It’s Any Day and Robert Samuelson Is Vile

Robert SamuelsonRobert Samuelson is a truly vile person. He uses his prominent perch at The Washington Post to argue week after week that all of our problems come from the fact that we treat our elderly too well. He thinks Social Security pays too much, even though it pays out what it takes in and it is not nearly as generous as similar programs in other advanced economies. And then he complains about all the money we spend on Medicare, but isn’t at all concerned that the cost is so high because we pay twice as much for our healthcare as people in other advanced economies where the medical care is better. He just wants to harm the poorer people in our society and assure more and more money for the already rich. Like I said: he’s a vile guy.

On Christmas eve, he sunk to new lows, Repairing the Middle Class in 2015. The title itself is funny. As if Samuelson is in the least bit interested in helping the middle class. But the article itself is just one distortion after another. He claims that the American system is not rigged against the middle class but rather for the middle class. “That’s a natural result for a democracy in which politicians compete more for votes than for dollars.” No serious person could look out on the vast American political system and conclude that the votes really matter. A tiny investment of $8 million by Monsanto caused a hugely popular GMO food labeling bill in California to go down to a resounding defeat.

But when it comes to all that money that the middle class is getting from the government, Samuelson points to — Surprise! — Social Security and Medicare. Keven Drum calls him on this issue, The Middle Class Needs More Income. Faith Will Follow:

When we speak of the “middle class,” we’re nearly always talking about the working-age middle class. Samuelson surely knows this. But the only programs he calls out by name are specifically directed at the elderly and the working poor. Barely a single dollar of those programs goes to middle-class workers.

But Samuelson doesn’t leave it there. He goes on to complain that most of the taxes fall on the rich. Well I wonder why that might be! Median incomes have been stagnant for almost four decades. But he is further disingenuous by looking only at the federal government where taxes are most fair. As I showed last week when discussing the supposed Texas Miracle, state taxes are usually ridiculously regressive. But Samuelson doesn’t want to talk about that, because he isn’t interested in what the truth is about life for the poorer classes in the United States. He’s interested in pushing the interests of the oligarchs.

But if that weren’t bad enough, he then goes on to blame the financial crisis of bursting the house bubble on those evil poor people getting loans they couldn’t afford. He noted, “There is much evidence for [the cause of the financial crisis], but it ignores the deeper cause: an intellectual, political and social climate that legitimized lax lending policies in the name of promoting middle-class well-being.” To begin with, those lax lending policies were not created to help the middle-class. They were created to help bankers make a lot of money. But his narrative is just outrageous. Oh, those poor bankers being pushed around by the intellectual, political, and social climate! Funny how when people are screaming for jobs, the business community is sitting on piles of cash, despite the intellectual, political, and social climate.

Samuelson ends his article by noting that the challenges for the middle class are only partly economic. It is also psychological. It seems we can’t really control the economic environment, but we can control ourselves. So let’s not do anything about the economy and let’s complain that the middle class just kind of sucks. Dean Baker called this for the nonsense that it is, Robert Samuelson Thinks That Because He Is Confused About the Economy, Everyone Else Is Also:

In fact the government has structured the market over the last three decades in ways that cause most income to flow upward. For example its trade deals have been focused on putting less educated workers in direct competition with the lowest paid workers in the world. This has the predicted and actual effect of driving down their wages. At the same time, highly paid professionals, like doctors and lawyers, are largely protected from international competition. The government has also had longer and stronger patent protection, causing middle class people and the government to pay hundreds of billions more for prescription drugs than would be the case in a free market. The benefits from these forms of protectionism disproportionately go to the wealthy.

The government also has adopted more anti-union policies in the last three decades, substantially reducing the ability of workers to organize effective unions. It also gives huge subsidies to the high six and seven figure salaries of top officials at non-profits like the Gates Foundation.

And the government gives free too big to fail insurance and special low tax status to the financial industry…

It’s also interesting that the government has done nothing to keep the minimum wage up with the rate of inflation — to say nothing of the rate of productivity growth. The government has done everything it could get away with to screw the poorer classes and lavish the rich with every possible benefit. But that’s what Robert Samuelson thinks it ought to do. I just wish he were more honest about it.

Texas Might Take Medicaid Expansion

Greg AbbottMichael Hiltzik offered up some potentially good news at the end of this year, Is Texas, the Biggest Domino, About to Topple on Medicaid Expansion? It seems that not all right wing freaks are created equal. With Rick Perry and his Super Glasses leaving office to pursue truth, justice and the American way, governor-elect Greg Abbot has indicated that he might be open to taking the Medicaid expansion in the form that Arkansas and Utah have pioneered. In it, instead of the working poor getting added to Medicaid, they are given money to buy insurance on the exchanges. It ain’t perfect, but it is a distinct improvement on the way things are.

It’s kind of the perfect way for Republicans to dip their toes into Obamacare. After all, they are already part of it. The citizens of Texas are already required to have health insurance. And they are already paying higher taxes for the new law. So they are getting everything bad from the law and relatively little good from it. They might as well get some of that money back that they are sending away. The way the law was designed, blue states (because they are generally richer) were subsidizing red states. But because Republicans have been so spiteful about Obamacare, it’s worked out that red states have been subsidizing blue states. This is not a state of affairs that can go on for long.

This kind of “block grant” approach to the Medicaid expansion is something that Republicans have long claimed to like. And this kind of deal is a great face saving maneuver that allows the Republicans to claim both that they made the evil president bend to their will and that they don’t just hate the working poor. (Even though they clearly do.) Now we will have to see if Texas goes along with this. It is still likely that the Texas legislature will be unable to get past their mean girl spite and do what is best. But this is good news regardless.

Hiltzik runs the numbers in his article and they are overwhelming. Texas has the highest level of uninsured residents with over 22%, when the average is around 13%. And with bad economic times coming to Texas, it will only get worse. A 2013 report found that by not taking the Medicaid expansion, the state was set to lose almost $8 billion and have extra costs of almost $400 million. That was for a two year period. What’s more, hospitals are getting hit hard. Each year, they do $17 billion in uncompensated work. The Medicaid expansion would take a big chunk out of that.

I spend a lot of time complaining that the Democratic Party is too much the party of big business. But what’s remarkable is that the business community is so wedded to the Republican Party when the party doesn’t look out for its interests at all. Its general incompetence hurts business growth but on the individual level, it doesn’t do anything for business except for its trademark crony capitalism.

But we have a perfect storm here in Texas. It is losing a huge amount of money. The hospitals are keen to see the extra money coming in. The state is looking at bad times ahead. And it has a perfect face saving excuse for signing up for the program now. Given the absolute joke that the Republican Party is — especially in Texas — we can’t say what will happen. But this is hopeful news. And if Texas accepts the Medicaid expansion, many other states are sure to follow.

Bo Diddley

Bo DiddleyOn this day in 1928, the rock legend Bo Diddley was born. It’s a little strange though. He is literally a household word. But people don’t so much know his music. This is partly due to the fact that he never had a song that charted high on regular pop radio. His biggest hit was the confusingly titled “Bo Diddley” — which made it to number one on the R&B charts but didn’t make it on the pop charts at all.

I know that when I was younger, I was confused as to whether Bo Diddley was an actual person or not. Of course, he isn’t really. That’s just the stage name of Ellas Otha Bates. But even at that time he was an important artist. And he was hugely influential with musicians I would go on to love like The Velvet Underground.

What most defines his work is his use of really compelling, driving rhythms. You hear this on his first and biggest hit, “Bo Diddley” where there isn’t really much more than the rhythm. Additionally, the vocal to it has the sound of a field song. It’s all very simple but fascinating:

Happy birthday Bo Diddley!

Cosmos and the Lack of Politics

CosmosBecause my sister knows me well, she bought me the new Cosmos on DVD for Christmas. I had seen much of it before, but I’m glad to have it. For one thing, it has allowed me to share it with my father who likes such things. But I have to admit that it bothers for a few reasons. The most minor of these is simply that I’m an old curmudgeon. I know far too much science and I bristle at every statement that isn’t quite right. I found that to be especially true in the fifth episode because it dealt with relativity and that’s a subject that people seem to be unable to discuss with any degree of clarity. And then there was some mixing up of special relativity and general relativity and I was fit to be tied. But that really is minor.

What most bothers me about it is the politics of it. The first several episode were filled with scientific hubris. This is an issue that causes me no end of problems in my relationships with fellow atheists. It’s kind of weird. The scientific process is an amazingly powerful thing that I greatly admire. But there is a tendency among people to think that it is the end all of knowledge. And it just isn’t. It is the ultimate in the old joke about the drunk guy looking for his keys under the lamp even though he dropped the keys in a different location, “The light is better here!” Science is a great way to answer certain kinds of questions. But there are questions that science just can’t parse. So those questions are just avoided or defined as non-questions.

So it is great that we have science around to pound away at our knowledge. But it is generally not the case that what we want for is a scientific approach to solving problems. In the 13th century, for example, the Dominican Theodoric of Freiberg managed to figure out the rainbow. The biggest problem is not how we will go about answering questions. The biggest problem is that it doesn’t even occur to us that questions ought to be answered. To me, the best example of this today is found in the field of economics. It seems like a science. The same process is used with data and models and all that. But fundamental questions are simply not acceptable. Where in the world of mainstream economics are there people asking how property — a commonly held resource — can be privately owned? That’s just an illegitimate question. The best we get is an analysis of income inequality, which the profession has denied to generations and now shoves aside with various arguments — most notably with the idea that inequality is great because we have iPhones.

And this gets to my primary problem with Cosmos. The takeaway from the original series really wasn’t scientific. Rather, it was that science is a powerful means of understanding the universe and so it must be used to counter bad ideas in the lives of humans. In particular, Carl Sagan was interested in nuclear arms. But what is the new series interested in? Perhaps it is a sign of the times that the big fight now is just against ignorant theists who want to teach Creationism in science classes. But I think it is a major mistake to even step down to that level. So what great policy is Tyson willing to tackle? Nothing really. He doesn’t say much more about global warming than Carl Sagan said three and half decades earlier.

Add to this the fact that the producers of the series made the terrible decision to put the show on commercial television. The original series provided a whole hour to deal with a subject. But here, the narrative is interrupted every ten minutes for everyone to be reminded what really matters: commerce. And that’s what I mean about the questions we don’t ask. Is science a common good that should be shared with all of humanity? Or is it just a way of delivering eyeballs for commercials about soft drinks and erectile dysfunction medications? I think the former, but our society clearly thinks the latter. Sadly, the new Cosmos does not have an opinion on such matters. That means that the producers of the series are doing just what those who ran the Library of Alexandria did: nothing. And Carl Sagan pointed out the problem with this kind of disinterested science in the original Cosmos.

Useless Mainstream Media

Chuck ToddCharlie Pierce made an interesting comparison over at his place at Esquire, Life And Cheerios Imitate The Newsroom. He started by noting the ridiculousness of Chuck Todd claiming that he has to allow Republicans (“politicians”) to lie on Meet the Press, because if he didn’t, they wouldn’t come on the show. It was a remarkable moment of honesty, although Todd does seem to think it is about “balance.”

I think it is typical of what I call “fake power” — the kind of power you only have as long as you don’t use it. The best recent example of this has been Speaker of the House John Boehner who has enormous power, but if he ever used that power to do what was right rather than just to do what his caucus wanted, he would find that he was out of a job. Similarly, Chuck Todd has the power to ask the “hard questions” only so long as he absolutely never asks the hard questions.

It reminds me of something else. You could watch the nightly news on ABC, NBC, and CBS. And you would never see anything different. It is a remarkable example of self-censorship. Either that or it just so happens that the major news outlets manage to get right to the heart of what is going on in the world. Of course, we know that isn’t the case. You can go back over the decades and see what the news sources were reporting in their amazing unanimity and see what was really going on. It’s just follow the leader.

Meanwhile, all the time I was growing up, I was told that the Soviet Union didn’t have a free press. Well, true enough. But that didn’t speak poorly of them so much as it speaks poorly of us for thinking that we do have a free press. It’s like what Noam Chomsky said in The Common Good, “The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum — even encourage the more critical and dissident views. That gives people the sense that there’s free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.”

So good old Chuck Todd is there to play the part of a free journalist. And indeed, he isn’t being told what to say and not to say by the government. Oh no! He’s being told what to say and not to say by the “free” market! And that is better because… I’m not sure. No one has ever answered it because no one seems to even be aware that it is a question to be answered.

Pierce focused primarily on Reince Priebus’ recent hissyfit about not allowing any Republicans to come on MSNBC, after someone at the network had tweeted out, “Maybe the rightwing will hate it, but everyone else will go awww: the adorable new #Cheerios ad w/ biracial family.” MSNBC folded like a cheap ironing board, of course. And Pierce notes that if a Democrat had made a similar demand, he would have laughed out of polite company. But there is a difference I’m afraid: Democrats aren’t bigots. If half the electorate that votes Republican weren’t compelled to do so by their bigotry, Priebus wouldn’t have felt the need to demand an apology.

I don’t think there is an other side to this situation. Democrats — despite their many failings — actually believe in what they claim to believe in. It isn’t the case that half of the Democratic vote comes from closet communists. And even that would be more acceptable than the racist base of the Republican Party. So of course if the Democrats started acting like the Republicans, people would scoff. It’s pretty much impossible to imagine a comment that would cut the party so deeply while also being true.

What’s wrong with our media system is that people like Chuck Todd don’t start interviews with Reince Priebus with questions like, “What is the Republican Party going to do when all its racist voters die off? Does the party have a plan to create new racist voters?” But that won’t happen. If it did, the Republicans wouldn’t come on Meet the Press, and people like Chuck Todd would have to do actual journalism. And I don’t think there are many people in the mainstream press that still know how that’s done.

Religious Offense and The Life of Brian

Life of BrianAs I’ve been on a Monty Python kick recently, I’ve revisted Life of Brian. It is the best thing that the group ever did — in terms of comedy, theme, and simple move making. It is a great film. But I don’t think we need to discuss that. Most people I know think that Life of Brian is the pinnacle of their work. What I find more interesting is the fact that the film was controversial. But my memory about it was vague. And I really wondered whether there was much of that. I know that there are silly people who get offended by any discussion of Jesus that isn’t reverential. But were they really upset about Brian? It is hard to believe.

The main reason that it is hard to believe is that the film is reverential toward Jesus. If you ask me, it tries rather too hard in this regard. There are only three instances where Jesus plays a role at all. The first is after the wise men mistake Brian for the Jewish savior. When we finally do see the baby Jesus, the whole scene is lit with halos of Mary and Joseph. The second time we see Jesus is at the Sermon on the Mount where he is portrayed with great seriousness by the fine Kenneth Colley, surround by hundreds of followers. And the only other time I recall him mentioned is when the ex-leper discusses how Jesus cured him and deprived him of his livelihood as a beggar. In all these cases, Jesus is presented as he is in the Bible. Brian is just this regular guy who lives at the same time.

But I think I know why the Christians got upset about the film. It isn’t the portrayal of Jesus that they have a problem with. It is that the film makes fun of fanaticism. It has no opinion about being fanatical about a good cause. But most people are just keen on following anything at all. And that is key, I think. Most Christians are only followers of Jesus for one reason: their parents were. So Life of Brian brings up a very uncomfortable question for Christians, “Does your belief make any more sense than the Heaven’s Gate cult?” To me it is very clear that the Heaven’s Gate cult makes a lot more sense because at least those in it, chose it rather than just accepting what they heard as children.

What’s remarkable, however, is that it wasn’t just your garden variety cultural Christian who had a problem with the film. In the follow interview from the time on Friday Night, Saturday Morning, Malcolm Muggeridge and Anglican Bishop Mervyn Stockwood debate John Cleese and Michael Palin. And they both make the argument that Brian is Jesus. I suppose that that is about the only argument that you can make. The truth isn’t going to fly. They just can’t say, “The film makes us look stupid.” But it does show that even those we think of as serious Christians really aren’t.

What’s perhaps most interesting in this interview is how angry Michael Palin is during this. By all accounts, Palin is a the nicest guy you would ever meet. But here, he really doesn’t seem to like the way that his work has been misinterpreted. Still, he maintains his composure. It speaks rather poorly of Christianity that Stockwood and most especially Muggeridge go out of their way to be offensive about the film. Muggeridge refers to it numerous times as being “tenth rate” and discusses how the film got easy laughs with four-letter words and nudity. That simply isn’t true. I suspect that his mind was as closed to the film as it was to his religion.

It was curious to be reminded of all this. I do wonder what Christians think they are doing by being so closed minded. But it goes right along with my thinking about religion. The general level of religious thought is so simplistic and useless that a film like Life of Brian really does act as a kind of criticism. And this debate serves the same purpose that the film itself does: the Pythons hold up a mirror to our society. In this case, they didn’t even say very much. The religious figures made the argument themselves. Regardless if one is a Christian or not, he must decide that he doesn’t want to be that kind of Christian. And that is the the main kind of Christian around.

Update (29 December 2014 8:30 pm)

Infidel753 reminded me of this great parody of the debate:

Jon Polito

Jon PolitoToday, the great character actor Jon Polito is 64 years old. I featured him last year for the birthday post, but there really is no one else I feel that I ought to talk about. It isn’t just that I admire his work. It is also that I’m extremely jealous of him. He has the kind of career that every actor ever wanted to have when they started out. Even though he’s still pretty young, he has over 200 entries on IMDb — and that doesn’t include multiple appearances on a single television show. He also has the sweet spot of fame: famous enough for it to be flattering, but not so famous that he can’t have a regular life.

Primarily, I think his is a great actor. There is depth in his performance that you just don’t find in a lot of established actors. I think it is interesting that in his scene with Jeff Bridges in The Big Lebowski, he dominates. And I say that even as I think Bridges is an okay actor. Anyway, someone put together this nice comedy reel of Polito’s work. Check it out:

My favorite role of his is Johnny Caspar in Miller’s Crossing. He’s the heart of the film, because as much of a psychopath as he is, he’s the only one who has a sense of justice and right and wrong. Sadly, his opening speech about ethics is not online. But here is a little bit from the very end of it:

Happy birthday Jon Polito!

A Terrible Ontological Proof

Why Does the World Exist? Jim HoltSuppose there were nothing. Then there would be no laws; for laws, after all, are something. If there were no laws, then everything would be permitted. If everything were permitted, then nothing would be forbidden. So if there were nothing, nothing would be forbidden. Thus nothing is self-forbidding.

Therefore, there must be something. QED

Surprising Offspring of the “Reasonable” Republics

Vanity Fair - David Brooks and David Frum

While looking for images for my last article, I came upon this image from an article in Driftglass, Today in False Equivalence. I’m not so much interested in the article itself, because it doesn’t actually address what they’ve done with this image. It’s a takeoff of one or more of those Demi Moore covers that I guess are supposed to say that the magazine is celebrating the beauty of pregnancy, but somehow always come off as a celebration of pregnancy fetishes. But in this case, the point is clear: supposed reasonable conservatives don’t want to take responsibility for the craziness of the conservative movement.

Actually, I don’t know if they care. Based upon his writing, David Brooks seems a little concerned. He is part of the long line of conservatives who are embarrassed by all the coarse things that other conservatives say. Brooks is careful with his language so that when everything that he believes in crumbles and destroys millions of lives, he can say, “I said it might be a good idea to raise taxes on the poor and eliminate taxes on the rich; I didn’t say it would be a good idea!” So it makes more sense to apply the unwanted pregnancy image to him.

I have a special dislike for David Frum. He’s as much of an ideologue as any Tea Party wacko. The only reason people consider him reasonable is because he thinks that having a bit of gun control mightn’t be the worst thing in the world. He’s also recently okay with same sex marriage. For decades he was against it because he thought it would be bad for “the kids.” But now the data are in and that case can’t be made anymore. Fair enough. But the truth is that his original problem with it was not based on evidence. It was based upon bigotry. When evidence becomes overwhelming, Frum will change his mind. But it is always up to the world to convince him that his bigotry is wrong. In other words: he’s just a right wing wacko who is smart enough to know when his arguments are untenable.

What I think totally sums up David Frum is the popular phrase “axis of evil.” He’s the guy who invented it. And it shows that like all conservatives, he has no actual interest in the truth. In World War II, the axis powers were a coalition. Iraq, Iran, and North Korea were not a coalition. In as much as they had anything to do with each other, it was to fight. But Frum was more than happy to lump them in together because Frum is an evil little man who doesn’t care about the nation or the world. Just like with Cheney and Bush, Frum cares about power.

The image is perfect in that it shows that the smarter people in the conservative movement would prefer to deny that they are responsible for the state of the modern Republican Party. Those Tea Party people that continue to clog up Congress are an embarrassment. But let’s not kid ourselves. They are an embarrassment because they are vulgar. They are an embarrassment because they aren’t tactical about the long-term goals of the conservative movement. They are an embarrassment because they are ignorant and stupid. But they are right in line with the ideology of David Brooks, David Frum, and all the “respectable” conservatives.

Media Sidetrack Nation From the Truth

Freak OutFor Christmas, Paul Krugman wrote, Tidings of Comfort. He felt that people were kind of glum this holiday season. And the reason is that the media have painted a picture of the world that has indeed been very bleak. There was Ebola that was going to kill us all. Then there was Vladimir Putin and ISIS and North Korea who were going to destroy us because, you know, a democracy could never meet the threat of authoritarians except minor things like World War II that are easy enough to forget about. But perhaps you are like Paul Krugman and you’ve noticed that all of these things are imaginary.

I don’t think any of this is unusual. As a nation, we are always freaking out. We don’t have much in terms of cultural cohesion to hang onto. So we manage our lives by moving from crisis to crisis. We are like adrenaline junkies: we get excited and then we calm down. Wash, rinse, repeat — for the rest of our lives. I don’t much care in a certain way. My interest is in the way that such behavior stops us from dealing with real problems. And I think that our hair-trigger concern that we are, for example, all going to die from Ebola explains why we have the highest levels of teen pregnancy, illiteracy, and income inequality among the advanced economies.

It is hard not to think back to another great American who jumped from freak out to freak out: Ronald Reagan. Remember when he told us, “Government is not the solution to our problem; government is the problem”? What exactly did he mean by that? I was never really clear what that one problem was. But I feel certain that what he meant was that individuals and the private sector was the solution to our problem. But it is three and a half decades later and it is more clear than ever that individuals don’t have the power to solve that one great problem (largely because of policies Reagan himself enacted) and that the private sector has become, if anything, a far greater problem than the original one great problem.

I’ve written a few articles this last week about Darrell Issa. And the main thing that I’ve had to say is that Issa has won in all of his fake scandal mongering. It doesn’t matter in the least that nothing came of those scandals — that there was literally nothing untoward going on. What matters is that he was allowed to go to media outlets all over the nation and push the idea that something was amiss. “Where there’s smoke, there’s fire.” So he got people to think exactly the opposite of what was true and what was in their best interests, “The government is bad; the government can’t be trusted; the government is out to get you.” Imagine that you tell someone a hundred times that the White House is targeting its enemies. And then on the 101st time, you say, “Oops! I was wrong; the White House didn’t do anything wrong.” What are they going to remember? Or more to the point: what are they going to remember when the media don’t even cover that 101st statement?

I have little use for wimps on the left that don’t seem to stand for anything other than maybe technocratic competence. I have no use for the demagogues on the right who will do anything to keep themselves in power and enrich their friends. But there is a very special level of hell that I reserve for our media system that allows disinformation to be reported as fact in the name of balance. It can be very hard to get to the truth of any matter. But our media have given up on it. It’s hard, so they just report what the two powerful sides of the debate claim. And usually, the truth is far from both.

Physics, Math, and Life

Hockey PuckYesterday, Will sent me over a curious article, Hockey Puck Math. It’s one of those Yahoo! answers pages. Apparently, someone had some physics homework and they decided just to ask online, “A hockey puck is hit on a frozen lake and starts moving with a speed of 13.7 m/s. Five seconds later, its speed is 6.80 m/s. What is its average acceleration? What is the average value of the coefficient of kinetic friction between puck and ice? How far does the puck travel during the 5.00 s interval?” You can click over to the link if you want the solution.

What struck me was that the approach to the problem was all wrong. It looked at the problem the way students normally look at this kind of problem: by seeing what equations are around and then plugging them in. Of course, given the question, this is exactly what the student was expected to do. I mean, who would care what the average acceleration was? It’s such an incredibly boring way of looking at the problem.

The nature of the problem is energy balance. There are two kinds of energy: the kinetic energy of the puck and the heat energy of the friction. When I used to work with graduate students, I would throw in potential energy as well and have them do the problem with energy and force and show that they were the same. The point of such problems should be to understand the nature of physical phenomena, so math shouldn’t be of much concern.

When I taught undergraduate physics, I would often hear from my students that they understood the physics but were just having trouble with the math. Well, that wasn’t true. In fact, they were very often doing just fine with the math and it was the physics where they were hopeless. But it did make me see that surprisingly little physics was being taught in physics classes. And I worked to take as much math out of my classes as possible. Math should generally be the thing the student introduces late into the process of solving problems — not at the beginning.

Let’s look at our problem here. The essence of the problem is this:

ke0 = ke1 + heat

In this “ke” is the kinetic energy (½m×v2) of the puck at the beginning and the end. And “heat” the energy lost to friction that happens to be equal to μ×m×g×x. I would give 80% credit for that much because the concept we are dealing with is the conservation of energy. But the whole solution requires understand how objects move under constant acceleration. It’s just that it isn’t all that important.

Sadly, most teachers would not grade this problem in this way. They know that it is a conservation of energy problem, but in grading it, they get lost in the details of the problem’s solution. And you see this in questions. There is not even any mention of energy or force. This is why people leave physics courses thinking that the subject has no relevance to their regular lives. I can’t wait at a bus stop without doing a little physics to find the best place to stand. Physics is life. And most physics teachers do not help people to see that.

F W Murnau

F W MurnauOn this day in 1888, the great German filmmaker F W Murnau was born. He started in film right around the time when it had come into its all as an artistic medium. And his films are always quite beautiful to look at. He had a great eye. But he is best known for the mood of his work — he is one of major figures in German Expressionistic cinema. And like others in that movement, he was very interested in horror. This first film was based upon The Picture of Dorian Gray. He later did adaptations of Dr Jekyll and Mr Hyde and Faust.

He is best know, however, for his horror classic, Nosferatu, a Symphony of Horror — one of the first true horror films. Of course, like all of his films, he never got the rights to make the film. And in this case, it brought legal action from Bram Stoker’s widow. As a result, the film never had the chance to be commercially successful. But it is considered a classic today. All prints of the film were supposed to be destroyed. Luckily, one was saved.

Sadly, the same cannot be said of many of Murnau’s films. His first six films have been lost except for some minor fragments. And three of his later films are lost. This includes one he made in Hollywood, 4 Devils — which is thought by film historians to have been one of his best works. In all, he directed 21 films and nine of them are lost — almost half! That’s shocking for a major filmmaker of such a late date. And these are all feature films — 50 minutes and longer.

Still, you can find many of his films on the internet: Nosferatu, Faust, Tabu. And that’s a lot more than you can say for a lot of people. There are many whose films exist but no one cares enough to release them or put them online. I especially recommend checking out Tabu, because it shows a different side of Murnau than we normally see and you get a good feel for his keen visual sense.

Happy birthday F W Murnau!
