Higher Education’s Next Wave

I whole heartedly agree with a move to a system of incremental learning and a focus on mastery and relevance as discussed in this article. I even feel it should filter down into the post elementary, even elementary school, so that the line between home, public and private schooling becomes blurred.

It’s interesting that the Internet is leading to the disintermediation of an ‘industry’ once more, ‘getting rid of the middlemen’ who add minimal value while sucking $ out of the revenue stream (i.e. the now obscene number of administrators in education.)

Incremental learning would focus people more on life long learning instead of the ‘boost and glide’ model we have today, I know that I am a far better student today than I was as an undergrad and know far more about what I should be learning and could use. There are many people in mid career who if the education were available and cheap could potentially make career changes and add great value to society/industry if their practical knowledge were supplemented with more analytical/academic background.

Many (guys in particular) are still too immature at 18 – 22 to know what they want to do with their lives and have a hard time sitting through “bullshit” pre requisite courses that would probably do them much more good a few years (or a few months) down the road when they understand the value. It’s not like this is the last bulwark of good English, that line fell long ago.

One downside to this in some people’s minds might be the loss of ‘life insertion support’ that university provides. This has been a accepted (not always gracefully or willingly) part of a university’s job from their origins in the middle ages.

On the upside, does it provide the opportunity to look towards a trainee and apprenticeship model of life insertion? Our current over protective society has progressively withdrawn our offspring from the real world over the past 100 some years with the most radical shifts in the early and late decades of that period. This is making it harder and harder to ‘lifestream’ them.

The child labor laws today are blanket and draconian because that’s the habit from early on when otherwise enforcement was all but impossible. Also recognize that the laws were a form of price support for adults by getting cheap labor off the market. Today monitoring is much easier and safety really is important, why not let the kids start working at earlier ages, especially if they can structure education around their work schedule, and learn life lessons much earlier and hopefully more gradually. If education becomes a life long goal, like good health, exercise, good citizenship, etc, then the first 12 years of your public life could perhaps be much more fulfilling and broad as well.

What I have sketched here is a bit of a forward into the past scenario, this would be more like it was in the past before vast bureaucracies and their one size fits all models took over from the chaotic getting along going along organization of the nineteenth and early twentieth century.

We can perhaps see what is happening as the collapse of the bureaucratic model of organization as ‘the Internet’ and reasonably capable software eliminate the need for a one size fits all models which have tried to ‘adapt’ to an un-regimented populace by the ‘cushioning’ of thousands of special assistants, ombudsmen and administrators of this that and the other.

Sundays always get me down…

Trying to keep up with a busy real job schedule and my desire to get Exotic Contraband ready for the first book to be published on Smashwords so blogging has not been prolific, will at least be home this week, hope to get a few meaty posts done. 

Used to be that Sunday was the day before Monday and I dreaded school…until I got over that and actually started to like it.  Then it was the day before Monday and I had to face the fact that I was just a cog in the gears of my job.  Then I was a manager and I would have to face the folks who worked for me and keep up expectations.  Next I was working for myself and Monday meant having to figure out how I was going to keep it up after the near term mana gave out.  Then I was working for a small company and it meant another week of 12 to 14 hour days, and commutes that really sucked, though I enjoyed what I was doing.  Still the case but now its the realization that I didn’t get to most of the things I’d intended to do over the weekend and the week is going to be clogged… 

But then isn’t that the human condition, never really satisfied, isn’t that what keeps us moving forward?

Sorry edited, used the quick blog button and it made the central paragraph a differen color and unreadable on my blog….had to get into the HTML, I find that WP is a way to learn some HTML…again.

So I need to up my game

Work absorbed my time this week, one of those weeks where every hour was tagged and I almost forgot several calls even though my electronic adjuncts tried to keep me on path.  I work with some really great people who I enjoy spending time discussing problems of society, America, industry and the world, we almost always solve most of the problems by the end of the meal. 

But after solving the world’s problems verbally I just didn’t feel like blogging…and with the iPad and the WP app there is really no excuse for that.  So I need to make another dedication to getting at least something, even its just “Mehe” or “Have some eye candy, now don’t bother me conscience’

Speaking of eye candy the series of solar eruptions have produced their usual stunning skyworks and since the cycle is 11 years, this is the first solar maximum in the age of digital photography so there are fabulous, fantastical pictures all over the web.

APOD Aurora Image

Such as this one, todays APOD eyecandy.

APOD Aurora Image

Or this one from the Jan 24th APOD.

Those were from two solar flares, the first a 3 the second a 2, there has been a near max one as well (above a 5 on the scale which is a log, scale so more than a thousand times stronger than the one that produced the image above.) Here is a bit more information.  You’ll notice that it’s from Kent (England) which is because the English, and even more the Scots see a lot of this sort of thing, the British Isles are surprisingly far north (Hudson Bay Canada sort of North.) The Aurora is a polar effect due to the Earths powerful magnetic field (which prevents this sort of thing from sterilizing the planet) the magnetic field lines plunge into the body of the world north and south, allowing the energetic particles to interact with our atmosphere, creating plasmas, immense natural neon signs.

BRAVO: Red Tails, Everyone should see It!!!

Red Tails Broadsheet

Saw this movie with my son today (Sunday 22nd Jan).  This is like Saving Private Ryan a watershed war movie.  It is fabulous to watch, the characters are realistic and well played so you care, the story telling is deft, there is no complexity her but that’s not the point.  It is an uplifting story of brave men (all types of bravery) trying to do the best they can and winning on more than one level.    

I will warn you that I do not go to movies to learn history, neither do I go to them to learn philosophy of life lessons, I go to be entertained.  And most movie critics these days appear to be operating in a different plane and writing for each other not the folks in the real world. 

The biggest problem I have had with many war movies up until recent time is technical.  All the compromises that had to be made to make any large scale war movie and my inability to look past ‘minor’ issues like US M48’s used in The Battle of the Bulge to represent German Tigers/Panthers. 

Red Tails shows that modern technology and good film making are beyond this, the setting is viscerally real throughout, providing a rich background canvas that the people and the action can play out in. Absolutely fabulous aircraft scenes throughout.  When the only thing I could gripe about is that sometimes they made some of the ground sets look too old and worn I should just shut up…. and the mud and basic layout etc were again exquisitely done. 

The men (and it really is all about men the only female character though sweetly played is only a set piece) are well played, it might have been biased for modern tastes but they came off as real, the relatively clean cut, slightly less demon ridden people of a simpler day men who were playing their part in two wars.  One with bullets and one with hearts and minds. 

This movie was rated very highly by the public and moderately low by the critics.  The explanation I have for that is that the Critics cannot stand a movie that puts the bigotry of the time in the proper context.  It was so obviously a constant drain on the men but it was the background to their lives, the constant slights many unconscious rather than direct attacks.  I am very sure many critics wanted a movie that wallowed in the bigotry and hatred a bleak look at the dark hearts of men (we don’t need that, know all about it.)    Instead what is here is a simply fabulous war movie about men I grew to care about that made its point about the utter stupidity of bigotry by positive rather than negative example.

Bravo Lucasfilm, George Lucas, Industrial Light & Magic, and of course the writers, director and actors.

A few chemicals and a microwave and see what you get

Zapping raw materials in a microwave oven and drying the resulting solution produces a black powder (top) made of hexagonal bismuth telluride nanoplates (bottom).

High-efficiency thermoelectric materials could lead to new types of cooling systems, and new ways to scavenge waste heat for electricity. Researchers at Rensselaer Polytechnic Institute in Troy, New York, have now developed an easy, inexpensive process to make such materials.

The materials made by the RPI team already perform as well as those on the market, and the new process, which involves zapping chemicals in a microwave oven, offers room for improvement. “We haven’t even optimized the process yet,” says Ganpati Ramanath, a materials science and engineering professor at RPI. “We’re confident that we can increase the efficiency further.”

What caught my eye here is that the material is a form of nano particulate, its produced in an evidently very simple process and it has a very high efficiency.  This type of technology as the article notes could have a great number of applications.  In a car one could conceive of replacing the mechanically driven alternator with something like this or supplementing it, this would essentially be using waste heat to provide electricity and would increase gas mileage.  There are many other places where heat scavenging would make sense and have an impact if the materials and system were cheap enough.  This goes back to a fundamental issue, energy efficiency costs money and if the cost of burning a tiny fraction more fuel over the life of the system (which can add up to biggish $) is less than the energy scavenging equipment then the equipment will not be installed unless the added cost is passed on to someone. 

 

Algae to the rescue

Green tea: Joule Energy's SolarConverter turns carbon dioxide and sunlight into ethanol fuel at a pilot plant in Leander, Texas.

 Technology Review| Photosynthesis Fuel Company Gets a Large Investment:  Joule Unlimited will build a production plant for turning sunlight and CO2 into liquid fuels.

The company is combining many technologies to move to direct creation of biofuel precursor liquids.  The algae is similar to that others are experimenting with but excrete the molecules into the water instead of retaining inside the cells.  This way the harvesting ‘only’ entails fractionating the liquid from the flow.  The bioreactors are essentially double panel windows with the algae filled liquid flowing inside.  The water gets CO2 from a power plant which scrubs it out of the plant effluents and one guesses that in cooler climates the water could be warmed in the cooling cycle of the same power plant so the system could operate year round.

The company calculates that their system can produce a great deal more, more easily refined biofuel precursor liquids than the alternates. Which mostly involve growing various kinds of plants and then converting them to biofuels in either chemical or bio reactors.

Aerovironment micro UAV

20120116-223425.jpg

AeroVironment’s Hummingbird NAV shown in the palm of a hand to give it scale. The company has been able to fly the NAV (nano air vehicle) indoors and outside, including flying it through doors and down corridors into a workshop and office environment.

From the SAE aeronautics eNote. Not new news but best picture and ‘technical’ description yet.

AeroVironment has captured the imagination of a worldwide audience with news of a major extension of its activities into nano air vehicles (NAVs). Ever since human beings first discovered the basic principles of lift and the importance of wing shapes, the necessary muscle power and control movements of birds defeated all attempts to emulate the mechanical process of using wing flapping to beat gravity. The hummingbird’s amazing ability to conduct a perfectly stable hover has long fascinated students of aerodynamics, especially when slow-motion film footage displays the complexity and perfection of its ultrahigh-speed wing flapping movements.

Elgin First Draft is Done and Posted

Cover

The wait is over, at least for the unedited version.  So when the 24th of Nov hit it was 58K words.  It is now 122K and you may not believe this but it’s the shortest book and by far the shortest draft I’ve ever managed.  I think it works, I hope you like Elgin and his world.  It’s probably not everyone’s cup of tea, it rises through a series of peaks to a crescendo then slips into the end.  

Download, enjoy, especially if you’ve downloaded, read and enjoyed the first parts.

And remember that the finished Moon Dreams and Under Siege are available.
