Yeh, there is cheap land out in the middle of nowhere. The problem is getting to it, and once you do, having stuff shipped to it to do all your homebrew engineering. Then once you decide to stop living in your vehicle, getting building supplies and crews to it is another problem. I don't know what the price threshold for that kind of land is, maybe lower than $500 per acre.
Because in a laser system you would have 3 lasers scanning to produce each pixel. So the pixel size would only be limited by the width of the laser beam. And you would have a single high speed mirror for each laser. So, the limit on resolution would be how fast the mirror can turn between projecting 2 discrete pixels. The mirrors could be whatever size you want, 1" x 1"... whatever since their size does not directly affect the resolution (indirectly their weight might affect the control ability which would in turn affect the resolution).
Whereas, for DLP more mirrors of the same size on a single chip increases the probability of a failed chip. And, decreasing the size of the mirrors to fit more on a single chip requires more development, which increases the probability of a failed chip (until some point in time since probability of failure usually decreases with time for developing technologies).
When looking at property out in the country, water rights are a common issue - who has rights to use the water from the river/stream? Because if you move in and start using water upstream of someone else that has been using the water for 100 years on a farm, then they'll get mad. Anyone have any idea if water wheels and power generation are subject to water rights?
But imagine if someone did develop a laser projector. The resolution would only be limited by the control system (mirrors, whatever) for the laser. You could have a near-infinite resolution system by simply creating finer and finer controls, rather than trying to pack more mirrors or more pixels onto a smaller and smaller chip. Imagine a 16000 x 9000 resolution, 20 foot diagonal screen. That would be awesome. Now you just need to find some source material at that resolution... a room full of super computers rendering quake should do fine, heh.
As well, since you are not working with a planar source surface (ie the LCD panel or DLP chip in a projector), you could mount the laser source at the focus of a semi-circle and get a panoramic display. The calculations would be straightforward, just a series of transform matrices.
I actually prefer to get up and walk around, go outside (no windows in my building, and it feels like no AC), stretch my legs, etc. I probably spend 5 minutes out of every hour walking around to get water, food, go to the bathroom, or get some fresh air.
Yeh, and I felt bad spending 10 minutes a day reading the latest headlines related to my industry... then I saw people playing video games (FPSs... seriously), playing solitaire, and talking on the phone with their friends 3 or 4 hours a day or doing personal business on the phone.
I think that's the point, you're taking the class because you're required to, but you don't want it to affect your GPA. Hence the pass/fail option. Otherwise, what would be the point of the option if it did affect your GPA?
Seriously, that sounds like an awesome program. The only problem I can see is the cost, how much? Because it sounds fairly expensive. Docs to teach elementary kids... kids bussed in from all over the county...
Also, outside projects are extremely important. Nothing fosters learning and supports existing class material like applying it to something in real life. Robotics competitions, bridge building, rockets, etc for the math and sciences. Organizing, producing, and funding an original play, event, or charity for the social sciences and humanities.
Another problem with the grade system is that when someone is failed, they lose contact with some of their existing peers. And, they are probably more likely to cause problems with their future peers. But with a level system, a student's peers might be independent of a "grade" since the student could still interact in the classes that they don't fail. Or, since the levels might become so varied anyhow, peer interaction would occur primarily outside of class.
It is now the student's responsibility to ensure they reach level 8 in all their courses to graduate. And they are motivated to do so because of their peer group's advancement. They don't want to be the "loser" that is still in level 4 math when everyone else is at level 8 math or something.
Written exams are the hardest. A 5 choice MCQ gives you a 20% chance of getting the right answer with no knowledge of the subject. A written exam gives you (maybe) a 1% chance (for randomly pulling stuff out of your ass and combining numbers). Otherwise why would advanced programs require oral examinations for admittance? Why not just hand out an MCQ?
Still, many MCQs are done poorly and some even leave much ambiguity in the question/answers. MCQs are just an easy way out for the teacher or professor, nothing more. When you have a lecture hall with 200 students taking an exam, I can understand why an easy way out is desirable. However, for a high school teacher or more advanced classes with smaller numbers of students, MCQs are not acceptable. If you have 30 students in a class, you should spend the time to hand grade written tests so that you can give individual feedback to each student.
That's the great thing about math. If your reasoning is correct, you'll get the right answer.
That's where you're wrong.
He said that if your reasoning is correct, you'll get the right answer. He did not say that if you get the right answer, that your reasoning is correct.
Yet we still received partial credit, heh. The point was to see if you were making progress in the learning process. A right answer that contained thinking flaws in the method received 0 credit (this usually consisted of someone randomly combining the given numbers for the problem). A wrong answer with the right method usually received 1/2 credit. And the right answer / right method received full credit. (Of course there was a near-infinite sliding scale inbetween those three values for multiple-step and complicated problems.)
However, in physics it was easy enough to make the problem slightly more complicated such that anyone who didn't know what they were doing from the start (randomly combining numbers) would never get the right answer, yet people who knew what they were doing would not get thrown off by some obscurity.
I would do that, except I like the discovery channel and food network. And you can't find programming from those channels on bit torrent. And comcast charges you $20 more per month for internet if you don't buy cable. It's kind of sad to consider what I pay for maybe 3 or 4 channels.
Similar situation here, just not as big. I played sports and did a lot of physical work outside of school, so I stayed in shape. I steadily grew from 5'4" and a lean 140 pounds in 9th grade to 6'0" and a lean 180 pounds in 12th grade. No one ever bothered my in high school (except maybe as a freshman from a larger senior, but I don't recall).
Maybe we just need to get the nerds out there in a physical program? I played sports because there was a physical requirement to graduate: either gym class or a varsity sport. And I was already tight on room in my schedule for math and science classes, so why waste the time on gym?
Do parents really get that riled up nowadays? I've been out of high school for a little while, but not THAT long (less than 10 years). And I recall discussing all sorts of topics along those lines: pre-marital sex, abortion, illegal immigration, politics, evolution, religion, etc. Perhaps this was without the principal's knowledge, or maybe they just overlooked the situation, I don't know for sure. But my parents weren't bothered by it one bit, perhaps even enthused that such open debate was taking place. And I'm sure these were crucial to developing my current set of critical thinking skills. It was fine as long as the teachers weren't giving us step-by-step instructions for lynching the local minorities.
But then again, maybe my parents were a bit more "old school" than normal. The paddle and the belt were routine punishments in my pre-teen years. Chores were obviously mandatory. Mutiny or any attempt to subvert the family structure was met with threats of expulsion from the family. And the teachers were an authority to be respected as long as we weren't being abused or anything. But despite the strict environment, ideas were free-flowing and encouraged. We played games all the time and were encouraged to take up new interests. We were even given chances to attempt to logically argue ourselves out of incriminating circumstances. The only requirement was that any endeavor we took up must be carried out to completion.
And I think the results were good. My siblings and I are achievers. Everyone has gone to college with scholarships and grants, and made up the balance with their own jobs. The ones that have graduated are employed full time in professional fields, and I would like to think are successful. However, I am socially inept - somehow they screwed up on that one. And we all have our own psychological short-comings, but we're not sociopaths.
So maybe today's parents need to chill out and realize that their kids need to be exposed to the world? If anything, maybe a little wake-up call now and then will prevent kids from turning into those monsters on Nanny 911?... Hitting your mom? Holy crap, you better believe a beating is coming. Just cower and beg for mercy and a second chance.

"Guests of Exceptional Size
All passenger restraint systems, including lap bars, shoulder harnesses and seatbelts, must be positioned, fastened and tightened to allow guests to ride.
Due to rider restraint system requirements, guests of exceptional size may not be accommodated on some of our rides. This may apply, but not be limited to, males who exceed 6'2", and those who exceed 225 pounds, have a 40" waistline or 52" chest or females who exceed 200 pounds or wear size 18 or larger. Each person has different body proportions, so it is impossible to determine exact size and weight."
Even better, go on Tuesday or Wednesday of the 3rd or 4th week they open for the season. The park is practically empty (high school is still in session, colleges might be out though), and everyone that is there is usually in line for the newest coaster (TTD now, or Millenium Force before TTD opened). I went a couple years back, either the first or second yeard TTD was open, and in the late afternoon the line for Millenium Force was so short that they opened the access door between the exit and entrance ramps. As soon as you got off, you could jump right back in line and usually catch the next train. I rode it something like 6 or 7 times within a 1/2 hour. Gemini and Magnum XL 200 were even running with empty seats on trains!
Cedar Point will definitely spoil you though. After attending summer after summer and then moving out of the area, I just sigh when I look at the local coaster parks. They're nothing compared to Cedar Point.

You may be on to something here, but this show would definitely fail. So far I have not seen many people discuss the actual show itself, but I for one found it to be extremely boring and quite dumb. The acting was sub-par, all the buzz words they threw around were just annoying, and the plot line was so ridiculous I just kept thinking "wow, this is stupid". For instance: waking a world-class gymnast in the middle of the night to do some flips on some perfectly-place underground bars... gimme a break, they need to come up with better ideas. I for one am glad this show didn't make the cut. It would have been another instance of sci-fi getting a rep for producing bad shows.
9 am is rush hour over there? Sheesh, maybe you brits need to be less sluggish in the morning. Over here, rush hour is at 7:30 am and I try to leave for work by 7 am to avoid it.
"223 miles per hour -- faster than many propeller airplanes"
Gotta love the editorials. Propeller airplanes built for commercial passenger travel get much higher speeds than that. Example: NWA uses the Saab 340 for pond jumping, cruising speed is over 300 miles per hour. You can't compare commercial train travel to personal airplane travel. Still, even little Cessnas can reach 200 miles per hour.
If governments pumped $200 trillion into alternative energy research and development, everyone would be running around in hydrogen cars or something similar in no time. And does anyone really have any freaking clue whatsoever how a big patch of shade would affect the Earth's fragile balance? I didn't think so. Let's come up with better solutions before we start f'ing around on such a grand scale and then say "oops" when the Earth implodes or something as a result of those actions.
If the US government said they would buy $500 billion worth of alternative energy cars, the motor companies would be all over it. Ford and GM only do $150 B and $190 B in revenue a year. And if not them, the smaller motor companies would pounce on it.
The people who proposed this idea of shading the Earth are f'ing dumbasses.
