1) WOZ wasn't the "vision" guy but a super engineer.
2) WOZ lost some of his mental capabilities in a near-fatal airplane accident. He cant really concentrate long enough to repeat his fantastic inventions. He has a good heart and tries to help people.
Radio sensors record the full waveform so you can cross-correlate the raw signal to create a large synthetic aperture. Almost all optical telescopes just record intensity without phase, so you cannot synthesize large aperture. A few telescope sites send optical over wave guides for analog correlation. This works for optical telescopes within a few hundred meters of each other.
Government officials have noticed that wildness permits and park attendance has been dropping the past couple decades. Travel costs and fees haven't increased on an income-adjustment basis. Plus with the increased interest in green and ecology you'd thing people would go there more. The most believable reason offered is that young people are so wired into phones, the network, games, etc. that they dont want to be off the grid for the time it takes to visit the backcountry.
One of the professors who implemented this was a classmate of mine and we talked about this several years ago. MIT's big initial concern was cost. Lab space takes more room than lecture hall seats. Plus you have run the class much more often to keep the lab size down to manageable numbers. Combined this is almost an order of magnitude of more capital and labor than your standard lecture course.
The NY Times article pretty much lists the advantages. Foremost is an improving the pass rate from 85% to 95%. Second is students learn and retain the material better. Freshmen courses are the basis of subsequent coursework. Third is more efficient grading. Students and professors are being given automatic feedback. You dont need as many problems sets and exams. (A disaster for the MIT tradition of showering freshmen on the night before the first physics midterm:-)
There are hybrid solutions to make lectures more interactive. Something as simple as clickers, like they use in TV game shows, to give the prof immediate feedback and keep students focused on lectures. And this costs on $50 per student.
Back in the 70s computer scientists had this vague notion of the "next step" after compiled procedural text-based programming. Something like FORTRAN, C, LISP were called third generation after machine language and assembly. One approach to fourth generation was "visual programming". Some work had been done on flowcharts that would compile themselves after you drew them - severely crippled by the inadequate computer graphics of the 1970s. Then the revolutionary "table" paradigm of Visicalc came along. Tables gave a visual feel for the connectivity data and formulae. The spreadsheet program provided pre-programmed elements such as display, I/O, and control flow. The user just added data types and formulae. Plus it was readily implemented in the text terminals of the era.
Computer screens were not practical until you could store the ascii character bit pattern in affordable read-only memory - thats about 2240 bits of memory. A bit of memory cost over a dollar well into the 1960s. Intels second hit product circa 1970 was the half kilobit ROM debuting at about $100 and rapidly falling there after. That meant computer terminal prices feel to a $1000 by 1974.
And I was musing that her dream of man creating life is still unfulfilled two centuries later. Stories about magician animating the non-living are as old as man, but hers became iconic.
The ultimate proof of not needing a deity or special substance for life (or mind too) would be able to construct it out of raw ingredients. I 99% believe this possible.
Life evolved on Mars first, because it reached geological stability sooner. Then it infected Earth via Martian meteorites. Dozens of meteorites from Mars have been found and that is probably only a tiny of percentage of those which have reached Earth.
I recall the Stanford Math library betting Dr. Dobbs. in the late 1970s. It was more like a newspaper, or a "zine" what self-published magazines were called then. It was loosely associated the the homebrew computing clubs popping up in places.
Shotgun sequencing depends heavily on supercomputer. Thats a thousand-fold every 15 years right there. Multiply that by more intelligent software, understanding of genetics, and sequencing hardware, you may be squaring that rate.
Forensic genetic identification currently uses about 60 important genetic markers. Thats good enough to convict in a court law since the the chance of a duplicate may be less than a billion to one depending on marker combination.
Although humans differ from one another in about 0.1% base pairs for a total of 3 million, the number of difference that describe human variability may be vastly smaller than this. First you discard non-coding DNA which gets you done to 30,000.

Two are still minors. He will spend some time with them.
Richardson, Geithner, TV scandal ...
Even "Whitewater" Hillary starting to look good in comparison.
That was an original constraint of YouTube. That could make it worth it. If you can't say it in five minutes, then you can't say it.
They are probably contaminated with every substance under the sun. Got to rule out the nicotine, the energy drinks, the booze, the hard drugs ...
1,600 kwh per month is gargantuan.

They are fantastic - million contrast ratio for page-size screen. However its still over $2K at the lcoal Sony store.
I'm surprised no one mentioned MIT's long-running "Charm School" designed to teach nerds table manners, basic fashion, and dating tips.

Since many of them dont learn to drive until they start here, if ever.
Just copying isnt going overtake a market someone else dominates.

I dont know what all new gadget will be, Kurziwell has better ideas of this, but many things will appear fantastic to myself of 2009.
While they made billions for their investors. Stanford couldn't be bothered with student projects.
Now I'll have to listen to typing too!
Does anyone flush a few extra times to try to embarrass the cell phone yakker?
