Nuclear engines make less sense than you might think because they are limited by the amount of reaction mass you can carry. You might have enough fissile material to run a reactor for a year but only enough reaction mass for a day or so, at the very best, so most of the energy you are carrying is going to be lost.
Solar sails work anywhere you have sun light and can easily work for years.
Having said that I think there is an argument for using small fission reactors to power ion engines. A power plant like that could be used for a flight to Titan. The reactors could be similar to those use on submarines, so the technology would be mostly COTS.
How old is your son? My son had an MRI (investigating migranes) at the age of seven. They used a setup in the children's hospital here with audio through a plastic tube and back projected video. They gave him a choice of DVDs to watch. The picked The Incredibles and he didn't want to come out because the movie wasn't finished.
Its interesting because my nephew was diagnosed with fungal meningitis about 18 months ago. He was otherwise healthy, not immune deficient. He is 15, does well at school and plays sport. A scientist who works in the field told me that treatment for fungal infections is much harder than for bacteria because more things which kill fungus, also kill us.
So far I haven't seen any fungus induced behavior change in my nephew, apart from the normal effects of a brain infection.
"In the future, whether it's entering your home, opening your car, entering your workspace, getting a pharmacy prescription refilled, or having your medical records pulled up, everything will come off that unique key that is your iris," says Jeff Carter, CDO of Global Rainmakers. Before coming to GRI, Carter headed a think tank partnership between Bank of America, Harvard, and MIT. "Every person, place, and thing on this planet will be connected [to the iris system] within the next 10 years," he says.
BURN IN HELL, MOTHERFUCKER!
Well thats his view, and he is a salesman after all. But I wonder about how unique retinas are anyway, and how reproducible retina scanning will be in the long term?
Thats true but here in Australia time out isn't as commonly understood outside basketball. If I was playing tag and I called time out everybody else would keep playing.
My eight year old son plays the usual games in the playground but I noticed that it is now possible to pause them. The way it works in you are running around playing Tag or something and somebody says Pause and everything stops. Its a bit like time out in basketball, but for me it is directly derived from the electronic games they play which generally have a Pause function.
But with sufficient organization, groups of humans can work on systems of comparable complexity to a human brain.
This basically assumes that the problem can be broken into independent sub-problems with interfaces whose complexity does not exceed the understanding of the humans responsible for them, neither of which is at all certain.
I would argue that there is an evolutionary advantage to the brain being structured, because this is consistent with structured encoding in DNA. The encoding in DNA will tend to be structured because this minimises the use of energy and other resources.
Monday this week, riding home on my bike there was this late model VW beetle. Very new in fashionable black with a fake flower on the dash board (I am told they all have them) and an Apple Computer sticker on the rear windscreen. I wondered if that is standard too.
Yeah cable can be great for burst speeds. When I used Optus cable I once downloaded a fairly big file (say 30MG) with wget. The command actually completed before I noticed it had finished. I thought it had failed and looked for an empty file, but it was all there. Must have come down the line in one chunk.
To sum it up, the DNA is just a small piece of the self modifying base code for the first initialization of the FPGA. The way the final FPGA is mapped depends on environmental factors (eg. which agent fired first, how did selection happen, small biases arising from the physical nature of the FPGA being propagated to wild changes in the end result). Thus, modeling just the base pairs is not sufficient as the interactions of the automata from the base pairs must be modeled as well.
True but that doesn't explain why we are so consistent at the hardware level. Why we all experience the same optical illusions for example. Why we all see pictures the same way and appreciate the same music and art. A lot of that is cultural but I suspect that if there was opportunity for brains to diverge much during gestation, then later cultural programming wouldn't work at all.
If anything our brains start out (at birth) more alike than they ever are during their lives.
As humans we hang on tight to things which affirm are superiority over other animals and the universe in general. Part of this is the notion that the mind is something mystical which can't be reduced to simple data processing. So when somebody comes along and claims to be able to put the entire spec for a human being on a microSD card, we get upset.
Even though, as you point out, the entire spec can be packed into an ovum and a sperm.
The structure of a new brain must come from the following sources:
1. DNA
2. The environment
3. The host environment during gestation
But if the "software" comes from the environment (say learning during and after brain development) then there would be more variation between individual brains. We don't see that. Consider optical illusions which work on people from all parts of the world in the same way.

Isn't it wonderful?
NASA built the worlds first solar sails anyway.

This election is really a case of trying to pick a candidate that is the least awful
C'mon its always like that.
By far, Australia has one of the most "nanny-state" governments around.
Sorry you had to watch our TV. I don't. Can you give me some specific examples to back up your assertion?
I don't think the nickname for Adelaide (The capital of South Australia), "The City of Churches" is a coincidence.
Many of their working age people are off in different states. They return to die, hence the thriving funeral industry.
So your nephew most likely can't infect anyone by contact.
Sure, where it is, its hard to see how it could get out, or in for that matter.

Even 4chan scans .jpeg files for embedded RAR archives... how hard is it to figure out that a QuickTime file’s structure is invalid?
Well fine, but that is a specific check for a known attack. How to you scan for all the unknown attacks?

It's synonymous with "Time Out."

I get wireless power from the sun.

it may not be possible for a mind to understand a mind of equal complexity
