0.99, etc...)
