Why is a wheelbarrow load of soil or firewood easier to move around than a wagon load?

It's not spring yet, but I recently had a discussion about this subject, which led to some minor research. Like simple devices like the nutcracker, the human arm, scales, a see-saw, the crowbar, ratchet wrench, scissors, catapults, and the fishing rod, a wheelbarrow is a lever. In fact, a Type 2 Lever.

By a miracle of physics, levers magnify the force that can be applied with a given amount of effort. Archimedes was the first to attempt to describe the principles of levers. As the physics limerick goes:

One morning while eating my Wheaties,
I felt the earth move 'neath my feeties.
The cause for alarm
Was a long lever-arm,
At the end of which grinned Archimedes.

So, using by using your body to apply effort, with lever action, you are magically carrying a fair amount of the load of the wheelbarrow. A wagon offers no such advantage. (I will spare you the math with the factors of friction, torque, vectors, etc. that make a seemingly simple tool like a wheelbarrow surprising challenging to define.)

(As an aside, let me ask whether they let kids nowadays graduate from high school and college without taking calculus, physics and statistics? If so, wrong, wrong, wrong. This stuff is BASIC. An educated person knows Latin or Greek, calculus, basic physics, basic chemistry, and statistics. Or they are only half-educated about reality and seriously handicapped in the tools for understanding this world. Saddest thing: you forget it all, over time, but, like bike-riding, it's in there somewhere, and the brain can re-connect with it with the right "links".)

I am partial to two-wheelers. The increase in friction, I feel, is compensated by the lack of wobble (torque). Photo is the Ultimate Wheelbarrow from Cariola.

Glitter and be Gay, from Candide:

The varieties of Heuchera available these days is remarkable.

Thanks to the magic of genetic engineering, these excellent shade plants, grown best in masses as ground-cover (more for their foliage than for their delicate and modest Spring flowers) now come in every imaginable leaf color.

This site has a number of new varieties. Their "Ginger Ale" is cool.

From our mens' Bible study this morning:

If you had one chance to learn the time and mode of your death, would you say yes or no?

A quote from Allan Gurganus' The Lessons of Likeness: being a true history of Thomas Eakin's Portrait of Walt Whitman:

This oil portrait braids the sagas of two self-described toughs: Walt Whitman very much of Brooklyn-New York and Thomas Eakins, a definite Philadelphian. A couple of American pioneers, the John Muir of literature and at least the Kit Carson of 19th century Main Line aesthetics! Of all the portraits depicting our nation’s outsized Gandolphian wizards, I have fixed on this one for the simplest reason: I love the work of both sitter and artist. Their efforts go on changing and enlarging my own efforts. Respect and awe leading to love—surely that’s at least the beginning of an understanding?

Don't tax you, don't tax me: tax the fellow behind the tree.

Who was always saying that, dear readers?

As if to reinforce the post below, today AOL news creates a Depression-era scare story: People selling their belongings to survive. You would think things were terrible because of tag sales. Meanwhile, economic data say no recession yet, but if people are fearful enough, the media will provoke one in time for the election.

So what's the big issue, other than everybody's normal everyday challenge to build the life that suits their desires and their conscience?

If economists only do things that make economic sense, then Captain Capitalism lists a few things they surely do not do.

I would add one more: they would never run a blog like Maggie's Farm.

It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.

A propos the piece on reading in college which we linked this morning, Insty came across another bit in The Chronicle titled America's most over-rated product: the Bachelor's Degree.

Today, amazingly, a majority of the students whom colleges admit are grossly underprepared. Only 23 percent of the 1.3 million high-school graduates of 2007 who took the ACT examination were ready for college-level work in the core subjects of English, math, reading, and science.

Perhaps more surprising, even those high-school students who are fully qualified to attend college are increasingly unlikely to derive enough benefit to justify the often six-figure cost and four to six years (or more) it takes to graduate. Research suggests that more than 40 percent of freshmen at four-year institutions do not graduate in six years. Colleges trumpet the statistic that, over their lifetimes, college graduates earn more than nongraduates, but that's terribly misleading. You could lock the collegebound in a closet for four years, and they'd still go on to earn more than the pool of non-collegebound — they're brighter, more motivated, and have better family connections.

Read the whole thing. It makes sense that the degree must be degraded as more people seek it, and as more colleges seek students to fill their buildings.

I am reading the new biography of Albert Einstein. Few college students today could pass the entry exams that he took, which included calculus, literature, French, physics and chemistry. He failed them the first time, in part because his French exam was judged to be weak. (No, he never flunked math.) He spent a year after high school studying to take them a second time.

My point is that "education" or a liberal arts degree was never intended to be a "consumer product." Now it is viewed that way, in the US. And that is a big part of the problem in how we think of education today, because it is not something that can be bought for any price: it is something that can only be taken by those who really want it.

As Englishman notes, the tropical troposphere should be the most sensitive indicator of global warming. It just isn't happening. Full discussion and details at Climate Audit.

There is another class of colored people who make a business of keeping the troubles, the wrongs, and the hardships of the Negro race before the public. Having learned that they are able to make a living out of their troubles, they have grown into the settled habit of advertising their wrongs -- partly because they want sympathy and partly because it pays. Some of these people do not want the Negro to lose his grievances, because they do do not want to lose their jobs.

Springtime, and amore is in the air. (h/t, Theo)

Quoted from VDH:

As I said before, between Wright's racism and hatred, and Obama's contextualization of what he has said, we have so lowered the bar that the next racist (and he won't necessarily be black) who evokes hatred of other races and then offers a mish-mash pop theory of genetic differences will have plenty of "context" to ward off public fury.

Orwellian times.

I think so, and Climate Skeptic agrees:

Observe today how little of the discussion is about anything other than climate.  There are still many environmental issues in the world that can be improved by the application of man's effort and technology -- unfortunately, climate is the least of these but the issue getting the most attention.  Consider how the global warming panic has sucked the oxygen out of the environmental movement.  Ten years from now, I predict that true environmentalists will be looking back on the hysteria over trace amounts of CO2 in the atmosphere as a huge setback for real environmental progress.

As readers know, we are old-time Conservationists here. We believe in National Parks, State Parks, nature preserves, farmland protection, habitat protection, species protection, zoning, "open space", clean rivers and waters, unpolluted air, and we do not approve of the government subsidizing real estate developers and urban sprawl by building highways to nowhere.

The Audubon Society came into being to protect Egrets. The photo above of an American Egret in CT, with his breeding plumage (sent in by a reader last week), shows the reason. At the turn of the century, those breeding-season plumes were all the rage for decorating lady's hats. Thus our egrets - the American and the Snowy in particular - were hunted almost to extinction. That is called "unsustainable use."

The same applied to the market-gunning and netting of waterfowl - and the Passenger Pigeon. Of necessity, we now have hunting laws, hunting seasons, wildlife refuges, and protected species.

Thus we are not Libertarian when it comes to land-use and unsustainable and irreversible exploitation of wildlife or wildlife habitat. The Conservation Movement of John Muir and Teddy Roosevelt had to become politicized, because laws were required in the presence of competing interests: witness, nowadays, the political conflicts in MA and in Europe around the efforts to enforce sustainable fish harvests.

We simply try to be rational about it all. For example, we have no problem with oil drilling in ANWAR or off the Florida coast (as the Cubans and Chinese are doing). We have no problem with responsible logging, which effectively mimics the effects of natural wildfire on forest succession. We love to hunt and fish, and do so responsibly and sportingly. We think the earth probably has more than enough people on it. We favor nuclear power for reasons of energy independence and because it's the closest thing to a free lunch after compound interest. We feel that biofuels are a lousy idea for many reasons.

At the risk of sounding corny, we believe in good stewardship of our inheritance.

What's irrational? The Green Movement is irrational. Most of it represents feel-good ideas that are hooey: symbolic hooey that is meant to make people feel virtuous while accomplishing nothing. Witness the lightbulb craze, "organic" vegetables, "recycling" plastic bottles (totally energy-inefficient), or hybrid cars (which do nothing "for the planet" but which are great on gas mileage). It's empty vanity and fashion, and nothing more (for an example, see this foolish agonizing piece by Michael Pollan, who has caught a bad case of the vain and guilt-ridden sanctimony of the "I can make a difference" disorder).

Pure organic pixie dust for the latte liberals.

The CO2 obsession is similarly irrational, and, deep down, everybody must know it. It is irrational because it is futile, regardless of whether there is any current warming, and regardless of whether there is any man-made warming. (We suspect that it is long-term cooling.) As Steyn said yesterday at NRO:

Whether or not there’s very slight global cooling or very slight global warming, there’s no need for a “war” on either, no rationale for loosing a plague of eco-locusts on the food supply. So why be surprised that totalitarian solutions to mythical problems wind up causing real devastation? As for Time’s tree, by all means put it up: It helps block out the view of starving peasants on the far horizon.

If anybody thinks the Chinese, the Russians, and, eventually, Africa, intends to stop building fossil fuel power plants, they are dreaming. If anybody thinks wind power will ever be more than a drop in the bucket - even if subsidized as it is - is dreaming. And those who want (more) "carbon taxes" just want another cover, another excuse, to take more of our money. They can have more "carbon tax" if they reduce my income tax to compensate.

Everybody wants more power, and as cheap as possible, because power is the wonderful stuff that makes our modern civilized, efficient and lazy lives possible. The rapidly-developing world understandably wants more of it.  Somebody will need to pry my Stihl saw - and my computer - from my cold dead hands.

So, to meander back to my main topic, I agree with Coyote that the CO2 frenzy and the other trendy Green frenzies have "drained the oxygen" from a Conservation movement which has many other compelling areas in which it can be, and should be, effective. And, yes, I do believe that many of those Greenies are motivated by a Socialist agenda using "Gaia" as a front. I will believe their sincerity when they quit driving and flying. However, their socialist-totalitarian streak, plus their wackiness and scolding, have damaged rational conservation goals via guilt by association.

On the other hand, I do favor the use of local, state and federal powers (and especially some non-profits which do the same things free from political considerations) for the conservation goals which are important to me, which I believe to be rational, and which I like to believe contain no ideological agenda but which certainly contain a moral and practical agenda: we do not wish to hand down a planet covered with asphalt and oceans without Codfish.

Some things - maybe just a very few precious things - should be more important than freedom and free markets, but that's where the political debates begin, isn't it? That is the line of scrimmage.

On the "values" scale, we rank individual freedom at the top of the list, but, like everybody, we also have competing values, morals, and interests.

Bush at the Correspondent's Dinner last night:

"Hillary Clinton couldn't get in because of sniper fire, and Senator Obama's at church."

Talked with an older gent this weekend who had been a Skipper of an LSM in the Pacific during the war. He correctly guessed that I could not describe an LSM. Landing ship, medium. Odd-looking craft.

We built over 500 of them. Designed for island-hopping, smaller and quicker than LSTs, carrying just 3-4 tanks and crews. He said he did a lot of ferrying, and they were too small potatoes for kamikazes or subs to bother with. He said they put plenty of 40 mm in the air, but thinks that they never hit anything.

For landing, they threw out a stern anchor, then headed for the beach. As the tanks off-loaded, you could maybe float off. When you loaded tanks on, you needed the stern anchor winch and hoped for the best.  You were not supposed to get stuck.
