Science/Geek awesomeness
Here is a collection of cool images and charts.
Here is a sample:

Mortgage Crisis: banks are sometimes foreclosing on properties that they don’t have the title to!
The story so far: An epic housing bust and sustained high unemployment have led to an epidemic of default, with millions of homeowners falling behind on mortgage payments. So servicers — the companies that collect payments on behalf of mortgage owners — have been foreclosing on many mortgages, seizing many homes.
But do they actually have the right to seize these homes? Horror stories have been proliferating, like the case of the Florida man whose home was taken even though he had no mortgage. More significantly, certain players have been ignoring the law. Courts have been approving foreclosures without requiring that mortgage servicers produce appropriate documentation; instead, they have relied on affidavits asserting that the papers are in order. And these affidavits were often produced by “robo-signers,” or low-level employees who had no idea whether their assertions were true.
Now an awful truth is becoming apparent: In many cases, the documentation doesn’t exist. In the frenzy of the bubble, much home lending was undertaken by fly-by-night companies trying to generate as much volume as possible. These loans were sold off to mortgage “trusts,” which, in turn, sliced and diced them into mortgage-backed securities. The trusts were legally required to obtain and hold the mortgage notes that specified the borrowers’ obligations. But it’s now apparent that such niceties were frequently neglected. And this means that many of the foreclosures now taking place are, in fact, illegal.
This is very, very bad. For one thing, it’s a near certainty that significant numbers of borrowers are being defrauded — charged fees they don’t actually owe, declared in default when, by the terms of their loan agreements, they aren’t.
So the response?
True to form, the Obama administration’s response has been to oppose any action that might upset the banks, like a temporary moratorium on foreclosures while some of the issues are resolved. Instead, it is asking the banks, very nicely, to behave better and clean up their act. I mean, that’s worked so well in the past, right?
The response from the right is, however, even worse. Republicans in Congress are lying low, but conservative commentators like those at The Wall Street Journal’s editorial page have come out dismissing the lack of proper documents as a triviality. In effect, they’re saying that if a bank says it owns your house, we should just take its word. To me, this evokes the days when noblemen felt free to take whatever they wanted, knowing that peasants had no standing in the courts. But then, I suspect that some people regard those as the good old days.
What should be happening? The excesses of the bubble years have created a legal morass, in which property rights are ill defined because nobody has proper documentation. And where no clear property rights exist, it’s the government’s job to create them.
That won’t be easy, but there are good ideas out there. For example, the Center for American Progress has proposed giving mortgage counselors and other public entities the power to modify troubled loans directly, with their judgment standing unless appealed by the mortgage servicer. This would do a lot to clarify matters and help extract us from the morass.
We’ll see; but for now if someone tries to kick you out of your home, get a lawyer and ask to see the documentation.
Science, religion and stochastic factors
Jerry Coyne wrote an op-ed in USA today about how science and religion are incompatible. He then shared some of the feedback:
I want to briefly highlight one because its claim that I made a philosophical boo-boo has also appeared at several places on the internet:
Interesting but flawed argument
Jerry Coyne delivers a bold perspective on the compatibility of science and religion. He argues that a scientific viewpoint is contradictory to, and clearly trumps, a religious world view.
However, in his zeal to argue his point, he creates his own internal contradictions. He states that the existence of religious scientists cannot be used to support the compatibility of science and religion, and yet later he states that the incompatibility of science and faith is “amply demonstrated by the high rate of atheism among scientists.”
Before Coyne can convincingly argue that science and religion are incompatible, he needs to take care of the incompatibilities in his own viewpoint.

I find this argument curious. My claim was that science and faith are philosophically incompatible. If there were to be evidence for such a philosophical claim, then it would not be that every scientist would be an atheist. Rather, we’d expect that scientists would tend to be more atheistic than the general public.
People simply don’t understand what a stochastic factor is. Here is an example: we could show that height is an advantage in basketball; one bit of evidence would be to measure the average height of an NBA player and compare that to the average height of someone in the public. BUT, there might well be a Spud Webb or Muggsy Bogues who would be an outlier (exception to the rule).
You see the same thing when people discuss the relevance of college entrance scores. True, there are some who score in the 30′s on their ACT and still flop and a few who might score in the teens but make it through. But if you look at 1000 random students with an ACT of 30 versus 1000 random students with ACT of 20, the first group will have more successes. But the first group will have some failures and the second group will have some successes.

Another old vacation photo
Again, from 1984. I had a day at Sea World and took some photos. As I was lining up a shot of an aquatic animal these individuals got in front of me…so I went ahead and took the photo:

I didn’t post much today but I did write this post about the “method of undetermined coefficients” for solving inhomogeneous second order linear differential equations with constant coefficients.
