I don't know what evidence you are using to draw your conclusions. How do you know that there is no exotic physics yet to be discovered? How do you know there is no way around (travel from point to point in our universe being limited to less-than)/c/?
There is no way you could do a US Presidential election this way.
Maybe. Scale it up in steps. Groups of 12 citizens who are known to each other get into rooms to conduct a vote. One is chosen to take their group's decision to the next level, where 12 group representatives who know each other get together to vote. And so on...you'd only need seven levels of voting to reach the final 12 representatives in the current US voting population.
I'm using a fuzzy interpretation of the Six Degrees of Kevin Bacon game to assume that you could always arrange the representative groups to all know each other. Probably that means that the person in each group with the highest socio-economic status would be the logical representative, since they would be the most likely to have direct ties to other high socio-economic status members of other identical level groups.
I've not fleshed this out logically or mathematically any further than that. I'm also not suggesting that this would work well (or that it would be better than our current system), just proposing that it might be a theoretically possible way to do a US presidential election.

Has Lego Sold Out?
·
· Score: 1
I used to ask for LEGO sets for birthdays/Christmas, and essentially the more motors and gears and shafts and connectors there were, the better. The last set I have like that was the original Lego Mindstorms programmable set. Sure, there were instructions (like there always were), but it was a set filled with gears and shafts and blocks and connectors. I could make anything I wanted out of that (and I did, and I was in college).
If I could still get that kind of set, and not a "Star Wars X-Wing" set, I would STILL be buying LEGOS for MYSELF, as well as buying them for nephews and nieces.
Schools should embrace the new technology available to them. We are now able to produce interactive educational experiences with portable devices, created by the very BEST teachers. Students are able to use the devices at their own pace, studying a concept over and over until they really "get" it. Why have students together, learning at an artificial pace, studying curriculum created by someone who is merely average? . . . Of course, the technology I refer to is the Gutenberg Press (ca. 1440), and the interactive educational experiences are mass-produced "textbooks".
Or it is the postal service and correspondence courses (ca. 1900), Or radio and broadcast education (ca. 1940). Or television and televised courses (ca. 1960). Or mainframe computers and computer-based learning (ca. 1975). Etc. etc.
I think until we have artificial intelligences advanced enough to understand human thought, preconceptions, and learning as well as a well-educated human, actual human teachers with (real or virtual) classes will remain an essential part of education for most people in most subjects. While I am a teacher, I came into the profession through an alternative route, and held these opinions before I ever considered teaching.
About the only teachers that work any significant about beyond the 6-7 hour school day are teachers that must grade essays. So, your myth is already busted.
I teach physics. There are some problems with the statement I put in italics above. I recognize that the facts vary from district to district, but I have also never met a teacher in any district that had a regular 6 or 7 hour day.
Our contracted day is 8.5 hours long, which includes one 22 minute lunch. Technically, I'm finished at 3:45. Almost every day of the week, I am there at least one hour late, often two. There are labs to plan and setup, students who need help, and meetings to attend. If I average an hour and a half of extra time at school, that's already 10 hours per day. I also take work home if I can't get it done after school because, for example, students come in needing help or reassessment. Perhaps on average an extra half hour per night.
If I average 10 hours a day at work and a half hour a day at home, that's about 1880 hours per academic year. That's 90% of the 2080 hours a normal 8 hr/day full time job.
There are also the other professional activities and duties I participate in, such as continuing education, networking with other science teachers and scientists, and keeping current on research in physics and education. I take classes and attend workshops and conferences during the summers. For example, I have spent about four hours per week researching and planning, plus five full days on-site at workshops this summer.
I'm not complaining, I just prefer that people take a more factual look at teaching careers, not the mythical "6 hour day part time job" that many people would have you believe.
Heck, ideally I'd say hold a class-wide experiment once a month or so to figure something out - students work in small "research groups" attacking the problem from different angles, but by the end of the "research window" (days?, weeks?) everyone needs to reach a consensus on what the "real" answer is, with some sort of prize (pizza party? movie break?) if they're correct within a certain margin of error so that they actually care. Then, once everyone has agreed, bring in a professional who can provide a conclusive answer in an understandable manner to verify the results. Not only would that provide a taste of real science, but it would also provide a periodic reminder of the fact that in the face of an implacable universe the best speakers and most inspiring/popular/attractive students generally aren't the ones you want to be listening to if you want to get it right.
Your statement bears some relation to how Modeling Instruction works, although the research/lab experiences are usually a bit more frequent than once a month, at least if the class is keeping up with the expected pace. There is no pizza party, and usually no "professional" providing a conclusive answer. The 'answers' come from the students' analysis of their data and reaching a consensus through group-group interaction.
I'm going to assume you mean any other kind of bachelor's degree, and the answer is still "yes they do".
The Bachelor of Arts degree is also an option most places, and in some colleges it is the only option. "Arts" does not mean paint and clay (necessarily), it means it is a liberal arts degree, in which one can major in any of a number of areas, such as physics, mathematics, chemistry, history, foreign language, etc.
The degrees are usually seen as equivalent, although if you are choosing between the two at a university that offers both, it is typically the people who want to go on to graduate school in physics who opt for a B.S., and more often people who want to go on to a professional degree, teach, or work in industry who opt for the B.A..
Also consider what to do for classes that do not use lecture much if at all. Many modern science classrooms use other methods, such as Modeling Physics. If you were to video my classroom, you would need to be prepared to video student whiteboard sessions, lab demonstrations and discussion sessions, experimental design, experiments, data analysis, lab whiteboard discussions, and extensions such as worksheets, challenge problems, computer simulations and programming.
I think you would need a live videographer to properly record something like my class in any sort of useful way.
I have a NC, and use the boot-from-SD feature to run CyanogenMod7. The original firmware is not rooted (it is unmodified in any way). I updated to the newest Barnes and Noble-skinned OS version in the past week because of the updates you mentioned.
My SD-card still boots up just as it did before, no change. So the update may have changed whether you can root the device itself, I don't know--but it doesn't change the ability to run full-Android from SD card. I'm looking forward to CM9...
Phil Sadow, who was interviewed for the story: 'I don't like the term hacking because it's been portrayed by the media as something evil. To me, hacking is actually very American. Go out to the garage. Take it apart. Make it better.'"
I, on the other hand, love the term "hacking". News media have put a negative spin on the word, but I think we should take it back rather than let them have it. A hacker is nothing more than someone who gets into the guts of things to see how they work and to do cool things with them. Consequently, you can hack anything--computer hardware, software, engines, motors, locks, sewing, knitting, art, math...
Teaching is not telling and repeating is not learning.
Half a century of physics education research is continuing to show that people need to learn the conceptual why just as they need to learn how to use the mathematical model. If they don't understand the concept, the math will be nothing more than a magic black box that spits out numbers for them. Engineers need to understand the concepts.
Science is not just a tool, it is one of humanity's primary methods of viewing and interpreting the universe, along with art and religion (and philosophy, and some other categories). If you do to art teaching what you propose we do to science teaching, people would learn to paint by numbers to reproduce versions of the great works, but would have no opportunity to learn line, or shadow, or structure, or perspective.
You would learn nothing significant about art that way, just as people learn nothing significant about science by learning to plug and chug equations.
What it does not include in any significant amount is lecture. And while I'm not a top level expert in modeling physics just yet, I do my best to keep students engaged in the learning cycle as we go through each physics phenomenon to model, from constant velocity motion through forces and energy and beyond.
I can honestly see using the Khan academy as an aide to students who need practice with the mathematical problem solving that comes after we study a physical phenomenon, but it can't substitute for the inquiry, investigation, experimentation, and construction of various types of models that have replaced lecture.
I think the likelihood that the airport security agent was thinking of the incidental RF emissions from the sonogram's ultrasonic probe is exceedingly small.
There's benefit of the doubt, and then there's...well, it takes a lot more benefit to assume she knew what she was talking about.
I'm in the same boat...or under the same rock. First I've heard of Google Health. I'm trying to decide whether I'll even go read about it, since they're killing it already.
I like your idea of Google Tell People About Things Better. That's an app that they apparently really need to develop.
I had to go to my shelf to be sure, but yes...one of my favorite electronics books, Troubleshooting Analog Circuits, was penned by the talented Bob Pease. I always enjoyed the clever writing style and humor that came across in that wonderfully detailed book. I received it for a review many years ago, and after reading it decided it earned a place in my permanent library.
It is unfortunate that only now have I found his regular column ( http://electronicdesign.com/author/904/BobPease.aspx ). I will enjoy reading through the rest of them, but I will be quite sad to know that he is no longer around to write any more.
He seems like someone who would have been great to know in real life. Godspeed, Robert Pease.
My nearly complete collection of Mims' Engineer's Mini Notebooks, which is never more than three feet from my primary work desk at home, nearly started humming when I read your post. Bravo, and if I only had mod points you'd get one.
Please look into Modeling Physics. It is a research-based physics curriculum that originated at Arizona State University. There are now extensions to chemistry, mathematics, and biology.
It is a strongly constructivist approach to teaching physics, where observations and laboratory experiments (including all phases of experimental design and analysis) lead to mathematical and other models of the phenomena under study. From what I have read of PSSC, some of the positive aspects of PSSC are present in Modeling today.
I realize I'm talking to a school teacher here. School teachers in high schools and elementary schools don't write grant proposals, because that's university stuff.
There are actually quite a number of opportunities to write for grants at the high school level. They are typically for equipment, supplies, or activities only -- such as buying new sensor units, buying binoculars and telescopes to start up an astronomy course, taking a class on a trip to a national lab-- but they are out there.
I received a grant that supported about 80% of the model rocketry supplies my physics class needed this year. The poor state of the economy is a great motivator to locate alternative sources of funding...
There are actually several high-quality physics textbooks available freely online. Check out motionmountain.net and lightandmatter.com. I currently list them as additional resources for my students, but I could see using them exclusively in a class.

I have spent the past two years implementing Modeling Physics in my high school classes. It is based on a solid few decades of ongoing physics education research and has been recognized as one of the most effective physics education methods yet developed. The Department of Education agrees.
What it does not include in any significant amount is lecture. And while I'm not a top level expert in modeling physics just yet, I do my best to keep students engaged in the learning cycle as we go through each physics phenomenon to model, from constant velocity motion through forces and energy and beyond.
